  • Ebola outbreak likely started at a funeral

    Keith Brannon-Tulane
    2 Sep 2014 | 7:12 am
    The current Ebola outbreak sweeping through West Africa likely began at the funeral of a healer in Sierra Leone. “The funeral was for an herbalist or traditional medicine practitioner in Koindu, a town in Sierra Leone,” says Robert Garry, professor of microbiology and immunology at Tulane University. “The herbalist had treated several patients from neighboring Guinea, one or more of whom were apparently infected with Ebola virus.” Scientists were able to sequence 99 Ebola virus genomes using blood samples from 78 patients, painting a record “real-time”…

    Seven out of ten Americans say the recent recession’s impact will be permanent—that’s up from five out of ten in 2009 when the slump officially ended. Other the key findings of the John J. Heldrich Center for Workforce Development’s latest Work Trends report, include: Despite sustained job growth and lower levels of employment, most Americans do not think the economy has improved in the last year or that it will in the next. Just one in six Americans believes that job opportunities for the next generation will be better than for theirs; five years ago, four in ten held…
  • This is probably how fish evolved to walk on land

    Cynthia Lee-McGill
    29 Aug 2014 | 1:45 pm
    Researchers are using a living fish, called Polypterus, to help show what might have happened when fish first tried to walk out of the water. Polypterus is an African fish that can breathe air, “walk” on land, and looks much like those ancient fishes that evolved into tetrapods. About 400 million years ago, a group of fish began exploring land and evolved into tetrapods—today’s amphibians, reptiles, birds, and mammals. But just how these ancient fish used their fishy bodies and fins in a terrestrial environment and what evolutionary processes were at play remain…
  • Toxic metals in E-cigarette smoke raise red flags

    29 Aug 2014 | 8:18 am
    While smoke from electronic cigarettes may not have cancer-causing agents, it does have higher levels of some toxic metals compared to traditional cigarettes. Electronic cigarette smoke contains the toxic element chromium, which is absent from traditional cigarettes, as well as nickel at levels four times higher than normal cigarettes. Several other toxic metals such as lead and zinc were also found in second-hand e-cigarette smoke—though in concentrations lower than for normal cigarettes. “Our results demonstrate that overall electronic cigarettes seem to be less harmful than regular…

  • Corals: Not So Passive, They Are Nature's Tiny Engineers

    News Staff
    2 Sep 2014 | 6:02 am
    Corals, whose calcium-carbonate skeletons form the foundation of coral reefs, are passive organisms that rely entirely on ocean currents to deliver dissolved substances, such as nutrients and oxygen. Or so it seemed. Scientists at MIT and the Weizmann Institute of Science (WIS) in Israel have found that they are far from passive, engineering their environment to sweep water into turbulent patterns that greatly enhance their ability to exchange nutrients and dissolved gases with their environment. read more

A world that is as creative and complex as it is dangerous and disturbing.

    The news was full of the discovery that taking some aspirin every day for ten years could somehow reduce your risk of getting cancer, particularly cancers of the gastrointestinal tract. The stomach bleeding side-effect (for some) and other as yet unknown side-effects aside, I was skeptical from the start, it just looked like a review of reviews where they looked at the idea that taking aspirin for years and years might somehow correlate with not getting cancer. To me, this is like the inverse of so many other studies that purportedly “prove” that such and such an exposure to food,…

    In the yawns of wolves, scientists have found a hint of emotional depths once thought restricted to humans and our closest ancestors. Contagious yawning — the tendency to involuntarily follow suit when seeing another person yawn — is thought to be linked to empathy, drawing on some of the same cognitive mechanisms that underlie our ability to share the feelings of others. According to a new study, wolves yawn contagiously, too.

    Neurology journal Neurocase has an interesting study of a women who started compulsively writing poetry after having brief epileptic amnesia treated with the anti-seizure drug lamotrigine. A 76-year-old woman reported having a poor memory and short periods of disorientation and was eventually diagnosed with transient epileptic amnesia – brief recurrent seizures that lead to short periods where affected people can’t lay down new memories. Several months after starting lamotrigine [a common and widely used anti-seizure drug], the patient suddenly began to write original verse.

Language's evolutionary analysis is complicated because it has no equivalent in any nonhuman species. There is also no consensus regarding the essential nature of the language “phenotype.” According to the “Strong Minimalist Thesis,” the key distinguishing feature of language (and what evolutionary theory must explain) is hierarchical syntactic structure.

