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.

Super-elastic alloy is first known metal to get springier as it heats up

City University of Hong Kong researchers have accidentally discovered a first-of-its-kind alloy that retains its stiffness instead of softening as the temperature rises. Indeed, high-entropy Elinvar appears to get stiffer and springier as temperatures approach 1,000 K (727°C, 1,341 °F). No other known metals have been found to behave this way.

In addition to the Elinvar effect, this metal also displays an elastic limit of about 2 percent at room temperature. You can see the extraordinary spring-back power of this high-entropy Elinvar alloy demonstrated in a room-temperature ball bearing drop test in the video.

Around 450 BCE, Anaxagoras of Clazomenae had some time to think. The Greek mathematician was in prison for claiming the sun was not a god, but rather an incandescent rock as big as the Peloponnese peninsula. A philosopher who believed that “reason rules the world,” he used his incarceration to grapple with a now-famous math problem known as squaring the circle: Using a compass and a straightedge, can you produce a square of equal area to a given circle?

Surprisingly, mathematicians are still working on this question. And they’re making headway. A paper posted online last week by Andras Máthé and Oleg Pikhurko of the University of Warwick and Jonathan Noel of the University of Victoria is the latest to join in this ancient tradition.
