    Eating probiotics regularly may modestly improve your blood pressure, according to a new review of none studies examining blood pressure and probiotic consumption in 543 adults with normal and elevated blood pressure. Probiotics are live microorganisms naturally occurring bacteria in the gut thought to have beneficial effects; they have recently been a nutrition trend and common sources are yogurt or dietary supplements.  read more

    The sun has gone quiet. Almost too quiet. A few weeks ago it was teeming with sunspots, as you would expect since we are supposed to be in the middle of solar maximum-the time in the sun's 11-year cycle when it is the most active.

  • Loss of sleep after divorce can spike blood pressure

    Alexis Blue-U. Arizona
    21 Jul 2014 | 12:08 pm
    Divorce-related sleep problems may be partly to blame for significant health problems, including high blood pressure and even early death, research suggests. “In the initial few months after a separation, sleep problems are probably pretty normal, and this is an adjustment process that people can typically cope with well,” says David Sbarra, associate professor of psychology at University of Arizona. “But sleep problems that persist for an extended period may mean something different. It may mean that people are potentially becoming depressed, that they’re struggling…
  • Great Barrier Reef may face a deadly summer

    21 Jul 2014 | 11:45 am
    Researchers fear this summer will bring an increase in coral death to the Great Barrier Reef, as the reef is at greater risk than ever from severe weather events. The prediction is based on research into the history of coral death on the reef. The results from that research will help reef managers across the globe reconstruct the history of their reefs and improve management practices.

  • Baby’s brain ‘rehearses’ before first words

    Molly McElroy-UW
    21 Jul 2014 | 7:24 am
    New research shows that speech sounds stimulate areas of an infant’s brain that coordinate and plan for the physical movements needed for speech. Infants can tell the difference between sounds of all languages until about 8 months of age when their brains start to focus only on the sounds they hear around them. It’s been unclear how this transition occurs, but social interactions and caregivers’ use of exaggerated “parentese” style of speech seem to help.

    Age-related macular degeneration (AMD) is the most common cause of visual impairment and blindness in industrialized countries but it is questionable whether it can continue to be defined as a disease in people in their 50s and beyond. Investigations to determine the incidence of age-related macular degeneration undertaken as part of the Gutenberg Health Study of the University Medical Center of Johannes Gutenberg University Mainz (JGU) have shown that even persons under the age of 50 years may be affected by an early form of the eye disease. Just under 4 percent of the 35 to 44-year-old…
  • Less Random Fitness: A Refined Biological Evolution Model

    News Staff

    Models for the evolution of life are now being developed to try and clarify the long term dynamics of an evolving system of species. Specifically, a recent model proposed by Petri Kärenlampi from the University of Eastern Finland in Joensuu accounts for species interactions with various degrees of symmetry, connectivity, and species abundance. This is an improvement on previous, simpler models, which apply random fitness levels to species. The findings demonstrate that the resulting replicator ecosystems do not appear to be a self-organized critical model, unlike the so-called Bak Sneppen…

  • When Temperatures Get Cold, Newly-Discovered Process Helps Fruit Flies Cope

    University of Rochester

    Cold-blooded animals cannot regulate their body temperature, so their cells are stressed when facing temperature extremes. Worse still, even at slightly colder temperatures, some biological processes in the cell are slowed down more than others, which should throw the cells' delicate chemical balance out of whack. Yet, those cells manage to keep their biological processes coordinated. Now researchers have found out how they do that.

    This paper hypothesizes that postsynaptic CaMKII (calcium/calmodulin-dependent protein kinase II) receives synaptic input and then interacts with via phosphorylation, suggesting that memories may be encoded in the microtubules in this way. They note that the size and shape of CaMKII appears to be just right to phosphorylate the hexagonal lattices of tubulin proteins in microtubules. The paper also can “demonstrate microtubule-associated protein logic gates, and show how patterns of phosphorylated tubulins in microtubules can control neuronal functions by triggering axonal firings,…

  • Technique named ‘clarity’ makes chunks of dead brain transparent, allowing fluorescent labeling

    Bayle Shanks

    This technique takes a dead brain and permeates it with a transparent hydrogel matrix to keep proteins and nucleic acids in place. Then it removes the lipids. I guess the lipids are all that makes the brain opaque. At this point the brain is transparent but maintains its original structure so you can still label the proteins and nucleic acids. http://www.hhmi.org/news/deisseroth20130410.html

    Today’s edition of Nature has an excellent article on the need to apply cognitive science to understanding how psychological therapies work. Psychological therapies are often called ‘talking treatments’ but this is often a misleading name. Talking is essential, but it’s not where most of the change happens.

