New research has provided the first evidence that reptiles could be capable of social learning through imitation. The ability to acquire new skills through the “true imitation” of others’ behavior was thought to be unique to humans and advanced primates, such as chimpanzees.
Droplets are simple spheres of fluid, not normally considered capable of doing anything on their own. But now, researchers have made droplets of alcohol move through water. In the future, such moving droplets may deliver medicines.
By combining a pair of solar cells made with a mineral called perovskite and low cost electrodes, scientists have obtained a 12.3 percent conversion efficiency from solar energy to hydrogen, a record using earth-abundant materials as opposed to rare metals.
The International Space Station has been called a stepping stone to other worlds. NASA hasn't forgotten, however, that the behemoth space station is also on the doorstep of Earth.
Scientists have discovered how to control the limbs of a completely paralyzed rat in real time to help it walk again. Building on earlier work in rats, this new breakthrough is part of a more general therapy that could one day be implemented in rehabilitation programs for people with spinal cord injury. Clinical trials could start as early as next summer.
Antibiotics revolutionized health care in the early 20th century, helping kill bacteria that once killed thousands of people. But bacteria are constantly outsmarting science, and new strains of antibiotic-resistant bacteria are popping up more frequently.
It's the first day of autumn, and the telltale signs are here: crisp weather, pumpkin spice lattes and, most importantly, the leaves are changing colors.
Researchers have equipped a robot with a novel tactile sensor that lets it grasp a USB cable draped freely over a hook and insert it into a USB port. The sensor is small enough to fit on a robot’s gripper and its processing algorithm is fast, so it can give the robot feedback in real time.
Dogs generally seem to be cheerful, happy-go-lucky characters, so you might expect that they would have an optimistic outlook on life. But, some dogs are distinctly more pessimistic than others.
Cephalopods are able to change both the color and texture of their skin within seconds to blend into their surroundings— a capability that engineers have long struggled to duplicate in synthetic materials. Now, a team has come closer than ever to achieving that goal, creating a flexible material that can change its color or fluorescence and its texture at the same time, on demand, by remote control.
A new study into meat tenderness could refine the way people cook steak. Researchers conducted studies using microscopes to see what happens to meat cells while being cooked. They found that meat shrinks while cooking not once but twice.
By now, we've got all the details about Apple's latest iPhone. But what do you really know about the guts of the iPhone 6, or any smartphone for that matter?
Researchers have developed an algorithm for bounding that they’ve successfully implemented in a robotic cheetah— a sleek, four-legged assemblage of gears, batteries and electric motors that weighs about as much as its feline counterpart. The team recently took the robot for a test run where it bounded across grass at a steady clip.
Researchers have identified a mechanism by which wrinkles may have formed in ancient rocks. Based on this mechanism, they posit that such fossilized features may be a vestige of microbial presence— in other words, where there are wrinkles, there must have been life.
Astronauts are studying how fires burn in microgravity and how to put them out. It's a basic safety issue: if a fire ever breaks out onboard a spacecraft, astronauts need to be able to control it.
The increasing acidification of ocean waters caused by rising atmospheric CO2 levels could rob sharks of their ability to sense the smell of food, a new study suggests. Elevated CO2 levels impaired the odor-tracking behavior of the smooth dogfish, a shark whose range includes the Atlantic Ocean off the eastern U.S.
