Forty-five years ago Sunday, Apollo 11's Neil Armstrong and Buzz Aldrin became the first humans to set foot on another world. Armstrong's "one small step... one giant leap" on the dusty lunar surface July 20, 1969, still stirs hearts. You can join the celebration, without needing to travel to the launch site at Florida's Kennedy Space Center.
Ultrafast X-ray laser research has provided scientists with a snapshot of a fundamental molecular phenomenon. The finding sheds new light on microscopic electron motion in molecules.
In an experiment, a new network-management system reduced the average queue length of routers in a Facebook data center by 99.6 percent— virtually doing away with queues.
A new study has found that eye patterns concentrate on a stranger’s face if the viewer sees that person as a potential partner in romantic love, but the viewer gazes more at the other person’s body if he or she is feeling sexual desire. That automatic judgment can occur in as little as half a second, producing different gaze patterns.
Feeding a growing human population without increasing stresses on Earth’s strained land and water resources may seem like an impossible challenge. But, according to a new report, focusing efforts to improve food systems on specific regions, crops and actions could make it possible to meet the basic needs of 3 billion more people and decrease agriculture’s environmental footprint.
Physicists are working to bring the theory that parallel universes exist— called the multiverse hypothesis— firmly into the realm of testable science.
A space probe aiming to become the first to land on a comet has taken images that appear to show its target could actually be two separate lumps of rock and ice, scientists say.
Researchers have taken a broad look at changes in gene activity in response to diet in the Western honey bee. They found significant differences occur depending on what the bees eat.
A drug that is commonly used for arthritis has been shown to slow the progression of Alzheimer’s. A small randomized control study tested the drug Etanercept on patients with mild to moderate Alzheimer’s. Results showed that patients who were given Etanercept did not get any worse during the six month follow up compared to those on the placebo, who did decline.
A biochemist’s discovery of a class of anti-viral small molecules that target the function of a virus DNA hidden in the infected livers of hepatitis B patients may lead to a cure for this viral infection that kills more than 600,000 people annually.
Researchers have a better understanding of the asteroid Vesta and its internal structure, thanks to numerical simulations and data from the space mission Dawn. Their findings question contemporary models of rocky planet formation, including that of Earth.
In mice with diet-induced diabetes— the equivalent of type 2 diabetes in humans— a single injection of the protein FGF1 is enough to restore blood sugar levels to a healthy range for more than two days. The discovery could lead to a new generation of safer, more effective diabetes drugs.
Mathematical equations can make Internet communication via computer, mobile phone or satellite many times faster and more secure than today. Results from new software are attracting attention in the international technology media.
Genetics could be the key to explaining nations’ levels of happiness. Economists have looked at why certain countries top the world happiness rankings. They found that, the closer a nation is to the genetic makeup of Denmark, the happier that country is.
The same federal scientist who recently found forgotten samples of smallpox at a federal lab also uncovered more than 300 additional vials, many bearing the names of highly contagious viruses and bacteria such as dengue, influenza and rickettsia.
