    Scientists have discovered a gene involved in determining the melting point of cocoa butter, a critical attribute of the substance widely used in foods and pharmaceuticals. The finding could lead to new and improved products, say researchers. The finding by plant geneticists could also lead to new varieties of the cocoa plant that could extend the climate and soil-nutrient range for growing the crop and increase the value of its yield, they say, providing a boost to farmers’ incomes in the cocoa-growing regions of the world. Cacao, Theobroma cacao L., is an understory tropical tree…

  • Stone Age toolmakers deserve more respect

    Carol Clark-Emory
    17 Apr 2015 | 11:16 am
    Making a Stone Age hand axe took serious brain power, experts say. The skill of making a prehistoric hand axe is “more complicated and nuanced than many people realize,” says Dietrich Stout, an experimental archeologist at Emory University. “It’s not just a bunch of ape-men banging rocks together. We should have respect for Stone Age toolmakers.” A new study led by Stout and published in PLOS ONE shows the ability to make the hand axe depends on complex cognitive control by the prefrontal cortex, including the “central executive” function of working…

  • 34% of women with ADHD report sexual abuse

    Adults who have ADHD are much more likely to report they were sexually and physically abused before they turned 16 than their peers without ADHD, according to a new study. Among women, 34 percent of those with ADHD reported they were sexually abused before they turned 18. In contrast, 14 percent of women without ADHD reported that they had experienced childhood sexual abuse. Twice as many women with ADHD reported that they had experienced childhood physical abuse than women without this condition (44 percent vs 21 percent). “These findings suggest there is a silent epidemic of abuse…

    A technique that removes blood clots from large brain blood vessels after stroke is highly effective at reducing disability. The results are from a trial conducted in Catalonia, Spain, and confirm findings from other recent large studies that were stopped early when the technique, called endovascular therapy or stent retriever thrombectomy, led to such improved outcomes, says Tudor Jovin, co-principal investigator. “This is a giant step forward that will change the way we approach triage and treatment of stroke patients,” adds Jovin, associate professor of neurology and…
  • Are women actually better at negotiation?

    U. Florida

    Women with successful negotiation experience are better negotiators than men, even when they rate themselves as average at it, a new study finds. The research got its start when University of Florida student Samantha Miller was listening to a lecture on a commonly held trope about negotiation—that women are bad at it. That conventional wisdom didn’t fit with her experience at all. “I hope people shut up about gender and talk about the framework that informs gender bias.” “I always ask what I feel I’m deserving of,” she says. “I had an idea that…

  • Stomach Ulcers In Cattle

    18 Apr 2015 | 4:00 pm
    Scientists at the Vetmeduni Vienna investigated whether stomach ulcers in cattle are related to the presence of certain bacteria. For their study, they analyzed bacteria present in healthy and ulcerated cattle stomachs and found very few differences in microbial diversity. Bacteria therefore appear to play a minor role in the development of ulcers. The microbial diversity present in the stomachs of cattle has now been published. read more

    The two heaviest naturally occurring radioactive elements on the earth are Uranium and Thorium.  Uranium is used as a fuel in modern commercial nuclear power reactors for electricity generation.  A lesser known fact is that thorium could also be used as a nuclear fuel .  Naturally occurring thorium is not fissile and so not able to undergo nuclear fission (separation) and as such it takes an initial nuclear reaction to enable this process. read more

    When we’re in our teens, it’s common that we first discover the music we see as our own, discarding the vinyl our parents played, and kicking back on beats to our own tune. For me it was a migration from 60s pop to 70s prog and hard rock. But, when you get to middle age you might find yourself living in some kind of shack and you may ask yourself, well what do I listen to now, as you let the days go by? For me, I’ve revisited many of those “discs” my parents played, but digesting them via a stream of 1s and 0s rather than ass the amplified jitterings of a…

    A catchy pop song of 2014 had the refrain “I’m all about that bass, no treble” or somesuch throwaway line. The accompanying video, much parodied and pastiched, was popular on teh interwebz and was apparently all about raising body image awareness and itself a pardoy of the modern pop culture in which certain characteristics of the female and male form are emphasised in a modern grotesque.. Anyway, in the spirit of scientific endeavour I did a quick frequency analysis of the song to ascertain whether it really was “all about the bass”. And, guess what?

