    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…

  • Depressed preschoolers still suffer years later

    Jim Dryden-WUSTL
    30 Jul 2014 | 8:40 am
    Children diagnosed with depression in preschool are 2.5 times more likely to have the condition in elementary and middle school, report researchers. “It’s the same old bad news about depression; it is a chronic and recurrent disorder,” says child psychiatrist Joan L. Luby, who directs Washington University’s Early Emotional Development Program. “But the good news is that if we can identify depression early, perhaps we have a window of opportunity to treat it more effectively and potentially change the trajectory of the illness so that it is less likely to be…
  • Can patients with cancer risk handle false positives?

    David Orenstein-Brown
    30 Jul 2014 | 8:36 am
    Many people who undergo preventative computerized tomography (CT) lung screenings receive positive results on the screening test, only to find out that they’re actually cancer-free. The US Preventive Services Task Force recently recommended this CT lung screening for people at high risk for cancer. Many policymakers have expressed concern that this high false-positive rate will cause patients to become needlessly upset. A new study of National Lung Screening Trial participant responses to false positive diagnoses, however, finds that those who received false positive screening…
  • Moms teach babies the smell of fear

    30 Jul 2014 | 7:50 am
    Anxious mother rats give off an odor that teaches their newborn babies to be afraid. Researchers studied mother rats who had learned to fear the smell of peppermint and saw them teach this fear to their babies in their first days of life by using an alarm odor that is released during distress. The scientists pinpointed the specific area of the brain where this fear transmission takes root in the earliest days of life. Their findings in animals may help explain a phenomenon that has puzzled mental health experts for generations: how a mother’s traumatic experience can affect her…

    A new study challenges the notion that minority students are less likely to complete their undergraduate degree if they attend minority-serving colleges and universities. Looking strictly at graduation statistics, historically black colleges and universities (HBCUs) lag about 7 percent below traditional institutions, and Hispanic-serving institutions (HSIs) trail by about 11 percent.

    A tamoxifen gel applied to the breast may work as well as a pill form of the drug to slow the growth of cancer cells. Because the drug is absorbed through the skin directly into breast tissue, less of it enters the blood, potentially minimizing dangerous side effects such as blood clots and uterine cancer.

    A systematic review and meta-analysis of randomized clinical trials on the effects of tree nuts for metabolic syndrome found a "modest decrease" in blood fats known as triglycerides and blood sugars compared to those who ate a control diet.   Tree nuts are such things as almonds, Brazil nuts, cashews, chestnuts, coconuts, hazelnuts, pecans, macadamia nuts, walnuts, pine nuts and pistachios and appear to help reduce two of the five markers for metabolic syndrome, a group of factors that raise the risk for heart disease and other health problems such as diabetes and strokes, a…

Taking folic acid before and during early pregnancy is linked to a reduction in the risk of neural tube defects like spina bifida. The current recommended dose is 400 ìg (micrograms) a day though it is unclear how much daily folic acid is needed to prevent neural tube defects. read more

  • Medicaid May Be Why So Many Mentally Ill People Are In Prison

    News Staff

    In the 1800s, mentally ill people were in jail. Then they were put in more humane mental hospitals. But then mental hospitals got vilified in mainstream news stories and horror movies and they were closed and now mentally ill people are back in jails, 10 times as many as are in mental health facilities. Policy makers don't buy that psychology has value any more, and they feel only slightly better about psychiatry. Scrutiny and abuse has led politicians to demand tighter Medicaid policies governing antipsychotic drugs and a new paper links those tighter policies to increased incarceration…

  • Finding Quantum Lines of Desire

    Washington University in St. Louis
    30 Jul 2014 | 11:00 am
    What paths do quantum particles, such as atoms or photons, follow through quantum state space? Kater Murch of Washington University in St. Louis has used an "artificial atom" to continuously and repeatedly record the paths through quantum state space. From the cobweb of a million paths, a most likely path between two quantum states emerged, much as social trails emerge as people round off corners or cut across lawns between buildings.

In a new paper featured this week on the cover of Nature, scientists have shown that it is possible to track these quantum trajectories and compare them to a recently developed theory for predicting the most likely path a system will take between two states.

    Bayle Shanks
    25 Jun 2014 | 1:01 am
    This paper hypothesizes that postsynaptic CaMKII (calcium/calmodulin-dependent protein kinase II) receives synaptic input and then interacts with via phosphorylation, suggesting that memories may be encoded in the microtubules in this way. They note that the size and shape of CaMKII appears to be just right to phosphorylate the hexagonal lattices of tubulin proteins in microtubules. The paper also can “demonstrate microtubule-associated protein logic gates, and show how patterns of phosphorylated tubulins in microtubules can control neuronal functions by triggering axonal firings,…

  • Technique named ‘clarity’ makes chunks of dead brain transparent, allowing fluorescent labeling

    Bayle Shanks

    This technique takes a dead brain and permeates it with a transparent hydrogel matrix to keep proteins and nucleic acids in place. Then it removes the lipids. I guess the lipids are all that makes the brain opaque. At this point the brain is transparent but maintains its original structure so you can still label the proteins and nucleic acids. http://www.hhmi.org/news/deisseroth20130410.html

We tend to think that we understand ourselves and then create technologies to take advantage of that new knowledge but it usually happens the other way round – we invent something new and then use that as a metaphor to explain the mind and brain. As history has moved on, the mind has been variously explained in terms of a wax tablets, a house with many rooms, pressures and fluids, phonograph…

