  • Lasers show how Sea Monkeys mix oceans

    Marcus Woo-Caltech
    30 Sep 2014 | 12:13 pm
    Even though each “Sea Monkey” is only about half an inch long with 10 tiny, leaf-like fins, they can collectively generate a surprising amount of force. It turns out that the collective swimming motion of Sea Monkeys (brine shrimp) and other zooplankton—swimming plankton—can generate enough swirling flow to potentially influence the circulation of water in oceans, according to a new study. The effect could be as strong as those due to the wind and tides, the main factors that are known to drive the up-and-down mixing of oceans, says John Dabiri, professor of aeronautics and…

  • 5 genes help protect people from severe malaria

    Liz Banks-Anderson-Melbourne
    30 Sep 2014 | 11:56 am
    Scientists analyzed 27 malaria resistance genes and found that five significantly determine how susceptible a person is to severe malaria. The findings could allow researchers to identify new therapeutics or vaccines to fight the disease. For the study, published in Nature Genetics, researchers collected data on 11,890 cases of severe malaria across 12 locations in Africa, Asia, and Oceania, where access to health resources to treat the disease can be difficult. Severe malaria is comprised of a number of life-threatening complications after infection with the malaria parasite. Related…
  • Soliton discovery was a false alarm

    Emily Conover-UChicago
    30 Sep 2014 | 8:02 am
    Physicists say that a group of scientists were incorrect when they concluded that a mysterious effect found in superfluids indicated the presence of solitons—exotic, solitary waves. Instead, they explain, the result was due to more common, whirlpool-like structures in the fluid. Their explanation appears in Physical Review Letters. A soliton wall? The debate began in July 2013, when a group of scientists from the Massachusetts Institute of Technology published results in Nature showing a long-lived structure in a superfluid—a liquid cooled until it flows without friction.

    Scientific studies have detected no differences in the nutritional makeup of foods derived from animals that ate genetically engineered crops, according to a recent review. The review also finds that the performance and health of food-producing animals consuming genetically engineered feed, first introduced 18 years ago, has been comparable to that of animals consuming non-GE feed.

    30 Sep 2014 | 7:52 am
    Scientists say there’s a link between California’s severe drought and global warming. Noah Diffenbaugh, a climate scientist at Stanford University, used a novel combination of computer simulations and statistical techniques to show that a persistent region of high atmospheric pressure hovering over the Pacific Ocean that diverted storms away from California was much more likely to form in the presence of modern greenhouse gas concentrations. The research, published as a supplement to this month’s issue of the Bulletin of the American Meteorological Society, is one of the…

    News Staff
    1 Oct 2014 | 5:30 am
    Transcranial magnetic stimulation (TMS) of the left dorsolateral prefrontal cortex can treat symptoms of depression in humans by placing a relatively small device on a person's scalp and stimulating brain circuits, yet little is known about how TMS produces these beneficial effects. Some studies have suggested that TMS may modulate atypical interactions between two large-scale neuronal networks, the frontoparietal central executive network (CEN) and the medial prefrontal-medial parietal default mode network (DMN). These two functional networks play important roles in emotion regulation and…
  • Ultrasound Elastography: 'Virtual Breast' Could Improve Cancer Detection

    Breast cancer is the second leading cause of cancer death in women, which is why so many medical professionals encourage women to get mammograms. But the tests are not very accurate: only a minority of suspicious mammograms actually leads to a cancer diagnosis. Bad results lead to needless worry for women and their families—not to mention the time, discomfort and expense of additional tests, including ultrasounds and biopsies.  read more

There has been ongoing consternation about the reliability of some psychology research, particularly studies which make claims about unconscious (social) priming.

