    Want to enhance your memory for facts? Tom Stafford explains a counterintuitive method for retaining information. If I asked you to sit down and remember a list of phone numbers or a series of facts, how would you go about it? There’s a fair chance that you’d be doing it wrong. One of the interesting things about the mind is that even though we all have one, we don’t have perfect insight into how to get the best from it. This is in part because of flaws in our ability to think about our own thinking, which is called metacognition. Studying this self-reflective thought process…

  • ‘High-rise’ chip could shrink supercomputers

    Tom Abate-Stanford
    18 Dec 2014 | 12:39 pm
    At a conference in San Francisco, a Stanford University team revealed how to build high-rise chips that could leapfrog the performance of the single-story logic and memory chips on today’s circuit cards. Those circuit cards are like busy cities in which logic chips compute and memory chips store data. But when the computer gets busy, the wires connecting logic and memory can get jammed. Engineers have created a four-layer prototype high-rise chip. In this representation, the bottom and top layers are logic transistors. Sandwiched between them are two layers of memory. The vertical tubes…
  • How ‘worms’ end up in fool’s gold fossils

    Jeff Sossamon-U. Missouri
    18 Dec 2014 | 11:45 am
    How did ancient soft-body creatures become part of the fossil record? New findings suggest that bacteria involved in the decay of those organisms play an active role in how fossils are formed—often in a matter of just a few tens to hundreds of years. Understanding the relationship between decay and fossilization will inform future study and help researchers interpret fossils in a new way. “The vast majority of the fossil record is composed of bones and shells,” says James Schiffbauer, assistant professor of geological sciences at the University of Missouri. “Fossils of…
  • Can hugs keep us from catching colds?

  • Glacier beds get slippery when ice slides fast

    Mike Krapfl-Iowa State
    18 Dec 2014 | 8:03 am
    As a glacier’s sliding speed increases, the bed beneath the glacier can grow slipperier, laboratory simulations show. Researchers say including this effect in efforts to calculate future increases in glacier speeds could improve predictions of ice volume lost to the oceans and the rate of sea-level rise. Lucas Zoet, a postdoctoral research associate, and Neal Iverson, a professor of geological and atmospheric sciences, at Iowa State University describe the results of their experiments in the Journal of Glaciology. The researchers used a newly constructed sliding simulator device to…

    There is a running joke in America that there are three times as many people in the U.S. claiming to be Irish as there are actual people in Ireland.  Though it's nice to claim to be Irish because of a last name, America is a melting pot. And it is so melted that the genetic ancestry of racial and ethnic groups varies significantly even across different geographic regions in the United States.

    David Bradley
    5 Dec 2014 | 9:22 am
    Depending on whether or not you’re a pessimist or an optimist, either the aphorism “no news is good news” holds true or the maxim “all publicity is good publicity” is more accurate. But, could whether news is good or bad be self-perpetuating, particularly in terms of business and financial news? UK researchers have analysed the impact of the financial crisis that began in 2008 by looking at news output in terms of company chair financial statements for the period 2006 to 2010 for financial companies.

  • Towards a nuanced view of mental distress

    vaughanbell
    16 Dec 2014 | 6:06 am
    In the latest edition of The Psychologist I’m involved in a debate with John Cromby about whether our understanding of mental illness is mired in the past. He thinks it is, I think it isn’t, and we kick off from there. The article is readable online with a free registration but I’ve put the unrestricted version online as a pdf if you want to read it straight away. Much of the debate is over the role of biological explanations in understanding mental distress which I think is widely understood by many. Hopefully, amid the knockabout, the debate gets to clarify some of that.

    by Luis Zaman, Justin R. Meyer, Suhas Devangam, David M. Bryson, Richard E. Lenski, Charles Ofria The evolution of complex organismal traits is obvious as a historical fact, but the underlying causes—including the role of natural selection—are contested. Gould argued that a random walk from a necessarily simple beginning would produce the appearance of increasing complexity over time. Others contend that selection, including coevolutionary arms races, can systematically push organisms toward more complex traits. Methodological challenges have largely precluded experimental tests of these…

    by Chuan Hong, Hanna M. Oksanen, Xiangan Liu, Joanita Jakana, Dennis H. Bamford, Wah Chiu Two crucial steps in the virus life cycle are genome encapsidation to form an infective virion and genome exit to infect the next host cell. In most icosahedral double-stranded (ds) DNA viruses, the viral genome enters and exits the capsid through a unique vertex. Internal membrane-containing viruses possess additional complexity as the genome must be translocated through the viral membrane bilayer. Here, we report the structure of the genome packaging complex with a membrane conduit essential for viral…

