Photo: USGS/HVO Rock is flowing once again on Hawaii’s big island, where geologic change is not a matter of centuries and millennia, but rather of hours and days. Every square inch of these Hawaiian islands owes its existence to a hot spot that conduits molten rock from deep inside Earth to the surface.

    The New York Magazine‘s new Science of Us section has an interesting review of a new documentary on hotlines – whether they be for suicide support or phone sex. I was initially annoyed at the fact that the documentary puts both of these in the same category but it’s based on the interesting premise that hotlines – whether for mental health, sex or supporting members of a particular marginalised community – often involve the common component of lonely people reaching out to connect with a stranger, briefly, through conversation.

    Is it oversharing to tell you I wasn’t breastfed as an infant? Tough. I don’t feel that being bottlefed formula milk did me any harm. Breastfeeding is natural but it’s not always possible for new mothers and the push from the healthcare workers for breast is best waxes and wanes as any social fashion. There is a lot of guilt poured on mothers who (a) choose to breast feed their infant (b) choose not to breast feed their infant (c) cannot breast feed their infant. Take your pick, there’s guilt from every angle. If it’s physiologically possible it should be every…

  • Day care moves can be tough on kids

    Dave Shaw-UNC
    24 Nov 2014 | 3:02 am
    A study of more than 1,300 young children finds that shifting from one day care setting to another can have a negative effect on a child’s ability to make social connections by the time they’re in kindergarten. However, the researchers found no evidence that a change in teachers has any lasting negative effects. “Our findings showed that when young children moved between child care settings, these transitions negatively affected their social adjustment,” says Mary Bratsch-Hines, investigator with the Frank Porter Graham Child Development Institute at University of…

    21 Nov 2014 | 10:52 am
    In 1952, a famous experiment mixed together chemicals that were present early in Earth’s history, then approximately replicated the environmental conditions on the planet at that time. The goal was to see if biologically relevant organic molecules would form spontaneously. That work, the Urey-Miller experiment, produced more than 20 molecules that are important to life, but a team of chemists thinks it can do one step better. The group has built a computer model that can not only determine all the possible products of the Urey-Miller experiment, but also detail all the possible chemical…
  • Loss of elephants (and their poop) devastates forests

    Gigi Marino-Florida
    21 Nov 2014 | 9:37 am
    Elephants in Thailand have traditionally been hunted, mostly for fabled properties of their organs, teeth, and tusks. But a new study shows that overhunting has been disastrous for their tropical forest habitats. Elephants disperse lots of seeds across the forest. The dramatic loss of elephants increases the probability of tree extinction by more than tenfold over a 100-year period—a process that will likely cascade to other kinds of forest life, researchers predict.

In the early stages, AMD is characterized by the presence of small fatty deposits called drusen and thickening in a membrane at the back of the eye. “These findings suggest treating people with AMD with this new nanosecond laser reduces signs of the disease, ” says Erica Fletcher, associate professor of anatomy and neuroscience at the University of Melbourne.

  • GEDi: Genetic Test For Inherited Eye Disease Highly Accurate

    News Staff
    23 Nov 2014 | 10:43 am
    The retina is the neural tissue in the back of the eye that initiates vision. It is responsible for receiving light signals and converting them into neurologic signals, which are then transmitted via the optic nerve to the brain so that we can see. Mutations that disrupt vision by damaging the retina and optic nerve have been identified in more than 200 genes. This genetic diversity made genetic diagnostic testing difficult until the recent development of high throughput genomic techniques. read more

    Sometimes you don't need to travel to the unexplored corners of the globe to discover a new species of plant. Sometimes they can be really close to home, you just have to spend 40 years of your life looking. University of South Carolina Professor John Nelson and alumnus Douglas Rayner have founds just such a new species close to home and they have dubbed it Stachys caroliniana, a new example of what is commonly called a hedge-nettle or woundwort. And rarity is unusual among S. caroliniana's closest relatives. There are about 300 species in the genus Stachys, according to Nelson, the curator…
  • Little Considered: Treatment Of Transgendered Prison Inmates

    22 Nov 2014 | 10:18 am
    It's pretty common in culture, from Turkey to Tennessee, for a public that otherwise does not condone rape to joke about it when it comes to male criminals. And the more heinous the crime, not only does it become acceptable, but almost demanded in a justice system that often favors criminals over victims. But raping women isn't acceptable in civilized countries. In the modern decade, 'gender' has become a subjective thing. Anthropology papers will even strangely let 'other', including alien life forms, be considered a valid gender in their surveys. read more

Bottom line: make the thrill of the ameliorative, the joy of small reliefs, of the case solved and mystery dissipated and the worry ended, for now – to make those things as sufficient to live by as they are…

    On Friday, the FDA announced that it would start developing a stockpile of blood plasma from Ebola survivors, treated with a pathogen inactivation system that's never been used before in the US. So far, the United States has had some amazing success in curing Ebola, possibly thanks to experimental plasma treatments. Drawn from survivors, the stuff comes enriched in antibodies that could help to fight off the disease—but it also has the potential to carry other diseases, like malaria, that are common in west Africa where Ebola is raging.

    I’ve been puzzling over this tweet from Jeff Rouder: Surely, I thought, psychology is built out of effects. What could be wrong with focussing on testing which ones are reliable? But I think I’ve got it now. The thing about effects is that they show you – an experimental psychologist – can construct a situation where some factor you are interested in is important, relative to all the other factors (which you have managed to hold constant). To see why this might be a problem, consider this paper by Tsay (2013): “Sight over sound in the judgment of music…

He makes a good case, at least to this biologist’s eyes, and it seems reasonable. Natural Nuclear Reactors formed and operated on Earth, there is no reason this could not have happened on Mars.