Wymeersch, Yali Huang, Jens Kleinjung, Valerie Wilson, James Briscoe Cells of the spinal cord and somites arise from shared, dual-fated precursors, located towards the posterior of the elongating embryo. Here we show that these neuromesodermal progenitors (NMPs) can readily be generated in vitro from mouse and human pluripotent stem cells by activating Wnt and Fgf signalling, timed to emulate in vivo development. Similar to NMPs in vivo, these cells co-express the neural factor Sox2 and the mesodermal factor Brachyury and differentiate into neural…

P. Holstege, Balázs Papp, Csaba Pál Adaptive evolution is generally assumed to progress through the accumulation of beneficial mutations. However, as deleterious mutations are common in natural populations, they generate a strong selection pressure to mitigate their detrimental effects through compensatory genetic changes. This process can potentially influence directions of adaptive…

  • Possible Role of Interleukin-1β in Type 2 Diabetes Onset and Implications for Anti-inflammatory Therapy Strategies

    Gang Zhao et al.
    28 Aug 2014 | 2:00 pm
    by Gang Zhao, Gitanjali Dharmadhikari, Kathrin Maedler, Michael Meyer-Hermann Increasing evidence of a role of chronic inflammation in type 2 diabetes progression has led to the development of therapies targeting the immune system. We develop a model of interleukin-1β dynamics in order to explain principles of disease onset. The parameters in the model are derived from in vitro experiments and patient data. In the framework of this model, an IL-1β switch is sufficient and necessary to account for type 2 diabetes onset. The model suggests that treatments targeting glucose bear the potential…
  • Dynamic Modelling of Pathways to Cellular Senescence Reveals Strategies for Targeted Interventions

    Piero Dalle Pezze et al.
    28 Aug 2014 | 2:00 pm
    by Piero Dalle Pezze, Glyn Nelson, Elsje G. Otten, Viktor I. Korolchuk, Thomas B. L. Kirkwood, Thomas von Zglinicki, Daryl P. Shanley Cellular senescence, a state of irreversible cell cycle arrest, is thought to help protect an organism from cancer, yet also contributes to ageing. The changes which occur in senescence are controlled by networks of multiple signalling and feedback pathways at the cellular level, and the interplay between these is difficult to predict and understand. To unravel the intrinsic challenges of understanding such a highly networked system, we have taken a systems…
  • Identification of Allelic Imbalance with a Statistical Model for Subtle Genomic Mosaicism

    Rui Xia et al.
    28 Aug 2014 | 2:00 pm
    by Rui Xia, Selina Vattathil, Paul Scheet Genetic heterogeneity in a mixed sample of tumor and normal DNA can confound characterization of the tumor genome. Numerous computational methods have been proposed to detect aberrations in DNA samples from tumor and normal tissue mixtures. Most of these require tumor purities to be at least 10–15%. Here, we present a statistical model to capture information, contained in the individual's germline haplotypes, about expected patterns in the B allele frequencies from SNP microarrays while fully modeling their magnitude, the first such model for SNP…
  • Unbiased Functional Clustering of Gene Variants with a Phenotypic-Linkage Network

    Frantisek Honti et al.
    28 Aug 2014 | 2:00 pm
    by Frantisek Honti, Stephen Meader, Caleb Webber Groupwise functional analysis of gene variants is becoming standard in next-generation sequencing studies. As the function of many genes is unknown and their classification to pathways is scant, functional associations between genes are often inferred from large-scale omics data. Such data types—including protein–protein interactions and gene co-expression networks—are used to examine the interrelations of the implicated genes. Statistical significance is assessed by comparing the interconnectedness of the mutated genes with that of…

  • Integration of UPRER and Oxidative Stress Signaling in the Control of Intestinal Stem Cell Proliferation

    Lifen Wang et al.
    28 Aug 2014 | 2:00 pm
    by Lifen Wang, Xiankun Zeng, Hyung Don Ryoo, Heinrich Jasper The Unfolded Protein Response of the endoplasmic reticulum (UPRER) controls proteostasis by adjusting the protein folding capacity of the ER to environmental and cell-intrinsic conditions. In metazoans, loss of proteostasis results in degenerative and proliferative diseases and cancers. The cellular and molecular mechanisms causing these phenotypes remain poorly understood. Here we show that the UPRER is a critical regulator of intestinal stem cell (ISC) quiescence in Drosophila melanogaster. We find that ISCs require activation of…
  • The Groucho Co-repressor Is Primarily Recruited to Local Target Sites in Active Chromatin to Attenuate Transcription

