  • His pain and her pain may not be the same

    Chris Chipello-McGill
    29 Jun 2015 | 1:28 pm
    Males and females process pain using different cells, a new study with mice suggests. The findings could help researchers develop the next generation of medications for chronic pain—the most prevalent health condition humans face. “Research has demonstrated that men and women have different sensitivity to pain and that more women suffer from chronic pain than men, but the assumption has always been that the wiring of how pain is processed is the same in both sexes,” says co-senior author Jeffrey Mogil, professor of pain studies at McGill University and director of the Alan…
  • Method spots colorectal cancer in tiny tissue sample

    Kimm Fesenmaier-Caltech
    29 Jun 2015 | 12:48 pm
    A new sensitive technique can detect colorectal cancer in tissue samples—a method that could one day be used in clinical settings for early diagnosis. Late detection is one of the reasons the disease is so deadly, killing about 700,000 people every year. “Currently, the average biopsy size required for a colorectal biopsy is about 300 milligrams,” says Ariel Furst, a graduate student at the California Institute of Technology (Caltech). “With our experimental setup, we require only about 500 micrograms of tissue, which could be taken with a syringe biopsy versus a punch…
  • Textbooks got it wrong: How your brain understands words

    Marla Paul-Northwestern
    29 Jun 2015 | 10:57 am
    For 140 years, scientists’ understanding of language comprehension in the brain came from individuals with stroke. Based on language impairments caused by stroke, scientists believed a single area of the brain—a hotdog-shaped section in the temporal lobe of the left hemisphere called Wernicke’s region—was the center of language comprehension. Wernicke’s was thought to be responsible for understanding the meaning of single words and sentences, two separate and critical functions. “There was some disconnect between what textbooks said and what we saw in our…

    After astronomer Steve Kawaler read an August 2010 New York Times article that questioned the timing of the famous Alfred Eisenstaedt photo of a sailor kissing a nurse in Times Square on V-J Day 1945, he sent a note to Donald Olson, a colleague in Texas. Olson has built a reputation as a sleuth who uses astronomical clues in paintings and photos to solve mysteries about the art. Kawaler, an Iowa State University professor of physics and astronomy, wrote to Olson about that New York Times story and speculation in the reader comments that a shadow on a building behind the kissers might…

    Today, 30th June is asteroid day, to raise awareness of the searches astronomers do to detect and eventually deflect asteroids. This is your chance also to actually do something about them by signing the 100x petition (which has been signed by many famous astronomers and astronauts).An asteroid impact is one of the few natural events we can actually prevent with our technology (unlike volcanoes, earthquakes and tsunami). With a few years or decades of warning, we can deflect them rather easily. But to find them in good time, first we need to detect them. read more

    If you suffer from chronic low back pain and need spinal fusion surgery, there is good news for your golf game. A new study shows an overwhelming majority of spinal fusion patients returned to play golf as well, if not better, than before surgery. During spinal fusion surgery, two vertebrae are joined together using a bone graft taken from another part of the body. In traditional open surgery, a large incision is made to cut through muscles surrounding the spine. Minimally invasive surgery allows for a smaller incision with less muscle damage, resulting in less blood loss, shorter hospital…

They discovered that by using the neural networks “in reverse” they could elicit visualisations of the representations that the networks had developed over training. These pictures are freaky because they look sort of like the things the network had been trained to classify, but without the coherence of real-world scenes. In fact, the…

    by Friedrich W. Johenning, Anne-Kathrin Theis, Ulrike Pannasch, Martin Rückl, Sten Rüdiger, Dietmar Schmitz A key feature of signalling in dendritic spines is the synapse-specific transduction of short electrical signals into biochemical responses. Ca2+ is a major upstream effector in this transduction cascade, serving both as a depolarising electrical charge carrier at the membrane and an intracellular second messenger. Upon action potential firing, the majority of spines are subject to global back-propagating action potential (bAP) Ca2+ transients. These transients translate neuronal…

It has previously been hypothesized that this regression results from an intrinsic volatility in these memories, resulting in an inevitable decay in the absence of ongoing error signals. However, a recently-proposed alternative posits that even recently-acquired motor memories are intrinsically stable, decaying only if a change in context is detected. This new theory, the…

