A lifetime of love for the charismatic narwhal

An independent scientist working with the Inuit has unraveled many mysteries of the one-tusked ‘unicorn of the sea’

Invasive species are transforming the Everglades

From Burmese pythons and Asian swamp eels to Old World climbing ferns, South Florida hosts hordes of non-native animals and plants. What can be done about the ecological havoc they are wreaking?

To pee or not to pee? That is a question for the bladder — and the brain

How do we sense the need to urinate? The basic urge is surprisingly complex and can go awry as we age.

Spots, stripes and more: Working out the logic of animal patterns

More than 70 years ago, mathematician Alan Turing proposed a mechanism that explained how patterns could emerge from bland uniformity. Scientists are still using his model — and adding new twists — to gain a deeper understanding of animal markings.

The hornet has landed: Scientists combat new honeybee killer in US

An invasive yellow-legged wasp has been decimating beehives in Europe — and bedeviling Georgia since last summer. Researchers are working nest by nest to limit the threat while developing better eradication methods.

Fit for a dog? The latest science on CBD for pets

Though studies are still mixed, and products often inconsistent, many scientists have hope that cannabidiol can help canines and other furry patients suffering from arthritis, allergies and anxiety

The wasps that tamed viruses

To protect and rear their young, some insects have transformed wild viruses into tiny biological weapons

From toxic fungus to soy sauce superstar

Today the koji mold is a master fermenter, but it has a checkered past

The tender art of tadpole parenting

From poison frogs to worm-like caecilians, some amphibians are hardworking and surprisingly creative caregivers

They swim and they spin: Meet the aquatic spiders

Some make nests inside seashells, others tote bubbles of air on their backs. The spiders that went back to water evolved lots of slick survival strategies.

Why are there so many beetle species?

Diet played a key role in the evolution of the vast beetle family tree

How to control chronic wasting disease

A prion sickness similar to mad cow is spreading rapidly through North America’s deer and elk populations. A veterinary microbiologist discusses the options for keeping it in check.

Inching toward a global treaty on plastic pollution

Delegates from 175 nations are working on an international agreement that would tackle the vast amounts of plastic waste in the environment. A marine scientist specializing in plastic pollution discusses the problem and her hopes for the proceedings.

Hunting sky islands for genetic clues to climate resilience

OPINION: Isolated mountaintops are hotbeds of evolutionary adaptation and great places to study how climate change affects ecosystems

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
