    A very long time ago, a massive meteor, while entering Earth’s atmosphere, broke into two huge pieces. They were at least 6 miles (10 km) across. The impacts on the Australian countryside were violent and spanned nearly 250 miles (400 km). Warburton Basin, Australia, where the world’s largest meteor crater exists. (Screenshot/YouTube) So what’s the difference between an asteroid, a meteor, and a meteorite? These words are mistakenly used interchangeably. A simple explanation is that an asteroid is a rock that is out in space, a meteor is an asteroid that enters the…

    Will this be the year of the force field? Boeing filed a patent for a “method and system for shockwave attenuation via electromagnetic arc” in 2012. It may have been easier to call it a deflector shield. The patent describes it as a system that detects shockwaves from nearby explosions and generates an area of ionized air—creating a plasma field between the blast and the vehicle. Boeing’s plasma field. (Image: Boeing’s Patent and Trademark Office file) The method works, says the patent, “by heating a selected region of the first fluid medium rapidly to create a…

  • Common metal addles honey bee brains

    Diana Lutz-WUSTL
    26 Mar 2015 | 8:39 am
    At levels considered safe for human food, a common industrial pollutant called manganese can knock honey bees off their game. A new study shows that when exposed to the metal, honey bees advance through age-related work assignments faster than normal, but complete fewer foraging trips than their unexposed sisters. “We’ve known for a long time that high doses of manganese kill neurons that produce dopamine, causing a Parkinsonian-like disease in people,” says Yehuda Ben-Shahar, a biologist at Washington University in St. Louis. “In insects, as well, high levels of…

    A new geologic history of the flow of water in Jezero crater near Mars’ equator says interesting things about how the red planet operated nearly four billion years ago, scientists say. “We can say that this one really well-exposed location makes a strong case for at least two periods of water-related activity in Mars’ history,” says Tim Goudge, a graduate student at Brown University. The ancient lake at Jezero crater was first identified in 2005. Researchers identified two channels on the northern and western sides of the crater that appear to have supplied it with…

    Scientists call the different realms of life on Earth “biomes,” and the fastest growing one is actually indoor space. Researchers estimate that the indoor biome makes up about 0.5 percent of ice-free land, or about 247,000 square miles, almost the size of Texas. The various organisms living in homes and other indoor spaces have been subject to little research, with sparse studies of rodents and German cockroaches, for example, from the pest management field, or public health perspectives on microbes. “People have this picture that there are only a few insect species and…

A new study that assesses the “criticality” of all 62 metals on the Periodic Table of Elements offers key insights into which metals will be scarce, which will exact the highest environmental costs, and which ones simply cannot be replaced as components of vital technologies. Researchers were inspired to try to quantify the criticality of the materials—defined by the relative…

  • 15 Breeds Of Dog In England Killed By Mystery Kidney Disease 

    News Staff
    26 Mar 2015 | 10:44 am
    At least 30 dogs in England have been killed in less than 18 months by an unknown disease which causes skin lesions and kidney failure, reveals research published in Veterinary Record. The disease is believed to be Alabama rot (cutaneous and renal glomerular vasculopathy), a condition which has been seen in the USA in greyhounds for almost 30 years. While there have been occasional reports of the disease in individual dogs outside of the USA, this is the first report of a series of cases occurring in England. None of the 30 dogs in this English series of cases were greyhounds and evidence of…

    Milk is a key element for household food security and provides a stable income to farmers including women, who are usually in charge of taking care of the milk-producing animals in the low-income countries. Currently pathogen growth in milk is managed with refrigeration or with chemicals. Although bacterial growth in milk is managed with refrigeration in the high-income countries, a high cost of infrastructure and a demand for a permanent electricity supply prevent milk refrigeration in the rural areas in the low-income countries. Moreover, certain pathogens, for example Listeria…

    The Psychologist has a fascinating article on how neuroscience fits in to our understanding of mental illness and what practical benefit brain science has – in lieu of the fact that it currently doesn’t really help us a great deal in the clinic. It is full of useful ways of thinking about how neuroscience fits into our view of mental distress. The following is a really crucial section, that talks about the difference between proximal (closer) and distal (more distant) causes. In essence, rather than talking about causes we’re probably better off talking about causal pathways –…

