When the Swiss and Italian governments got together to redraw the alpine border that divides the two countries last year, due to rapidly retreating glaciers, it put into stark focus a challenge that is expected to face many nations that have natural structures that mark territories.

A severe brain injury can leave patients unresponsive to stimuli, but they may be more aware than we realize. A new study of brain activity has shown that up to a quarter of unresponsive patients may exhibit “hidden consciousness.”

While cochlear implants do allow some deaf people to hear, they also incorporate potentially problematic external components located on the side of the head. That could soon change, however, thanks to an experimental new implantable microphone.

The first study to measure the concentration of metals in tampons has found that several brands contain concerning amounts of lead, arsenic and cadmium. More research is needed to determine whether the presence of these toxic metals poses a health risk.

Measles is on the rise, attributable to the anti-vaccination movement and exacerbated by the COVID-19 pandemic. Researchers have identified a new way of tackling one of the most contagious viruses around, offering protection for those at greatest risk.

For low-birth-weight (LBW) babies, skin-to-skin contact with their mother can literally be a lifesaver. A new high-tech necklace ensures that they get enough of that snuggling, while also providing essential data on their vital signs.

Even brief periods of anger caused by triggering memories can negatively impact our blood vessels' ability to relax. That's the finding of a new study that could have implications on how we look at heart attack and stroke risk.

Adding rat stem cells to a mouse embryo resulted in a ‘hybrid brain’ in which the rat cells stepped in to restore function when the mouse’s sense of smell was removed. The new research represents a step forward in regenerative medicine.

A robot that senses when a human is about to smile and simultaneously responds with one of its own could represent a big step towards developing robots with enhanced communication skills more conducive to building human trust, a new study suggests.

In an effort to mitigate human-caused climate warming, scientists are focused on ways to remove carbon dioxide from the atmosphere. One of the more novel ways to do this has just been announced by scientists employing a smart dual-method process.

Researchers have revealed how regular ketamine use produces divergent changes in parts of the brain that produce the ‘feel-good’ neurotransmitter, dopamine. The discovery could have significant implications for the treatment of mental illness.

Scientists have found that a “superatomic” material is the fastest and most efficient semiconductor ever. Taking advantage of a tortoise-and-hare mechanism, the new material can transport energy much faster than silicon.