  • Contact-Mediated Inhibition Between Oligodendrocyte Progenitor Cells and Motor Exit Point Glia Establishes the Spinal Cord Transition Zone

    Cody J. Smith et al.
    30 Sep 2014 | 2:00 pm
    by Cody J. Smith, Angela D. Morris, Taylor G. Welsh, Sarah Kucenas Rapid conduction of action potentials along motor axons requires that oligodendrocytes and Schwann cells myelinate distinct central and peripheral nervous system (CNS and PNS) domains along the same axon. Despite the importance of this arrangement for nervous system function, the mechanisms that establish and maintain this precise glial segregation at the motor exit point (MEP) transition zone are unknown. Using in vivo time-lapse imaging in zebrafish, we observed that prior to myelination, oligodendrocyte progenitor cells…

    by João Francisco Botelho, Luis Ossa-Fuentes, Sergio Soto-Acuña, Daniel Smith-Paredes, Daniel Nuñez-León, Miguel Salinas-Saavedra, Macarena Ruiz-Flores, Alexander O. Vargas From early dinosaurs with as many as nine wrist bones, modern birds evolved to develop only four ossifications. Their identity is uncertain, with different labels used in palaeontology and developmental biology. We examined embryos of several species and studied chicken embryos in detail through a new technique allowing whole-mount immunofluorescence of the embryonic cartilaginous skeleton. Beyond previous controversy,…

  • Social Network Analysis Shows Direct Evidence for Social Transmission of Tool Use in Wild Chimpanzees

    Catherine Hobaiter et al.
    30 Sep 2014 | 2:00 pm
    by Catherine Hobaiter, Timothée Poisot, Klaus Zuberbühler, William Hoppitt, Thibaud Gruber Social network analysis methods have made it possible to test whether novel behaviors in animals spread through individual or social learning. To date, however, social network analysis of wild populations has been limited to static models that cannot precisely reflect the dynamics of learning, for instance, the impact of multiple observations across time. Here, we present a novel dynamic version of network analysis that is capable of capturing temporal aspects of acquisition—that is, how successive…

    by N. Lance Hepler, Konrad Scheffler, Steven Weaver, Ben Murrell, Douglas D. Richman, Dennis R. Burton, Pascal Poignard, Davey M. Smith, Sergei L. Kosakovsky Pond Since its identification in 1983, HIV-1 has been the focus of a research effort unprecedented in scope and difficulty, whose ultimate goals — a cure and a vaccine – remain elusive. One of the fundamental challenges in accomplishing these goals is the tremendous genetic variability of the virus, with some genes differing at as many as 40% of nucleotide positions among circulating strains. Because of this, the genetic bases of…
  • Clique of Functional Hubs Orchestrates Population Bursts in Developmentally Regulated Neural Networks

    Stefano Luccioli et al.
    25 Sep 2014 | 2:00 pm
    by Stefano Luccioli, Eshel Ben-Jacob, Ari Barzilai, Paolo Bonifazi, Alessandro Torcini It has recently been discovered that single neuron stimulation can impact network dynamics in immature and adult neuronal circuits. Here we report a novel mechanism which can explain in neuronal circuits, at an early stage of development, the peculiar role played by a few specific neurons in promoting/arresting the population activity. For this purpose, we consider a standard neuronal network model, with short-term synaptic plasticity, whose population activity is characterized by bursting behavior. The…
  • Multi-state Modeling of Biomolecules

    Melanie I. Stefan et al.
    25 Sep 2014 | 2:00 pm
    by Melanie I. Stefan, Thomas M. Bartol, Terrence J. Sejnowski, Mary B. Kennedy Multi-state modeling of biomolecules refers to a series of techniques used to represent and compute the behavior of biological molecules or complexes that can adopt a large number of possible functional states. Biological signaling systems often rely on complexes of biological macromolecules that can undergo several functionally significant modifications that are mutually compatible. Thus, they can exist in a very large number of functionally different states. Modeling such multi-state systems poses two problems:…
  • Identifying Cell Types from Spatially Referenced Single-Cell Expression Datasets

    by Jean-Baptiste Pettit, Raju Tomer, Kaia Achim, Sylvia Richardson, Lamiae Azizi, John Marioni Complex tissues, such as the brain, are composed of multiple different cell types, each of which have distinct and important roles, for example in neural function. Moreover, it has recently been appreciated that the cells that make up these sub-cell types themselves harbour significant cell-to-cell heterogeneity, in particular at the level of gene expression. The ability to study this heterogeneity has been revolutionised by advances in experimental technology, such as Wholemount in Situ…

