AI companions are becoming increasingly popular, with millions of users forming deep connections with persona-based chatbots and simulated AI partners. But if you're considering leaning on an AI companion for emotional support, ...
Phys.org / Total eclipse gives scientists chance to probe sun's mysteries
Scientists plan to use a total solar eclipse that will be visible in Spain next week as a rare chance to learn more about the stormy, unpredictable nature of our star.
Medical Xpress / New model maps where HIV is concentrated and the disease is more advanced
A new biostatistical modeling approach has the potential to support health decisions by pinpointing where HIV is concentrated and where people living with HIV are showing signs of severe immune suppression or delayed treatment. ...
Medical Xpress / Wildfire smoke sends more Oregonians to emergency rooms
Days of poor air quality from thick wildfire smoke are pushing more Oregonians into emergency rooms and urgent care clinics, state health officials say.
Medical Xpress / From planning to action: Fundamental insights on movement planning in the brain
When the signal sounds, all the runners push off from their starting blocks and set off sprinting. We can act within fractions of a second because we plan movements in our brains in advance, before carrying them out. At the ...
Medical Xpress / Hidden DNA regulators may drive neurodevelopmental disorders by reducing FOXG1 protein
A new study from the laboratory of Gemma Carvill, Ph.D., associate professor in the Ken and Ruth Davee Department of Neurology's Division of Epilepsy and Clinical Neurophysiology, has uncovered variants in noncoding regulatory ...
Phys.org / New museum find shows nature can't stop inventing seahorses
At first glance, it looks exactly like a seahorse. It has the same horse-shaped head tilted down from the body, the same curled, grasping tail and, in the males, a fully enclosed pouch for brooding the young.
Phys.org / New molecule class creates hardy, drought tolerant plants
As climate change causes water scarcity and temperatures to rise, crops around the world are feeling the heat. How can we prevent severe crop losses in these relentlessly sweltering conditions? An international research team ...
Phys.org / Avalanche cracks may appear globally supersonic while remaining locally subsonic
Can a crack be supersonic? Can the fracture that triggers an avalanche propagate faster than the limiting velocity predicted by classical fracture mechanics? The question remains the subject of debate within the scientific ...
Phys.org / Officials will not release cool water from a Colorado River reservoir to protect threatened fish
Federal officials said Thursday they will not release cool water this year from one of the Colorado River's major reservoirs, which would have protected a threatened native fish downstream but put more strain on already struggling ...
Medical Xpress / Three proteins help organs tailor shared circadian clock to their individual needs, mouse study finds
LMU researchers have elucidated how different organs adapt the same clock machinery to regulate their individual needs over the course of a day.
Medical Xpress / Early split in brain precursors creates two neuron lineages, mouse study finds
The cerebral cortex is densely packed with different nerve cells that enable us to perceive, think and act. Yet how these cell types arise as the brain develops is still not fully understood. Irene Varela-Martínez, a postdoctoral ...
