    Stone tools made by our ancient ancestors have been dated to be around 3.3 million years old. Scientists have stated that this is a “new beginning to the known archaeological record.”  Scientists now believe that the dawn of culture has been pushed back by 700,000 years. This is a much earlier sign of human progress than previously known, and well before the first known member of our genus Homo.

  • Happy World Turtle day: How the turtle got its shell

    Eric Gershon-Yale
    23 May 2015 | 4:09 am
    New evidence pushes back the origin of the turtle’s shell by about 40 million years, linking it to a 260-million-year-old fossil reptile from South Africa. The connection to Eunotosaurus strengthens the fossil record and bolsters an existing theory about shell development while providing new details about its precise evolutionary pathway, researchers say. “Now we’ve got an intermediate shell, a transitional form that bridges the gap between turtles and other reptiles and helps explain how the turtle shell evolved,” says Tyler Lyson, a curatorial affiliate of the Peabody Museum…
  • Can good food protect your ears from loud noises?

    Morgan Sherburne-Florida
    22 May 2015 | 8:24 am
    A healthy diet may offer some protection from hearing loss due to noise exposure, however it can’t reverse hearing damage, a new study shows. Researchers examined the eating habits of 2,366 people who answered questionnaires about their health and were given a four-part hearing test. The findings showed a strong connection between a healthy diet, hearing, and noise exposure. The hearing of people who ate well but had higher noise exposure was comparable to the hearing of people with lower noise exposure who ate less healthy diets. For the study, published in the International…
  • Higher drug use among teens who go to raves

    Christopher James-NYU
    22 May 2015 | 7:58 am
    A new study finds that use of illegal drugs other than marijuana was about 20 percent higher among teenagers who attend raves, compared to those who don’t. In addition, those who go to raves were more likely to report more frequent use for each of 18 drugs asked about in a survey. Deaths among attendees of electronic dance music festivals (“raves”) have gone up in recent years, but no nationally representative studies have looked at potential associations between nightlife attendance and drug use. A new study, published in Drug and Alcohol Dependence, is the first to examine…
  • Smokers 4x more likely to be emergency room ‘super-users’

    Smokers are four times more likely than non-smokers to frequently visit emergency rooms. A new study, which explores how much patients replace visits to a primary care physician with a trip to a hospital emergency room, also shows Americans with chronic diseases use both services equally. In fact, overall, medical care visits of all types have soared in recent years. “There are a few super-users who have been in the ER 40 or 50 times, but when we step back and look at the whole population, we see a different pattern,” says Jessica Castner, assistant professor of nursing at…

  • Antibiotic Resistance: Phages Can Transfer It In Chicken Meat

    News Staff
    23 May 2015 | 9:30 am
    Antibiotic-resistant bacteria are on the rise and they pose a global threat to public health. Common antibiotics are often ineffective in treating infectious diseases because pathogens acquire resistance genes. These antimicrobial resistance genes are obtained in different ways. There are different explanations for how resistances are transferred and a now study found phages - viruses that exclusively infect bacteria - in chicken meat that are able to transfer antimicrobial resistance to bacteria.  Phages do not directly pose a risk to humans because they can only infect bacteria. No…

    The number of middle-aged men and women suffering a cerebral stroke has apparently risen significantly in the last decade or so. It seems that the press release from the Stroke Association making this pronouncement which has been widely reported almost verbatim by the media is based on NHS hospital admission statistics, which could have all kinds of biases and errors. I couldn’t find an actual peer-reviewed research paper to support the numbers and neither could Adam Jacobs the stats guy.

  • Flakka and bath salts

    David Bradley
    13 May 2015 | 12:56 am
    Alpha-PVP (α-pyrrolidinopentiophenone, alpha-PVP) is a synthetic stimulant of the cathinone class; the street drug – commonly known as flakka – is chemically similar to the illegal high MDPV (bath salts), but lacks the 3,4-methylenedioxy motif; the same difference that distinguishes methamphetamine (meth) from MDMA (ecstasy). Hype in the media have alluded to flakk leading to extreme violence, paranoid psychoses, compulsive nudity and “zombie-like” behaviour and worse. Now, researchers at The Scripps Research Institute in California have demonstrated that alpha-PVP…

  • Three reasons diets don’t work

    David Bradley
    5 May 2015 | 6:14 am
    Interesting interview in The Washington Post that corroborates what I’ve thought about all these special weightloss diet scams and con tricks made to sell books and supplements. Here are the salient points: When you are dieting, you actually become more likely to notice food…and it actually begins to look more appetizing and tempting and harder to resist. As you lose body fat, hormone levels changes, in particular concentrations of the hormones that help you feel full decrease, while hunger hormones increase. As you diet, your metabolism slows down so as to get the most out of the…