This reflects a common belief in cognitive science that there is a ‘missing law’ to be discovered that will tell us how mind and brain are linked – but it is quite possible there just isn’t one to be discovered. Marcus, not arguing for the theory himself, describes it when he writes: What we are really looking for is a bridge, some way of connecting two separate scientific…

  • Mitosis Gives a Brief Window of Opportunity for a Change in Gene Transcription

    Richard P. Halley-Stott et al.
    29 Jul 2014 | 2:00 pm
    by Richard P. Halley-Stott, Jerome Jullien, Vincent Pasque, John Gurdon Cell differentiation is remarkably stable but can be reversed by somatic cell nuclear transfer, cell fusion, and iPS. Nuclear transfer to amphibian oocytes provides a special opportunity to test transcriptional reprogramming without cell division. We show here that, after nuclear transfer to amphibian oocytes, mitotic chromatin is reprogrammed up to 100 times faster than interphase nuclei. We find that, as cells traverse mitosis, their genes pass through a temporary phase of unusually high responsiveness to oocyte…
  • Intense Sperm-Mediated Sexual Conflict Promotes Reproductive Isolation in Caenorhabditis Nematodes

    Janice J. Ting et al.
    29 Jul 2014 | 2:00 pm
    by Janice J. Ting, Gavin C. Woodruff, Gemma Leung, Na-Ra Shin, Asher D. Cutter, Eric S. Haag Conflict between the sexes over reproductive interests can drive rapid evolution of reproductive traits and promote speciation. Here we show that inter-species mating between Caenorhabditis nematodes sterilizes maternal individuals. The principal effectors of male-induced harm are sperm cells, which induce sterility and shorten lifespan by displacing conspecific sperm, invading the ovary, and sometimes breaching the gonad to infiltrate other tissues. This sperm-mediated harm is pervasive across…
  • Rogue Sperm Indicate Sexually Antagonistic Coevolution in Nematodes

    Ronald E. Ellis et al.
    29 Jul 2014 | 2:00 pm
    by Ronald E. Ellis, Lukas Schärer Intense reproductive competition often continues long after animals finish mating. In many species, sperm from one male compete with those from others to find and fertilize oocytes. Since this competition occurs inside the female reproductive tract, she often influences the outcome through physical or chemical factors, leading to cryptic female choice. Finally, traits that help males compete with each other are sometimes harmful to females, and female countermeasures may thwart the interests of males, which can lead to an arms race between the sexes known as…
  • Natural Selection on Individual Variation in Tolerance of Gastrointestinal Nematode Infection

    by Adam D. Hayward, Daniel H. Nussey, Alastair J. Wilson, Camillo Berenos, Jill G. Pilkington, Kathryn A. Watt, Josephine M. Pemberton, Andrea L. Graham Hosts may mitigate the impact of parasites by two broad strategies: resistance, which limits parasite burden, and tolerance, which limits the fitness or health cost of increasing parasite burden. The degree and causes of variation in both resistance and tolerance are expected to influence host–parasite evolutionary and epidemiological dynamics and inform disease management, yet very little empirical work has addressed tolerance in wild…
  • Codon-by-Codon Modulation of Translational Speed and Accuracy Via mRNA Folding

    Jian-Rong Yang et al.
    22 Jul 2014 | 2:00 pm
    by Jian-Rong Yang, Xiaoshu Chen, Jianzhi Zhang Rapid cell growth demands fast protein translational elongation to alleviate ribosome shortage. However, speedy elongation undermines translational accuracy because of a mechanistic tradeoff. Here we provide genomic evidence in budding yeast and mouse embryonic stem cells that the efficiency–accuracy conflict is alleviated by slowing down the elongation at structurally or functionally important residues to ensure their translational accuracies while sacrificing the accuracy for speed at other residues. Our computational analysis in yeast with…

  • Membrane Interaction of Bound Ligands Contributes to the Negative Binding Cooperativity of the EGF Receptor

    Anton Arkhipov et al.
    24 Jul 2014 | 2:00 pm
    by Anton Arkhipov, Yibing Shan, Eric T. Kim, David E. Shaw The epidermal growth factor receptor (EGFR) plays a key role in regulating cell proliferation, migration, and differentiation, and aberrant EGFR signaling is implicated in a variety of cancers. EGFR signaling is triggered by extracellular ligand binding, which promotes EGFR dimerization and activation. Ligand-binding measurements are consistent with a negatively cooperative model in which the ligand-binding affinity at either binding site in an EGFR dimer is weaker when the other site is occupied by a ligand. This cooperativity is…

  • From Spontaneous Motor Activity to Coordinated Behaviour: A Developmental Model

