| First animals oxygenated Earth's oceans, study suggests Posted: 09 Mar 2014 12:05 PM PDT The evolution of the first animals may have oxygenated Earth's oceans -- contrary to the traditional view that a rise in oxygen triggered their development. New research contests the long held belief that oxygenation of the atmosphere and oceans was a pre-requisite for the evolution of complex life forms. The study builds on the recent work of scientists in Denmark who found that sponges -- the first animals to evolve -- require only small amounts of oxygen.  |
| Four new human-made ozone depleting gases found in the atmosphere Posted: 09 Mar 2014 12:05 PM PDT Scientists at the University of East Anglia have identified four new human-made gases in the atmosphere -- all of which are contributing to the destruction of the ozone layer. New research reveals that more than 74,000 tonnes of three new chlorofluorocarbons (CFCs) and one new hydrochlorofluorocarbon (HCFC) have been released into the atmosphere.  |
| Blood test identifies those at-risk for cognitive decline, Alzheimer's within three years Posted: 09 Mar 2014 12:05 PM PDT A blood test that can predict with greater than 90 percent accuracy if a healthy person will develop mild cognitive impairment or Alzheimer's disease within three years has been discovered and validated.  |
| Some people really just don't like music Posted: 06 Mar 2014 10:04 AM PST It is often said that music is a universal language. However, a new report finds that music doesn't speak to everyone. There are people who are perfectly able to experience pleasure in other ways who simply don't get music in the way the rest of us do.  |
| Higher levels of omega-3 in diet are associated with better sleep, study shows Posted: 06 Mar 2014 07:39 AM PST Higher levels of omega-3 DHA, the group of long-chain fatty acids found in algae and seafood, are associated with better sleep, shows a randomized, placebo-controlled study. The study finds that higher blood levels of the long-chain omega-3 DHA (the main omega-3 fatty acid found in the brain) are significantly associated with better sleep, including less bedtime resistance, parasomnias and total sleep disturbance. It adds that higher ratios of DHA in relation to the long-chain omega-6 fatty acid AA (arachidonic acid) are also associated with fewer sleep problems.  |
| Alzheimer's disease much larger cause of death than reported, study shows Posted: 05 Mar 2014 04:12 PM PST Alzheimer's disease may contribute to close to as many deaths in the United States as heart disease or cancer, a new study suggests. Currently, Alzheimer's disease falls sixth on the list of leading causes of death in the United States according to the Centers for Disease Control and Prevention (CDC), whereas heart disease and cancer are numbers one and two, respectively. These numbers are based on what is reported on death certificates.  |
| Transparent, color solar cells fuse energy, beauty Posted: 04 Mar 2014 10:00 AM PST Colorful, see-through solar cells could one day be used to make stained-glass windows, decorations and even shades that turn the sun's energy into electricity.  |
| Physics in 3-D? That's nothing: Try 0-D Posted: 04 Mar 2014 09:58 AM PST Zero-dimensional quantum dots could someday have a big effect on a variety of technologies, such as solar energy, lasers and medical diagnostics. This latest discovery is all about going small, but its significance is anything but. The research team's ability to control the confinement energy by varying the size of the quantum dot opens up a world of possibilities.  |
| Cell therapy shows remarkable ability to eradicate cancer in clinical study Posted: 19 Feb 2014 11:25 AM PST The largest clinical study ever conducted to date of patients with advanced leukemia found that 88 percent achieved complete remissions after being treated with genetically modified versions of their own immune cells. "These extraordinary results demonstrate that cell therapy is a powerful treatment for patients who have exhausted all conventional therapies," said a senior author. "Our initial findings have held up in a larger cohort of patients, and we are already looking at new clinical studies to advance this novel therapeutic approach in fighting cancer."  |