In the same way, psychological therapy is only as effective as the experience of putting changes into practice, but we still know relatively…

  • Integration of Signals along Orthogonal Axes of the Vertebrate Neural Tube Controls Progenitor Competence and Increases Cell Diversity

    Noriaki Sasai et al.
    15 Jul 2014 | 2:00 pm
    by Noriaki Sasai, Eva Kutejova, James Briscoe A relatively small number of signals are responsible for the variety and pattern of cell types generated in developing embryos. In part this is achieved by exploiting differences in the concentration or duration of signaling to increase cellular diversity. In addition, however, changes in cellular competence—temporal shifts in the response of cells to a signal—contribute to the array of cell types generated. Here we investigate how these two mechanisms are combined in the vertebrate neural tube to increase the range of cell types and deliver…
  • Palmitoylation of Gephyrin Controls Receptor Clustering and Plasticity of GABAergic Synapses

    Borislav Dejanovic et al.
    15 Jul 2014 | 2:00 pm
    by Borislav Dejanovic, Marcus Semtner, Silvia Ebert, Tobias Lamkemeyer, Franziska Neuser, Bernhard Lüscher, Jochen C. Meier, Guenter Schwarz Postsynaptic scaffolding proteins regulate coordinated neurotransmission by anchoring and clustering receptors and adhesion molecules. Gephyrin is the major instructive molecule at inhibitory synapses, where it clusters glycine as well as major subsets of GABA type A receptors (GABAARs). Here, we identified palmitoylation of gephyrin as an important mechanism of strengthening GABAergic synaptic transmission, which is regulated by GABAAR activity. We…

  • Non-associative Potentiation of Perisomatic Inhibition Alters the Temporal Coding of Neocortical Layer 5 Pyramidal Neurons

    Joana Lourenço et al.
    8 Jul 2014 | 2:00 pm
    by Joana Lourenço, Simone Pacioni, Nelson Rebola, Geeske M. van Woerden, Silvia Marinelli, David DiGregorio, Alberto Bacci In the neocortex, the coexistence of temporally locked excitation and inhibition governs complex network activity underlying cognitive functions, and is believed to be altered in several brain diseases. Here we show that this equilibrium can be unlocked by increased activity of layer 5 pyramidal neurons of the mouse neocortex. Somatic depolarization or short bursts of action potentials of layer 5 pyramidal neurons induced a selective long-term potentiation of GABAergic…

  • Poisson-Like Spiking in Circuits with Probabilistic Synapses

    Rubén Moreno-Bote
    17 Jul 2014 | 2:00 pm
    by Rubén Moreno-Bote Neuronal activity in cortex is variable both spontaneously and during stimulation, and it has the remarkable property that it is Poisson-like over broad ranges of firing rates covering from virtually zero to hundreds of spikes per second. The mechanisms underlying cortical-like spiking variability over such a broad continuum of rates are currently unknown. We show that neuronal networks endowed with probabilistic synaptic transmission, a well-documented source of variability in cortex, robustly generate Poisson-like variability over several orders of magnitude in their…
  • A Multiscale Approach to Modelling Drug Metabolism by Membrane-Bound Cytochrome P450 Enzymes

    Richard Lonsdale et al.
    17 Jul 2014 | 2:00 pm
    by Richard Lonsdale, Sarah L. Rouse, Mark S. P. Sansom, Adrian J. Mulholland Cytochrome P450 enzymes are found in all life forms. P450s play an important role in drug metabolism, and have potential uses as biocatalysts. Human P450s are membrane-bound proteins. However, the interactions between P450s and their membrane environment are not well-understood. To date, all P450 crystal structures have been obtained from engineered proteins, from which the transmembrane helix was absent. A significant number of computational studies have been performed on P450s, but the majority of these have been…
  • P-loop Conformation Governed Crizotinib Resistance in G2032R-Mutated ROS1 Tyrosine Kinase: Clues from Free Energy Landscape

    Huiyong Sun et al.
    17 Jul 2014 | 2:00 pm
    by Huiyong Sun, Youyong Li, Sheng Tian, Junmei Wang, Tingjun Hou Tyrosine kinases are regarded as excellent targets for chemical drug therapy of carcinomas. However, under strong purifying selection, drug resistance usually occurs in the cancer cells within a short term. Many cases of drug resistance have been found to be associated with secondary mutations in drug target, which lead to the attenuated drug-target interactions. For example, recently, an acquired secondary mutation, G2032R, has been detected in the drug target, ROS1 tyrosine kinase, from a crizotinib-resistant patient, who…
  • Characterizing the Impact of Category Uncertainty on Human Auditory Categorization Behavior

    Adam M. Gifford et al.
    17 Jul 2014 | 2:00 pm
    by Adam M. Gifford, Yale E. Cohen, Alan A. Stocker Categorization is an important cognitive process. However, the correct categorization of a stimulus is often challenging because categories can have overlapping boundaries. Whereas perceptual categorization has been extensively studied in vision, the analogous phenomenon in audition has yet to be systematically explored. Here, we test whether and how human subjects learn to use category distributions and prior probabilities, as well as whether subjects employ an optimal decision strategy when making auditory-category decisions. We asked…
  • Rethinking Transcriptional Activation in the Arabidopsis Circadian Clock

    Karl Fogelmark et al.
    17 Jul 2014 | 2:00 pm
    by Karl Fogelmark, Carl Troein Circadian clocks are biological timekeepers that allow living cells to time their activity in anticipation of predictable daily changes in light and other environmental factors. The complexity of the circadian clock in higher plants makes it difficult to understand the role of individual genes or molecular interactions, and mathematical modelling has been useful in guiding clock research in model organisms such as Arabidopsis thaliana. We present a model of the circadian clock in Arabidopsis, based on a large corpus of published time course data. It appears from…