    Following the Deepwater Horizon Oil Spill in 2010, many people were concerned that seafood was contaminated by either the oil or dispersants used to keep the oil from washing ashore. Ina University of Florida study, all seafood tested so far has shown "remarkably low contaminant levels," based on FDA standards, and revealed that: * 74 percent of samples were below quantifiable limits; * 23 percent of samples were between 0.1-0.9 parts per billion, and; * 3 percent of samples were between 1.0 and 48 parts per billion.

    17 Apr 2015 | 2:00 pm
    by Anna Lenard, Stephan Daetwyler, Charles Betz, Elin Ellertsdottir, Heinz-Georg Belting, Jan Huisken, Markus Affolter During embryonic development, vascular networks remodel to meet the increasing demand of growing tissues for oxygen and nutrients. This is achieved by the pruning of redundant blood vessel segments, which then allows more efficient blood flow patterns. Because of the lack of an in vivo system suitable for high-resolution live imaging, the dynamics of the pruning process have not been described in detail. Here, we present the subintestinal vein (SIV) plexus of the zebrafish…

Brown Twilight is characterised by changes in both quantity (“irradiance”) and quality (“colour”) of light. Animals use the variation in irradiance to adjust their internal circadian clocks, aligning their behaviour and physiology with the solar cycle. However, it is currently unknown whether changes in colour also contribute to this entrainment process. Using environmental measurements, we show here that mammalian blue–yellow…

Diptera flies, which include the model Drosophila melanogaster, generally have XY sex chromosomes and a conserved karyotype consisting of six chromosomal arms (five large rods and a small dot), but superficially similar karyotypes may conceal the true extent of sex chromosome variation. Here, we use whole-genome analysis in 37 fly species belonging to 22 different families of Diptera and uncover tremendous hidden diversity in sex chromosome karyotypes…

Glioblastoma is the most common, aggressive and highly malignant type of primary brain tumor. The average overall survival remains less than 1 year. Notably, cancer patients with obesity and diabetes have worse outcomes and accelerated progression of glioblastoma. The root cause of this accelerated progression has been hypothesized to involve the insulin signaling pathway. However, while the process of invasive glioblastoma…

    Stuart Aitken et al.
    17 Apr 2015 | 2:00 pm
    by Stuart Aitken, Shigeyuki Magi, Ahmad M. N. Alhendi, Masayoshi Itoh, Hideya Kawaji, Timo Lassmann, Carsten O. Daub, Erik Arner, Piero Carninci, Alistair R. R. Forrest, Yoshihide Hayashizaki, the FANTOM Consortium , Levon M. Khachigian, Mariko Okada-Hatakeyama, Colin A. Semple The immediate-early response mediates cell fate in response to a variety of extracellular stimuli and is dysregulated in many cancers. However, the specificity of the response across stimuli and cell types, and the roles of non-coding RNAs are not well understood. Using a large collection of densely-sampled time series…
  • Emergent Systems Energy Laws for Predicting Myosin Ensemble Processivity

    Paul Egan et al.
    17 Apr 2015 | 2:00 pm
    by Paul Egan, Jeffrey Moore, Christian Schunn, Jonathan Cagan, Philip LeDuc In complex systems with stochastic components, systems laws often emerge that describe higher level behavior regardless of lower level component configurations. In this paper, emergent laws for describing mechanochemical systems are investigated for processive myosin-actin motility systems. On the basis of prior experimental evidence that longer processive lifetimes are enabled by larger myosin ensembles, it is hypothesized that emergent scaling laws could coincide with myosin-actin contact probability or system…

    by Christiaan A. de Leeuw, Joris M. Mooij, Tom Heskes, Danielle Posthuma By aggregating data for complex traits in a biologically meaningful way, gene and gene-set analysis constitute a valuable addition to single-marker analysis. However, although various methods for gene and gene-set analysis currently exist, they generally suffer from a number of issues. Statistical power for most methods is strongly affected by linkage disequilibrium between markers, multi-marker associations are often hard to detect, and the reliance on permutation to compute p-values tends to make the analysis…

  • A Redox Regulatory System Critical for Mycobacterial Survival in Macrophages and Biofilm Development