  • The CIA Is Shuttering a Secretive Climate Research Program? [Stoat]

    William M. Connolley
    23 May 2015 | 1:43 pm
    So gushes Mother Jones, adding the enticing word “exclusive” to the story. But – weirdly enough, for a confection of spying and science reporting, both of which are normally so reliable – this appears to be a bit garbled. Firstly, the “climate research programme” looks to be more like the CIA had allowed civilian scientists to access classified data—such as ocean temperature and tidal readings gathered by Navy submarines and topography data collected by spy satellites. So, not CIA research at all: just data sharing. And presumably not CIA data mostly; if…
  • OSHA gives DuPont a 50% discount on penalty for death of 4 workers [The Pump Handle]

    Celeste Monforton, DrPH, MPH
    23 May 2015 | 11:41 am
    Last week OSHA announced citations and proposed a $99,000 penalty against DuPont for safety violations related to the November 2014 incident that killed four employees at its LaPorte, TX chemical plant. Wade Baker, 60, Gibby Tisnado, 48, Robert Tisnado, 39, and Crystal Wise, 53 were asphyxiated by methyl mercaptan because of gross failures in DuPont’s systems to manage highly hazardous chemicals. OSHA’s proposed penalty stems from one repeat, nine serious, and one other-than-serious violation. What baffles me is why OSHA didn’t propose the $70,000 maximum for the repeat violation. OSHA…

  • The Hydrophobic Temperature Dependence of Amino Acids Directly Calculated from Protein Structures

    Erik van Dijk et al.
    22 May 2015 | 2:00 pm
    by Erik van Dijk, Arlo Hoogeveen, Sanne Abeln The hydrophobic effect is the main driving force in protein folding. One can estimate the relative strength of this hydrophobic effect for each amino acid by mining a large set of experimentally determined protein structures. However, the hydrophobic force is known to be strongly temperature dependent. This temperature dependence is thought to explain the denaturation of proteins at low temperatures. Here we investigate if it is possible to extract this temperature dependence directly from a large set of protein structures determined at different…

While a number of methods for 3D reconstruction of genomic models based on Hi-C data were proposed, most of the analyses in the field have been performed on different 3D representation forms (such as graphs). Here, we reproduce most of the previous results on the 3D genomic organization of the eukaryote Saccharomyces cerevisiae using analysis of 3D reconstructions. We show that many of these results can be reproduced in sparse reconstructions, generated from a small…

    21 May 2015 | 2:00 pm
    by Wiktor Młynarski In mammalian auditory cortex, sound source position is represented by a population of broadly tuned neurons whose firing is modulated by sounds located at all positions surrounding the animal. Peaks of their tuning curves are concentrated at lateral position, while their slopes are steepest at the interaural midline, allowing for the maximum localization accuracy in that area. These experimental observations contradict initial assumptions that the auditory space is represented as a topographic cortical map. It has been suggested that a “panoramic” code has evolved to…

    by Yeliz Yuva-Aydemir, Xia-Lian Xu, Ozkan Aydemir, Eduardo Gascon, Serkan Sayin, Wenke Zhou, Yang Hong, Fen-Biao Gao Intragenic microRNAs (miRNAs), located mostly in the introns of protein-coding genes, are often co-expressed with their host mRNAs. However, their functional interaction in development is largely unknown. Here we show that in Drosophila, miR-92a and miR-92b are embedded in the intron and 3’UTR of jigr1, respectively, and co-expressed with some jigr1 isoforms. miR-92a and miR-92b are highly expressed in neuroblasts of larval brain where Jigr1 expression is low.

    by Rana Mroue, Brian Huang, Steve Braunstein, Ari J. Firestone, Jean L. Nakamura Imprinted genes are expressed from only one parental allele and heterozygous loss involving the expressed allele is sufficient to produce complete loss of protein expression. Genetic alterations are common in tumorigenesis but the role of imprinted genes in this process is not well understood. In earlier work we mutagenized mice heterozygous for the Neurofibromatosis I tumor suppressor gene (NF1) to model radiotherapy-associated second malignant neoplasms that arise in irradiated NF1 patients.

