NPR reporters and editors are live annotating Monday night's debate. Read the latest fact check, analysis and context here.
If jets of water vapor are indeed erupting from Europa, a spacecraft could potentially fly through them and analyze their chemistry. The moon is believed to have a vast subterranean, saltwater ocean.
China says the 500-hundred meter telescope detected a radio signal originating 1,351 light-years from Earth. One of its uses is scanning for signs of intelligent extraterrestrial life.
If you rely on an insight from your daily horoscopes, you may have been looking at the wrong sign this whole time.
There is only one school in the U.S. where glassblowers can graduate with a degree in making lab equipment. Students learn how to make customized glassware used in cutting-edge scientific experiments.
California is among five states this year where marijuana legalization is on the ballot. But there's concern about if legalizing it will reduce the number of marijuana arrests among African-Americans.
A study by AAA found 16.5 million Americans buy premium gas when their cars don't need it. Director of Automotive Engineering Greg Brannon says drivers waste money when they unnecessarily use premium.
Hillary Clinton and Donald Trump have starkly different views on energy policies. We hear from the people who are advising the candidates on everything from clean energy to fracking.
Harry Selker has spent his life trying to come up with better ways to keep people from dying of heart attacks. Now he's intent on figuring out if a simple, cheap medication could be a game changer.
In the past 50 years, better medical care and healthier habits have greatly reduced the risk of dying young from heart disease. But the obesity epidemic threatens to reverse that happy trend.
Researchers used a new kind of analysis to make a virtual image of a crumbling ancient scroll from Israel. Biblical scholars were able to read the recreated text, which is from Leviticus.

Scientists have discovered a soil microbe with a gene that kills the corn rootworm, an insect that farmers spend $1 billion each year trying to control.
NPR's Robert Siegel interviews Manu Prakash, a physical biologist and inventor at Stanford University, about being awarded a MacArthur fellowship this year. He talks about his work using bioengineering, not just for basic research, but to invent ultra low cost scientific tools, such as microscopes kids can use anywhere in the world.
A scientist in Sweden has started experiments on healthy human embryos in which DNA is altered. The aim is to determine the causes of infertility. It's the first known use of so-called "gene-editing" tools on healthy human embryos, and critics say it could potentially lead society down a very dangerous path.
A Swedish biologist wants to change the genes of healthy human embryos to find ways to treat infertility and perhaps other diseases. The experiments intensify ethical questions genetic engineering.
When Frances Moore Lappe wrote the best-selling Diet For A Small Planet back in 1971, she helped start a conversation about the social and environmental impacts of the foods we choose.
Frances Moore Lappe wrote the book, Diet for a Small Planet, which advocates a vegetarian diet. The book started a conversation about the political, economic and health implications of food choices.
Engineering professor Rebecca Richards-Kortum wins a MacArthur Fellowship for inspiring her students to invent medical devices for the developing world.
The annual MacArthur Fellowships, also known as the MacArthur genius grants have been unveiled. One of the 23 winners is a ground breaking global health engineer.
