    The aramid-nanofiber membrane is stable at high temperatures and resists igniting, even when subjected to a direct flame. (Joseph Xu, University of Michigan) 28 January 2015. Materials scientists and engineers at University of Michigan designed a new material to better protect lithium-ion batteries from starting fires like the kind on Boeing 787 Dreamliners. The team from the lab of engineering professor Nicholas Kotov published its findings yesterday in the journal Nature Communications (paid subscription required). Kotov and first author Siu-On Tung are principals in the spin-off company…

  • This is how phishing scams trick you

    Patricia Donovan-Buffalo
    30 Jan 2015 | 6:16 am
    After all the warnings, how do people still fall for email “phishing” scams? New research shows how certain strategies on the part of the scammers can affect recipients’ thinking and increase their chances of falling victim. “Information-rich” emails include graphics, logos, and other brand markers that communicate authenticity, says study coauthor Arun Vishwanath, professor of communication at the University at Buffalo. “In addition,” he says, “the text is carefully framed to sound personal, arrest attention, and invoke fear. It often will…
  • Is this kid too young for football?

    Barbara Moran-Boston University
    30 Jan 2015 | 6:03 am
    As the 100 million viewers tuning in to this Sunday’s Super Bowl can attest, Americans adore football. And for many, the love affair begins in childhood. But a new study points to a possible increased risk of cognitive impairment from playing youth football. Researchers from Boston University School of Medicine found that former National Football League (NFL) players who participated in tackle football before the age of 12 are more likely to have memory and thinking problems as adults. The study contradicts conventional wisdom that children’s more plastic brains might recover from…
  • Globalization’s first wave wasn’t all positive

    30 Jan 2015 | 5:21 am
    150 years ago, the steamship made international trade possible for many countries. Only a few countries benefited from this first wave of globalization, however. Most ended up worse-off, according to a new study. This is proof that international trade doesn’t automatically lead to economic prosperity, says Luigi Pascali, a professor of economics in the Centre for Competitive Advantage in the Global Economy (CAGE) at the University of Warwick. Until the mid-1800s, the distribution of goods around the world was determined by sailing vessels, which relied on global wind patterns to get from…
  • ‘Parasitic’ genes let mammals evolve pregnancy

    Kevin Jiang-U. Chicago
    30 Jan 2015 | 5:18 am
    Transposons, also called “jumping genes,” were a key part of the evolution of pregnancy among mammals, report scientists. They found thousands of genes that evolved to be expressed in the uterus in early mammals, including many that are important for maternal-fetal communication and suppression of the immune system. “…I guess we owe the evolution of pregnancy to what are effectively genomic parasites” Surprisingly, these genes appear to have been recruited and repurposed from other tissue types by transposons—ancient mobile genetic elements sometimes thought of…

    By creating the first mouse model of aggressive ovarian cancer, researchers say they may have uncovered a better way to diagnose and treat it. “It’s an extremely aggressive model of the disease, which is how this form of ovarian cancer presents in women,” says study leader Terry Magnuson, a professor and chair of genetics at the UNC School of Medicine. Magnuson’s team discovered how two genes interact to trigger the cancer and then spur on its development. Not all mouse models of human diseases provide accurate depictions of the human condition.

    The process of converting the sun's energy into liquid fuels requires a sophisticated, interrelated series of choices but a solar refinery is especially tricky to map out because the designs involve newly developed or experimental technologies.

  • Optically Getting To The Same Side: How To Generating Möbius Strips Of Light

    News Staff
    29 Jan 2015 | 2:48 pm
    A collaboration of researchers have experimentally produced Möbius strips from the polarization of light, confirming a theoretical prediction that it is possible for light's electromagnetic field to assume this peculiar shape. Möbius strips are easy to create, of course. Millions of school children do it in classrooms every year by taking a strip of paper, twisting it once and joining up the ends. That's it, you have created a Möbius strip: a three dimensional structure that has only one side. But finding Möbius strips occurring naturally is another issue. read more

They may be as effective as the ads you're really watching, such as those during the Super Bowl, says a University of Illinois researcher.

  • Extended Telomeres Slow Cell Aging

    News Staff
    29 Jan 2015 | 12:27 pm
    Will extending telomeres lead to longer, healthier lives? Researchers have taken a step toward answering this question by developing a new treatment used in the laboratory that extends telomeres. One of the key aspects of aging is the shortening of telomeres over time. Telomeres, which serve as protective "end caps" for chromosomes, help keep DNA healthy and functioning as it replicates. Unfortunately, these protective end caps become shorter with each DNA replication, and eventually are no longer able to protect DNA from sustaining damage and mutations. In other words, we get older. read…

    Charles Darwin’s IBM computers There are lots of quotes around attributed to the great and the good throughout the years, but often these are anything but direct quotes and in some cases turn out to have far more intriguing origins. For example, the quote often attributed to Thomas John Watson, Sr. (1874–1956) who was chairman and CEO of International Business Machines (IBM) in 1943 had him as saying: “I think there is a world market for maybe five computers.” There are no recorded speeches nor documents that providence evidence for this as a quote from Watson.

