  • Toddlers have ‘an ear’ for accents

    Dominic Ali-Toronto
    17 Apr 2014 | 12:16 pm
    By two years of age, children are remarkably good at comprehending speakers who talk with regional accents that the toddlers have never heard before. Even more striking, say researchers, children as young as 15 months who have difficulty comprehending accents they’ve never heard before can quickly learn to understand accented speech after hearing the speaker for a short time.

    The proportion of land used to cultivate shade-grown coffee, relative to the total land area of coffee cultivation, has fallen by nearly 20 percent globally since 1996. The global shift toward a more intensive style of coffee farming is probably having a negative effect on the environment, communities, and individual farmers, researchers say.

    Scientists have discovered that fruit flies regulate their flight speed by using both vision and wind-sensing information from their antennae. Michael Dickinson, professor of bioengineering at California Institute of Technology (Caltech) is interested in how such tiny insects are capable of something we humans can only dream of: autonomous flight. In a report on a recent study that combined bursts of air, digital video cameras, and a variety of software and sensors, Dickinson and his team explain a mechanism for the insect’s “cruise control” in flight—revealing a…

    Mercury levels in excess of U.S. Environmental Protection Agency health thresholds for potential impacts to fish, birds, and humans have been detected in fish in some of the most remote national park lakes and streams in the western United States and Alaska. Mercury is harmful to human and wildlife health. It arises from natural sources, such as volcanic eruptions, and from human sources such as burning fossil fuels in power plants. Mercury is distributed at local or regional scales as a result of current and historic mining activities. Human activities have increased levels of…

  • Malaria Pathogen's Cellular Skeleton Gets A Super-Microscope Look

    News Staff
    17 Apr 2014 | 7:19 pm
    The tropical disease malaria is caused by the Plasmodium parasite. For its survival and propagation, Plasmodium requires a protein called actin. Scientists of the Helmholtz Centre for Infection Research (HZI) in Germany used high-resolution structural biology methods to investigate the different versions of this protein in the parasite in high detail. Their results may in the future contribute to the development of tailor-made drugs against malaria–a disease that causes more than half a million deaths per year. read more
  • Better Thermal-imaging Lens From Waste Sulfur

    News Staff
    17 Apr 2014 | 7:19 pm
    Sulfur left over from refining fossil fuels can be transformed into cheap, lightweight, plastic lenses for infrared devices, including night-vision goggles, a University of Arizona-led international team has found. The team successfully took thermal images of a person through a piece of the new plastic. By contrast, taking a picture taken through the plastic often used for ordinary lenses does not show a person's body heat. "We have for the first time a polymer material that can be used for quality thermal imaging – and that's a big deal," said senior co-author Jeffrey Pyun, whose lab at…

    A contact on Twitter mentioned an apparently newly discovered parasitic disease which goes by the name of Protomyxzoa Rheumatica or the “Fry bug”, named for its apparent discoverer Fry Laboratories of Scottsdale, Arizona. The discoverers have published no scientific papers about this organism as far as I can tell. Although protomyxzoa.org (registered in September 2012) says Fry has a PCR test for the pathogen and the person running the site says they were diagnosed by the labs in February of that year.

  • How the Brain Decides When to Work and When to Rest: Dissociation of Implicit-Reactive from Explicit-Predictive Computational Processes

    Florent Meyniel et al.
    17 Apr 2014 | 2:00 pm
    by Florent Meyniel, Lou Safra, Mathias Pessiglione A pervasive case of cost-benefit problem is how to allocate effort over time, i.e. deciding when to work and when to rest. An economic decision perspective would suggest that duration of effort is determined beforehand, depending on expected costs and benefits. However, the literature on exercise performance emphasizes that decisions are made on the fly, depending on physiological variables. Here, we propose and validate a general model of effort allocation that integrates these two views. In this model, a single variable, termed cost…

    by Laetitia Canini, Jessica M. Conway, Alan S. Perelson, Fabrice Carrat Several studies have proven oseltamivir to be efficient in reducing influenza viral titer and symptom intensity. However, the usefulness of oseltamivir can be compromised by the emergence and spread of drug-resistant virus. The selective pressure exerted by different oseltamivir therapy regimens have received little attention. Combining models of drug pharmacokinetics, pharmacodynamics, viral kinetics and symptom dynamics, we explored the efficacy of oseltamivir in reducing both symptoms (symptom efficacy) and viral load…
  • Computational Prediction of Alanine Scanning and Ligand Binding Energetics in G-Protein Coupled Receptors

