    Gravity-Defying Lanscapes Over millions of years, weathering and erosion of sandstone have produced unique landforms, such as arches, alcoves, pedestals and pillars.  Until now, the natural process remained a mystery.  It was difficult to study, because of the huge time-scales involved in the erosion of natural slabs of sandstone.  Gravity-induced stresses had been assumed not to play any role in landform preservation.  Instead gravity was thought to increase the rates of weathering and natural erosion...   Geologists have now shown that increased stress within a landform, as a result…

    17 Aug 2014 | 3:12 pm
    The Bible tells us we were formed in God's image. So if we are to believe the Bible and take it literally, exactly which of our two visages is it, male or female? Maybe both, or does just one of the sexes contain all the components we need? It is similar to the question "Did the chicken come first, or the egg?" But instead the question is, "Did the male come first, or the female?" The christian Bible strives to answer this question with a story about a man, some mud, and a rib bone. The man was formed out of mud and the woman from the man's rib bone. So therefore the man is said to have come…

  • Did ‘pygmy genes’ help hunter-gatherers survive rainforests?

    A'ndrea Elyse Messer-Penn State
    19 Aug 2014 | 7:29 am
    Batwa hunter-gatherers may have evolved their small statures as a way to live in the rainforest, but probably did so more recently than previously thought. Scientists say the body size associated with the pygmy phenotype is probably a selective adaptation for rainforest hunter-gatherers, but new research indicates that all African pygmy phenotypes don’t have the same genetic underpinnings.

  • Abstinence changes how men define ‘manly’

    Molly McElroy-UW
    19 Aug 2014 | 7:01 am
    Bragging, dirty jokes, and sexual one-upmanship are ways young men, eager to assert their masculinity, often demonstrate their “manhood.” But how does masculinity work for young men who’ve pledged sexual abstinence before marriage? How do they handle sexual temptation, and what sorts of challenges crop up once they’re married? “Sexual purity and pledging abstinence are most commonly thought of as feminine, something girls and young women promise before marriage,” says Sarah Diefendorf, a sociology graduate student at the University of Washington. “But…
  • This fungus turns ants into ‘zombies’

    Chuck Gill-Penn State
    19 Aug 2014 | 6:54 am
    After the “zombie ant fungus” kills a victim, it grows a stalk called the stroma, which protrudes from the ant cadaver. A large round structure, the ascoma, forms on the stroma. Infectious spores then develop in the ascoma and are released onto the forest floor below, where they can infect foraging ants from the colony. (Credit: David Hughes/Penn State) “After climbing vegetation and biting the veins or margins on the underside of leaves, infected ants die, remaining attached to the leaf postmortem, where they serve as a platform for fungal growth,” says lead author…

    News Staff

    The antibiotic clarithromycin is widely used for treating common bacterial infections and has been linked to an increased risk of heart deaths by a study on BMJ. The absolute risk is small and prescribing practice should not be changed until results have been confirmed in an independent study but the authors say their findings require urgent confirmation, given that many millions of people are prescribed the drug each year.  read more

Globalization used to be controversial but by now no one sentient really thinks cultures that condone rape and stoning of women should be preserved.Cloud computing will take that globalization to the next level, because it is a key enhancer of innovation and economic development - and it gives groups without giant budgets for hardware a way to compete, just like food science that lets crops grow in inhospitable…

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

    One of the first things I do in the morning is check the front pages of the daily papers and on the day following Robin Williams’ death, rarely have I been so disappointed in the British press. Over the years, we have gathered a lot of evidence from reliable studies that show that how suicide is reported in the mass media affects the chances of suicide in the population – likely due to its effect on vulnerable people. In other words, sensationalist and simplistic coverage of suicides, particularly celebrity suicides, regularly leads to more deaths. It seems counter-intuitive to many, that…

A paradigmatic example is the bistable expression of virulence genes in Salmonella typhimurium, which leads to phenotypically virulent and phenotypically avirulent subpopulations. The two subpopulations have been shown to divide labor during S. typhimurium infections. Here, we show that heterogeneous virulence gene expression in this…
  • The Cytoplasmic Capping Complex Assembles on Adapter Protein Nck1 Bound to the Proline-Rich C-Terminus of Mammalian Capping Enzyme