    25 Jun 2015 | 2:00 pm
    by Giulia Palermo, Inga Bauer, Pablo Campomanes, Andrea Cavalli, Andrea Armirotti, Stefania Girotto, Ursula Rothlisberger, Marco De Vivo The fatty acid amide hydrolase (FAAH) regulates the endocannabinoid system cleaving primarily the lipid messenger anandamide. FAAH has been well characterized over the years and, importantly, it represents a promising drug target to treat several diseases, including inflammatory-related diseases and cancer. But its enzymatic mechanism for lipid selection to specifically hydrolyze anandamide, rather than similar bioactive lipids, remains elusive. Here, we…
  • A Computational, Tissue-Realistic Model of Pressure Ulcer Formation in Individuals with Spinal Cord Injury

    Cordelia Ziraldo et al.
    25 Jun 2015 | 2:00 pm
    by Cordelia Ziraldo, Alexey Solovyev, Ana Allegretti, Shilpa Krishnan, M. Kristi Henzel, Gwendolyn A. Sowa, David Brienza, Gary An, Qi Mi, Yoram Vodovotz People with spinal cord injury (SCI) are predisposed to pressure ulcers (PU). PU remain a significant burden in cost of care and quality of life despite improved mechanistic understanding and advanced interventions. An agent-based model (ABM) of ischemia/reperfusion-induced inflammation and PU (the PUABM) was created, calibrated to serial images of post-SCI PU, and used to investigate potential treatments in silico. Tissue-level features of…
  • Time-Course Gene Set Analysis for Longitudinal Gene Expression Data

    Boris P. Hejblum et al.
    25 Jun 2015 | 2:00 pm
    by Boris P. Hejblum, Jason Skinner, Rodolphe Thiébaut Gene set analysis methods, which consider predefined groups of genes in the analysis of genomic data, have been successfully applied for analyzing gene expression data in cross-sectional studies. The time-course gene set analysis (TcGSA) introduced here is an extension of gene set analysis to longitudinal data. The proposed method relies on random effects modeling with maximum likelihood estimates. It allows to use all available repeated measurements while dealing with unbalanced data due to missing at random (MAR) measurements. TcGSA is…

  • Drosophila Lipophorin Receptors Recruit the Lipoprotein LTP to the Plasma Membrane to Mediate Lipid Uptake

    Míriam Rodríguez-Vázquez et al.
    29 Jun 2015 | 2:00 pm
    by Míriam Rodríguez-Vázquez, David Vaquero, Esmeralda Parra-Peralbo, John E. Mejía-Morales, Joaquim Culi Lipophorin, the main Drosophila lipoprotein, circulates in the hemolymph transporting lipids between organs following routes that must adapt to changing physiological requirements. Lipophorin receptors expressed in developmentally dynamic patterns in tissues such as imaginal discs, oenocytes and ovaries control the timing and tissular distribution of lipid uptake. Using an affinity purification strategy, we identified a novel ligand for the lipophorin receptors, the circulating…
  • Separable Crossover-Promoting and Crossover-Constraining Aspects of Zip1 Activity during Budding Yeast Meiosis

    Karen Voelkel-Meiman et al.
    26 Jun 2015 | 2:00 pm
    by Karen Voelkel-Meiman, Cassandra Johnston, Yashna Thappeta, Vijayalakshmi V. Subramanian, Andreas Hochwagen, Amy J. MacQueen Accurate chromosome segregation during meiosis relies on the presence of crossover events distributed among all chromosomes. MutSγ and MutLγ homologs (Msh4/5 and Mlh1/3) facilitate the formation of a prominent group of meiotic crossovers that mature within the context of an elaborate chromosomal structure called the synaptonemal complex (SC). SC proteins are required for intermediate steps in the formation of MutSγ-MutLγ crossovers, but whether the assembled SC…
  • Genetic Changes to a Transcriptional Silencer Element Confers Phenotypic Diversity within and between Drosophila Species