    I’ve got an article in The Observer about how the official definition of trauma keeps changing and how the concept is discussed as if it were entirely intuitive and clear-cut, when it’s actually much more complex. I’ve become fascinated by how the concept of ‘trauma’ is used in public debate about mental health and the tension that arises between the clinical and rhetorical meanings of trauma. One unresolved issue, which tests mental health professionals to this day, is whether ‘traumatic’ should be defined in terms of events or reactions. Some of the…

    The computational approach is the orthodoxy in psychological science. We try and understand the mind using the metaphors of information processing and the storage and retrieval of representations. These ideas are so common that it is easy to forget that there is any alternative. Andrew Wilson is on a mission to remind us that there is an alternative – a radical, non-representational, non-information processing take on what cognition is. I sent him a few questions by email. After he answered these, and some follow up questions, we’ve both edited and agreed on the result, which you can…

  • A defense of ENCODE? [Pharyngula]

    Dan Graur has snarled at the authors of a paper defending ENCODE. How could I then resist? I read the offending paper, and I have to say something that will weaken my own reputation as a snarling attack dog myself: it does make a few good points. But it’s mostly using some valid criticisms to defend an indefensible position. Here’s the abstract. In its last round of publications in September 2012, the Encyclopedia Of DNA Elements (ENCODE) assigned a biochemical function to most of the human genome, which was taken up by the media as meaning the end of ‘Junk DNA’.

Queller The evolution of sterile worker castes in eusocial insects was a major problem in evolutionary theory until Hamilton developed a method called inclusive fitness. He used it to show that sterile castes could evolve via kin selection, in which a gene for altruistic sterility is favored when the altruism sufficiently benefits relatives carrying the gene. Inclusive fitness theory is well supported empirically and has been applied to many other areas, but a recent paper argued that the general method of inclusive fitness was wrong and advocated an…

  • A Biologically Plausible Computational Theory for Value Integration and Action Selection in Decisions with Competing Alternatives

    Vassilios Christopoulos et al.
    24 Mar 2015 | 2:00 pm
    by Vassilios Christopoulos, James Bonaiuto, Richard A. Andersen Decision making is a vital component of human and animal behavior that involves selecting between alternative options and generating actions to implement the choices. Although decisions can be as simple as choosing a goal and then pursuing it, humans and animals usually have to make decisions in dynamic environments where the value and the availability of an option change unpredictably with time and previous actions. A predator chasing multiple prey exemplifies how goals can dynamically change and compete during ongoing actions.

A bow-tie in a multi-layered structure occurs when intermediate layers have much fewer components than the input and output layers. Examples include metabolism where a handful of building blocks mediate between multiple input nutrients and multiple output biomass components, and signaling networks where information from numerous receptor types passes through a small set of signaling pathways to regulate multiple output genes.

  • When Can Species Abundance Data Reveal Non-neutrality?

    by Omar Al Hammal, David Alonso, Rampal S. Etienne, Stephen J. Cornell Species abundance distributions (SAD) are probably ecology’s most well-known empirical pattern, and over the last decades many models have been proposed to explain their shape. There is no consensus over which model is correct, because the degree to which different processes can be discerned from SAD patterns has not yet been rigorously quantified. We present a power calculation to quantify our ability to detect deviations from neutrality using species abundance data. We study non-neutral stochastic community models, and…
  • On the Number of Neurons and Time Scale of Integration Underlying the Formation of Percepts in the Brain

    Adrien Wohrer et al.
    20 Mar 2015 | 2:00 pm
    by Adrien Wohrer, Christian K. Machens All of our perceptual experiences arise from the activity of neural populations. Here we study the formation of such percepts under the assumption that they emerge from a linear readout, i.e., a weighted sum of the neurons’ firing rates. We show that this assumption constrains the trial-to-trial covariance structure of neural activities and animal behavior. The predicted covariance structure depends on the readout parameters, and in particular on the temporal integration window w and typical number of neurons K used in the formation of the percept.

