Jagged graphene can slice into cell membranes

Researchers from Brown University have shown how tiny graphene microsheets — ultra-thin materials with a number of commercial applications — could be big trouble...

Muscle power: Bats power take-off using recycled energy

Bats are uniquely able to stretch and store energy in their bicep and tricep tendons during take-off and climbing flight, giving them an extra...

Polymers key to oral protein-based drugs

For protein-based drugs such as insulin to be taken orally rather than injected, bioengineers need to find a way to shuttle them safely through...

Computer models figure out sickle cell crisis

Using powerful computer models, researchers from Brown University have shown for the first time how different types of red blood cells interact to cause...

Pistil leads pollen in life-and-death dance

Millions of times on a spring day there is a dramatic biomolecular tango where the flower, rather than adorning a dancer’s teeth, is the...

Noble gases hitch a ride on hydrous minerals

The noble gases get their collective moniker from their tendency toward snobbishness. The six elements in the family, which includes helium and neon, don’t...

Method removes heavy metals from water

An unfortunate consequence of many industrial and manufacturing practices, from textile factories to metalworking operations, is the release of heavy metals in waterways. Those...

Researchers find best routes to self-assembling 3-D shapes

Material chemists and engineers would love to figure out how to create self-assembling shells, containers or structures that could be used as tiny drug-carrying containers or to build 3-D sensors and electronic de...

Chinese health coverage increases with new government efforts

Health care coverage increased dramatically in parts of China between 1997 and 2006, a period when government interventions were implemented to improve access to health care, with particularly striking upswings in...

Are doing harm and allowing harm equivalent? Ask fMRI

People typically say they are invoking an ethical principle when they judge acts that cause harm more harshly than willful inaction that allows that same harm to occur. That difference is even codified in crimin...