    Hugo Gravato Marques et al.
    24 Jul 2014 | 2:00 pm
    by Hugo Gravato Marques, Arjun Bharadwaj, Fumiya Iida In mammals, the developmental path that links the primary behaviours observed during foetal stages to the full fledged behaviours observed in adults is still beyond our understanding. Often theories of motor control try to deal with the process of incremental learning in an abstract and modular way without establishing any correspondence with the mammalian developmental stages. In this paper, we propose a computational model that links three distinct behaviours which appear at three different stages of development. In order of appearance,…
  • Analysis of Stop-Gain and Frameshift Variants in Human Innate Immunity Genes

    by Antonio Rausell, Pejman Mohammadi, Paul J. McLaren, Istvan Bartha, Ioannis Xenarios, Jacques Fellay, Amalio Telenti Loss-of-function variants in innate immunity genes are associated with Mendelian disorders in the form of primary immunodeficiencies. Recent resequencing projects report that stop-gains and frameshifts are collectively prevalent in humans and could be responsible for some of the inter-individual variability in innate immune response. Current computational approaches evaluating loss-of-function in genes carrying these variants rely on gene-level characteristics such as…

    by Alessandro Attanasi, Andrea Cavagna, Lorenzo Del Castello, Irene Giardina, Stefania Melillo, Leonardo Parisi, Oliver Pohl, Bruno Rossaro, Edward Shen, Edmondo Silvestri, Massimiliano Viale Collective behaviour is a widespread phenomenon in biology, cutting through a huge span of scales, from cell colonies up to bird flocks and fish schools. The most prominent trait of collective behaviour is the emergence of global order: individuals synchronize their states, giving the stunning impression that the group behaves as one. In many biological systems, though, it is unclear whether global order…

    by Kun Wang, Teng Sun, Na Li, Yin Wang, Jian-Xun Wang, Lu-Yu Zhou, Bo Long, Cui-Yun Liu, Fang Liu, Pei-Feng Li Long noncoding RNAs (lncRNAs) are emerging as new players in gene regulation, but whether lncRNAs operate in the processing of miRNA primary transcript is unclear. Also, whether lncRNAs are involved in the regulation of the mitochondrial network remains to be elucidated. Here, we report that a long noncoding RNA, named mitochondrial dynamic related lncRNA (MDRL), affects the processing of miR-484 primary transcript in nucleus and regulates the mitochondrial network by targeting…
  • An Intronic microRNA Links Rb/E2F and EGFR Signaling

    by Mary Truscott, Abul B. M. M. K. Islam, James Lightfoot, Núria López-Bigas, Maxim V. Frolov The importance of microRNAs in the regulation of various aspects of biology and disease is well recognized. However, what remains largely unappreciated is that a significant number of miRNAs are embedded within and are often co-expressed with protein-coding host genes. Such a configuration raises the possibility of a functional interaction between a miRNA and the gene it resides in. This is exemplified by the Drosophila melanogaster dE2f1 gene that harbors two miRNAs, mir-11 and mir-998, within its…
  • An ARID Domain-Containing Protein within Nuclear Bodies Is Required for Sperm Cell Formation in Arabidopsis thaliana

    Binglian Zheng et al.
    24 Jul 2014 | 2:00 pm
    by Binglian Zheng, Hui He, Yanhua Zheng, Wenye Wu, Sheila McCormick In plants, each male meiotic product undergoes mitosis, and then one of the resulting cells divides again, yielding a three-celled pollen grain comprised of a vegetative cell and two sperm cells. Several genes have been found to act in this process, and DUO1 (DUO POLLEN 1), a transcription factor, plays a key role in sperm cell formation by activating expression of several germline genes. But how DUO1 itself is activated and how sperm cell formation is initiated remain unknown. To expand our understanding of sperm cell…

    by Jian-Rong Yang, Shuxiang Ruan, Jianzhi Zhang All forms of life are confronted with environmental and genetic perturbations, making phenotypic robustness an important characteristic of life. Although development has long been viewed as a key component of phenotypic robustness, the underlying mechanism is unclear. Here we report that the determinative developmental cell lineages of two protostomes and one deuterostome are structured such that the resulting cellular compositions of the organisms are only modestly affected by cell deaths. Several features of the cell lineages, including their…

  • Antibody to gp41 MPER Alters Functional Properties of HIV-1 Env without Complete Neutralization

    Arthur S. Kim et al.
    24 Jul 2014 | 2:00 pm
    by Arthur S. Kim, Daniel P. Leaman, Michael B. Zwick Human antibody 10E8 targets the conserved membrane proximal external region (MPER) of envelope glycoprotein (Env) subunit gp41 and neutralizes HIV-1 with exceptional potency. Remarkably, HIV-1 containing mutations that reportedly knockout 10E8 binding to linear MPER peptides are partially neutralized by 10E8, producing a local plateau in the dose response curve. Here, we found that virus partially neutralized by 10E8 becomes significantly less neutralization sensitive to various MPER antibodies and to soluble CD4 while becoming…
  • The Semen Microbiome and Its Relationship with Local Immunology and Viral Load in HIV Infection

Contente-Cuomo, Erika Benko, Maliha Aziz, Lance B. Price, Rupert Kaul Semen is a major vector for HIV transmission, but the semen HIV RNA viral load (VL) only correlates moderately with the blood VL. Viral shedding can be enhanced by genital infections and associated inflammation, but it can also occur in the absence of classical pathogens. Thus, we hypothesized that a dysregulated semen microbiome correlates with local HIV shedding. We analyzed…
  • Lytic Gene Expression Is Frequent in HSV-1 Latent Infection and Correlates with the Engagement of a Cell-Intrinsic Transcriptional Response

    by Joel Z. Ma, Tiffany A. Russell, Tim Spelman, Francis R. Carbone, David C. Tscharke Herpes simplex viruses (HSV) are significant human pathogens that provide one of the best-described examples of viral latency and reactivation. HSV latency occurs in sensory neurons, being characterized by the absence of virus replication and only fragmentary evidence of protein production. In mouse models, HSV latency is especially stable but the detection of some lytic gene transcription and the ongoing presence of activated immune cells in latent ganglia have been used to suggest that this state is not…

Parthun Background Hif1p is an H3/H4-specific histone chaperone that associates with the nuclear form of the Hat1p/Hat2p complex (NuB4 complex) in the yeast Saccharomyces cerevisiae. While not capable of depositing histones onto DNA on its own, Hif1p can act in conjunction with a yeast cytosolic extract to assemble nucleosomes onto a relaxed circular plasmid. Results To identify the factor(s) that function with Hif1p to carry out chromatin assembly, multiple steps of column chromatography were carried out to fractionate the yeast cytosolic extract.