  • Sunrise still later after Winter Solstice

    David Bradley
    21 Dec 2014 | 2:00 am
    Several people asked me about the odd phenomenon that in these here parts sunrise gets later each day until early January even though the days themselves get longer after the winter solstice. From EarthSky: The winter solstice always brings the shortest day to the Northern Hemisphere and the longest day to the Southern Hemisphere. But, the tardiest sunrise doesn’t coincide with the day on which the sun is above the horizon for the shortest time, least daylight hours; similarly, the latest sunsets don’t happen on the day of greatest daylight. Why is this? The main reason is that the…

But, could whether news is good or bad be self-perpetuating, particularly in terms of business and financial news?

    I’ve written a review of legendary playwright Tom Stoppard’s new play The Hard Problem at the National Theatre, where he tackles neuroscience and consciousness – or at least thinks he does. The review is in The Psychologist and covers the themes running through Stoppard’s new work and how they combine with the subtly misfiring conceptualisation of cognitive science: This is a typical and often pedantic criticism of plays about technical subjects but in Stoppard’s case, the work is primarily about what defines us as human, in light of the science of human nature, and…

    Despite the news reports, researchers probably haven’t discovered a mention of ‘PTSD’ from 1300BC Mesopotamia. The claim is likely due to a rather rough interpretation of Ancient Babylonian texts but it also reflects a curious interest in trying to find modern psychiatric diagnoses in the past, which tells us more about our own clinical insecurities than the psychology of the ancient world. The claim comes from a new article published in Early Science and Medicine and it turns out there’s a pdf of the article available online if you want to read it in full. The authors…

    by Szu-Chieh Mei, Charles Brenner In laboratory yeast strains with Sir2 and Fob1 function, wild-type NAD salvage is required for calorie restriction (CR) to extend replicative lifespan. CR does not significantly alter steady state levels of intracellular NAD metabolites. However, levels of Sir2 and Pnc1, two enzymes that sequentially convert NAD to nicotinic acid (NA), are up-regulated during CR. To test whether factors such as NA might be exported by glucose-restricted mother cells to survive later generations, we developed a replicative longevity paradigm in which mother cells are moved…

Here we developed a sensorimotor control model that explains vertebrate flight guidance with high fidelity. This simple model accurately reconstructed complex trajectories of bats flying in the dark. The model implies that in order to apply appropriate motor commands, bats have to estimate not only the angle-to-target, as was previously assumed, but also…

When offered two different sugars as carbon sources, microorganisms first consume the preferred sugar, then undergo a transient growth delay, the “diauxic lag,” while inducing genes to metabolize the less preferred sugar. This delay is commonly assumed to be an inevitable consequence of selection to maximize use of the preferred sugar. Contrary to this view, we…
  • Population Diversification in a Yeast Metabolic Program Promotes Anticipation of Environmental Shifts

    Ophelia S. Venturelli et al.
    27 Jan 2015 | 2:00 pm
    by Ophelia S. Venturelli, Ignacio Zuleta, Richard M. Murray, Hana El-Samad Delineating the strategies by which cells contend with combinatorial changing environments is crucial for understanding cellular regulatory organization. When presented with two carbon sources, microorganisms first consume the carbon substrate that supports the highest growth rate (e.g., glucose) and then switch to the secondary carbon source (e.g., galactose), a paradigm known as the Monod model. Sequential sugar utilization has been attributed to transcriptional repression of the secondary metabolic pathway, followed…
  • Illegal Drugs Laws: Clearing a 50-Year-Old Obstacle to Research

    David Nutt
    27 Jan 2015 | 2:00 pm
    by David Nutt The United Nations drug control conventions of 1960 and 1971 and later additions have inadvertently resulted in perhaps the greatest restrictions of medical and life sciences research. These conventions now need to be revised to allow neuroscience to progress unimpeded and to assist in the innovation of treatments for brain disorders. In the meantime, local changes, such as the United Kingdom moving cannabis from Schedule 1 to Schedule 2, should be implemented to allow medical research to develop appropriately.

  • Computation in Dynamically Bounded Asymmetric Systems

    Ueli Rutishauser et al.
    24 Jan 2015 | 2:00 pm
    by Ueli Rutishauser, Jean-Jacques Slotine, Rodney Douglas Previous explanations of computations performed by recurrent networks have focused on symmetrically connected saturating neurons and their convergence toward attractors. Here we analyze the behavior of asymmetrical connected networks of linear threshold neurons, whose positive response is unbounded. We show that, for a wide range of parameters, this asymmetry brings interesting and computationally useful dynamical properties. When driven by input, the network explores potential solutions through highly unstable ‘expansion’…

    by Helen L. Ramsden, Gülşen Sürmeli, Steven G. McDonagh, Matthew F. Nolan Neural circuits in the medial entorhinal cortex (MEC) encode an animal’s position and orientation in space. Within the MEC spatial representations, including grid and directional firing fields, have a laminar and dorsoventral organization that corresponds to a similar topography of neuronal connectivity and cellular properties. Yet, in part due to the challenges of integrating anatomical data at the resolution of cortical layers and borders, we know little about the molecular components underlying this…