    Anjali G. Hinch et al.
    17 Jul 2014 | 2:00 pm
    by Anjali G. Hinch, Nicolas Altemose, Nudrat Noor, Peter Donnelly, Simon R. Myers The pseudoautosomal region (PAR) is a short region of homology between the mammalian X and Y chromosomes, which has undergone rapid evolution. A crossover in the PAR is essential for the proper disjunction of X and Y chromosomes in male meiosis, and PAR deletion results in male sterility. This leads the human PAR with the obligatory crossover, PAR1, to having an exceptionally high male crossover rate, which is 17-fold higher than the genome-wide average. However, the mechanism by which this obligatory crossover…

    by Angeliki Chalkiadaki, Masaki Igarashi, Armiyaw Sebastian Nasamu, Jovana Knezevic, Leonard Guarente SIRT1 is a metabolic sensor and regulator in various mammalian tissues and functions to counteract metabolic and age-related diseases. Here we generated and analyzed mice that express SIRT1 at high levels specifically in skeletal muscle. We show that SIRT1 transgenic muscle exhibits a fiber shift from fast-to-slow twitch, increased levels of PGC-1α, markers of oxidative metabolism and mitochondrial biogenesis, and decreased expression of the atrophy gene program.

  • Larger Mammalian Body Size Leads to Lower Retroviral Activity

    Aris Katzourakis et al.
    17 Jul 2014 | 2:00 pm
    by Aris Katzourakis, Gkikas Magiorkinis, Aaron G. Lim, Sunetra Gupta, Robert Belshaw, Robert Gifford Retroviruses have been infecting mammals for at least 100 million years, leaving descendants in host genomes known as endogenous retroviruses (ERVs). The abundance of ERVs is partly determined by their mode of replication, but it has also been suggested that host life history traits could enhance or suppress their activity. We show that larger bodied species have lower levels of ERV activity by reconstructing the rate of ERV integration across 38 mammalian species. Body size explains 37% of…

We present ab initio calculations of the energetics of amino acid polymerization via gas phase collisions. The initial hydrogen-bonded di-peptide is sufficiently stable to proceed in many cases via a transition state into a di-peptide with an associated bound water molecule of condensation. The energetics of polymerization are only favorable when the water remains bound. Further polymerization leads to a hydrophobic surface that is…

They penalise sites they consider to be spamming their SERPs with practices that supposedly break their self-created internet rules. They do all this purportedly to make search a better experience for users. The real reason, of course, is so they can sell ad space to companies. Google is fundamentally an advertising company not a search engine.

    Personal data collection keeps getting easier and more efficient. Much of what was manual or clunky a few years ago is now automatic, done via the phone we carry every day anyway. More recently, personal data is finding a way out of the closed networks and applications and on to our own computers and servers. Anand Sharma's personal site is the newest example of what an individual can do with his or her own data. On a whim a few months ago, Sharma downloaded the Moves app, which tracks your location, and was hooked. Then with some design inspiration from Tony Stark, Sharma put a site together…

  • Geologic map of Mars

    Nathan Yau
    18 Jul 2014 | 1:23 am
    The USGS released a more detailed geologic map of Mars, not just renderings based on rough models. The USGS-led mapping effort reveals that the Martian surface is generally older than previously thought. Three times as much surface area dates to the first major geologic time period - the Early Noachian Epoch - than was previously mapped. This timeframe is the earliest part of the Noachian Period, which ranges from about 4.1 to about 3.7 billion years ago, and was characterized by high rates of meteorite impacts, widespread erosion of the Martian surface and the likely presence of abundant…
  • Spiky betting odds during LeBron James decision

    Nathan Yau
    17 Jul 2014 | 3:44 am
    LeBron James decided to head back to Cleveland, so naturally the odds that they win the championship went up. Todd Schneider charted the betting odds as the announcement happened to see how much they went up. Of course that 10% already had built in some likelihood that James would choose to play for the Cavaliers next season. Before Cleveland was considered a threat to land LeBron, their championship odds were around 2%, so the 10% Cleveland odds immediately before LeBron’s decision perhaps reflected market expectations that LeBron had a 50% chance of choosing Cleveland: 0.5 * 0.18 + 0.5 *…
  • How much underwear to bring on a trip

    Nathan Yau
    16 Jul 2014 | 2:21 am
    Packing underwear for a short trip is easy. You just pack a pair for each day you're away. However, longer trips require extra planning. Pack a pair for every day, and you get a bag that's too heavy. Pack too few and you have to launder your dirties more often. Reed Kennedy and Carrie Smith gave this problem some extra thought, in search for the ideal underwear count, given the number of days you leave. The result is the chart above. Simply select your trip length on the top, and then move down to find your ideal underwear count. The numbers inside the grid cells indicate how many times you…

    New research reveals the comparative environmental costs of livestock-based foods. While we are told that eating beef is bad for the environment, do we know its real cost? Are the other animal or animal-derived foods better or worse? New research compared the environmental costs of various foods and came up with some surprisingly clear results. The findings will hopefully not only inform individual dietary choices, authors say, but also those of governmental agencies that set agricultural and marketing policies.