    Aamna Kaul et al.
    28 Aug 2014 | 2:00 pm
    by Aamna Kaul, Eugene Schuster, Barbara H. Jennings Gene expression is regulated by the complex interaction between transcriptional activators and repressors, which function in part by recruiting histone-modifying enzymes to control accessibility of DNA to RNA polymerase. The evolutionarily conserved family of Groucho/Transducin-Like Enhancer of split (Gro/TLE) proteins act as co-repressors for numerous transcription factors. Gro/TLE proteins act in several key pathways during development (including Notch and Wnt signaling), and are implicated in the pathogenesis of several human cancers.
  • Multiple Regulation of Rad51-Mediated Homologous Recombination by Fission Yeast Fbh1

    Yasuhiro Tsutsui et al.
    28 Aug 2014 | 2:00 pm
    by Yasuhiro Tsutsui, Yumiko Kurokawa, Kentaro Ito, Md. Shahjahan P. Siddique, Yumiko Kawano, Fumiaki Yamao, Hiroshi Iwasaki Fbh1, an F-box helicase related to bacterial UvrD, has been proposed to modulate homologous recombination in fission yeast. We provide several lines of evidence for such modulation. Fbh1, but not the related helicases Srs2 and Rqh1, suppressed the formation of crossover recombinants from single HO-induced DNA double-strand breaks. Purified Fbh1 in complex with Skp1 (Fbh1-Skp1 complex) inhibited Rad51-driven DNA strand exchange by disrupting Rad51 nucleoprotein filaments…

    by Cristina Tocchini, Jeremy J. Keusch, Sarah B. Miller, Susanne Finger, Heinz Gut, Michael B. Stadler, Rafal Ciosk The mechanisms controlling cell fate determination and reprogramming are fundamental for development. A profound reprogramming, allowing the production of pluripotent cells in early embryos, takes place during the oocyte-to-embryo transition. To understand how the oocyte reprogramming potential is controlled, we sought Caenorhabditis elegans mutants in which embryonic transcription is initiated precociously in germ cells. This screen identified LIN-41, a TRIM-NHL protein and a…

    James A. Tsatsaronis et al.
    28 Aug 2014 | 2:00 pm
    by James A. Tsatsaronis, Mark J. Walker, Martina L. Sanderson-Smith Infections caused by group A Streptococcus (GAS) are characterized by robust inflammatory responses and can rapidly lead to life-threatening disease manifestations. However, host mechanisms that respond to GAS, which may influence disease pathology, are understudied. Recent works indicate that GAS infection is recognized by multiple extracellular and intracellular receptors and activates cell signalling via discrete pathways. Host leukocyte receptor binding to GAS-derived products mediates release of inflammatory mediators…
  • TLR2 Signaling Decreases Transmission of Streptococcus pneumoniae by Limiting Bacterial Shedding in an Infant Mouse Influenza A Co-infection Model

    by Aimee L. Richard, Steven J. Siegel, Jan Erikson, Jeffrey N. Weiser While the importance of transmission of pathogens is widely accepted, there is currently little mechanistic understanding of this process. Nasal carriage of Streptococcus pneumoniae (the pneumococcus) is common in humans, especially in early childhood, and is a prerequisite for the development of disease and transmission among hosts. In this study, we adapted an infant mouse model to elucidate host determinants of transmission of S. pneumoniae from inoculated index mice to uninfected contact mice. In the context of…
  • Human Cytomegalovirus pUL79 Is an Elongation Factor of RNA Polymerase II for Viral Gene Transcription

    Yi-Chieh Perng et al.
    28 Aug 2014 | 2:00 pm
    by Yi-Chieh Perng, Jessica A. Campbell, Deborah J. Lenschow, Dong Yu In this study, we have identified a unique mechanism in which human cytomegalovirus (HCMV) protein pUL79 acts as an elongation factor to direct cellular RNA polymerase II for viral transcription during late times of infection. We and others previously reported that pUL79 and its homologues are required for viral transcript accumulation after viral DNA synthesis. We hypothesized that pUL79 represented a unique mechanism to regulate viral transcription at late times during HCMV infection. To test this hypothesis, we analyzed…

