Transgenic fungi may be able to combat malaria and other bug-borne diseases (February 26, 2011) -- New findings indicate that a genetically engineered fungus carrying genes for a human anti-malarial antibody or a scorpion anti-malarial toxin could be a highly effective, specific and environmentally friendly tool for combating malaria, at a time when the effectiveness of current pesticides against malaria mosquitoes is declining. ... > full story
Coral 'network' can protect Asia-Pacific fish stocks, study suggests (February 26, 2011) -- Researchers have established that the richest marine region on Earth -- the Coral Triangle between Indonesia, Malaysia and the Philippines -- depends vitally for its diversity and resilience on coral and fish larvae swept in from the South China Sea and Solomon Islands. ... > full story
Tweeting teenage songbirds reveal impact of social cues on learning (February 26, 2011) -- In a finding that once again displays the power of the female, neuroscientists have discovered that teenage male songbirds, still working to perfect their song, improve their performance in the presence of a female bird. ... > full story
Bamiyan Buddhas once glowed in red, white and blue (February 25, 2011) -- The monumental Buddhas of Bamiyan once shone in glowing colors. Restorers have analyzed hundreds of fragments of the statues that were blow up by the Taliban. They have, for the first time, been able to reliably date the period in which they were sculpted, and have also studied the technically brilliant method of construction. A new process could stabilize the porous rock, paving the way for a reconstruction. ... > full story
Rare, unique seeds arrive at Svalbard Vault, as crises threaten world crop collections (February 25, 2011) -- The Svalbard Global Seed Vault celebrated its third anniversary Feb. 24 with the arrival of seeds for rare lima beans, blight-resistant cantaloupe, and progenitors of antioxidant-rich red tomatoes from Peru and the Galapagos Islands. The arrival of these collections, including many drought- and flood-resistant varieties, comes at a time when natural and human-made risks to agriculture have reinforced the critical need to secure all the world's food crop varieties. ... > full story
Newborn heart muscle can grow back by itself, study shows (February 25, 2011) -- In a promising science-fiction-meets-real-world juxtaposition, researchers have discovered that the mammalian newborn heart can heal itself completely. ... > full story
Low vitamin D levels linked to allergies in kids (February 25, 2011) -- A study of more than 3,000 children shows that low vitamin D levels are associated with increased likelihood that children will develop allergies, according to a new article. ... > full story
HIV makes protein that may help virus's resurgence (February 25, 2011) -- New research enhances the current knowledge of how human immunodeficiency virus type-1 (HIV-1), which causes AIDS, controls the cell cycle of cells that it infects. The new findings may shed light on how the virus reactivates after entering a dormant state, called latency. Better understanding of the biological events that revive HIV from latency may eventually lead to better treatments for people with HIV infection. ... > full story
Much of Mississippi River sediment comes from stream bank collapse, rather than field runoff (February 25, 2011) -- Much of the Mississippi River's sediment load doesn't come from field runoff, according to work by scientists. Instead, researchers have confirmed that stream bank collapse and failure can be chief contributors to high sediment levels in the silty streams and rivers that flow into the Mississippi. ... > full story
Obesity and diabetes are a downside of human evolution, research suggests (February 25, 2011) -- As if the recent prediction that half of Americans will have diabetes or pre-diabetes by the year 2020 isn't alarming, a new genetic discovery provides a disturbing explanation as to why: we took an evolutionary "wrong turn." In the report, scientists show that human evolution leading to the loss of function in a gene called "CMAH" may make humans more prone to obesity and diabetes than other mammals. ... > full story
Links between longer ragweed season and climate change confirmed (February 25, 2011) -- New studies have confirmed what many pollen-sensitive people already suspected: In some parts of North America, ragweed season now lasts longer and ends later. ... > full story
New long-acting local anesthetic derived from algae effectively blocks pain in surgical patients (February 25, 2011) -- Medical researchers bringing surgical patients closer to having a long-acting local anesthetic. In a randomized, double-blind trial, patients given neosaxitoxin, a new local anesthetic derived from algae, had significantly less postoperative pain and recovered about two days sooner than those given the commonly used local anesthetic bupivacaine. ... > full story