    Lars Boukharta et al.
    17 Apr 2014 | 2:00 pm
    by Lars Boukharta, Hugo Gutiérrez-de-Terán, Johan Åqvist Site-directed mutagenesis combined with binding affinity measurements is widely used to probe the nature of ligand interactions with GPCRs. Such experiments, as well as structure-activity relationships for series of ligands, are usually interpreted with computationally derived models of ligand binding modes. However, systematic approaches for accurate calculations of the corresponding binding free energies are still lacking. Here, we report a computational strategy to quantitatively predict the effects of alanine scanning and ligand…

  • Evolutionarily Diverged Regulation of X-chromosomal Genes as a Primal Event in Mouse Reproductive Isolation

    Ayako Oka et al.
    17 Apr 2014 | 2:00 pm
    by Ayako Oka, Toyoyuki Takada, Hironori Fujisawa, Toshihiko Shiroishi Improper gene regulation is implicated in reproductive isolation, but its genetic and molecular bases are unknown. We previously reported that a mouse inter-subspecific X chromosome substitution strain shows reproductive isolation characterized by male-specific sterility due to disruption of meiotic entry in spermatogenesis. Here, we conducted comprehensive transcriptional profiling of the testicular cells of this strain by microarray. The results clearly revealed gross misregulation of gene expression in the substituted…

  • Epigenetic Regulation by Heritable RNA

    Reinhard Liebers et al.
    17 Apr 2014 | 2:00 pm
    by Reinhard Liebers, Minoo Rassoulzadegan, Frank Lyko Genomic concepts are based on the assumption that phenotypes arise from the expression of genetic variants. However, the presence of non-Mendelian inheritance patterns provides a direct challenge to this view and suggests an important role for alternative mechanisms of gene regulation and inheritance. Over the past few years, a highly complex and diverse network of noncoding RNAs has been discovered. Research in animal models has shown that RNAs can be inherited and that RNA methyltransferases can be important for the transmission and…

  • IL-3 and CSF-1 Interact to Promote Generation of CD11c+ IL-10-Producing Macrophages

    Kuo-Ching Sheng et al.
    17 Apr 2014 | 2:00 pm
    by Kuo-Ching Sheng, Lara J. Herrero, Adam Taylor, Andrew J. Hapel, Suresh Mahalingam Unraveling the mechanisms of hematopoiesis regulated by multiple cytokines remains a challenge in hematology. IL-3 is an allergic cytokine with the multilineage potential, while CSF-1 is produced in the steady state with restricted lineage coverage. Here, we uncovered an instructive role of CSF-1 in IL-3-mediated hematopoiesis. CSF-1 significantly promoted IL-3-driven CD11c cell expansion and dampened basophil and mast cell generation from C57BL/6 bone marrow. Further studies indicated that the CSF-1/CSF-1R…
  • Regulator of G Protein Signaling 2 (RGS2) and RGS4 Form Distinct G Protein-Dependent Complexes with Protease Activated-Receptor 1 (PAR1) in Live Cells

    Sungho Ghil et al.
    17 Apr 2014 | 2:00 pm
    by Sungho Ghil, Kelly L. McCoy, John R. Hepler Protease-activated receptor 1 (PAR1) is a G-protein coupled receptor (GPCR) that is activated by natural proteases to regulate many physiological actions. We previously reported that PAR1 couples to Gi, Gq and G12 to activate linked signaling pathways. Regulators of G protein signaling (RGS) proteins serve as GTPase activating proteins to inhibit GPCR/G protein signaling. Some RGS proteins interact directly with certain GPCRs to modulate their signals, though cellular mechanisms dictating selective RGS/GPCR coupling are poorly understood. Here,…

Ahsan, Xavier Alvarez, Tianhua Niu, Deepak Kaushal Mycobacterium tuberculosis (Mtb) persists within lung granulomas, despite being subjected to diverse stress conditions, including hypoxia. We hypothesized that the response of host phagocytes to Mtb experiencing hypoxia is radically altered and designed in vitro experiment to study this phenomenon. Hypoxia-stressed (Mtb-H) and aerobically grown Mtb (Mtb-A) were used to infect Rhesus Macaque Bone Marrow Derived Macrophages (Rh-BMDMs) and the comparative host response to Mtb infection studied.