It consists of a pair of centrioles surrounded by pericentriolar material. The centrosome, like DNA, duplicates exactly once per cell cycle. During interphase duplicated centrosomes remain closely linked by a proteinaceous linker. This centrosomal linker is composed of rootletin filaments that are anchored to the centrioles via the protein C-Nap1. At the onset of mitosis the linker is dissolved by Nek2A kinase to support the formation of the bipolar…

  • Vibrio cholerae Response Regulator VxrB Controls Colonization and Regulates the Type VI Secretion System

    Andrew T. Cheng et al.
    22 May 2015 | 2:00 pm
    by Andrew T. Cheng, Karen M. Ottemann, Fitnat H. Yildiz Two-component signal transduction systems (TCS) are used by bacteria to sense and respond to their environment. TCS are typically composed of a sensor histidine kinase (HK) and a response regulator (RR). The Vibrio cholerae genome encodes 52 RR, but the role of these RRs in V. cholerae pathogenesis is largely unknown. To identify RRs that control V. cholerae colonization, in-frame deletions of each RR were generated and the resulting mutants analyzed using an infant mouse intestine colonization assay. We found that 12 of the 52 RR were…

    by Filipe Carvalho, Magda L. Atilano, Rita Pombinho, Gonçalo Covas, Richard L. Gallo, Sérgio R. Filipe, Sandra Sousa, Didier Cabanes Listeria monocytogenes is an opportunistic Gram-positive bacterial pathogen responsible for listeriosis, a human foodborne disease. Its cell wall is densely decorated with wall teichoic acids (WTAs), a class of anionic glycopolymers that play key roles in bacterial physiology, including protection against the activity of antimicrobial peptides (AMPs). In other Gram-positive pathogens, WTA modification by amine-containing groups such as D-alanine was largely…

    by Caline G. Matar, Neil R. Anthony, Brigid M. O’Flaherty, Nathan T. Jacobs, Lalita Priyamvada, Christian R. Engwerda, Samuel H. Speck, Tracey J. Lamb Immunity to non-cerebral severe malaria is estimated to occur within 1-2 infections in areas of endemic transmission for Plasmodium falciparum. Yet, nearly 20% of infected children die annually as a result of severe malaria. Multiple risk factors are postulated to exacerbate malarial disease, one being co-infections with other pathogens. Children living in Sub-Saharan Africa are seropositive for Epstein Barr Virus (EBV) by the age of 6…

  • The Ovary of Tubifex tubifex (Clitellata, Naididae, Tubificinae) Is Composed of One, Huge Germ-Line Cyst that Is Enriched with Cytoskeletal Components

    Anna Z. Urbisz et al.
    22 May 2015 | 2:00 pm
    by Anna Z. Urbisz, Łukasz Chajec, Piotr Świątek Recent studies on the ovary organization and oogenesis in Tubificinae have revealed that their ovaries are small polarized structures that are composed of germ cells in subsequent stages of oogenesis that are associated with somatic cells. In syncytial cysts, as a rule, each germ cell is connected to the central cytoplasmic mass, the cytophore, via only one stable intercellular bridge (ring canal). In this paper we present detailed data about the composition of germ-line cysts in Tubifex tubifex with special emphasis on the occurrence and…

  • Competence of Cimex lectularius Bed Bugs for the Transmission of Bartonella quintana, the Agent of Trench Fever

    Hamza Leulmi et al.
    22 May 2015 | 2:00 pm
    by Hamza Leulmi, Idir Bitam, Jean Michel Berenger, Hubert Lepidi, Jean Marc Rolain, Lionel Almeras, Didier Raoult, Philippe Parola Background Bartonella quintana, the etiologic agent of trench fever and other human diseases, is transmitted by the feces of body lice. Recently, this bacterium has been detected in other arthropod families such as bed bugs, which begs the question of their involvement in B. quintana transmission. Although several infectious pathogens have been reported and are suggested to be transmitted by bed bugs, the evidence regarding their competence as vectors is unclear.

    22 May 2015 | 2:00 pm
    by Rebecca L. Renberg, Xiaojing Yuan, Tamika K. Samuel, Danilo C. Miguel, Iqbal Hamza, Norma W. Andrews, Andrew R. Flannery Leishmania spp. are trypanosomatid parasites that replicate intracellularly in macrophages, causing serious human morbidity and mortality throughout the world. Trypanosomatid protozoa cannot synthesize heme, so must acquire this essential cofactor from their environment. Earlier studies identified LHR1 as a Leishmania amazonensis transmembrane protein that mediates heme uptake. Null mutants of LHR1 are not viable and single knockout strains have reduced virulence, but…

    Twitter buddy Jeremy was lamenting the fact that the manufacturer of his new PC with its 1 terabyte hard drive was urging him to sign up for its cloud storage service. He suggested it was pointless with all those bytes to fill with his home stuff it was never going to be needed. I suggested that cloud storage gives him offsite backup of his files, but he suggested that made sense for businesses where mission-critical information might be lost, but he felt he’d have more to worry about if his house burned to the ground than his backup.

