Reforestation projects capture more carbon than industrial plantations, new research reveals - Australian scientists researching environmental restoration projects have found that the reforestation of damaged rainforests is more efficient at capturing carbon than controversial softwood monoculture plantations. The research challenges traditional views on the efficiency of industrial monoculture plantations.... Tools that assess bias in standardized tests are flawed, study finds - Overturning more than 40 years of accepted practice, new research proves that the tools used to check tests of "general mental ability" for bias are themselves flawed. This key finding challenges reliance on such exams to make objective decisions for employment or academic admissions even in the face of well-documented gaps between mean scores of white and minority populations.... Regenerating damaged tissues: Bioscaffolds promote growth of joints in rabbits - A team of researchers has successfully regenerated rabbit joints using a cutting-edge process to form the joint inside the body, or in vivo. Regenerative in vivo procedures are performed by stimulating previously irreparable organs or tissues to heal themselves. In this study, bioscaffolds, or three-dimensional structures made of biocompatible and biodegradable materials in the shape of the tissue, were infused with a protein to promote growth of the rabbit joint.... Unexpected viral 'fossils' found in vertebrate genomes - Over millions of years, retroviruses, which insert their genetic material into the host genome as part of their replication, have left behind bits of their genetic material in vertebrate genomes. In a recent study, a team of researchers found that human and other vertebrate genomes also contain many ancient sequences from Ebola/Marburgviruses and Bornaviruses -- two deadly virus families.... Plant compound resveratrol shown to suppresses inflammation, free radicals in humans - Resveratrol, a popular plant extract shown to prolong life in yeast and lower animals due to its anti-inflammatory and antioxidant properties, appears also to suppress inflammation in humans, based on results from the first prospective human trial of the extract....

Researchers find new translocation; weak spots in DNA lead to genetic disease - Pediatric researchers continue to discover recurrent translocations -- places in which two chromosomes exchange pieces of themselves, and can lead to genetic disease and disability. Originating in locations where DNA strands are prone to bending and breaking, this translocation between chromosomes 8 and 22 strengthens the possibility that unstable spots in the genome may reflect a general mechanism lurking in the structure of DNA.... How not to blow up a molecule - Can single-shot imaging with femtosecond x-ray pulses from powerful new free electron lasers really work, or will the beam damage the sample too quickly? Pulse length is the key. A new study reveals that "frustrated absorption" explains why ultrashort pulses, even if their peak power is greater, do less damage to molecules than longer pulses.... Brain potentials reveal spectator effect - The neurological responses caused by observing somebody else playing a game have been uncovered. Researchers found differing responses for neutral observers, compared to those who wished the player to fail and those who wanted to see the player succeed.... Rocks on Mars may provide link to evidence of living organisms roughly 4 billion years ago - A new paper reveals groundbreaking research on the hydrothermal formation of Clay-Carbonate rocks in the Nili Fossae region of Mars. The findings may provide a link to evidence of living organisms on Mars, roughly 4 billion years ago in the Noachian period.... Calcium supplements linked to increased risk of heart attack, study finds - Calcium supplements, commonly taken by older people for osteoporosis, are associated with an increased risk of a heart attack, a new study finds.... Audubon's first engraving of a bird discovered - In 1824, John James Audubon (1785-1851), the eminent American artist, created a drawing of a running grouse for use in the design for a New Jersey bank note. Although the artist mentions the drawing and the resulting engraved paper money in two separate diary entries, no one has ever been able to locate or identify such an illustration. Until now.... Resting brain activity associated with spontaneous fibromyalgia pain - A recent study provides the first direct evidence of linkage between elevated intrinsic (resting-state) brain connectivity and spontaneous pain intensity in patients with fibromyalgia. This research shows an interaction of multiple brain networks, offering greater understanding of how pain arises....

Psychologists develop two potent new predictors of suicide risk - Two powerful new tests developed by psychologists show great promise in predicting patients' risk of attempting suicide. The work may help clinicians overcome their reliance on self-reporting by at-risk individuals, information that often proves misleading when suicidal patients wish to hide their intentions.... Some trees 'farm' bacteria to help supply nutrients - Some trees growing in nutrient-poor forest soil may get what they need by cultivating specific root microbes to create compounds they require. These microbes are exceptionally efficient at turning inorganic minerals into nutrients that the trees can use.... Key enzyme in DNA repair pathway identified - Researchers have discovered an enzyme crucial to a type of DNA repair that also causes resistance to a class of cancer drugs most commonly used against ovarian cancer.... Best hope for saving Arctic sea ice is cutting soot emissions, say researchers - Soot from the burning of fossil fuels and solid biofuels contributes far more to global warming than has been thought, according to a new study. But, unlike carbon dioxide, soot lingers only a few weeks in the atmosphere, so cutting emissions could have a significant and rapid impact on the climate. Controlling it may be the only option for saving the Arctic sea ice before it all melts.... Kidney injury prevention may be possible: Watch for the warning signs - Reduced kidney function and protein in the urine place a person at risk for kidney injury, according to a new study. The results suggest that improved recognition of these warning signs could help reduce preventable forms of acute kidney injury.... Researchers study benefits of white button mushrooms - Scientists have conducted an animal-model and cell-culture study showing that white button mushrooms enhanced the activity of critical cells in the body's immune system.... Migrating birds can?t control themselves - During the spring and fall migratory seasons, sparrows become significantly less capable of resisting temptation. Researchers investigated impulse control and sleep in white-crowned sparrows during migratory and non-migratory seasons. During migratory periods, the birds slept very little and became more impulsive, but sleep loss itself was not entirely to blame for their impulsivity.... Graphene exhibits bizarre new behavior well suited to electronic devices - Graphene, a sheet of pure carbon, has been touted as a possible replacement for silicon-based semiconductors because of its useful electronic properties. Now, physicists have shown that graphene has another unique and amazing property that could make it even more suitable for future electronic devices.
