How an 1800s Midwife Solved a Poisonous Mystery

For decades before Doctor Anna’s discovery, “milk sickness” terrorized the Midwest, killing thousands of Americans on the frontier

By recording activity of specific neurons in the brain, researchers aim to pick up signals of intended speech.

The Brain-Computer Interfaces That Could Give Locked-In Patients a Voice

Implanted devices record the brain waves associated with speech and then use computer algorithms to translate the intended messages

New mental health treatments employ psychedelics and virtual reality.

The Future of Mental Health

A renewed focus on our brain’s ability to cope with trauma sparks a special series of stories about the latest advancements in treatments of mental illness

This functional connectivity map, a kind of “fingerprint” of the brain, displays how different regions interact with each other in 12-year-olds. The map was constructed from resting-state MRIs, where participants were lying down and not completing a task. Larger red circles denote brain “nodes” with more connections.

Can a ‘Fingerprint’ of Your Brain Help Predict Disorders?

Using new medical imaging techniques, researchers are working to identify early signs of developmental disorders and mental illness

To collect a saliva sample, technicians instruct a person to tilt their head for two to five minutes and spit the accumulated saliva into a sterile tube. The saliva-filled tube is kept on ice and sent to the laboratory to test for the presence of biomarkers for cancer or other diseases.

Is Saliva the Next Frontier in Cancer Detection?

Scientists are finding tumor signals in spit that could be key to developing diagnostic tests for various types of cancer

The cabbage soup diet of the 1950s allowed the indulgence in as much cabbage soup as one could consume.

The Seesawing History of Fad Diets

Since dieting began in the 1830s, the ever-changing nutritional advice has skimped on science

Saliva impacts how different foods taste.

How Saliva Changes the Flavor of Food

The liquid impacts how we perceive taste and can influence what we choose to eat

Debra Babalola and Shefali Bohra invented Dotplot, a device that can help users monitor their breast health.

A New Tool Could Help Detect Breast Cancer Earlier

Dotplot gives users real-time feedback and builds a personalized map of their chests

An impala runs away from a cheetah.

How the Brain Calculates a Quick Escape

Scientists are beginning to unravel the complex circuitry behind the split-second decision to beat a hasty retreat

A growing movement is underway to halt chronic disease by protecting brains and bodies from the biological fallout of aging.

Can This New A.I. Tool Help Detect Blood Poisoning?

The algorithm scans electronic records and may reduce sepsis deaths, but widespread adoption could be a challenge

A bus being treated with ultraviolet light in Shanghai, China. Although types of UV light are already in use to decontaminate vehicles and indoor spaces, the wavelengths used are dangerous to people. Researchers hope that wavelengths of far-UVC light can be used harmlessly when people are present.

Covid-19

Could UV Light Reduce the Spread of Covid-19 in Indoor Spaces?

Some wavelengths of light in a range called far-UVC kill microbes in experiments and appear to be harmless to people

From the lab to the art gallery, the latest efforts to understand the fragrant, musky, stinky and utterly baffling world of your nose

The da Vinci surgical robot, shown here on a US Navy hospital ship, is one of the most widely used devices to assist doctors in laparoscopic surgery. The procedure — in which tools are inserted through tiny holes in the abdomen instead of cutting a long incision — allows patients to recover more quickly.

The Past, Present and Future of Robotic Surgery

After decades of merely assisting doctors, are sophisticated machines ready to take charge?

Scientists are beginning to understand when and why minds start to wander.