    Robert Ietswaart et al.
    18 Dec 2014 | 2:00 pm
    by Robert Ietswaart, Florian Szardenings, Kenn Gerdes, Martin Howard Low copy number plasmids in bacteria require segregation for stable inheritance through cell division. This is often achieved by a parABC locus, comprising an ATPase ParA, DNA-binding protein ParB and a parC region, encoding ParB-binding sites. These minimal components space plasmids equally over the nucleoid, yet the underlying mechanism is not understood. Here we investigate a model where ParA-ATP can dynamically associate to the nucleoid and is hydrolyzed by plasmid-associated ParB, thereby creating nucleoid-bound,…

Temporal coherence is the notion that perceived sources emit coherently modulated features that evoke highly-coincident neural response patterns. By clustering the feature channels with coincident responses and reconstructing their input, one may segregate the underlying source from the simultaneously interfering signals that are uncorrelated with it.

One key result is the existence of a symmetry-breaking bifurcation at a critical system size, where there is a switch from evenly distributed exploitation of all options to a focussed exploitation of just one. Here we present a decision-making model in which symmetry-breaking is followed by a symmetry restoring bifurcation, whereby very large…
  • Immuno-epidemiological Modeling of HIV-1 Predicts High Heritability of the Set-Point Virus Load, while Selection for CTL Escape Dominates Virulence Evolution

    Christiaan H. van Dorp et al.
    18 Dec 2014 | 2:00 pm
    by Christiaan H. van Dorp, Michiel van Boven, Rob J. de Boer It has been suggested that HIV-1 has evolved its set-point virus load to be optimized for transmission. Previous epidemiological models and studies into the heritability of set-point virus load confirm that this mode of adaptation within the human population is feasible. However, during the many cycles of replication between infection of a host and transmission to the next host, HIV-1 is under selection for escape from immune responses, and not transmission. Here we investigate with computational and mathematical models how these…
  • Metadynamics Simulations Reveal a Na+ Independent Exiting Path of Galactose for the Inward-Facing Conformation of vSGLT

    Ina Bisha et al.
    18 Dec 2014 | 2:00 pm
    by Ina Bisha, Alex Rodriguez, Alessandro Laio, Alessandra Magistrato Sodium-Galactose Transporter (SGLT) is a secondary active symporter which accumulates sugars into cells by using the electrochemical gradient of Na across the membrane. Previous computational studies provided insights into the release process of the two ligands (galactose and sodium ion) into the cytoplasm from the inward-facing conformation of Vibrio parahaemolyticus sodium/galactose transporter (vSGLT). Several aspects of the transport mechanism of this symporter remain to be clarified: (i) a detailed kinetic and…

    by Bastien Gerby, Cedric S. Tremblay, Mathieu Tremblay, Shanti Rojas-Sutterlin, Sabine Herblot, Josée Hébert, Guy Sauvageau, Sébastien Lemieux, Eric Lécuyer, Diogo F. T. Veiga, Trang Hoang The molecular determinants that render specific populations of normal cells susceptible to oncogenic reprogramming into self-renewing cancer stem cells are poorly understood. Here, we exploit T-cell acute lymphoblastic leukemia (T-ALL) as a model to define the critical initiating events in this disease. First, thymocytes that are reprogrammed by the SCL and LMO1 oncogenic transcription factors into…
  • Epistatic Adaptive Evolution of Human Color Vision

    Shozo Yokoyama et al.
    18 Dec 2014 | 2:00 pm
    by Shozo Yokoyama, Jinyi Xing, Yang Liu, Davide Faggionato, Ahmet Altun, William T. Starmer Establishing genotype-phenotype relationship is the key to understand the molecular mechanism of phenotypic adaptation. This initial step may be untangled by analyzing appropriate ancestral molecules, but it is a daunting task to recapitulate the evolution of non-additive (epistatic) interactions of amino acids and function of a protein separately. To adapt to the ultraviolet (UV)-free retinal environment, the short wavelength-sensitive (SWS1) visual pigment in human (human S1) switched from detecting…

  • Genetic Basis of Haloperidol Resistance in Saccharomyces cerevisiae Is Complex and Dose Dependent

    Xin Wang et al.
    18 Dec 2014 | 2:00 pm
    by Xin Wang, Leonid Kruglyak The genetic basis of most heritable traits is complex. Inhibitory compounds and their effects in model organisms have been used in many studies to gain insights into the genetic architecture underlying quantitative traits. However, the differential effect of compound concentration has not been studied in detail. In this study, we used a large segregant panel from a cross between two genetically divergent yeast strains, BY4724 (a laboratory strain) and RM11_1a (a vineyard strain), to study the genetic basis of variation in response to different doses of a drug.