    A spot survey of non-techie friends suggests to me that a lot of people know that they should be concerned about the privacy of their data, but generally are not worried that Google or many other search engines are tracking them. The privacy issue only comes to light when their newspaper mentions Heartbleed, Facebook’s settings changing and getting a mention in the mainstream media or when Snowden and the NSA are suddenly back on the tabloid agenda. And, of course, if one of the sites they use gets hacked, then that suddenly brings the security and privacy issues to the fore. Search…

    In 2010, I surveyed visual explorations of traffic, and it was all about how cars, planes, trains, and ships moved about their respective landscapes. It was implied that the moving things had people in them, but the focus was mostly on the things themselves. Location data was a byproduct of the need of vehicles to get from point A to point B in the most efficient way possible. Airplanes floated across the sky. Cabs left ghostly trails in the city. The visualization projects were, and still are, impressive. However, around the same time, it was growing more common for people to carry phones…

    The first ever example of a plant-eating dinosaur with feathers and scales has been discovered in Russia. Previously only flesh-eating dinosaurs were known to have had feathers, so this new find raises the possibility that all dinosaurs could have been feathered.
  • Acupuncture provides significant quality of life improvements among breast cancer patients taking drugs to prevent recurrence, study shows

    30 Jul 2014 | 1:34 am
    Use of electroacupuncture (EA) – a form of acupuncture where a small electric current is passed between pairs of acupuncture needles – produces significant improvements in fatigue, anxiety and depression in as little as eight weeks for early stage breast cancer patients experiencing joint pain related to the use of aromatase inhibitors (AIs) to treat breast cancer. The study is the first demonstration of EA’s efficacy for both joint pain relief, as well as these other common symptoms.

Does aeronautical engineering respond to the same basic physics that governs bird evolution? Photo: Boeing Evolution through natural selection governs the “design” of flying creatures. Engineers design flying machines. But flying is about physics, and physics is the ultimate arbiter of both processes, says Adrian Bejan, a professor of mechanical engineering at Duke University.

    Amphibian decline: Frogs fight back! In the worldwide extinction crisis, the most depressing stories concern amphibians — four-legged animals like frogs and salamanders that undergo metamorphosis to reach their adult form. The International Union for the Conservation of Nature says about 30 percent of the 6,285 amphibian species are threatened with extinction. A Cuban tree frog acquired immunological resistance to the deadly amphibian chytrid fungus during a study just published in Nature.

    Seeing fresh dust at a young supernova: Source of the planets? Supernova SN 2010jl exploded 150 million years ago, sending light carrying clues to the formation of cosmic dust, the building blocks of planets. Photo: European Southern Observatory Dust: It’s the bane of astronomers — since it blocks many wavelengths of light, dimming our view of the universe. But it’s also the source of planets. And that helps explain the excitement about the discovery of masses of dust created within months after a supernova was detected in 2010. By “dust,” astronomers mean tiny…

    The shape of the moon deviates from a simple sphere in ways that scientists have struggled to explain. A new study by researchers at UC Santa Cruz shows that most of the moon's overall shape can be explained by taking into account tidal effects acting early in the moon's history.

    As a quantum state collapses from a quantum superposition to a classical state or a different superposition, it will follow a path known as a quantum trajectory. For each start and end state there is an optimal or "most likely" path, but it is not as easy to predict the path or track it experimentally as a straight-line between two points would be in our everyday, classical world.

  • Scientists Closing in on Theory of Consciousness

    30 Jul 2014 | 10:15 am
    The 17th century French philosopher René Descartes proposed the notion of "cogito ergo sum" ("I think, therefore I am"), the idea that the mere act of thinking about one's existence proves there is someone there to do the thinking. "The only thing you know is, 'I am conscious.' Any theory has to start with that," said Christof Koch, a neuroscientist and the chief scientific officer at the Allen Institute for Neuroscience in Seattle. In the last few decades, neuroscientists have begun to attack the problem of understanding consciousness from an evidence-based perspective. In fact, Koch and…

    "What is the origin of that asymmetry?" study lead author Ian Garrick-Bethell, of the University of California, Santa Cruz, said. The newborn moon was thus primed to be sculpted by Earth's gravity, and that's exactly what happened, researchers say. Indeed, scientists have posited for more than a century that tidal forces helped shape the molten moon, causing bulges that froze into place when Earth's natural satellite cooled down and solidified. For example, tidal forces pulled on the lunar crust, stretching it out and heating it up in places.

