It's bad enough to have to be tested for dementia. It's even worse if the test isn't fair. Researchers in Chicago found they needed to update the screening test for a type of early onset dementia so that the measure would more accurately pick up symptoms among a new wave of patients — baby boomers and Gen Xers.
"It's a very curious time in high-energy physics," says Michael Peskin, a researcher at SLAC National Accelerator Laboratory in California. On the one hand, researchers have just made the most significant discovery in decades: In July of last year, they announced they had found the Higgs particle at a collider in Switzerland. The Higgs is part of the mechanism that gives mass to everything. It is so fundamental that without it, we wouldn't exist.
A burst of brain activity just after the heart stops may be the cause of so-called near-death experiences, scientists say.
The insight comes from research involving nine lab rats whose brains were analyzed as they were being euthanized. Researchers discovered what appears to be a momentary increase in electrical activity in the brain associated with consciousness.
Although the experiment relied on animals, the results could apply to humans, too, the researchers say.
It's breathing, he thought. "All of a sudden I see a thing with a heartbeat."
John Nelson is a designer, well known for tracing complex weather patterns or cultural information on maps, so considering what he usually does, this was easy. NASA's Visible Earthteam publishes pictures of our planet every month of the year, so John thought, why not stitch them together, and see what the seasons look like from outer space?