    25 Sep 2014 | 2:00 pm
    by Sveta Chakrabarti, Mickaël Poidevin, Bruno Lemaitre The p38 mitogen-activated protein (MAP) kinase signaling cassette has been implicated in stress and immunity in evolutionarily diverse species. In response to a wide variety of physical, chemical and biological stresses p38 kinases phosphorylate various substrates, transcription factors of the ATF family and other protein kinases, regulating cellular adaptation to stress. The Drosophila genome encodes three p38 kinases named p38a, p38b and p38c. In this study, we have analyzed the role of p38c in the Drosophila intestine. The p38c gene…

Secondly, by “unsubscribing” you’re effectively telling the spammer that you actually opened their email…and so may be susceptible to more targeted spam later. Thirdly, if your unsubscribe goes back via email you’re sending all sorts of meta information about…

  • Using intelligence to unlock the market for electric vehicles

    1 Oct 2014 | 6:25 am
    Our fuel-based economy must be radically overhauled if Europe is to achieve its ambitious emission reduction targets. One important piece of this jigsaw could be the increased commercialisation of electric cars, which use carbon-free energy sources and emit no CO2 or other pollutants. As an added bonus, electric vehicles also create less noise and vibration.

  • Rare Evolutionary Twist Morphed Dino Arms into Bird Wings

    1 Oct 2014 | 5:21 am
    When dinosaurs evolved into birds, they had to adapt their arms into wings in order to take flight — a process that altered their skeletal structure. The pisiform, a crumb of bone that helps keeps birds' wings rigid on the upstroke, had vanished in the birdlike dinosaurs that were modern birds' closest ancestors, the researchers report today (Sept. 30) in the journal PLOS Biology. "It is rare," study researcher Alexander Vargas, who leads the ontology and phylogeny lab at the University of Chile in Santiago, told Live Science. Of the few accepted cases of such a…
  • Higgs Music: What the World’s Largest Atom Smasher Sounds Like

    1 Oct 2014 | 5:18 am
    The discovery of the Higgs boson, the particle thought to explain how other particles get their mass, was music to scientists' ears. Scientists took data from the ALICE, ATLAS CMS and LHCb detectors in the Large Hadron Collider (LHC), at CERN laboratory near Geneva, Switzerland, between 2011 and 2013, and turned it into a musical score that reveals what the Higgs boson would sound like. Composer and physicist Domenico Vicinanza created the music for CERN's 60th anniversary, and some of the lab's musically minded scientists performed the piece in the four experimental caverns that house the…

    A patient in Texas is the first person to be diagnosed with Ebola in the United States, according to the Centers for Disease Control and Prevention. The patient had previously traveled to West Africa, a region that is currently experiencing the worst outbreak of Ebola in history. The man flew out of Liberia on Sept. 19 and arrived in the United States on Sept. 20. He did not have symptoms during his flight or when he landed, but began showing symptoms around Sept. 24, Dr. Tom Frieden, director of the CDC, said at a news conference today.

  • The 9 Online Calculators You Need to Know About

    Olwen Reina

  • Protocols: Where Do You Get Yours?

