'Weird' new planet retains atmosphere despite nearby star's relentless radiation (phys.org)

A rare exoplanet that should have been stripped down to bare rock by its nearby host star’s intense radiation somehow grew a puffy atmosphere instead—the latest in a string of discoveries forcing scientists to rethink theories about how planets age and die in extreme environments....

New vestiges of the first life on Earth discovered in Saudi Arabia (phys.org)

Stromatolites are the earliest geological record of life on Earth. These curious biotic structures are made of algae carpets growing toward the light and precipitating carbonates. After their first appearance 3.48 Ga ago, stromatolites dominated the planet as the sole living carbonate factory for almost three billion years....

Study finds consistent decline in nitrogen oxides emissions from human activities in China since 2020 (phys.org)

Nitrogen oxides (NOx) form aerosols and ozone in the atmosphere and are significant contributors to air pollution and climate change. China is the largest emitter, yet accurate and timely information on NOx emissions in China has been lacking since 2020 due to delays in emissions reporting.

Men with 'toxic masculinity' are more likely to make sexual advances without consent, study finds (phys.org)

A team of researchers, including Binghamton psychology professor Richard Mattson and graduate student Michael Shaw asked men between the ages of 18–25 to respond to hypothetical sexual hookup situations in which a woman responds passively to a sexual advance, meaning the woman does not express any overt verbal or behavioral...

Cultural and linguistic networks of central African hunter–gatherers have ancient origin, study finds (phys.org)

Extensive social networks between different hunter–gatherer groups in the Congo Basin existed long before agriculture arrived in the region. This continent-wide exchange preserved a cultural diversity that evolved thousands of years ago, as researchers from the University of Zurich have shown based on musical instruments,...

New metal-free porous framework materials may have potential for hydrogen storage (phys.org)

Researchers at the University of Liverpool and the University of Southampton have used computational design methods to develop non-metal organic porous framework materials, with potential applications in areas such as catalysis, water capture or hydrogen storage.

The first lithic study of level VI-B at the Mumba site in Tanzania reveals Middle Stone Age industry (phys.org)

Irene Solano Megías, a predoctoral researcher at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), has just published the first techno-typological study of the most ancient lithic industry of level VI-B at the Mumba rockshelter in the journal African Archaeological Review. This site lies in the Lake...