    Asteroids and comets that repeatedly smashed into the early Earth covered the planet's surface with molten rock during its earliest days, but still may have left oases of water that could have supported the evolution of life, scientists say. Although this time amounts to more than 10 percent of Earth's history, little is known about it, since few rocks are known that are older than 3.8 billion years old. "It was thought that because of these asteroids and comets flying around colliding with Earth, conditions on early Earth may have been hellish," said lead study author…

    Another study adds that marriages in which the wife has more education than her husband no longer have a higher risk of divorce than other marriages. What harmed marriages two decades ago may help them today, when couples and society have updated expectations. Julie Brines, a sociologist at the University of Washington, and colleagues caused a stir last year with a study that found that men who did traditionally feminine household chores (cleaning, cooking and laundry) had less sex in their marriages than men who stuck to "manly" activities, such as mowing the lawn.

    Much of Asia, Africa, and Latin America suffers from overhunting. Lambir Hills National Park in western Borneo, one of the most diverse forests in the world, is a key case study in how the forest fares when it loses the herbivores that once thinned saplings and the fruit eaters that dispersed seeds. At Lambir, saplings became more crowded, raising the risk that the plants would get sick, and the number of species has fallen. Some officials and activists are trying to stop overhunting and illegal trade of wildlife. If hunting can be controlled in the parks, researchers hope, large animals may…

    Before anything else, it is necessary for us to define what test tubes we are talking about. This is because there are different elements associated with the term ‘test tube’. First of all, there are scientific or glass test tubes, whereas the same term is used to denote babies that are born through a procedure called in-vitro fertilization, or test tube babies. Here, the term test tube is being used to denote the test tubes that are typically used in scientific labs. Now, test tubes are also known as sample tubes, or culture tubes. These are actually a rather common piece of laboratory…

    The thing that was most difficult for me as an R beginner was plotting graphs with error bars – there is no concise way to do this with base graphics. There are workarounds, often using the ‘arrows’ command, but isn’t there a simpler way? Yes, in fact there are a handful of plotting packages for R: the two leaders being ggplot2 and lattice. Both have their advantages and disadvantages; one advantage of ggplot2 is that it seems to be more widely used and as a result there is more documentation available for it on the net. This tutorial will therefore use ggplot2. What you’ll learn:…

    More than a pun on the explosive growth of sequencing data, BLAST makes annotation and comparisons of similar sequences much easier. Created by a group at the U.S. National Center for Biotechnology Information in 1991, the Basic Local Alignment Search Tool is arguably the most heavily used tool for sequence analysis (that’s available for free, anyway). BLAST is a powerful and popular tool because it can find similarities between experimental and reference sequences (or a whole series of sequences) very quickly and accurately. There are several different types of BLAST algorithms, accessing…

    Good news lab workers! Always hated the tedious work of designing a cloning strategy? Or maybe always dreamed of pooling all the reactions in one tube, just to save time? Thanks to Mother Nature, and her wonderful type IIS endonucleases, this is now possible! What is this wonderful enzyme? Type II enzymes are one of the 4 (I-IV) types of recognized endonucleases (enzymes that cut DNA at a particular recognition site). Type II enzymes cleave within or a short distance from their recognition sites (usually 4–8 nucleotides in length.) They are the better known of all endonucleases and most…

For example, one popular frame considers love as perfect unity; in another frame, love is a journey. These two ways of thinking about relationships are particularly interesting because, according to a new study, they have the power to highlight or downplay the damaging effect of conflicts on relationship evaluation.

There is however, lots of evidence that they are breeding a new generation of “superbugs” – pathogens which develop resistance to drugs. Basically, reckless use of antibacterial substances and antibiotics is “training” pathogens, which become more and more dangerous. But that might change in the near future.

Too many people were being sickened and killed by bacterial endotoxin—a substance in a bacteria’s outer membrane toxic to animals and resistant to heat—contracted through vaccines and surgery tools. The only way to determine if something was contaminated was to test it on animals, a slow and expensive process. In 1956 a scientist named Fred Bang was studying the blood circulation in horseshoe crabs. He observed that when a crab became infected with gram-negative bacteria (a type of bacteria difficult to detect…

  • Real Teens Ask: What Are the Different Types of Opioids?

    Sara Bellum
    16 Jul 2014 | 6:16 am
    Learn more about the different types of opioids in this updated post from 2013. During the 2013 Drug Facts Chat Day, teens from across the country submitted their questions about drug abuse to NIDA scientists. A teen from Walter Johnson High School in Maryland asked: “What types of opioids are there?” Opioids are psychoactive chemicals that occur naturally (in the resin of the poppy plant) or can be made in a laboratory. They work by binding to opioid receptors in the central and peripheral nervous system and the gastrointestinal tract. There are illegal opioids (like heroin) as well as…
  • E-Cig Popularity on the Rise

    9 Jul 2014 | 7:54 am
    As states continue to pass laws that restrict the sale of e-cigarettes to minors, this post from 2013 explores why they've become so popular with teens. Good news! Cigarette smoking among American teenagers dropped to a record low in 2012. Not so good news—Many teens are turning to a new alternative known as “e-cigarettes.” What Are E-Cigarettes? Electronic cigarettes (e-cigs) are battery-operated products designed to deliver nicotine, flavor, and other chemicals as vapor that a user inhales, without producing actual tobacco smoke. A survey conducted by the Centers for Disease Control…