    Catriona Paul
    29 Sep 2014 | 12:00 am
    Trying a new protocol is always a little daunting, especially if no one else in your lab is doing it. So it’s always good to find a tried and tested protocol from a reputable source before getting your hands dirty. Or at least one that can start you off in the right direction. It is not my intention here to provide an all-encompassing list of the places to find the best protocols, but to start a resource from my own experience that you will all hopefully contribute to, and that will grow over time. Books…..? Do they still exist? The internet is probably the most-used resource when looking…
  • Analyzing Apoptosis – A Review of Analytical Techniques

    Laura-Nadine Schuhmacher
    24 Sep 2014 | 12:30 am
    Now that we’ve learned about the role of apoptosis in good health and disease, it will be useful to know how we can detect apoptosis in cells or organisms. A variety of apoptosis detection kits are commercially available, and here is a roundup of how they work: TUNEL and DNA damage assays The TUNEL assay is probably the most widely used method to visualize apoptosis in fixed cells. Published by Gavrieli et al. 1992, it relies on the visualization of DNA degradation, more specifically, the identification of nicked DNA by terminal deoxynucleotidyl transferase. This enzyme recognizes broken…
  • Looking good! A Guide to Adjusting and Maintaining Microscope Eyepieces

    Martin Wilson
    23 Sep 2014 | 2:34 pm
    The magnification and viewing of samples using a microscope relies on both the objectives and the eyepieces working harmoniously together. If you buy a ready-to-use microscope, then the objectives and the eyepieces which are fitted as standard will be designed to complement each other. On the other hand, if you are designing and building a research microscope, then the choice of objectives will determine which eyepieces are suitable for the optics and lenses contained within the objectives. Eyepieces are also known as ‘ocular lenses’ or ‘oculars’. Eyepieces simply magnify your…

What is an expression system anyway? There was a time not so long ago when genetic engineering was not just unheard of, but also undreamt of. But the pre-historic biochemists still managed to purify significant quantities of several proteins by sifting through tons of raw tissue in slaughterhouses.

    A new class of compounds, given orally, protects brain cells from the damage caused by blast-induced traumatic brain injury and preserves normal brain functions, even when the compound is given 24 to 36 hours after the injury occurs. The researchers hope that this family of compounds might be developed into a new class of neuroprotective drugs for TBI and other currently untreatable forms of neurodegeneration, including Alzheimer's disease and ALS.

The findings show that some parts of the brain behave similarly whether we are asleep or awake and pave the way for further studies on the processing capacity of our sleeping brains, the researchers say.

    In states like Colorado where marijuana is legal for adults, some people may think that gives them a license to be high all the time. But they would be wrong. Just because the law allows adults the option to use marijuana, it does not mean that it is always legal for them to be high. To break it down, in Colorado: Marijuana Is Legal for Adults And Driving Is Legal for People With a License But Marijuana + Driving is Not Legal And this is for a good reason.

People who write about the health benefits of marijuana sometimes think it’s ironic that a plant containing compounds that could treat disease (like THC or CBD) is banned by the government for being unsafe. But in fact many effective, FDA-approved medicines are closely related to illegal, harmful drugs and are sometimes even made from the same sources. That’s because there’s a fine (and sometimes fuzzy)…

    In June, we shared the Centers for Disease Control and Prevention data that tens of thousands died from drug use in 2010.  In 2011, the number of drug overdose deaths continued to rise.  To compare the data from 2010 to 2011, view the original post.  You’ll see that in just one year there has been an increase of over 3,000 deaths—nearly 8%—between 2010 and 2011. More than half of those overdose deaths (55%) are related to prescription drug abuse, and of those, 74% (16,917) were due to opioids (prescription pain medications).

What people usually mean by “medical marijuana” is use of an unprocessed (raw) plant to treat illness—or herbal medicine, in other words. Unprocessed means the leaves, stems, or seeds are just taken off the plant and used. Before the 20th century, that’s mostly what medicine was. But science has made a lot of progress in the last several decades, and generally it…