    Lynn Roy et al.
    29 Jan 2015 | 2:00 pm
    by Lynn Roy, Emmanuel Bikorimana, Danica Lapid, Hyewon Choi, Tan Nguyen, Richard Dahl Overexpression of miRNA, miR-24, in mouse hematopoietic progenitors increases monocytic/ granulocytic differentiation and inhibits B cell development. To determine if endogenous miR-24 is required for hematopoiesis, we antagonized miR-24 in mouse embryonic stem cells (ESCs) and performed in vitro differentiations. Suppression of miR-24 resulted in an inability to produce blood and hematopoietic progenitors (HPCs) from ESCs. The phenotype is not a general defect in mesoderm production since we observe…

    by Purbani Chakrabarti, Sourav Kolay, Shweta Yadav, Kamalesh Kumari, Amit Nair, Deepti Trivedi, Padinjat Raghu Multiple PIP2 dependent molecular processes including receptor activated phospholipase C activity occur at the neuronal plasma membranes, yet levels of this lipid at the plasma membrane are remarkably stable. Although the existence of unique pools of PIP2 supporting these events has been proposed, the mechanism by which they are generated is unclear. In Drosophila photoreceptors, the hydrolysis of PIP2 by G-protein coupled phospholipase C activity is essential for sensory…

    29 Jan 2015 | 2:00 pm
    by Ted W. Cranford, Petr Krysl Hearing mechanisms in baleen whales (Mysticeti) are essentially unknown but their vocalization frequencies overlap with anthropogenic sound sources. Synthetic audiograms were generated for a fin whale by applying finite element modeling tools to X-ray computed tomography (CT) scans. We CT scanned the head of a small fin whale (Balaenoptera physalus) in a scanner designed for solid-fuel rocket motors. Our computer (finite element) modeling toolkit allowed us to visualize what occurs when sounds interact with the anatomic geometry of the whale’s head.

    It is Holocaust Memorial Day – 27th January. 70 years since the Soviet liberation of the Nazi concentration camp Auschwitz-Birkenau. The word “holocaust” has become synonymous with the genocide of millions under the Third Reich. The etymology of the word itself is interesting. From etymonline.com: In the mid-13th Century, holocaust meant to “sacrifice by fire”, it was a “burnt offering”. The word coming from the Greek holokauston “a thing wholly burnt,” in turn from holos meaning the “whole” and kaustos, the adjectival form of…

    Nathan Yau
    29 Jan 2015 | 11:17 am
    It's a common belief that if someone has a medical condition, a patient can take a treatment and the condition gets better or goes away. That is, improvement is directly related to intake. However, as it turns out, there's often a good chance the patient would have gotten better without the treatment. There's also a chance a treatment does nothing. Austin Frakt and Aaron E. Carroll for the Upshot describe these chances through a metric called number needed to treat, or N.N.T. The simple animations throughout the article provide a great dose of perspective to the odds.

    A data-centric look at New England Patriots fumble rates at home made the rounds this week.

    Birds cross Himalayas A bar-headed goose on the wing. Photo: Nyambayar Batbayar When bar-headed geese migrate across the spine of the Himalayas, they follow the terrain, roller-coaster style, rather than fly a straight-line path from ridge to ridge. This flight path features far more climbing, yet a study published today in Science shows that it’s considerably more efficient than the straight-line course. To look at how these geese make the long, high-altitude flight between India and Mongolia, Charles Bishop, a senior lecturer at the University of Bangor in the United Kingdom, and a…

On Dec. 3, demonstrations broke out after a grand jury declined to prosecute the officers. Then, on Dec. 20, two police officers were murdered in their car by a 28-year-old with a long criminal record as vengeance for Garner’s death. At the funerals, police have turned their backs on Mayor Bill de Blasio. The death of Michael Brown, 18, from police…

  • Egyptian statuettes of Osiris: Production unveiled by neutrons and laser

    30 Jan 2015 | 7:40 am
    The world's museums exhibit collections of precious artefacts from thousands of years ago. Very often it is the case that not much is known about how those ancient artefacts were created. There is a number of limitations to investigate them as traditional sampling techniques risk damaging the materials. In the search for non-invasive methods, a group of scientists have combined three different techniques to analyse copper alloy figurines. They wanted to know how the figurines were crafted, their composition, and how they are deteriorating.
  • Super Bowl athletes are scientists at work

    30 Jan 2015 | 7:30 am
    Seattle Seahawks cornerback Richard Sherman gets called a lot of things. He calls himself the greatest cornerback in the NFL (and Seattle fans tend to agree). Sportswriters and some other players call him a loudmouth and a showboater. Fans of other teams call him a lot of things that shouldn't see print (even on the internet). One thing you're not likely to hear anyone on ESPN call Sherman, though, is "scientist."

    Five new species of tiny, shimmering spiders have been discovered in Madagascar, according to a new study. In the study, researchers looked at 326 spider specimens they had previously collected in Madagascar over the course of a few years. "It is a remarkable discovery — a genus comprising a number of species previously unknown to science, unknown to the world," said study author Charles E. Griswold, curator of arachnology at California Academy of Sciences in San Francisco. One of the features that distinguishes the members of the new genus from other goblin spiders is the glistening…
  • Could Super Bowl Outcome Be Influenced By Biological Clocks?

