Dramatic ocean circulation changes caused a colder Europe in the past (January 15, 2011) -- The unusually cold weather in Europe this winter has been caused by a change in the winds. Instead of the typical westerly winds warmed by Atlantic surface ocean currents, cold northerly Arctic winds are influencing much of Europe. However, scientists have long suspected that far more severe and longer-lasting cold intervals have been caused by changes to the circulation of the warm Atlantic ocean currents themselves. ... > full story
Why coffee protects against diabetes (January 15, 2011) -- Researchers have discovered a possible molecular mechanism behind coffee's protective effect against type 2 diabetes. ... > full story
Bioactive compounds in berries can reduce high blood pressure (January 15, 2011) -- Eating blueberries can guard against high blood pressure, according to new research. ... > full story
Skin provides Australia's first adult stem cells for rare genetic disease (January 15, 2011) -- Scientists have developed Australia's first adult induced pluripotent stem cell lines using skin biopsies from patients with the rare genetic disease Friedreich's ataxia. ... > full story
Laser sheds light on tracking source of microbial contamination on beach (January 15, 2011) -- A simple, automated method of tracking E. coli uses a laser to detect and monitor the microbe in potentially contaminated bodies of water or waterways. The technique could reduce the incidence of waterborne disease outbreaks. ... > full story
Universities miss chance to identify depressed students, study finds (January 15, 2011) -- One out of every four or five students who visits a university health center for a routine cold turns out to be depressed, but most centers miss the opportunity to identify these students because they don't screen for depression, according to new research. About 2 to 3 percent of these depressed students have had suicidal thoughts or are considering suicide. Depression screening is easy and must be done for every health center student, researchers said. ... > full story
Self-assembling structures open door to new class of materials (January 15, 2011) -- Researchers have demonstrated bio-inspired structures that self-assemble from simple building blocks: spheres. The helical "supermolecules" are made of tiny colloid balls instead of atoms or molecules. Similar methods could be used to make new materials with the functionality of complex colloidal molecules. ... > full story
Tinnitus is the result of the brain trying, but failing, to repair itself (January 15, 2011) -- Tinnitus appears to be produced by an unfortunate confluence of structural and functional changes in the brain, say neuroscientists. ... > full story
Improving plants: New software quantifies leaf venation networks, enables plant biology advances (January 15, 2011) -- Plant biologists are facing pressure to breed plants that can respond to changing environments. One method of monitoring the response of plants to different environments is by studying their vein network patterns. To help address the challenge of how to quickly examine a large quantity of leaves, researchers have developed a user-assisted software tool that extracts macroscopic vein structures directly from leaf images. ... > full story
Cancer survivors likely to experience pain at some point in care (January 15, 2011) -- More than 40 percent of cancer survivors experience cancer pain since their diagnosis and many have current cancer-related chronic pain, according to new research. The study provides new insight on issues facing the growing number of US cancer survivors. ... > full story
New farming method reduces greenhouse gases, increases farm yields (January 15, 2011) -- Researchers have found methods to help farmers reduce nitrous oxide emissions while also increasing corn grain production. ... > full story
Academics urge universities to change culture to value teaching as highly as research (January 15, 2011) -- The reward systems at universities heavily favor science, math and engineering research at the expense of teaching, which can and must change, according to a group of academics. ... > full story