The reddish disc of the Moon is seen on the right of the image, while the Milky Way arches across the heavens in all its beauty. Another faint glow of light is also visible, surrounding the brilliant planet Venus in the bottom left corner of the picture. This phenomenon, known as zodiacal light, is produced by sunlight reflecting off dust in the plane of the planets. It is so faint…
  • Cassini Spacecraft Tracks Mystery Object in a Titan Sea
    30 Sep 2014 | 3:00 am
    NASA's Cassini spacecraft is monitoring the evolution of a mysterious feature in a large hydrocarbon sea on Saturn's moon Titan. The feature covers an area of about 100 square miles (260 square kilometers) in Ligeia Mare, one of the largest seas on Titan. It has now been observed twice by Cassini's radar experiment, but its appearance changed between the two apparitions. The mysterious feature, which appears bright in radar images against the dark background of the liquid sea, was first spotted during Cassini's July 2013 Titan flyby. Previous observations showed no sign of bright features in…
  • Extreme Alien Planet Found -"One of the Most Massive Known Exoplanets"
    30 Sep 2014 | 2:00 am
    A planet may be causing the star it orbits to act much older than it actually is, according to new data from NASA’s Chandra X-ray Observatory. This discovery shows how a massive planet can affect the behavior of its parent star. The star, WASP-18, and its planet, WASP-18b, are located about 330 light-years from Earth. WASP-18b has a mass about 10 times that of Jupiter and completes one orbit around its star in less than 23 hours, placing WASP-18b in the “hot Jupiter” category of exoplanets, or planets outside our solar system. WASP-18b is the first known example of an orbiting planet…
  • Resurrecting 4-Billion-Year-Old Proteins to Decode Earth's Early Epochs --"Will Aid Our Search for Life in the Universe"
    29 Sep 2014 | 9:11 am
    Thanks to advances in a niche field called paleobiochemistry, researchers in the last decade have started to “resurrect” ancient proteins. Studying these proteins’ properties is offering us glimpses of what life was like in bygone epochs. “Although the majority of resurrection studies currently focus on resurrecting one or two protein families at a time,” says Eric Gaucher, a pioneering paleobiochemist and a professor biology at Georgia Tech. “we anticipate that we will be able to resurrect a complete ancestral genome in the near future and jump-start this genome using modern life…

  • Food Contaminants

    13 Sep 2014 | 5:20 pm
    There is a greater reason than aesthetics to insist on clean hands at all times. Salmonella, the most common form of food poisoning and one that can kill the elderly and infirm, is often transmitted by urine. Diarrhea and dysentery often come from feces.However, the good news is that the least likely source of food poisoning is a dirty person. The classic case of “Typhoid Mary,” an itinerant dishwasher who spread typhoid wherever she worked, is long gone.Far more dangerous are bad food storage disciplines. Raw meat and cooked meat must not collide. A butcher or chef who has handled raw…

    In this section we will look at the main types of alternative fuels. We start with Biofuels as this constitutes probably the most popular AF currently in use.BiofuelsMuch recent attention has been focused on biofuels. This is highlighted economically by the fact that worldwide investment in biofuels rose from US$5bn in 1995 to US$38bn in 2005, owing to substantial investments by companies such as BP, Shell and Ford, and by Richard Branson (Grunwald, 2008).Biofuels are essentially fuels produced from renewable plant material and oils.

  • New Trend Alert: Using Video to Introduce Data

    Emily Poulin
    3 Sep 2014 | 12:46 pm
    Here at BenchFly, we’re always looking for new ways to use video to improve scientific research. During a recent conference in Europe, the value of using video to simply introduce a research topic hit home with me. An exciting part of being a researcher of any level is the opportunity to travel to research conferences held all over the country and the world. However, the tricky part about a conference is that while the audience is typically knowledgeable about the general topic, there are so many contexts in which the specific topic can be covered. Do you work in animals? Cell culture? The…

    “Set timer for ten minutes.” Instead of the kitchen timers the rest of us use, the post-doc sitting behind me regularly uses Siri to time his experiments. As it turns out, it’s actually easier to tell a computer to set a timer for you than to do it yourself, and Siri is quickly becoming our lab’s newest research assistant. With a new iPhone model out each year, it’s not hard to believe that we’ll soon have everything we need on the little 2¼” x 4¾” device we can no longer go anywhere without.