  • Identification of cis-Acting Elements and Splicing Factors Involved in the Regulation of BIM Pre-mRNA Splicing

    Wen Chun Juan et al.
    17 Apr 2014 | 2:00 pm
    by Wen Chun Juan, Xavier Roca, S. Tiong Ong Aberrant changes in the expression of the pro-apoptotic protein, BCL-2-like 11 (BIM), can result in either impaired or excessive apoptosis, which can contribute to tumorigenesis and degenerative disorders, respectively. Altering BIM pre-mRNA splicing is an attractive approach to modulate apoptosis because BIM activity is partly determined by the alternative splicing of exons 3 or 4, whereby exon 3-containing transcripts are not apoptotic. Here we identified several cis-acting elements and splicing factors involved in BIM alternative splicing, as a…

    If you sensibly use a password manager, whether an online (LastPass) or offline (KeyPass) tool you will probably have heard of the security bug that was uncovered in OpenSSL, the encryption system that underpins security on countless websites. The bug, which goes by the catchy name of HeartBleed, has now been demonstrated as problematic for much of the web and the recommendation is that you change your passwords urgently. But, how do you know which site to reset first? Lastpass has usefully added a scan to their security tools that will work through all your registered logins and tell you…

    17 Apr 2014 | 3:40 am
    As a lesson on conditional probability for himself, Walt Hickey watched 403 episodes of "The Joy of Painting" with Bob Ross, tagged them with keywords on what Ross painted, and examined Ross's tendencies. I analyzed the data to find out exactly what Ross, who died in 1995, painted for more than a decade on TV. The top-line results are to be expected — wouldn't you know, he did paint a bunch of mountains, trees and lakes! — but then I put some numbers to Ross's classic figures of speech. He didn't paint oaks or spruces, he painted "happy trees." He favored "almighty mountains" to…

  • Five decades of warm and cold weather anomalies

    14 Apr 2014 | 8:18 am
    This year's polar vortex churned up some global warming skeptics, but as we know, it's more useful to look at trends over significant spans of time than isolated events. And, when you do look at a trend, it's useful to have a proper baseline to compare against. To this end, Enigma.io compared warm weather anomalies against cold weather anomalies, from 1964 to 2013. That is, they counted the number of days per year that were warmer than expected and the days it was colder than expected. An animated map leads the post, but the meat is in the time series. There's a clear trend towards more warm.

    Elizabeth Pennisi
    17 Apr 2014 | 5:00 pm
    Using the two high-quality genomes that exist for Neandertals and Denisovans, researchers find clues to gene activity in these long-gone species by computationally mapping where a chemical modification called methylation occurred in the DNA during the lifetime of the individual. The method takes advantage of how DNA degrades through time. When compared with methylation in modern humans, these methylation maps revealed a possible explanation for the skeletal differences between Neandertals and modern humans. Many more ancient methylomes must be mapped to determine which methylome is…

    Astronomers have discovered an Earth-sized planet in the habitable zone of a red dwarf—a star cooler than the sun—500 light-years away. Because such stars make up three-quarters of all stars in the Milky Way, the finding could open a wide new hunting ground for extraterrestrial life. Author: Yudhijit Bhattacharjee

  • The Health Risks of Wearing A Bra

    theghostwriter
    12 Apr 2014 | 8:23 pm
    Recent research studies have shown that women might actually be putting their health at risk by wearing a bra. As shocking as this may sound, it is true. What sort of health risks are we talking about? Well, women who wear a bra have been found to be more prone to suffer from frequent breast pain, and even breast cancer in the long run. Research based evidence The one thing that needs to be mentioned here is that there is growing evidence that women who belong to cultures that do not deem it necessary for them to wear bras do not largely suffer from breast cancer. A number of researches have…
  • The Health Benefits of Bra

    theghostwriter
    29 Mar 2014 | 7:09 pm
    With the passage of time, experts have come to the conclusion that the breasts of a woman continue to change sizes all through life. On average, it is believed by experts that breasts have the potential to change sizes an average of five times throughout the life of a woman. What would that mean for a woman? Well, to begin with, this means that the bra that you are wearing at the moment will not be a perfect fit in years to come. You would need to purchase a new bra to make sure that it fits you well. If truth be told, all this can easily happen in just a year’s time so you need to keep an…
  • Who Invented The First Bra?

    theghostwriter
    15 Mar 2014 | 7:08 pm
    Bras, as we all know, are commonly worn by women across the world. However, what do we know about this clothing item’s history? Who invented it? Well, let’s help you learn about its history a bit. The very first modern brassiere to have ever received a patent was the one that was invented by Mary Phelps Jacob, a New York socialite in the year 1913. Details about the invention of bras The events that lead to the invention of the first bra are rather interesting. What basically happened is that Mary Phelps Jacob had recently bought an exquisite looking evening gown that she wanted to wear…
  • Cats vs Dogs Superpower: Ultraviolet Vision