However, determining which adaptive mechanisms facilitated its expansion remains an open question. Here we show, using the gyrencephaly index (GI) and other physiological and life-history data for 102 mammalian species, that gyrencephaly is an ancestral mammalian trait. We find that variation in GI does not evolve linearly across species, but that mammals constitute two principal groups above and below a GI threshold value of 1.5, approximately equal to…

    by Beth L. Pruitt, Alexander R. Dunn, William I. Weis, W. James Nelson External forces play complex roles in cell organization, fate, and homeostasis. Changes in these forces, or how cells respond to them, can result in abnormal embryonic development and diseases in adults. How cells sense and respond to these mechanical stimuli requires an understanding of the biophysical principles that underlie changes in protein conformation and result in alterations in the organization and function of cells and tissues. Here, we discuss mechano-transduction as it applies to protein conformation, cellular…
  • Modulation of the Maladaptive Stress Response to Manage Diseases of Protein Folding

  • High-Fidelity Coding with Correlated Neurons

    Rava Azeredo da Silveira et al.
    20 Nov 2014 | 2:00 pm
    by Rava Azeredo da Silveira, Michael J. Berry Positive correlations in the activity of neurons are widely observed in the brain. Previous studies have shown these correlations to be detrimental to the fidelity of population codes, or at best marginally favorable compared to independent codes. Here, we show that positive correlations can enhance coding performance by astronomical factors. Specifically, the probability of discrimination error can be suppressed by many orders of magnitude. Likewise, the number of stimuli encoded—the capacity—can be enhanced more than tenfold. These effects…
  • Estimating Relative Changes of Metabolic Fluxes

    Lei Huang et al.
    20 Nov 2014 | 2:00 pm
    by Lei Huang, Dongsung Kim, Xiaojing Liu, Christopher R. Myers, Jason W. Locasale Fluxes are the central trait of metabolism and Kinetic Flux Profiling (KFP) is an effective method of measuring them. To generalize its applicability, we present an extension of the method that estimates the relative changes of fluxes using only relative quantitation of 13C-labeled metabolites. Such features are directly tailored to the more common experiment that performs only relative quantitation and compares fluxes between two conditions. We call our extension rKFP. Moreover, we examine the effects of common…
  • BiomeNet: A Bayesian Model for Inference of Metabolic Divergence among Microbial Communities

    Mahdi Shafiei et al.
    20 Nov 2014 | 2:00 pm
    by Mahdi Shafiei, Katherine A. Dunn, Hugh Chipman, Hong Gu, Joseph P. Bielawski Metagenomics yields enormous numbers of microbial sequences that can be assigned a metabolic function. Using such data to infer community-level metabolic divergence is hindered by the lack of a suitable statistical framework. Here, we describe a novel hierarchical Bayesian model, called BiomeNet (Bayesian inference of metabolic networks), for inferring differential prevalence of metabolic subnetworks among microbial communities. To infer the structure of community-level metabolic interactions, BiomeNet applies a…

    Michael Mak et al.
    20 Nov 2014 | 2:00 pm
    by Michael Mak, Roger D. Kamm, Muhammad H. Zaman Dimensionality is a fundamental component that can have profound implications on the characteristics of physical systems. In cell biology, however, the majority of studies on cell physical properties, from rheology to force generation to migration, have been performed on 2D substrates, and it is not clear how a more realistic 3D environment influences cell properties. Here, we develop an integrated approach and demonstrate the combination of mitochondria-tracking microrheology, microfluidics, and Brownian dynamics simulations to explore the…

Iyer, Ewan Birney Associating genetic variation with quantitative measures of gene regulation offers a way to bridge the gap between genotype and complex phenotypes. In order to identify quantitative trait loci (QTLs) that influence the binding of a transcription factor in humans, we measured binding of the multifunctional transcription and chromatin factor CTCF in 51 HapMap cell lines. We identified thousands…
  • Heat-Induced Release of Epigenetic Silencing Reveals the Concealed Role of an Imprinted Plant Gene

    Diego H. Sanchez et al.
    20 Nov 2014 | 2:00 pm
    by Diego H. Sanchez, Jerzy Paszkowski Epigenetic mechanisms suppress the transcription of transposons and DNA repeats; however, this suppression can be transiently released under prolonged heat stress. Here we show that the Arabidopsis thaliana imprinted gene SDC, which is silent during vegetative growth due to DNA methylation, is activated by heat and contributes to recovery from stress. SDC activation seems to involve epigenetic mechanisms but not canonical heat-shock perception and signaling. The heat-mediated transcriptional induction of SDC occurs particularly in young developing leaves…
  • Three RNA Binding Proteins Form a Complex to Promote Differentiation of Germline Stem Cell Lineage in Drosophila

    Di Chen et al.
    20 Nov 2014 | 2:00 pm
    by Di Chen, Chan Wu, Shaowei Zhao, Qing Geng, Yu Gao, Xin Li, Yang Zhang, Zhaohui Wang In regenerative tissues, one of the strategies to protect stem cells from genetic aberrations, potentially caused by frequent cell division, is to transiently expand the stem cell daughters before further differentiation. However, failure to exit the transit amplification may lead to overgrowth, and the molecular mechanism governing this regulation remains vague. In a Drosophila mutagenesis screen for factors involved in the regulation of germline stem cell (GSC) lineage, we isolated a mutation in the gene…
  • An RNA-Seq Screen of the Drosophila Antenna Identifies a Transporter Necessary for Ammonia Detection

