  • China says massive area of its soil polluted
    A man shovels earth in a field outside a power plant in Xingtai, southern Hebei province, on March 10, 2013 A huge area of China’s soil covering more than twice the size of Spain is estimated to be polluted, the government said Thursday, announcing findings of a survey previously kept secret. Of about 6.3 million square kilometres (2.4 million square miles) of soil surveyed—roughly two thirds of China’s total area—16.1 percent is thought to be polluted, the environmental protection ministry said in a report. The study, which appeared on its website, blamed mining and farming practices among other causes. “The national soil pollution situation is not positive,” the ministry said, adding that more than 19 percent of the farmland which was surveyed is polluted. The ministry last year described the results of its soil pollution survey as a state secret and refused to release the results, a move which incensed environmental campaigners. The government has come under increasing pressure in recent years to take action to improve the environment, with large parts of the country repeatedly blanketed in thick smog and waterways and land polluted. In response to public pressure, China has released more accurate data about air pollution. Read more at: Phys.org … Read more

  • For resetting circadian rhythms, neural cooperation is key
    Fruit flies are pretty predictable when it comes to scheduling their days, with peaks of activity at dawn and dusk and rest times in between. Now, researchers reporting in the Cell Press journal Cell Reports on April 17th have found that the clusters of brain cells responsible for each of those activity peaks—known as the morning and evening oscillators, respectively—don’t work alone. For flies’ internal clocks to follow the sun, cooperation is key. “Without proper synchronization, circadian clocks are useless or can even be deleterious to organisms,” said Patrick Emery from the University of Massachusetts Medical School. “In addition, most organisms have to detect changes in day length to adapt their rhythms to seasons. … Read more
  • A sharp eye on Southern binary stars
    Unlike our sun, with its retinue of orbiting planets, many stars in the sky orbit around a second star. These binary stars, with orbital periods ranging from days to centuries, have long been the primary tool for measuring basic quantities like the star’s mass. While masses of normal stars are now well determined, some binaries present special interest because their stars are unusual (e.g. very young) or because they may contain planets, gas clouds, or other stars. … Read more

  • Structure of sodium channels different than previously believed
    Sodium channels are implicated in many serious conditions such as heart disease, epilepsy and pain, making them an important potential target for drug therapies. Unfortunately, there is still much scientists do not know about the molecules. New Cambridge research provides fresh and unexpected insight into the structure of sodium channels and, specifically, one of its components – β-subunit molecules – which are responsible for ‘fine-tuning’ the activity of the channel. The research is published in the most recent edition of the Journal of Biological Chemistry. … Read more
  • Fear of the cuckoo mafia
    If a restaurant owner fails to pay the protection money demanded of him, he can expect his premises to be trashed. Warnings like these are seldom required, however, as fear of the consequences is enough to make restaurant owners pay up. Similarly, mafia-like behaviour is observed in parasitic birds, which lay their eggs in other birds’ nests. If the host birds throw the cuckoo’s egg out, the brood parasites take their revenge by destroying the entire nest. Consequently, it is beneficial for hosts to be capable of learning and to cooperate. Previously seen only in field observations, scientists at the Max Planck Institute for Evolutionary Biology in Plön have now modelled this behaviour mathematically to confirm it as an effective strategy. … Read more

  • Scientists solve the case of the red abalone die-off using forensic genomics
    Dead red abalone lie on a beach among the rocks at Fort Ross, Calif., in 2011. Researchers at UC Davis used forensic genomics to learn that the mass die-off was due to an algal bloom. (Nate Buck/courtesy photo)     In August 2011, thousands of dead red abalone washed up on the beaches of Sonoma County in Northern California. At the time, the cause was unknown, but scientists, including a biologist from the University of California, Davis, learned that a harmful algal bloom was to blame: the causative agent Yessotoxin. While discovery of the cause itself is noteworthy, the method by which it was determined could have a profound effect on how wildlife mortality events are investigated in the future. Described in a study published today, April 16, in the journal Nature Communications, the researchers call this new approach “forensic genomics.” It involves a combination of field surveys, toxin testing and genomic scans. … Read more

