Eclipses come in many forms
Eclipses are one of nature’s most awesome spectacles, and scientists have learned a lot by observing them and related celestial alignments — occultations and transits.
- Tech
Scientists turn toy into valuable tool for medical diagnosis
A human-powered ‘paperfuge,’ inspired by a toy, could serve as an easy, low-cost way to aid in medical diagnoses, even in regions of the world lacking access to electricity.
- Science & Society
Shrimp on treadmills? Some science only sounds silly
Research that may seem silly, at first glance, often has a rewarding aim. Here are some examples.
- Physics
How to chill an object by sending its heat into space
Researchers have designed a device that can cool an object by radiating its energy into outer space. Think of it as a solar panel in reverse.
- Tech
Magnets may one day cull deadly germs from blood
A new technique for slowing the deadly condition called sepsis would use tiny iron particles and magnets.
- Physics
Explainer: How batteries and capacitors differ
Both batteries and capacitors can power electronic devices. Each, however, has different properties which may provide benefits — or limitations.
- Computing
LEDs offer new way to kill germs in water
Growing ultraviolet-light-emitting diodes on thin, flexible sheets of metal holds promise for water disinfection and other applications.
- Physics
Wind power gets downsized — but in a good way
Two young scientists have developed ways to tap into wind power on a small scale.

How not to grin and bear it
Three teen researchers who took part in this year’s Broadcom MASTERS competition seek to help those who clench and grind their teeth.
- Animals
These young inventors had to make like a crab
This year’s top challenge for Broadcom MASTERS finalists was to design and build a robotic arm based on a crab’s arm and claw.
- Environment
Rocket nozzle research propels teen to big win
A 13-year old won the top prize at this year’s Broadcom MASTERS science competition. She had determined the best shape for a rocket nozzle.
- Chemistry
New coating for metals could cut engine wear
Scientists have developed a new coating for engine parts that could reduce friction and engine wear. One big benefit: Cars may require fewer oil changes.