    Football fans, take note: The outcome of this weekend's Super Bowl, along with other major sporting events, may depend on whether the players are night owls or early birds, a new study suggests. "Even 1 percent makes the difference between winning a race and losing it," said Roland Brandstaetter, a biologist at the University of Birmingham in England and co-author of the study published today (Jan. 29) in the journal Current Biology. The findings could have big implications for the timing of major sporting events, and how athletes train for them, the researchers said. Previous studies have…

    In a 2012 episode of the TV series Homeland, Vice President William Walden is assassinated by a terrorist who hacks into his Internet-enabled heart pacemaker and accelerates his heartbeat until he has a heart attack. This scenario is more than just a flight of fancy. Internet security experts have been warning for years that devices such as insulin pumps, glucose monitors, and pacemakers or defibrillators, when connected to the Internet, may be vulnerable to hackers who can take control of a device and change its settings. Manufacturers are starting to wake up to the issue and are employing…
  • [Special Issue News] Privacy: Credit card study blows holes in anonymity

    John Bohannon
    29 Jan 2015 | 4:00 pm
    For social scientists, the age of big data carries big promises: a chance to mine anonymized demographic, financial, medical, and other vast data sets in fine detail to learn how we lead our lives. For privacy advocates, however, the prospect is alarming. They worry that the people represented in such data may not stay anonymous for long. A study of credit card data in this week's issue of Science bears out those fears, showing that it takes only a tiny amount of personal information to de-anonymize people. The result, coming on top of earlier demonstrations that personal identities are easy…

    John Bohannon
    29 Jan 2015 | 4:00 pm
    It's hard for a machine to pluck your face out of a crowd. If you appear in a photo taken at a protest march, an abortion clinic, or a gay bar, for example, your anonymity is safe—for the time being. Unless a computer has been tasked to look for you and it has already trained on dozens of photos of your face—and the quality of the images you appear in is excellent—there is little chance that it will spot you. Nor is it yet possible for a computer to search the Internet for all photos in which your face appears, unless you are named in captions. But within the walled garden of Facebook,…

    Jennifer Couzin-Frankel
    29 Jan 2015 | 4:00 pm
    It's becoming more and more difficult to safeguard the privacy of patients who participate in scientific studies. Many patient samples today are banked, sequenced, and shared with potentially thousands of researchers, and it's widely accepted that if you can read someone's DNA, you may be able to figure out who they are. That's why researchers are seeking new ways of gaining patients' trust and keeping them involved—for instance by giving them more control over how their samples are used or being more transparent about the studies that their data are used in. Some are looking at popular…

    Like a fingerprint or an iris scan, every voice is unique. Security companies have embraced voice recognition—in which a segment of speech is recorded and the frequencies at which the sound is concentrated are analyzed—as a convenient new layer of authentication. Physical and behavioral traits of the speaker create a unique spectral signature, and demand for the technology is now skyrocketing. But experts worry that voiceprints could be used to identify speakers without their consent and compromise their anonymity, infringing on their privacy and freedom of speech. How and when…

  • Six Ways to Measure T Cell Responses

    Olwen Reina
    21 Jan 2015 | 7:00 am
    T cells can be problematic to characterise because they have a wide variety of subtypes and because of the technical difficulties of studying the membrane-bound T cell receptor, but there are situations where you want to be able to do this such as analysing the degree to which immunological memory has been induced to measuring how well an individual mounts a response to a particular antigen. If you do want to study T cell responses, don’t fear! There are various ways to achieve this, and these assays fall into two main categories: those that detect the activation of T cells in response to a…

    The human brain is often described as the most beautiful organism in the Universe. We say this because of the beautiful things the mind, sustained by the brain, can create and imagine. Greg Dunn earned his PhD in Neuroscience at the University of Pennsylvania in 2011, but while his colleagues are fiddling with microscopes to unravel the inner workings of brain cells, he works with a paintbrush to magnify neurons on a canvas. His work shows a brain whose beauty transcends romanticism and awes in its raw form.

    Knowledge is often lost through accident, acts of nature, or obsolescence. Once gone, it’s usually gone forever. But a recent piece in the New York Times offered a rare example of knowledge recovered from natural disaster. Nicholas Wade reports in the Times that the compete destruction of a library in Herculaneum by Mount Vesuvius’s eruption in 79 CE (the same eruption that destroyed Pompeii) may at least be partially undone by modern technology, in this case by X-rays from the European Synchrotron in Grenoble, France. It’s not that the X-rays can undo the damage to the papyrus, which…

Regardless of their value, these objects all have one thing in common: one day they will become trash.

    It’s the big game. You’re running full speed toward the goal line. You have it in sight. You are focused. You are fast. This is it. BAM! You’ve been hit. This is not it. The ball is gone. The moment is passed. And you are on your back. Nothing is broken. But your brain has been rattled. That hit has led to a traumatic brain injury (TBI). TBI happens when a bump, blow, jolt, or other head injury causes damage to the brain. Every brain injury, even a concussion, is a TBI. A concussion happens when the brain bumps the skull, causing mild damage, almost like a bruise. Usually a concussion…
  • “I Wish That I Could Be Like The Cool Kids.”

    The NIDA Blog Team
    12 Jan 2015 | 12:00 am
    The popular lyrics hit home for many of us. There probably isn’t a teen out there that at some point hasn’t wanted to be part of the cool crowd.  Just about everyone knows who the cool kids are and gossips about what they do.  Of course, what’s cool in your school may not be cool at a different school in another city or part of the country.  For example, a few years back, one teen, Shelby Marie Raye, won a NIDA Addiction Science Award for her research on what makes kids cool.  In her school, sports were in. Honors classes were out. And drugs and alcohol were less cool the older…
  • Designated Drivers—You Are Not Alone

    The NIDA Blog Team
    8 Jan 2015 | 12:00 am
    A new survey from Mothers Against Drunk Driving (MADD) and Nationwide Insurance found that 3 out of 4 people use designated drivers (DD). The DD is the person who does not drink, use drugs, or even take medication that might impair their driving.  By the way, the DD is NOT the least drunk person in the group---they are the ones who don’t use any drug or alcohol at all at a party or event, even a little bit. Why do they choose DDs? Because they want to get home in one piece.  The MADD survey reveals that 75% of the people who volunteer to be the DD do so because they want to get home…