    Kerstin A. Wolff et al.
    17 Apr 2015 | 2:00 pm
    by Kerstin A. Wolff, Andres H. de la Peña, Hoa T. Nguyen, Thanh H. Pham, L. Mario Amzel, Sandra B. Gabelli, Liem Nguyen Survival of M. tuberculosis in host macrophages requires the eukaryotic-type protein kinase G, PknG, but the underlying mechanism has remained unknown. Here, we show that PknG is an integral component of a novel redox homeostatic system, RHOCS, which includes the ribosomal protein L13 and RenU, a Nudix hydrolase encoded by a gene adjacent to pknG. Studies in M. smegmatis showed that PknG expression is uniquely induced by NADH, which plays a key role in metabolism and redox…

    Tobias Dörr et al.
    17 Apr 2015 | 2:00 pm
    by Tobias Dörr, Brigid M. Davis, Matthew K. Waldor In many bacteria, inhibition of cell wall synthesis leads to cell death and lysis. The pathways and enzymes that mediate cell lysis after exposure to cell wall-acting antibiotics (e.g. beta lactams) are incompletely understood, but the activities of enzymes that degrade the cell wall (‘autolysins’) are thought to be critical. Here, we report that Vibrio cholerae, the cholera pathogen, is tolerant to antibiotics targeting cell wall synthesis. In response to a wide variety of cell wall- acting antibiotics, this pathogen loses its rod…

Kehrl Neutrophils form the first line of host defense against bacterial pathogens. They are rapidly mobilized to sites of infection where they help marshal host defenses and remove bacteria by phagocytosis. While splenic neutrophils promote marginal zone B cell antibody production in response to administered T cell independent antigens, whether neutrophils shape humoral immunity in other lymphoid organs is controversial.

    by Jue Hou, Fan Wang, Peizhong Kong, Peter K. N. Yu, Hongzhi Wang, Wei Han Radioadaptive response (RAR) in mammalian cells refers to the phenomenon where a low-dose ionizing irradiation alters the gene expression profiles, and protects the cells from the detrimental effects of a subsequent high dose exposure. Despite the completion of numerous experimental studies on RAR, the underlying mechanism has remained unclear. In this study, we aimed to have a comprehensive investigation on the RAR induced in the AG01522 human fibroblasts first exposed to 5 cGy (priming dose) and then followed by 2 Gy…

    By Elly Park New York, NEW YORK - Scientists at Columbia University in New York have successfully built a camera that is capable of producing images using power harvested from the surrounding incident light.  The prototype self-powering camera takes an image each second, and in a well-lit scene it can operate indefinitely. The team is led by Shree Nayar, Professor of Computer Science at Columbia Engineering,  "What we have designed here is an image sensor with pixels, with this new design that can not only capture pictures but also generate power from the pixels, in order to capture the…

  • 10 Handy Tips to Help Keep Your PCRs Contamination Free

    Bhavyasri Vennapusa
    16 Apr 2015 | 4:30 am
    PCR contamination can be your worst nightmare if you are not able to figure out the source of the bands in your negative control. Initially, when I had to setup PCRs, contamination was my main problem and it remained a mystery for a while, as no matter how many times I repeated it with a new set of everything, I was not able to get rid of it. After a lot of trial and error, I finally managed to solve the problem. So here are the steps I followed to prevent PCR contamination. 1. Wear Gloves that Fit Like a Second Skin I used to wear small size gloves since my correct size (XS) was not…

  • Live-Cell Imaging: Choosing the Right Technique

    ZEISS
    14 Apr 2015 | 2:00 am
    If you want to see in real time what is going on inside your cell then you should be performing live-cell imaging. These techniques allow real-time examination of almost every aspect of cellular function under normal and experimental conditions. With all live-cell imaging experiments, the main challenges are to keep your cells alive and healthy over a period of time while they are on the stage of the microscope. Your cells must be kept in a temperature- and pH-stable environment, which is usually achieved by using a chamber where the cells are placed, or larger environmental chambers around…
  • The Benefits of Being Single: Genomic Analysis of Single Cells

    Laura Fulford
    13 Apr 2015 | 9:53 am
    You don’t need to be told about how next generation sequencing technologies have revolutionized the way we study the genome and the epigenome. Whether you want to look at transcription (RNA-seq), translation (Ribo-seq) genomes (DNA-seq), interactions of proteins and DNA (ChIP-Seq) or to study epigenetic features such as methylation (whole genome bilsulfite sequencing) there are a range of techniques available to you. Why Study Single Cells? All these techniques require vast numbers of cells (normally in the millions). This has several downsides: what if you are looking for rare mutations or…