    Karen Menuz et al.
    20 Nov 2014 | 2:00 pm
    by Karen Menuz, Nikki K. Larter, Joori Park, John R. Carlson Many insect vectors of disease detect their hosts through olfactory cues, and thus it is of great interest to understand better how odors are encoded. However, little is known about the molecular underpinnings that support the unique function of coeloconic sensilla, an ancient and conserved class of sensilla that detect amines and acids, including components of human odor that are cues for many insect vectors. Here, we generate antennal transcriptome databases both for wild type Drosophila and for a mutant that lacks coeloconic…

    by Qing Yao, Li Zhang, Xiaobo Wan, Jing Chen, Liyan Hu, Xiaojun Ding, Lin Li, Jayashree Karar, Hongzhuang Peng, She Chen, Niu Huang, Frank J. Rauscher, Feng Shao Enteropathogenic E. coli (EPEC) and related enterobacteria rely on a type III secretion system (T3SS) effector NleE to block host NF-κB signaling. NleE is a first in class, novel S-adenosyl-L-methionine (SAM)-dependent methyltransferase that methylates a zinc-coordinating cysteine in the Npl4-like Zinc Finger (NZF) domains in TAB2/3 adaptors in the NF-κB pathway, but its mechanism of action and other human substrates are unknown.

    by Travis Hartman, Brian Weinrick, Catherine Vilchèze, Michael Berney, Joanne Tufariello, Gregory M. Cook, William R. Jacobs In chronic infection, Mycobacterium tuberculosis bacilli are thought to enter a metabolic program that provides sufficient energy for maintenance of the protonmotive force, but is insufficient to meet the demands of cellular growth. We sought to understand this metabolic downshift genetically by targeting succinate dehydrogenase, the enzyme which couples the growth processes controlled by the TCA cycle with the energy production resulting from the electron transport…

  • PKDL and Other Dermal Lesions in HIV Co-infected Patients with Leishmaniasis: Review of Clinical Presentation in Relation to Immune Responses

    Eduard E. Zijlstra
    20 Nov 2014 | 2:00 pm
    by Eduard E. Zijlstra Background Co-infection of leishmaniasis and HIV is increasingly reported. The clinical presentation of leishmaniasis is determined by the host immune response to the parasite; as a consequence, this presentation will be influenced by HIV-induced immunosuppression. As leishmaniasis commonly affects the skin, increasing immunosuppression changes the clinical presentation, such as in post-kala-azar dermal leishmaniasis (PKDL) and cutaneous leishmaniasis (CL); dermal lesions are also commonly reported in visceral leishmaniasis (VL) and HIV co-infection. Methods We reviewed…

    Despite the frequent use of choropleth maps online, they're still kind of tricky to produce for beginners. Landline, an open source JavaScript library from ProPublica, aims to make it a little bit easier. Given a GeoJSON file, Landline provides an interactive choropleth map with tooltips that works on multiple devices. Still in its early stages, the library lets you make state and county maps, as well as customize to your own needs. Underscore.js and Raphael.js are its two dependencies, so it plays nice with those libraries also. Tags: choropleth, javascript, ProPublica

    Imperiled species reproduces in a quiet refuge Why does the white rhino breed in the Fossil Rim Wildlife Center? The answer could be blowing in the wind. Sound, like sight and scent, affects animal behavior – but scientists are only now starting to focus on sound in captive environments. Photo: Fossil Rim Wildlife Center Many zoos and wildlife parks have replaced cages with more natural enclosures, but they may be paying less attention than they should to sound, says Suzi Wiseman, a graduate student in environmental geography at Texas State University-San Marcos. At last week’s meeting of…

    Stem cell advance Photoreceptors in the retina detect light and send nerve signals to the brain. The retinal pigment epithelium keeps the photoreceptors healthy. When it dies in age-related macular degeneration, the light detectors die as well. A new study that implanted new RPE cells raises new hope for stem-cell therapy. Graphic: Edited from orginal by National Eye Institute, National Institutes of Health A field long on promise and short on healing was energized on Oct. 15, 2014, when The Lancet reported on the transplant of retinal cells into 18 people who were blind because cells had…

    23 Oct 2014 | 3:05 pm
    Cold-War exclusive: Cuban lizards invade Florida A new study of lizards along Florida’s Atlantic Coast shows that a long- lasting genetic change — evolution — can occur in just 20 generations. Scientists have seen evolution among microbes or fruitflies in the lab, but demonstrating a change in gene structure is more difficult for larger organisms living beyond the lab. For decades, native Anolis carolinensis lizards have lived on islands built of sediment dredged during construction of the Intracoastal Waterway. In the 1940s, the closely related Cuban brown anole lizard…

    Ann Gibbons
    20 Nov 2014 | 4:00 pm
    Why do humans have skin of various colors? Anthropologist Nina Jablonski explains that it's all about sunlight. As modern humans spread out of Africa in the past 60,000 years, they adapted to the varying natural light they encountered, from the twilight of northern winters to the blazing sun of the equator, and their originally dark skin evolved into a sepia rainbow. Jablonski has popularized this evolutionary history in countless radio and TV interviews, two popular books, and a TED talk viewed by nearly 700,000 people online. She argues that our skin color has crucial implications for…