    Amphibian decline: Frogs fight back! In the worldwide extinction crisis, the most depressing stories concern amphibians — four-legged animals like frogs and salamanders that undergo metamorphosis to reach their adult form. The International Union for the Conservation of Nature says about 30 percent of the 6,285 amphibian species are threatened with extinction. A Cuban tree frog acquired immunological resistance to the deadly amphibian chytrid fungus during a study just published in Nature.

Supernova SN 2010jl exploded 150 million years ago, sending light carrying clues to the formation of cosmic dust, the building blocks of planets. Photo: European Southern Observatory Dust: It’s the bane of astronomers — since it blocks many wavelengths of light, dimming our view of the universe. But it’s also the source of planets. And that helps explain the excitement about the discovery of masses of dust created within months after a supernova was detected in 2010. By “dust,” astronomers mean tiny…

    A new genetic analysis of people with schizophrenia — and the largest study investigating the genetic basis of any psychiatric disorder to date — provides hints that the disease may sometimes be connected with infections as some researchers have long suggested. There have been few innovative drug treatments for schizophrenia over the last 60 years.

    Before anything else, it is necessary for us to define what test tubes we are talking about. This is because there are different elements associated with the term ‘test tube’. First of all, there are scientific or glass test tubes, whereas the same term is used to denote babies that are born through a procedure called in-vitro fertilization, or test tube babies. Here, the term test tube is being used to denote the test tubes that are typically used in scientific labs. Now, test tubes are also known as sample tubes, or culture tubes.

Thanks to Mother Nature, and her wonderful type IIS endonucleases, this is now possible! What is this wonderful enzyme? Type II enzymes are one of the 4 (I-IV) types of recognized endonucleases (enzymes that cut DNA at a particular recognition site).

    What is immunohistochemistry… Immunohistochemistry (IHC) is a favorite tool amongst clinicians to help diagnose a range of diseases by identifying abnormal cells, such as those in cancer. In a nutshell, IHC uses antibodies to detect proteins (antigens) that are specific to, or have altered expression in, abnormal cells within a tissue section (for example the liver, pancreas or the heart). It can also be used as a predictor for treatment outcome (for example by demonstrating the expression of a target molecule for a particular drug). …and why would you want to use it? IHC isn’t just…

    In the 1980s, concerned that the state statute on prostitution was too broad and could potentially infringe on First Amendment freedoms, lawmakers in Rhode Island decided to make it more explicit by cutting some articles. They went a bit too far, though, and accidentally removed the section defining the act itself as a crime. It wasn’t until 2003 that courts found that they couldn’t prosecute people for prostitution related felonies. Six years later, legislators corrected the law, but during this time it was found that public health and safety improved dramatically. Namely,…

    Whaaaat? It’s just a matter of math, really. Fold an A4 once and it will be twice as thick, fold it again and it will be four times as thick as it initially was. Turns out, according to Dr Karl Kruszelnicki, if you do this 103 times the sheet’s thickness will be larger than the observable Universe: 93 billion light-years.  To do this, however, involves an exponential increase of the necessary energy to fold the paper, which wasn’t computed.

    Harvard’s Houghton Library contains a lush Peter Pan portfolio, a collection of vivid drawings by noted illustrator Arthur Rackham. The dozen detailed images are from the children’s book “Peter Pan in Kensington Gardens,” published by J.M. Barrie in 1906. The work was based on a series of chapters in Barrie’s earlier short story collection from 1902 titled “The Little White Bird,” which featured the first iteration of the character Peter Pan, a little boy who is part bird and never wants to grow up.  
  • Behind ‘Peter Pan’

    18 Jul 2014 | 8:48 am
    In 1904, a kind of lightning struck London’s theater scene. Tuxedo-clad audiences accustomed to somber and serious dramas were stunned by a production set in a whimsical world of make-believe, starring a band of rambunctious children. One well-known actor and producer, after reading an early version of the shocking new play, became convinced its creator had lost his mind. But Scottish playwright J.M. Barrie was perfectly sane when he introduced his land of crocodiles, fairies, pirates, and an ageless, mischievous, flying boy named Peter Pan to the London stage. And theatergoers loved it.

    18 Jul 2014 | 4:30 am
    A single photograph may capture a moment. A collection can open a window to the past. Earlier this year, photograph conservators from the State Hermitage Museum in St. Petersburg, Russia, visited Harvard and shared some treasures held by the Hermitage, many never before seen in the West. Recently, they shared several of these images in digital format. These include rediscovered personal photographs of Russia’s doomed royal family and nobility, hidden following the Revolution or “lost” to storage and transfers over the decades. The Hermitage has embarked on an intense effort to preserve…
  • Tracking Fritz Lang

    17 Jul 2014 | 10:23 am
    For many, the name Fritz Lang is synonymous with the image of a futuristic female robot, the haunting poster child for his 1927 science fiction classic “Metropolis.” But the Austrian-born director was a master of many genres, as visitors to the Harvard Film Archive (HFA) will see for themselves in the coming months. Beginning Friday and running through Sept. 1, the HFA will present a complete retrospective of Lang’s silent and talking feature films. With almost 40 works in total, the series is a tribute to the director’s remarkable range. It includes science fiction, spy thrillers,…

