Nature is slowing down, and its ability to regenerate is failing in the face of climate change, according to the authors of a new analysis of the speed of species turnover in ecosystems across the world.

The finding comes as a big surprise to many ecologists. They have long predicted that nature will respond to climate change and humanity’s other assaults by rampin...

On a dirt road that cuts through the Rio Novo settlement in the southeast of Pará state, battered motorcycles carry small loads of organic food to sell in the city, while passing trucks loaded with minerals for export.

Parauapebas, Brazil’s so-called “mining capital,” hosts numerous rural worker communities, including the 5,000 families of 

Many medical devices need to be sterile to be used safely. But sterilizing a pacemaker, catheter, or other device with steam or heat could damage its structural integrity. So medical device manufacturers turn to the chemical compound ethylene oxide, which is highly effective at killing microbes at low concentrations and allows companies to meet the Food and Drug Administratio...

You are here because of a single, all-important enzyme. But don’t look inward to find ribulose-­1,5-­bisphosphate carboxylase/oxygenase, known more mercifully among scientists as rubisco. Instead, look to the food you eat and the trees that manufacture oxygen, as this is the protein that makes photosynthesis possible. Without it, life on Earth as we know it would not exist.

You’ve heard of the Amazon rainforest, but have you heard of its neighbor, the cerrado? It’s a vast savanna — the most biodiverse in the world — of swaying grasses punctuated by trees. But its most remarkable feature, and its climate superpower, is hidden underground within its wetlands: concentrated carbon known as peat.

New research suggests that the cerrado is <...