    by John M. Smith, Michelle E. Leslie, Samuel J. Robinson, David A. Korasick, Tong Zhang, Steven K. Backues, Peter V. Cornish, Abraham J. Koo, Sebastian Y. Bednarek, Antje Heese Vesicular trafficking has emerged as an important means by which eukaryotes modulate responses to microbial pathogens, likely by contributing to the correct localization and levels of host components necessary for effective immunity. However, considering the complexity of membrane trafficking in plants, relatively few vesicular trafficking components with functions in plant immunity are known. Here we demonstrate that…
  • Extreme Divergence of Wolbachia Tropism for the Stem-Cell-Niche in the Drosophila Testis

    Michelle E. Toomey et al.
    18 Dec 2014 | 2:00 pm
    by Michelle E. Toomey, Horacio M. Frydman Microbial tropism, the infection of specific cells and tissues by a microorganism, is a fundamental aspect of host-microbe interactions. The intracellular bacteria Wolbachia have a peculiar tropism for the stem cell niches in the Drosophila ovary, the microenvironments that support the cells producing the eggs. The molecular underpinnings of Wolbachia stem cell niche tropism are unknown. We have previously shown that the patterns of tropism in the ovary show a high degree of conservation across the Wolbachia lineage, with closely related Wolbachia…
  • HSV-2-Driven Increase in the Expression of α4β7 Correlates with Increased Susceptibility to Vaginal SHIVSF162P3 Infection

    Diana Goode et al.

    by Diana Goode, Rosaline Truong, Guillermo Villegas, Giulia Calenda, Natalia Guerra-Perez, Michael Piatak, Jeffrey D. Lifson, James Blanchard, Agegnehu Gettie, Melissa Robbiani, Elena Martinelli The availability of highly susceptible HIV target cells that can rapidly reach the mucosal lymphoid tissues may increase the chances of an otherwise rare transmission event to occur. Expression of α4β7 is required for trafficking of immune cells to gut inductive sites where HIV can expand and it is expressed at high level on cells particularly susceptible to HIV infection. We hypothesized that HSV-2…

    by Fiona M. Sansom, Julie E. Ralton, M. Fleur Sernee, Alice M. Cohen, David J. Hooker, Elizabeth L. Hartland, Thomas Naderer, Malcolm J. McConville Parasitic protozoa, such as Leishmania species, are thought to express a number of surface and secreted nucleoside triphosphate diphosphohydrolases (NTPDases) which hydrolyze a broad range of nucleoside tri- and diphosphates. However, the functional significance of NTPDases in parasite virulence is poorly defined. The Leishmania major genome was found to contain two putative NTPDases, termed LmNTPDase1 and 2, with predicted NTPDase catalytic…

    When a baseball player is hitting well, commentators will sometimes say that it looks like he's hitting with a bigger bat out there. The ACME Catalog, a creative technology studio, took the phrase to a more literal sense. They used baseball bats to represent on-base plus slugging (OPS), "the ability of a player both to get on base and to hit for power," for standout players during the regular season versus the World Series. The standard baseball bat is about two and a half inches in diameter, which was used to represent the league average OPS. With a quick calculation, find how much greater a…

  • Songbirds fly coop long before tornadoes arrive in Tennessee

    18 Dec 2014 | 9:13 am
    By Will Dunham WASHINGTON (Reuters) - You might want to be careful about who you call a birdbrain. Some of our feathered friends exhibit powers of perception that put humans to shame. Scientists said on Thursday that little songbirds known as golden-winged warblers fled their nesting grounds in Tennessee up to two days before the arrival of a fierce storm system that unleashed 84 tornadoes in southern U.S. states in April. The researchers said the birds were apparently alerted to the danger by sounds at frequencies below the range of human hearing. ...
  • NASA's Kepler Spacecraft Finds 1st Alien Planet of New Mission

    18 Dec 2014 | 8:58 am
    NASA's Kepler space telescope is discovering alien planets again. "Like a phoenix rising from the ashes, Kepler has been reborn and is continuing to make discoveries," study lead author Andrew Vanderburg, of the Harvard-Smithsonian Center for Astrophysics (CfA), said in a statement. The spacecraft has been incredibly successful to date, finding nearly 1,000 confirmed planets — more than half of all known alien worlds — along with about 3,200 other "candidates," the vast majority of which should turn out to be the real deal. The spacecraft finds planets by the…
  • Strange Fossil Shows How Life Responded After Mass Extinction

