New clues suggest wet era on early Mars was global (June 26, 2010) -- Minerals in northern Mars craters seen by two orbiters suggest that a phase in Mars' early history with conditions favorable to life occurred globally, not just in the south. ... > full story
Mechanism that may trigger degenerative disease identified (June 26, 2010) -- A mechanism that regulates stem-cell differentiation in mice testes suggests a similar process that may trigger degenerative disease in humans, according to a reproductive physiologist. ... > full story
Chemists find an easier way to synthesize new drug candidates; New method could have a big impact on pharmaceutical business (June 26, 2010) -- Chemists have designed a new way to attach a trifluoromethyl group to certain compounds, which they believe could allow pharmaceutical companies to create and test new drugs much faster and potentially reduce the cost of drug discovery. The new synthesis could have an immediate impact. ... > full story
Novel radiotracer shines new light on the brains of Alzheimer's disease patients (June 26, 2010) -- A trial of a novel radioactive compound readily and safely distinguished the brains of Alzheimer's disease patients from healthy volunteers on brain scans and opens the doors to making such imaging available beyond facilities that can manufacture their own radioactive compounds. ... > full story
Climate change complicates plant diseases of the future (June 26, 2010) -- Human-driven changes in the earth's atmospheric composition are likely to alter plant diseases of the future. Researchers are studying the impact of elevated carbon dioxide, elevated ozone and higher atmospheric temperatures on plant diseases that could challenge crops in these changing conditions. ... > full story
Pleasing to the eye: Even brooding female birds are sensitive to visual stimulation (June 26, 2010) -- In a breeding experiment with Houbara bustards -- a North African bird species with a very distinctive courtship behavior -- scientists have concluded that visual stimulation from attractive males of the same species positively affects brooding females, improving offspring growth. ... > full story
Scientists create 3-D models of whole mouse organs (June 26, 2010) -- Engineers have for the first time created 3-D models of whole intact mouse organs, a feat they accomplished using fluorescence microscopy. ... > full story
Ingredient in red wine may prevent some blinding diseases (June 26, 2010) -- Resveratrol -- found in red wine, grapes, blueberries, peanuts and other plants -- stops out-of-control blood vessel growth in the eye, according to vision researchers. The discovery has implications for preserving vision in blinding eye diseases such as diabetic retinopathy and age-related macular degeneration, the leading cause of blindness in Americans over 50. ... > full story
Gene therapy a step closer to mass production (June 26, 2010) -- Researchers in Latvia and Finland have synthesized and studied a range of organic compounds able to carry genetic material into individual cells where it can remedy the diseases caused by defective genes. Still under development, these compounds are much more readily produced than the viral carriers now in use and avoid their side-effects. Most importantly, they are much more effective than other organic carrier substances developed so far. ... > full story
Detecting eye injury (June 26, 2010) -- Scientists have developed a noninvasive imaging technique to detect early stages of eye disease. ... > full story
Aggressive action to reduce soot emissions needed to meet climate change goals, experts say (June 26, 2010) -- Without aggressive action to reduce soot emissions, the time table for carbon dioxide emission reductions may need to be significantly accelerated in order to achieve international climate policy goals such as those set forth in last December's Copenhagen Accord, according to a new study. ... > full story
Study identifies couples’ underlying concerns during a fight (June 26, 2010) -- A new study has found that there are two fundamental underlying concerns when partners in a committed relationship fight. Researchers have identified the first type of underlying concern as perceived threat, which involves a perception that one's partner is being hostile, critical, blaming or controlling. The second type of concern is called perceived neglect, which involves a perception that one's partner is failing to make a desired contribution or failing to demonstrate an ideal level of commitment or investment in the relationship. ... > full story