  • Science for kids - Slime

    14 Jan 2015 | 2:46 am
    Everyone likes slime! And it's easy to make, in its various forms.Cornflour Slime:All you need is cornflour (made from actual corn - maize - not the "wheaten" version you can get in Australia, which is made from wheat), water, some colouring, a bowl and a spoon. The process is: Pour cornflour into a bowl, Stir in small amounts of water until the cornflour becomes a thick paste. I prefer to have the water coloured at this point, as it helps to more effectively spread the colour throughout the slime.And that's it. Try stirring the slime slowly (should be easy) and then quickly (should be almost…

  • Science for kids - detergent powered boats

    9 Jan 2015 | 8:38 pm
    This is an easy one, assuming you occasionally clean your dishes. You just need some bread ties, water and detergent. The video is a little unimpressive, but you could dress the bread ties up to make them look like boats. Essentially, the detergent is breaking the surface tension of the water, and if you break the surface tension behind the bread tie, the tension in front of the tie pulls it forward. Detergents are surfactants, which means they have a polar end (which is attracted to water) and a non-polar end (which is attracted to oil and grease). This is how detergents (and soaps) bond to…
  • Ep 156: Science for kids - home-made lava-lamp

    9 Jan 2015 | 8:14 pm
    This Christmas break, I have been mucking around with science experiments for my kids. Here is the first of a few easy experiments you can try at home.The following videos show you how to make a home-made lava lamp. It is very simple - grab a clear cup (or bottle or vase or flask), fill it about a third full of water and two thirds full of oil. The oil floats on the water as it has a lower density. Add some food colouring (you can do this at the start directly to the water, or after you have added the oil - this has the added benefit of showing that the food colouring does not dissolve in the…

Add a generous amount of colouring to the water (20-odd drops), add the flowers, and wait. It can take longer than a day, especially if you haven't quite added enough colouring, so be patient. Here are some shots we took of our red and blue flowers (I reckon you can be more impressive than this!):The flowers turned blue quicker than red for me, and others have seen similar things (anyone know why?)The science on display is the capillary action of the water - that is, how the…

  • Previously Unknown Window --"May Reveal Existence of Hidden Dark-Matter Particles"

    dailygalaxy.com
    29 Jan 2015 | 7:54 am
    Dark Matter is thought to exist because of its gravitational effects on stars and galaxies, gravitational lensing (the bending of light rays) around these, and through its imprint on the Cosmic Microwave Background (the afterglow of the Big Bang). Researchers at the University of Southampton have proposed a new fundamental particle which could explain why no one has managed to detect 'Dark Matter', the elusive missing 85 per cent of the Universe's mass. Despite compelling indirect evidence and considerable experimental effort, no one has managed to detect Dark Matter directly. Particle…
  • A Quantum View of Space (Yet Another Win for Einstein!)

    dailygalaxy.com

    Ever since Einstein proposed his special theory of relativity in 1905, physics and cosmology have been based on the assumption that space looks the same in all directions -- that it's not squeezed in one direction relative to another. A new experiment by physicists used partially entangled atoms -- identical to the qubits in a quantum computer -- to demonstrate more precisely than ever before that this is true: to one part in a billion billion. The universal quantum computer, first proposed by David Deutsch in 1985, has a marvelous property: it can simulate any physically possible…
  • Extreme Worlds May be Habitable

    Two phenomena known to inhibit the potential habitability of planets -- tidal forces and vigorous stellar activity -- might instead help chances for life on certain planets orbiting low-mass stars by combining to transform uninhabitable "mini-Neptunes" -- big planets in outer orbits with solid cores and thick hydrogen atmospheres -- into closer-in, gas-free, potentially habitable worlds. Most of the stars in our galaxy are low-mass stars, also called M dwarfs. Smaller and dimmer than the sun, with close-in habitable zones, they make good targets for finding and studying potentially habitable…

    28 Jan 2015 | 9:48 am
    "Since the beginning of time, this planet was characterised by intense heat and volcanic activity, which would have evaporated any possible water and made the emergence of life highly unlikely," asserts ETH Zurich geophysicist Giovanni Leone. The two hemispheres of Mars are more different from any other planet in our solar system. Non-volcanic, flat lowlands characterise the northern hemisphere, while highlands punctuated by countless volcanoes extend across the southern hemisphere. Although theories and assumptions about the origin of this so-called and often-discussed Mars dichotomy abound,…

    In an article penned for The Guardian, scientists who have just completed a study covering two years of desiccation to Iran’s Lake Urmia urge action to protect the once ecologically rich water body. While international help is important for bringing the lake back to its old glory – it was once the largest saltwater lake in the Middle East – the bulk of the work will have to be done by Iranians themselves, they say. The recommendations come after the researchers, all of whom are of Iranian descent, found that the lake’s surface area was about 12 percent of its average in the…
  • Two Subglacial Lakes In Greenland Disappear

    With the help of high-resolution satellite images, scientists at Ohio State University have found that two subglacial lakes in the Greenland ice sheet have effectively disappeared, according to Live Science. The loss of the lakes, they say, signals a major shift in the mechanics of the ice sheet that could be linked to broader environmental changes. Researchers at the school made the discovery after large volumes of meltwater, predicted at billions of gallons in quantity, were found flushing to the sea, leaving behind large sunken craters in their wake. One was so large, according to the…
  • Study: Algal Blooms Optimize Conditions To Support Growth