Few empirical studies have examined dynamic resource allocation decisions systematically. Here we conducted an experiment involving the dynamic consumption over approximately 15 minutes of a limited budget of relief from moderately…

    by Yemima Budirahardja, Thang Dinh Doan, Ronen Zaidel-Bar Glycosylphosphatidylinositol (GPI) is a post-translational modification resulting in the attachment of modified proteins to the outer leaflet of the plasma membrane. Tissue culture experiments have shown GPI-anchored proteins (GPI-APs) to be targeted to the apical membrane of epithelial cells. However, the in vivo importance of this targeting has not been investigated since null mutations in GPI biosynthesis enzymes in mice result in very early embryonic lethality. Missense mutations in the human GPI biosynthesis enzyme pigv are…

  • A Cascade of Iron-Containing Proteins Governs the Genetic Iron Starvation Response to Promote Iron Uptake and Inhibit Iron Storage in Fission Yeast

    Javier Encinar del Dedo et al.
    25 Mar 2015 | 2:00 pm
    by Javier Encinar del Dedo, Natalia Gabrielli, Mercè Carmona, José Ayté, Elena Hidalgo Iron is an essential cofactor, but it is also toxic at high levels. In Schizosaccharomyces pombe, the sensor glutaredoxin Grx4 guides the activity of the repressors Php4 and Fep1 to mediate a complex transcriptional response to iron deprivation: activation of Php4 and inactivation of Fep1 leads to inhibition of iron usage/storage, and to promotion of iron import, respectively. However, the molecular events ruling the activity of this double-branched pathway remained elusive. We show here that Grx4…

    by Julia Esser-von Bieren, Beatrice Volpe, Duncan B. Sutherland, Jérôme Bürgi, J. Sjef Verbeek, Benjamin J. Marsland, Joseph F. Urban, Nicola L. Harris Helminth parasites can cause considerable damage when migrating through host tissues, thus making rapid tissue repair imperative to prevent bleeding and bacterial dissemination particularly during enteric infection. However, how protective type 2 responses targeted against these tissue-disruptive multicellular parasites might contribute to homeostatic wound healing in the intestine has remained unclear.

    by Linya Wang, Yongjun Tian, Jing-hsiung James Ou Hepatitis C virus (HCV) induces autophagy to enhance its replication. However, how HCV regulates the autophagic pathway remains largely unclear. In this report, we demonstrated that HCV infection could induce the expression of Rubicon and UVRAG, which inhibited and stimulated the maturation of autophagosomes, respectively. The induction of Rubicon by HCV was prompt whereas the induction of UVRAG was delayed, resulting in the accumulation of autophagosomes in the early time points of viral infection. The role of Rubicon in inhibiting the…

    Data journalism is relatively new as a concept, but in practice it has been around for a good while. Scott Klein for ProPublica tells the story of Horace Greeley, an editor for the New York Tribune and a congressman in the mid-1800s. Greely was displeased with a law that specified mileage compensation for travel to the capital, so he found a way to prove his point with data. Rather than simply opining against it, he conceived and published a data-journalism project that, in form if not in execution, would be very much at home in a newsroom today. He asked one of his reporters, Douglas Howard,…

"Many people suffer from chronic pain, and the level of pain experienced can be higher than would be expected from actual tissue damage. Our research is basic laboratory science, but it raises the interesting possibility that pain levels could be manipulated by applying additional stimuli, and by moving one part of the body relative to others," the senior author explained.

  • 5 Human Body Questions the 1-Year Space Station Mission May Answer

    26 Mar 2015 | 6:54 am
    NASA has a lot of questions about what happens to people who live in space for long periods of time, and it's almost time to get some answers. When NASA astronaut Scott Kelly and Russia's Mikhail Kornienko fly up to the International Space Station Friday (March 27) for a yearlong stay on the orbiting outpost, space agency scientists will get to work on experiments that could help get people to Mars one day. Officials have a lot of information about what happens to a body in weightlessness for six months, but the 12-month space mission will mark the first time researchers can gather…
  • New Tech Could Protect Astronauts' Eyes on Mars Mission

    26 Mar 2015 | 6:53 am
    Three new technologies could help keep astronauts' vision sharp during a mission to Mars. The National Space Biomedical Research Institute (NSBRI) Industry Forum earlier this month funded three companies as part of its "Vision for Mars" challenge, which seeks to encourage the development of tech that can mitigate the visual problems astronauts experience during long-term spaceflight. For example, astronauts aboard the International Space Station must exercise vigorously every day to stave off muscle atrophy and a decrease in bone density. Such health issues are a real concern…
  • How Real-Life AI Rivals 'Terminator': Robots Take the Shot

