Stop Emitting Carbon Dioxide, Or Geoengineering Could Be Only Hope For Earth’s Climate, Experts Warn
The future of the Earth could rest on potentially dangerous and unproven geoengineering technologies unless emissions of carbon dioxide can be greatly reduced, the latest Royal Society report has found.
Scientists found the dose of DHA (docosahexaenoic acid) that is “just right” for preventing cardiovascular disease in healthy men. In a new study, they show that 200 mg of DHA per day is enough to affect biochemical markers that reliably predict cardiovascular problems. This study is the first to identify how much DHA is necessary [...]

Autism can build a wall of poor communication between those struggling with the condition and their families. While a personal computer can help bridge the divide, the distraction and complexity of a keyboard can be an insurmountable obstacle.
Viruses have numerous tricks for dodging the immune system. New research reveals a key detail in one of these stratagems, identifying a protein that enables cytomegalovirus to shut down an antiviral defense.

In an expedition for submerged evidence of early Americans off Florida’s Gulf Coast, archaeologists traced two ancient river systems in what they believe is the most extensive delineation of submerged prehistoric river systems ever done. They also identified chert, a stone used by prehistoric peoples in toolmaking, at three sites. Scientists believe they are on [...]
The risk of infant death following planned home birth attended by a registered midwife does not differ from that of a planned hospital birth, a Canadian study finds.
The ability to digest the milk sugar lactose first evolved in dairy farming communities in central Europe, not in more northern groups as was previously thought, finds a new study. The genetic change that enabled early Europeans to drink milk without getting sick has been mapped to dairying farmers who lived 7,500 years ago between [...]

Scientists in Singapore and Germany report that mutations in the PYCR1 gene cause the rare genetic condition that results in premature skin aging and that is known as “wrinkly skin syndrome.”
