The key to weathering rapid sea-level rise may lie in a Massachusetts salt marsh

A team of researchers led by Brian Yellen, research professor of earth, geographic and climate sciences at the University of Massachusetts Amherst, recently announced in the Journal of Geophysical Research: Earth Surface that salt marshes, critical habitats threatened by rapid sea-level rise, may in fact thrive despite higher water levels. The key factor that determines whether salt marshes...

New tool uses ultrasound 'tornado' to break down blood clots

Researchers have developed a new tool and technique that uses 'vortex ultrasound' -- a sort of ultrasonic tornado -- to break down blood clots in the brain. The new approach worked more quickly than existing techniques to eliminate clots formed in an in vitro model of cerebral venous sinus thrombosis (CVST).

Targeted test for antibiotic resistance in clinical Enterobacter species

Bacteria of the genus Enterobacter are among the most dangerous bacteria associated with hospital infections worldwide. Some of their representatives are highly resistant to commonly used antibiotics, so that the reserve antibiotic colistin is increasingly used as a last resort therapy option. To avoid unnecessary reliance on colistin and risk increasing resistance, bacteria are tested for...

New discovery: Endangered Amami rabbit disperses seeds for non-photosynthetic plant

Seed dispersal is an essential process for the evolution and ecology of terrestrial plants, making discoveries of uncommon seed dispersal agents particularly interesting. Scientists now reveal that the Amami rabbit (Pentalagus furnessi) is a major seed dispersal agent for the non-photosynthetic plant Balanophora yuwanensis. To the best of our knowledge, this is the first known instance of rabbits...

Agriculture linked to changes in age-independent mortality in North America

The transition to agriculture from hunting and gathering in pre-colonial North America led to changes in age-independent mortality, or mortality caused by factors that are not associated with age, according to a new study. The team found that the intensification of crop use occurred in two phases, the first of which led to a decline in human age-independent mortality, while the second is...

Our memory for objects might be better than we think

The next time you're struggling to remember exactly where you left your keys, parked your car or put down your glasses, don't necessarily give up on your memory completely. Previous research has shown that, if people are shown a large number of objects, they are very good at subsequently remembering which objects they have seen.

Darkest view ever of interstellar ices

Astronomers used observations from the James Webb Space Telescope (JWST) to achieve the darkest ever view of a dense interstellar cloud. These observations have revealed the composition of a virtual treasure chest of ices from the early universe, providing new insights into the chemical processes of one of the coldest, darkest places in the universe as well as the origins of the molecules that...

A few pieces of good news on climate change (and a reality check)

When it comes to climate, the picture can look bleak.  Emissions of the greenhouse gases that cause climate change reached a new peak in 2022, according to early estimates. And climate disasters seem to be hitting at a breakneck pace. In 2022, the world experienced record heat waves in China and Europe, and devastating floods in Pakistan killed over 1,000 people and displaced...
