Moving trees north to save the forests

As the world warms, trees in forests such as those in Minnesota will no longer be adapted to their local climates. That’s where assisted migration comes in.

Losing the connection between the Andes and the Amazon: A price of peace in Colombia

The South American country, where the biodiversity of the Andes meets that of the Amazon, is losing the great natural wealth of some 1,500 square kilometers of forest each year, mainly in areas formerly under guerrilla control

Getting rid of bed bugs: Trickier than ever

The blood-sucking insects now show up in two varieties and are resistant to many pesticides. New eradication strategies include fungal spores and nasty human odors.

Indigenous languages are founts of environmental knowledge

Peoples who live close to nature have a rich lore of plants, animals and landscapes embedded in their mother tongues — which may hold vital clues to protecting biodiversity

Forests are under attack from invasive species

OPINION: International commerce and travel bring ecological destruction to the world’s most cherished natural places. We need to do more to stop the assault.

CRISPR gene editing: Moving closer to home

With the first medical therapy approved and systems like CRISPR-Cas showing up in complex cells, there’s a lot going on in the genome editing field. Here’s our primer.

How shade coffee lends conservation a hand

When managed in the right way, the farms that provide our morning brew can be a refuge for plant and animal biodiversity

Genes and heart disease: Finally making the link

Polygenic risk scores — a patient’s chance, based on tiny DNA variants, of developing cardiovascular disease, breast cancer and more — are coming to clinics. But there are kinks to iron out and accuracy remains an issue.

How gut bacteria connect to Parkinson’s disease

Growing evidence suggests a link between the debilitating neurological illness and the microbes that live in our intestines. The vagus nerve may be a pathway.

The growing link between microbes, mood and mental health

New research suggests that to maintain a healthy brain, we should tend our gut microbiome. The best way to do that right now is not through pills and supplements, but better food.

Neanderthals: More knowable now than ever

They have held our fascination ever since we first identified their remains. Today, thanks to new artifacts and technologies, findings about our closest relatives are coming thick and fast.

In the Great Pacific Garbage Patch, new marine ecosystems are flourishing

Sea life, stuck to plastic bottles and other human trash, has journeyed far from coastal habitats — and may threaten local species

Untangling the genetics that underlie our facial features

After turning up hundreds of genes with hard-to-predict effects, some scientists are now probing the grander developmental processes that shape face geometry