    Winslow C. Johnson et al.
    26 Jun 2015 | 2:00 pm
    by Winslow C. Johnson, Alison J. Ordway, Masayoshi Watada, Jonathan N. Pruitt, Thomas M. Williams, Mark Rebeiz The modification of transcriptional regulation has become increasingly appreciated as a major contributor to morphological evolution. However, the role of negative-acting control elements (e.g. silencers) in generating morphological diversity has been generally overlooked relative to positive-acting “enhancer” elements. The highly variable body coloration patterns among Drosophilid insects represents a powerful model system in which the molecular alterations that underlie…

    by Janna L. Fierst, John H. Willis, Cristel G. Thomas, Wei Wang, Rose M. Reynolds, Timothy E. Ahearne, Asher D. Cutter, Patrick C. Phillips The self-fertile nematode worms Caenorhabditis elegans, C. briggsae, and C. tropicalis evolved independently from outcrossing male-female ancestors and have genomes 20-40% smaller than closely related outcrossing relatives. This pattern of smaller genomes for selfing species and larger genomes for closely related outcrossing species is also seen in plants. We use comparative genomics, including the first high quality genome assembly for an outcrossing…

    by Wilfried Posch, Marion Steger, Ulla Knackmuss, Michael Blatzer, Hanna-Mari Baldauf, Wolfgang Doppler, Tommy E. White, Paul Hörtnagl, Felipe Diaz-Griffero, Cornelia Lass-Flörl, Hubert Hackl, Arnaud Moris, Oliver T. Keppler, Doris Wilflingseder DCs express intrinsic cellular defense mechanisms to specifically inhibit HIV-1 replication. Thus, DCs are productively infected only at very low levels with HIV-1, and this non-permissiveness of DCs is suggested to go along with viral evasion. We now illustrate that complement-opsonized HIV-1 (HIV-C) efficiently bypasses SAMHD1 restriction and…

    by Greta A. Van Slyke, Jamie J. Arnold, Alex J. Lugo, Sara B. Griesemer, Ibrahim M. Moustafa, Laura D. Kramer, Craig E. Cameron, Alexander T. Ciota High rates of error-prone replication result in the rapid accumulation of genetic diversity of RNA viruses. Recent studies suggest that mutation rates are selected for optimal viral fitness and that modest variations in replicase fidelity may be associated with viral attenuation. Arthropod-borne viruses (arboviruses) are unique in their requirement for host cycling and may necessitate substantial genetic and phenotypic plasticity. In order to more…
  • Human Immunodeficiency Virus Type 1 Nef Inhibits Autophagy through Transcription Factor EB Sequestration

    Grant R. Campbell et al.
    26 Jun 2015 | 2:00 pm
    by Grant R. Campbell, Pratima Rawat, Rachel S. Bruckman, Stephen A. Spector HIV Nef acts as an anti-autophagic maturation factor through interaction with beclin-1 (BECN1). We report that exposure of macrophages to infectious or non-infectious purified HIV induces toll-like receptor 8 (TLR8) and BECN1 dependent dephosphorylation and nuclear translocation of TFEB and that this correlates with an increase in autophagy markers. RNA interference for ATG13, TFEB, TLR8, or BECN1 inhibits this HIV-induced autophagy. However, once HIV establishes a productive infection, TFEB phosphorylation and…

    by Sergio Agnoli, Andrea Pittarello, Dorina Hysenbelli, Enrico Rubaltelli Two studies investigated the effect of trait Emotional Intelligence (trait EI) on people’s motivation to help. In Study 1, we developed a new computer-based paradigm that tested participants’ motivation to help by measuring their performance on a task in which they could gain a hypothetical amount of money to help children in need. Crucially, we manipulated participants’ perceived efficacy by informing them that they had been either able to save the children (positive feedback) or unable to save the children…
  • The Nucleotide-Free State of the Multidrug Resistance ABC Transporter LmrA: Sulfhydryl Cross-Linking Supports a Constant Contact, Head-to-Tail Configuration of the Nucleotide-Binding Domains