    WTJ
    22 Feb 2014 | 7:25 pm
    When I read the report that house pets are able to see UV lights that human can’t see, I immediately thought of howling dogs.  One of the superstitious belief that dogs cried when they see or sense supernatural figure, such as ghosts or spirits.  Although scientists believe that dogs howl to have long-range communication with other dogs, it is also proven they howl because of anxiety. Back to the topic, with the ‘superpower’ of seeing ultraviolet wavelengths, the house pets are able to see dried puddles or urine (or sperm stain) which are usually used by animals in marking…

  • Western Blot, ELISA or PCR; which technique should I use?

    Ellen Moran
    17 Apr 2014 | 2:54 am
    A pretty standard experiment in a molecular biology laboratory is where a scientist stimulates some cells/tissue with a stimulus of interest i.e. cytokine. They can then analyse the cellular response to the external stimulus and investigate what intracellular signalling pathways have been activated/deactivated or what proteins have been secreted from the cell as a result. There are a number of different methods that can used to analyse such responses. The most appropriate method depends on what aspect of the response being analysed and what questions you are asking as a researcher. The…
  • When Glycogen is not Your Friend – Isolating RNA from Glycogen-Rich Tissues

    Suzanne Kennedy
    16 Apr 2014 | 12:00 am
    Bitesize Bio has had a lot to say about RNA isolation, mainly because it is one of the most anxiety-producing requirements for molecular biology; especially when you are first starting out (although isolating proteins from complex samples like soil and stool is far more difficult, let me tell you.  But that’s a future post.)  We’ve discussed how to work RNase-free, how to troubleshoot your preps, how to check the purity of your RNA preps and 5 ways to really screw things up (in case you weren’t sure). Well, recently we were asked about isolating RNA from a very specific tissue type…
  • Verhoeff-van Gieson Stain: A Special Histology Stain for Elastic Fibers

    Nicola Parry
    15 Apr 2014 | 3:00 am
    What is Verhoeff-van Gieson’s stain? Ira Van Gieson first described the Verhoeff-van Gieson (VVG) staining protocol in 1889 as a method of evaluating collagen fibers in neural tissue. Frederick Herman Verhoeff, an American surgeon and pathologist, then modified the stain in 1908, as a method to differentiate collagen and other connective tissues, and highlight elastic fibers in particular. What does it stain? Elastic fibers are connective tissue fibers that allow tissues to stretch, and are abundant in the aorta, for example, where they provide flexibility to this large blood vessel.  They…

You have your Co-immunoprecipitation (Co-IP) elution… Now what? Well, you have a few choices. It really all depends on what you need know about the proteins in your elution. Do you need to identify the proteins in your elution? Or merely confirm their presence?  Do you need to know how the proteins have changed with a treatment? Read below to learn what you…
  • Herzenberg and the Invention of the FACS Machine

    Catriona Paul
    15 Apr 2014 | 12:00 am
    The flow cytometer that we have all grown to know and love may have only come into its own in the 1990’s, but who would have known that the first cell sorter was invented as early as the 1950’s? With the recent death of one of the key developers of fluorescence activated cell sorting (FACS), Leonard Herzenberg, it seems like a good time for an article revisiting his contributions to the invention of the FACS* machine. But first, we’ll start with a quick overview of the process before we delve into the history lesson. A quick overview of FACS FACS is a specialized type of flow cytometry…

  • Scientists discover the animal kingdom’s first ‘female penis’

    Mihai Andrei
    17 Apr 2014 | 4:17 pm
    A female insect has developed a spiky penis which it uses to get in charge . It’s a role reversal, basically: not only do the females have a penis, but the males have a vagina. The males still have sperm, but the female extracts it from the male vagina using its penis. Sounds strange, doesn’t it? Researchers thought so too. When Neotrogla curvata insects mate, the female (top) penetrates the male. What is the decisive factor when it comes to deciding if some animal is a male or a female? Hint: it’s not the existence or absence of genitalia. Another hint: it’s not even…

  • ‘The Temptation of Despair’

