Expedition 35 Flight Engineers completed a spacewalk at 2:14 p.m. EDT May 11, 2013 to inspect and replace a pump controller box on the International Space Station.
New study helps resolve a dispute over the origins of coral-reef formations.
Researchers reported the observation of a highly fragile and volatile body through a new quantum-mechanical measurement technique.
Platinum nanoparticles on a support made of special mesoporous silicon dioxide can stop ethylene from breaking down fruit.
Edible insects are being promoted as a low-fat, high-protein food for people, pets and livestock.
At seven times the toughness of Kevlar, a silk produced by the Caerostris darwini spider of Madagascar is more robust than any other material. Now, it can be produced at an industrial scale.
A budding effort has begun to track the carbon footprints of megacities, urban hubs with over 10 million people, which are increasingly responsible for human-caused global warming.
Researchers developed a way to introduce precisely four copper ions into quantum dots. This opens up possibilities for fine-tuning their optical properties and producing spectacular colors.
Scientists have identified a protein in the blood of mice and humans that may prove to be the first effective treatment for the form of age-related heart failure that affects millions of Americans.
A new study looking at the genomes of more than 13,000 men identified four new genetic variants associated with an increased risk of testicular cancer.
A breakthrough for direct imaging of exoplanets: ground-based telescopes have begun taking infrared pictures of the planets posing near their stars in family portraits.
Looking at recent laboratory accidents and tragedies, it seems that chemists are still learning lab safety the hard way. By analyzing these students’ mistakes, many chemists can avoid these types of occurrences in the future.
Experiments unearthed clues about which protein signaling molecules are allowed into hollow, hair-like “antennae,” called cilia, that alert cells to critical changes in their environments.