    7 Aug 2014 | 6:23 pm
    Flying south for the winter? ENLARGE A fixture of temperate meadows and marshes, the unmistakable red-winged blackbird also jet sets to warmer winter weather, reaching as far as Guatemala. Unlike many passerines, the red-winged blackbird migrates during the day. Red-winged Blackbird photo from Shutterstock. In American slang, millions of “snowbirds” bail out of the North American winter and fly to a warmer climate. Now we learn that human snowbirds are simply emulating a pattern set by a large group of Western-Hemisphere birds. Hundreds of North American birds migrate south for…

  • The striatum acts as hub for multisensory integration

    2 Sep 2014 | 12:00 am
    A new study from Karolinska Institutet in Sweden provides insight on how the brain processes external input such as touch, vision or sound from different sources and sides of the body, in order to select and generate adequate movements. The findings, which are presented in the journal Neuron, show that the striatum acts as a sensory 'hub' integrating various types of sensory information, with specialized functional roles for the different neuron types.

    Image: Both the effects of marijuana and alcohol have on the human brain have been widely studied, but the same thing can’t be said about the combination of the two, which is rather odd considering a lot of people enjoy a drink or two while packing a bowl. Scott Lukas, a professor at Harvard Medical School, investigated what happens in the brain while cross-faded in 2011 and came to some surprising conclusions. First off, it’s important to note that marijuana (THC to be more specific) and alcohol are two psychoactive substances that are far from being similar to one…
  • Amazing fungus gnat larvae group together to form a ‘snake’ [VIDEO]

    Fungus gnats (Bradysia species) – also known as dark-winged fungus gnats, are small, mosquito-like insects often found in homes and offices, usually in the vicinity of houseplants. The larvae that hatch are legless, with white or transparent bodies and shiny black heads. From the first glimpse you’ll notice they’re not the prettiest sight, but what they lack in looks, they make up in cleverness. The fungus gnat larvae are incredibly vulnerable when alone; they’re puny, non-poisonous and practically at the mercy of predators – basically anything larger than them. To…

What remains of the star is a small and extremely dense remnant: a neutron star or a black hole. Neutron stars come in several flavours, depending on properties such as their ages, the strength of the magnetic field concealed beneath their surface, or the presence of other stars nearby. Some of the energetic processes taking place around neutron stars can be explored with X-ray telescopes, like ESA's XMM-Newton. This image depicts two very different neutron stars that were…

    It may sound like science fiction, but astronomers have worked out a scheme that will allow them to detect and measure particles ten times smaller than the width of a human hair, even at many light-years distance. They can do this by observing a blue tint in the light from far-off objects caused by the way in which small particles, no more than a micron in size (one-thousandth of a millimeter) scatter light. In a recent study conducted by Adrian Brown of the SETI Institute, the broad outlines of this process have been worked out. “The effect is related to a familiar phenomenon known as…

Isotope 56Co has a half-life of just 77 days, and does not exist in normal conditions. However, during a giant thermonuclear explosion of a supernova, this short-lived radioactive isotope is produced in large quantities. The reason was the rarity of explosions at such a distance – 11 million light-years is a large value on the galactic scale (the diameter of a galaxy is about 100,000 light-years, the distance between stars is a…

  • Avoid Pouring Chemicals–and Your Reputation–Down the Drain

    Dora Farkas
    30 Sep 2013 | 7:00 am
    Dear Dora, Everyone in my new lab pours all sorts of solvents down the drain and says it’s ok because they flush with a lot of water. I’m a first-year graduate student so maybe this is how all labs work, but it seems crazy. Is there a way for me to bring this issue up without being the annoying newbie? - anonymous, first year graduate student   Dear Anonymous Graduate Student, You are right to be concerned about others pouring solvents down the drain. Besides being an environmental hazard, your university can get fined thousands of dollars by the environmental agencies. Some…
  • The Science of Thriving: Empowering Your Life in the Lab

    16 Sep 2013 | 8:19 am
    Anyone who has worked in a lab for more than a month understands that with the great excitement of research also comes frustration. This is part of the process of working at the forefront of knowledge–some ideas are going to work and some aren’t. As scientists, our job is to make advances in our understanding of the world around us and that doesn’t always come easily. However, we understand (first hand!) the toll that failed experiments can have on our attitude, motivation, and general outlook on career prospects. But if “understanding our experiments” is a…

    28 Aug 2014 | 6:58 am
    Officials with the Minnesota Department of Natural Resources say the biomass of zebra mussels in Lake Mille Lacs dwarfs that of walleye, according to the Minneapolis Star Tribune. Around 2 million pounds of walleye exist in Mille Lacs, they say, offset by close to 2 billion pounds of zebra mussels. The figure is eye-opening, says Tom Jones, regional treaty coordinator at the DNR’s Aitkin, Minn. fisheries office. But there have been decreases to the invasive mussels’ numbers in recent years.