    22 Jan 2015 | 7:18 am
    A study led by scientists at Dartmouth College suggests that reducing algal blooms in U.S. lakes may not be as simple as cutting phosphorus loads from runoff, according to WYSO public radio. Algae, the researchers found, appear to be able to make use of nutrient deposits buried in sediments long ago. Some have tried to explain why lakes with reduced phosphorus inputs, like Minnesota’s Lake of the Woods, can still be experiencing blooms, or even worse – bigger blooms. Warmer temperatures, experts put forth, are making it easier for algae to proliferate. This study, published in the…

This method is accurate in measuring depth. However, its applicability is constrained by high operating cost, inefficiency, and inapplicability to shallow waters (Gao, 2009). Typical bathymetry models which lack data from shallow waters often extrapolate the lake bottom surface to the un-surveyed shores (Figure 1), but suffer from large uncertainties…

    An artist's impression of the oldest known system of terrestrial-sized planets, Kepler-444. Tiago Campante/Peter Devine, University of Birmingham, Author providedOne of the crucial variables in calculating the likelihood that alien life exists elsewhere in our galaxy is the number of stars that possess planetary systems, and the proportion of those planets that might be suitable for life. So the discovery of no less than five sub-Earth-sized exoplanets orbiting an ancient star, Kepler-444, which is not too distant from our own solar system, has significant ramifications for the…

  • Predictive text: Darwin’s computers

    David Bradley

    Charles Darwin’s IBM computers There are lots of quotes around attributed to the great and the good throughout the years, but often these are anything but direct quotes and in some cases turn out to have far more intriguing origins. For example, the quote often attributed to Thomas John Watson, Sr. (1874–1956) who was chairman and CEO of International Business Machines (IBM) in 1943 had him as saying: “I think there is a world market for maybe five computers.” There are no recorded speeches nor documents that providence evidence for this as a quote from Watson. Indeed, the…

  • Sunrise still later after Winter Solstice

    David Bradley
    21 Dec 2014 | 2:00 am
    Several people asked me about the odd phenomenon that in these here parts sunrise gets later each day until early January even though the days themselves get longer after the winter solstice. From EarthSky: The winter solstice always brings the shortest day to the Northern Hemisphere and the longest day to the Southern Hemisphere. But, the tardiest sunrise doesn’t coincide with the day on which the sun is above the horizon for the shortest time, least daylight hours; similarly, the latest sunsets don’t happen on the day of greatest daylight. Why is this? The main reason is that the…
  • No news is good news

    Depending on whether or not you’re a pessimist or an optimist, either the aphorism “no news is good news” holds true or the maxim “all publicity is good publicity” is more accurate. But, could whether news is good or bad be self-perpetuating, particularly in terms of business and financial news? UK researchers have analysed the impact of the financial crisis that began in 2008 by looking at news output in terms of company chair financial statements for the period 2006 to 2010 for financial companies.

    "That's Star Trek stuff!" ... is pretty much the bemused reaction you'll get if you allow yourself to answer casual questions about science over a drink with a non-physicist.  AB-SO-LUTE disbelief.  Your fault!  Shouldn't have gone there...  Pretend you didn't hear the question...  Especially if the answer is ion propulsion!   Stick to the mundane.  Yawn.  Most people only smile at the idea of new technologies.  Some get angry because they think you're having a joke.  Even though you know that it may sounds like SciFi,…

  • The Queen Of Code

    Allison McCann
    28 Jan 2015 | 8:00 am
    You probably don’t know the name Grace Hopper, but you should.As a rear admiral in the U.S. Navy, Hopper worked on the first computer, the Harvard Mark 1. And she headed the team that created the first compiler, which led to the creation of COBOL, a programming language that by the year 2000 accounted for 70 percent of all actively used code. Passing away in 1992, she left behind an inimitable legacy as a brilliant programmer and pioneering woman in male-dominated fields. Hopper’s story is told in “The Queen of Code,” directed by Gillian Jacobs (of “Community”…

    A few weeks ago, I wrote a story on the relationship (or lack thereof) between cellphone use and brain tumors. Afterward, I received a number of emails from men who said, more or less: Forget about the brain tumors. What I really want to know is whether leaving my cellphone in my pocket is affecting my sperm.This is hardly the only sperm-related concern, and there are plenty of rumors about what does and does not affect male fertility. For example, does wearing tight underwear reduce sperm count?I polled some FiveThirtyEight staff members, and some of my friends, about what they’ve…
  • Big Blizzards Have Become More Common In New York

    26 Jan 2015 | 8:28 am
    It’s snowing less in New York, and it’s snowing more. Let me explain.If you read my colleague Harry Enten’s Sunday piece — or if you’ve been living in New York for the past few years — you’ll know that the city has recently endured some awful snowstorms. Of the top 10 snowfalls on record at Central Park dating to 1869, five have occurred since 2003. This week, they could be joined by a blizzard dubbed Winter Storm Juno.So, has New York become snowier? I downloaded Central Park’s daily snowfall totals for the past 100 winters (1914-15 through 2013-14) from the…

    You’re coughing, you’re congested, and your head hurts. You’re achy and feverish, and your throat is killing you. A quick Google search reveals that you probably have the flu. What’s your next move? You could call in sick and quarantine yourself at home while you nurse your symptoms with cough drops, an over-the-counter remedy, chicken soup and a Netflix binge. Or you could go to your doctor and get a prescription for an antiviral influenza drug, something like Tamiflu.The Centers for Disease Control and Prevention recommends the latter approach.The CDC released figures Thursday…

    Photo credit:Marcelo Terraza Microbes have dominated earth’s ecology for at least the past 3.5 billion years. They play a vital role in the planet’s carbon cycle by digesting organic matter. Fecal prints of microbes have the potential to carry vital information such as the planets temperature, greenhouse gas composition and how oxygen levels have changed through time.