  • Neurons in the brain tune into different frequencies for different spatial memory tasks
    Place cells in the hippocampus provide a neuronal code for specific locations in space. Place cells codes represent upcoming locations at some times and reflect recently visited locations at other times. The findings by Bieri and colleagues show that place cells predict upcoming locations during periods of slow gamma rhythms and encode recently visited locations during periods of fast gamma rhythms. Illustration credit: Juliette Pepperell.     Your brain transmits information about your current location and memories of past locations over the same neural pathways using different frequencies of a rhythmic electrical activity called gamma waves, report neuroscientists at The University of Texas at Austin. The research, published in the journal Neuron on April 17, may provide insight into the cognitive and memory disruptions seen in diseases such as schizophrenia and Alzheimer’s, in which gamma waves are disturbed. … Read more

  • Clean air: Fewer sources for self-cleaning
    Up to 1,000 meters above the ground: as part of the EU project PEGASOS, Jülich scientists and their colleagues spent five weeks recording data with the Zeppelin NT in the atmosphere over northern Italy. During their campaign, the researchers identified a previously unknown process that leads to the formation of the trace gas nitrous acid (HONO). Data analysis led to a surprising finding: in contrast to the prevailing assumption, HONO is not an additional source of hydroxyl radicals (OH radicals), which play an important role in the atmosphere’s self-cleaning capacity. Credit: Source: Forschungszentrum Jülich/ Florian Rubach     Up to now, HONO, also known as nitrous acid, was considered one of the most important sources of hydroxyl radicals (OH), which are regarded as the detergent of the atmosphere, allowing the air to clean itself. A research group from Jülich has put an end to this conception. The new hypothesis is based on air measurements recorded by a Zeppelin NT within the framework of the EU PEGASOS project. The prevailing assumption about the role of HONO in atmospheric chemistry as a pure source of radicals now has to be completely overhauled. The results have appeared in the peer-reviewed journal Science. … Read more

  • Turning off depression in the brain
    Researchers produced antidepressant-like behavioral effects by reversing out-of-balance electrical activity in reward circuit neurons of susceptible mice exposed to social stress. Further increasing an excitatory current (lh potentiation) triggered a compensatory increase in a potassium channel current (K’ current) — as did activating the potassium channel (K+ current) using pulses of light in mice with brain circuitry genetically engineered to respond to it (optogenetic excessive activation). Credit: Ming-Hu Han, Ph.D., Icahn School of Medicine at Mount Sinai     Scientists have traced vulnerability to depression-like behaviors in mice to out-of-balance electrical activity inside neurons of the brain’s reward circuit and experimentally reversed it – but there’s a twist. … Read more

  • There’s something ancient in the icebox
    Glaciers are commonly thought to work like a belt sander. As they move over the land they scrape off everything — vegetation, soil, and even the top layer of bedrock. So scientists were greatly surprised to discover an ancient tundra landscape preserved under the Greenland Ice Sheet, below two miles of ice. “We found organic soil that has been frozen to the bottom of the ice sheet for 2.7 million years,” said University of Vermont geologist Paul Bierman — providing strong evidence that the Greenland Ice Sheet has persisted much longer than previously known, enduring through many past periods of global warming. … Read more

  • Archaeological, genetic evidence expands views of domestication
    One of the markers of domestication is a reduction in size, but archeological evidence indicates size decreases were slow and inconsistent. Donkeys buried 5,000 years ago in an early pharaonic mortuary complex (above) have proportions similar to those of the African wild ass, but the bones of domesticated donkeys found at another, much older site are significantly smaller than those of wild asses. Credit: Stine Rossel/PNAS Many of our ideas about domestication derive from Charles Darwin, whose ideas in turn were strongly influenced by British animal-breeding practices during the 19th century, a period when landowners vigorously pursued systematic livestock improvement. … Read more

Mathematicians in the US may have a jet-lag cure in the form a new app called Entrain. But does it work? Our circadian clock, which drives daily 24-hour rhythms in our physiology and behaviour, is to blame for jet lag. It cannot instantly reset to the destination time zone and the adjusting process can take a number of days. The rate at which our clocks reset depends upon a number of factors including the number of time zones crossed, the direction of travel (east or west) and the light exposure experienced before and upon arrival. … Read more