    If there is a job in the world that requires one of the highest levels of motivation, I would say it is doing a PhD. Pushing yourself out of bed daily to enter the lab ain’t an easy task, especially when your results are dodgy or you have unluckily found that your lab-mates or project colleagues are not the kind of people you really gel with. Anything from a tough project, elusive results to not-so-helpful colleagues can bring your motivation down. But I have always believed that when the going gets tough, the tough gets going! So on that Mantra, here I am, a PhD student, thinking about…

  • NASA can only make three more Plutonium batteries to power spacecraft in space

    Tibi Puiu
    18 Apr 2015 | 9:11 am
    According to the Department of Energy, the plutonium-238 stockpile is enough to make only three more nuclear batteries. These are used to power long-term space missions, like Curiosity rover now studying Mars on site, the Voyager probes which were launched in the 1970s and are now almost out of the solar system or New Horizon which is close to making the first Pluto flyby in history. New Horizon is also the fastest spacecraft ever built, racing at one million miles per day. All these remarkable achievements were made possible thanks to plutonium-238 and the technology developed to harness its…

    Tibi Puiu
    17 Apr 2015 | 1:47 am
    Despite lacking a rigid skeleton, octopuses have a remarkable coordinated locomotion. Using high-speed cameras, a group at the Hebrew University of Jerusalem found the octopus achieves this by precisely and independently moving one or more of its eight legs to crawl its body, even when its facing a different direction. Moreover, there is no discernible rhythm or pattern to this undulating leg movement, making the octopus unique in this respect. It's controlled chaos, and only the octopus itself completely knows how it pulls all this off.

    Do these dolls look familiar? In 1997 Intel released the Pentium II processor and advertised it with commercials starring “BunnyPeople.” That name is not a reference to the animals with floppy ears; bunny suits are protective clothing worn by lab technicians who build microprocessors. The suits are designed to protect the processors from contamination, not the people wearing them.Intel stopped using this ad campaign around the same time overalls went out of style, but you can still buy BunnyPeople merch at Intel’s online store.Tomorrow, April 19, is the 50th anniversary of Moore’s law…

  • Three Reasons Why Moore’s Law Might Be Doomed

    16 Apr 2015 | 7:24 am
    On April 19, 1965, Gordon Moore published a prediction that would shape the computer industry for the next 50 years: every year the number of transistors that fit on a microchip will double. (A transistor is basically an electric switch that allows a computer chip to make calculations.) In 1975 he revised this rate to every two years. So far Moore has been right. However, many computer scientists and engineers believe that Moore’s prediction has become a self-fulfilling prophesy. The public and the media expect processing power to double every two years, and any computer that does not…
  • Moore and the Microprocessor

    15 Apr 2015 | 7:14 am
    Gordon Moore first published the article containing what would become his namesake law 50 years ago this week. At the time he was serving as research director at Fairchild Semiconductor. Fairchild had pioneered the development of the modern microchip, which replaced the discrete components used in earlier electronic equipment with a single piece of silicon chemically etched with multiple transistors. As head of R&D, Moore oversaw Fairchild’s push to reduce the size—and increase the quantity—of transistors on each chip. His familiarity with the technical issues associated with these…

    Neutrinos are a type of particle that pass through just about everything in their path from even the most distant regions of the universe. The Earth is constantly bombarded by billions of neutrinos, which zip right through the entire globe, houses, animals, people - everything. Only very rarely do they react with matter, but the giant IceCube experiment at the South Pole can detect when there is a collision between neutrinos and atoms in the ice using a network of detectors. New research results from the Niels Bohr Institute among others have measured the neutrinos at the South Pole and have…

  • Scientists Track Toxicity Of Lake Erie Algae

    Hydrogen peroxide is something that many of us keep in our home medicine cabinets, but the common disinfectant plays a different role in lake ecosystems. It’s produced by the interaction between sunlight and organic carbon in surface waters. In Lake Erie, scientists at the University of Michigan suspect that it may play a hand in making cyanobacteria blooms more toxic, according to a release from the school. But they don’t yet have definitive proof. Researchers at the university were involved in sampling efforts days before high levels of toxic cyanobacteria made water unfit to drink for…
  • Drought Ups Lake Tahoe Clarity

