Horseshoe crabs evolved 445 million years ago and have been around for 1,500 times longer than Homo sapiens. It was not until the 20th century, however, that scientists discovered life-saving properties in their blood.

Horseshoe Crab Blood Has Long Helped Us Make Safe Medicines. Now, Alternatives That Spare the Ancient Creatures Might Be Breaking Through

An enzyme in the blue blood has been key to testing vaccines since the 1980s, raising concerns for the crabs’ population. But regulatory approval and new data are signaling the tide may be turning

Postpartum depression affects some one in eight women in the United States. It typically occurs in the first weeks after childbirth, after a sudden drop in levels of estrogen and progesterone.

A Blood Test Can Now Predict a Mother’s Risk of Postpartum Depression

Scientists are learning more about this leading complication of childbirth, and treatments are improving

People with a rare form of epilepsy have reported feelings of bliss just before having a seizure. A French Swiss neurologist has pinned down where this “aura” originates in the brain in hopes that one day, that feeling might be reproduced non-invasively in others.

Some People Experience Blissful Ecstasy Right Before a Seizure. Could Understanding This Feeling Help Treat Depression?

A neurologist shares her thoughts and research about “ecstatic epilepsy” in a wide-ranging conversation on how we perceive the world—and create the world we perceive

The patient looks through measuring goggles at a series of markers on a grid. 

Can a Medical Device Restore Your Balance?

Nearly two million people worldwide have lost the simple ability to feel steady. Now researchers have developed an experimental medical implant that promises to restore the sensory machinery responsible for balance

Heart disease is the leading cause of death globally, according to the World Health Organization.

This 14-Year-Old Built an App That Detects Heart Diseases in Seconds

Siddarth Nandyala wants to put his tool in the hands of medical professionals so that they can catch cardiovascular abnormalities in their early stages

New research is revealing how climate change is impacting our eyes.

Climate Change Is Threatening Eye Health in Disturbing Ways

Cataracts, pinkeye and other ocular disorders are linked to heat, air pollution and higher UV exposure

Hoping to stave off a global health crisis, scientists are breeding a new generation of crops that suck the mineral, which helps the thyroid and immune system, from soil

A vast mosaic of cells, some that are identical and some that are slightly different, make up the human body.

Why Is Every Human Being Riddled With Genetic Errors?

Your body is a collection of cells carrying thousands of genetic mistakes accrued over a lifetime—many harmless, some bad and at least a few that may be good for you

Some people are genetically built to require less sleep than the rest of us.

Why Do Some People Thrive on So Little Sleep?

Short sleepers cruise by on four to six hours a night and don’t seem to suffer ill effects