    22 May 2015 | 3:21 am
    If you read the books or watched the movies, you get the sense that Frodo and Sam walked pretty far to toss that ring in the fire. Imgur user mattsawizard compared the journey distance with some rough real-life geography. The journey was 1,350 miles, which is kind of like walking from Los Angeles, California to Austin, Texas. Or, from a European point of view, it'd be like a trip from London, England to Niš, Serbia. See the full trip breakdown. Tags: humor, Lord of the Rings

    Computers can calculate an infinite number of colors, but our brains can only process and see so much. This is why color spaces are important in visualization. Your code might dictate different shades, but they might look the same when you look at the visual. And it's why Scott Sievert explored the various spaces and provides an interactive for comparing various shades. We see that certain color spaces are constrained by device limitations (RGB, HED). We see that other color spaces emphasize the pigments (HSV) or other elements like additive/subtractive color (LUV, LAB). We see that certain…

The research was published in Science, but Donald Green asked the publication to retract the paper recently. It seems his co-author and UCLA graduate student, Michael LaCour, made up a lot of data. Green today told me if there was no survey data, what's incredible is that LaCour produced all sorts of conclusions and evaluations of data that didn't exist. For instance, he had "a finding comparing what…

    One day, when humans go to Mars, they might find that, occasionally, the Red Planet has green skies. NASA's MAVEN spacecraft has detected evidence of widespread auroras in Mars's northern hemisphere. Unlike Earth, Mars does not have a global magnetic field that envelops the entire planet. Instead, Mars has umbrella-shaped magnetic fields that sprout out of the ground like mushrooms, here and there, but mainly in the southern hemisphere. These umbrellas are remnants of an ancient global field that decayed billions of years ago.

    How climate drives bird migration Pine siskins, a species of seed-eating boreal bird, will spend some winters in the pine, spruce and fir forests of Canada, and then arrive at bird feeders much farther south during others. Ornithologists suspected the irregular migrations tracked oscillating climate patterns, but a direct link was elusive, until now. Pine Siskin photo by PutneyPics Why do certain birds suddenly leave their winter territory -- sometimes in the middle of winter? The more familiar, "seasonal" migration is triggered by changes in day length, and birds tend to fly south in winter.

    Squid, cuttlefish and octopuses are masters of camouflage, capable of changing their skin colors and patterns in the blink of an eye. Two new studies, published this week in the Journal of Experimental Biology, find that cephalopod skin is chock-full of light-sensing cells typically found in eyes that help them "see." The cells likely send signals to alter skin coloration without involving the central nervous system, the researchers said.

    The term ‘yellow fever’ is basically used to denote a viral infection that is largely spread by mosquitoes. Here’s a look into its symptoms, causes and treatment: The symptoms of yellow fever The one thing that needs to be mentioned here is that there are three stages of yellow fever. The stages have been categorized on the basis of intensity of symptoms. Discussed below are a few details regarding all three separate stages: Stage 1 – Infection The very first stage is that of infection. This particular stage is characterized by symptoms including loss of appetite, headache, fever,…

  • Who Invented Paper?

    theghostwriter
    5 Jul 2014 | 8:17 pm
    Paper, as we all know, is commonly used for various purposes including printing, wrapping and writing. These days, it is normal for paper to be prepared using wood that is acquired from rapidly growing tress like: Pine Fir Spruce Now when it comes to the invention of paper, the one thing that we know is that the very first paper was produced in 3500 BC. It was the ancient Egyptians who did so. what they basically did was that they took strips of papyrus reeds, dampened them and produced a more so criss-cross pattern that was later pressed into sheets. Believe it or not, but the word paper has…

  • Problems amplifying GC-rich regions? Problem Solved!

    Olwen Reina
    21 May 2015 | 2:00 am
    No, it isn’t you that’s the problem, and you’re certainly not alone if you’re having trouble amplifying GC-rich sequence and/or understanding why GC-rich sequences are causing such problems in the first place! Amplification of GC-rich sequences by PCR has been an irritant for scientists for decades! When we say “GC-rich” we mean ?60% of the bases are either cytosine (C) or guanine (G.) There are several options available, which alone or in combination may help you to deal with this problem, but first let’s look at why GC-rich sequences are more difficult to amplify. The Cause of…
  • The Art of Approval: Getting a New Protocol Approved by Your Institution

    Ellen DeGennaro
    20 May 2015 | 2:00 am
    All of your planning has paid off. You just got the green light from your PI to start work on a new experiment that you have been plotting for weeks, but it involves some new techniques that you’ll need to run past your institution’s scientific approval committee first. No problem, right? Not necessarily. While many may view this as yet another obstacle thrown in our way by evil bureaucrats that want to slow the pace of scientific progress, I promise you that there is nothing so sinister going on. Getting this kind of approval is a very important step in the modern scientific circle of…
  • Fast-track your Ampicillin Plasmid Transformations

