Can your blood type affect your memory in later years? Posted: 10 Sep 2014 03:59 PM PDT People with blood type AB may be more likely to develop memory loss in later years than people with other blood types, according to a study. AB is the least common blood type, found in about 4 percent of the U.S. population. The study found that people with AB blood were 82 percent more likely to develop the thinking and memory problems that can lead to dementia than people with other blood types.

Electronics that need very little energy? Nanotechnology used to help cool electrons with no external sources Posted: 10 Sep 2014 10:25 AM PDT A team of researchers has discovered a way to cool electrons to minus 228 degrees Celsius without external means and at room temperature, an advancement that could enable electronic devices to function with very little energy.

Three extinct squirrel-like species discovered: Mammals may have originated much earlier than thought Posted: 10 Sep 2014 10:25 AM PDT Paleontologists have described three new small squirrel-like species that place a poorly understood Mesozoic group of animals firmly in the mammal family tree. The study supports the idea that mammals -- an extremely diverse group that includes egg-laying monotremes such as the platypus, marsupials such as the opossum, and placentals like humans and whales -- originated at least 208 million years ago in the late Triassic, much earlier than some previous research suggests.

Carbon dioxide concentration surges: Record greenhouse gas levels impact atmosphere and oceans, WMO report finds Posted: 09 Sep 2014 09:17 AM PDT The amount of greenhouse gases in the atmosphere reached a new record high in 2013, propelled by a surge in levels of carbon dioxide. This is according to the World Meteorological Organization's annual Greenhouse Gas Bulletin, which injected even greater urgency into the need for concerted international action against accelerating and potentially devastating climate change.

Nuclear waste eaters: Scientists discover hazardous waste-eating bacteria Posted: 09 Sep 2014 06:36 AM PDT Tiny single-cell organisms discovered living underground could help with the problem of nuclear waste disposal, say researchers. Although bacteria with waste-eating properties have been discovered in relatively pristine soils before, this is the first time that microbes that can survive in the very harsh conditions expected in radioactive waste disposal sites have been found.

Scientists take a look at the feel-good benefits of belly dance Posted: 08 Sep 2014 09:07 AM PDT A new study contributes to the scant literature available on belly dancing. Belly dancers have fewer hang-ups about their bodies. Most women who participate in this torso-driven dance do so because it is fun and they get to perform interesting moves -- not because they necessarily feel sexier while doing so.

Enigmatic Viking fortress discovered in Denmark Posted: 08 Sep 2014 06:36 AM PDT On fields at Vallø Estate, near Køge, researchers have discovered traces of a massive Viking fortress built with heavy timbers and earthen embankments. The perfectly circular fortress is similar to the famous so-called 'Trelleborg' fortresses, which were built by King Harald Bluetooth around AD 980.

Sleeping on animal fur in infancy found to reduce risk of asthma Posted: 08 Sep 2014 05:37 AM PDT Sleeping on animal fur in the first three months of life might reduce the risk of asthma in later childhood a new study has found. The chance of having asthma at the age of 6 years was 79% lower in children who had slept on animal skin after birth compared with those who were not exposed to animal skin. The risk decreased to 41% by the age of 10.