    18 Dec 2014 | 7:11 am
    A strange marine reptile from the age of dinosaurs that was recently unearthed in China may shed light on how life recovered after the greatest mass extinction in Earth's history, researchers say. The creatures were odd-looking predators that grew to about 6 feet (2 meters) in size, and have so far only been found in the province of Hubei in central China. "Hupehsuchia is a group of bizarre marine reptiles unlike anything living today," said study co-author Ryosuke Motani, a vertebrate paleontologist at the University of California, Davis.
  • Ancient Farmhouse Found in Israel Reveals Agricultural Secrets

The house, which measures 98 by 131 feet (30 by 40 meters), is "extraordinarily well preserved," Amit Shadman, excavation director on behalf of the Israel Antiquities Authority, said in a statement. The farmhouse dates back to the time of the Assyrian conquest, when the Assyrians conquered Northern Israel, the…
  • Parents: How to Help a Shy Kid

    18 Dec 2014 | 7:08 am
    Shy babies and toddlers are at greater risk of developing anxiety later in life, compared with outgoing kids. In fact, shyness and withdrawal from new situations is linked to later anxiety only in babies and toddlers without a secure attachment to their caregivers, according to new research published today (Dec. 18) in the journal Child Development. A secure attachment is a warm, nurturing relationship in which kids feel confident to explore when their mom or dad is around, and also feel comfortable seeking reassurance from them when upset. "For those [kids] that do show inhibition across…

  • qPCR: RNA quality and why it matters

    Karen O'Hanlon Cohrt
    18 Dec 2014 | 4:00 am
    Gene expression analysis plays a pivotal role in a wide range of studies, including biomedical analysis and diagnostics. Of all the methods available for gene expression analysis, quantitative real-time PCR (qRT-PCR) is the most rapid, sensitive, and accurate to measure mRNA, and its use in clinical diagnostics is rising steadily. RNA quality entails both purity and integrity. Both play a critical role in the accuracy, reproducibility and relevance of downstream analyses, and isolation of high quality RNA is therefore an essential prerequisite for the techniques used in gene expression and…

  • Saying goodbye to 454: how to choose your next NGS platform

    Kristin Harper
    16 Dec 2014 | 11:30 pm
    The Rise and Fall of the 454 Sequencer The GS20 454 sequencer, released in 2005, was the first next-generation DNA sequencer to hit the market, and its feats quickly dazzled the scientific community. As new sequencing platforms proliferated, however, many researchers opted for less expensive options and 454 market share fell. About a year ago, Roche announced that it was closing its 454 facility in Branford, Connecticut and phasing out the sequencers by mid-2016. Many researchers are discovering that their core labs are already retiring 454 sequencers, while other scientists have decided on…
  • PIER, HIER and Mannich: Antigen Retrieval in Immunohistochemistry

    Martin Wilson
    16 Dec 2014 | 10:04 am
    When you fix your tissue samples with paraformaldehyde (PFA) the proteins in your sample become covalently cross-linked. This is good to preserve the ‘architecture’ of your tissue sample. However, this cross-linking can become a problem when you carry out immunohistochemistry (IHC). Cross-linking can ‘mask’ or hide your antigens-of-interest and make them ‘invisible’ to your IHC detection antibody. This is where ‘antigen retrieval’ or ‘unmasking’ is essential to know. For over 20 years I worked in the field of contraceptive vaccines examining sperm/egg recognition. Much of…

    17 Dec 2014 | 8:24 am
    Thirty years ago an HIV diagnosis was a death sentence. Today, sophisticated drug cocktails known as highly active antiretroviral therapy, or HAART, have dramatically changed the fates of people with the disease.  Yet in many ways we’re treading water: each year the U.S. sees around 50,000 new HIV cases, and estimates show that 20-25% of these people don’t know they’re infected. And, while the drugs are effective, many people throughout the world can’t afford them. So should we consider our response to HIV a complete success story? This episode of Distillations tries to find the…

    Penn State’s attempt to auction off 112 of its 540 active patents was disappointing. Only two bids were publically placed, one purchasing a license for a “metal-electroactive ceramic composite transducer” for $5,000. Penn State is the first institution in the country to sell patent licenses through an online auction modeled after eBay. In fact this was their second attempt. In April 2014 the University sold only 2 of 73 engineering patents. The winning bidder received an exclusive license to commercialize them. Penn State stopped paying the maintenance fees for unsold patents after the…

    Athletes want to win—sometimes taking extreme measures to push through the pain and perform at their best. But when has an athlete gone too far? When it gives the athlete an unfair advantage—and threatens his or her health. Painless Play Abusing drugs to overcome pain or inflate athletic abilities is definitely an unfair advantage. This doesn’t include the appropriate use of doctor-prescribed treatments, such as cortisone injections or prescription opioid pain medications. However, using prescription pain medication in a way other than prescribed is not only unfair, it’s dangerous.

