The design could someday enable a fully decarbonized power grid, researchers say.

Engineers at MIT and the National Renewable Energy Laboratory (NREL) have designed a heat engine with no moving parts. Their new demonstrations show that it converts heat to electricity with over 40 percent efficiency — a performance better than that of traditional steam turbines.

The heat engine is a thermophotovoltaic (TPV) cell, similar to a solar panel’s photovoltaic cells, that passively captures high-energy photons from a white-hot heat source and converts them into electricity. The team’s design can generate electricity from a heat source of between 1,900 to 2,400 degrees Celsius 0, or up to about 4,300 degrees Fahrenheit.

From self-replicating molecules in Archean seas, to eyeless fish in the Cambrian deep, to mammals scurrying from dinosaurs in the dark, and then, finally, improbably, ourselves – evolution shaped us.

Organisms reproduced imperfectly. Mistakes made when copying genes sometimes made them better fit to their environments, so those genes tended to get passed on. More reproduction followed, and more mistakes, the process repeating over billions of generations. Finally, Homo sapiens appeared. But we aren’t the end of that story. Evolution won’t stop with us, and we might even be evolving faster than ever.

It’s hard to predict the future. The world will probably change in ways we can’t imagine. But we can make educated guesses. Paradoxically, the best way to predict the future is probably looking back at the past, and assuming past trends will continue going forward. This suggests some surprising things about our future.

2022 is set to be a major year for the space economy. According to the Space Foundation, 15 new launch vehicles are set to debut this year, more than any other year in space history. Last year, US spaceports had more launches than any year since 1967, and the number is climbing. Meanwhile, employment in the core US space industry employment is at a 10-year high.

The momentum is there for a flourishing space economy that, according to NASA leaders, could in 20 years take public and private missions beyond low Earth orbit (LEO), with services and infrastructure on the lunar surface and in cislunar space. It’s a fast-growing economy, NASA leaders said at the 37th Space Symposium, that offers promising opportunities for young people who want to get their foot in the door.

The space economy is already a $400 billion industry “and on the way to $1 trillion, and I suspect it’ll get there faster than we think,” James Reuter, associate administrator for the Space Technology Mission Directorate (STMD) at NASA, said during a panel this week at the 37th Space Symposium in Colorado Springs.

Ahead of the Longevity Leaders World Congress, Cambrian’s James Peyer talks stepping stones and silver bullets in geroscience research.

Seattle-based longevity biotech YouthBio Therapeutics has emerged from stealth mode, revealing it is working on the development of “gene therapies aimed at epigenetic rejuvenation, particularly with the help of partial reprogramming by Yamanaka factors.” The company boasts some top longevity science talent, with Dr João Pedro de Magalhães serving as its chief scientific officer and Dr Alejandro Ocampo as lead research collaborator.

Longevity. Technology: Cellular reprogramming is hot, hot hot! YouthBio joins a growing list of companies, including Altos Labs, Shift Bioscience and Turn Bio, among others, all aiming to change the course of human health through this exciting, yet early stage, science. Like everyone else, we’ll be watching all the players very closely – where will the first major breakthrough come from?

Cellular reprogramming is the process by which aged cells can be returned to a pluripotent (embryonic-like) state. This process, which can be achieved using Yamanaka factors, also improves the cells’ aging hallmarks. Partial reprogramming means that Yamanaka factors are induced only for short periods, which is not enough to fully change cells beyond a point of no return but is enough to induce rejuvenation.

A brighter future could be in store for people with a spinal cord injury if new animal research pans out in humans.

Mice that were paralyzed due to severe spinal cord damage regained the ability to walk within four weeks of receiving an experimental injectable therapy, say researchers led by Samuel Stupp of Northwestern University in Chicago.

The research team plans to seek U.S. Food and Drug Administration approval for the treatment to be used in people.
