Electrical stimulation of the brain may help people who stutter
When Guillermo Mejias was 7 years old, his parents sent him out to buy bread during a family holiday in southern Spain. Mejias still remembers his growing anxiety as he walked to the bakery, repeating what he would say over and over in his head. But when the moment arrived, he was unable to produce a single word. He recalls returning empty-handed, ashamed, and wondering what to tell his...
Democrats lobby for high-tech immigration reforms in innovation bill before Congress
The shape of U.S. research is at stake as Congress tries to reconcile competing versions of a massive bill, 2 years in the making, aimed at bolstering U.S. competitiveness with China in research and high-tech manufacturing.
The bills would not only authorize spending hundreds of billions of additional dollars on research, but also set out new policies on...
Researchers investigate intricacies in superconductors with hopes to support quantum computer development
Ryan Day studies superconductors. Materials that conduct electricity perfectly, losing no energy to heat and resistance. Specifically, the University of California, Berkeley scientist studies how superconductors can coexist with their opposites; insulating materials that stop the flow of electrons.
NASA's Webb to uncover riches of the early universe
For decades, telescopes have helped us capture light from galaxies that formed as far back as 400 million years after the big bang—incredibly early in the context of the universe's 13.8-billion-year history. But what were galaxies like that existed even earlier, when the universe was semi-transparent at the beginning of a period known as the Era of Reionization? NASA's next flagship observatory,...
Curiosity captures stunning views of a changing Mars landscape
For the past year, NASA's Curiosity Mars rover has been traveling through a transition zone from a clay-rich region to one filled with a salty mineral called sulfate. While the science team targeted the clay-rich region and the sulfate-laden one for evidence each can offer about Mars' watery past, the transition zone is proving to be scientifically fascinating as well. In fact, this transition may...
What did Megalodon eat? Anything it wanted, including other predators
New Princeton research shows that prehistoric megatooth sharks—the biggest sharks that ever lived—were apex predators at the highest level ever measured.
Where once were black boxes, a new statistical tool illuminates
Researchers at the National Institute of Standards and Technology (NIST) have developed a new statistical tool that they have used to predict protein function. Not only could it help with the difficult job of altering proteins in practically useful ways, but it also works by methods that are fully interpretable—an advantage over the conventional artificial intelligence (AI) that has aided with...
Wildfire threatens unspoiled Georgia island rich in history
Wildfires sparked by lightning have scorched hundreds of acres on this unspoiled island off the Georgia coast, where crews are battling to protect plantation ruins, the remnants of a 16th century Spanish mission and archaeological sites that have yielded human artifacts thousands of years old.
Florida team hauls in 18-foot, 215-pound Burmese python
A team of biologists recently hauled in the heaviest Burmese python ever captured in Florida, officials said.
Process to customize molecules does double duty
Inspired by your liver and activated by light, a chemical process developed in labs at Rice University and in China shows promise for drug design and the development of unique materials.
What did Megalodon eat? Anything it wanted -- including other predators.

Megalodon sharks, which went extinct about 3 million years ago, were three times longer than modern great white sharks and were apex predators at highest trophic level ever measured. Researchers used the traces of nitrogen trapped in shark tooth enamel to calculate the trophic levels of the prehistoric predators.

Researchers recently turned to pottery to tease apart the navigational history of the Caribbean, analyzing the composition of 96 fired clay fragments across 11 islands. The study was conducted in the Greater Antilles and marks the first time that pottery artifacts from the Lucayan Islands -- The Bahamas plus the Turks and Caicos Islands -- have been analyzed to determine their elemental...

A new statistical tool for predicting protein function could help with tasks ranging from producing biofuels to improving crops to developing new disease treatments. Not only could it help with the difficult job of altering proteins in practically useful ways, but it also works by methods that are fully interpretable -- an advantage over conventional AI.
Blood test developed to predict liver cancer risk

An estimated one-quarter of adults in the U.S. have nonalcoholic fatty liver disease (NAFLD), an excess of fat in liver cells that can cause chronic inflammation and liver damage, increasing the risk of liver cancer. Now researchers have developed a simple blood test to predict which NAFLD patients are most likely to develop liver cancer.

Chemists developed a method to add two fragments to an alkene molecule in a single process. The discovery could simplify drug and materials design.
Indigenous communities used the Caribbean Sea as an aquatic highway
With some 7,000 islands and cays and a 7,000-year history of human habitation, the Caribbean Sea is practically synonymous with maritime travel. The very word "canoe" is derived from the term "kana:wa," used by the Indigenous Arawakans of the Caribbean to describe their dugout vessels.
Timing is everything for weed management
Farmers can tailor their efforts to control weeds more effectively by pinpointing when a particular weed will emerge, according to a new Cornell University study.
Theoretical calculations predicted now-confirmed tetraneutron, an exotic state of matter
James Vary has been waiting for nuclear physics experiments to confirm the reality of a "tetraneutron" that he and his colleagues theorized, predicted and first announced during a presentation in the summer of 2014, followed by a research paper in the fall of 2016.
