NASA and the Canadian Space Agency have announced Phase 2 of the Deep Space Food Challenge with a video from the food world’s own scientist Alton Brown. The international contest is looking for “novel food production system technologies” for long-duration missions in space. A system that can supply, at minimum, a three-year round-trip  that will not have a resupply. NASA and the CSA have also want a system that uses “minimal inputs” while maximizing “safe, nutritious, and palatable food outputs.”
NASA will select ten US teams from the initial entrants to move on to the final on-site demonstration, with each team getting $20,000. As many as five from that group will then get $150,000 and an invitation to compete in Phase 3. US teams don’t need to be finalists to get a bonus reward either. NASA will also recognize five international teams as Phase 2 finalists. And the agency will declare as many as three as winners.
Registration for eligible teams will remain open until February 28, 2022.

Jeff Bezos Is Paying For a Way to Make Humans Immortal

He's backing a new biotech company working on "cellular rejuvenation programming."

The founder and former CEO of Amazon has reportedly made an investment in the freshly launched Altos Labs, a biotech startup focused on "cellular rejuvenation programming to restore cell health and resilience, with the goal of reversing disease to transform medicine," according to a January 19 press release. With $3 billion in backing on day one, Altos Labs has hit the ground running with what may be the single largest funding round for a biotech company, according to the Financial Times of London.
Altos Labs has an impressive roster of executives that includes experts formerly of GlaxoSmithKline, a health care company in the United Kingdom that primarily develops pharmaceuticals and vaccines; Genentech, a San Francisco-based biotech firm that created the first targeted antibody for cancer; and the National Cancer Institute.

Magnetic seeds can be steered into cancer tissue to kill it with heat

One promising possibility for next-gen cancer treatments involves infiltrating tumors with specially-designed particles and heating them up to destroy the cancerous tissue, and new research from the University of College London (UCL) takes this technology into new terrain. The team's solutions leverages MRI scanning to steer magnetic seeds to the site with a high level of precision, offering new hopes of advanced treatments for hard-to-reach cancers.

The technique at the heart of this research is known as magnetic hyperthermia, and it is a technology that has shown some exciting potential in recent years.

"Russia's Elon Musk" is developing hypersonic rocket cargo planes

Described by his PR team as "like Russia's Elon Musk," serial entrepreneur Mikhail Korkorich says his new company Destinus is building a hydrogen-powered, zero-emissions, transcontinental cargo drone capable of hypersonic Mach 15 cruise speeds.
This Hyperplane, according to Destinus, would "combine the technological advances of a spaceplane with the simple physics of a glider to create a vehicle that meets the demands of a hyper connected world," blasting cargo between Europe and Australia in just a couple of hours using clean liquid hydrogen fuel.

Read this deep dive about the invention and the complex political and military relationships surrounding it.

Biohybrid fish powered by beating human heart cells swims for 100 days

Researchers at Harvard and Emory University have created a biohybrid fish out of human heart muscle cells that can swim autonomously for months at a time as the cells beat. The project is a quirky sidestep on the way to eventually growing new functioning hearts for transplant.

This isn’t the first robot that this team has cobbled together out of heart cells. A few years ago they made a stingray out of heart cells from rats that could be steered with pulses of light. But for this new one, they upgraded to heart muscle cells derived from human stem cells, and created a fish robot that could swim around on its own.