    Nick Oswald
    19 May 2015 | 3:02 am
    Most of us use pretty standard transformation protocols for E.coli. Yours probably goes something like this: – Thaw the competent cells on ice – Add DNA – Electroporate (or incubate then heat shock for chemically competent cells) – Add rich medium (LB or SOC) – Incubate at 37°C (or appropriate temperature) for 30-60 minutes – Spread onto antibiotic plates That 30-60 minute incubation can be pretty annoying, especially if you are performing the transformation late in the day. The good news is that if you are using ampicillin as your selection antibiotic,…
  • Capillary Gel Electrophoresis: An Alternative to SDS-PAGE?

    Olwen Reina
    19 May 2015 | 2:00 am
    When you think about separating proteins, do you think about separating them using a gel? Specifically using SDS-PAGE? If you answered “yes”, it is for good reason. SDS-PAGE is ubiquitous in molecular biology labs because it is good at separating proteins. However, SDS-PAGE takes a lot of time and is labor-intensive. So let’s expand your toolbox and look at another way of separating proteins: Capillary gel electrophoresis. Capillary gel electrophoresis (CGE) a.k.a. capillary sieving electrophoresis a.k.a. SDS-capillary gel electrophoresis separates proteins in a gel via columns filled…
  • A Guide to Flow Cytometry Software: Becton Dickinson’s ‘Diva’

    Rachael Walker
    19 May 2015 | 2:00 am
    If you use a Becton Dickinson (BD) cytometer in your lab, the chances are you are acquiring your data using ‘Diva’ software. Diva software is used to acquire your cytometry data on LSRII, LSRFortessa, CantoII and Aria cell sorters. As well as acquiring your data using Diva software, you can also analyse your data after you have run your samples. However, Diva doesn’t have as many tools for post-acquisition analysis as programs such as FlowJo or FCSExpress. You can use it for simple post-acquisition analysis such as gating, simple statistics and creating plots for your figures. Over the…

    I’ve been entranced by sharks since I was a little kid. From the first time I saw Jaws, I was hooked (pun intended). There are so many aspects of a shark’s physiology I admire, but my favorite point of fascination is probably the variety of hunting techniques they use to capture their prey. Though most of my friends are aware of my sharktastic obsession, others are surprised because I’m, well, a vegetarian. Yes, I’m a vegetarian with an intense interest and, dare I say, admiration for this aquatic carnivore’s feeding habits. This animal’s intelligence, grace, stealth, and prowess…

    Allergies to natural latex affect about 3 million Americans. Life can be complicated for those people when they have to stay in hospitals where gloves, syringes, bandages, and intravenous tubes usually contain natural rubber. These folks also have to get creative with contraception; most condoms are also made from natural rubber.A protein named prohevein is the source of all this aggravation, and it’s found in the most common source of latex, the rubber tree (Hevea brasiliensis). While many synthetic alternatives have been developed and are in use today, none have entirely imitated natural…

Some people take the view that the universe is simply there and it runs along-it's a bit as though it just sort of computes, and we happen by accident to find ourselves in this thing. I don't think that's a very fruitful or helpful way of looking at the universe, I think that there is something much deeper about it, about its existence, which we have very little inkling of at the moment."

    The Holocene Climate Optimum was a period of global climate warming that occurred between six to nine thousand years ago. At that time, the global average temperatures were somewhere between four to six degrees Celsius higher than they are today. That is the range of warming that climatologists are predicting due to the build-up of greenhouse gases in the atmosphere from human activity. So information about the behavior of the monsoon during the Holocene could provide clues to how it is likely to behave in the future. This knowledge could be very important for the 600 million people living on…

    ADepartment of Chemistry, University of Toronto, 80 St. George Street, Toronto, ON, M5S 3H6, Canada BCloud Physics and Severe Weather Research Section, Environment Canada, 4905 Dufferin Street, Toronto, ON, M3H 5T4, Canada The Greater Toronto Area (GTA) is home to roughly 5.5 million people and is situated on the northwestern shore of Lake Ontario. The region is often afflicted with poor air quality during summer months as a result of high levels of ozone (O3) which is harmful to both humans and plants. O3 is formed from a series of complex chemical reactions involving nitrogen oxides (NOx,…
  • Lake Erie Algae Ups Asian Carp Vulnerability

    Daniel Kelly
    12 May 2015 | 6:37 am
    Using remote sensing technology, water temperatures and biological models, scientists at the U.S. Geological Survey have found that there is enough food for Asian carp to survive if they make it into Lake Erie, according to a release from the agency. The findings come after another study that found evidence of carp breeding near the Great Lake in 2013. Asian carp have a penchant for algae, so scientists zeroed in on the availability of that food source in Erie. Given the lake’s history of algal blooms since 2000, they found that there was plenty of slimy green stuff for carp to snack on.

