How Colossal sold investors on a quest to resurrect a woolly mammoth

There are a growing number of companies interested in CRISPR’s potential to upend medicine. It’s probably safe to say there’s only one company interested in using the gene-editing system to create a living, breathing woolly mammoth. Or, at least, something pretty close to it.  That’s the primary mission of a new company called Colossal. Co-founded […]

Laser-initiated fusion leads the way to safe, affordable clean energy

Siegfried Glenzer Contributor Siegfried Glenzer, a recipient of the Ernest Orlando Lawrence Award, is a professor and high-energy-density division director at Stanford’s SLAC National Accelerator Laboratory and a science adviser for nuclear fusion company Marvel Fusion. The quest to make fusion power a reality recently took a massive step forward. The National Ignition Facility (NIF) […]

The 4 things needed to reach Biden’s ambitious 2050 solar goal

A report on the future of solar energy from the Department of Energy paints a sunny picture, if you will, of the next three decades, at the end of which nearly half the country’s energy will be provided by the sun. But for that to happen, big pushes need to happen along four major lines: […]

Heimdal pulls CO2 and cement-making materials out of seawater using renewable energy

One of the consequences of rising CO2 levels in our atmosphere is that levels also rise proportionately in the ocean, harming wildlife and changing ecosystems. Heimdal is a startup working to pull that CO2 back out at scale using renewable energy and producing carbon-negative industrial materials, including limestone for making concrete, in the process, and […]

Avalo uses machine learning to accelerate the adaptation of crops to climate change

Climate change is affecting farming all over the world, and solutions are seldom simple. But if you could plant crops that resisted the heat, cold, or drought instead of moving a thousand miles away, wouldn’t you? Avalo helps plants like these become a reality using AI-powered genome analysis that can reduce the time and money […]

44.01 secures $5M to turn billions of tons of carbon dioxide to stone

Reducing global greenhouse gas emissions is an important goal, but another challenge awaits: lowering the levels of CO2 and other substances already in the atmosphere. One promising approach turns the gas into an ordinary mineral through entirely natural processes; 44.01 hopes to perform this process at scale using vast deposits of precursor materials and a […]

$100M donation powers decade-long moonshot to create solar satellites that beam power to Earth

It sounds like a plan concocted by a supervillain, if that villain’s dastardly end was to provide cheap, clean power all over the world: launch a set of three-kilometer-wide solar arrays that beam the sun’s energy to the surface of the Earth. Even the price tag seems gleaned from pop fiction: one hundred million dollars. […]

Swarm debuts $499 Evaluation Kit for consumers and tinkerers

Satellite connectivity company Swarm’s new product will give anyone the ability to create a messaging or Internet of Things (IoT) device, whether that be a hiker looking to stay connected off the grid or a hobbyist wanting to track the weather. The Swarm Evaluation Kit is an all-in-one product that includes a Swarm Tile, the […]

Pivot Bio rakes in $430M round D as modified microbes prove their worth in agriculture

Pivot Bio makes fertilizer — but not directly. Its modified microorganisms are added to soil and they produce nitrogen that would otherwise have to be trucked in and dumped there. This biotech-powered approach can save farmers money and time and ultimately may be easier on the environment — a huge opportunity that investors have plowed […]

Stumble-proof robot adapts to challenging terrain in real time

Robots have a hard time improvising, and encountering an unusual surface or obstacle usually means an abrupt stop or hard fall. But researchers at Facebook AI have created a new model for robotic locomotion that adapts in real time to any terrain it encounters, changing its gait on the fly to keep trucking when it […]