    9 Apr 2015 | 6:44 am
    Water clarity measurements at Lake Tahoe have shown their biggest improvements in more than 10 years, according to a release from the University of California, Davis. But the news is shaded by ongoing drought conditions in the state. After measuring Tahoe’s clarity with Secchi disks, scientists at the UC Davis Tahoe Environmental Research Center and Tahoe Regional Planning Agency report that the lake’s average annual clarity for 2014 was 77.8 feet. The clarity level is a 7.5-foot increase in average annual clarity over the previous year, and nearly 14 feet clearer than Lake Tahoe was in…

    Following the nearly complete ice cover of the last two winters and lowered fall evaporation rates that came with that, the Great Lakes have rebounded to unexpectedly high levels. Lake Michigan-Huron alone is 20 inches higher than it was in 2014, according to a weekly report from the U.S. Army Corps of Engineers Detroit District. The higher levels have already surprised many who work on the Great Lakes, including one boat captain who says he’s never seen water levels so high, according to the Detroit Free Press. And tour groups who survey Muskegon Lake from a Grand Valley State University…

  • when no one really knows if you broke the law

    Greg Fish
    18 Apr 2015 | 11:10 am
    Ignorance of the law is no excuse we’re told when we try to defend ourselves by saying that we had no idea that a law existed or worked the way it did after getting busted. But what if not even the courts actually know if you broke a law or not, or the law is just so vague or based on such erroneous ideas of what’s actually being talked about, that your punishment, if you would even be sentenced to one, is guaranteed to be more or less arbitrary? This is what an article over at the Atlantic about two cases taken on by the Supreme Court dives into, asking if there will be a…

    Greg Fish

    By now, we’ve all heard that Mars One is a basically a scam. Well, maybe not a scam by intent, because it seems like the people behind it really did want to do something amazing and start a genuine Martian colony, but got caught up in their own hubris and are now desperately trying to salvage whatever’s left of their original mission. They don’t want to admit defeat after spending hundreds of thousands of dollars trying to figure out how to get to Mars, but the more they try to salvage their organization, they deeper of a hole they dig. But just because those of us who did…

    Since I’ve been quiet for a long time and a whole lot of things have happened, there’s a sense that before moving forward, we might want to take a quick look back and address a few major issues that have been brewing in atheist and skeptical blogospheres. Sadly, the muddled focus for the future of organized skepticism is still as much a problem as it was over a year ago. It’s unnervingly telling that columns about JREF have been drying up and there’s still no articulated vision for where we go from debunking homeopathy and UFOs, though it would be unfair not to…

He’s been trying to figure out how to do it for many years, publishing a paper detailing how he sees the procedure could work a bit over a year ago, and making his case to the medical community since then. As of a few days ago, however, his work has exploded into the mainstream because there is a public volunteer for this radical surgery, Valery Spiridonov, a Russian programmer suffering from a rare genetic condition which…

    Over the years, this blog took the occasional stab at the way Americans deal with sex, and how downright bipolar the relationship often tends to be. Until the last few years, watching porn was far and away the biggest use of bandwidth on the web, and even now, with social media taking adult entertainment’s crown, it’s still gathering billions of views every week. If anything, we can safely argue that porn has been spilling over into social media as well with the sheer number of sexually explicit content across virtually every social platform, and find a way to show that it still…

    Sports scientist Stephen Dank outside his Ascot Vale home in Melbourne in, 2013. AAP Image/Julian SmithIf Stephen Dank’s NRL life ban is any indication, the controversial sports scientist faces the daunting prospect of never working with AFL footballers again. Dank, who has been found guilty of 10 breaches of the AFL anti-doping code, will receive his penalty when AFL’s anti-doping tribunal sits on May 5. The tribunal found that Dank’s charge of administering Thymosin beta-4 to Essendon players in 2012 could not be proven. This decision followed the clearance of 34 Essendon footballers,…
  • Giant galaxies die from the inside when they stop making stars

    Amanda Bauer, PhD; Astronomer and Outreach Officer at Australian Astronomical Observatory
    16 Apr 2015 | 7:37 pm
    Elliptical galaxies, like this one, are burnt out and no longer making stars. Judy Schmidt and J Blakeslee (Dominion Astrophysical Observatory), CC BY-SAGalaxies are star factories. But for some, such as massive elliptical galaxies, their star-forming days are now over. All of their available gas has already been turned into more than a hundred billion stars. Collectively, these galaxies contain about half of all the stars that have ever existed in the universe. In a new study, published in Science, astronomers have tracked down how the fire of star formation burnt out within these galaxies.
  • Brainy bones: the hidden complexity inside your skeleton

    Pascal Buenzli, Lecturer in Applied Mathematics at Monash University

    Your bones are cleverer, and more complex, than you might think. Michael Dorausch, CC BY-SAYour bones are savvy. They are light yet strong and they repair themselves when they break. What’s more – although you can’t tell – your bones continually renew themselves, replacing old bone for new. This isn’t unique. Other tissues and cells (most noticeably skin) replace themselves. But bones do it with adaptation, adjusting to meet the body’s mechanical and physiological needs. How does the skeleton achieve something so remarkable?