  • Research Summary: Mercury Biomagnification In Three Geothermally-Influenced Lakes Differing In Chemistry And Algal Biomass

    Daniel Kelly
    27 Aug 2014 | 6:01 am
    Mercury (Hg) biomagnifies in aquatic organisms, meaning that concentrations in tissues of biota increase as trophic position in food chains increases. Highest Hg concentrations are expected in top predators such as trout. The effects of environmental factors including biomass dilution in concert on biomagnification of Hg remain insufficiently known and warrant investigation. Various environmental variables have been shown to correlate positively (water temperature, organic matter in the sediment) or negatively (conductivity, pH, alkalinity, and concentrations of dissolved oxygen, Ca and SO4)…
  • Majority Of Lake Mendota’s Phosphorus Flows In During Just 29 Days Each Year

    Daniel Kelly

    Researchers at the University of Wisconsin – Madison have found that most of the phosphorus making it into Lake Mendota each year gets there over the course of just 29 days, according to The Capital Times. Their findings may help manage loads of phosphorus entering the lake in the future. Most of the 29 days occur in the spring or late winter, when sudden increases in precipitation are more common. Nearly three-quarters of Mendota’s yearly phosphorus budget is filled during those times. “We’re getting bigger storms, and high-load days are associated with bigger storms,” said…

    21 Aug 2014 | 8:18 am
    Water samples collected from Antarctica’s Lake Whillans in 2013 have been found to contain microbial life, according to the Los Angeles Times. Researchers involved with the project say the single-celled organisms manage to survive without ever seeing the light of the sun. Details of the discovery are published in the journal Nature and some have called it a landmark for polar science. But getting the samples was quite an achievement in itself, as researchers had to drill through meters of antarctic ice without contaminating Lake Whillans’ waters below.

  • Descubren cómo una proteína del virus Ebola bloquea la respuesta inmune temprana

    Francisco P. Chávez

      Una de las primeras respuestas del cuerpo humano a una infección viral es producir y liberar unas proteínas de señalización llamadas interferones, que amplifican la respuesta del sistema inmune a los virus. Con el tiempo, muchos virus han evolucionado para debilitar esta señal de estimulación inmunológica del interferón. En un artículo publicado en la prestigiosa revista Cell Host & Microbe se describe un mecanismo único del virus Ébola para bloquear los intentos del interferón para bloquear la reproducción del virus en las células infectadas.     El recién…

    The news was full of the discovery that taking some aspirin every day for ten years could somehow reduce your risk of getting cancer, particularly cancers of the gastrointestinal tract. The stomach bleeding side-effect (for some) and other as yet unknown side-effects aside, I was skeptical from the start, it just looked like a review of reviews where they looked at the idea that taking aspirin for years and years might somehow correlate with not getting cancer. To me, this is like the inverse of so many other studies that purportedly “prove” that such and such an exposure to food,…

    Biology concepts – lipid, saturation, fruit, vegetable, drupe, berry, mesocarp, cotyledon, tuber, fatty acid, triglyceride To try and get blood from a stone dates back to the 1600’s, meaning to try and do the impossible. It was first used in a book by Giovanni Toriano called The Second Alphabet. As far as the turnip goes, it may relate to a story in the Bible of Cain and Abel making sacrifices – one a vegetable and one an animal. The vegetable sacrifice was not as appropriate since it could not drip blood. Now we often use the phrase for the inability of getting someone to pay money.Did…

    A potential vaccine against the Zaire species of Ebola, which has currently claimed 1,550 lives in West Africa, is to be tested on healthy patients in the UK and US. The candidate vaccine has been fast-tracked by an international consortium and will be tested on 60 healthy volunteers at the University of Oxford’s Jenner Institute once ethical and regulatory approval is granted. The safety trial will run alongside a similar trial in the US, and if volunteers show a good response, it will – subject to approval – be rolled out to a further 40 volunteers in an MRC Unit in the Gambia, and…
  • Epigenetic changes play role in Alzheimer’s

    28 Aug 2014 | 2:05 am
    Researchers say they have amassed some of the strongest evidence yet to show that epigenetic changes have a role to play in Alzheimer’s disease. Researchers from King’s College London and the University of Exeter have found that chemical modifications to DNA within the ankyrin or ANK1 gene is strongly associated with measures of neuropathology in the brain. Researchers performed cross tissue analysis of methylomic variation in Alzheimer’s disease in samples from four independent human post-mortem brain cohorts. They analysed three cortical regions, the cerebellum and blood from several…
  • Van der Waals prevents asteroid spinning apart

