Sustained Cerebrovascular and Cognitive Benefits of Resveratrol in Postmenopausal Women

Posted by in categories: biotech/medical, life extension, neuroscience

Resveratrol may reduce aging within the brain.


Deficits in the cerebral microcirculation contribute to age-related cognitive decline. In a pilot study of postmenopausal women, we found that supplementation with a low dose of resveratrol, a phytoestrogen, for 14 weeks improved cerebrovascular and cognitive functions. We have since undertaken a larger, longer term study to confirm these benefits. Postmenopausal women aged 45–85 years (n = 129) were randomized to take placebo or 75 mg trans-resveratrol twice daily for 12 months. Effects on cognition, cerebral blood flow, cerebrovascular responsiveness (CVR) and cardiometabolic markers (blood pressure, diabetes markers and fasting lipids) were assessed. Compared to placebo, resveratrol improved overall cognitive performance (P < 0.001) and attenuated the decline in CVR to cognitive stimuli (P = The latter effect was associated with reduction of fasting blood glucose (r = P = This long-term study confirms that regular consumption of resveratrol can enhance cognitive and cerebrovascular functions in postmenopausal women, with the potential to slow cognitive decline due to ageing and menopause.

Coating That Could Destroy COVID-19 Virus, for Use in Hospital Masks, in Development

Posted by in categories: biotech/medical, health, nanotechnology

Researchers at the University of Central Florida (UCF) are working to create a protective coating that would include a new nanomaterial to catch #COVID19 and kill it within seconds.


ORLANDO, Fla., April 10, 2020 — The masks that health care workers wear to protect them from the virus that causes COVID-19 block the virus before it reaches their faces, but do not destroy it. To further protect doctors, nurses, and others on the front lines of the pandemic, researchers at the University of Central Florida (UCF) are working to create a protective coating that would include a new nanomaterial to catch the virus and kill it within seconds.

Scientists capture 3D images of nanoparticles, atom

Posted by in categories: nanotechnology, particle physics

O,.,o.


Since their invention in the 1930s, electron microscopes have helped scientists peer into the atomic structure of ordinary materials like steel, and even exotic graphene. But despite these advances, such imaging techniques cannot precisely map out the 3D atomic structure of materials in a liquid solution, such as a catalyst in a hydrogen fuel cell, or the electrolytes in your car’s battery.

Now, researchers at Berkeley Lab, in collaboration with the Institute for Basic Science in South Korea, Monash University in Australia, and UC Berkeley, have developed a technique that produces atomic-scale 3D images of nanoparticles tumbling in liquid between sheets of graphene, the thinnest material possible.

Meet Victor Vescovo, who just broke the world record by diving 35,853 feet into the deepest part of the ocean

Posted by in categories: business, education

Circa 2019


The world record for the deepest dive in history has just been broken by Dallas businessman and explorer Victor Vescovo, who plunged down 35,853ft into the Mariana Trench’s Challenger Deep—the deepest known point on Earth.

The depth achieved by Vescovo was 66 feet deeper than the previous record for a solo dive, held by film director James Cameron, who reached 35,787ft in 2012. The previous record for the world’s deepest dive (not solo) was 35,813ft, performed in 1960.

Charting a course toward quantum simulations of nuclear physics

Posted by in categories: computing, cosmology, particle physics, quantum physics, transportation

In nuclear physics, like much of science, detailed theories alone aren’t always enough to unlock solid predictions. There are often too many pieces, interacting in complex ways, for researchers to follow the logic of a theory through to its end. It’s one reason there are still so many mysteries in nature, including how the universe’s basic building blocks coalesce and form stars and galaxies. The same is true in high-energy experiments, in which particles like protons smash together at incredible speeds to create extreme conditions similar to those just after the Big Bang.

Fortunately, scientists can often wield simulations to cut through the intricacies. A represents the important aspects of one system—such as a plane, a town’s traffic flow or an atom—as part of another, more accessible system (like a or a scale model). Researchers have used their creativity to make simulations cheaper, quicker or easier to work with than the formidable subjects they investigate—like proton collisions or black holes.

Simulations go beyond a matter of convenience; they are essential for tackling cases that are both too difficult to directly observe in experiments and too complex for scientists to tease out every logical conclusion from basic principles. Diverse research breakthroughs—from modeling the complex interactions of the molecules behind life to predicting the experimental signatures that ultimately allowed the identification of the Higgs boson—have resulted from the ingenious use of simulations.