    Greg Fish
    21 May 2015 | 7:56 am
    Hiring people is difficult, no question, and in few places is this more true than in IT because we decided to eschew certifications, don’t require licenses, and our field is so vast that we have to specialize in a way that makes it difficult to evaluate us in casual interviews. With a lawyer, you can see that he or she passed the bar and had good grades. With a doctor, you can see years of experience and a medical license. You don’t have to ask them technical questions because they obviously passed the basic requirements. But software engineers work in such a variety of…

    We’re using far too many antibiotics. That has been the cry from the FDA and the WHO for the last several years as more and more antibiotic-resistant strains have been found after they had colonized or killed patients. Of course these bacteria aren’t completely immune to our arsenals of drugs, they’re just harder to kill with certain antibiotics or require different ones, but a rather small, yet unsettling number, have required doctors to use every last antibacterial weapon they had available to even make a dent in their populations. There’s not much we can do because…

    A Type Ia supernova designated SN 2014J in the galaxy M82, captured by the Hubble Space Telescope. NASA, ESA, A. Goobar (Stockholm University), and the Hubble Heritage Team (STScI/AURA), CC BYWhen we look up at the night sky, it’s easy to feel as though the stars we see have always been, and always will be, there. But just like ourselves, stars are born and die. And when they die, they sometimes do not go gently but end their lives in supernovae – gigantic explosions that, at their brightest, outshine entire galaxies of stars. Supernovae bright enough to be seen with the unaided eye…
  • Social media sackings risk stifling journalistic expression

    Journalists are often expected to engage with social media. Esther Vargas/Flickr, CC BY-SAThe one defining ideal of journalism is the belief that journalists should “speak the truth” even when the truth may be contested, unpopular or damaging. The ideal of freedom of expression is the bedrock of journalism, hard won since “freedom of the press” meant being able to own and operate a printing press, free of government control and without a licence. For nearly 500 years journalists have maintained a significant degree of autonomy despite the constant tension with the editorial,…

Alex Cherney/MV, CC BY-NCSaturn is the most distant planet that can be seen with the naked eye and this weekend brings it closest to Earth for 2015. Seen as a small star, with a steady light and a slightly yellow-tinge, the planet is currently rising in the east as the sun sets in the west. In other words, Saturn is directly opposite the sun in the sky – what is known as opposition. The planet officially reaches opposition at 11:22am on Saturday morning, May 23 (AEST).

    The number of middle-aged men and women suffering a cerebral stroke has apparently risen significantly in the last decade or so. It seems that the press release from the Stroke Association making this pronouncement which has been widely reported almost verbatim by the media is based on NHS hospital admission statistics, which could have all kinds of biases and errors.

    Alpha-PVP (α-pyrrolidinopentiophenone, alpha-PVP) is a synthetic stimulant of the cathinone class; the street drug – commonly known as flakka – is chemically similar to the illegal high MDPV (bath salts), but lacks the 3,4-methylenedioxy motif; the same difference that distinguishes methamphetamine (meth) from MDMA (ecstasy). Hype in the media have alluded to flakk leading to extreme violence, paranoid psychoses, compulsive nudity and “zombie-like” behaviour and worse. Now, researchers at The Scripps Research Institute in California have demonstrated that alpha-PVP…

    5 May 2015 | 6:14 am
    Interesting interview in The Washington Post that corroborates what I’ve thought about all these special weightloss diet scams and con tricks made to sell books and supplements. Here are the salient points: When you are dieting, you actually become more likely to notice food…and it actually begins to look more appetizing and tempting and harder to resist. As you lose body fat, hormone levels changes, in particular concentrations of the hormones that help you feel full decrease, while hunger hormones increase. As you diet, your metabolism slows down so as to get the most out of the…

My favorite one depicted two scoops of ice cream with cherries on top, strategically set to look like breasts. The caption underneath suggested that exclusive breastfeeding for six months would lower a child’s risk of obesity. Presumably the implication was that if you chose to breastfeed, your child could later eat ice cream with impunity.It was a great visual, and given the current rate of obesity in the United States, a compelling…

    Often, in science fiction, it’s not easy to tell what came before: the science or the fiction. Many inventions appeared in the ink before they did in reality. The submarine, for example, surfaced in the 1870 Jules Verne classic, “Twenty Thousand Leagues Under the Sea,” much before it made it to our naval fleets. The fiction came before in this instance. Take now a book of our age. In “Singularity Sky,” published in 2005, Charles Stross describes the Lord Vanek, the flagship of the imperial space-navy of a future civilization called the New Republic, as a 90,000 tonne-warship,…