    27 Aug 2014 | 12:00 am
    A near-Earth asteroid rotates so quickly that it defies gravity and is held together by van der Waals cohesive forces, a phenomenon never before seen on an asteroid. Researchers from the University of Tennessee made the discovery while monitoring asteroid 1950 DA and say their work could protect the world from future collisions with asteroids. Previous research has shown asteroids are loose piles of rubble held together by friction and gravity, but researchers in the Department of Earth and Planetary Sciences wanted to find out what stops the body from breaking apart.

  • Ancient shellfish provide clues to El Niño history

    22 Aug 2014 | 12:00 am
    New insight into the El Niño Southern Oscillation has been provided by 25-foot piles of ancient shellfish remains. Researchers analysing the shells have found El Niños 10,000 years ago were as strong and frequent as the ones experienced today. Their results call into question the accuracy of computer models to reproduce historic El Niño cycles, and predict how they might change under future climates. “We thought we understood what influences the El Niño mode of climate variation, and we’ve been able to show that we actually don’t understand it very well,” said Julian Sachs,…
  • Self-assembly robots that walk away

    21 Aug 2014 | 12:00 am
    A combination of origami and electronic engineering has led to the development of a robot that simply folds itself up and walks away. Using paper and polystyrene, researchers from Harvard School of Engineering and Applied Sciences (SEAS) have built a robot that assembles itself in to a complex shape in just four minutes, and then scurries away without any human intervention. Described in Science, the technology demonstrates the potential to quickly and cheaply build sophisticated machines, automating much of the design and assembly process. “Getting a robot to assemble itself autonomously…

    28 Aug 2014 | 9:00 am
    Until the last few decades, the frontal lobes of the brain were shrouded in mystery and erroneously thought of as nonessential for normal function—hence the frequent use of lobotomies in the early 20th century to treat psychiatric disorders. Now a review publishing August 28 in the Cell Press journal Neuron highlights groundbreaking studies of patients with brain damage that reveal how distinct areas of the frontal lobes are critical for a person’s ability to learn, multitask, control their emotions, socialize, and make real-life more

This signaling pathway is regulated by a gene, called neurofibromatosis type 1 (Nf1), which TSRI scientists found is linked with excessive drinking in mice. The new research shows Nf1 regulates gamma-aminobutyric acid (GABA), a neurotransmitter that lowers anxiety and increases feelings of more

There are a number of different theories about the problem (although nothing has been agreed upon yet), including pesticide use, fungal infection, and disease. What many of the stories have failed to note, however, is that bee populations were in trouble before the disorder made headlines.

    The United States and most of the rest of the developed world enjoy very high vaccination rates for routine childhood illness — typically over 90 percent. But in the last decade or two, these vaccination rates have stagnated and even declined in some locations. The measles vaccination coverage in the United Kingdom, for example, went from a high of 92 percent in the mid-1990s to just 81 percent by the mid-2000s (it has since recovered). Poor countries often can’t achieve complete vaccination because of cost, but non-universal vaccination in the developed world is more often a…

    Try as we might, we simply, can’t beat the speed of light: 186,000 miles per second. That’s the cosmic speed limit, imposed on us by the immutable equation, E=mc². Yet, most “ships of the imagination”—to borrow a phrase from Neil deGrasse Tyson—invented by science-fiction writers and Hollywood screenwriters, continue to enthrall us with their ability to travel at superluminal speeds, making journeys from one star system to another look like milk-runs. So, what gives? What happens is that they only appear to travel faster than light. The spacecraft, themselves, don’t generate…
  • Learning to be helpless

    25 Aug 2014 | 10:00 am
    Learned helplessness is the term for essentially giving up hope for escape from an adverse situation or stimuli even when the chance to alleviate the suffering presents itself. After being subjected to an aversive or painful stimuli for a prolonged period of time (negative emotions during depression or animals receiving electric shocks in a lab experiment for example) the person or animal has come to accept that it cannot control the situation, gives up all hope and offers no resistance to the negative situation. In a nutshell, by becoming so accustomed to the suffering it sees no way out and…