    I’ve always been a huge Star Trek fan. When I was a teenager, my hero was Mister Spock—cool, analytical, even-tempered, and smarter than everyone around him. Being raised in his ancient society of the planet Vulcan made him a force to be reckoned with. He was kind and compassionate, but his mind was unswayed by human passions and fears, and he was always in control. When he was alone, he often sat, eyes closed, deep in meditation. Vulcan is a fictional planet, but I later came to learn that there are real people on Earth kind of like Mister Spock, who possess many of his qualities and…

    "Like a phoenix rising from the ashes, Kepler has been reborn and is continuing to make discoveries. Even better, the planet it found is ripe for follow-up studies," says Andrew Vanderburg of the Harvard-Smithsonian Center for Astrophysics (CfA). The report of the Kepler spacecraft's death was greatly exaggerated. Despite a malfunction that ended its primary mission in May 2013, Kepler is still alive and working. The evidence comes from the discovery of a new super-Earth using data collected during Kepler's "second life." NASA's Kepler spacecraft detects planets by looking for transits, when…

    A decade ago, astronomers actually thought that the stars within any cluster should all be about the same age, but that idea fell out of favor when clear evidence of the presence of stars of different ages within a single cluster was discovered, at least for the oldest and most populous clusters in our Milky Way. A close look at the night sky reveals that stars don’t like to be alone; instead, they congregate in clusters, in some cases containing as many as several million stars. Until recently, the oldest of these populous star clusters were considered well understood, with the stars in a…
  • An Alien Water World --"Could It be Habitable?" Asks MIT Team

    dailygalaxy.com
    17 Dec 2014 | 1:43 pm
    Nearly 2,000 planets beyond our solar system have been identified to date. Whether any of these exoplanets are hospitable to life depends on a number of criteria. Among these, scientists have thought, is a planet's obliquity the angle of its axis relative to its orbit around a star.The more extreme the tilt, the less habitable a planet may be or so the thinking has gone. Scientists at MIT have found that even a high-obliquity planet, with a nearly horizontal axis, could potentially support life, so long as the planet were completely covered by an ocean. In fact, even a shallow ocean, about 50…

The team says their findings provide a "global network of sites" with hydrogen-rich waters that can be targeted in the search for deep life over coming years. They also point to the implications for life on Mars. The Red Planet has ancient rocks with hydrogen-producing potential, so could also host microbial life: "If the ancient rocks of Earth…

    The relationship between Earth's plate tectonics and surface water is one of the great mysteries in the geosciences. But a new study supports researchers’ growing suspicion that mantle convection somehow regulates the amount of water in the oceans. It also vastly expands the timeline for Earth’s water cycle. “If all of the Earth’s water is on the surface, that gives us one interpretation of the water cycle, where we can think of water cycling from oceans into the atmosphere and into the groundwater over millions of years,” Wendy Panero, associate professor of earth sciences at Ohio…

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

    22 Aug 2014 | 8:00 am
    When we started BenchFly five years ago, in 2009, our mission was to make research a better career for current and future generations of scientists. Today we continue to work toward this goal using video as the primary means to educate scientists in companies, in universities and now in high schools! In the fall of 2013, we were incredibly fortunate to have met Kentucky teacher Tricia Shelton (thank you, Twitter!) arguably one of the most energetic, passionate, and dedicated teachers out there. In less than 12 months, our collaboration has resulted in a new video-based curriculum, called…
  • Pipetting with Your iPhone?

    16 Jul 2014 | 8:27 am
    “Set timer for ten minutes.” Instead of the kitchen timers the rest of us use, the post-doc sitting behind me regularly uses Siri to time his experiments. As it turns out, it’s actually easier to tell a computer to set a timer for you than to do it yourself, and Siri is quickly becoming our lab’s newest research assistant. With a new iPhone model out each year, it’s not hard to believe that we’ll soon have everything we need on the little 2¼” x 4¾” device we can no longer go anywhere without. But what does that mean for us lab rats? And how can we leverage new technology to…

Apple announced “Continuity” at WWDC, the 2016 US Presidential election is starting to ramp up (wait, WHAT!?), England and Spain were knocked out of the World Cup so fast I didn’t even have time to write a joke about bad refereeing and corrupt FIFA officials, and “Fargo” blazed through ten spectacular episodes on FX.

