Desert dust alters ecology of Colorado alpine meadows
— 30 Jun 2009 | EnvironmentAccelerated snowmelt - precipitated by desert dust blowing into the mountains - changes how alpine plants respond to seasonal climate cues that regulate their life cycles, according to results of a new study reported this week in the journal Proceedings of the National Academy of Sciences (PNAS). These results indicate that global warming may have a greater influence on plants' annual growth cycles than previously thought…
From human bite to robot jaws
— 30 Jun 2009 | TechnologyThe UK spends around GBP2.5 billion each year on dental materials to replace or strengthen teeth. The Chewing Robot is a new biologically inspired way to test dental materials and it will be shown to the public for the first time at this year's Royal Society Summer Science Exhibition [30 June to 4 July]…
Early heart attack therapy with bone marrow extract improves cardiac function
— 30 Jun 2009 | HealthA UCSF study for the treatment of heart failure after heart attack found that the extract derived from bone marrow cells is as effective as therapy using bone marrow stem cells for improving cardiac function, decreasing the formation of scar tissue and improving cardiac pumping capacity after heart attack…
Toxic chemicals affect steroid hormones differently in humans and invertebrates
— 30 Jun 2009 | EnvironmentIn a study with important consequences for studies on the effects of chemicals on steroid responses in humans, a team of French and American scientists, including Michael E. Baker, PhD, professor in UC San Diego's Department of Medicine, Division of Nephrology-Hypertension, have found that - contrary to earlier assumptions - enzymes used for the synthesis of steroids in insects, snails, octopuses and corals are unrelated to those used in humans…
