Medical Xpress / Still moments reveal how the brain links distant places during learning
When the brain encodes and consolidates memories, it often connects related experiences that happened in different places and at different times. The neural processes that contribute to linking different meaningful experiences, ...
Medical Xpress / No live animal testing needed: Lab-grown airway organoids reveal viral infection in wildlife species
Experimental infections, where a pathogen is introduced into the host body to see its effects in action, are considered the gold standard for assessing how vulnerable a host is, offering clear insights into how a pathogen ...
Phys.org / Bacterial defense system builds DNA in unexpected new way to stop viruses
Scientists at Stanford University have discovered that DRT3, a unique defense system found in bacteria, creates DNA to protect against viral infections. DRT3 is made up of two different enzymes called reverse transcriptases, ...
Phys.org / Why Kamchatka's magnitude 8.8 earthquake brought a smaller tsunami—and where risk may remain
On July 29, 2025, a magnitude 8.8 earthquake occurred near the Kamchatka Peninsula. It was so powerful that it ranks as the sixth-largest earthquake ever recorded by modern instruments. Using this giant earthquake as a learning ...
Phys.org / Slower access, faster chemistry: Nanoreactor design improves catalysis by balancing molecular flow
A new study by a team at Tohoku University, published in Chemical Engineering Journal, has shown that more isn't always better when it comes to nanoscale chemical reactions. One might think that giving reactants completely ...
Science X / Personalized brain-training approach goes after one of depression's hardest-to-break loops
Depression is a debilitating mental health disorder characterized by persistent low mood, a loss of interest in everyday activities, repetitive negative thinking and possible changes in appetite and/or sleeping patterns. ...
Medical Xpress / Stopping and restarting certain GLP-1s to lose weight may make the drug less effective
Inconsistent use of some GLP-1 weight-loss medications, like Ozempic and Wegovy, may significantly lessen their effectiveness, according to a new preclinical study from researchers at the Perelman School of Medicine at the ...
Phys.org / The way a cell fails to divide after copying its DNA can determine its fate
Cell division is one of the most fundamental and complex processes underpinning life. In human cells, thousands of molecules coordinate with one another in highly precise steps, all within a fraction of a second. But things ...
Phys.org / How photosynthetic bacteria pass light along: Two major energy pathways identified
RIKEN researchers have found out how light energy harvested by pigments besides chlorophyll is transferred to the molecular site where photosynthesis occurs in cyanobacteria. The work is published in the journal Plant and ...
Medical Xpress / FDA approves once-daily Idvynso tablet for treating HIV
The U.S. Food and Drug Administration has approved Merck's Idvynso (doravirine/islatravir), a new, once-daily, two-drug single tablet for the treatment of HIV-1 infection in adults to replace the current antiretroviral regimen ...
Medical Xpress / Excessive cholesterol in astrocytes linked to cognitive decline in Alzheimer's mice
Alzheimer's disease (AD) is a neurodegenerative disorder that leads to progressive memory loss and a decline in mental functions. Several past studies have linked this disease to the accumulation of the protein amyloid-β ...
Science X / The keyboard trap: Why your best arguments are failing online
While 84% of people prefer to type out a disagreement, new research involving 1,842 conversations reveals that the "safer" choice is actually fueling social friction. In an era of digital flame wars and rising political partisanship, ...
