| Was human evolution caused by climate change? Posted: 15 Mar 2012 12:25 PM PDT Models of how animal and plant distributions are affected by climate change may also explain aspects of human evolution. |
| Sex-deprived fruit flies turn to alcohol, perhaps to fulfill a physiological demand for a reward Posted: 15 Mar 2012 11:54 AM PDT After being deprived of sex, male fruit flies may turn to alcohol to fulfill a physiological demand for a reward, according to a new study. Neurobiology experts say that understanding why rejected male flies find solace in ethanol could help treat human addictions. |
| With climate change, US could face risk from Chagas disease Posted: 15 Mar 2012 11:02 AM PDT People in the US may be at higher risk for Chagas disease than previously understood. A new study finds that 38 percent of kissing bugs collected in Arizona and California contained human blood and that more than 50 percent of the bugs also carried the parasite that causes this life-threatening disease. This upends the view that US kissing bug species don't regularly feed on people and suggests that Chagas could spread, driven north by climate change. |
| Protein researchers unravel the molecular dance of DNA repair Posted: 15 Mar 2012 09:30 AM PDT Using state-of-the-art technology, scientists have successfully obtained "molecular snapshots" of tens of thousands processes involved in DNA damage repair. The results will help unravel exactly how cells repair their broken DNA, how chemotherapy affects cells' workings and will assist in the discovery of new drugs with fewer side effects. |
| Posted: 15 Mar 2012 09:30 AM PDT Researchers have reached an unprecedented analysis in the field of personalized medicine. Their findings rely on collecting and analyzing billions of individual bits of data, an integrative Personal "Omics" Profile, or iPOP. "Omics" indicates the study of a body of information, such as the genome or the proteome. The iPOP can identify and predict myriad problems including diabetes, and researchers say that such dynamic monitoring will soon become commonplace. |
| Researcher watches the start of his own disease with unprecedented detail Posted: 15 Mar 2012 09:30 AM PDT These days, most of us don't head to the doctor until we are already ill. What if you could see disease approaching just as it starts to head your way? A new study focused on human biology shows that this futuristic notion is already in reach. |
| Cell phone use in pregnancy may cause behavioral disorders in offspring, mouse study suggests Posted: 15 Mar 2012 08:01 AM PDT Exposure to radiation from cell phones during pregnancy affects the brain development of offspring, potentially leading to hyperactivity, researchers have determined. |
| Cheaper drugs and better health care with a single chip Posted: 15 Mar 2012 06:58 AM PDT A researcher is developing technologies to miniaturize the first phase of a process used by pharmaceutical companies to discover new drugs. A breakthrough could ultimately lead to personalized and therefore more effective medical treatments, as well as major health care savings. |
| Dietary cadmium may be linked with breast cancer risk Posted: 15 Mar 2012 06:45 AM PDT Dietary cadmium, a toxic metal widely dispersed in the environment and found in many farm fertilizers, may lead to an increased risk of breast cancer, according to a new study. Cadmium occurs at low concentrations naturally, but scientists are concerned because contamination of farmland mainly due to atmospheric deposition and use of fertilizers leads to higher uptake in plants. Consuming whole grains and vegetables may counteract the effects. |