    Peter M. Jones et al.
    29 Jun 2015 | 2:00 pm
    by Peter M. Jones, Anthony M. George ABC transporters are integral membrane pumps that are responsible for the import or export of a diverse range of molecules across cell membranes. ABC transporters have been implicated in many phenomena of medical importance, including cystic fibrosis and multidrug resistance in humans. The molecular architecture of ABC transporters comprises two transmembrane domains and two ATP-binding cassettes, or nucleotide-binding domains (NBDs), which are highly conserved and contain motifs that are crucial to ATP binding and hydrolysis. Despite the improved clarity…

Then, third-party applications came along and made things more productive than generating an html table on a blog. They hooked into Twitter’s API and such, until Twitter blocked them some time after creating its own Twitter lists section. Now, my…

  • How climate drives bird migration

    14 May 2015 | 8:49 am
    How climate drives bird migration Pine siskins, a species of seed-eating boreal bird, will spend some winters in the pine, spruce and fir forests of Canada, and then arrive at bird feeders much farther south during others. Ornithologists suspected the irregular migrations tracked oscillating climate patterns, but a direct link was elusive, until now. Pine Siskin photo by PutneyPics Why do certain birds suddenly leave their winter territory -- sometimes in the middle of winter? The more familiar, "seasonal" migration is triggered by changes in day length, and birds tend to fly south in winter.

    Scientists on Monday announced the discovery in Yunnan Province of beautifully preserved fossils of one of the stranger animals ever to call Earth home. The creature, Collinsium ciliosum, lived during the Cambrian Period, a time of remarkable evolutionary experimentation when many unusual animals appeared and vanished. "Collinsium is definitely an odd-looking animal, and if one were to bump into one of these during a snorkeling or diving trip nowadays it would be quite shocking," said University of Cambridge paleobiologist Javier Ortega-Hernández, whose research appears in the…

    The finding — a revised estimate of numbers first presented at a scientific meeting in 2013 — represents a tally of deaths from diabetes, heart disease and cancer that scientists say can be directly attributed to the consumption of sweetened sodas, fruit drinks, sports/energy drinks and iced teas. The numbers imply that sugary drinks can cause as many deaths annually as the flu. "It should be a global priority to substantially reduce or eliminate sugar-sweetened beverages from the diet," said Dr. Dariush Mozaffarian, senior author of the study and dean of the Friedman School of Nutrition…

    Women who experience a traumatic event and develop post-traumatic stress disorder (PTSD) may be at increased risk for heart disease, a new large study suggests. In the study, researchers found that women who had four or more symptoms of PTSD after a traumatic event had a 60 percent increased risk of cardiovascular disease, such as a heart attack or stroke, than women who experienced no trauma, over a 20-year period. Women who had experienced traumatic events but who didn't report experiencing symptoms of PTSD had a 45 percent increased risk of cardiovascular disease, the study found.

    By Richard Cowan WASHINGTON (Reuters) - The failure of a SpaceX rocket over Florida on Sunday should not lead U.S. officials back to Russia to look for a rocket engine that can get military equipment into space, Senate Armed Services Committee Chairman John McCain said on Monday. "This mishap in no way diminishes the urgency of ridding ourselves of the Russian RD-180 rocket engine," McCain said in a statement. The United States has placed tough constraints on new deliveries of the Russian-made engines for U.S. military projects, such as launching satellites into space.

A similar scenario led to the discovery of a new hominid fossil, Australopithecus sediba, near the Malapa cave in South Africa.

    What’s sweet and what’s non-fattening are usually different things, but in 1878 a chemist accidentally discovered a way to have both. Constantin Fahlberg was eating dinner after an exhausting day in the lab when he noticed that his bread tasted sweeter than usual. Tracing the source of the sweetness to his fingers, he returned to the lab to sample every vial and dish until he matched the taste with a beaker of benzoic sulfinide. While Fahlberg’s method was neither advisable nor safe, it did lead to the discovery of an artificial substance 300 times sweeter than sugar. He named it…