    18 Dec 2014 | 7:21 am
    Scientists at Ohio State University have ranked the potency of weather changes in driving Great Lakes algal blooms, according to a release from the university. The most influential driver, they’ve found, is wind. Unlike other investigations that have zeroed in on the roles of algae-feeding nitrogen and phosphorus, the study takes a closer look at weather because its factors remain important throughout the year, researchers say, whereas nutrient levels can vary.

  • Higher Arctic Temperatures To Push Greenland’s Glacial Lakes Inland

    Daniel Kelly
    16 Dec 2014 | 7:55 am
    As Arctic temperatures rise, researchers say, supraglacial lakes covering Greenland will double in area, according to Phys.org. The lakes will spread much farther inland than they reach today – about 110 kilometers, or just over 68 miles. Impacts of the supraglacial lakes had long been assumed to be small, but a study led by scientists at the University of Leeds has shown the lakes will have dramatic impacts on the flow of the continent’s ice sheet. With higher temperatures and faster ice melting, changes are expected. Greenland Ice Sheet. (Credit: Flickr User Bernt Rostad via…

Invertebrates make up a large component of the diets of these animals—linking algal and detrital energy sources to higher trophic levels. Therefore, identifying the natural and anthropogenic…
  • Exposed Salts Spell High Albedo For Russia’s Lake Elton

    9 Dec 2014 | 6:53 am
    Russia’s Lake Elton is one of the largest and saltiest inland lakes in Europe. But it is probably better known for its reflective properties, according to a release from NASA’s Earth Observatory. This reflectance is called albedo, essentially the proportion of sunlight an object receives related to the amount of sunlight it reflects back. And Lake Elton has an almost unreal level of albedo, as seen in this satellite photo from August 2014: Lake Elton as seen from space in August 2014.

    There's a balance between service providers' responsiveness and responsibility when it comes to online abuse.

But in Australia, victims often have no real legal remedy for this kind of abuse. This is the key problem of regulating the internet. Often, speech we might consider abusive or offensive isn’t actually illegal. And even when the law technically prohibits something, enforcing it directly against offenders can be difficult. It is…

NASAWhile the Mars Rovers and the Rosetta spacecraft will continue to make headlines in 2015, the stage is set for the solar system’s next great mission – the Pluto-bound New Horizons. Discovered in 1930, it was assumed that Pluto was a planet, with a mass comparable to that of the Earth. This was partially based on its brightness, along with the mistaken assumption that it was perturbing the orbits of Neptune and Uranus. As the decades passed, and our observations of Pluto improved, its…

    If you are away from the bustle of the city these holidays, then try your luck at spotting a faint comet in the northern sky. Comet Lovejoy C/2014 Q2 is the fifth comet to be discovered by Brisbane amateur astronomer Terry Lovejoy. Comets are the only astronomical objects that are automatically named for the person who found them. Lovejoy found the comet last August using an 8-inch telescope. It was about the same distance from the sun as the asteroid belt and was located around 420 million km from Earth. At that distance, the comet’s brightness was measured at 15th magnitude, which is…

    Our reaction to disgusting things may be evolutionarily-derived. Flickr/Rainja, CC BY-NC-NDFeeling queasy? How about deceitful? New research shows feelings of disgust encourage unethical, self-interested behaviours such as lying to get more money. At first look, these findings would suggest that feelings of disgust are to be avoided (such as dealing with that mouldy food container in the work fridge before the holiday break). On deeper reflection, though, the takeaway message isn’t one of “emotions are bad” but instead is one of the significance of our emotional system for helping us…

    Depending on whether or not you’re a pessimist or an optimist, either the aphorism “no news is good news” holds true or the maxim “all publicity is good publicity” is more accurate. But, could whether news is good or bad be self-perpetuating, particularly in terms of business and financial news?

    Is it oversharing to tell you I wasn’t breastfed as an infant? Tough. I don’t feel that being bottlefed formula milk did me any harm. Breastfeeding is natural but it’s not always possible for new mothers and the push from the healthcare workers for breast is best waxes and wanes as any social fashion. There is a lot of guilt poured on mothers who (a) choose to breast feed their infant (b) choose not to breast feed their infant (c) cannot breast feed their infant. Take your pick, there’s guilt from every angle. If it’s physiologically possible it should be every…

      Click on the text boxes above to learn more about the evidence that supports global warming. Scientists around the globe have noticed that over the last 40 years Earth, as a whole, has been warming. This phenomenon, known as global warming, is affecting regional climates differently. For example, some regions may experience warmer summers, while other regions may see winters with heavier snowstorms. A rise in Earth's average temperature isn't always immediately apparent. For example, some places still get snowy winters which might appear to contradict the idea of global warming.