    Viputheshwar SitaramanFounder, BloggerDraw Science.For some reason, it seems scientists feel they’re too good for social media. Apparently, the traditional dogmatic, restricted, and expensive dissemination of research via academic journals is far superior to the hyper-efficient, rapid, and completely free spread of knowledge via social media. Apparently, burying a new research article amongst hundreds of issues of one among thousands of journals in one among millions of scientific fields generates more attention than broadcasting it right to the smartphones, tablets and computers of…

  • Nanokids and Nanoprofessionals

    Anupum Pant
    1 Sep 2014 | 10:35 am
    By Anupum Pant In the year 2003, a group of researchers headed by James Tour at Rice university designed and synthesized a series of organic molecules that they thought would get kids interested in chemistry. These organic molecules resembled human figures and were named Nanoputians - A portmanteau of nanometer (a unit of length used to measure extremely tiny distances) and Lilliputian (the tiny human-like fictional characters from Gulliver’s travels). The synthesized nanokid molecule basically consisted of two benzene rings and a couple of carbon atoms for its body. For the…
  • Wilson Primes

    31 Aug 2014 | 10:35 am
    By Anupum Pant Thanks to the guys at Numberphile for introducing me to Wilson primes. Although the piece of information that describes Wilson primes itself has more or less no practical use, I still think it’s a good thing to know. The first thing you need to know is that all prime numbers follow this rule – If you take a prime number P and put it in the following equation you get a number that is perfectly divisible by the prime number P. The equation: (P − 1)! + 1 = Q Note: ! is a sign used for factorial. That means P! is equal to the product of all natural numbers smaller or…
  • Pseudoscorpions

    30 Aug 2014 | 10:35 am
    By Anupum Pant I had never heard of these creatures before. A couple of days back when I learnt about them, I was totally fascinated. Psuedoscorpions are teeny tiny bugs that look a lot like scorpions. They are also popularly known as false scorpions or book scorpions. False because they aren’t really scorpions, and they don’t even have stingers like scorpions do. They do have those scorpion like claws. Book scorpions because they are often found in old dusty books. Psuedoscorpions are very tiny. They are about one tenth of an inch long. Here’s is a comparison of it with a…
  • The Northern Clingfish Can Really Suck

    29 Aug 2014 | 10:35 am
    By Anupum Pant The Northern Clingfish, an ugly fish the size of your hand, is a relatively tiny creature which can lift really heavy weights. No wait, it doesn’t really lift weights. This fish has fused pectoral and pelvic fins which form a complete disc like structure under it which enables it to stick to some of the most rough and most wet surfaces. Thanks vacuüm. The suction cup under it doesn’t need any live muscles to work. Even a dead Northern Clingfish can suck as good as a live one. Look at how the suction cups under a 0.5 lb Northern Clingfish can hold a 6 lb rock for a…
  • The Largest Object in the Solar System

    By Anupum Pant On November 6th 1892, after being spotted by a British astronomer Edwin Holmes, comet Holmes was not seen again for several decades. Thus it came to be known as the lost comet. Out of the blue, more than 70 years later, the comet was again seen in the year 1964. Now it is known that comet Holmes was captured by Jupiter several thousand years ago, and it never went back to the Kuiper belt. It is a Jupiter family comet. Every 6.88 years, the comet orbits the sun. Even this year, on 27th of March, it was one of the most bright comets of the year. But it was something that…

  • A p38 Blocking Drug Rejuvenates Aged Immune Systems

    1 Sep 2014 | 5:35 pm
    According to two new studies released by researchers at the University College of London, it may be possible to slow or reverse the aging of the immune system, specifically in a type of cells known as T lymphocytes. Both studies uncovered evidence that the ultimate fates T lymphocytes are controlled by a molecule known as p38. By shutting down p38, the researchers could bring deactivated T lymphocytes that have gone into a hibernating-like state called “senescence” back into a state characterized by cell division and proliferation. The protein p38, is a member of a pathway belonging to…
  • Desert Plant Derives Up To 90% Of Water-Intake From Gypsum Rock

    31 Aug 2014 | 7:54 pm
    Plant physiologists have discovered that the shallow rooted desert plant Helianthemum squamatum, derives up to 90% of its fluid requirements from crystallization water trapped in gypsum rock.  The finding represents a completely new kind of water source for life. The team of researchers, led by primary author Dr. Sara Palacio of the Instituto Pirenaico de Ecología in Spain, and senior author Dr. Juan Pedro Ferrio of the University of Lleida exploited differences in gypsum water and free soil water.  The two kinds of water differ in their amounts of hydrogen and oxygen isotopes.  By…
  • Massive Early Galaxy And Stellar Nursery Caught During Core-Formation For The First Time