    16 Jul 2014 | 9:27 am
    Seymour Slive, Gleason Professor of Fine Arts Emeritus at Harvard and one of the world’s leading authorities on 17th-century Dutch painting, died in June at the age of 93. Slive had been battling cancer, but was present at Harvard’s May Commencement, where he received an honorary doctor of arts degree. A son of Russian immigrants, Slive was born in Chicago in 1920 and earned both his bachelor’s degree (1943) and his Ph.D. (1952) at the University of Chicago. He put his graduate studies on hold to serve in the Pacific Theater with the U.S. Navy during World War II. A former director of…

    16 Jul 2014 | 10:28 am
    In the first half of the 20th century, scientists faced a vexing  problem. Too many people were being sickened and killed by bacterial endotoxin—a substance in a bacteria’s outer membrane toxic to animals and resistant to heat—contracted through vaccines and surgery tools. The only way to determine if something was contaminated was to test it on animals, a slow and expensive process. In 1956 a scientist named Fred Bang was studying the blood circulation in horseshoe crabs. He observed that when a crab became infected with gram-negative bacteria (a type of bacteria difficult to detect…

    3 Jul 2014 | 10:57 am
    I have a low tolerance for alcohol, which became embarrassingly public on our recent beer webcast. My co-host, Bob, and I were drinking with beer archaeologist Pat McGovern and chemist and home brewer Roger Barth. There was lots of history, culture, and science on the show, as well as actual beer. I found the conversation fascinating, and we didn’t get to talk about half the things we wanted to. But there is one moment that will stick in my memory. I had drunk half my bottle, (the others were on to their second bottle), when I almost knocked over something on the table with my beer glass…
  • A Feast for Mosquitoes

    1 Jul 2014 | 12:27 pm
    We’ve been writing a lot about mosquitoes lately in Chemical Heritage magazine, so blood suckers were on my mind when I was riding a Washington, D.C. Metro train a few weeks ago and noticed a strange advertisement. A poster requested participants in a study to test a potential malaria vaccine delivered by mosquitoes. If you don’t mind letting a malaria-ridden mosquito feast on your blood, you could be paid to be a test subject. Normally mosquitoes are the carriers of malaria, so I was surprised to see them being tested as flying, vaccine-filled syringes. Scientists have not yet…

    16 Jul 2014 | 6:16 am
    Learn more about the different types of opioids in this updated post from 2013. During the 2013 Drug Facts Chat Day, teens from across the country submitted their questions about drug abuse to NIDA scientists. A teen from Walter Johnson High School in Maryland asked: “What types of opioids are there?” Opioids are psychoactive chemicals that occur naturally (in the resin of the poppy plant) or can be made in a laboratory. They work by binding to opioid receptors in the central and peripheral nervous system and the gastrointestinal tract. There are illegal opioids (like heroin) as well as…

    As states continue to pass laws that restrict the sale of e-cigarettes to minors, this post from 2013 explores why they've become so popular with teens. Good news! Cigarette smoking among American teenagers dropped to a record low in 2012. Not so good news—Many teens are turning to a new alternative known as “e-cigarettes.” What Are E-Cigarettes? Electronic cigarettes (e-cigs) are battery-operated products designed to deliver nicotine, flavor, and other chemicals as vapor that a user inhales, without producing actual tobacco smoke.

Nine out of 10 Americans take it in some form every day, and it’s not limited to adults. Hint: According to a recent study published by the American Academy of Pediatrics, nearly three-fourths (75%) of children, teens, and young adults use it daily too—in the form of soda, coffee, and energy drinks.

Have you ever said “It’s not me, it’s my friends?” Turns out, this reasoning may not fly since what your friends do can have a big impact on you. Research studies show that teens whose best friends drink alcohol are twice as likely to try alcohol themselves. And, if teens get alcohol from friends, they’re more likely to start drinking at a younger age. It’s a big deal. We know that a person who…

"This plane is more than a million light years in diameter, but is very thin, with a width of only 300 000 light years. Everywhere we looked we saw this strangely coherent coordinated motion of dwarf galaxies. From this we can extrapolate that these circular planes of dancing dwarfs are universal, seen in about 50 percent of galaxies," Lewis added. "This is a big problem…

    In May 2014, the government of Manitoba was making plans to treat invasive zebra mussels in Lake Winnipeg with potash, a type of fertilizer. Officials didn’t know if the idea would work, but were willing to try given the lake’s losing battle with the invasive. Plans called for four harbors in Lake Winnipeg to be sectioned off and then flooded with the liquid fertilizer. There was plenty of speculation if the treatment would kill off zebra mussels at all, as few studies gave concrete evidence of it working elsewhere. Victoria Beach, Lake Winnipeg.

