A cocktail of steroids and vitamin C, often found in citrus and leafy green produce, might hold the key to treating sepsis. Or, clinical trials might prove it overhyped.

Could Vitamin C Be the Cure for Deadly Infections?

A new protocol that includes this common nutrient could save millions of lives—and has already sparked a raging debate among doctors

The "abortion pill" (actually two separate medications) can be taken up to 10 weeks after pregnancy, according to the FDA.

The Science Behind the “Abortion Pill”

Legal or not, more American women are opting for abortion by medication. We asked doctors: How safe is it?

When it comes to a crowdsourcing campaign, food might be an easier sell than feces. “Food is this amazing platform because we all have a connection to it, we all can relate,” says microbiologist Rachel Dutton. Not that poop isn't relatable, but, you know.

You Are What You Eat, And What You Eat Is Millions of Microbes

Now that they’ve tallied up American feces, researchers are turning to the other half of the microbial equation: food

Don't stop slathering on the sunblock, but a technology being developed in the lab could add an additional layer of protection, by tanning skin cells without UV rays.

Researchers Give Skin Cells a Tan—Without the Sun

Without damaging UV rays, the artificial tan could give that golden glow while protecting against skin cancer.

A baby in the neonatal intensive care unit are often covered in patches and wires for monitoring their vital signs, but new advances mean that soon those wires could be replaced with sensors as thin as a temporary tattoo.

Will These Flexible Skin Patches Replace Wires in Hospitals?

Researchers at Northwestern University have developed "epidermal electronics," thin flexible patches capable of monitoring vital signs and more.

An excerpt from the first road map of Britain, published by John Ogilby when Fiennes was 15, in 1675. No word on whether Fiennes ever saw it, although she did write about visiting a college in Manchester that had a map collection.

Before St. Martin's living digestive system was studied, doctors knew what the digestive system looked like but not how it looked or behaved while working.

This Man's Gunshot Wound Gave Scientists a Window Into Digestion

The relationship between St. Martin and the doctor who experimented on him was ethically dubious at best

The tentacles of the Portuguese man o' war, (which is technically a siphonophore, a group related to jellyfish), contain harpoon-like cells called nematocysts that deliver painful doses of venom.
