It looks like “food from air”

Kent Taylor, the co-founder and CEO of Texas Roadhouse Inc., has died from suicide, his family said, after suffering “unbearable” COVID-19-related symptoms.

Taylor’s family and the restaurant chain said in a statement to The Hill on Sunday that the business executive “took his own life this week” after “a battle with post-Covid related symptoms, including severe tinnitus.”

“Kent battled and fought hard like the former track champion that he was, but the suffering that greatly intensified in recent days became unbearable,” the statement read.

Airspeeder wants to be the “first electric flying car race,” its CEO told Insider. It also wants you to know flying cars are closer than you think.

The sudden prevalence of an artery in the forearm is evidence that we’re still very much a work in progress.

NASA systems engineer Dr. Farah Alibay from JPL talks about the Ingenuity helicopter and how it will separate from the Perseverance rover and then land on the Red Planet.

Here’s my latest video!

In November 2020, I made a HDL video based on a meta-analysis in ~3.4 million subjects that was published in July 2020. In Dec 2020, a larger study (n=15.8 million subjects) was published-those data are presented in the video, and compared against the meta-analysis.

Devices shift away from Robocop-like wearables to simpler, more accessible assistive solutions.

There are many, many wearable and portable devices aimed at improving life for the blind and visually impaired (in some cases, even restoring vision). Such devices have been developed for pretty much every part of the body: fingers, wrists, abdomen, chest, face, ears, feet, even the tongue.

Albert Einstein’s special theory of relativity famously dictates that no known object can travel faster than the speed of light in vacuum, which is 299792 km/s. This speed limit makes it unlikely that humans will ever be able to send spacecraft to explore beyond our local area of the Milky Way.

However, new research by Erik Lentz at the University of Göttingen suggests a way beyond this limit. The catch is that his scheme requires vast amounts of energy and it may not be able to propel a spacecraft.

Lentz proposes that conventional energy sources could be capable of arranging the structure of spacetime in the form of a soliton – a robust singular wave. This soliton would act like a “warp bubble’”, contracting space in front of it and expanding space behind. Unlike objects within spacetime, spacetime itself can bend, expand or warp at any speed. Therefore, a spacecraft contained in a hyper-fast bubble could arrive at its destination faster than light would in normal space without breaking any physical laws, even Einstein’s cosmic speed limit.
