More than a decade ago, Ralph Hollis invented the ballbot, an elegantly simple robot whose tall, thin body glides atop a sphere slightly smaller than a bowling ball.
Scientists have proposed a space observatory that would have a primary mirror with a diameter of 100 meters (328 feet)—40 times larger than Hubble’s.
The processing power of standard computers is likely to reach its maximum in the next 10 to 25 years.
About 150 million years ago, snakes roamed about on well-developed legs. Now researchers say a trio of mutations in a genetic switch are why those legs eventually disappeared.
Halloween is a chance to seek out the spooky, as well as the gross and horrifying. We enjoy the emotional rush—free of any actual danger—from both, says Daniel Kelly.
Scientists have linked mutations in a single gene to autism in people who have a rare tumor syndrome typically diagnosed in childhood.
Doctors are more likely to prescribe growth hormones for a child who does not meet federal guidelines for the therapy if the child’s family requests it or if the physician believes in its intangible benefits, such as the patient’s emotional well-being, new research finds.
Scientists are smashing metallic micro-cubes to make them ultra-strong and tough by rearranging their nanostructures upon impact.
Only a small fraction of fast-food eaters—as little as 8 percent—are likely to be swayed by calorie counts on menus to make healthy choices, say researchers.
Marks on teeth of a Homo habilis fossil that date back 1.8 million years could be the earliest known evidence of right-handedness.
Computer scientists have created a new system for mobile users to quickly determine their location indoors without communicating with the cloud, networks, or other devices.
Efforts are underway to redesign the internet so it can handle billions of mobile devices and smart gadgets.
New research identifies ways to help people who don’t gel with the company’s culture stay engaged and become more productive.
Archaeologists have conducted pioneering analysis on historic ivory, revealing where East African elephants roamed and where they were hunted in the 19th century.
Numerous studies have found that heavy alcohol use—by the victim and/or perpetrator—is a factor in more than half of sexual assaults on college campuses.
Malicious software is hiding in the cloud, and it may be very difficult to identify, new research finds.
Biomedical engineers have harvested genes for ion channels from bacteria that, with a few tweaks, can create and enhance electrical signaling in human cells, making the cells more electrically excitable.
The discovery of two massive companions around one star in a close binary system—one so-called giant planet and one brown dwarf, or “failed star”—suggests that everything we know about the formation of solar systems might be wrong, say University of Florida astronomy professor Jian Ge and postdoctoral researcher Bo Ma.
Despite being relatively rare, African-American Republicans are diverse in their political thinking and reasons for being part of the GOP.
Virtual reality can take us where our imaginations falter: a world where human-caused carbon-dioxide emissions haven’t been curbed.
