It’s very early days—so don’t ditch your glasses just yet.

These Lenses Zoom With a Couple Blinks of Your Eyes

Researchers have developed a soft polymer lens that changes shape based on electrical input

The technology involves a system of sensors that detect the minuscule neuromuscular signals sent by the brain to the vocal cords and muscles of the throat and tongue.

This Device Can Hear You Talking to Yourself

AlterEgo could help people with communication or memory problems by broadcasting internal monologues

Will Artificial Intelligence Improve Health Care for Everyone?

A.I.-driven medical tools could democratize health care, but some worry they could also worsen inequalities

The team has applied for a patent for the material (shown here in a petri dish) and continues to test it at the micro- and nano-scale to better understand how it works.

How Scientists Are Using Eggshells to Grow New Bone

People with bones damaged by accidents, cancer or aging could one day benefit from bone grafts strengthened with chicken eggshells

The “cry language recognition algorithm” was trained on recordings of baby cries taken from a hospital's neonatal intensive care unit.

Women Who Shaped History

The Woman Who Revealed the Missing Link Between Viruses and Cancer

Today, vaccinating against cervical cancer is routine. But before Sarah Stewart, scientists dismissed the idea of a cancer-preventing vaccine as ludicrous

In 1954, John Kirklin of the Mayo Clinic created the Mayo-Gibbon heart-lung machine when he modified a design pioneered by John Gibbon. The machine is now in the collection of the Smithsonian National Museum of American History.

This 1950s Heart-Lung Machine Revolutionized Cardiac Surgery

Open-heart procedures evolved rapidly once Mayo Clinic surgeon John Kirklin made his improvements to an earlier invention

Mosquito-borne diseases, such as Zika, malaria and Rift Valley Fever, threaten billions of people around the world.

How Scientists Use Climate Models to Predict Mosquito-Borne Disease Outbreaks

The ebb and flow of rainy seasons corresponds with the hatching of millions of mosquitoes—and the spread of diseases they carry

New Nanotechnology Imaging Technique Sheds Light on DNA Structure

The new technology could help pinpoint how errors occur in DNA replication, which can cause cancer and other diseases

Using a brain implant with a series of electrodes, scientists can read neurological signals and translate the brain activity into spoken language.

Brain Implant Device Allows People With Speech Impairments to Communicate With Their Minds

A new brain-computer interface translates neurological signals into complete sentences

The Family That Feels Almost No Pain

An Italian clan’s curious insensitivity to pain has piqued the interest of geneticists seeking a new understanding of how to treat physical suffering

The “Human Organ Monitoring Apparatus for Long-distance Travel” (HOMAL) measures the biophyisiologic properties—temperature, pressure, vibration and altitude—of an organ.

Drones’ Newest Cargo Might Just Be Human Organs

Surgeon Joseph Scalea is developing a cooler, biosensors and an online platform with GPS to monitor organs in transport in real time

Seventeen-year-old Ayush Alag is one of 40 finalists in this year’s Regeneron Science Talent Search

The microbes in human guts, including bacteria, archaea, fungi and viruses, play a significant role in how our bodies respond to diseases and treatments.

How the Microbiome Could Be the Key to New Cancer Treatments

The effectiveness of drugs that help the immune system fight cancer cells appears to depend on bacteria in the gut

We appear to be experiencing a loneliness epidemic.

Can a Pill Fight Loneliness?

A University of Chicago scientist thinks the hormone pregnenolone might reduce lonely people’s fear of connecting—and their risk of serious health problems
