The gale-force winds around one quasar whip by at almost 200 million kilometers per hour. That’s 625,000 times faster than the strongest hurricanes on Earth.
Nano-gold is the new black, at least when it comes to absorbing heat. When tiny gold particles get together, they become energy super-absorbers — turning them black.
A new study overturns 150 years of thinking about Yellowstone’s geysers. Carbon dioxide, not just hot water, may be driving those spectacular eruptions.
A newfound bacterium halts the tooth erosion that leads to cavities. This germ or one like it might one day be added to toothpaste or mouthwash.
Making their own clouds has shown scientists how the fattest water droplets form. Understanding this could lead to better forecasts of climate change.
Want to decrease athletic injuries? Part of the answer may be to engage in more, and more varied, sports.
Risks of tremors in some central U.S. states are as high as those in quake-prone California. The reason: waste fluids from oil and gas drilling.
Chemists screen blood for disease markers by adapting a common DNA test. The test can find disease earlier, when it also may be easier to treat.
Whether an artificial leg is on the right or left side of the body may affect how fast runners can take a turn.
A chemical test of tyrannosaur bone can determine whether the dino was pregnant — and therefore a female.
Scientists had suspected extreme meteorite impacts might turn graphite into an unusual type of diamond. Now they’ve seen it happen — in under a nanosecond.
When two black holes collided, they released a lot of energy in gravity waves. How much? How about 36 septillion yottawatts of power!
Breathing dirty Beijing air made rats heavier and less healthy than rats breathing clean air. Scientists now worry such polluted air may do the same thing to people.
Some experts argue that breakfast is the most important meal of the day — especially for keeping school-age kids at a healthy weight.
Scientists were hoping to build better biofuels. Instead they discovered that fatter yeast cells live longer than lean ones.
Bumblebees prefer petals that aren’t overly shimmery. This suggests plants are attuned to what insects see.
People with sensitive teeth can find routine dental cleanings painful. But bubbles might pave way to no-touch — and pain-free — cleaning for these people.
Pets make great subjects for research. These scientists work to make our animals — and us — healthier and happier.
In a recent study, people rated acne as one of the most upsetting skin conditions. Many believed myths and misconceptions about zits.
The Zika virus is spreading in the Americas. There has also been an uptick in cases of Guillain-Barré syndrome. Scientists think the two are linked.
An experiment with modern-day humans shows how slicing meat could have saved human ancestors energy — and let their bodies and brains get bigger.
Drugs must past safety testing before they can be sold. But food supplements don’t have to meet the same standards.
Dietary supplements made from plants may not contain all of the chemicals that usually make a particular plant healthy for humans.
Sucralose — sold in stores as Splenda — has begun turning up in seawater. This raises concern about the fake sweetener’s impacts on the environment.
Why just crack an egg? Make the shell into itty bitty bits and use them to build a more biodegradable plastic. New research shows how.
A massive methane release from a single leaky underground well spewed as much of the greenhouse gas into the air as a mid-sized European country does in an entire year.
FabLab is a new series that brings science, technology, engineering and math subjects to TV and the Web.
New, slime-oozing coating might someday help reduce ice and snow buildups on road signs and aircraft wings. The inspiration? The goo produced by slugs.