  • Disappearing Lakes: Most Of Aral Sea Is Gone

    Daniel Kelly

    Once the world’s fourth largest lake, the Aral Sea has shrunk considerably in the last 50 years. Summer 2014 marked further decline, according to a release from NASA, as the eastern basin of the diminished water body has gone dry for the first time in modern history. Not since medieval times has the Aral Sea been this dry, when water from one of its tributaries was diverted to the Caspian Sea. But the cause of that dry period isn’t so different from those draining the Aral Sea today. The Aral Sea loses its eastern lobe, August 19, 2014. (Credit: NASA Earth Observatory) Troubles began in…

  • Research Summary: Distribution, Seasonality And Putative Origin Of Non-Native Red Alga Bangia Atropurpurea In The Laurentian Great Lakes

    Daniel Kelly
    24 Sep 2014 | 6:58 am
    The red alga, Bangia atropurpurea, was initially described by Roth in 1805 from the Weser River in Germany and since then has been reported from rivers in Europe and Asia. In 1964, the first observation of this species in North American freshwaters was in Buffalo Harbor, Lake Erie (Lin & Blum, 1977) and from the mid-to-late 1970s it spread throughout the lower Laurentian Great Lakes. Initially, it was hypothesized to be conspecific with the marine species, Bangia fuscopurpurea, especially since the latter can acclimate to freshwater (Geesink, 1973); thus, it was proposed that this species…

It is a tricky balancing act. Cut too many corners and release a product too soon, and you risk a withering backlash. Release a product too late and your competitors become established on the high ground and you are left playing catch-up. Finding the sweet-spot in the middle, now that is the trick. One…

    Things can and do go wrong when some announcements are mad ahead of time. Flickr/Narshada, CC BY-NDUNDERSTANDING RESEARCH: What do we actually mean by research and how does it help inform our understanding of things? Today a cautionary tale of why you should be careful of some new announcements made in the name of science. It was dubbed a “spectacular” discovery – even “Nobel prize-worthy”. But the March announcement via a press conference that researchers at the BICEP2 facility in Antarctica had detected the imprint of relic gravitational waves from a period of super-fast…

  • Spiders on drugs

    28 Sep 2014 | 9:25 am
    Back in the day, when I was freelancing regularly for New Scientist, the magazine covered the story of the errant webs created by spiders that had been exposed to (THC) from marijuana, LSD, speed and various other drugs including caffeine and alcohol . This was an issue in 1995, if I remember rightly. There was a follow up a “humourous” video many years later, which you can watch here: As you can see the spiders don’t do their best work when they’re stoned on various psychoactive drugs and the social outcomes are not optimal it has to be said. The original New…

    My latest news story for Chemistry World is on the topic of stationary energy storage and a rather unique concept – liquid metal batteries. Researchers at MIT have developed such a device, which could allow electricity generated by intermittent, but renewable sources, such as wind, solar and wave power. Such a battery could lower the overall costs of energy storage while also having the advantages of small physical footprint and mechanical simplicity. Stanford University materials scientist Robert Huggins was very positive of the development: “There is currently a large amount of…

    UPDATE: To avoid confusion: eating lots of tomatoes will not stop you getting prostate cancer if other risk factors are in place! At least 20 years ago I wrote a news story in my rookie days about how the natural red pigment in tomatoes, the antioxidant lycopene, could somehow protect men against prostate cancer. Nothing was ever proven and the latest news which hit the tabloids in the last couple of weeks doesn’t add much, at least if you read between the lines. NHS Choices, as ever, has a good summary: “This large study has shown an association between the consumption of more…

Farmers’ markets practically glow with wholesome virtue: Shop here, they promise, and you can help build a sustainable, healthy food system!