Every year, NIDA’s top scientists answer questions from teens at schools across the country during Drug Facts Chat Day. In 2010, “I AM MIKE” from Jefferson Township High School in Trenton, New Jersey asked: Are you more likely to do drugs if someone in your family does? The short answer is Yes. The risk for developing drug and alcohol problems is higher in children whose parents abuse alcohol or drugs—but it is NOT a…

    This post from 2012 gets a refresh highlighting new caffeine trends. Question: What’s the most widely used drug? It’s not marijuana—and no, it’s not tobacco or alcohol either. Nine out of 10 Americans take it in some form every day, and it’s not limited to adults. Hint: According to a recent study published by the American Academy of Pediatrics, nearly three-fourths (75%) of children, teens, and young adults use it daily too—in the form of soda, coffee, and energy drinks. Answer: Caffeine! That’s right, caffeine is a drug—a stimulant drug, to be exact. It’s even possible to…

    Friends can influence your opinion about music, fashion—and alcohol. In this updated post from 2013, NIDA provides strategies for staying true to yourself and avoiding peer pressure. Have you ever said “It’s not me, it’s my friends?” Turns out, this reasoning may not fly since what your friends do can have a big impact on you. Research studies show that teens whose best friends drink alcohol are twice as likely to try alcohol themselves. And, if teens get alcohol from friends, they’re more likely to start drinking at a younger age. It’s a big deal. We know that a person who…

  • Antarctic ice sheet is result of CO2 decrease, not continental breakup

    29 Jul 2014 | 9:00 pm
    Climate modelers from the University of New Hampshire have shown that the most likely explanation for the initiation of Antarctic glaciation during a major climate shift 34 million years ago was decreased carbon dioxide levels. The finding counters a 40-year-old theory suggesting massive rearrangements of Earth's continents caused global cooling and the abrupt formation of the Antarctic ice sheet. It will provide scientists insight into the climate change implications of current rising global CO2 levels.

    The Milky Way is smaller than astronomers previously thought, according to new research. For the first time, scientists have been able to precisely measure the mass of the galaxy that contains our solar system. Researchers have found that the Milky Way is approximately half the weight of ou neighboring galaxy – Andromeda – which has a similar structure to our own. The Milky Way and Andromeda are the two largest in a region of galaxies which astronomers call the Local Group. In this new study, researchers were also able to work out the mass of invisible matter found in the outer regions of…

      Astronomers have long known that interstellar molecules containing carbon atoms exist and that by their nature they will absorb light shining on them from stars and other luminous bodies. Because of this, a number of scientists have previously proposed that some type of interstellar molecules are the source of diffuse interstellar bands -- the hundreds of dark absorption lines seen in color spectrograms taken from Earth. In showing nothing, these dark bands reveal everything. The missing colors correspond to photons of given wavelengths that were absorbed as they travelled through the…
  • Mercury's Bizarre Magnetic Field --"Powered by Liquid Iron"

    Earth and Mercury are both rocky planets with iron cores, but Mercury's interior differs from Earth's in a way that explains why the planet has such a bizarre magnetic field, UCLA planetary physicists and colleagues report. Measurements from NASA's Messenger spacecraft have revealed that Mercury's magnetic field is approximately three times stronger at its northern hemisphere than its southern one. In the current research, scientists have created a model to show how the dynamics of Mercury's core contribute to this unusual phenomenon. Mercury's peculiar magnetic field provides evidence that…
  • Image of the Day --Planetary Disks in Weird Orbits Around their Host Stars

    dailygalaxy.com
    30 Jul 2014 | 4:00 am
    Unlike our solitary Sun, most stars form in binary pairs -- two stars that orbit a common center of mass. Though remarkably plentiful, binaries pose a number of questions, including how and where planets form in such complex environments. Stars and planets form out of vast clouds of dust and gas. As material in these clouds contracts under gravity, it begins to rotate until most of the dust and gas falls into a flattened protoplanetary disk swirling around a growing central protostar. Despite forming from a flat, regular disk, planets can end up in highly eccentric orbits, and may be…

    Anyone who has worked in a lab for more than a month understands that with the great excitement of research also comes frustration. This is part of the process of working at the forefront of knowledge–some ideas are going to work and some aren’t. As scientists, our job is to make advances in our understanding of the world around us and that doesn’t always come easily. However, we understand (first hand!) the toll that failed experiments can have on our attitude, motivation, and general outlook on career prospects. But if “understanding our experiments” is a…

    I recently picked up 1001 Video Games You Must Play Before You Die. I couldn't resist the title, which so neatly refracts the gibbering cultural anxieties of lists like "1000 novels everyone must read". You see this sort of highbrow listicle often in the realms of literary fiction, movies, possibly poetry. It's classic canon panic, and I say that with a degree of charity and warmth; I actually think arguing heatedly and even snobbishly about what works of art are important and mindbending can be a lot of fun, and occasionally useful to the parties involved. But there's something hilarious and…

It's considered one of the first big essays to tout the idea that "originals" -- writers of deep originality -- are more important and awesome than derivative folks. I heard about Conjectures while reading a different essay this evening, and since I'm sort of obsessed with tracking the rise of our modern (and disastrous) conceit that originality is something that just kind of wells up from inside you I immediately dialed up Conjectures on…

I'd always assumed, naively, that the crawl was done with computer graphics, but no: It was a steampunk affair, with the text printed on a piece of glass and filmed at a steep angle by a camera. But what really struck me was the quote from George Lucas about the formal properties of a crawl: "The crawl is such a hard thing because you have to be careful that you're not using too many words that people don't understand," Lucas has said.

