From a MedPageToday online article:
“Amyloid is important in initiating disease, but the actual damage in the brain is probably due to the accumulation of tau,” Holtzman told MedPage Today. “Normally, tau protein is inside cells, but there is more and more evidence suggesting that its spread to different parts of the brain is responsible for the progression of Alzheimer’s disease.”
Two studies in January explored how sleep might be associated with Alzheimer’s tau pathology. The first, led by Brendan Lucey, MD, and David Holtzman, MD, both of Washington University in St. Louis, found that older adults who had less slow-wave sleep had higher levels of brain tau.
The findings, published in Science Translational Medicine, suggested that poor quality sleep in late life may signal deteriorating brain health.
Sleep patterns predicted amyloid and tau burden, reported Matthew Walker, PhD, of the University of California Berkeley, and co-authors, in June.

The Fiat 8V (or “Otto Vu”) is a V8-engined sports car produced by the Italian car manufacturer Fiat from 1952 to 1954. The car was introduced at the 1952 Geneva Motor Show. The Fiat 8V got its name because at the time of its making, Fiat believed Ford had a copyright on “V8”. With 114 made, the 8V wasn’t a commercial success, but did well in racing. Apart from the differential the car did not share any parts with the other Fiats (but many parts were made by Siata and they used them for their cars). The 8V was developed by Dante Giacosa and the stylist Luigi Rapi. The engine was a V8 originally designed for a luxury sedan, but that project was stopped.
Listen to the latest from the world of science, brought to you by Benjamin Thompson and Nick Howe. This week, observations of objects orbiting a black hole, and rethinking how we measure screen-time.
“Our data showed that rates of accelerating blood pressure elevation were significantly higher in women than men, starting earlier in life,” said Cheng, the Erika J. Glazer Chair in Women’s Cardiovascular Health, who also serves as director of Cardiovascular Population Sciences at the Barbra Streisand Women’s Heart Center. “This means that if we define the hypertension threshold the exact same way, a 30-year old woman with high blood pressure is probably at higher risk for cardiovascular disease than a man with high blood pressure at the same age.”
January 13, 2020 – The prestigious Ocean Art Underwater Photo Competition, organized by the Underwater Photography Guide, has announced its 2019 winners. The 8th annual competition attracted an extremely high caliber of photos from oceans around the world. These photos showcase the best underwater photographs of the year. 2019 was one of the most competitive years to date. Our two new categories, conservation and blackwater diving, had an overwhelming response of incredible photos and were two of the highlights of the competition.
