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.
Scientists have found that birds display superior judgment of their body width compared to humans. This discovery came from research intended to help design autonomous aircraft navigation systems.
Shellfish such as mussels and barnacles secrete very sticky proteins that help them cling to rocks or ship hulls, even underwater. Inspired by these natural adhesives, a team of engineers has designed new materials that could be used to repair ships or help heal wounds and surgical incisions.
Contrary to what was previously thought, newborn immune T cells may have the ability to trigger an inflammatory response to bacteria, according to a new study. Although their immune system works very differently to that of adults, babies may still be able to mount a strong immune defense.
Physicists have succeeded in teleporting the quantum state of a photon to a crystal over 25 kilometers of optical fiber. The experiment constitutes a first, and pulverizes the previous record of six kilometers achieved 10 years ago by the same team.
The California State Teachers' Retirement System says it plans to increase its investments in clean energy and technology to $3.7 billion, from $1.4 billion, over the next five years.
Chronic stress can lead to behavioral problems. A team of researchers has discovered an important synaptic mechanism: the activation of a cleaving enzyme, leading to these problems.
The government said Friday it will rewrite sweeping new food safety rules after farmers complained that earlier proposals could hurt business. New proposals by the FDA would make it easier for farmers to meet water quality standards and allow farmers to harvest crops sooner after using raw manure as fertilizer.
A dazzling show of fire and color can make science come alive for young students, but it can also inflict serious and painful injuries, as flash fires in Nevada and Colorado showed this month.
Researchers who found that packing strips of cured pork in the nose of a child who suffers from uncontrollable, life-threatening nosebleeds can stop the hemorrhaging won an Ig Nobel prize last night. Other winners included a team of researchers who wondered if owning a cat was bad for your mental health and Japanese scientists who tested whether banana peels are really slippery.
A multidisciplinary team of scientists are using some of the most advanced X-ray micro Computed Tomography scanners to learn how to design plant roots so they can interact better with soil and capture water and nutrients more efficiently. This non-invasive technology will help them unearth some of the answers to one of the biggest challenges facing the world today— global food security.
It is a cruel world out there, particularly for young animals born into social groups where infanticide occurs. This dark side of evolution is revealed when adults– often males– kill offspring to promote their own genes being passed on, by reducing competition for resources or making females become sexually receptive more quickly.
Most people would describe confidence as an emotion or a feeling. In contrast, scientists have found that confidence is actually a measureable quantity, and not reserved just for humans. A team has identified a brain region in rats whose function is required for the animals to express confidence in their decisions.
