VIDEO: Functional Liver Tissue Can Now Be Grown From Stem Cells

By mixing different types of stem cells in petri dishes, researchers created liver “buds” that effectively filtered blood when implanted in mice

The habitual use of antibiotics at industrial farming operations to promote growth can lead to the development of bacteria resistant to the drugs.

Factory Farms May Be Ground-Zero For Drug Resistant Staph Bacteria

Staph microbes with resistance to common treatments are much more common in industrial farms than antibiotic-free operations

How do we resist when burgers and bacon beckon?

Can We Be Tricked into Not Eating So Much?

Just posting calorie counts isn’t very effective. What may work, though, is framing overeating in terms everyone understands

Researchers don't have to turn back the clock with this new stem cell breakthrough.

Why Do We Yawn and Why Is It Contagious?

Pinpointing exactly why we yawn is a tough task, but the latest research suggests that our sleepy sighs help to regulate the temperature of our brains

Our uncommon shoulder flexibility allows us to throw extremely fast, as compared to other primates—a trait we likely evolved two million years ago to aid with hunting.

Research says dogs have learned to behave like children.

Are Dogs Now Just Furry Kids?

Research is showing how much the bonds between dogs and their owners have become like a parent-child relationship

Why We Should Study Cancer Like We Study Ecosystems

Like pine beetles sickening a forest as they spread, cancer can be seen as a disruption in the balance of a complex microenvironment in the human body

What Scientists Now Know About Repairing Memories

Recent research suggests that the brain rebuilds a memory every time it is recalled. And that creates a window of opportunity for changing it

One bionic ear, fresh off the printer.

How One Day Everything Could Be Recycled

Mix 3-D printers and biomimicry and what do you get? Products that are as strong, resilient, versatile—and biodegradable—as most things in nature

This Castle’s Toilet Still Holds Parasites From Crusaders’ Feces

The presence of whipworm and roundworm eggs suggest that crusaders were especially predisposed to death by malnutrition

Science gives fathers some props.

10 More Things We’ve Learned About Dads

Scientists keep finding reasons why fathers matter. They also think it’s not a bad idea for dads to ask their kids, “How am I doing?”

Scientists Sequence DNA of Bacteria Responsible for Medieval Leprosy

Genetic information gathered from centuries-old exhumed bones reveals that the infection hasn’t changed much in the past 1,000 years

Languages that evolve at high elevations are more likely to include a sound that’s easier to make when the air is thinner, new research shows.

Do Geography and Altitude Shape the Sounds of a Language?

Emerging research indicates that low doses of the active chemical psilocybin can have positive psychiatric effects.

Could “Magic” Mushrooms Be Used to Treat Anxiety and Depression?

Emerging research indicates that low doses of the active chemical psilocybin, found in the fungi, can have positive psychiatric effects

A Neanderthal rib bone was discovered to have a lesion associated with a tumor (top specimen). The missing bone tissue is starkly apparent compared to a normal Neanderthal rib shown below.

Evidence for the Oldest Ever Bone Tumor Was Just Found in a Neanderthal Fossil

A 120,000-year-old rib bone, originally found in Croatia, shows that tumors aren’t always caused by exposure to pollution

VIDEO: This Helicopter is Controlled Entirely By A Person’s Thoughts

A new device can read your brain patterns to steer a toy helicopter—the mere thought of clenching your right fist veers the chopper right

Eric D. Green is the director of the National Human Genome Research Institute.

The Work Is Only Beginning on Understanding the Human Genome

Ten years ago, scientists released a map of our genetic blueprint. But, as Eric D. Green explains, there are many more mysteries left to unravel

The Ginger.io app looks for health clues in a phone log trail.

How You Use Your Phone May Tip Off Health Problems

Among the new technology geared to preventive health care is an app that tracks your social behavior and has been described as a human “check engine” light

A neurotransmitter called Nppb, we now know, plays a vital role in the sensation of an itch—and removing it can prevent itchiness entirely.