This plastic is a potential hazard to the health of animals and their ecosystems, and its unsightliness damages the tourism industry that so many people enjoy and depend on for their livelihoods. It is not just the large pieces of plastic that are impacting the Great Lakes ecosystem, although these are bad enough (Figure 1). Figure 1. A fish whose growth was…
  • Water Circulators Used to Combat Invasive Smelt in Crystal Lake

    15 Jul 2014 | 5:32 am
    A mixing experiment appears to have helped clear Wisconsin’s Crystal Lake of invasive smelt, according to WXPR. Researchers at the University of Wisconsin led the investigation. For two years, scientists from Trout Lake Station used GELIs – Gradual Entrainment Lake Inverters – to circulate water in the relatively small lake. Their hypothesis was that circulating the water would invert the lake’s temperature structure, making it inhospitable to the smelt which were harming populations of walleye and yellow perch.

    Connecticut’s Taunton Lake is beset by a large population of Eurasian watermilfoil, according to The Newtown Bee. Experts believe the invasive weed made it there from boaters who transferred it from nearby lakes. These include Lake Zoar, Lake Lillinonah and Candlewood Lake. Eurasian watermilfoil. (Credit: U.S. Fish and Wildlife Service) According to the Connecticut Agricultural Experiment Station, Taunton Lake had a high abundance of native plant Elodea nutalli in its waters in 2009.

  • Careful Management Needed to Ensure Health of Lake Michigan Yellow Perch Fishery

    Daniel Kelly
    10 Jul 2014 | 8:09 am
    The Wisconsin Department of Natural Resources finds that prudent management of Lake Michigan’s yellow perch population is needed for enough spawning stock to survive, according to a release from the organization. It summarizes a recently released report on the issue. Officials at the Wisconsin DNR say that the perch fishery in Lake Michigan is not nearly as good as that existing in the lake during the 1970s. This is due to damages brought about by invasive zebra and quagga mussels, biologists say. Because both types of mussels take nutrients out of the water and concentrate them near the…

  • How to better allocate research money and fix a flawed system

    Julia Lane, Institute fellow at American Institutes for Research
    21 Jul 2014 | 9:21 pm
    Research funding will continue to be haphazard if an anecdotal approach continues to be taken.Lisa S/www.shutterstock.comTaxpayers want to know that their money is well spent on research. Yet funding agencies persist in trying to explain research results in terms of papers and publications rather than in terms of people – which is how the ideas from research affect both science and the economy. Already CSIRO has had more than A$110 million cut in the latest budget and has had its research potential cut back significantly. With almost 500 jobs lost in the last financial year and another 700…

    A new material structure developed at MIT generates steam by soaking up the sun. The structure — a layer of graphite flakes and an underlying carbon foam — is a porous, insulating material structure that floats on water. When sunlight hits the structure’s surface, it creates a hotspot in the graphite, drawing water up through the material’s pores, where it evaporates as steam. The brighter the light, the more steam is generated.read more

    Bee Happy (Photo credit: Treesha Duncan) You’ve probably read a lot of articles in the last year about colony collapse disorder—sudden massive bee hive die-offs. There are a number of different theories about the problem (although nothing has been agreed upon yet), including pesticide use, fungal infection, and disease. What many of the stories have failed to note, however, is that bee populations were in trouble before the disorder made headlines. In the UK, it is estimated that 97% of wildflower meadows have disappeared in the past 60 years and some 20 species of bees have gone…

    Oceans are crucial for supporting Earth-like life on extrasolar planets, according to a study published in the journal Astrobiology. The potential habitability of an exoplanet crucially depends on how its atmospheric and ocean circulation transports heat from warmer to cooler regions. Previous studies have concentrated on modeling the dynamics of atmospheres, while dramatically simplifying the [...]

    When talking about “the style” of an art painting, one usually refers to the materials and colors used in the works. However, specific genres of paintings are advised to be done in specific styles. For example, portraits of generals, kings and noblemen are usually in oil on canvas/panel, while the depiction of maidens or regular people in an alley could be suitable to be painted in pastel, watercolor and other styles. It all depends on how the artist behind the work wants the image to stand out. It takes skill and experience to choose the right style for reproducing one’s imagination…

  • What on earth made these birds give up flying?

    Admin
    13 Jun 2014 | 3:02 am
    Called ratites, the flightless birds are a class by themselves. They show hoe the process of natural selection works. Although losing the ability to fly indicates a retrograde evolutionary step, there’s more to it than meets the eye. Nature’s richest gift to the animal world of prehistoric days was the gift of flight to the reptiles which became birds. From the study of fossils, scientists have determined that birds descended from a group of ground-dwelling dinosaurs known as theropods. The hideous monsters that first began to fly were pterosaurs, i.e. winged reptiles. (Picture, below).