    Chandrama Mukherjee et al.
    19 Aug 2014 | 2:00 pm
    by Chandrama Mukherjee, Baskar Bakthavachalu, Daniel R. Schoenberg Cytoplasmic capping is catalyzed by a complex that contains capping enzyme (CE) and a kinase that converts RNA with a 5′-monophosphate end to a 5′ diphosphate for subsequent addition of guanylic acid (GMP). We identify the proline-rich C-terminus as a new domain of CE that is required for its participation in cytoplasmic capping, and show the cytoplasmic capping complex assembles on Nck1, an adapter protein with functions in translation and tyrosine kinase signaling.

  • Pyramidal Cells Make Specific Connections onto Smooth (GABAergic) Neurons in Mouse Visual Cortex

    Rita Bopp et al.

    by Rita Bopp, Nuno Maçarico da Costa, Björn M. Kampa, Kevan A. C. Martin, Morgane M. Roth One of the hallmarks of neocortical circuits is the predominance of recurrent excitation between pyramidal neurons, which is balanced by recurrent inhibition from smooth GABAergic neurons. It has been previously described that in layer 2/3 of primary visual cortex (V1) of cat and monkey, pyramidal cells filled with horseradish peroxidase connect approximately in proportion to the spiny (excitatory, 95% and 81%, respectively) and smooth (GABAergic, 5% and 19%, respectively) dendrites found in the…

    by René F. M. van Oers, Elisabeth G. Rens, Danielle J. LaValley, Cynthia A. Reinhart-King, Roeland M. H. Merks In vitro cultures of endothelial cells are a widely used model system of the collective behavior of endothelial cells during vasculogenesis and angiogenesis. When seeded in an extracellular matrix, endothelial cells can form blood vessel-like structures, including vascular networks and sprouts. Endothelial morphogenesis depends on a large number of chemical and mechanical factors, including the compliancy of the extracellular matrix, the available growth factors, the adhesion of…
  • Optimal Behavioral Hierarchy

    Alec Solway et al.
    14 Aug 2014 | 2:00 pm
    by Alec Solway, Carlos Diuk, Natalia Córdova, Debbie Yee, Andrew G. Barto, Yael Niv, Matthew M. Botvinick Human behavior has long been recognized to display hierarchical structure: actions fit together into subtasks, which cohere into extended goal-directed activities. Arranging actions hierarchically has well established benefits, allowing behaviors to be represented efficiently by the brain, and allowing solutions to new tasks to be discovered easily. However, these payoffs depend on the particular way in which actions are organized into a hierarchy, the specific way in which tasks are…
  • Kinetic Memory Based on the Enzyme-Limited Competition

    Tetsuhiro S. Hatakeyama et al.
    14 Aug 2014 | 2:00 pm
    by Tetsuhiro S. Hatakeyama, Kunihiko Kaneko Cellular memory, which allows cells to retain information from their environment, is important for a variety of cellular functions, such as adaptation to external stimuli, cell differentiation, and synaptic plasticity. Although posttranslational modifications have received much attention as a source of cellular memory, the mechanisms directing such alterations have not been fully uncovered. It may be possible to embed memory in multiple stable states in dynamical systems governing modifications. However, several experiments on modifications of…
  • The Protective Role of Symmetric Stem Cell Division on the Accumulation of Heritable Damage

    Peter T. McHale et al.
    14 Aug 2014 | 2:00 pm
    by Peter T. McHale, Arthur D. Lander Stem cell divisions are either asymmetric—in which one daughter cell remains a stem cell and one does not—or symmetric, in which both daughter cells adopt the same fate, either stem or non-stem. Recent studies show that in many tissues operating under homeostatic conditions stem cell division patterns are strongly biased toward the symmetric outcome, raising the question of whether symmetry confers some benefit. Here, we show that symmetry, via extinction of damaged stem-cell clones, reduces the lifetime risk of accumulating phenotypically silent…
  • Epigenetic Landscapes Explain Partially Reprogrammed Cells and Identify Key Reprogramming Genes

