Phys.org / Birth rates are declining in most of the world—here's why it really matters
Birth rates have been declining worldwide since the peak of the post-Second World War baby boom. Birth rates have now reached below replacement in most of the world, including Australia. Put simply, populations on average ...
Phys.org / SpaceX IPO set for liftoff in record market debut
Elon Musk's SpaceX was set to begin trading on the Nasdaq exchange Friday, with the biggest initial public offering in history expected to make the polarizing entrepreneur the world's first trillionaire.
Phys.org / Physicists observe synchronized quantum dance of excitons and phonons
An international team of researchers has reported a major advance in understanding quantum dynamics in semiconductor materials. They directly observed how excitons and phonons evolve together in perovskite nanocrystals, revealing ...
Medical Xpress / Sleep and exercise may curb heart risk from mutant white blood cells
Healthy sleep and regular exercise can work to counteract genetic mutations in white blood cells that are associated with cardiovascular disease and are most common among older people, Mount Sinai researchers have found. ...
Phys.org / How bacteria organize themselves to 'hitchhike' across large distances
While scientists have studied how bacteria move toward food using a chemical radar known as chemotaxis, they have only watched single species swim in isolated environments over distances of only a few centimeters.
Phys.org / What happens when cartoon villains have an accent? Research reveals impact on kids
When kids watch cartoons, they're absorbing much more than a plot. Thanks to the use of foreign accents in shows, they're also learning a shorthand for moral character, new research from the University of Toronto Mississauga ...
Phys.org / Antibiotics drive resistance in waterways—even after they break down
Antibiotics continue to drive resistance in bacteria, even after they are broken down in wastewater treatment plants and discharged into rivers and seas, new research published on World Oceans Day has shown for the first ...
Phys.org / AI model 'hears' Bryde's whale calls in seismic data from South China Sea
Researchers have repurposed an AI model designed for visual identification tasks to detect Bryde's whale calls contained within seismic data collected in the South China Sea. The detection system precisely identified calls ...
Phys.org / Why plastic lingers: Water chemistry slows nature's cleanup
Scientists have long known that sunlight helps break down plastic. So, why do plastic products linger for decades and even centuries in rivers, lakes, and oceans—even when bathed in direct sunlight? Northwestern University ...
Phys.org / Algorithm visualizes how cells 'talk' to one another across tissue and time
People communicate with each other, sometimes face to face, sometimes with a text message or phone call. Cells also communicate with each other, sometimes by touching and sometimes by sending signals across space and time. ...
Phys.org / Silent volcanic gas buildup revealed six months before La Palma eruption
Researchers at Geosciences Barcelona (GEO3BCN-CSIC) have developed a novel way to monitor the silent accumulation of volcanic gases beneath Earth's surface using seismic ambient noise. The results could significantly improve ...
Medical Xpress / New study shows metformin given during acute COVID-19 infection reduced risk of clinician-diagnosed long COVID by 50%
New findings from the ACTIV-6 randomized clinical trial provide important confirmation of prior clinical trial results that metformin, a widely available and inexpensive medication with an established safety record, reduced ...