Or 100 calories from chocolate chip muffins would have meant the same as 100 calories coming off carrots. But our foods are a mix of so many different things that it is hard to keep a track of all the different calories you consumed. To keep a track of what goes in, the printed calorie count usually is enough, as long as you are making sure its good wholesome food you are eating. Restaurants these days are required to post calorie information adjacent to the mentioned food item in their…

    By Anupum Pant While animals are often tranquillized using tranquillizing darts, there’s no such reliable instrument for humans because of two main reasons: 1. The amount of dose has to be varied after the weight of the creature to be sedated is estimated. If the dose is far too less, there isn’t proper effect and if it is too much the animal would die. There’s no way of estimating the weight and changing the dose quickly enough to deal with humans of various sizes. 2. The tranquillizer has to go through the blood stream for it to take effect. So, it usually takes a couple…

  • Fiction: Yar’s Plume

    21 May 2015 | 9:02 am
    In the fiction piece Yar's Plume, the main character is too valuable to throw away, too dangerous to let be. It was uncomfortably chilly on the night we saw each other last. I remember the methane snow flakes and the carbon ice, the first time around. The landscape around the Plume had unusually eerie feeling. Even a really long displacement such as the one I was going through now could not approximate the feeling. The memory somehow made the hair on my back rise. A distant, logical and pedantic part of my troubled, aching mind sought to inform the other part – the instinctive,…

  • Dune: the Most Important Science Fiction Art Ever

    Jeff Love
    20 May 2015 | 6:28 am
    If there's anywhere the old axiom about judging a book by its cover holds true, it's science fiction. Few authors and the artists employed to visualize their stories achieve a real dialogue; more often than not, throughout the history of science fiction, literature of real depth is sold with flashy aliens and cosmic exaggerations. An extraordinary illustrator, however, is capable of contributing to a piece of literature just as meaningfully as its author. In the case of an artist like John Schoenherr, he becomes the work's joint architect–and leaves a mark no less indelible. Schoenherr's…

    When you do a simple Web search on a topic, the results that pop up aren't the whole story. The Internet contains a vast trove of information -- sometimes called the "Deep Web" -- that isn't indexed by search engines: information that would be useful for tracking criminals, terrorist activities, sex trafficking and the spread of diseases. Scientists could also use it to search for images and data from spacecraft. Subject:  Computer Science

    NASA's Curiosity Mars rover climbed a hill Thursday to approach an alternative site for investigating a geological boundary, after a comparable site proved hard to reach. The drive of about 72 feet (22 meters) up slopes as steep as 21 degrees brought Curiosity close to a target area where two distinctive types of bedrock meet. The rover science team wants to examine an outcrop that contains the contact between the pale rock unit the mission analyzed lower on Mount Sharp and a darker, bedded rock unit that the mission has not yet examined up close.

    One day, when humans go to Mars, they might find that, occasionally, the Red Planet has green skies. In late Dec. 2014, NASA's MAVEN spacecraft detected evidence of widespread auroras in Mars's northern hemisphere. The "Christmas Lights," as researchers called them, circled the globe and descended so close to the Martian equator that, if the lights had occurred on Earth, they would have been over places like Florida and Texas.

    Troy Oakes
    22 May 2015 | 3:30 am
    Stone tools made by our ancient ancestors have been dated to be around 3.3 million years old. Scientists have stated that this is a “new beginning to the known archaeological record.”  Scientists now believe that the dawn of culture has been pushed back by 700,000 years. This is a much earlier sign of human progress than previously known, and well before the first known member of our genus Homo.

    Researchers at Yale have answered a long debated question about which competing model of evolution works best. They have come up with the answer by using a sophisticated modeling of genomic data from diverse species. In their study, which was published in the journal Molecular Biology and Evolution, they suggest the “house of cards” model, which holds that mutations with large effects effectively reshuffle the genomic deck, explains evolutionary processes better than the theory that species undergo the accumulation of many mutations with small effects, wrote Yale News.

Just like the next homo sapien I get excited over fossils, but I’ll admit it, I geek out even more over plant  fossils.  Why?  Well a couple of reasons actually … 1) As plants are typically comprised of softer tissue, than bone, I am always amazed that the right conditions existed to allow for the fossil formation of plants, rather than them decomposing, and 2) As many of these plants still exist today, showing what incredibly resilient organisms they are.