    Alex H. Lang et al.
    14 Aug 2014 | 2:00 pm
    by Alex H. Lang, Hu Li, James J. Collins, Pankaj Mehta A common metaphor for describing development is a rugged “epigenetic landscape” where cell fates are represented as attracting valleys resulting from a complex regulatory network. Here, we introduce a framework for explicitly constructing epigenetic landscapes that combines genomic data with techniques from spin-glass physics. Each cell fate is a dynamic attractor, yet cells can change fate in response to external signals. Our model suggests that partially reprogrammed cells are a natural consequence of high-dimensional landscapes,…

  • EVA-1 Functions as an UNC-40 Co-receptor to Enhance Attraction to the MADD-4 Guidance Cue in Caenorhabditis elegans

    Kevin Ka Ming Chan et al.
    14 Aug 2014 | 2:00 pm
    by Kevin Ka Ming Chan, Ashwin Seetharaman, Rachel Bagg, Guillermo Selman, Yuqian Zhang, Joowan Kim, Peter J. Roy We recently discovered a secreted and diffusible midline cue called MADD-4 (an ADAMTSL) that guides migrations along the dorsoventral axis of the nematode Caenorhabditis elegans. We showed that the transmembrane receptor, UNC-40 (DCC), whose canonical ligand is the UNC-6 (netrin) guidance cue, is required for extension towards MADD-4. Here, we demonstrate that MADD-4 interacts with an EVA-1/UNC-40 co-receptor complex to attract cell extensions. EVA-1 is a conserved transmembrane…

    by Aaron C. Wacholder, Corey Cox, Thomas J. Meyer, Robert P. Ruggiero, Vijetha Vemulapalli, Annette Damert, Lucia Carbone, David D. Pollock Most common methods for inferring transposable element (TE) evolutionary relationships are based on dividing TEs into subfamilies using shared diagnostic nucleotides. Although originally justified based on the “master gene” model of TE evolution, computational and experimental work indicates that many of the subfamilies generated by these methods contain multiple source elements. This implies that subfamily-based methods give an incomplete picture of…

  • Inhibition of the TRAIL Death Receptor by CMV Reveals Its Importance in NK Cell-Mediated Antiviral Defense

    Shilpi Verma et al.
    14 Aug 2014 | 2:00 pm
    by Shilpi Verma, Andrea Loewendorf, Qiao Wang, Bryan McDonald, Alec Redwood, Chris A. Benedict TNF-related apoptosis inducing ligand (TRAIL) death receptors (DR) regulate apoptosis and inflammation, but their role in antiviral defense is poorly understood. Cytomegaloviruses (CMV) encode many immune-modulatory genes that shape host immunity, and they utilize multiple strategies to target the TNF-family cytokines. Here we show that the m166 open reading frame (orf) of mouse CMV (MCMV) is strictly required to inhibit expression of TRAIL-DR in infected cells. An MCMV mutant lacking m166…

Alan Wilson Schistosomes are parasitic flatworms that infect >200 million people worldwide, causing the chronic, debilitating disease schistosomiasis. Unusual among parasitic helminths, the long-lived adult worms, continuously bathed in blood, take up nutrients directly across the body surface and also by ingestion of blood into the gut. Recent proteomic analyses of the body surface revealed the presence of hydrolytic enzymes, solute, and ion transporters, thus emphasising its metabolic credentials. Furthermore,…

Savarino, Di Xia Adhesive pili on the surface of pathogenic bacteria comprise polymerized pilin subunits and are essential for initiation of infections. Pili assembled by the chaperone-usher pathway (CUP) require periplasmic chaperones that assist subunit folding, maintain their stability, and escort them to the site of bioassembly. Until now, CUP chaperones have been classified into two families, FGS and FGL, based on the short and long length of the subunit-interacting loops between its F1 and G1 β-strands, respectively.

