Like us, wasps don’t forget a face

Paper wasps have brains that are less than a millionth the size of the human brain, yet new research shows they have a similar ability to recognize and remember a familiar face.

Massive black holes shatter record

An international team of astronomers has discovered two gigantic black holes with masses about 10 billion times the mass of our sun. These black holes have a mass more than 50 percent greater than any other previously measured.

Stretch sensor like taffy. Watch it bounce back

A transparent sensor that is so stretchy it can be pulled to twice its original length and then bounce back perfectly has potential for use with prosthetic limbs, robotics, and touch-sensitive computer displays.

Equation explains forces that repel water, oil

A new equation is the first to predict the hydrophobic interactions of molecules. Such interactions explain why oil and water don’t mix, how proteins are structured, and what holds biological membranes together. The new formula is expected to affect applications in water filtration, membrane separations, biomedical research, gene therapy methods, biofuel production, and food chemistry.

Gas ‘bullets’ shoot from giant black hole

Astronomers have uncovered some striking features in the gases emitted from the regions close to one of the brightest supermassive black holes known to exist. The black hole has a mass 300 million times that of the sun.

How to make cameras auto-focus like eyes

A new algorithm suggests there is information lurking in images that cameras have yet to tap. Like a camera, the human eye has an auto-focusing system, but human auto-focusing rarely makes mistakes. And unlike a camera, humans do not require trial and error to focus an object.

New class of painkillers: Ibuprofen 2.0?

Scientists thought there was little left to learn about a class of medications that includes ibuprofen, but a recent discovery raises the possibility of a new class of pain relievers.

Birds May Identify Their Relatives By Smell

Penguins appear to use smell to determine if they are related to a potential mate, which suggests birds may have a more highly developed sense of smell than researchers previously thought.

Satellite killers: Meteoroids vs. space junk

At any given time there are somewhere in the neighborhood of 22,000 pieces of debris 10 centimeters or larger zipping along in orbit at speeds of seven kilometers per second, according to the U.S. Air Force. But Sigrid Close, an assistant professor of aeronautics and astronautics at Stanford University, says billions of very tiny meteoroids do more damage to satellites and other spacecraft than all the space junk orbiting Earth.

Tiny devices in tumors generate oxygen to boost chemo

Micro devices implanted inside tumors to generate oxygen boost the cancer-killing power of radiation and chemotherapy. The technology is designed to treat solid tumors that are hypoxic at the center, meaning the core contains low oxygen levels.