    For a planet, this would be like a day at the spa. After years of growing old, a massive planet could, in theory, brighten up with a radiant, youthful glow. Rejuvenated planets, as they are nicknamed, are only hypothetical. But new research from NASA's Spitzer Space Telescope has identified one such candidate, seemingly looking billions of years younger than its actual age. "When planets are young, they still glow with infrared light from their formation," said Michael Jura of UCLA, coauthor of a new paper on the results in the June 10 issue of the Astrophysical Journal Letters. "But as they…
  • Spiral Galaxy Arms --"Incubate Rocky Terrestrial Planets"
    26 Jun 2015 | 6:19 am
    New work from Carnegie's Alan Boss offers a potential solution to a longstanding problem in the prevailing theory of how rocky planets formed in our own Solar System, as well as in others. The snag he's untangling: how dust grains in the matter orbiting a young protostar avoid getting dragged into the star before they accumulate into bodies large enough that their own gravity allows them to rapidly attract enough material to grow into planets. In the early stages of their formation, stars are surrounded by rotating disks of gas and dust. The dust grains in the disk collide and aggregate to…

  • Great Salt Lake May Influence Ozone Levels Nearby

    Daniel Kelly
    25 Jun 2015 | 6:10 am
    Utah’s Great Salt Lake covers an area around 1,700 square miles, making it the largest saltwater lake in the Western Hemisphere. That expansiveness, however, is offset by the relatively shallow depths of the lake that average just 16 feet. Still, scientists say, the size of Great Salt Lake is important to consider when conducting investigations there. One such study currently underway at the lake is looking into the role that the large lake plays in influencing the region’s air quality. Led by researchers at Utah State University, it seeks to quantify the impacts that Great Salt Lake has…

    Scientists from the University of Salford studying in Transylvania’s Lake Stiucii have found that sediment cores can indicate the past political changes that have occurred in an area, according to the BBC. They were joined in the investigation by other researchers from Germany’s Senckenberg Biodiversity and Climate Research Centre. Forty-centimeter sediment cores were taken from the Romanian lake and then divided into half-centimeter sections for analysis. Doing so provided a good resolution for analyzing them, scientists say. “By looking at the rate of sedimentation, you could identify…

    Collecting water samples from lakes can be costly, which is partly why most lakes are only sampled a few times a month. To get around those costs and up the amount of data they collect, scientists have increasingly turned to satellite technology to capture measurements without having to set foot anywhere near the water bodies they’re studying. The abundance of phytoplankton in lakes is one common metric that scientists check when they collect water samples, evidenced by many studies discussing the importance of phytoplankton to lake ecosystems. Because of the measurement’s role in…

It was predatory, it was one of many such weird animals trying to eek out a living in the shallow water off uninhabitable coasts, and considering its lineage, it was likely delicious steamed and with a measured touch of melted butter. We also know that despite being an evolutionary dead end, it’s an important species because it shows us the sheer variety of life able to emerge when animals were a blank…

  • why it’s time to think of aging as an illness

    When someone dies young, we say that this person’s death is tragic, that he or she died before his or her time. When someone dies in advanced age, we say that the deceased has lived a full life and it must have been their time to go as if age alone was the culprit. Both stances are very problematic form a scientific standpoint because, you see, nowhere does our biological makeup have a kill switch. There is not one gene or one process that acts like a ticking clock and once it runs out, we die. In fact there are creatures that seem to be near-immortal in this regard, weird jellyfish and…

However, as we approach Pluto with the fastest spacecraft ever built to study worlds like it, the person in charge of the mission’s science, Alan Stern, insists that it’s a planet and those who defined it otherwise lack a persuasive argument to call it anything else.

    Innovators might be stifled if fees for patents rise too high. European Patent Office European Inventor Award/Flickr, CC BY-NC-NDPatents are instrumental to our current innovation system. They encourage inventors to share their ideas, rather than keeping them secreted away, by offering the inventor exclusive rights to exploit their idea for a limited period. Yet they also cost money to administer, and much of this cost is passed on to the inventor. If that cost is too great, then there’s a risk the patent system will fail to do its duty.