    17 Apr 2014 | 1:49 pm
    It is one thing to survive a war — a consequence of luck, perhaps, or skill. It is another thing to survive the aftermath of a war — an interval marked by death, ruin, guilt, the irony of survival itself, and the hubris of the triumphant that follows an uneasy peace. War’s aftermath, in this case the late 1940s in Germany, is the subject of a new book by Werner Sollors, “The Temptation of Despair,” out this month under the Belknap Press imprint of Harvard University Press. The author, who was a child in the ruins of the Germany he describes, spoke Wednesday night in Sever Hall…
  • MRI, on a molecular scale

    17 Apr 2014 | 1:02 pm
    For decades, scientists have used techniques such as X-ray crystallography and nuclear magnetic resonance (NMR) imaging to gain invaluable insight into the atomic structure of molecules. Such efforts have long been hampered by the fact that they demand large quantities of a specific molecule, often in ordered and crystalized form, to be effective — making it all but impossible to peer into the structure of most molecules. Harvard researchers say those problems may soon be a thing of the past. A team of scientists, led by Professor of Physics and of Applied Physics Amir Yacoby, has developed…

    Drawing on the experience of four nations, experts described how crises and fundamental transitions often prove the catalysts behind universal health care systems during a panel event Tuesday at Harvard’s Longwood campus. In Turkey, it took an earthquake and thousands of deaths to galvanize reform of an unequal system. For Mexico and Thailand, it took a democratic transition, coupled with constitutional guarantees of citizens’ right to health care. In China, it took an outbreak of SARS — and the global attention that accompanied it — to call attention to the flaws in a market-based…

  • Art and Science: Two Parts of a Whole

    15 Apr 2014 | 7:00 am
    By Michal Meyer Are art and science ying and yang, essential yet opposite parts of our world? We can trace the origins of material science to the first cave drawings made thousands of years ago. The artists who left these pictures likely began with trial and error attempts made with burned wood and colored dirt. Even then art and science were mingling, taking physical form through pigment. Art and science also meet in fascinating ways in the Dutch alchemical paintings that were so popular in the 17th century. Not only did these paintings show alchemists at work, they required the skills of…

  • Reflecting on Experiences as a NIDA Fall Intern

    Carl M. Letamendi, M.B.A., Ph.D. (ABD)
    16 Apr 2014 | 6:41 am
    I am finishing my Ph.D. in May 2014 in a field housed under the umbrella of social sciences, called conflict analysis and resolution. The field provides the foundation and skills necessary to identify areas of conflict and resolve them without the need for taking legal action. The goal is to ensure that there is a win-win outcome for the parties in dispute. I have always been interested in conducting research in the field of health sciences as well and had planned to attend medical school after my Ph.D. program is complete. Last fall, I had a chance to intern with NIDA, where I had a…
  • Video Game Addiction—Is it Real?

    9 Apr 2014 | 5:54 am
    Doodle Jump. Candy Crush. FarmVille. Angry Birds. Cut the Rope. Fruit Ninja. Words With Friends. Nearly everyone with a smartphone or tablet has played one of these video games. It’s easy to get swept up in the bright colors, cutesy characters—and the satisfaction you feel when you finally complete a difficult level. So you keep playing, and playing, and playing. Lots of people say games like these are “addictive.” But, are they, really? Maybe. Addiction Science Award Winner Ethan Guinn definitely thought so.

  • The Connection Between Pain Medications and Heroin

    Sara Bellum
    2 Apr 2014 | 6:32 am
    More and more young people are using heroin these days, and sometimes they start using it because they’ve gotten addicted to prescription painkillers. One study showed that people who abuse painkillers like OxyContin are 19 times more likely to start using heroin. The study also found that 8 out of 10 people who started using heroin abused painkillers first. Heroin and painkillers belong to the same class of drugs: Opioids. Opioids attach to specific molecules called opioid receptors, which are found on nerve cells in the brain, spinal cord, intestines, and other organs. When painkillers or…
  • Legal Marijuana and Driving: A Public Safety Problem

    Sara Bellum
    26 Mar 2014 | 7:59 am
    When you’re driving down the highway at 60 miles per hour, you need a clear head. Driving while distracted by your phone or driving under the influence of alcohol both can lead to crashes and tragedy. Driving under the influence of marijuana is also dangerous, because of the way the drug affects the brain and body. Recent news reports have talked about how drugged driving crashes and deaths have surged since medical marijuana has become legal in more states. Now that marijuana is legal for those over age 21 in Colorado and Washington, the rates of drugged driving are likely to increase even…