    by Aisulu Zhussupova, Tetsu Hayashida, Maiko Takahashi, Kazuhiro Miyao, Hiroshi Okazaki, Hiromitsu Jinno, Yuko Kitagawa Homeobox B9 (HOXB9), a member of the homeobox gene family, is overexpressed in breast cancer and promotes tumor progression and metastasis by stimulating epithelial-to-mesenchymal transition and angiogenesis within the tumor microenvironment. HOXB9 activates the TGFβ-ATM axis, leading to checkpoint activation and DNA repair, which engenders radioresistance in breast cancer cells. Despite detailed reports of the role of HOXB9 in breast cancer, the factors that regulate HOXB9…

    19 Aug 2014 | 9:59 am
    In comparison with 'best supportive care', there is an indication that the new drug is better at relieving symptoms, and a hint of longer survival. Myelofibrosis is a rare disease of the bone marrow, in which the bone marrow is replaced by connective tissue. As a consequence of this so-called fibrosis, the bone marrow is no longer able to produce enough blood cells. Sometimes the spleen or the liver takes over some of the blood production. Then these organs enlarge and can cause abdominal discomfort and pain.

    Planet discoveries boost LifeSearch 2.0 A newly discovered planet dubbed “mega-Earth” is shown in an artist’s conception. Kepler-10c orbits a sun-like star, has a diameter of about 29,000 kilometers (2.3 times larger than Earth), and weighs 17 times more. The solid planet may have a thin atmosphere that is unlikely to support life. 10c is located about 560 light years away and orbits its star every 45 days. Photo: David A.

Does aeronautical engineering respond to the same basic physics that governs bird evolution? Photo: Boeing Evolution through natural selection governs the “design” of flying creatures. Engineers design flying machines. But flying is about physics, and physics is the ultimate arbiter of both processes, says Adrian Bejan, a professor of mechanical engineering at Duke University. And that produces parallels in mechanical and animal evolution. In…

    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.

  • Scientists warn Florida governor of threat from climate change

    19 Aug 2014 | 4:18 pm
    By Bill Cotterell TALLAHASSEE Fla. (Reuters) - Five climate scientists warned Florida Governor Rick Scott in a meeting on Tuesday that a steadily rising ocean was a major threat to the state's future, urging it to become a leader in developing solar energy and other clean power sources. The Republican governor, who disputed the human impact on climate change in his 2010 campaign, agreed recently to meet with the scientists after his main Democratic challenger for re-election this year, former Governor Charlie Crist, proclaimed himself a firm believer in global warming. “I’m inherently an…
  • Flu Shot Recommended for All Pregnant Women

    19 Aug 2014 | 2:22 pm
    Pregnant women should get the flu shot, regardless of how far along they are in their pregnancies, according to updated guidelines released by the American College of Obstetricians and Gynecologists (ACOG). The new guidelines by ACOG also state that vaccination is important for women who are trying to become pregnant. Preventing the flu is an essential element of care during preconception, as well as during pregnancy and after delivery, according to a statement from ACOG. "The flu virus is highly infectious and can be particularly dangerous to pregnant women, as it can cause pneumonia,…
  • Like a Virgin: Chaste Men Sexually Confused After Marriage

    19 Aug 2014 | 10:15 am
    Men who make virginity pledges get strong social support to abstain from sex before the wedding night, but that backing disappears soon after they tie the knot, new research suggests. As a result, male virginity pledgers can be somewhat confused and lost when it comes to sex after marriage, said study researcher Sarah Diefendorf, a sociology doctoral candidate at the University of Washington in Seattle. "They spend the first 20-something years of their lives being told that sex is wrong," Diefendorf told Live Science. Small, focused groups who make virginity pledges have a better track record…
  • 'Beam Me to Mars' Lets You Send Martian Messages to Fund Space Exploration

    19 Aug 2014 | 8:58 am
    The space-funding company Uwingu launched its "Beam Me to Mars" project today (Aug. 19), inviting people to contribute, for a fee, to a "digital shout-out" that will send messages from Earth to the Red Planet on Nov. 28 — the 50th anniversary of Mars exploration.

