In a Fierce Desert, Microbe ‘Crusts’ Show How Life Tamed the Land
While all biocrusts perform some degree of weathering, the larger grains of the grit crust are especially suited for it. The process reveals the full potential of microbes to impact their environment. A microbial skin can glue together pebbles, break them down into soil and fertilize that soil with essential nutrients. In effect, the crust… Continue reading In a Fierce Desert, Microbe ‘Crusts’ Show How Life Tamed the Land

A hard whack to the chest at the wrong moment, however, can set up unruly waves of abnormal electrical excitation that are potentially deadly. The resulting kind of arrhythmia may be what caused the football player Damar Hamlin of the Buffalo Bills to… Continue reading Can Math and Physics Save an Arrhythmic Heart?
When Disaster Strikes, Is Climate Change to Blame?
Last November the spring weather in South America jumped from cold to searing. Usually at that time of year people would have been holding backyard barbecues, or asados, in the lingering evening light.

How to Build a Big Prime Number
Over time, researchers developed the aforementioned approaches. The simplest way is just to guess. If you want a prime with 1,000 digits, for example, you could pick a 1,000-digit number at random and then check it. “If it’s not prime, you just try another one, and another, and so on until you find one,” said… Continue reading How to Build a Big Prime Number
World’s Largest Fusion Project Is in Big Trouble, New Documents Reveal
It could be a new world record, although no one involved wants to talk about it. In the south of France, a collaboration among 35 countries has been birthing one of the largest and most ambitious scientific experiments ever conceived: the giant fusion power machine known as the International Thermonuclear Experimental Reactor (ITER).

There’s No Evidence for Claims That Environmentally Friendly Investments Are Bad for the Poor
CLIMATEWIRE | Conservatives are leveraging a new argument against ESG: It’s hurting poor families. Energy analysts say the criticism lacks any supporting evidence. But it builds on Republicans’ intensifying opposition to environmental, social and governance investing, which refers to the practice of considering risks like climate change when making financial decisions. Mandy Gunasekara, a former Trump… Continue reading There’s No Evidence for Claims That Environmentally Friendly Investments Are Bad for the Poor