    NIDA’s 2013 Monitoring the Future study reported that more than 20%—that’s 1 in 5—high school seniors have used a hookah to smoke tobacco. A hookah is a pipe that burns flavored tobacco and passes the smoke through water before it is inhaled. It can have one stem to smoke from, or several stems so multiple people can smoke from the same pipe. Hookah bars, frequently found near college campuses, are gaining popularity with young adults. The exotic flavors of “shisha” (a mixture of tobacco, molasses, and fruit used in hookahs) appeal to teens. There are dozens of flavors, including…

  • Cricket is a matter of life and death

    A guest post by Bernard KachoyanEver thought of batting as a life and death struggle against hostile forces? It always seemed that way when I batted. Well you might be more accurate than you think. The experience of a batsman can be described as a microcosm of life: when you go out to bat you are “born”, when you get out you “die”. But what happens when you are Not Out (NO)? More subtly, when you are Not Out you simply leave the sample pool, that is you live for a while then you stop being measured. In the parlance of statistics, this becomes “censored” data. In medical research…

    “This is really a tip-of-the-iceberg discovery,” said study co-author Jason Rowe, an astronomer at the SETI Institute in Mountain View, Calif., who spent a year analyzing data gathered by NASA’s Kepler Space Telescope that led to finding the planet known as Kepler-186f. "We can infer that other ones are likely to exist. And that’s going to be the job of future missions to find [them].” Scientists have discovered the alien planet, Kepler-186f, slightly bigger than Earth, in the habitable zone of its host star, a dim red dwarf star about 490 light-years from Earth, that might have…

    17 Apr 2014 | 7:14 am
    Geologists who analyzed 40 meteorites that fell to Earth from Mars unlocked secrets of the Martian atmosphere hidden in the chemical signatures of these ancient rocks. The results will help guide researchers’ next steps in understanding whether life exists, or has ever existed, on Mars and how water—now absent from the Martian surface—flowed there in the past. Their study shows that the atmospheres of Mars and Earth diverged in important ways very early in the 4.6 billion year evolution of our solar system.

    In geological terms, a “rift” is an area of Earth where the planet’s crust is separating from the mantle beneath. One of the most extensive rift systems is found in East Africa, where a series of large fissures in Earth’s crust appear. This area is known as the East African Rift System and geologists believe part of it will break off from the African continent within 10 million years and form a new ocean basin. Because of the tectonic activity in the region, East Africa is home to some of the world’s greatest lakes. Lake Nyasa Also called Lake Malawi, it is the third largest body of…

  • Científicos regeneran tejidos ortopédicos dentro del cuerpo humano

    Francisco P. Chávez
    3 Mar 2014 | 8:21 am
      Mediante la combinación de un material de andamiaje sintético con técnicas de suministro de genes, los investigadores de la Universidad de Duke están más cerca de ser capaces de generar cartílago de reemplazo donde más se necesita en el cuerpo humano. La reparación de los tejidos con células madre normalmente requiere la aplicación de grandes cantidades de proteínas del factor de crecimiento, una tarea que es muy cara y se vuelve difícil una vez que el material a desarrollarse se implanta dentro de un cuerpo. Sin embargo, en un nuevo estudio científicos encontraron una…
  • Regeneran células pilosas que son afectadas durante la sordera

    Francisco P. Chávez
    1 Mar 2014 | 7:47 am
      Una de las principales causas de la pérdida de la audición en los mamíferos es el daño a las células pilosas que detectan el sonido en el oído interno. Durante años, los científicos han pensado que estas células no son reemplazados una vez que se pierden, pero una nueva investigación que aparece en la revista Stem Cell Reports revela que el apoyo a las células en el oído se puede convertir en células pilosas en ratones recién nacidos. Si los hallazgos se pueden aplicar a otros mamíferos, pueden ayudar a estimular el reemplazo de células en los adultos humanos y para el…

      Las plaquetas, cuya función principal es la de evitar el sangrado, son vitales para el tratamiento de varias formas de trauma y enfermedades de la sangre. Sin embargo, en la actualidad sólo se pueden obtener a través de las donaciones de sangre. Recientemente investigadores informaron en la prestigiosa revista Cell Stem Cell que encontraron una manera de crear plaquetas sin la necesidad de la sangre donada, un avance que podría borrar la escasez de suministros y garantizar tratamientos de plaquetas para todos los pacientes que lo necesiten.   El suministro de las plaquetas…
  • ¿Por qué el chocolate negro es bueno para el corazón?

