Toward defining problematic media usage patterns in adolescents

JAMA

2025-04-28
(Press-News.org) About The Article: This Viewpoint proposes an analogous taxonomy for digital media use that identifies patterns of use, irrespective of content, that could be problematic but, at a minimum, should be flagged as warranting further evaluation and potential remediation.

New insight into how the brain switches gears could help Parkinson’s patients

2025-04-28
New USC research offers an unseen insight into how the brain shifts gears. The researchers discovered that our innate ability to make quick changes in motor function are the result of a unique brain mechanism. In the high-stakes world of the NBA, we watch in awe as our favorite player seamlessly switches moves in the blink of an eye. A perfect layup is suddenly defended. The shooter changes course mid-air, passing to an open teammate for a corner three. Humans have a remarkable ability to rapidly switch between different motor actions when life throws us a curveball. You reach to pull open a door but suddenly see you must push to exit. In traffic, you must ...

Dopamine signals when a fear can be forgotten

2025-04-28
Dangers come but dangers also go and when they do, the brain has an “all-clear” signal that teaches it to extinguish its fear. A new study in mice by MIT neuroscientists shows that the signal is the release of dopamine along a specific interregional brain circuit. The research therefore pinpoints a potentially critical mechanism of mental health, restoring calm when it works, but prolonging anxiety or even post-traumatic stress disorder when it doesn’t. “Dopamine is essential to initiate fear extinction,” said Michele Pignatelli di Spinazzola, co-author ...

Anatomy of a “zombie” volcano: investigating the cause of unrest inside Uturuncu

2025-04-28
Images available via the link in the notes section Scientists from China, the UK and the USA have collaborated to analyse the inner workings of Bolivia’s “zombie” volcano, Uturuncu. By combining seismology, physics models and analysis of rock composition, researchers identify the causes of Uturuncu’s unrest, alleviating fears of an imminent eruption. The findings have been published today (28 April) in the journal PNAS. Deep in the Central Andes lies Uturuncu, Bolivia’s “zombie” ...

Some dogs, cats bred to evolve same ‘smushed’ faces

2025-04-28
UNDER EMBARGO UNTIL 3PM ET ON MONDAY, APRIL 28 IN PNAS ITHACA, N.Y. – Through intensive breeding, humans have pushed breeds such as pug dogs and Persian cats to evolve with very similar skulls and “smushed” faces, so they’re more similar to each other than they are to most other dogs or cats.   For the first time, scientists at Cornell University and Washington University have uncovered examples of how selection pressures from breeding cats and dogs have led to “convergence” – the tendency of unrelated animals and plants to evolve similar characteristics under similar environmental conditions. In this case, the researchers found ...

Sexism undermines teams by disrupting emotional synchrony’s role in performance

2025-04-28
UNDER EMBARGO UNTIL 3:00 PM U.S. EDT ON MONDAY, APRIL 28, 2025 In a world where innovation and progress depend on effective teamwork, a new study reveals how sexist behavior within teams sabotages not just individuals, but the very fabric of collaboration. Researchers found that exposure to sexist comments significantly alters how women interact emotionally during teamwork, increasing a key ingredient of successful collaboration: emotional synchrony. Emotional synchrony—shared, temporally aligned facial ...

‘Extremely rare event’: bone analysis suggests ancient echidnas lived in water

2025-04-28
A small bone found 30 years ago at Dinosaur Cove in south eastern Australia could turn what we know about the evolution of echidnas and platypuses on its head. Up until now, the accepted understanding about these egg-laying monotremes – arguably the most unusual mammals on the planet – was that they were both descended from a land-bound ancestor. And while the platypus ancestors became semiaquatic, the echidnas stayed on the land, or so the story went. But following a UNSW-led analysis of the bone – which was discovered ...

Flood risk increasing in Pacific Northwest

2025-04-28
The next great earthquake isn't the only threat to the Pacific Northwest. A powerful earthquake, combined with rising sea levels, could significantly increase flood risks in the Pacific Northwest, impacting thousands of residents and properties in northern California, Oregon, and Washington, according to new Virginia Tech research. A study published this week in the Proceedings of the National Academy of Sciences found that a major earthquake could cause coastal land to sink up to 6.5 feet, expanding the federally designated 1 percent coastal floodplain, an area ...

First synthetic ‘mini prion’ shows how protein misfolding multiplies

2025-04-28
Scientists at Northwestern University and University of California, Santa Barbara have created the first synthetic fragment of tau protein that acts like a prion. The “mini prion” folds and stacks into strands (or fibrils) of misfolded tau proteins, which then transmit their abnormally folded shape to other normal tau proteins. Misfolded, prion-like proteins drive the progression of tauopathies, a group of neurodegenerative diseases — including Alzheimer’s disease — characterized by the ...

BNT162b2 vaccine not only targets COVID-19 virus, but may also help reduce and control innate inflammation

2025-04-28
BNT162b2 vaccine not only targets COVID-19 virus, but may also help reduce and control innate inflammation  New findings suggest the vaccine may reduce the production of pro-inflammatory mediators to bacterial, fungal or viral infections by reprogramming innate immune cells to regulate inflammation Trinity researchers have found that the BNT162b2 COVID-19 vaccine may offer protection beyond its intended, primary target. In a study, recently published in the Clinical Immunology journal, researchers found that the vaccine not only targeted the COVID-19 virus, it also unexpectedly helped to reduce ...

A new method identifies rancid hazelnuts without removing them from the bag

2025-04-28
No more rancid hazelnuts: a research team at the URV has developed a method that can identify nuts that have gone bad due to oxidation. The technique uses infrared light to determine the chemical composition of hazelnuts without even removing them from their shells. The new system overcomes the limitations of traditional methods and makes it possible to identify the condition of all the hazelnuts in a packet in a single analysis, without the need to prepare or destroy the sample. The authors argue that the application of this technology would help to improve packaging techniques and distribution ...