    26 Mar 2015 | 5:48 am
    From the Turing-bashing "Ex Machina" to old friends R2-D2 and C-3PO, and new enemies like the Avengers' Ultron, sentient robots will demonstrate a number of human and superhuman traits on-screen. In this five-part series Live Science looks at these made-for-the-movies advances in machine intelligence. As he's so often promised, Arnold Schwarzenegger will be back, once again taking on his iconic killer-robot role in July's "Terminator Genisys." While no Skynet-like AI has sent red-eyed robots after humanity (thankfully), the prospect of weaponized AI has…

  • Science as Sport? Improve Your Work by Changing Your Perspective

    Dave McGarry
    25 Mar 2015 | 5:00 am
    “You think you know, but you don’t know and you never will, okay?” was the response an irate Jim Mora, head coach of the New Orleans Saints, gave to an unwitting journalist questioning his management – his point being that unless you’ve actually been in a professional sports team, you will never know what it’s like to coach at the top level. The similarity isn’t too far away from life as a PhD student or postdoc. Unless you’ve experienced trying to get your own project off the ground, it’s quite hard to describe to your family and friends what science life is like.
  • Five Easy Ways to Reduce Word Count

    Kristin Harper
    23 Mar 2015 | 5:00 am
    The NIH grant that you are working on only gives you five pages to describe your research strategy. You’re wrestling with a research report for Science that has a maximum word limit of 2500. And the abstract for the conference you’d like to speak at this spring only allows you 300 words to summarize the work you will be presenting. Sound familiar? If you are a scientist, chances are that you have spent plenty of time struggling to reduce the word count of various documents. Here are five helpful hints for communicating your ideas more succinctly, with examples to make the process easier.
  • The 4 Important Steps for Western Blot Quantification

    Melanie Laederich
    20 Mar 2015 | 11:43 pm
    As scientists we love nothing more than quantitative data! Oh ya! But if you don’t quantify your Western blots correctly you’ll find yourself in an unpleasant, unrepeatable and totally meaningless place. And while some scientists are okay dwelling in a meaningless place, I hope you are not. Review these important concepts about how to correctly quantitate your next Western blot. 1. Find the Linear Range For quantitate analysis of an image you must ensure your image was captured in a manner sensitive enough to detect change, in what we call the “linear range”. If you are not working…
  • The Why and How of Oil Immersion Microscopy

    Martin Wilson
    20 Mar 2015 | 11:43 pm
    Do you know why immersion oil and objectives are used for high power magnification? Do you know how to use an immersion objective correctly? Then review with me the why and how of immersion objectives. The quality of your image depends on your Numerical Aperture (NA) and resolution. To very briefly recap, NA relates to the light gathering properties of the optical components of your microscope, whereas resolution is your ability to distinguish details within your specimen. Using an immersion lens and oil can improve both your resolution and NA. Now let us take a look at why this is.

    Scientists are working to gather more and more details about Icelandic DNA, in an attempt to design better drugs and understand how drugs react to genetic variation. So far, the DNA of over 1% of all Icelanders has been sequenced and more will likely follow. This operation is conducted by Amgen's DeCode Genetics. The team now claims that they can identify every woman at high-risk of breast cancer "at the touch of a button" and it would be "criminal" not to use the information.

Now, researchers from the University of Utah have identified another one of these thinner layers, 930 miles beneath our feet.

    There are fewer people connected to nature now than ever before—and no one connected to it in the same way as the Hadza. One of the last hunter-gather groups on earth, the Hadza have lived sustainably off the bounty of their ancestral homeland in Africa’s Rift Valley for at least 50,000 years. But their unique culture and way of life, including the ability to source 95 percent of their diet from the wild, has been threatened by issues as varied as continuing encroachment, aggressive tree-cutting and over-grazing.

  • Why no tropical milkweed at the Cockrell Butterfly Center plant sale this year?