    Olwen Reina
    20 Nov 2014 | 11:30 pm
    SLIC, or sequence and ligase independent cloning, was developed by Li in 2007 and published in Nature Methods. What makes it a Nature Methods worthy protocol? Unlike other forms of cloning, SLIC does not require restriction enzymes or a ligase! Seriously! Don’t believe me? Why not have a go for yourself? I've detailed the main steps below to get you started. How it works To use SLIC for cloning, you first amplify a DNA fragment by PCR. You perform the PCR using specially-designed oligonucleotides that have a 25-base pair sequence on their 5’ termini that is homologous to…

If you are taking public transport, you can use that time to answer those emails you don’t have time to get to at the office/lab, or to catch up on reading some papers that you could use for journal club or your own research. Instead of looking at your commute as part of your workday, or yet another added stress, you could use your commute to relax, and act as a buffer between work and home. Using your travel time to de-stress after a hard day can be beneficial.

You've harvested your cells and gently lysed them, now you're ready to look at the proteins. What's one of the most common next step in protein analysis? A denaturing gel or SDS-Polyacrylamide Gel Electrophoresis! SDS-Polyacrylamide Gel Electrophoresis, or SDS-PAGE for short, is the technique where proteins are denatured and linearized, then run across a current through a thin gel, which separates the proteins by size.

    Do you suspect that your favourite protein is doing something really cool? But you cannot see it because your confocal microscope’s resolution is limited. Then Stimulated Emission Depletion (STED) microscopy is what you need! With the power to smash through the diffraction limit of confocal microscopy, STED opens up a whole new world of improved sub-cellular resolution without the need for extensive post-image processing. Last month I gave you an overview of STED microscopy in part 1 of the ‘Who’s who of super-resolution microscopy’. In this series of articles on STED microscopy, I…

    At the beginning of the 19th century women in the United States had an average of seven or eight children. By 1900 they had only three or four, and today 35% of American women have exactly two. How did this happen? This episode of Distillations explores the role technology has played in reproduction, and how it has affected the ethical and moral landscape that surrounds it. First, reporter Allison Quantz talks to her sister to find out what she plans to do with her extra frozen embryos. Along the way Quantz learns that there are more than one million frozen embryos in the United States with…

By the end of the talk, the answer was clear. “Probably not, but you should still be careful.” The world’s felines have something in common, a trait shared by both domestic housecats and lions in the African savannah: they carry the parasite Toxoplasma gondii, a highly infectious protozoan that can spread to most warm-blooded mammals, including humans. Felines have been the natural host of T. gondii’s reproduction cycle for…

  • Your family tree just got a little bit more complicated....

    7 Nov 2014 | 11:03 am
    Your family tree just got a little bit more complicated. Scientists recently confirmed that the DNA found in the fossil of a 45,000-year-old human contains traces ofNeanderthal DNA. The fossilized bones were discovered near the Irtysh River in Siberia in 2008. Based on the amount of Neanderthal genetic material in the fossil, researchers believe that humans interbred with Neanderthals between60,000 and 50,000 years ago. The difficulty of sequencing ancient DNA cannot be overstated. As Sam Kean writes in the newest issue of Chemical Heritage, contamination, corruption, and chromosomal…

  • Cigarettes: More Dangerous Than Before

    The NIDA Blog Team
    20 Nov 2014 | 12:00 am
    Is there anyone that doesn’t know how dangerous smoking cigarettes can be? It’s hard to imagine with so much public education from The Truth Campaign, The Real Cost, and Tips From Former Smokers. But what a lot of people don’t know is that cigarettes have actually become more dangerous. A recent report from the U.S. Surgeon General—the Nation’s “top doctor”—relates that cigarettes are more toxic now than in the 1950s because tobacco companies have changed the design and ingredients of cigarettes. As a result, both men and women have a much higher risk for lung cancer and…

In the 1920s, when the link to cancer was discovered, smoking was normal---in fact, ads for cigarettes even featured doctors saying it relieved stress! For years, people smoked in their homes and offices, in restaurants and stores, on planes and on trains. Wherever they went…they smoked.  In 1957, the nation’s top doctor—the U.S. Surgeon General—warned that cigarette smoking could cause lung cancer. Other government doctors began to speak…

  • Dirty Money: How Cocaine and Germs Contaminate Our Cash

    6 Nov 2014 | 12:00 am
    Q: What do cocaine and bacteria have in common? A: They both contaminate our cash. While most of the dollar bills you come into contact with would test positive for cocaine, that doesn’t mean that they were used to snort cocaine. In fact, less than 1 percent of people age 12 or older even use the drug.   It happens because cocaine is a very fine powder that easily transfers from bill to bill. One bill with cocaine on it can contaminate an entire cash drawer or ATM. It’s a little like someone with a cold—if he or she sneezes on you, the chances are good that you’ll catch what the…

Once the audience voting has…
  • I think you've had enough, Mr. Bond

    11 Jul 2014 | 11:12 pm
    James Bond is likely to be impotent, at high risk of liver disease, and the fact he likes his martini "shaken, not stirred" is because of alcohol-induced tremors.If you weren't already convinced that a real-life James Bond would be a terrible spy - he tells people his actual name for goodness sake - the article Were James Bond’s drinks shaken because of alcohol induced tremor? outlines the likely health issues Britain's most famous fictional spy would be suffering in real life due to his outrageous alcoholism.The researchers read all 14 James Bond books and noted down each time he had a…
  • ABC Radio - June - Mars One