    David Bradley

    When we’re in our teens, it’s common that we first discover the music we see as our own, discarding the vinyl our parents played, and kicking back on beats to our own tune. For me it was a migration from 60s pop to 70s prog and hard rock. But, when you get to middle age you might find yourself living in some kind of shack and you may ask yourself, well what do I listen to now, as you let the days go by?

The accompanying video, much parodied and pastiched, was popular on teh interwebz and was apparently all about raising body image awareness and itself a pardoy of the modern pop culture in which certain characteristics of the female and male form are emphasised in a modern grotesque.. Anyway, in the spirit of scientific endeavour I did a quick frequency analysis of the song to ascertain whether it really was “all about the bass”. And, guess what?

The same cannot be said about fish from the ocean's twilight zone, 200-500 feet beneath the surface. Fish in this region are subject to pressure changes when brought up from their deep water home, which can result in injury or death. Scientists at the California Academy of Sciences were eager to find a way to collect these fish without causing any harm. They needed a decompression chamber that they could bring with them on their dives and use to transport the fish. The only…

Scientists at the University of Cambridge used stem cells derived from the skin of patients with cystic fibrosis – a lung disorder that triggers excessive mucus secretions – and successfully created the distal section of a lung. “In a sense, what we’ve created are mini-lungs. While they only represent the distal part of lung tissue, they are grown from human cells and so can be more reliable than using traditional animal models, such as mice.

    Electronic lab notebooks (ELNs) were created to solve a number of limitations that scientists face when using traditional paper notebooks to track the progress of their research. Due to a variety of reasons, there hasn't been a signifcant adoption of eNotebooks (ELNS) in academic or government labs. On the other hand, about 1/3rd of the biopharmaceutical industry has reported that it has adopted the electronic notebook as its method for recording and maintaining data. Here we talk about why. Though the familiarity of paper lab notebooks makes them attractive to scientists, many other reported…

They were the tiniest, indivisible units possible. Today, of course, we know that they’re not the solid billiard balls they were once believed to be. They have complex innards. Inside, each atom has a nucleus, which, again, is made of neutrons and protons. And around this tight core, energetic electrons, one or more, zip around in concentric orbits. The matryoshka doll-like nesting structure continues on. Neutrons and protons, in…

  • Fact vs Factoid

    Anupum Pant
    17 Apr 2015 | 10:35 am
    By Anupum Pant Fact is something that’s unquestionably true. A universal truth that can’t be denied. Like, the sun rises from the east. Factoid, like a duckling, seems to be like a quick fact. It isn’t. It’s important to remember that it is very different from a fact. A factoid is something that’s repeatedly used wrong at many places. It is a word that is believed to have been coined in the biography of Marilyn Monroe, by Norman Mailer. As the Guardian puts it… A true factoid should sound credible, and be assumed to be true by a significant…

Both the sides have exactly the same kind of beakers and both the beakers have been filled by exactly the same kind of water, to exactly the same level. The balance is still balanced. Now, the balance is clamped to the balanced position and the following is done: One beaker’s base is tethered to a ping-pong ball which is completely inside the water. The other beaker, on the right has an acryllic ball of the same size,…

    By Anupum Pant In a part of Poland there’s a forest called the crooked forest which has about four hundred pine trees which grow with their bases crooked at about 90 degrees. These pine trees are surrounded by several other pine trees which grow fine. There have been several theories about what might have caused the weird bent in only about 400 of these trees. Some seem bizarre, others seem quite plausible. But there’s not a single one which absolutely explains the whole phenomenon.   [Unusual places] The post The Crooked Forest appeared first on AweSci - Science Everyday.

