Food is big business.

In the U.S., the weight-loss industry is worth $78 billion.

Meat is worth $218 billion.

Sugar processing is worth $11 billion.

Soybeans are worth $65 billion.

As a point of comparison, the U.S. cigarette industry is worth about $50 billion.

We are kidding ourselves if we think that corporate interests have no effect on nutrition research. For example, Coca-Cola spent “$132.8 million on scientific research and partnerships over a five-year period” from 2010 to 2015 as a part of a campaign to absolve sweetened beverages of contributing to America’s obesity epidemic. (And it worked.)

On April 10, 2021 NASA announced Ingenuity Mars Helicopter failed high-speed spin test causing reschedule of the first flight to no earlier than April 14. NASA explained that during a high-speed spin test of the rotors on Friday, the command sequence controlling the test ended early due to a “watchdog” timer expiration. This occurred as it was trying to transition the flight computer from ‘Pre-Flight’ to ‘Flight’ mode. The helicopter is safe and healthy and communicated its full telemetry set to Earth. The watchdog timer oversees the command sequence and alerts the system to any potential issues. It helps the system stay safe by not proceeding if an issue is observed and worked as planned. Ingenuity team is reviewing telemetry to diagnose and understand the issue. Following that, they will reschedule the full-speed test.

The film features Nick Bostrom, author of Superintelligence; Japanese roboticist, Hiroshi Ishiguro; Douglas Rushkoff, author of Team Human; Ben Goertzel, founder of Singularity.net; and Deepak Chopra, who is creating his own A.I. mind twin.

EXCLUSIVE: Here’s the first trailer for Hot Docs opener Artificial Immortality by filmmaker Ann Shin.

The documentary explores the latest advancements in AI, robotics and biotech with visionaries who argue for a new age of post-biological life. It poses the questions: if you were able to create an immortal version of yourself, would you?; and will AI be the best, or the last thing we ever do as a species?

Antisense oligonucleotide therapy works by altering the RNA, the messenger that carries instructions from your DNA to crank out proteins.

An article in Nature Reviews Neurology describes antisense oligonucleotides as “short, synthetic, single-strand” molecules, which can alter RNA to cause protein creation to be reduced, enhanced, or modified.

In the Penn study, the targeted protein was created by the mutated LCA gene.

Microsoft Corp. is in advanced talks to buy artificial intelligence and speech technology company Nuance Communications Inc., according to people familiar with the matter.

An agreement could be announced as soon as this week, said the people, who asked not to be identified because the information is private. The price being discussed could value Nuance at about $56 a share, though the terms could still change, one of the people said.

Circa 2014 essentially this could make endless computer chips from light.

Princeton researchers have managed to cause light to behave like a crystal within a specialized computer chip, according to a recent paper. This is the first time anyone has accomplished this effect in a lab.

Here’s why it’s so hard: Atoms can easily form solids, liquids, and gasses, because when they come into contact they push and pull on each other. That push and pull forms the underlying structure of all matter. Light particles, or photons, do not typically interact with one another, according to Dr. Andrew Houck, a professor of electrical engineering at Princeton and an author on the study. The trick of this research was forcing them to do just that.

“We build essentially an artificial atom, using lots of atoms acting in concert,” Houck tells Popular Science, “What emerges is a quantum mechanical object that [at about half a millimeter] is visible on the classical scale.”
