Harmful Bacteria Masquerade as Red Blood Cells to Evade the Immune System

Studying the stealthy strategy could help researchers develop new treatments for group A strep infections, which kill more than 500,000 people each year

The bacterium Escherichia coli, shown here, moves itself with propeller-like structures called flagella; it is one of the mobile microbes scientists have linked to cargo-carrying structures to form biohybrid microrobots.

How Tiny, Microbe-Propelled Bots Could Deliver Drugs in Our Bodies

Researchers are developing 'hybrid biological microrobots' to target cancer and do other work in the body

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.

The accelerated decomposition method transforms remains into soil and uses just an eighth of the energy required for cremation

Melting Glaciers on Denali Will Unleash Tons of Human Poop

An estimated 66 tons of feces left behind by climbers is coming out of the deep freeze on North America's highest peak

The cactus spines, bound together with yucca leaves, are still stained with black ink

These 2,000-Year-Old Needles, Still Sharp, Are the Oldest Tattooing Instruments Found in the Southwestern U.S.

Originally excavated in 1972, the pronged cactus-spine tool languished in storage for more than 40 years before its true purpose was recognized

Hanging Out in Space Deforms Brain Tissue, New Cosmonaut Study Suggests

While gray matter shrinks, cerebrospinal fluid increases. What's more: These changes do not completely resolve once back on Earth.

Mount Vesuvius Boiled Its Victims' Blood and Caused Their Skulls to Explode

A new study of residue on skeletons from the 79 A.D. eruption indicates Herculaneum was hit with a 400 to 900 degree pyroclastic flow

"Propped" 1992

Jenny Saville Takes Title of Most Expensive Living Female Artist

Her 1992 nude self-portrait "Propped" sold for $12.4 million. But the record-breaking price lags behind the amount paid to the men's holder of the title

Study participants Kelly Thomas, who was paralyzed in a truck crash and Jeff Marquis, who was injured while mountain biking.

How Implanted Electrodes Helped Paralyzed People Stand and Walk Again

Two new studies demonstrate that epidural stimulation and intensive therapy can help people overcome paralysis from spinal cord injuries

The next generation of robotic hands will have to be extremely dexterous, but also simple to build. The three-fingered version designed by engineer Matei Ciocarlie can adapt to a wide array of objects, yet hold each of them in a firm grasp (composite image shows the more open hold on an apple and a tighter pinch on a marker). Its semi-soft fingers are controlled by a series of wire “tendons” that lead to a single motor in a robot’s wrist.

The Quest to Build Robotic Hands

Humans can readily manipulate all kinds of objects. But robots need better mechanics—and a lot more intelligence