    27 Feb 2014 | 6:08 am
      Puede parecer demasiado bueno para ser cierto, pero el chocolate negro es bueno para usted y los científicos ahora conocen el por qué. El chocolate negro ayuda a restaurar la flexibilidad de las arterias y al mismo tiempo evita que las células blancas de la sangre se peguen a las paredes de los vasos sanguíneos. Tanto la rigidez arterial y blanco de adhesión celular de la sangre son factores conocidos que desempeñan un papel significativo en la aterosclerosis. Incluso, los científicos también encontraron que el aumento del contenido en flavonoides del chocolate oscuro no…

  • Animating life: bringing science to the YouTube generation

    Seán I. O’Donoghue, Group Leader at the Garvan Institute and OCE Science Leader at CSIRO
    16 Apr 2014 | 10:03 pm
    Telling science stories often involves explaining complex interactions between a cast of molecular “actors”, on a set smaller than the wavelength of light, so scientists are increasingly using animation to communicate such stories to the broader public. This is part of a global shift in how knowledge is communicated, reflected in the rapid rise of online video content – more than 1 billion people view videos on YouTube each month. It is important that key scientific discoveries and insights are communicated well in this new medium, especially when they can lead to improved health…
  • Searching underwater for MH370 is a shot in the dark

    Robin Robertson, Senior Lecturer at Australian Defence Force Academy
    16 Apr 2014 | 1:30 pm
    The ongoing search for missing flight MH370 has shown how finding objects such as debris on the ocean is difficult, but finding them underwater in the deep ocean is much more challenging. As of Tuesday, the search for the Malaysian Airlines Boeing 777 went underwater with the Bluefin-21 autonomous unmanned vehicle put into action. Already there have been problems on both days of operation, with the vehicle reaching its maximum operating depth of 4,500m. What data the search authorities were able to download from the vehicle’s first mission – which lasted only six hours – has been…
  • Fear not the hipster beard: it too shall pass

    Beards are back, baby! Juan Luis/Flickr If you haven’t been outdoors in a few years, you might not have noticed that beards are back. Back in such a big way that apparently many New York hipsters are paying north of US$8,000 for “facial hair transplants” to embellish their patchy beards. While the hipster subculture appears to be ground zero for the latest swerve toward beardedness, men who would not be seen dead in skinny jeans or thrift-shop cardigans are letting the whiskers grow in a way that hasn’t been fashionable for decades. Why are beards sprouting from the unlikeliest faces?
  • What are the chances that your dad isn't your father?

    Rob Brooks, Professor of Evolutionary Ecology; Director, Evolution & Ecology Research Centre at UNSW Australia
    15 Apr 2014 | 1:37 pm
    How confident are you that the man you call dad is really your biological father? If you believe some of the most commonly-quoted figures, you could be forgiven for not being very confident at all. But how accurate are those figures? Questions of paternity are built over the deepest well of human insecurity, for children searching to know who they are, for fathers wanting to know whose kids they are raising and for mothers uncertain about the strength of the bonds holding their families together. I consulted on an episode of SBS’s Tales of the Unexpected documentary series, “Who’s Your…

    A contact on Twitter mentioned an apparently newly discovered parasitic disease which goes by the name of Protomyxzoa Rheumatica or the “Fry bug”, named for its apparent discoverer Fry Laboratories of Scottsdale, Arizona. The discoverers have published no scientific papers about this organism as far as I can tell. Although protomyxzoa.org (registered in September 2012) says Fry has a PCR test for the pathogen and the person running the site says they were diagnosed by the labs in February of that year.

  • Do Water Pollution Tests Lead to "Dead Zones"?

    Robert McClure
    17 Apr 2014 | 7:00 am
    Photo Credit: Brenda Culler, ODNR Coastal Management Reported by Robert McClure, InvestigateWest Waterways across the country are beset by a disturbing pattern: Polluted water discharged from sewage treatment plants carries with it vast amounts of phosphorus and nitrogen, which are known as “nutrients.” The nutrients feed massive algae blooms. Those in turn spur the growth of microbes — teeny-tiny bugs — that suck out of the water the oxygen that’s needed by fish and other aquatic creatures. The result is aquatic “dead zones” like the one off the coast of Louisiana,…
  • Picturing the Invisible: A Conversation with Artist Chris Jordan