  • When Whales Started to See the Ocean With Sound

    Brian Switek

    For dolphins and other toothed whales, the ocean is a vast soundscape. Even when they cannot visually see their surroundings, they can still picture what’s going on by sending out sound and listening to the image of the returns – echolocation. But when did whales gain this fantastic ability? A fossil skull described last year holds an important clue. Paleontologist Jonathan Geisler and colleagues named it Cotylocara macei –  a whale that swam the sea off South Carolina around 28 million years ago. The marine mammal wouldn’t have looked quite like a modern whale…

    Brian Switek
    27 Apr 2015 | 4:48 pm
    Reassembling a fossil skeleton is sometimes said to be like putting a puzzle together. It’s not an inaccurate analogy, but there are some significant differences. For example, you can never be totally sure what the animal is going to look like when you start. There’s no box to tell you what the end result should be. Sure, the basics of anatomy can help you differentiate between tooth, vertebra, femur, and other pieces, but if paleontologists don’t pay meticulous attention to all the parts, they might create a chimera of bones that don’t really fit together.

    Peer-review is essential to keep science on track. But it can be too demanding on scientists, who are asked to do it for free and anonymously. How many papers are fair to review or to decline? Not long ago, I asked a top-notch scientist how often he accepted papers to review. His answer was curious. He told me: “I publish 30 to 40 papers a year. Each one takes two or three reviewers, making about 100 reports. I feel that I have to give this same quantity of reports back to keep the system working. Therefore, I review about 100 papers a year.” I was a bit surprised. First by the…

    We are all well aware of the detrimental genetic consequences of inbreeding such as hemophilia, color blindness and many other genetic disorders especially amongst British and Russian monarchies, however the impact of marriage rules on genetic diversity has never been studied. Now a team of researchers led by Murray Cox, professor at Massey University, has examined the effects of arranged marriage on genetic diversity. This study is the first of its kind. Given the importance at the traditional culture of the Indonesian Rindi, which marriage rules dictate at a man ideally marries his first…
  • Fun Science Fact: Which Came First, The Chicken Or The Egg? It’s The Chicken And Here Is Why

    This age-old scientifically and philosophically challenging riddle: Which came first, the chicken or the egg? was first unshadowed by researchers at Sheffield and Warwick universities. According to the researchers, the protein which makes egg shells is only produced by chickens, so the egg can only exist if it has been created inside a chicken. Therefore, it’s the chicken that came first, not the egg. The post Fun Science Fact: Which Came First, The Chicken Or The Egg? It’s The Chicken And Here Is Why appeared first on Sparkonit.

    Last time, we wrote about introduction to genetics that explains certain facts about genes and how possibly the DNA made the life on earth possible; and also answers to: What makes us “us”? What is responsible for producing startling inherited resemblances between the members of a family as well as distinctive variations in different generations? Why are identical twins so ‘identical’? Why do some diseases tend to run in families? What causes diseases like cancer, diabetes, AIDS and Alzheimer’s so difficult to cure? How is production of clones possible? Well, here is another video…
  • Talking and Writing are Independent, See How Brain Separates Our Ability to Talk and Write

    Writing is a system of human visual communication that represents language using signs and symbols. The human ability to write evolved from our ability to speak and since it is an evolutionary human invention, its underlying principle cannot be determined by the genetic code. Now, a team of researchers at Johns Hopkins University have found that writing and talking are two independent systems that someone who can’t write a grammatically correct sentence may be able say it aloud flawlessly. For example, when someone says, “The man is catching a fish.” The same person then takes pen…

    We’ve considered an awful lot about what makes Orphan Black Wikia - Sarah Manning (Tatiana Maslany - IMDb Page), Orphan Black Wiki - Alison Hendrix, (Tatiana Maslany - IMDb Page), and the swelling multitude of clones in the Orphan Black universe so dang diverse. Essentially, each week we’ve asked the science questions on the minds... The post Can clones fall on different parts of the sexuality spectrum? appeared first on Science vs Hollywood.

    So far, this series on the science behind Orphan Black has made a number of conclusions, or should I say clone-clusions? To very briefly summarize: (1) it’s hard to make a synthetic genome; (2) it’s harder to make viable clones, even without first synthesizing their genomes; (3) clones can be wildly different from each other...

    Impact crater or supervolcano caldera?At first glance, the region covered by this latest Mars Express image release appears to be pockmarked with impact craters. But the largest structure among them may hold a rather explosive secret: it could be remains of an ancient supervolcano. The images presented here were taken by the high-resolution stereo camera on ESA’s Mars Express on 26 November 2014, and focus on the Siloe Patera feature in the Arabia Terra region of Mars. Siloe Patera comprises two large nested craters, close to the centre of the main colour image. The outer rim measures about…