    20 Jun 2014 | 4:23 am
    I've been doing quite a bit of regular radio with the ABC recently (ABC Riverina and ABC Central West), so I thought it would be a good idea to put up a post each month on what we've spoken about.The main topic this month was the Mars One project, which plans to establish a permanent human settlement on Mars. This is an incredibly optimistic project, made even more interesting by the fact that it is going to be funded by a reality TV show, which will track the training and lives of the astronauts, and presumably follow them into space. A number of Australians are still in the running to be…
  • Some life analysis with Twitter

    30 May 2014 | 4:11 pm
    There was a great post recently on Flowing Data, The Change My Son Brought, Seen Through Personal Data. It got me thinking about what my life looks like through personal data and probably the best source of data since the advent of smartphones is Twitter. Twitter recently made it possible to download your personal archive and it makes for some interesting analysis. Along with RSS feeds, Twitter is my major source of online news, education and entertainment, and it is also useful for personal communications and microblogging.Downloading your personal archive is easy, but you need to do a…

  • Mutant protein takes babies' breath away

    23 Nov 2014 | 9:00 pm
    Researchers had never shown exactly how cells in the brain stem detect carbon dioxide and regulate breathing in humans. After taking a mutation from a two-month-old baby and expressing it in human astrocytes, they did exactly that -- and the research may lead to an early warning system to save premature infants with breathing trouble.
  • The sound of status: People know high-power voices when they hear them

    23 Nov 2014 | 9:00 pm
    Being in a position of power can fundamentally change the way you speak, altering basic acoustic properties of the voice, and other people are able to pick up on these vocal cues to know who is really in charge, according to new research published in Psychological Science, a journal of the Association for Psychological Science.

  • Schizophrenia may be triggered by excess protein during brain development

    23 Nov 2014 | 9:00 pm
    A gene associated with schizophrenia plays a role in brain development and may help to explain the biological process of the disease, according to new Rutgers research. Bonnie Firestein, professor in the Department of Cell Biology and Neuroscience, says too much protein expressed by the NOS1AP gene, which has been associated with schizophrenia, causes abnormalities in brain structure and faulty connections between nerve cells that prevent them from communicating properly.
  • Motor coordination issues in autism are caused by abnormal neural connections

    23 Nov 2014 | 9:00 pm
    Abnormal connections between neurons are the likely cause of motor coordination issues seen in autism spectrum disorder. Using a mouse model of autism, scientists from the University of Chicago identified a malfunctioning neural circuit associated with reduced capacity for motor learning. This appears to arise from an inability to eliminate unneeded neural connections in the brain. They report their findings Nov. 24 in Nature Communications.

    “We want to find out whether spacetime is a quantum system just like matter is,” said Craig Hogan, director of Fermilab’s Center for Particle Astrophysics and the developer of the holographic noise theory. “If we see something, it will completely change ideas about space we’ve used for thousands of years.” Much like characters on a television show would not know that their seemingly 3 - D world exists only on a 2 - D screen, we could be clueless that our 3 - D space is just an illusion. The information about everything in our universe could actually be encoded in tiny packets in…
  • NASA's New View of Jupiter's Ocean Moon --Is Europa the Solar System's Best Bet for Life?

    22 Nov 2014 | 7:48 am
    The puzzling, fascinating surface of Jupiter's icy moon Europa looms large in this newly-reprocessed color view, made from images taken by NASA's Galileo spacecraft in the late 1990s. This is the color view of Europa from Galileo that shows the largest portion of the moon's surface at the highest resolution. Scientists have produced this new version of what is perhaps NASA's best view Europa. The mosaic of color images was obtained in the late 1990s by NASA's Galileo spacecraft. This is the first time that NASA is publishing a version of the scene produced using modern image processing…
  • The Science Behind "Interstellar's" Stunning Wormhole Voyage (Weekend Feature)

    dailygalaxy.com
    22 Nov 2014 | 7:00 am
    Similar in premise to many other science fiction films, something sets Interstellar apart: Many of the images are--for the most part--scientifically accurate, based on lensing calculations produced by Cornell University and California Institute of Technology scientists that show what black holes or wormholes look like. At this point, the blockbuster movie has created such a stir that one would almost have to be inside a black hole not to know about it. And while the science fiction thriller may have taken some liberties with science to make its Hollywood plot work, the imagery comes straight…

    21 Nov 2014 | 9:11 am
    Betelgeuse is one of the most massive known stars, almost the size of the orbit of Jupiter, surrounded by a nebula, which is much bigger than the supergiant itself, stretching 60 billion kilometres away from the star's surface — about 400 times the distance of the Earth from the Sun. Red supergiants like Betelgeuse represent one of the last stages in the life of a massive star in which the star increases in size, and expels material into space at a tremendous rate — it sheds immense quantities of material equal to the mass of the Sun in just 10 000 years. In a discovery decades in the…

    In 1960, the astronomer Francis Drake pointed a radio telescope located in Green Bank, West Virginia, toward two Sun-like stars 11 light years away. His hope: to pick up a signal that would prove intelligent life might be out there. Fifty years have gone by since Drake’s pioneering SETI experiment, and we’ve yet to hear from the aliens.mmBut thanks to a host of discoveries, the idea that life might exist beyond Earth now seems more plausible than ever. For one, we’ve learned that life can thrive in the most extreme environments here on Earth — from deep-sea methane seep and Antarctic…

