​We’ve seen robots that can respond to touch and voice commands, but what about a robot with a sense of taste? A new experimental device is built to explore this possibility, and in its current form can already perform a little taste test to see if its bathwater has been contaminated.​​

New research has added to our understanding of depression by highlighting how certain brain activity may be linked to certain moods, raising the prospect of a biological signature that could one day be used as an indicator of the illness and help those devising new therapies to treat it.

The recent wildfires in California have taken a terrible toll, but it isn't just people who suffered. Two adult female black bears were caught in the conflagration and suffered third degree burns on their paws, which were treated using innovative new, edible bandages made out of fish skins.

Every particle has an antiparticle, which has the opposite charge. But it’s long been theorized that there’s an exception to the rule, with certain particles that are actually their own antiparticles. Now, scientists have found the first strong evidence for what they dub the “angel particle.”

​​We know that plankton are too small to swim on their own, so how do these little drifters get to where they need to go? Seeking answers to this question along with other insights about our oceans, scientists have built underwater robots that mimic plankton behavior.

Predator-prey interactions, like those between vipers and rats, play out countless times every day and are over in an instant, but armed with cutting edge video technologies biologists are now able to observe them in mesmerizing new ways. ​​

Scientists say that what you've been told about cement is not entirely true. Far from being a climate change villain, it actually helps clear a substantial amount of carbon dioxide from the air once it's set.

By analyzing the molecular traces left behind on smartphone displays, scientists have worked out a way to paint pictures of user lifestyles – information that may one day help crime scene investigators close in on a suspect.​​​

Engineers from the University of California, San Diego​ have brought together a couple of nascent technologies that could result in inexpensive and long-lasting electronic devices. The team created a magnetic ink that can print a variety of self-healing components.

Scientists at UCI say that cosmic radiation could cause astronauts on long deep space missions to develop "space brain" with symptoms of dementia. Tests indicate that exposure to high-energy particles cause marked by long-term neurological damage.

Used to make most of our disposable food and beverage containers, polyethylene is produced at a staggering volume of over 100 million metric tons each year, most of which ends up in landfills. Now researchers have devised a way to recycle this waste into usable liquid fuel.

The water within freshwater lakes is regularly turned over by storms in the winter months, distributing oxygen to the lower levels and preserving the ecosystem. But scientists warn global warming might put the brakes on this process and compromise the health of our freshwater resources.