  • Research Summary: Shading as a Control Method for Invasive European Frogbit

    Daniel Kelly
    30 Jul 2014 | 5:53 am
    European frogbit (Hydrocharis morsus-ranae L.) is an invasive floating plant in North American water bodies. The species escaped in 1939 from a Botanical Garden in Ottawa, Canada and had reached the United States by 1974. Studies have shown that light is essential for the germination and growth of European frogbit, that light-deprivation may reduce frogbit root growth by 90%. It follows that control methods utilizing shading are likely to inhibit the growth and spread of this invasive species. Shading has already been successfully used for controlling aquatic plants such as submerged cabomba.

    In May 2014, the government of Manitoba was making plans to treat invasive zebra mussels in Lake Winnipeg with potash, a type of fertilizer. Officials didn’t know if the idea would work, but were willing to try given the lake’s losing battle with the invasive. Plans called for four harbors in Lake Winnipeg to be sectioned off and then flooded with the liquid fertilizer. There was plenty of speculation if the treatment would kill off zebra mussels at all, as few studies gave concrete evidence of it working elsewhere. Victoria Beach, Lake Winnipeg.

    An Israeli Iron Dome missile is fired to intercept a rocket from Gaza.EPA/Abir SultanThe breakdown of an initial ceasefire between Israeli forces and Hamas last weekend played out to a familiar soundtrack: the wail of air-raid sirens and the menacing hiss of incoming rocket fire, followed in many cases by the concussive crackle of Iron Dome missiles intercepting their targets. The Iron Dome anti-missile system first attracted attention two years ago, when it achieved between an 80-90% success rate. But the sudden escalation of rocket attacks from Gaza in recent weeks, coupled with the success…

Designing a better plant has always been part of agriculture, but as we’ve learned more about genetics, our toolkit for developing those plants has expanded.

    A new self-assembling nanoparticle which targets cancerous tumours could boost the effectiveness of MRI scanning to help doctors diagnose the disease earlier. The iron oxide nanoparticles (IONPs), developed at Imperial College London, are designed to selectively undergo copper-free click conjugation upon sensing matrix metalloproteinase (MMP) enzymes. In this chemical reaction, the nanoparticles interact with the cell, shed their special protein coating and ‘click’ together to form a superparamagnetic nanocluster network capable of being seen on the scan. “By improving the sensitivity…

    What are eukaryotes? These are organisms whose cell structure such as organelles is enclosed within the membrane. The nucleus is the defining cell structure that sets eukaryotic cells apart from the prokaryotic cells. The presence of the nucleus gives these organisms their names. Being more complex than Prokaryotes, they make up all fungi, plant, animals such as amoeba. Eukaryotic cells are known for their strong cytoskeleton and their internal membranes. The cytoskeleton is made of proteins like actin and keratin which holds a cell together, differentiating its organelles. Eukaryote means…

    Introduction Prokaryotes are singled celled organisms and may be referred to as the earliest form of the most primitive life on earth. They include bacterial, prokaryotes and Achaeans. They are able to survive in a variety of environments including extreme habitats like swamps, hot springs, wet lands and the guts of animals. Prokaryotic cells are less complex when compared to eukaryotic cells. They lack a true nucleus and no DNA molecules. The following can be found in the bacterial cell: Capsule, Cell wall, cytoplasm, Plasma Membrane, Pili, Flagella, Ribosomes, Plasmids and the Nucleoid…

    Earlier this year, The Journal of the American Medical Association (JAMA) published a study on how women’s weight before getting pregnant affects their pregnancies. The paper argued that excess weight during pregnancy was associated with large increases in miscarriage and stillbirth. The fact that obesity raises many pregnancy risks — including fetal death — is generally well known. What made this paper striking, however, was that it suggested that the risks increase at much lower weights than previously thought: Based on the authors’ conclusions, you’re better off…

Another option is to give them discretion (e.g. look carefully at the fruit after three days, but use your judgment when it comes to deciding what to throw away). The tradeoffs are clear: The rule approach means you’ll lose more fruit, but the discretion approach means there will sometimes be rotting fruit in the mix if your employees don’t do a good…

The vast reaches of empty space between galaxies are bridged by tendrils of hydrogen and helium, which can be used as a precise “light meter.” In a recent study published in The Astrophysical Journal Letters, a team of scientists finds that the light from known populations of galaxies and quasars is not nearly enough to explain observations of intergalactic hydrogen. The difference is a stunning 400 percent. “It’s as if you’re in a big,…

  • A Man-Made Leaf

    Anupum Pant
    29 Jul 2014 | 10:35 am
    By Anupum Pant Julian Melchiorri, a graduate student from Royal College of art, claims to have fabricated the first ever man-made biological leaf which absorbs water & carbon dioxide, just like a leaf does, and produces oxygen. It looks like a promising first step towards enabling longer distance space travel – in a way that the artificial leaf made by him could be used to supply oxygen in micro-gravity, in which terrestrial plants have a hard time growing. The artificial leaf he made for his project involves extracted chloroplasts from plant cells laid on a matrix of silk protein.
  • Lightning Trapped Forever in a Box