  • Dry roasting a trigger for peanut allergy

    1 Oct 2014 | 12:00 am
    There is a striking difference between the prevalence of peanut allergies in the Western world and the East and it could be down to the way the nuts are prepared. Dry roasted peanuts are more likely to trigger an allergy than raw peanuts say researchers from the University of Oxford. They believe specific chemical changes caused by the high temperature of the dry roasting process are recognised by the body’s immune system, priming an allergic immune response next time it encounters peanuts. The team purified proteins from dry roasted and raw peanuts and introduced them to mice in three…
  • Superheavy element pairing probes Einstein’s relativity

    30 Sep 2014 | 12:00 am
    Chemists probing the predictive power of trends in the Periodic Table have successfully established a chemical bond between a superheavy element and a carbon atom. The pairing, between seaborgium and a carbon atom, offers the chance for more detailed investigation into the chemical behaviour of elements at the end of the table where the effects of Einstein’s relativity on chemical properties are most pronounced. Many positively charges protons in atomic nuclei accelerate electrons to very high velocities – about 80% the speed of light. Einstein’s theory of relativity states that…

    By jamming their ‘paper shredder’, scientists might be able to drown deadly bacteria in their own paperwork. Researchers from the University of Leeds have identified how this paper shredder works to allow E. coli to keep on top of its day job. “If we block the ‘shredder’ using genetics in the lab, the bacteria drown in a flood of messages,” said Dr Kenneth McDowall, Associate Professor in Molecular Biology. “The challenge now if to block it with drugs so that bacterial infections in humans can be killed.

  • Leviathan: The Energy Giant that Sleeps under the Mediterranean

    28 Sep 2014 | 9:32 am
    The Leviathan Natural Gas Field The Leviathan is a large natural gas field located in the Eastern Mediterranean Sea.  Together with the nearby Tamar gas field, the Leviathan has been seen as an opportunity for Israel to become a major energy power in the Middle East.  This is the Leviathan - a giant gas field with the titanic potential to change Israel's foreign relations towards a closer collaboration with Turkey and Egypt.  Good news in an uncertain energy security climate... Off the coast of Israel, about 47 kilometres 29 miles south-west of the Tamar gas field, the Leviathan gas…

  • You Don’t Need 8 Glasses Of Water A Day

    Emily Oster
    30 Sep 2014 | 5:14 am
    Some central tenets of good health: more vegetables, less soda, lots of exercise. And let’s not forget water: at least eight glasses a day. Much ink is spilled over the first three of these recommendations, but the last sometimes seems to be taken for granted by all the people lugging around Nalgene bottles. Is drinking so much water necessary? Is reaching eight glasses per day crucial to good health?The short answer — at least to the specific question of eight glasses versus, say, seven or nine — is no, there is nothing special about eight. This threshold appears to be a…
  • The Natural Gas Boom Could Accelerate Climate Change

    Brooks Miner
    26 Sep 2014 | 7:51 am
    Natural gas production in the United States is booming: Since 2005, it has increased by 35 percent,1 and with each passing year the country burns more gas, and less coal and oil. Natural gas emits far less carbon dioxide than coal or oil, and the gas boom has driven a decline in U.S. carbon dioxide emissions over the past decade. The boom stems largely from the shale gas revolution, in which hydraulic fracturing and horizontal drilling (“fracking”) allows recovery of natural gas and petroleum trapped in underground shale formations.Policymakers have hailed this revolution as beneficial in…

    8 Sep 2014 | 3:12 am
    Based on a perusal of the vitamin section of most drug stores, you’d think Americans need a lot of vitamins. And almost 50 percent of adult Americans reported taking some dietary supplement, according to the most recently published data in the 2009-2010 National Health and Nutrition Examination Survey (NHANES). People take specific vitamin supplements, of course — B, C, D, E and so on — and if taking one vitamin at a time is too much, one-a-day multivitamins abound, designed for each specific life circumstance.

