Physicists Observe Branched Flow of Light

Posted by in categories: entertainment, physics

Physicists from the Technion-Israel Institute of Technology and the University of Central Florida have experimentally observed optical branched flow in liquid soap films.

Instead of producing completely random speckle patterns, the slowly varying disordered potential gives rise to focused filaments that divide to form a pattern resembling the branches of a tree.

Researchers Indicate COVID-19 Mutation Has Made Virus More Contagious

Posted by in categories: biotech/medical, genetics

Researchers from Northwest University’s medical school in Chicago believe a mutation in the coronavirus has made it considerably more contagious.

Infection disease special Egon Ozer of the Feinberg School of Medicine has said that upon examining the genetic structure of coronavirus samples, it was evident there was a change in one of the amino acids that allowed a spike in protein on the surface of the virus.

In layman’s terms, this change has allowed the virus to penetrate nearby cells easier, and as a result the virus can replicate faster and be passed on easier.

Age-related heart disease linked to gut bacteria metabolite

Posted by in categories: biotech/medical, chemistry, food, life extension

New research from the University of Colorado Boulder has offered some of the clearest evidence to date showing how the gut microbiome produces a metabolite that, over time, contributes to age-related declines in cardiovascular health.

High blood levels of trimethylamine-N-Oxide (TMAO), a metabolic byproduct of digestion, have been strongly linked to negative cardiovascular health. When one eats red meat, eggs or other animal proteins, certain types of gut bacteria feed on chemicals in those foods and produce TMA, or trimethylamine, which is then turned into TMAO in the liver.

A number of studies have linked TMAO to heart disease, however, until now it hasn’t been clear exactly how this metabolite causes cardiovascular damage. A robust new study, published in the journal Hypertension, is offering one of the first thorough mechanistic investigations illustrating how TMAO damages the cardiovascular system.

Rare brain-eating amoeba infection confirmed in Florida, health officials say

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

A person in Florida has been infected with a rare and usually deadly brain-eating amoeba, according to health officials.

The Florida Department of Health announced Friday that one patient in Hillsborough County has been infected with Naegleria fowleri, a water-borne, microscopic single-celled amoeba that attacks the brain.

“Infections can happen when contaminated water enters the body through the nose,” the health department said.

Tesla’s $20,000 Compact Car — Coming Soon After Tesla Battery Day Reveals New Batteries

Posted by in categories: Elon Musk, media & arts, sustainability, transportation

Tesla is working on a compact car that will be manufactured in China and distributed worldwide. The battery technologies required for a compact car will be unveiled at Tesla Battery Day that will enable Tesla to make a small car for less than $25,000, possibly close to $20,000 or less. The battery cost is the main factor to drive down the cost of an electric vehicle. The compact car is coming soon after Tesla Battery Day technologies are revealed. The new batteries will allow Tesla to shrink the battery pack’s size while offering enough range for everyday driving. Elon Musk’s speech at the launch event in China suggests the car will be quite unique, just like the Cybertruck.

Luke Aikins No Parachute 25,000 Feet Airplane Jump Complete Video

Posted by in category: transportation

Stride Gum Presents Heaven Sent
Luke Aikins, the first person to accomplish a planned jump out of an airplane without a parachute or wing suit from a very high altitude (25,000 feet) (7,620 meters). Aikins eventually lands in a net.

“Jumpers are away. Now he’s practicing the flip. That’s how he’ll have to land. He’ll have to land on his back. At 18,000 feet the oxygen mask will come off. There goes the oxygen mask. Now at 12,000 feet he’ll hear a beep in his helmet that will tell him he’s halfway home.”