  • Ingredient Focus: Nuts and Seeds

    3 Nov 2014 | 3:59 am
    Nuts and seeds pack quite a few vitamins (such as folate and vitamin E) and minerals, along with fiber and protein, in their small sizes. Nuts, in particular, also contain quite a bit of fat. Luckily, most of the fat (except in walnuts) is monounsaturated. Walnuts and flaxseed are rich in the omega-3 fatty acid linolenic acid, an essential fatty acid. One ounce of many nuts contains from 13 to 18 grams of fat, making them also a relatively high-kcalorie food. By comparison, seeds contain less fat and more fiber but still quite a few kcalories. Nuts and seeds also contain many…
  • Water

    2 Nov 2014 | 1:03 am
    The average adult's body weight is generally 50 to 60 percent water—enough, if it were bottled, to fill 40 to 50 quarts. For example, in a 150pound man, water accounts for about 90 pounds and fat about 30 pounds, with protein, carbohydrates, vitamins, and minerals making up the balance. Men generally have more water than women, a lean person more than an obese person. Some parts of the body have more water than others. Human blood is about 92 percent water, muscle and brain tissue about 75 percent, and bone 22 percent.The body uses water for virtually all its functions: digestion,…

  • Food Contaminants

    13 Sep 2014 | 5:20 pm
    There is a greater reason than aesthetics to insist on clean hands at all times. Salmonella, the most common form of food poisoning and one that can kill the elderly and infirm, is often transmitted by urine. Diarrhea and dysentery often come from feces.However, the good news is that the least likely source of food poisoning is a dirty person. The classic case of “Typhoid Mary,” an itinerant dishwasher who spread typhoid wherever she worked, is long gone.Far more dangerous are bad food storage disciplines. Raw meat and cooked meat must not collide. A butcher or chef who has handled raw…

    In this section we will look at the main types of alternative fuels. We start with Biofuels as this constitutes probably the most popular AF currently in use.BiofuelsMuch recent attention has been focused on biofuels. This is highlighted economically by the fact that worldwide investment in biofuels rose from US$5bn in 1995 to US$38bn in 2005, owing to substantial investments by companies such as BP, Shell and Ford, and by Richard Branson (Grunwald, 2008).Biofuels are essentially fuels produced from renewable plant material and oils.

  • Calcium Loss Turning Canadian Lakes Into “Jelly”

    Daniel Kelly
    20 Nov 2014 | 7:56 am
    Beginning with the industrial revolution, calcium levels in Canadian lakes have been going down, according to research published in the journal Proceedings of the Royal Society B. The drop is due to increased lake acidity, scientists say, and is contributing to a rise in plankton that’s giving lakes there a jelly-like consistency. Investigators led by Queen University, York University and the University of Cambridge made the find using sediment cores from 36 lakes in southern Ontario. In cores from 25 of the lakes, scientists saw gradual increases in holopedium – a jelly-clad plankton…
  • Changing Winds Key To Studying Lake Tahoe’s Currents

    Scientists at the Tahoe Environmental Research Center say that Lake Tahoe is all but calm underneath the surface, according to the Nevada Appeal. And though its currents are broadly fickle, experts at the center are working to better predict how they change. Why is it important to know what Tahoe’s currents are doing? “Lake motions are important,” said Geoff Schladow, director of the TERC to the Nevada Appeal. “It’s the currents, it’s the motions, that transport everything in the water.” In other words, knowing how the water behaves beneath the surface helps scientists forecast…
  • San Francisco’s Mountain Lake Treated To Remove Invasive Fish

    After years of netting, trapping and electric stunning did little to rid San Francisco’s Mountain Lake of invasive fish, wildlife officials with the Presidio Trust decided to use poison treatment on the lake, according to the San Francisco Chronicle. The treatment, which only affected gilled organisms, was applied Nov. 12. Applying the poison, rotenone, didn’t take long – crews in charge of applying it only needed a morning. And not long after they released the mixture, ecologists following behind them were able to start pulling out carp, goldfish and other invasive fish dumped into…
  • Ecological Impacts Of Invasive Round Goby (Neogobius melanostomus) In The Laurentian Great Lakes And Beyond: Summary Of Presentations At IAGLR 2014

    Guest Submissions

    Aquatic invasive species (AIS) pose a significant threat to biodiversity and production from large-scaled lake and river ecosystems. AIS cause species extinctions, increase homogenization of biological communities, decrease native biotic resistance to disruptions, outcompete heterospecifics for limited prey, eat larvae or eggs of natives and parasitize native hosts. One recent and now widespread successful invader in North American Laurentian Great Lakes (hereafter Great Lakes) and many large European waterbodies is the Ponto-Caspian round goby (Neogobius melanostomus; Figure 1).

    Of all the things lake sediments have been used to study – like telling the history of the Spanish climate or showing the unyielding force of California drought – predicting the future likelihood of earthquakes is probably one of the most novel. Researchers at GNS Science in New Zealand recently put together a research summary for Lake Scientist describing an investigation looking at the probability of quakes near Lakes Mapourika and Paringa that sit along the country’s Alpine Fault. They’ve recently shot a video to further outline the research. Lake Mapourika. (Credit:…

    Listening in to a conversation can be easy if you have the right code in place. A. Strakey/Flickr, CC BY-NDYou don’t have to look far to see how many ways criminals can exploit mobile devices for nefarious purposes. From simple phishing scams to creating fake Wi-Fi networks, the methods in which data can be stolen from smartphones seem endless. In research to be published in the journal Computers & Security in February, colleagues at the University of South Australia and I showed it’s even possible to pick up data from Android devices by “listening” to sounds humans can’t hear.

