NEW JERSEY, March 27, 2025 — The American Heart Association and The Giants Foundation, the nonprofit organization of the New York Giants, gathered representatives from 12 local schools for cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) training on March 20 at MetLife Stadium. According to American Heart Association data, nearly 9 out of 10 people who experience cardiac arrest outside of a hospital die, in part because they do not receive immediate CPR more than half of the time. CPR, especially if performed immediately, can double or triple a person’s chance of survival. “Early recognition and action in a cardiac emergency ...

When monitoring the health of mammal populations, scientists often use camera traps to observe the animals in their habitats.  But weasels are so sneaky they’re rarely caught on camera – leaving scientists with questions about this population of predators. “We’re a little worried about the weasels,” says Roland Kays, a research professor at North Carolina State University and scientist at the N.C. Museum of Natural Sciences. “We don’t see them very often, but it’s ...

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 ...

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 ...

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 ...

Reston, VA (March 28, 2025)—A novel PET imaging approach can effectively quantify a key enzyme associated with brain inflammation, according to research published in the March issue of The Journal of Nuclear Medicine. The first-in-human study, which imaged the COX-2 enzyme, offers a never-before-seen view of inflammation in the brain, opening the door for COX-2 PET imaging to be used in clinical and research settings for various brain disorders. COX-2 is an enzyme in the brain that can be markedly upregulated by inflammatory stimuli and neuroexcitation. Researchers say that the density of COX-2 in the brain may be a biomarker and effect of inflammation, ...

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 ...