  • Kids' Drawings May Paint a Picture of Later Intelligence

    Their ability to draw a picture of a child may be linked to their intelligence at age 14, a new study suggests. The study, which involved more than 7,700 pairs of identical and nonidentical twins, found that genes play a role in the link between early drawing ability and later measures of intelligence. "The correlation is moderate, so our findings are interesting, but it does not mean that parents should worry if their child draws badly," Dr. Rosalind Arden, a professor of psychiatry at King's College London, in the U.K., and lead author of the study published yesterday (Aug.

    Emily Underwood
    14 Aug 2014 | 5:00 pm
    Expectant mothers are barraged with advice from friends, family, and physicians about what to eat while pregnant and breast-feeding. Most of that advice is focused on nutrition, but in recent years scientists have begun to explore another important aspect of early food experience—flavor. Although some preferences, such as a love for sweetness and an aversion to bitterness, are genetically determined, a growing body of evidence suggests that the majority of our idiosyncratic inclinations for different flavors are not innate, but rather learned. Indeed, studies in human infants and animals…
  • [Special Issue News] Parenting: Unsettled questions trail IVF's success

    Kelly Servick
    14 Aug 2014 | 5:00 pm
    In vitro fertilization (IVF) and associated techniques are a medical success story, with more than 5 million apparently healthy babies born this way. The known risks of these technologies are relatively small: a slight increase in pregnancy complications, preterm birth, and low birth weight, and possibly an increased risk of birth defects. But as researchers learn more about the sensitivity of early embryos, they have begun to wonder if the manipulations of IVF may have additional subtle effects that appear as children grow. Animal studies hint that people conceived this way may be at higher…

    The study of mother's milk is booming, thanks to new analytical techniques, a growing interest in milk-microbiome connections, and the resurgence of breast-feeding. Building upon a century-old study that first indicated that milk nourished certain bacteria in infants, the new work has characterized the complexity of breast milk carbohydrates called oligosaccharides, or HMOs, that particularly nourish one species of beneficial bacteria. That microbe in turn encourages the growth of other beneficial bacteria and promotes a healthy gut immune system. These HMOs also protect the gut against…

    A study of orphans carried out in Bucharest has been described as the best controlled—and most controversial—analysis of institutionalized child care. Led by Harvard Medical School neuroscientist Charles Nelson, the Bucharest Early Intervention Project (BEIP) tracks children who were raised for a time with essentially no parenting. BEIP intervened in 2000 to offer high-quality foster care to a randomly selected group of these Romanian orphans; it also tracked a group who lived in institutions. (This was controversial; some critics thought that it was improper to study any children in…

    No, this is not a call for Geeks to take over the world – just a tiny part of it – the part that ensures success in all experiments or at least a good way to analyze them if they fail. There are all too many entry points for error and variability that can be introduced into experimental measurements – and it's critical to control those points. This is especially true in Flow Cytometry where there are multiple controls essential for proper interpretation of the data. Flow cytometry controls can be divided into 5 major classes. The purpose of these controls to ensure the instrument…
  • Help: My Gal Promoter Doesn’t Work

    Aunt Yersinia
    18 Aug 2014 | 12:00 am
    Dear Aunt Yersinia, I work with a yeast vector where my gene is under a Gal promoter. My boss told me to grow yeast in medium with sucrose, and then add galactose to induce the promoter. I did it, but my protein is not induced; the Western blot is empty. I sequenced a part of the vector and found out that the promoter and the gene are correct. What can I do? Anni   Dear Anni, The Gal1 promoter from fission yeast is used in many vectors for regulated gene expression. The working of the promoter is caused by the fact that for yeast, nothing beats glucose as a source of carbon and energy.

    If you ever used a site-directed mutagenesis kit or ligation-independent cloning, then you also used restriction enzyme Dpn I. But what does it do and more interestingly, why? Restriction enzymes and methylases: the yin and yang of bacteria Usual restriction enzymes, the toolkit of genetic engineering, are one half of the “yin and yang” pair of enzymes, which together with a methylase make up a restriction-modification system. Both members of the pair recognize one sequence in the DNA. Methylase modifies the DNA sequence by adding a methyl group to a specific nucleotide. In nature, methyl…

  • Is empathy in humans and apes actually different?