    Over the years, overfishing, pollution and habitat destruction have been slowly eating away at our environment. In the UK alone, almost two thirds of species have declined in the past 50 years, yet all we can ask ourselves is why have we let this build of carbon dioxide so rapidly overtake the lives of hundreds of animals. Small rehabilitation projects are taking place throughout the UK, such as endangered small white crayfish being collected and re-released into the River Glaven, Norfolk by the Environmental agency[1] and the attempted breeding of panda’s in Edinburgh Zoo by the RZSS…

    Good  vitamin D can help combat pancreatic cancer. U.S. researchers have found an amped-up version of vitamin D can make pancreatic cancer tumours more vulnerable to chemotherapy. The study from the Salk Institute in California found a drug the researchers developed that makes vitamin D more stable, resilient and effective increased the lifespan of mice by up to 50% when combined with chemotherapy compared to chemotherapy treatments alone. The addition of the synthetic vitamin D analog calcipotriol to gemcitabine chemotherapy enhanced survival in the pancreatic cancer mouse model by 57%,…

    A manned trip to Mars is still many years away, but would-be travelers have been training for their maiden interplanetary spaceflight for a while now. One such project is Mars-500. On a summer day in 2010, six people went into a 550 cubic-meter chamber of four hermetically sealed, interconnected tubes, inside a research facility, outside Moscow. There, they were to spend the next 520 days—the time it takes to go to Mars, touchdown, and return—locked in that cramped space, about the size of a spacecraft cabin, cut off from the outside. They were to breathe recycled air, eat rehydratable…

    If you’re a keen gamer maybe it’s difficult to put the controller down and turn off the Xbox or Playstation, and detach yourself from the virtual world you were experiencing. It’s possible you’ll continue thinking about the game well into the rest of the day or night, planning and strategising. This is pretty normal behaviour for a devout gamer (who doesn’t think about what they have done wrong and how to plan their next move in life? the only difference here is that it’s virtual) but where does the line get drawn for when a gamers’ behaviour gets a little little too warped?

    Anyone familiar with the works of Richard Serra, the American Minimalist, knows that he’s singularly devoted to a single color, whether graphite, ink, charcoal, or PaintStick—black. His steel-plate pieces or circles are all utterly black. Space is black. Acoustic speakers are black. Tar is black. Ebony is black. But all that black pales, literally, in comparison to a material created by Surrey NanoSystems, a British nanotechnology company, based in New Haven, England. The substance called Vantablack is so intensely black that when you gaze into anything coated with it, you don’t see it.

    30 Sep 2014 | 10:35 am
    By Anupum Pant Here’s an image of a contraption. It is basically a long stick hinged at one end and is free to move about the other. At the end of it rests a ball. Near the ball there’s also a cup fastened to the stick. The big stick is lifted up high and is temporarily supported by a small stick. Now, what do you think would happen when the temporary support is removed? Normally, it would be very intuitive to think that the cup and the ball would fall at the same speed. In other words, nothing fascinating would happen. Both would fall and the ball would roll away…no?

Now, if another pendulum is attached to the bottom of this first pendulum, preferably using a rod (not a string), and is then given a good amount of initial energy, things move from a simple single pendulum to a very complicated two pendulum system. The system turns so chaotic that it is impossible to make two of such exactly same systems, forget keeping them synchronised. Even if…

Unlike the most crystalline metals, BMGs are made by cooling certain liquid metals very quickly to lock the disordered glassy structure in place. They aren’t crystalline like your everyday metals and instead have a structure like that of glasses – disordered. Some of these BMGs have amazing properties.

His first theory, in simple words, tried to explain the way our performance at some tasks increases in the presence of others, while the performance at some other tasks decreases. According to him, the presence of other individuals around you serves as a source of “arousal” and affects performance (in good ways some times and bad ways the other times). When this happens, he said, humans tend to do well at tasks which they are…

    An animal's ability to survive the fallout from a nuclear explosion is usually dependent on its ability to withstand radiation, otherwise know as radioresistance. Radioresistant life forms or ionizing-radiation-resistant organisms (IRRO) are a group of organisms that require large doses of radiation, 1000 gray (Gy), to achieve a 90% reduction in their survival rate. To put it in perspective, a human would need anywhere between 4-10 (Gy) to achieve the same result and a dog could withstand even less, about 3.5 (Gy). Gray, with the symbol of (Gy), is a unit of measurement used to describe the…