    What are eukaryotes? These are organisms whose cell structure such as organelles is enclosed within the membrane. The nucleus is the defining cell structure that sets eukaryotic cells apart from the prokaryotic cells. The presence of the nucleus gives these organisms their names. Being more complex than Prokaryotes, they make up all fungi, plant, animals such as amoeba. Eukaryotic cells are known for their strong cytoskeleton and their internal membranes. The cytoskeleton is made of proteins like actin and keratin which holds a cell together, differentiating its organelles. Eukaryote means…

The difference is heat is thermal energy transferred from one object to another because of a temperature difference, and temperature is a relative…

    Earlier this year, The Journal of the American Medical Association (JAMA) published a study on how women’s weight before getting pregnant affects their pregnancies. The paper argued that excess weight during pregnancy was associated with large increases in miscarriage and stillbirth. The fact that obesity raises many pregnancy risks — including fetal death — is generally well known. What made this paper striking, however, was that it suggested that the risks increase at much lower weights than previously thought: Based on the authors’ conclusions, you’re better off…

    Let’s say you run a grocery store. One of many problems you’ll face is what to tell your employees about managing food close to expiration. One option is to give them a set of rules (e.g. all fruit is thrown away after three days). Another option is to give them discretion (e.g. look carefully at the fruit after three days, but use your judgment when it comes to deciding what to throw away). The tradeoffs are clear: The rule approach means you’ll lose more fruit, but the discretion approach means there will sometimes be rotting fruit in the mix if your employees don’t do a good…

I've had a great freshman year and I've made some excellent new friends at my high school, but I'm just ready for the year to be over at this point.Read more »
  • On Graham's Number

    8 Jun 2014 | 3:36 pm
         Graham's number, named after its creator, Ronald Graham, is a very, very large number. It is in fact quite a lot larger than you or I can understand. It dwarfs numbers even as huge as googolplex (10^10^100). To see just how staggeringly big Graham's number is, take a look at the Numberphile video below.Read more »

  • Could a blood test predict Alzheimer’s

    Rob Hutchinson
    21 Jul 2014 | 8:56 am
    A major breakthrough has been made in efforts to predict the onset of Alzheimer’s disease, with British scientists discovering a set of proteins that can predict the start of the disease with 87% accuracy. The research in the Alzheimer’s and Dementia Journal is being heralded as the first big development in the field for years, with much of the research since 2002 yielding no useful results. Alzheimer’s is rapidly becoming a problem at the forefront of the medical profession.With an aging population across the globe the number of sufferers is expected to increase dramatically, yet still…

    “I don’t mind doing the Who tours when they come along but I want to get out there and play”, was said by John Entwistle, a renowned musician of English origin. A change in the daily routine Everyone wants to have a time of their life when any such trip is on the cards, be it with family or friends. The need to relax and enjoy the drunken stupor is inevitable, after a long as well as hectic schedule for over half a year. This not only gives the human anatomy, a change in the daily routine but, provides mental relief, which is hard to find these days. More than 50 million people…
  • Cosmic Accounting Reveals Missing Light Crisis

    Carnegie Institution for Science
    16 Jul 2014 | 9:36 am
    Pasadena, CA—Something is amiss in the Universe. There appears to be an enormous deficit of ultraviolet light in the cosmic budget. The vast reaches of empty space between galaxies are bridged by tendrils of hydrogen and helium, which can be used as a precise “light meter.” In a recent study published in The Astrophysical Journal Letters, a team of scientists finds that the light from known populations of galaxies and quasars is not nearly enough to explain observations of intergalactic hydrogen. The difference is a stunning 400 percent. “It’s as if you’re in a big,…
  • Defects in fatty acid transport proteins linked to schizophrenia and autism

    RIKEN
    16 Jul 2014 | 9:30 am
    Using diverse methodologies, neuroscientists from the RIKEN Brain Science Institute report that defects in Fatty Acid Binding Proteins (FABPs) may help to explain the pathology in some cases of schizophrenia and autism spectrum disorders. After identifying mutations in FABPs from patients, the group led by Senior Team Leader Takeo Yoshikawa determined that the genetic disruption of Fabps in mice mimics disease behaviors seen in patients. This work suggests that disruption of FABPs could be a common link underlying some forms of these two prevalent mental disorders. Published in the…
  • Do artists have different brain structures?

    Rob Hutchinson
    7 Jul 2014 | 10:45 am
    It has been a long standing discussion whether men and women are wired differently. Recent research suggests that this is actually true, with men wired front to back in both hemispheres, with only some overlapping connections between the hemispheres, whilst women are connected between the left and right hemispheres. This would explain why generally men are better at learning and performing a single task, but tend to fail miserably at multi-tasking, with women being far better equipped to do more than one thing at once. With this proven, what other discussions regarding brain formations could…

  • How to Mathematically Predict Potential YouTube Views

    Alexander Manzano
    29 Jun 2014 | 1:38 pm
    Recently, I was looking at my YouTube analytics and I noticed a pattern in my statistics. I figured that I can accurately predict potential views in the future by finding a function that closely correlates to my statistics.1. I suggest that you go to your analytics and look at your accumulative views (as shown in the videos). Grab a pen and some paper and write down the values. Your x values will be the number of days, and your y values will be the number of views you have acquired on that day. Copy down these values onto the paper.2. Grab your graphing calculator. I'm using a TI-83 Plus.
  • The Mysterious Matter: Dark Matter

    Alexander Manzano
    23 Jun 2014 | 9:52 pm
    According to the renowned astrophysicist, Neil deGrasse Tyson, there appears to be an unknown substance in the universe that affects gravity--dark matter. Tyson claims that physicists have known about the mysterious matter since the 1930s, and they cannot decipher what this thing is. The word itself--dark matter--can be a misnomer because the thing might not even be matter. Tyson says that it should be named "Fred or some other word that has no meaning" (I paraphrase loosely and I'm sorry if your name is Fred) because scientists truly do not what that mysterious thing that alters gravity…