    19 Aug 2014 | 12:00 am
    Whether or not humans are the only empathic beings is still under debate. In a new study, researchers directly compared the 'yawn contagion' effect between humans and bonobos -- our closest evolutionary cousins. By doing so they were able to directly compare the empathic abilities of ourselves with another species, and found that a close relationship between individuals is more important to their empathic response than the fact that individuals might be from the same species.

    Pump jacks dot oil fields between the California towns of Taft and Maricopa. The very deep petroleum would be hard to reach. Methods such as fracking would bring environmental concerns and no guarantees. Photo: Los Angeles Times A while ago I wrote about the disheartening status quo of energy today: frack now, ask questions later.

  • This bacterium shoots wires out of its body to power itself

    Mihai Andrei
    19 Aug 2014 | 12:11 pm
    This bacterium has a lot in common with power companies. Power companies use copper wires to channel electricity (and therefore, electrons), and this bacterium developed a mechanism to do something similar: in the absence of oxygen, it grows nanowires from its own body through which it pushes electrons to nearby rocks. This is how it obtains energy, as opposed to almost all organisms, which use internal processes to produce their energy. This being said though, researchers have long known that bacteria can swap electrons with minerals, but the details and specific cases were quite rare. Even…

In leucism however, there is a reduction in all types of skin pigment, not just melanin. A further difference between albinism…

    The earth is vast and its surface seems huge. However, the earth’s crust only makes up 1% of the earth’s mass — subsequent layers (the mantle and the core) make up the other 99%. So, why do we care about the earth’s crust (besides the fact that we live there)? It consists of tectonic plates that move around, and where they hit, we get nature’s most impressive formations — Earthquakes and Volcanoes. Because the crust is so vast, it is hard to see the minor changes that occur daily. We tend to notice the big changes like mountains and effects from earthquakes. In Houston, we…

     Most people associate earthworms with nutrient-rich soil, healthy gardens, and compost piles. It turns out these creatures, which can be so helpful to backyard gardeners, may be harming North American forests. Researchers suspect that the last ice age wiped out the vast majority of earthworm species in North America; almost no native earthworms can be found living in parts of the continent once covered by glaciers. European settlers reintroduced earthworms to regions that had developed worm-free ecosystems for thousands of years. Many of the worms likely hitched a ride in the soil used for…

In a new study, researchers used laser optical tweezers to study interactions between the disease-causing parasite and red blood cells. The findings reveal surprising new insights into malaria biology and pave the way for the development of more effective drugs or vaccines for a disease that affects hundreds of millions of people around the world.

  • Exporting US coal to Asia could drop emissions 21 percent

    18 Aug 2014 | 9:00 pm
    Under the right scenario, exporting US coal to power plants in South Korea could lead to a 21 percent drop in greenhouse gas emissions compared to burning it at less energy-efficient US plants. Other emissions, including sulfur dioxide, nitrogen oxide and particulate matter, could also drop. But this success, Duke researchers say, depends on which fuel source the coal replaces in South Korea, and which fuel is used to replace it in the US.

  • Harvard Astronomers Study Mystery Signal from No Known Element --"Is it the Long-Sought Dark Matter Particle?"

    dailygalaxy.com
    19 Aug 2014 | 7:07 am
    It came as something of a surprise when Center for Astrophysics astronomers and their colleagues discovered a faint line corresponding to no known element. Esra Bulbul, Adam Foster, Randall Smith, Scott Randall and their team were studying the averaged X-ray spectrum of a set of seventy-three clusters (including Virgo above) looking for emission lines too faint to be seen in any single one when they uncovered a line with no known match in a particular spectral interval not expected to have any features. The scientists propose a tantalizing suggestion: the line is the result of the decay of a…

    The universe has so many black holes that it’s impossible to count them all. There may be 100 million of these intriguing astral objects in our galaxy alone. Nearly all black holes fall into one of two classes: big, and colossal. Astronomers know that black holes ranging from about 10 times to 100 times the mass of our sun are the remnants of dying stars, and that supermassive black holes, more than a million times the mass of the sun, inhabit the centers of most galaxies.