    30 Aug 2014 | 8:30 pm
    A team of astronomers led by PhD student Erica Nelson of Yale University and Postdoctoral Fellow Stijn Wuyts of the Max Planck Institute for Extraterrestrial Physics have discovered a giant galaxy in the initial stages of forming. The bustling star nursery is the densest ever seen, with millions of new stars forming at an incredible rate. A planet located in that region would never experience night, as the multitude of young stars would illuminate it all around through the clouds of dust and gas that fill the skies. The busy galactic core is about 6,000 light years across, but has twice the…
  • 2014 Ebola Outbreak Finally Traced To A Single Point Of Infection From Animal-To-Human

    29 Aug 2014 | 8:46 pm
    Researchers from the Broad Institute and MIT, in a burst of concentrated activity, have discovered that a single transmission from an animal source to a human is responsible for the current massive Ebola outbreak in West Africa that started in December of 2013 and continues to spread as of today.  Subsequent to this event, the researchers’ work suggests human to human transmission was responsible for further infection. The researchers reported in the publication Science today: Genetic similarity across the sequenced 2014 samples suggests a single transmission from the natural reservoir,…
  • Painless Electrical Stimulation Of The Ear Improves Heart Variability

    28 Aug 2014 | 8:45 pm
    A recent study lead by researchers at the University of Leeds reports that electrical impulses applied to the flap of the ear known as the tragus might be beneficial to hearts afflicted with disease.  The device used to apply electric pulses to the tragus is known as the TENS machine, and has bee used in the past to treat labor pains. Professor of Systems Neuroscience Jim Deuchars in the University of Leeds’ Faculty of Biological Sciences explains that applying a stimulus from the Transcutaneous Electrical Nerve Stimulation, or TENS, unit to the tragus is painless and has the potential…

  • 6 Organisms That Can Survive The Fallout From A Nuclear Explosion

    Morgans Lists
    29 Aug 2014 | 2:13 pm
    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…

    Panspermia is the theory that life spreads throughout the universe from planet to planet, and solar system to solar system. Distributed by meteoroids, asteroids, comets, and even through spacecraft via unintended contamination from alien contact. For example, during an Apollo mission to the moon there was a stowaway, the common bacteria Streptococcus mitis, took a walk on the moon with the astronauts and lived to return home and tell it's tale. In 1991, Apollo 12 Commander Pete Conrad commented on the significance of the only known microbial survivor of harsh interplanetary travel:"I always…
  • 8 Pieces of Crazy and Unconventional Performance Art

    Morgans Lists
    25 Aug 2014 | 10:08 am
    Performance art challenges accepted conventions and traditional forms of visual art such as painting and sculpture. Sometimes performance art focuses on the human body as it's canvas through movement, dance, or actions and activity not usually associated with art. It is normally presented live by the artist and their collaborators and sometimes with hired performers. Recently, performance art is becoming more and more unusual as the bounds of conventionality are stretched further and further to shock audiences and enable new artists to make a name for themselves. Here is 8 pieces of crazy and…
  • What Did Ancient Greek Music Sound Like? - Listen Here

    David Creese of the University of Newcastle plays an ancient Greek song taken from stone inscriptions constructed on an eight-string "canon" (a small stringed instrument) with movable bridges. (Audio file is ©BBC)Music is a part of human nature, and evidence of musical instruments shows up consistently in the archaeological record. We can track the first flute-like instrument all the way back to the Neanderthals. The ancient Greeks played their music on stringed instruments like a zither or the lyre as well as reed pipes, and percussion mediums. We know about the use of some of these…
  • 5 Animals That May Prove The Male Sex Is A Product Of Evolution

    The Bible tells us we were formed in God's image. So if a person believes in the Bible and takes it literally, but also believes in some science or the laws of the natural world. Then how would they reconcile their two beliefs if science were to prove the female of the species, of all species, came first? Many have asked the question, "Exactly which of our two visages is it, male or female, that came first?" Maybe both, or does just one of the sexes contain all the components we need? It is similar to the question "Did the chicken come first, or the egg?" But instead the…

Artificial intelligence is about to outpace human ability, according to Dave Coplin, a senior Microsoft executive. Computers will not only be able to undertake complex mathematical equations but draw logical, nuanced conclusions, reducing the need for human interference, he said. This will render certain professions redundant, while other “human only” skills will become increasingly valuable. Subject:  Artificial Intelligence
