A bacterium (named PBSase) found in the sea can degrade a plastic (PBS) that otherwise resists microbial breakdown in marine environments

Chaos theory improves understanding of Arctic narwhal behavior, with the aim of helping efforts to protect this vulnerable species.They are one of the most vulnerable Arctic species due to climate change, human activity, and predation by such invasive species as killer whales.

Study shows that Greenland ice sheet may halve in volume by year 3000

Scientists have uncovered a summertime climate pattern in and around the Arctic that could drive co-occurrences of European heatwaves and large-scale wildfires with air pollution over Siberia and subpolar North America

The blast that shook the ionosphere

A hydrogel, a type of soft matter, developed at Hokkaido University successfully reverted cancer cells back to cancer stem cells within 24 hours, in six different human cancer types

Scientists from Japan and the USA have confirmed the presence in meteorites of a key organic molecule which may have been used to build other organic molecules, including some used by life

New insight into the origin of water on Earth

Bio-inspired hydrogel stiffens 1,800-fold into rigid plastic when exposed to heat and softens when cooled, doing the opposite of what polymer-based plastic materials normally do, that could protect motorcyclists and drivers during accidents, inspired by thermophiles from deep sea thermal vents.

Fossil coral records provide new evidence that frequent winter shamals, or dust storms, and a prolonged cold winter season contributed to the collapse of the ancient Akkadian Empire in Mesopotamia.

Fresh look at mysterious Nasca lines in Peru

Scientists have demonstrated for the first time that horses integrate human facial expressions and voice tones to perceive human emotion, regardless of whether the person is familiar or not.

Obesity is a known risk factor for certain types of cancer, including colon, pancreatic and breast cancer

Letting molecular robots swarm like birds

Ants selectively farm aphids for their sweetness: ants manipulate aphid reproduction rates to achieve a specific mix of green and red aphids, maintaining the inferior green aphids which produce the ants' favorite snack.

A new nanosheet of organic polymers developed to prevent the deformation of biological samples, thus enabling high-quality imaging under microscopes.