    Anupum Pant
    28 Jul 2014 | 10:35 am
    By Anupum Pant On a cloudy and stormy night (or almost all the time, in this part of Venezuela), dark clouds separate charges and are able to put together the right conditions to send off one of the nature’s most powerful forces from the heavens – lightning. The air break downs and a great amount of static charge gets transferred through the path of least resistance. And a bolt of bright light is seen for a fraction of a second. It lasts for a very little time. As it happens too quickly, the exact shape of a lightning bolt is difficult to see. However, a long time back, a German…
  • Coldest Spot in The Universe

    27 Jul 2014 | 10:35 am
    By Anupum Pant Where do you think is the coldest spot in the universe. Like many would have guessed, somewhere in the deepest places in space, the temperature would be coldest than anything else. After all, space being so massive, the probability that happening is so high outside of Earth. Probably the Boomerang Nebula is the coldest. At least that is what Google says: At a positively frigid one Kelvin (that equates to –458 degrees Fahrenheit or –272 degrees Celsius), the Boomerang Nebula in the constellation Centaurus is officially the coldest known place in the entire Universe.

  • The Coldest Place on Earth

    Anupum Pant
    25 Jul 2014 | 10:35 am
    By Anupum Pant A couple of days back I wrote about the hottest place on earth. That made me think of how cold the coldest place would be. I was sure it’d be somewhere in one of the poles, but I wasn’t sure where exactly it was. This is what Google said: Aerial photograph of Vostok Station, the coldest directly observed location on Earth. The lowest natural temperature ever directly recorded at ground level on Earth is −89.2 °C (−128.6 °F; 184.0 K), at the Soviet Vostok Station in Antarctica, on July 21, 1983. After a little more digging, I found that his was the old record.

  • Detection Of Pollutant Gases On Alien Worlds As Evidence For Intelligent Life

    wwc
    29 Jul 2014 | 11:11 pm
    Scientists from Harvard’s Center for Astronomy have completed a theoretical study that suggests under the right conditions, existing optical technology is powerful enough to detect atmospheric pollution that would imply presence of intelligence on alien worlds. Current methods call for detecting methane or oxygen as a means to narrow the search for life on alien worlds because these gases are short-lived molecules in the atmosphere in the absence of replenishing sources (although such sources may be abiogenic so are not proof of life).  However these methods do not distinguish between…

    According to a series of articles published in a journal belonging to the Association for Psychological Science, Psychological Science, the degree of subjective knowledge consumers self-report having about a certain product has deep effects on their decision to buy or not. Specifically, the lead author Dr. Liat Hadar says, the study revealed that there are differences in the optimal size of the choice set for selling to the people with high versus low subjective knowledge.  Those with high subjective knowledge should be presented with a small choice set, whereas those with low subjective…
  • Shrouded In Secrecy, British Autonomous Stealth Drone Taranis Takes 2nd Test Flight

    BAE Systems, a British defense company, announced that its highly secret, stealth drone named Taranis has just finished its second set of flight trials in late 2013 and early 2014.  The stealth drone was unveiled in 2010 in the U.K.. The project with a price tag of $316 million is being led by BAE Systems but includes subsidiary builders in both the U.K. and the U.S. such as General Electric.  The drone itself is 10 meters across, comparable to an F-16 at 9.96 m, but less than the F-14 at 20 m, and the F-18 at 14 m.  Inside it is outfitted with artificial intelligence software, an…

    Influenza imposes a heavy annual public health burden, and lies historically at the heart of a number of global pandemics that killed tens of millions.  To overcome the challenges of manufacturing enough vaccines such that we may stave off the next epidemic, medical researchers are searching for ways to strengthen or extend the power of existing and stockpiled vaccines.  Now a team of scientists in Boston has just developed a new method of using laser light to stimulate and enhance the immune response to a vaccine by a remarkable 4 to 7-fold against disease agents. Such treatments that…

But the DOE is not the only funding agency that contributes toward fusion research.  NASA, the DOD, DARPA, and individual national…

    Institute of Hazard, Risk and Resilience Blog - Making a difference to how we live with hazard and risk. Reputation management is imperative to success for business professionals and in banking it is no different. Banks need a favourable reputation to build trust with customers in order to encourage them to deposit their money, take out mortgages or business loans, and purchase financial products. Like any other profession, bankers must manage their activities appropriately to avoid reputational risk. The image of bankers has been damaged since the banking crisis of 2007–08, although the…

    We often forget that some of the simplest pleasures, like a bar of chocolate, is not a treat that is universally enjoyed. The sad fact is that some of our everyday indulgences are to people in other parts of the world, an expensive and lavish extravagance. When you consider that cocoa farmers make only 1.25 in U.S. dollars a day, you realize that a bar of chocolate is about equal in cost to a day of their wages. So despite the fact that these men labor day after day for practically nothing, they have never even tasted the luxury that their own exertion produces. Watch as their faces light up…
  • 10 Examples of How Animals See - Images That Show Us The World Through Their Eyes

    Morgans Lists
    29 Jul 2014 | 11:11 am
    With only our own human perceptions to gauge reality, some of us don't realize that our version of reality is just a combination of measurements defined by the resolution of our senses. We are confined to our own perceptions and the version of reality we see or perceive, through the functions of our various organs, may actually be imperfect and is probably a very dim version of true reality. We cannot actually see through another life form's eyes, at least not yet, but through science we can make a close approximation. We can do this by studying how other animal's eyes are built and how they…

Conservationists had hoped that the petition would force the Obama administration to confront climate change as a threat to ecology and biodiversity worldwide.