    Click on the red circles above to learn more about the Keeling Curve, which plots CO2 in the Earth’s atmosphere over time. The Keeling Curve is one of the most compelling pieces of scientific evidence that shows that carbon dioxide (CO2) is accumulating in our atmosphere. CO2 is a greenhouse gas. Greenhouse gases trap heat in the atmosphere and help keep the planet warm. More greenhouse gas molecules in the air means more heat is trapped, leading to an overall warming of the planet. CO2 is a molecule made up of one carbon atom and two oxygen atoms, and it moves in and out of the…

    Biology concepts – toxin, botany, cancer chemotherapies, pregnancy, evergreen Noche de Rábanos (Night of the Radishes) is celebrated in Oaxaca, Mexico on December 23. The townspeople carve radishes into shapes, characters or scenes and then they are judged.  It began as a suggestion by a couple of monks to bring people in to the market to buy the produce that the farmers had raised, so it’s a Christmas plant tradition that really has little to do with Christmas.In the middle of Northern hemisphere’s winter we use plants to help celebrate Christmas, but the practice is much older…

Krampus was the spirit who came during Yule to punish children who had misbehaved. Yule celebrations used evergreens (note his headdress) and this has continued in the modern Christmas celebration, but the Krampus became paired with good Saint Nicholas, so they kind of went the other way with that one.Christmas trees are pagan holdovers from when early Christianity adopted December 25th as the date of the holiday.

    LaboratoryNews
    18 Dec 2014 | 12:00 am
    Researchers have shed new light on a long standing conundrum in condensed-matter physics by combining electron microscopy and laser spectroscopy in novel ways. Vanadium dioxide has intrigued the scientific community since the late 1950s; it acts as a semiconductor at low temperatures, but transforms into a highly conductive metal at around 60°C, meaning a range of potential applications from high-speed optical switches to heat sensitive smart coatings. Researchers at McGill University have developed instrumentation uniting electron microscopy and laser spectroscopy which has enabled them to…
  • X-ray absorption reveals water structure mystery

    LaboratoryNews
    12 Dec 2014 | 12:00 am
    A new twist on x-ray absorption spectroscopy has allowed American scientists to reveal the molecular structure of water at gold electrodes. When a solid is immersed in liquid, the liquid immediately next to its surface differs from the bulk of the liquid – when the solid surface is charged it can drive further changes, but elucidating the molecular structure at the interface has proved difficult. Now, scientists at the Lawrence Berkeley National Laboratory have observed this molecular structure at a gold surface under different conditions. The team used a 100nm x-ray transparent window with…

Its caterpillars can only eat wild lupines — a flower that’s become less abundant in the wild because of development and habitat fragmentation. As a result, the Karner was named an endangered species in 1992. But Karner blues are getting help from an unlikely source: gun sales.The Nature Conservancy has a project in the works near Saratoga, New York, that will preserve an area that’s already home to these lupines and…

It was long presumed that the planet wasn’t born with it, but that it appeared some 700 million years later—likely from comets. But data sent back by Rosetta from comet 67/P refutes that theory, reports The New York Times. The water on it—which exists in the form of ice and vapor—is different from terrestrial water.

It’s hard to believe that no one has topped it after that. Not even after immense technological advancement of the twenty first century has man moved a rock larger than that one. In 1768, in order to build a huge statue for Peter the great, a three million pound stone was required to be moved into St. Petersburg. This would later serve as a platform to put up the equestrian statue on it. But before everything, a rock that huge needed to…

Still, there are a few reliable estimates which say that about 150,000 to 170,000 tonnes of gold has been mined till date. The 170,000 tonnes figure is the most reliable estimate, which would mean that the amount of gold ever mined can fit in a not-so-massive cube with each side measuring 21 meters. However, some estimates take the figure up to 2.5 million tonnes. That said, how much more is yet to be mined then? A good estimate is that about 52000 tonnes of gold is…

An engine like any other heat engine which converts heat into mechanical energy. For a Stirling engine to work, all you need is a relatively tiny amount of temperature difference on its two sides. The lower part of the engine setup can be heated using the heat from a coffee cup, and the upper part is exposed to the room temperate. As the lower part of it gets heated, the air expands, pushes the piston. Next, it cools, the air contracts and the piston comes back. This…

