Researchers have uncovered key insights into the dangerous phenomenon of 'river avulsion,' offering a way to predict when and where rivers may suddenly and dramatically change course.
Origami paper sensors could help early detection of infectious diseases in new simple, low-cost test
Researchers have developed an innovative new method for identifying biomarkers in wastewater using origami-paper sensors, enabling the tracking of infectious diseases using the camera in a mobile phone. The new test device is low-cost and fast and could dramatically change how public health measures are directed in any future pandemics.
Genetic tracing at the Huanan Seafood market further supports COVID animal origins
A new study provides a list of the wildlife species present at the market from which SARS-CoV-2, the virus responsible for the COVID-19 pandemic, most likely arose in late 2019. The study is based on a new analysis of metatranscriptomic data released by the Chinese Center for Disease Control and...
A new ventilator-on-a-chip model to study lung damage
Scientists are now able to directly compare the different kinds of injury that mechanical ventilation causes to cells in the lungs. In a new study, using a ventilator-on-a-chip model, researchers found that shear stress from the collapse and reopening of the air sacs is the most injurious type of damage.
Explaining dramatic planet-wide changes after world’s last ‘Snowball Earth’ event
Some of the most dramatic climatic events in our planet's history are 'Snowball Earth' events that happened hundreds of millions of years ago, when almost the entire planet was encased in ice up to 0.6 miles thick. New research provides a more complete picture for how the last Snowball Earth...
Can the MIND diet lower the risk of memory problems later in life?
People whose diet more closely resembles the MIND diet may have a lower risk of cognitive impairment, according to a new study. Results were similar for Black and white participants. These results do not prove that the MIND diet prevents cognitive impairment, they only show an association.
Sea surface temperature record in the southwestern Pacific: Coral colony from Fiji reveals warmest temperatures in over 600 years
The sea surface temperature in the Fijian archipelago in the southwestern Pacific is now at its maximum for more than 600 years. This finding is the result of an international research team's evaluation of a new coral record providing further evidence for unprecedented warming in the western Pacific Ocean. According...
Even marine animals in untouched habitats are at risk from human impacts
Climate change and a range of other human impacts are putting marine animals at risk of extinction -- even those living in almost pristine marine habitats and diverse coastal regions -- reports a new study.
South African rock art possibly inspired by long-extinct species
A mysterious tusked animal depicted in South African rock art might portray an ancient species preserved as fossils in the same region, according to a new study.
‘Scuba-diving’ lizards use bubble to breathe underwater and avoid predators