  • High School Senior’s Class Project Finds Lake Champlain Is On The Rise

    Daniel Kelly
    14 Aug 2014 | 8:44 am
    Utilizing public data available from the U.S. Geological Survey, high school senior Brendan Murphy has found that Lake Champlain has risen nearly a foot since 1971, according to Seven Days Vermont. His work confirms what many living near the lake have observed for decades. During the early ‘70s, Lake Champlain’s average water level was 95.5 feet above sea level, assessed by researchers at the University of Vermont using technology of the era. That number, outdated today, has been used as a legal standard in property disputes and zoning issues well into the 21st century. Sail boats on Lake…

  • Study to Focus On Lake Tahoe’s Threatened Nearshore Waters

    A lot of research has focused on the deep waters of Lake Tahoe, with recent work finding the lake’s long-term clarity has seemingly stabilized. But most people never make it out to its middle on a research boat. They’re more familiar with the waters they see washing up on the beach. These nearshore waters, scientists say, are incredibly complex. Compared to Lake Tahoe’s deep waters, they are in the crosshairs of stormwater flow and runoff and are battling aquatic invasive species like zebra mussels, quagga mussels and non-native snails.

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

Cleveland, like many Rust Belt cities hit hard by the foreclosure crisis, is speckled with abandoned homes and vacant lots. Many of the properties are beyond repair. A biocellar is a way to salvage the foundation of a house and put it to productive reuse. With permaculture designer Jean Loria and architect Robert Donaldson, Frazier carefully deconstructed…
  • Shrimp from Wisconsin? New Aquatic Farming Methods Are Making It Possible

    7 Aug 2014 | 7:00 am
    Forbes Adam says one of the reasons he started Dairyland Shrimp was to provide his family with a safer product that he trusted. (Maureen McCollum/WPR) The aquaculture industry in Wisconsin could be in for a boost, as techniques for growing marine life in artificial ponds are leading to the state's first indoor shrimp farm. Every morning inside a big red building near downtown Westby, you'll find Forbes Adam feeding his 14,000 shrimp. These shrimp are about two months old. Forbes Adam gets the juveniles from Matt Weichers at Northern Iowa Shrimp, which raises the larvae in a…
  • The Future of Sustainable Food: Q&A with Wendell Berry

    Liz Roth-Johnson
    5 Aug 2014 | 7:00 am
    Photo by Guy Mendes Farmer and environmentalist Wendell Berry is known to many as the father of the sustainable food movement. He is an outspoken advocate for an agrarian revolution to end industrialized practices that he says are poisoning the land and destroying rural communities. In recent years Berry has promoted a 50-Year Farm Bill, which presents a long-term plan to reduce soil erosion and land pollution by replacing annual crops with perennials. His latest book, Distant Neighbors, chronicles his 40-year correspondence with poet Gary Snyder, and discusses everything from faith and…

  • How Ebola blocks immune system

    LaboratoryNews
    19 Aug 2014 | 2:05 am
    American researchers have developed a detailed map of the Ebola protein VP24, which has revealed how the virus dodges the body’s antiviral defences – an insight which could lead to new therapies. VP24 binds to a host protein that takes signalling molecules in and out of the cell nucleus, say researchers from Washington University in St Louis. The map reveals the viral protein removes the host protein’s ability to carry an important immune signal to the nucleus. This signal helps to activate antiviral defences, and blocking it is believed to contribute significantly to Ebola’s…

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

They are quiet, independent and clean engines. Here, batteries store free energy from the sun.The available sunlight is converted into electric power by solar cells which is temporarily stored in batteries. It is used to drive a propeller through an electric motor. Typically, power levels are within a few hundred watts to a few kilowatts. A specific solar boat can run on solar energy depends on its technical design, the amount of…

    What is Bio plastics?Bio plastics are the bio based plastics produced from renewable resources like corn starch, pea starch, vegetable fats and oils. On the other hand, conventional plastics or fossil fuel plastics are produced from petroleum. Conventional plastics create more greenhouse gas which is very dangerous for our environment. Petroleum is very limited resource in the earth. It becomes expensive day by day. One day, this resource will be finished. During burning petroleum products like plastics, carbon is emitted and it causes the climate change. Conventional plastics are harmful…