    Aslepias curassavica We are sorry to disappoint monarch enthusiasts, but the Cockrell Butterfly Center has decided not to sell tropical milkweed (aka Mexican milkweed, Asclepias curassavica) any more. Instead, we will have a limited quantity of native milkweeds for sale. Recently, biologists studying monarchs have discovered that tropical milkweed may be a factor in the spread of a parasitic infection that attacks monarchs. The infection is called Oe (short for Ophryocystis elektroscirrha) and is transmitted by spores that fall from an infected female’s body onto the hostplant when she lays…

    On January 12, 2015, police officers escorted Hal and Michelle Stanley out of their Arkansas home. For five hours they searched the house. Eventually officers found a dietary supplement that was bought over the Internet: MMS (Miracle Mineral Solution, also known as Master Mineral Solution).

    11 Mar 2015 | 1:38 pm
    The next issue of our magazine—the very first issue of Distillations, by the way—takes a look at World War I and the history of chemical weapons. In the months I spent working on the articles, I was struck time and again by the cruelty and stupidity of war and things men are willing to do to one another. More than anything, I’m putting the issue to bed with my beliefs reaffirmed that war is a horrible, pointless thing. This is evident in the staggering numbers of those injured and killed, in the images of maimed and disfigured soldiers, the absurd rhetoric of wartime propaganda, and…

    Stop the Press!The Distillations egg is finally hatching. After more than a year of hard work we finally printed the first issue of Distillations Magazine.  It’s a redesign and reimagining of Chemical Heritage, which has, in its many forms, been around since the 1980s. We spent two long days at our printers last week watching the birth. The long silver and green rectangular box thing is a Heidelberg printing press, which can print 17,000 identical sheets in about 3 hours. It’s an offset printer rather than a digital printer, which means four metal plates are used to print each magazine…

    Some technologies flash in the pan so quickly they hardly leave a trace (Google Glass anyone?); while others seem to stick around long past their use by date. And still other creations appear to be gone for good, only to make a comeback within a niche—and likely nostalgic—community. We set out to explore the rhymes and reasons behind these ebbs and flows of technological innovation and obsolescence. First we go to a place where digital nostalgia is alive and well: a vintage video arcade outside of Chicago. Reporter Colleen Pellissier tells the story of one man who dedicates his life to…

    25 Feb 2015 | 8:20 am
    You wouldn’t know a limpet had teeth from looking at it. These soft, squishy sea snails cling to rocks and scrape algae into their mouths, which means their teeth need to be stronger than rock. Last week, a paper in the Royal Society’s journal Interface published the results of a limpet tooth stress test. It turns out that these teeth are the strongest biological material on the planet. (We wrote about graphene a few months ago, which is one of the strongest human-made materials.)The study reports that the teeth can take between 3.0 to 6.5 GPa (gigapascals) of stress before failing.

    Star formation takes place in cold, dense molecular clouds. By heating and dispersing gas that could one day make stars, the black-hole wind forever alters a large portion of its galaxy. By combining observations from the Japan-led Suzaku X-ray satellite and the European Space Agency's infrared Herschel Space Observatory, scientists have connected a fierce "wind" produced near a galaxy's monster black hole to an outward torrent of cold gas a thousand light-years across. The finding validates a long-suspected feedback mechanism enabling a supermassive black hole to influence the evolution of…

    Scientists have tapped the briny bottom of a subglacial ecosystem that flows into Antarctica’s Lake Bonney, according to The Antarctic Sun. The area where the fluid comes out has come to be known as “Blood Falls,” after its red color. Of course, the fluid isn’t actually blood – it’s an iron-rich, saline liquid that looks red when it reaches the surface. Previous investigations, like one in 2004, had tried to sample the brine, but introduced error because their samples had been exposed to Antarctic air and water. To get around the problems of studies past, researchers from U.S.

    Russia’s Lake Baikal is shrinking, according to Reuters. But that’s one of the smaller problems plaguing the world’s largest freshwater lake. One of the bigger ones, experts say, is the rise of non-native algae. Lower water levels can be explained by hydropower plants along rivers that feed Lake Baikal. The algae problem – well that is likely due to increases in biological waste. This has been boosted by discharging sewage facilities in local holiday centers near the lake, according to Russia Today.