  • Ultracold molecules hint at quantum behaviour

    30 Jun 2015 | 12:00 am
    By achieving the lowest temperature ever recorded, scientists have managed to create ultracold molecules which seem to exist in exotic state.  A research team at the Massachusetts Institute of Technology used a gas mixture of sodium potassium to cool molecules to 500 nanokelvins – just above absolute zero (-273°C) – to create ultracold molecules. “We are very close to the temperature at which quantum mechanics plays a big role in the motion of molecules,” said research leader Professor Martin Zwierlein. In the study, published in the journal Physical Review Letters, the team used…
  • Elusive magnetospheric plasma tubes finally recorded

    26 Jun 2015 | 12:00 am
    After 60 years of research, astronomers have finally observed structures of plasma – one of the four fundamental states of matter – in the magnetosphere. Scientists at the University of Sydney in Australia used a radio telescope and located tubular plasma structures aligned along the Earth’s magnetic field. Research leader, Cleo Loi said: “For over 60 years, scientists believed these structures existed but by imaging them for the first time, we’ve provided visual evidence that they are really there”. In the study, published in Geophysical Research Letters, the team used…

  • Stem cell proteins can regenerate bones

    25 Jun 2015 | 12:00 am
    By using proteins from stem cells, scientists have developed a method to regrow bone tissue. A research team the Gladstone Institutes used proteins produced by stem cells rather than the stem cells themselves to stimulate bone reconstruction. “This proof-of-principle work establishes a novel bone formation therapy that exploits the regenerative potential of stem cells. With this technique, we can produce new tissue that is completely stem cell-derived and that performs similarly with the gold standard in the field,” said Dr Todd McDevitt at Gladstone Institutes. In the study, published in…
  • Martian glass may reveal ancient life

    24 Jun 2015 | 12:00 am
    By using data from Mars, geologists have discovered evidence for the presence of glass which may be key to finding past life. Research at Brown University used satellite data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) and detected deposits of glass on the Red planet – formed by violent impacts – which may preserve evidence of ancient life. PhD student Kevin Cannon at Brown University said: “Glasses are potentially important for preserving biosignatures. Knowing that, we wanted to go look for them on Mars and that’s what we did here.

    Inside every star that shines, there’s a continual tug-of-war of wills—between the outward push of its fusion and the inward pull of its own gravity. No one wins. But once all its hydrogen has burned into helium, the gravitational force, now having no opposition, squeezes the star to its end. A star with a mass less than 1.4 solar masses goes out as a “white dwarf,” a stellar corpse about the size of the Earth, but astonishingly dense. A teaspoon of this remnant would hold the mass of a car. (Solar mass is the unit of expressing the mass of stars, galaxies, and other celestial…

  • Rabbit’s Panoramic Vision

    Anupum Pant
    28 Jun 2015 | 10:35 am
    By Anupum Pant Animals which hunt usually have eyes in the front. Both the eyes have the same field of view. However, since they are separated by some distance, there’s a parallax – information which their brain uses to calculate the three dimensional depth. This 3D vision is a boon for the animals who hunt because it helps them to exactly gauge the prey’s depth. The good 3D vision also comes with its own cons. As both the eyes have the same field of view, the total amount of field they can cover is less. That means they can only see what’s happening in front of…
  • How do Court Reporters Type Incredibly Fast?

    By Anupum Pant I’ve always heard about short-hand, but I never cared to look it up and how it actually works. I had assumed that it must be very similar to what we type and it was a way to make your tyiping faster. Turns out, I was wrong. It’s very different. Whatever happens in the court goes on record. There’s no computer doing the speech to text there. It’s humans. These people are trained to type about 200 words per minute and can manage an accuracy of 98.5%. That’s pretty incredible. But how they do it is a different story. They use a different keyboard…

According the people who’ve tested the taste in the video below, they taste good, like candy. Also, these ants are high in protein, fatty acids and vitamin C. They taste slightly soud because of their Ascorbic acid content. But you have to careful when you eat them because like any other ants these can bite you while you are trying to eat them.