    Facts and figures may help us quantify our collective footprint on the world, but they don’t necessarily make us care about it. Spurred by this sense of detachment, photographic artist Chris Jordan struck out on an impassioned quest to imbue some of these cold, hard numbers with deeper meaning. If I allow myself to feel something for the subject that I’m working with, somehow that feeling is embedded in the image itself. Through photographs that are eye opening or heartbreaking — or both, Jordan depicts the collective impacts of human activities on our society and environment. In…

    10 Apr 2014 | 7:00 am
    Central Nebraska may look like nothing but flat cornfields from a car speeding down Interstate 80, but it’s an incredibly important stopover point for millions of migrating birds, whose wings and cries fill the skies each spring. One of the most studied and iconic of these species is the sandhill crane, which has been making this annual migration for centuries. Roughly 500,000 cranes travel through Nebraska in the spring, where they descend upon the shallow Platte River, its sandbars, and nearby wetlands to rest and feed before continuing north to breed. Cranes use these wet meadows to…

  • Refrigerant replacement highly toxic on combustion

    LaboratoryNews
    17 Apr 2014 | 12:00 am
    EU regulations suggest refrigerants in car air conditioning systems are replaced with a more environmentally friendly version, but scientists are urging a rethink after studies showed the recommended replacement releases toxic chemicals upon combustion. Guidelines suggests that R1234yf – 2,3,3,3-tetrafluropropene – should be used as the refrigerant in car air conditioning systems, replacing R-134a (1,1,1,2-tetrafluroethane). However, the compound is inflammable, and in the event of a fire, the cooling agent would form the highly poisonous carbonyl fluoride said researchers from…

    The presence of antidepressants in our aquatic ecosystem is threatening wildlife, affecting its behaviour and biological make-up. A researcher from the University of Portsmouth has discovered that lower than expected concentrations of the prescription drugs are necessary to cause these changes. Just as antidepressants affect hormones such as serotonin in the human brain, many biological functions within invertebrates are also under serotonin’s the control. “Many invertebrates such as amphipod shrimp become more active and increase their speed of movement while freshwater snails display…

    Scientists probing new materials for batteries have succeeded in producing uniform antimony nanocrystals which could one day be used as alternative anode materials in high-energy-density batteries. These nanocrystals are able to store large quantities of lithium and sodium ions, the ETH Zurich and EMPA researchers say in Nano Letters, making them suitable for rechargeable batteries. Sodium is of particular interest as a low-cost alternative to lithium. Antimony has long been regarded as a promising anode material for high-performance lithium-ion batteries thanks to its high charging capacity…

    The French are a great believer in non-artificial sex when it comes to cinema or any other place. And when it comes to erotic film projects from a French studio, you can be rest assured about the most steamy scenes shot, edited and produced in the most educated connoisseurs. For the squeamish, I must declare that enjoying French eroticism on film could take time.

    The lack of specific refugee legislation in India has led the government to adopt an ad-hoc approach to different refugee influxes. The status of refugees in India is governed mainly by political and administrative decisions rather than any codified model of conduct. The ad hoc nature of the Government’s approach has led to varying treatment of different refugee groups. Some groups are granted a full range of benefits including legal residence and the ability to be legally employed, whilst others are criminalized and denied access to basic social resources.

The study’s authors say mammograms have no survival benefit relative to physical breast exams and in fact lead to significant over-diagnosis. In their words: “The data suggest that the value of mammography screening should be reassessed.” Predictably, not everyone agreed with them.The debate over mammograms centers on two questions.

  • Filter that lets light only from one direction pass through

    16 Apr 2014 | 3:55 am
    A new filter lets light pass through — but only if it's coming from just the right angle. Here, a light ray coming in at the 1-o’clock position reflects off the filter. But the other beam streaks straight on through.Scientists have simply created a replacement reasonably diffusing screen that is exceptionally fastidious. Engineered from a stack of clear materials, it solely permits lightweight that comes from a specific direction. Everything else can simply mirror off of it.Such a tool may improve cameras by reducing glare from the sun. The new filter may increase the sensitivity of…
  • Direct Hydrocarbon Indicators

    15 Apr 2014 | 1:49 am
    Seismic Methods & Hydrocarbon DetectionExplorationists have long dreamed of a device or technique that they could use at the earth's surface to get direct indications of deeply buried hydrocarbons. Over the years, scientists, inventors, entrepreneurs -- and not a few eccentrics -- have used tools ranging from divining rods to gas sniffers to "black boxes" in pursuit of this dream. They've analyzed soil samples, studied vegetation and taken pictures of the earth. They've walked, driven, flown and even sent up satellites. But their efforts have generally gone unrewarded. True, there are…