      Article by Lauren Farrar Scientists at the California Academy of Sciences have recently engineered a device that allows them to collect newly-discovered fish species from the ocean’s “twilight zone” and safely bring them up to the surface to study. Prior to this invention, it was difficult for scientists to study fish in this region because many fish can’t handle the rapid change in pressure they experience when being transported to the surface. In water, pressure increases with depth. When you are submerged in a body of water, like the ocean, you experience pressure from the…

      Article by Lauren Farrar Deep below the ocean’s surface lies a mysterious region known as the “twilight zone.” Located 200 to 500 feet beneath the surface, this region receives scarce amounts of light, mimicking twilight—the time of day just after sunset. Some areas of the twilight zone are vast ocean space, but some are home to incredible coral reefs. Scientists have many unanswered questions about this region, in part because it is so hard to reach. Diving to these depths requires specialized training and gear, and takes hours to safely ascend. Bart Shepherd and Luiz Rocha at…

    Orbiting Spheres Right on cue, day turned into a sudden eerie twilight as a great swathe of the Earth's surface quickly plunged into transient darkness.  The magic number is 400.  For many observers, weather conditions were far from ideal.  Clouds obscured the much awaited spectacle of the 2015 eclipse.  Thankfully, alternatives were available to astronomers keen not to miss the big event...  Weather conditions did not play nice in Central Scotland... The Sun finally emerges from the clouds and rain at the end of the eclipse. On the day of the…

    Polar Equinoctial Eclipse 2015 On 20th March 2015, the Moon will pass in front of the Sun and exactly block out most of its light.  It will be the first total solar eclipse of the 21st century that is visible from the northernmost regions of Europe... Full solar eclipses are comparatively infrequent astronomical events because the Moon's orbit is tilted and not quite in the same plane relative to the Earth's orbit, making it even rarer when the Sun, the Moon and the Earth align.  That this can happen at all is due to a remarkable coincidence. Although the Sun is much bigger than the…

    Everyday Matter Four states of matter can be seen in everyday life: solid, liquid, gas, and - somewhat more exotically - plasma.  As a tightly bound combination of oxygen and hydrogen atoms, a water molecule is nothing out of the ordinary.  Liquid water, steam or ice are still just water.  Yet, it is intriguing to see how the very same building blocks of matter are capable of producing such broadly distinct states. As far as water is concerned, one phase can change into another really quite abruptly.  At 99 °C, liquid water can subsist, whereas at 101 °C, water is in its…

So it’s been around a while. I’m not including ‘mediums’ in this article. I think that’s a slightly different field and should be dealt with in an article of its own. For the record though, I think it’s all bunkum until I find evidence to the contrary.

    By Anupum Pant Florescence is a physical phenomena in which light (electromagnetic radiation) is absorbed by a substance with certain properties and is instantly emitted back in a different wavelength. Most times the absorbed light of a certain wavelength is emitted back by the substance with a greater wavelength. This leads to one interesting phenomenon in which the smaller wavelength UV radiation (which is invisible to the human eye) gets converted to a visible light by the substance. Applications of this particular phenomenon are numerous, in the modern world. The white fluorescent lamps…

    It’s difficult for me to resist roadside dinosaurs. I probably should invest in an “I brake for dinosaurs” bumper sticker at this point. So when I realized that I’d be passing close to Connecticut’s Dinosaur State Park, my plans were set. I hopped in the car and sped up the highway to the Jurassic.

    Sophie the Stegosaurus. Photo courtesy NHM London. Talking about dinosaurs sometimes reminds me of sports fans going over a player’s vital statistics. It’s important to know a player’s RBIs or interceptions (I think; I know practically nothing of sports), just like any hardcore dinosaur fan is going to know the diet, length, and other details of a particular species. Some of these particulars are relatively easy to come by. Curved serrated teeth? Then the dinosaur’s likely a carnivore. But others are trickier. How do we know how much non-avian dinosaurs weighed when we…

The term MOF was coined by Omar Yaghi in 1995 (1). MOFs consist of both organic and inorganic building entities, where the organic ligands, i.e. spacers, are coordinated to the metal ion clusters, i.e. nodes, to create extended frameworks. In some cases, the frameworks are rigid enough to form internal voids after solvent removal, forming structures with high…

In fact, the Slow Mo Guys did hit 100 mph to take full advantage of the convertible car aerodynamics and just a slight decrease in the speed could affect how the aerodynamics of a convertible’s windshield/windscreen work. How aerodynamics works also depends on the velocity and the direction of the wind. For example, if the velocity of the wind is 60 miles per hour, the aerodynamics would still function if you are driving at about 40…