    Back in the mid-1980s, I and my family had lived in Uganda for a while, in the very year president Milton Obote was overthrown by a military regime. Caught in the intermittent crossfire between the militia and government forces, we could easily have been hit by whizzing bullets. We were lucky. We were able to make it out of Kampala, the capital, safely, before it fell to the rebels. We’d escaped trouble by a whisker. But after having read Richard Preston’s “The Hot Zone, I began to wonder that dangerous as the coup d’état had been, it was a pathogen that could have proved far…
  • African Soil- The New Future?

    The 2014 Africa Progress Panel report presents the two faces of Africa: robust economic growth and continuing poverty.  The agricultural sector of Africa has always been an asset, with the large space’s to produce crops; agriculture contributes to 60% of all employment of Africa’s Labour force. Yet, because of low productivity the sector accounts for only 25% of the continents gross domestic product (GDP)[1]. However, Africa’s growth has been extremely rapid with Sub-Saharan Africa accounting for a six of the world’s 10 most rapidly growing economies[2]; it seems there is a…

    Back in 2010, the Venter lab announced they had synthesized the entire set of DNA (with some changes) from the bacterium Mycoplasma mycoides in the lab. Even more remarkably, they transplanted this artificial genome into a different species of bacteria, Mycoplasma capricolum, and this bacterium was transformed into Mycoplasma mycoides. They had now essentially created life in the lab. This technology has improved even further seeing many great scientific achievements during 2014,  such as the comet landing in November, the vow against animal poaching, and the redesigning life scheme…
  • Where Was Earth’s Water Born?

    Alakananda Mookerjee
    11 Dec 2014 | 1:02 pm
    Photo:Comet 67/P Copyright:ESA/Rosetta/NAVCAM The question of where all of Earth’s water came from has been a scientific puzzle. It was long presumed that the planet wasn’t born with it, but that it appeared some 700 million years later—likely from comets. But data sent back by Rosetta from comet 67/P refutes that theory, reports The New York Times. The water on it—which exists in the form of ice and vapor—is different from terrestrial water. That water has thrice the concentration of “heavy water” (a form of water in which its hydrogen is replaced by deuterium, a heavier…

That shouldn’t have happened, it wasn’t even a month old, right? Right. If you stumble upon a hamster, especially a Syrian hamster that looks like it has died, it probably hasn’t.

    By Anupum Pant In the past we’ve seen the chocolate pudding fruit. Today, it is the lemonade fruit – A fruit that right off the tree tastes like lemonade. It is a popular tree in  New Zealand and Australia, and is also seen growing in some orchards of the USA. However, it is not very commercially popular yet. A lemonade fruit looks a lot like lemon. That is because it is a cross between a navel orange and a lemon, first grown fairly recently, in the 80s. When ripe, it turns yellowish and is nicely segmented inside. Also, they have soft skins and can be peeled with great ease.

    By Anupum Pant Take a glossy black ceramic bowl and fill it with water. Now place it in the middle of a rotating wheel. What do you get? Thanks to the complex play of centrifugal forces creating a gradient of forces as the function of radius, with earth’s gravity also doing its part, you get a parabolic shaped water surface. If this liquid you use is a liquid metal like mercury, or Gallium (at slightly higher temperatures), you’d have a parabolic mirror in a bowl. Depending on the speed of your rotation, you can adjust the focal length of the mirror. That’s because the…

The number of drugs that make a lethal combination with grapefruit was only 17 till a few years back, but the number is rapidly rising. In 2012 the number went up to 43. Taking in these 43 drugs with a glass full of grapefruit juice can all have some serious side effects – ranging from stomach bleeds, altered heart beat,…

  • Earth Beasts Awaken – An Interview With Brian Engh

    Brian Switek
    21 Jan 2015 | 7:13 pm
    Part of the fun of dinosaurs is that some of them seem so monstrous. Their skeletons come in all sorts of awesome shapes and sizes, so it’s not terribly surprising that filmmakers have been turning to dinosaurs for inspiration with fictional monsters for decades. (After all, what’s Godzilla but a theropod with Stegosaurus plates and more than a touch of radioactivity about him?) And among all the monsters out there, Brian Engh‘s fossil-inspired creatures for his Earth Beasts Awaken music video series have most recently caught my eye. Brian Engh‘s Earth Beast Awakens…

  • Why Aren’t Mammals as Big as Giant Dinosaurs?

