Evidence builds for ways that the brain actively erases memories
The cryobank is a rich source of genetic knowledge of hundreds of creatures. It may one day be used to bring endangered species back from the brink and deepen the gene pool of wild populations.
From identity to national politics, gastronomical conversations can reflect who we are, and who we are not
New technologies mean we won’t just see and hear digital information. We’ll also feel it.

Marco Sardiello explains how problems with the cell’s lysosomes lead to disease
By decoding brain activity with electrical implants, computers can help disabled people move a robotic arm — or their own
Being bilingual benefits children as they learn to speak — and adults as they age
Evolution made insect ears many times over, resulting in a dazzling variety of forms found in spots all over the body. Biologists are digging deep into some of those ears to figure out how and why they came to be.

The same taste receptors found on the tongue are in the stomach, intestines and elsewhere, too. What are they doing there? Well, a lot.
The giant genomes of these struggling amphibians tell a story of outsider invasions, assault by disease and cross-species sex. A geneticist explains.
Taking advantage of “natural experiments,” researchers analyze data to look at what works
Five new things we’re learning about the extinct animals and their ancient kin
Economists tracking changes post-recession say safeguards should reduce the vast vulnerabilities seen 10 years ago. But putting out fires may be harder.
Timeline: Major moments of the 2008 global financial crisis
Travelers’ desire for intimate encounters with wildlife may threaten the animals they love
Scientists are developing AI systems called deep neural nets that can read medical images and detect disease — with astonishing efficiency

An environmental historian looks at how Americans treat corpses and what it means
Space oddities may help reveal dark matter and other secrets in the Milky Way. Astronomer Warren Brown explains.
Bat genomes are full of clever tricks that are treats for biology and medical science — it’s why scientists want to sequence them all
COMIC: Bite marks, shoe prints, crime-scene fibers: Matches to suspects are often far shakier than courtroom experts claim. Better statistical methods — among them, a little beast known as the “likelihood ratio” — can cut down on wrong convictions.

From spotting leaks to patrolling for pathogens, flying robots are taking up chores on the farm.
Clues hidden in today’s orbits hint at the violent origins of the solar system — and a rogue giant kicked out long ago.
America has grown obese on processed, sugary and deceptively cheap foods. Some blame policies enshrined in an unwieldy, bloated beast of legislation.
A newfound peace has spurred the hunt for disease-resistant wild cacao within the nation’s borders. What scientists find could help the country expand its role in the global trade.