    Psychology is a vast field with many researchers, scientists and collaborators working through the past two hundred or so years to advance our knowledge, so it’s not surprising that with so many people involved some of the famous contributors tend to slide away out of view. Otto Selz is one of them. The strange thing about his case is that he broke new ground in the area of cognitive psychology, and deserves to be remembered for his contribution. The likes of Noam Chomsky and Allen Newell are frequently credited with starting the cognitive revolution but it was Selz and his contemporaries…
  • Breaking social norms – Does it feel good?

    Rob Hutchinson
    7 Aug 2014 | 7:43 am
    Not so long ago in my first year of studying Psychology at university we were given the task of breaking a social norm and recording people’s responses to it. A social norm is an expected behaviour pattern within a society in given situations, for example in almost every society there is the social norm that in the cinema you don’t answer your mobile phone or shout out in the middle of the movie. Social norms can be something as small and insignificant as using a knife and fork to eat with and not our hands or forming a queue for the bus. Norms build the fabric of our everyday existence…

    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…

    By Anupum Pant Certain kinds of similar trees can be grafted onto each other into a single tree which produces all of the grafted fruits. For example oranges and lemons trees can be grafted onto each other, but not apple and oranges. In fact there is a company I found on the internet that sells such trees. They call them the fruit salad trees. Usually such companies stop at a point where they have about 6-8 different fruits grafted on to a single tree. However, one person, Sam Van Aken wanted to save a few varieties of fruits which could have otherwise been lost for ever. He grafted 40 of…
  • Reproducing Sound From a Video of Leafs

    Anupum Pant
    17 Aug 2014 | 10:35 am
    By Anupum Pant Sound is a series of compressions and rarefactions travelling through a medium. It is actually a physical entity. When sound moves, physical object, like the molecules of air move. So, when sound hits an object, it makes the object move. But the movements a normal volume sound can produce in an object are really very tiny. Most times the naked eye sees no difference. However if the tiny movements can be sensed by a very sensitive algorithm by processing data from a video of that object, the sound can probably be reproduced to some extent. A few researchers at MIT did just that.

It started in the year 1971 when soviet scientists set up a rig to extract natural gas at that place, and the rig collapsed. When that happened, the scientists feared the spread of huge amounts of methane gas, and set the place on fire. They estimated that the fire would go out in a couple of hours. But it lasted, and has lasted for more than 40 years. The fire in it is still burning strong. The hole is in a very isolated…

Since the 80s several attempts have been made to climb this mountain – a part of which lies in Bhutan and the other part in Tibet. None of the attempts have ever been successful. However in the year 1999, a team of climbers from Japan, after a protracted attempt to get a permit, were able to reach the top of one of the three peaks - Liankang Kangri – from the Chinese side of the mountain.

    When pathogens invade the body, the immune system kicks into gear and sends out swarms of cells to fight the invader.  These swarms consist of two types of cells; fighters, known as killer T cells, and peacemakers, known as regulatory T cells, sometimes referred to as Tregs.  The purpose of the Tregs is to send a signal to the killer cells to stop the attack when the pathogen has been eliminated.  Without a signal from the Tregs, when the pathogen is gone, the killer T cells turn their attack on the body, resulting in everything from inflammation to allergies, asthma, MS, rheumatoid…

    The Bible tells us we were formed in God's image. So if we are to believe the Bible and take it literally, exactly which of our two visages is it, male or female? Maybe both, or does just one of the sexes contain all the components we need? It is similar to the question "Did the chicken come first, or the egg?" But instead the question is, "Did the male come first, or the female?" The christian Bible strives to answer this question with a story about a man, some mud, and a rib bone. The man was formed out of mud and the woman from the man's rib bone. So therefore the man is said to have come…

Currently, 176 of those species occur in the United States. Mosquitoes are insects and belong to the order Diptera, and as such are an example of True Flies. Some are harmless or even beneficial to the human race, but many are considered pests due to the fact that the females of the species use the blood of vertebrates to feed.