    In a previous blog, I wrote about math's beauty by talking about rose curves (here's the blog post: Who Said Math Isn't Beautiful?). In contrast to math's feminine beauty, math has a second face; a face that says, "I'm a hardcore vigilante that stops evil at any costs--glorious explosions, deadly weapons, sophisticated gadgets, devious plans, etc.--because I can." A math teacher decided--on his or her free time--to create a piece-wise equation that generates a symbol that is widely known--the famous Batman symbol. The equation (as seen by the very first image of this post)…
  • Einstein's Thought Experiment

    Alexander Manzano
    14 Jun 2014 | 7:18 am
    This morning I woke up in my Buggati, and I was wondering what if my car's speedometer reached the speed of light, 3x10^8 m/s. If my Buggati (I don't really have a Buggati) reached that electromagnetic speed, my car would transform from a Buggati to a DeLorean. However Albert Einstein thought up this scenario with trains or rockets before I did with my fictitious Bugatti.Einstein's thought experiment derived a time-altering equation by using simple mathematics--algebra and the Pythagorean Theorem.In Special Relativity, the speed of light is an universal constant; however, in General…
  • Breaking Mathematics

    Alexander Manzano
    10 Jun 2014 | 5:55 pm
    There are several dimensions in math--the 0th, 1st, 2nd, 3rd, etc. dimensions. The most interesting one is the 0th dimension which is commonly referred to as a single point in space. A point has no dimension which means there is no measure. If you want to find the distance between two points, you will take the final point minus the initial point. For example, let's say that you want to find the distance between 6 and 2. All you have to do is this simple subtraction: 6-2 = 4. Now instead of finding the distance between two points, we want to find the distance of a single point. For example, we…

    21 Jul 2014 | 10:35 am
    By Anupum Pant Of all the creatures in the whole wide world, you’ll be surprised to know that leeches have played a fairly important role in the history of weather forecasting. An incredibly bizarre device invented by Dr. George merry weather, in the 19th century, called the tempest prognosticator, was basically a barometer powered by leeches. Dr. George Merryweather, aptly named, was a surgeon by profession who was a lot into leeches. Since barometers were already being used for a long time then, to indicate approaching storms, he knew that air pressure was crucial in determining…

    By Anupum Pant B.F. Skinner was an American psychologist, a behaviorist, and a social philosopher. He was also the inventor of the operant conditioning chamber – A.K.A the Skinner box, is a box which is used to study animal behaviour. For example, you can use it to train an animal to perform certain actions in response to some input, like light or sound. Using one of his favourite animals, he designed an experiment where he trained a pigeon in order to examine the formation of superstitious beliefs in animals. Here’s what he did. He placed a couple of pigeons in his setup which…
  • The Hottest Place on Earth – Not Death Valley!

    Anupum Pant
    19 Jul 2014 | 10:35 am
    By Anupum Pant For years I’ve known that the death valley was the hottest place on earth. Of course, not counting the lava, laboratory furnaces, hot springs and other such smart-ass answers, the death valley has always been, in textbooks and beyond, the hottest place on our planet. On July 10th 1913, the temperature there was measured to be around 56.7 degrees centigrade. Nowhere else has the mercury risen to such high levels since then. Or so we thought… Until, like always, a science channel from YouTube – MinuteEarth – decided to dive in a little deeper. This is what…

    By Anupum Pant The only desert larger than Sahara is a whole continent which is a desert – Antarctica. But Antarctica, unlike Africa’s desert, isn’t becoming bigger every year. It’s only the Sahara among these two which grows as time passes. So, the expanding Sahara desert poses a great problem for the future generations of the southern nations (Sahel region) towards which it comes creeping. At least the ones just south of the Sahara desert, as the UN suggests, must be ready to face a hard life in the future. Unless, an extremely ambitious and selfless plan being…

    By Anupum Pant Background If you consider the habits, social organization, communities, network of roadways, possession of domestic animals, and counting skills of ants, they are not very different from humans. Yes, ants even domesticate animals. And we’ve talked about their counting skills in the past. Then, I came across a very interesting experiment sir John Lubbock decided to do on ants. Experiment He had in his captivity a number of varieties of ants living in different colonies. One day he saw a group of ants feeding on honey together.

  • Scientists Sequence Novel Bacterial Ecosystems of 396 Human Intestines

    20 Jul 2014 | 1:51 pm
    Researchers at DTU (Technical University of Denmark) in collaboration with an international team from countries including France and China devised a method based on the co-abundance principle to easily identify the genomes (or genetic material) of unknown intestinal microorganisms. The scientists demonstrated this method on 396 human stool samples and uncovered 741 microbial species of which 181 are proposed to be completely novel.  Unlike prior methods to identify bacterial species, the use of CAGs obviates the need for assembly as well the need for a database of reference genomes. The new…

As the media, in particular internet-based media, is considered the first source of information regarding risk for most people, it is vital to understand how it is received around the world. The inherent selectivity of the media means that not all risk events are given fair coverage. When considering natural hazard events, many are given disproportionate responses compared to others of equal severity, and…