    Webcams have been made public because their passwords weren't changed from the default. Flickr/Cory Doctorow, CC BY-NC-SAThere are concerns that thousands of private webcams around the world could be streaming live images to anybody who wishes to view them – without their owner knowing – thanks to a Russian website providing a convenient list of every camera that can be accessed. But how is the website doing this? Just like with those who had concerns over Facebook’s Messenger app, the website is exploiting the fact that most users accept the default settings on webcams.

  • Ice bath after exercise? The benefits might be in your head

    How much of an ice bath is a placebo? Andreas Nilsson/Flickr, CC BY-NC-NDWhether an athlete has endured the repeated joint stresses of a marathon run, or the relentless battery of hits during a football match, many will opt for a post-activity polar plunge into an ice-cold bath. There is method to this madness, though – many studies show that ice baths allow athletes to recover faster, train harder and ultimately perform better, and are thought to accelerate the body’s recovery, preparing it for the next gruelling training session. Given the subjective nature of muscle soreness, might the…

    Warmer waters heading south – here's sunrise off Manly in New South Wales. Flickr/Jeff Turner, CC BYOccasional erratic bursts southward of the East Australian Current (EAC) are thought to have moderated the weather of south-east Australia this autumn and winter and they continue to introduce tropical and sub-tropical marine species to Tasmanian waters. Ocean monitoring by Australia’s Integrated Marine Observing System is providing scientists with significant new insights into the changing structure of the EAC. Over the past 50 years sporadic warm bursts have become more common as the…

    I say theory, he says theory but what do you think we mean when we talk about theories, like Big Bang theory, the theory of evolution by natural selection, the theory of relativity (both general and special) and quantum theory. Well, we don’t mean it’s “just” a theory, like some vague idea a bloke down the pub came up with to explain the woes of the world, it’s not some conspiracy theory. If only we could’ve been more positive and used another word without the negative connotations of the man on the Clapham omnibus’ conception of the word…

    Is it oversharing to tell you I wasn’t breastfed as an infant? Tough. I don’t feel that being bottlefed formula milk did me any harm. Breastfeeding is natural but it’s not always possible for new mothers and the push from the healthcare workers for breast is best waxes and wanes as any social fashion. There is a lot of guilt poured on mothers who (a) choose to breast feed their infant (b) choose not to breast feed their infant (c) cannot breast feed their infant. Take your pick, there’s guilt from every angle. If it’s physiologically possible it should be every…

    This week’s BBC “Point of View” was purportedly humanist but is perhaps an age-old perspective that humanity has sought and found many times throughout history for living with less worry and hopefully overcoming existentialist angst at least temporarily. Adam Gopnik identifies four different types of anxiety that afflict modern people and suggests ways to cure them. Bottom line: make the thrill of the ameliorative, the joy of small reliefs, of the case solved and mystery dissipated and the worry ended, for now – to make those things as sufficient to live by as they are…

An evolutionary biologist at the University of Akron, Blackledge studies spiders and their webs, a topic that he finds endlessly fascinating. According to Blackledge, spiders get a bad rap. “In the United States, I think we’re kind of taught as children that we’re supposed to be afraid of them,” he says. “But they’re just an incredibly diverse group of animals that play incredibly important roles in our ecosystems as predators of insects.” Dr.

Although hydropower has been in use for centuries, largely in the form of water wheels, hydroelectricity is a more recent phenomenon. Hydroelectricity is a type of hydropower and is created as moving water powers machines that produce electricity. The first hydroelectric power plants were built at the end of the 19th century. By the middle of the 20th century they were a major source of electricity. Today hydropower is the most widely used source of renewable energy making up seven percent of U.S. power production.

    Biology concepts – protists, complexity, undulipodia, flagella, cilia, amoebas, Emotions are one of the things that make humans so complex. Memories attached to associations, stimulated by individualized brain chemistry makes it so you can’t predict how any one person might feel about a particular stimulus. But perhaps we are not so complex. A new study suggests that there are really only four human emotions, happy, sad, afraid, and mad. The other two commonly held states, disgusted and surprised are just sides of mad and afraid, respectively. Read the study and feel…… something.Are…

  • The answer is in the intergalactic wind

    LaboratoryNews
    24 Nov 2014 | 12:00 am
    Astronomers have observed the first direct evidence that an intergalactic “wind” is stripping galaxies of star-forming gas as they fall into clusters of galaxies. This explains why galaxies found in clusters have relatively little gas and less star formation compared to non-cluster or “field” galaxies. It was thought that as a field galaxy falls into a cluster of galaxies, it encounters a cloud of hot gas. As it moves through this intra-cluster medium, the cloud acts like a wind to blow away the gas within the galaxy without disturbing its stars – a process known as ram-pressure…

    The smallest member of the crew on board the Mary Rose – a dog named Hatch – was a he and not a she as previously believed. Hatch was discovered in 1981 during an underwater excavation of the famous ship, and lacked a baculum or penis bone, so was thought for many years to be female. New research from an international team of researchers, including the University of Portsmouth, has found that Hatch was actually a young male dog, most closely related to modern Jack Russell terriers, with a brown coat. “We extracted DNA from one of the dog’s teeth to identify the breed of the dog, its…

    If you’re anything like me, you have probably given only limited thought to the fluoride in your tap water. You probably have some vague idea that it’s there and that it relates to your dental health. But community water fluoridation is a fairly controversial practice. Some cities (Portland, Oregon, for example) have blocked the introduction of fluoride, and numerous advocacy groups call for its elimination all together.Those who support water fluoridation — a group that includes the Centers for Disease Control and Prevention, the American Academy of Pediatrics and the American…

