| Short lives, violent deaths: Two CT-scanned Siberian mammoth calves yield trove of insights Posted: 13 Jul 2014 01:33 PM PDT CT scans of two newborn woolly mammoths recovered from the Siberian Arctic are revealing previously inaccessible details about the early development of prehistoric pachyderms. In addition, the X-ray images show that both creatures died from suffocation after inhaling mud. |
| Smell and eye tests show potential to detect Alzheimer's early Posted: 13 Jul 2014 12:55 PM PDT A decreased ability to identify odors might indicate the development of cognitive impairment and Alzheimer's disease, while examinations of the eye could indicate the build-up of beta-amyloid, a protein associated with Alzheimer's, in the brain, according to the results of four new research trials. |
| Australia drying caused by greenhouse gases, study shows Posted: 13 Jul 2014 12:55 PM PDT A new high-resolution climate model has been developed that shows southwestern Australia's long-term decline in fall and winter rainfall is caused by increases in human-made greenhouse gas emissions and ozone depletion, according to research. Several natural causes were tested with the model, including volcano eruptions and changes in the sun's radiation. But none of these natural climate drivers reproduced the long-term observed drying, indicating this trend is due to human activity. |
| Deep within spinach leaves, vibrations enhance efficiency of photosynthesis Posted: 13 Jul 2014 12:55 PM PDT Biophysics researchers have used short pulses of light to peer into the mechanics of photosynthesis and illuminate the role that molecule vibrations play in the energy conversion process that powers life on our planet. |
| Does this trunk make me look fat? Overweight zoo elephants no laughing matter Posted: 13 Jul 2014 12:53 PM PDT The birthrate for African elephants in zoos is declining, and researchers look for a link between inflammation and obesity that may be connected to the increase in infertility. "Obesity affects about 40 percent of African elephants in captivity," said one researcher. "Much as we see in humans, excess fat in elephants contributes to the development of heart disease, arthritis, a shorter lifespan and infertility." |
| Posted: 11 Jul 2014 10:28 AM PDT Last year, researchers discovered that when water droplets spontaneously jump away from superhydrophobic surfaces during condensation, they can gain electric charge in the process. Now, the same team has demonstrated that this process can generate small amounts of electricity that might be used to power electronic devices. |
| Technology developed to redirect proteins towards specific areas of genome Posted: 10 Jul 2014 11:16 AM PDT A research group has managed to reprogram the binding of a protein called BuD to DNA in order to redirect it towards specific DNA regions. The lead researcher says the discovery "will allow us to modify and edit the instructions contained in the genome to treat genetic diseases or to develop genetically-modified organisms." |