    By Anupum Pant To make a simple electric train you just need a very long copper wire, a pencil cell and a few magnets. Making the train itself is as simple as sticking the magnets at both the ends of the cell. The track is the wound copper wire with an internal radius that is just enough to fit the “train”. If you make it into a loop and send in your train, it just keeps running till the cell runs out. The post World’s Simplest Electric Train appeared first on AweSci - Science Everyday.

    Artificial intelligence research using neural networks has taken off, with a $400-million boost from Google, in part thanks to Canadian Geoffrey Hinton.

    Troy Oakes

    In a new report, scientists have warned that there is a probability of 5 to 10 per cent of a significant volcanic eruption occurring. Experts from the European Science Foundation have said that such an eruption would be massive enough to cause large numbers of deaths. An eruption of this scale would alter the climate, as well as poison the atmosphere. Scientists believe such a scenario will play out by the end of this century. The ash cloud of an eruption of this size would be thrown more than 26 miles (43km) into the atmosphere. The summer that followed the Tambora…

Concussions are a big problem especially in professional sports. Today, diagnosing a concussions involves subjective measures, like cognition tests. A more precise way to diagnose the condition could simplify the diagnosing and help avoid further brain injuries. Earlier studies have found substances that indicate the seriousness of a concussion, but haven’t found a way to diagnose the condition. A new study from Brown…

  • Faraday Cage

    12 Apr 2015 | 8:00 pm
    What I’ve Learned: “Faraday cage: If you can’t keep your wavelength in your pants, keep it in your Faraday.” They say too much of anything can be bad. Sunshine. Children. Tribbles. Jalapeno chili dogs, probably, though I frankly can’t imagine how. Too much electromagnetic radiation can be a problem, too. Whether in the form of a devastating lightning strike, a searing high-voltage current or dangerously delicious microwaves, some sorts of electricity you don’t want zapping through you. Because it might sting. Or leave a hole. When you need to avoid…
  • Mitochondrial Eve

    5 Apr 2015 | 8:52 pm
    What I’ve Learned: “Mitochondrial Eve: Making DNA from an ooooooold family recipe.” Imagine your DNA is a brown bag lunch. Your parents packed it with everything you need. A banana, if you like those. PB&J, maybe — unless your particular DNA makes you allergic to peanuts, in which case, I don’t know. Pizza? Fish heads? Who am I, Andrew freaking Zimmern? The point is, your DNA comes from both your parents, in more or less equal amounts, and it’s stored in each of your body’s cells in something called a nucleus. That’s the bag in this…

    What I’ve Learned: “Orbital decay: Life’s a drag, and then you burn. Or worse.” Gravity is scary. Like, horror movie monster scary. Think about it; gravity is relentless. Just when you think you’ve lost it, there’s gravity behind you, shaking its chainsaw or hockey mask or Lee Press-On fingerblades at you. And it’s sneaky; even if you make it to the abandoned cabin where the lights don’t work and the caretaker killed a busload of nuns exactly fifty years ago tonight, gravity will be inside, lurking in the shadows. You can hide under the covers,…

  • Scientific Data Visualization: A Revolution in Standby

    Mario Barbatti
    11 Apr 2015 | 11:28 pm
    Data visualization in science is at the edge of a revolution. But it depends on scientists, editors, and publishers to take the next step. Next week I’ll be in Berlin speaking about data visualization in science in an interdisciplinary workshop. I’ve been invited to this event due to my experience developing Newton-X . To speak about data visualization will be a challenge for me, as l am no specialist on this field. Data visualization is something l do intuitively as a side aspect of my work. Nonetheless, it’s not insignificant. On the contrary, in some ways it’s a…

  • An Epistemic Search for the True Carbonara

    Mario Barbatti
    29 Mar 2015 | 12:15 am
    People often speak of the “True Italian Carbonara” (or “True Pizza”, or whatever). Does such claim about an ideal dish make sense? Is it possible to establish objective criteria to define the original version of anything? As anyone, every time I’m tired or stressed after an especially long working day, I look for some comfort food. Spaghetti carbonara is one of my favorite of such comforting dishes. Hearty and easy to prepare. Beautiful and affordable. Delicious and relaxing. I have had carbonara everywhere. From a trattoria in Rome to a Mexican in Vienna. From a fine…
  • Is Global Warming a Delicious Nightmare?