    From time to time, without warning, more than 200 public health workers in Nevada get an urgent call on their cellphones.“We say, ‘You’re being called in,’ ” said Erin Seward, the state’s public health preparedness manager. “This is an emergency.”Generally, it’s not. It’s a drill aimed at testing how ready the state is for a public health emergency — whether an anthrax attack or a major outbreak of flu, for example. When the call comes, first responders from state, local and private agencies across Nevada’s 111,000 square miles practice distributing vaccines,…

They are almost always in pairs, alternating curves, unless there’s some geographical feature messing with the natural flow. From a hypothetical straight line river, these curves start forming when there’s even a slight aberration in the bank. Besides that thicker a streams make bigger curves. And smaller tributaries meander in tighter turns. This is what makes rivers (with their smaller tributaries turning…

  • Do You Believe This Testimony of Former NASA Worker Who Saw Humans On Mars? (Video)

    22 Nov 2014 | 3:05 am
    For over a century, mankind has speculated about life on Mars. In the past 10 years, the U.S. has put several rovers on Mars, which is how these images were taken. However, any person who says there are humans on Mars could be considered as insane. Does this photo show a human on Mars?   But what if there were testimonies? Evidences that could prove this possibility? Now, there is information about humans already having a base on Mars. This video makes some startling claims. In 1979, Jackie, a former worker for Viking mission, says she saw two men working on Mars. The former CIA…
  • This is How a Black Hole Gets Smashed Out of its Galaxy

    Ben Grinberg
    21 Nov 2014 | 2:21 pm
    Michael Koss wasn’t just searching for supermassive black holes, he was seeking twin supermassive black holes. Looking at satellite images, the astronomer found a speck of light 90 million light years from Earth, in a ‘dwarf galaxy‘ (Markarian 177, in the bowl of the Big Dipper). The possibly largest black hole so far found weighs 17 billion times more than the sun. This means that black holes are so massive, and have such huge gravitational pull, that they swallow anything that gets too close, including light, matter and gas. This process is so intense, fast, and massive,…

    There’s something about aluminum that’s just so appealing. Are you an aluminum lover? Maybe it’s the flexibility, the durability, the combination of the two in one super-metal. Check out Weird Al Yonkovic’s ‘Royals’ parody ‘Foil‘ to catch the love. But chances are that you’re already a fan since it’s found in just about everything, from cars, to planes, to iPhones, to cans. Get to know your aluminum with this infographic. (Or ‘aluminium’ as the Brits and Aussies prefer to say.) (Image: Guttermasters.com.au)

  • The Beginning: Out of the Sea

    Rick Coste
    24 Nov 2014 | 3:15 am
    Evolution Talk Evolution Talk - The Oldest Story Ever Told The sea was full of life a half a billion years ago. Arthropods fought to survive and there were some interesting things happening on land as well. We have here our first plants. And they spread like wildfire. The quiet life on land enjoyed by the plants looked appealing to that first vertebrate that poked its head out of the water as it supported itself with its new backbone and fins.

    Evolution Talk Evolution Talk - The Oldest Story Ever Told The reason natural selection had such a grand old-time with multicellular organisms is because it gave it something to select for. These organisms increased in size, moved into new areas for food, and protected themselves against the environment. It is during this period that some peculiar forms began to emerge.

    There are a lot of exciting things going on in November.  If you are not yet aware, we thought we’d fill you in so you can make the most out of enjoying the last few weeks of this month. November is the magical month where toy dinosaurs come to life at night and are inevitably discovered by their homo sapiens in the morning, having created all sorts of mischief.  This phenomenon is known as Dinovember.  November is also the time of year when men let their mustaches take center stage to raise awareness for men’s health.  That phenomenon is known as Movember.  Not ever wanting…
  • Dining With Dinosaur Giants: Sauropods

    Brian Switek
    10 Nov 2014 | 9:49 am
    I love living in dinosaur country. Not only are there plenty of bones to discover, but Mesozoic mysteries abound. And one of the most persistent has to do with the 150 million year old environments that are preserved here and there in eastern Utah. Those Late Jurassic sites are brimming with the bones of huge sauropods - long-necked, hefty dinosaurs such as Apatosaurus, Camarasaurus, and Diplodocus, just to name a few. In fact, there are so many species and individuals that paleontologists are left with a tough question: how did so many giants coexist? In general form, one sauropod might look…

    Dinovember is going to be here in just a few days! It’s a whole month dedicated to parents trying to convince their children that their dinosaurs come alive at night. It’s the time of year when toy dinosaurs take center stage and cause all kinds of ruckus. We think there are some toy dinos out there who would love to be spruced up for such an occasion.  Take this guy for example … Such obvious signs of wear and tear can start to make a dinosaur feel old!

  • The “Terrible Hands” Finally Get a Body. And it’s WEIRD.

    Brian Switek

    The better we get to know dinosaurs, the stranger they become. There’s no better example of that than Deinocheirus – an immense dinosaur whose arms generated paleontological speculation that didn’t even come close to the dinosaur’s bizarre reality. When I was a kid, Deinocheirus was mentioned in almost every dinosaur book. The dinosaur’s celebrity didn’t come from completeness, but from mystery. In the summer of 1965, while searching for fossils in the 70 million year old rock of the Gobi Desert, the palaeontologist Zofia Kielan-Jaworowska discovered an…