    Brian Switek
    14 Jan 2015 | 11:44 am
    Not all dinosaurs were giants, but, all the same, their ranks included the largest animals ever to walk the Earth. Supersaurus, Argentinosaurus, Futalognkosaurus, and more – these huge sauropod dinosaurs stretched over 100 feet long and weighed upwards of 45 tons, depending on the species. ‘Stormy Clouds, New Horizons’ by Mark Witton No land-dwelling mammal has ever gotten close to such sizes. The biggest – a hornless rhino named Paraceratherium – was about 25 feet long and topped out around 20 tons. Why should this be so? Have mammals not evolved to the full…
  • Alaska’s Dinosaurs Went With the Flow

    Brian Switek
    8 Jan 2015 | 3:07 pm
    Dinosaurs got buried in all sorts of ways. Their bodies were covered by lake sediment, engulfed by quicksand, encrusted by marine life, and more. But one of the most spectacular burials of all took place in the Cretaceous high Arctic, where scores of juvenile dinosaurs were buried together. A diagram of a mass dinosaur burial in Alaska, showing layers of plants and bones that spilled over the prehistoric floodplain. From Flaig et al, 2014. University of Texas geologist Peter Flaig and colleagues have laid out what happened in a new PALAIOS paper. Around 69 million years ago, on land now…

    ByThe Toombst Bacteria, either our best friend or our worst enemy. New research finds that it might be possible to treat diabetes using modified probiotic bacteria. Diabetes, a disease that makes you unable to control your blood sugar. This is caused by either the destruction of cells producing the hormone insulin or a gradual loss of sensitivity to this hormone. Both of these forms of diabetes can be treated with different pharmaceuticals or lifestyle changes. Treating the disease with drugs, like insulin injections, can’t match the precision of the body’s own blood sugar…
  • A New Way to Kill Multidrug-Resistant Bacteria

    28 Jan 2015 | 10:45 pm
    ByThe Toombst The time of multidrug-resistant super-bacteria might be coming to an end. New research have found a small protein in viral toxin-resistant bacteria that can kill multidrug-resistant bacteria. Using antibiotics breeds resistance by introducing a so-called selection marker into a population of bacteria. This is bad news for us since we’ve become dependent on being able to kill disease-causing bacteria in the last 60 years. Until very recently finding new effective antibiotics seemed like a pipe dream. Other ways to combat resistance is needed to defeat the threat posed by…
  • Violent Psychopaths’ Brains are unable to understand Punishment

    ByThe Toombst A new study using MRI scans to investigate violent psychopaths’ brains find that abnormalities in their brains prevent them from learning from punishments, adjusting their behavior. Psychopaths, or people with a psychopathic disorder, are people that differ from the rest of us by displaying antisocial behavior, a reduced ability for empathy and lacking inhibitions. This disorder doesn’t automatically mean violence, but previous studies have shown that violence are more likely to come from people who have this disorder. New research from University of Montreal suggest…

    What I’ve Learned: “Tumor suppressor: I’m no hero; I’m just doing my job.” Fighting evil isn’t all it’s cracked up to be. First of all, it’s hard. Evil is basically everywhere outside of Walt Disney World, so there’s always another battle on hand. Also, evil is fiendishly creative. Just when you think you have it in check, it’ll pop up behind you, tenting its fingers and snarling, “Excellent.” But the worst part about fighting evil is that you’ll never be recognized for anything else. That must get old for heroes.

Meaning, that’s the first solar system object humans knew about, mostly because we kept tripping and falling face-first onto it. Early humans weren’t particularly coordinated. The sun was also pretty hard to miss, what with the light and heat and occasional scary eclipses. By the 2nd century B.C., eagle-eyed up-gazers had also spotted Mercury, Venus, Mars, Jupiter and Saturn. Not bad for people who didn’t have a…

  • The Crooked Lines of Mr. Newton

    Mario Barbatti
    25 Jan 2015 | 12:07 am
    Newton created his mechanics as something between an anti-atheist manifest and a treat of theology. Poor Sir Isaac, he had no idea he was gifting civilization with a major contribution to a godless world. Most of people think of space as an empty volume where things stand. Take all things out, the space would still be there. René Descartes wasn’t most of people. For him, space was only a relation between things, with no existence whatsoever. Thus, motion is always relative, as there is no absolute space framing the world. Moreover, Descartes believed that the universe was composed of…
  • The Science of “The End and the Life”

    Mario Barbatti
    10 Jan 2015 | 11:25 pm
    In the last post, I wrote a short fictional dialogue, where two colleagues, Edwin and Friedrich, discussed possible scenarios for the future of the universe. In this post, I want to come back to that topic to explore a bit of the science behind those ideas. 1. Cyclic Universe and Eternal Return The first scenario, proposed by Friedrich, was a cyclic universe with eternal return. Eternal return was a relatively popular concept in the 19th century. We find Nietzsche, Boltzmann, Poincaré, and other less shinning names–Dühring, Blanqui, Le Bon, Heine–speculating about it. The idea…

    Expanding universe, eternal return? Here it is my (short) fictional take on these speculative dreams. “Past time is finite, future time is infinite.” E. Hubble. “Everything has returned: Sirius and the spider, and your thoughts at this hour, and your thought that everything returns.” F. Nietzsche. He didn’t wait for the answer, the conclusion drew itself obvious to him. He said: “If the universe collapses, then it wouldn’t have time to give birth to your wonderful semi-eternal beings. If, in addition, the universe evolves through recurring cycles of…

Then, I moved to Europe over one decade ago and everything changed. It’s September or October when we start to notice that the days are getting shorter, nights longer. By the end of December we just worship the few remaining hours of light. We fell like Calvin: I learned that there is a whole psychology connected to this season’s change.