    Isadora, my newborn niece, is one of the heirs of the world we’re making right now. The best action against the global warming is doing nothing. The next generations will just thank us for not messing their world up. Have you ever wondered about how difficult and costly it is to do what we believe is right? This is specially hard if we are talking about public policies. Recently, l attended a talk by an IPCC director. He discussed the risks and costs of fighting global warming with a dramatic hypothetical scenario: India and China are the countries contributing the most for emissions…
  • Stop Asking for Letters of Recommendation

    7 Mar 2015 | 11:55 pm
    Manimekhala would probably give Phra Mahachanok a good letter of recommendation. We can’t say the same about the other poor bastards lost to the sea. A letter of recommendation is one of the most useless, costly, and biased instruments for selecting academic staff. Why do we still insist on asking for it? Every time that a call for PhD, postdoc or any other junior position brings a request like “…interested candidates should arrange for two or three letters of recommendation…,” it puts in motion a crazy bureaucratic machine involving a lot of people —…

  • Platinum Investment Casting, Part II: Alloy Optimisation by Thermodynamic Simulation and Experimental Verification

    Johnson Matthey Technology Review
    26 Mar 2015 | 7:00 am
    Two widely used jewellery investment casting alloys (platinum with 5 wt% ruthenium (Pt-5Ru) and platinum with 5 wt% cobalt (Pt-5Co)) suffer from poor castability and other drawbacks. In this work thermodynamic calculations of alloy properties were employed to optimise the alloy compositions. Segregation behaviour appeared to be important for the melting range. Scheil simulations were used to simulate segregation under typical casting conditions. Based on these simulation results, small additions of Co were found to significantly improve the castability of PtRu. Casting trials proved that…
  • How Good is Your Model?

    Johnson Matthey Technology Review
    26 Mar 2015 | 6:56 am
    Models, which underpin all chemical engineering design work, vary widely in their complexity, ranging from traditional dimensionless number correlations through to modern computer based techniques such as computational fluid dynamics (CFD) and discrete element method (DEM). Industrial users require confidence in a model under the conditions it is to be applied in order to use it for design purposes and this can be a reason for slow acceptance of new techniques. This paper explores the validity of models and their validation using a variety of examples from heat transfer, reaction kinetics as…
  • Platinum Investment Casting, Part I: Simulation and Experimental Study of the Casting Process

    This paper summarises the results of collaborative research on investment casting of widely used platinum alloys (platinum with 5 wt% ruthenium (Pt-5Ru) and platinum with 5 wt% cobalt (Pt-5Co)) for jewellery purposes. To enable the simulation of the casting process, a materials database was developed as a first step. Casting simulation tools based on computational fluid dynamics (CFD) were used to optimise the casting process parameters and develop an improved understanding of their role. Selected casting trials were conducted using industrial tilt and centrifugal casting machines and the…

    Scientists have found dark matter interacting with other dark matter in an entirely new way other than just the force of gravity. This first potential signs of self-interacting dark matter suggests that dark matter may not be completely dark after all. Astronomers used a technique known as gravitational lensing to deduce the location of dark matter and using the MUSE instrument on ESO’s very Large Telescope along with images from the ASA/ESA Hubble Space Telescope which is in orbit, they were able to study simultaneous collision of four other galaxies in a cluster known as Abell 3827,…

  • Scientists Turn Off Genes That Spur Deadly Brain Cancer

    Scientists at Northwestern University have discovered a small RNA molecule known as miR-182 that has the ability to quash cancer-causing genes in mice with glioblastoma mulitforme (GBM), an incurable and deadly type of brain cancer. Unlike standard treatment with chemotherapy drugs that stop cancer cells from reproducing which often results in damage of DNA, the new method implements sperical nucliec acids (SNAS) to safely deliver miR-182 across the blood-brain barrier to reach tumor cells. This way, it stops the expression of several oncogenes that encourage the development of cancerous…
  • Blood Moon Moment: Get a Quick Glimpse Of Lunar Eclipse On Saturday, the Shortest of the Century

    On Saturday, you will be experiencing the shortest lunar eclipse of the century. According to NASA , the eclipse will begin at 4.57 am PDT in San Francisco Bay Area and it will last only 4 minutes and 43 seconds which then will soon turn into dusky red. During a lunar eclipse, the sun, Earth and the moon stay aligned in the sky and when the moon passes slowly behind the shadow of the Earth, the surface of the moon will be completely covered. During this phase, due to refraction caused by Earth’s atmosphere with the sunlight, the lunar surface sometimes is seen as a deep orange-red. This…
