To commemorate the 50th anniversary of the Apollo 13 mission, a panoramic high-definition image of astronaut Fred Haise napping in the “lifeboat” Lunar Module has been produced.

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.

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.

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.

While billionaires vie for the stars, $750,000 trips to the bottom of the Marianas Trench will begin departing in May.
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.
Victor Vescovo wanted to be the first person to reach the deepest points of all five oceans – but first he had to build a submarine that was up to it.