    By Anupum Pant Since you’d have no practical use for them at home, I can’t imagine why you’d want to make carbon nanoparticles at home, but it sure sounds interesting. Grinding a chunk of carbon isn’t the way to go because after a certain point the size of particles stop getting smaller. Buying the nanopowder is definitely expensive. So, what should you do? Well, scientists from University of Illinois have figured out an incredibly simple way to produce them at home. All you’d need for this is a little honey and a microwave.

    By Anupum Pant Flathead screwdrivers are probably the worst kind of screwdrivers, it’s very easy to hurt yourself with them and their design is flawed because they slip very easily. In fact, that is how the square shaped screws intended to be driven by a Robertson screwdriver were invented when Peter L Robertson cut his hand while using a flathead screwdriver.

  • Where Are They?

    Andrew Seel
    27 Jun 2015 | 6:00 am
    Rather than hunting for extraterrestrials, some scientists simply wonder "where are they?" There is a group of scientists who doubt that we will ever make contact with extraterrestrials. They feel that there are just too many unknowns for the Drake equation, a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy, to be useful. Instead of working with such calculations, they simply ask, "Where are they?" Continued below. This question was first asked by the great physicist Enrico Fermi. He reasoned that if there were…

    Have you ever been behind a semi-trailer truck and just haven’t been able to get over to see if there is a car coming the other way? Even if the semi is traveling slowly, you sometimes can’t overtake because of its sheer size. Here in Australia, they can be up to 53.5 meters (175.5 feet), but they can be even longer on private roads in the outback.

    22 Jun 2015 | 7:02 am
    For centuries, artists mixed silver and gold powder with glass to fabricate colorful windows to decorate buildings. The results were impressive, but they didn’t have a scientific reason for how these ingredients together made stained glass. In the early 20th century, the physicist Gustav Mie figured out that the color of a metal nanoparticle is related to its size and the optical properties of the metal and adjacent materials. Researchers have only recently figured out the missing piece of this puzzle. Medieval glass workers would be surprised to find out they were harnessing what…

    In the penultimate episode of season 3, we learned a key piece of information about the Orphan Black clones—the origins of the Castor and Leda Projects lie within a single solitary individual person, Kendall Malone (Alison Steadman). This mysterious woman with a murky legal record is not only a genetic chimera and hence able to... The post Can the Project Castor prions be an STD? appeared first on Science vs Hollywood.

    Times are getting pretty tough for Cosima Neihaus (Tatiana Maslany), the one-woman Clone Club R&D department in the Orphan Black universe. What started out as an irksome cough has progressed into a full-blown autoimmune disorder affecting her respiratory and reproductive systems. In one recent episode (Community of Dreadful Fear and Hate), the extent of Cosima’s... The post Can Kira’s stem cells save Cosima? appeared first on Science vs Hollywood.

    We’ve considered an awful lot about what makes Orphan Black Wikia – Sarah Manning (Tatiana Maslany – IMDb Page), Orphan Black Wiki – Alison Hendrix, (Tatiana Maslany – IMDb Page), and the swelling multitude of clones in the Orphan Black universe so dang diverse. Essentially, each week we’ve asked the science questions on the minds... The post Can clones fall on different parts of the sexuality spectrum? appeared first on Science vs Hollywood.

    So far, this series on the science behind Orphan Black has made a number of conclusions, or should I say clone-clusions? To very briefly summarize: (1) it’s hard to make a synthetic genome; (2) it’s harder to make viable clones, even without first synthesizing their genomes; (3) clones can be wildly different from each other...

    In a recent a blog post (nature vs. nurture), I outlined how it is that we aren’t much closer to understanding what makes each of the clones of Orphan Black totally unique. Though they sure do look alike, Orphan Black Wikia – Sarah Manning (Tatiana Maslany) is a rebel, Orphan Black Wikia – Alison Hendrix...

    For someone suffering from paralysis or limited mobility, visiting with other people is extremely difficult. A team of researchers at the Defitech Foundation Chair in Brain-Machine Interface (CNBI), headed by José del R. Millán, has however been working on a revolutionary brain-machine approach in order to restore a sense of independence to the disabled. The idea is to remotely control a robot from home with one’s thoughts. The research, involving numerous subjects located in different countries, produced excellent results in both human and technical terms. The conclusions are…
