How the failure of two dams amplified the Derna Flood tragedy
2025-03-28
A new study reveals that the devastating 2023 flood in Derna, Libya, was not merely the result of extreme rainfall but was drastically intensified by a major design shortcoming and its resulting collapse of two embankment dams. Through advanced hydrological modeling and satellite data analysis, researchers found that while Storm Daniel brought heavy rainfall, the catastrophe stemmed from dam failures and flawed risk assessment and communication—amplifying the destruction nearly twentyfold. The findings highlight the urgent need for improved flood mitigation strategies, especially in dryland regions where high uncertainty ...

Brain channels ‘stopped in time’ reveal chemical flow that enables learning and thinking
2025-03-28
FOR IMMEDIATE RELEASE
In an effort to understand how brain cells exchange chemical messages, scientists say they have successfully used a highly specialized microscope to capture more precise details of how one of the most common signaling molecules, glutamate, opens a channel and allows a flood of charged particles to enter. The finding, which resulted from a study led by Johns Hopkins Medicine researchers, could advance the development of new drugs that block or open such signaling channels to treat conditions as varied as epilepsy and some intellectual disorders.
A report on the experiments, funded by the National ...
PET imaging confirms direct involvement of dopamine in cognitive flexibility
2025-03-28
Reston, VA (March 16, 2025)—For the first time, scientists have confirmed a neurobiochemical link between dopamine and cognitive flexibility, according to new research published in the March issue of The Journal of Nuclear Medicine. PET imaging shows that the brain increases dopamine production when completing cognitively demanding tasks, and that the more dopamine released, the more efficiently the tasks are completed. Armed with this information, physicians may soon be able to develop more precise treatment strategies for neurological and psychiatric disorders.
Cognitive flexibility is the ability to adapt one’s thinking and behavior appropriately to ...
Understanding the immune response to a persistent pathogen
2025-03-28
Most humans have long-lived infections in various tissues—including in the nervous system—that typically do not result in disease. The microbes associated with these infections enter a latent stage during which they quietly hide in cells, playing the long game to evade capture and ensure their own survival. But a lack of natural models to study these quiescent stages has led to gaps in scientists’ understanding of how latency contributes to pathogen persistence and whether these stages can be targeted by the immune system.
Now, a team led by University of Pennsylvania School of Veterinary Medicine researchers ...

Genes may influence our enjoyment of music
2025-03-28
Music is central to human emotion and culture. Does our ability to enjoy music have a biological basis? A genetic twin study, published in Nature Communications, shows that music enjoyment is partly heritable. An international team led by scientists from the Max Planck Institute for Psycholinguistics in Nijmegen, the Netherlands, uncovered genetic factors that influence the degree of music enjoyment, which were partly distinct from genes influencing general enjoyment of rewarding experiences or musical ability.
Music plays an important role in human emotion, social bonding, and cultural expression. As Darwin already noted, music "must ...

Fatty acids promote immune suppression and therapy resistance in triple negative breast cancer
2025-03-28
HOUSTON – (March 28, 2025) – A new study published in the journal Immunity reveals a mechanism that allows triple negative breast cancer (TNBC) to develop resistance to therapy. Researchers at Baylor College of Medicine showed that lipid accumulation in tumor cells and nearby immune cells promotes immune suppression, but disrupting lipid formulation reverses treatment resistance and the immunosuppressive microenvironment.
Standard-of-care treatment for TNBC includes chemotherapy and immunotherapy. However, some initially responsive tumors still develop recurrences. Researchers studied mouse models and found that TNBC cells that survived treatment accumulated ...
Intermittent fasting increases sex drive in male mice: an approach for low libido in humans?
2025-03-28
Long-term fasting in 24-hour cycles increases the sex drive of male mice by lowering the concentration of the neurotransmitter serotonin in the brain. This effect is linked to a diet-induced deficiency of the precursor substance tryptophan – an amino acid that must be obtained through food. Researchers from DZNE report on this in the journal Cell Metabolism, together with a Chinese team from Qingdao University and the University of Health and Rehabilitation Sciences. They suggest that similar mechanisms may exist in humans and view fasting as a potential approach for treating unwanted loss of sexual desire.
Fasting ...

New approach makes one type of clean fuel production 66% more efficient
2025-03-28
COLUMBUS, Ohio – Researchers have uncovered a more efficient way to turn carbon dioxide into methanol, a type of alcohol that can serve as a cleaner alternative fuel.
In the lab, synthesizing methanol can be extremely difficult, due to the extremely complex reaction pathway needed to select for it. Previous attempts by the same team to manufacture this valuable liquid fuel from carbon dioxide have used a combination of cobalt phthalocyanine (CoPc) molecules and electricity, but this method is inefficient as only about 30% of the carbon dioxide is converted to methanol.

New approach could treat anthrax beyond the “point of no return”
2025-03-28
Anthrax, an infectious disease caused by the bacterium Bacillus anthracis, is often treatable in its early stages. But once the disease has progressed beyond the “point of no return” after just a few days, patients are almost certainly doomed.
In a new Nature Microbiology study, University of Pittsburgh researchers show that a cocktail of growth factors reversed would-be lethal cell damage in mice with anthrax, suggesting that this approach could be adapted for use in patients beyond the brink.
“While only a few people die from anthrax in the United States each year, there is always the concern ...
