Dogs that make so-called puppy eyes at their owners get a spike in the “love hormone” oxytocin — and their owners do too, according to a new study. This same positive feedback in oxytocin release occurs when a mom gazes at her newborn infant, studies have shown.
A Duke University study involving lab mice suggests there’s a link between Alzheimer’s disease and a faulty immune system. The study suggests that certain immune cells that normally protect the brain begin to abnormally consume an important amino acid: arginine.
Characteristics passed between generations are not decided solely by DNA, but can be brought about by other material in cells, new research shows. Scientists studied proteins found in cells, known as histones, which are not part of the genetic code, but act as spools around which DNA is wound. Histones are known to control whether or not genes are switched on.
NASA chief scientist Ellen Stofan said on Tuesday that, within a decade, humanity will have found ‘strong indications’ of alien life. “I think we’re going to have strong indications of life beyond Earth within a decade, and I think we’re going to have definitive evidence within 20 to 30 years,” NASA chief scientist Ellen Stofan said Tuesday (April 7).
Researchers from the University of California, Berkeley, set out to discover exactly that when they tracked emotions such as compassion, joy, love, and so on versus the levels of interleukin-6 (IL-6)—a secretion which causes inflammation in the body—in the saliva of 119 university students. The researchers found that those who regularly have positive emotions have less IL-6—and they noticed the strongest correlation with one particular emotion: awe.
On Saturday morning, April 4, 2015 not long before sunrise, the bright full moon over North America turned a lovely shade of celestial red during a total lunar eclipse. This stunning video captures the entire celestial event.
This Saturday, you’ll be able to witness a total lunar eclipse if you live in western North America, eastern Asia, the Pacific, Australia or New Zealand. The astronomical happening will be “the shortest total lunar eclipse of the 21st century” according to EarthSky.org
This could mean good things for people with Alzheimer’s disease.
For more than 50 years, scientists had clues suggesting that a tiny songbird known as the blackpoll warbler fly’s nonstop over the Atlantic Ocean, but proof was hard to come by. Now, an international team of biologists report “irrefutable evidence” that the birds complete a nonstop flight ranging from about 1,410 to 1,721 miles (2,270 to 2,770 km) in just two to three days.
