This startup has engineered a clever way to reuse waste heat from cloud computing
The idea of using the wasted heat of computing to do something else has been mooted plenty of times before. Now, UK startup Heata is actually doing it. When you sign up, it places a server in your home, where it connects via your Wi-Fi network to similar servers in other homes—all of which process data from companies that pay it for cloud computing services.
Each server prevents one ton of carbon dioxide equivalent per year from being emitted and saves homeowners an average of £250 on hot water annually, a considerable discount in a country where many inhabitants struggle to afford heat.
The clever thing is that it provides a way to use electricity twice—providing services to the rapidly growing cloud computing industry and also providing domestic hot water—at a time when energy efficiency matters more than ever. Read the full story.

Tiny faux organs could crack the mystery of menstruation
A group of scientists are using new tools akin to miniature organs to study a poorly understood—and frequently problematic—part of human physiology: menstruation.
Heavy, sometimes debilitating periods strike at least a third of people who menstruate at some point in their lives, causing some to regularly miss work or school. Anemia threatens about two-thirds of people with heavy periods. Many people desperately need treatments to make their period more manageable, but it’s difficult for scientists to design medications without understanding how menstruation really works.
That understanding could be in the works, thanks to endometrial organoids—biomedical tools made from bits of the tissue that lines the uterus. The research is still very much in its infancy. But organoids have already provided insights into why menstruation is routine for some people and fraught for others. Some researchers are hopeful that these early results mark the dawn of a new era.

The big story
This fuel plant will use agricultural waste to combat climate change
February 2022
A startup called Mote plans to build a new type of fuel-producing plant in California’s fertile Central Valley that would, if it works as hoped, continually capture and bury carbon dioxide, starting from 2024.
It’s among a growing number of efforts to commercialize a concept first proposed two decades ago as a means of combating climate change, known as bioenergy with carbon capture and sequestration, or BECCS.
It’s an ambitious plan. However, there are serious challenges to doing BECCS affordably and in ways that reliably suck down significant levels of carbon dioxide. Read the full story.