  • OMNI Magazine December 1990: Special UFO Edition

    Andrew Seel
    18 Dec 2014 | 10:00 am
    The December 1990 Issue of OMNI Magazine investigates the search for extraterrestrial intelligence. If extraterrestrial intelligence is out there somewhere, OMNI magazine wanted to be the first to know in the December 1990 issue. The first messages from space will probably arrive in the form of radio waves, or an invading fleet of flying saucers hungry for a habitable world. Jill Tarter was a radio astronomer devoted to the search for life in the cosmos. The logic behind listening for radio signals works as follows. If radio technology is the entrance exam to be a galactic explorer, then…

    Nearly every CGI film contains polymer from the special effects company Smooth-On. Films are not just CGI and green screens. There are numerous artists who work diligently to create mind-boggling and realistic effects that engage the senses. Smooth-On is one of the most famous companies creating polymer products in the special effects industry. Almost every film that has employed special effects in the last two decades can trace its roots back to Smooth-On. From Star Wars to Alien, there is a touch of their polymer in almost every CGI film. They have not just pervaded the special effects…
  • The Dvorak Keyboard Says People Are Typing Wrong

    People are exerting too much effort to type according to proponents of the Dvorak keyboard. According to proponents of the Dvorak keyboard people are wasting time with the standard QWERTY keyboard. The rearranged keys on the Dvorak keyboard are said to use less finger motion, increase typing rate, and reduce errors when compared to standard keyboards. Research has shown it improves typing efficiency up to 50 percent. Is the cult-following keyboard really a shortcut to higher productivity?

    Soviet artist Andrei Sokolov painted the stars red with the first art exhibition to be featured in space. After the launch of the Earth's first artificial satellite in 1957 Andrei Sokolov painted the stars red by dedicating all of his creative efforts to space exploration. Russia's foremost space artist had his artwork carried by cosmonauts Romanenko and Grechko into orbit in March 1971 aboard Soyuz 11. The paintings were gouache on nonfolding cardboard, measured 47 centimeters by 36 centimeters, and weighed 130 grams each. They were transferred to the orbiting space laboratory Salyut, to…

    Walker Stalker Con may become a huge convention to rival Comic Con in the future. Walker Stalker Con was an enormous success but the convention could have been called Walking Dead Con and it would have been equally gigantic. There are a plethora of zombie television shows, films, and video-games that were not represented. While some classic films were highlighted at the convention, such as Night of the Living Dead, other contemporary zombie television shows were nowhere to be seen like the empty streets of Atlanta after the apocalypse.

  • Kepler proves it can still find planets

    18 Dec 2014 | 9:27 am
    To paraphrase Mark Twain, the report of the Kepler spacecraft's death was greatly exaggerated. Despite a malfunction that ended its primary mission in May 2013, Kepler is still alive and working. The evidence comes from the discovery of a new super-Earth using data collected during Kepler's "second life." "Like a phoenix rising from the ashes, Kepler has been reborn and is continuing to make discoveries. Even better, the planet it found is ripe for follow-up studies," says lead author Andrew Vanderburg of the Harvard-Smithsonian Center for Astrophysics (CfA). Subject: …

  • How Astronaut Poop Can Power a Rocket’s Return Flight to Earth

    Des Ford
    18 Dec 2014 | 8:55 am
    NASA enlisted the aid of researchers at the University of Florida to reduce the weight of spacecraft leaving Earth. They came up with a way to make rocket fuel from human waste (especially poop). Enough to power the return flight, saving on carting all that fuel into space. An added bonus was not having to carry all that waste back to Earth where it’s usually burned up during re-entry. Researchers found an anerobic digester process that could produce 290 liters of methane per crew per day, all from human waste. This must be useful here on Earth.

    This is footage from one of four reels of film recently obtained in Russia of what is possibly a small crashed UFO being filmed and inspected by the Russian military at the behest of the KGB, which means the event occurred before the collapse of the Soviet Union in 1991. Judging by the number of Russian military present, including the KGB, there was a great deal of interest in this object. There were two cameramen present, one filming with a handheld camera from a Russian military truck, and the other filming with a camera on a tripod on the ground.

This video is very interesting, and points out many “coincidences.” The premise is as follows. There are many references in the film that seem to presage the 9/11 Twin Tower attacks. The numbers 9/11 appear many times throughout Back to the Future, so many times that you start to question whether they are all really just a coincidence. There are many references to the Twin Towers themselves, some indirect and some direct. One is the terrorist attack at the Twin Pines Mall…

If species were immutable, meaning they never changed, then how was it that breeders were able to change the forms of dogs or pigeons? What if something similar occurred in nature? According to William Paley nature required a designer. Charles began to think that Nature was the designer. A blind designer with no goal in mind at all.
