People who experienced a disaster had a higher prevalence of problem alcohol use in the years after the disaster, and the rates of problem alcohol use increased over time. A study of nuclear power plant workers who experienced a disaster found that those who were exposed to life-threatening danger, discrimination, death of a colleague, or major property loss had an increased prevalence of problem alcohol use. However, for some, the increase in problem drinking did not occur until more than a year after the disaster. The study’s findings, recently published in Alcohol: Clinical and Experimental Research, point to the prolonged impacts on people who experience disaster and the importance of providing long-term monitoring and support beyond the immediate aftermath of the disaster.

The idea that people make decisions based on social context is not a new one in neural economic games. But now, for the first time, researchers publishing in Nature Human Behavior show the impact of the social context may spring from the dynamic interactions of dopamine and serotonin. Researchers built carbon-fiber electrodes that were implanted in patients receiving Deep Brain Stimulation surgery. The method allows researchers to measure more than one neurotransmitter at a time, revealing a dance that has never been seen before

About eight million people live with Type 1 diabetes (T1D) worldwide, a chronic autoimmune condition in which the body attacks and destroys its own insulin-producing β-cells (pronounced “beta”) in the pancreas, leading to a lack of insulin and inability to regulate blood sugar. It’s not known why the body suddenly perceives its own β-cells as the enemy; some lines of evidence suggest environmental factors such as viral infections may trigger the onset of T1D, others suggest genetics may also play some role. Groundbreaking research by investigators at Joslin Diabetes Center sheds new light on the specific changes β-cells go through at the onset of T1D. Their findings—published in Nature Cell Biology—offer new avenues for targeted interventions for the chronic autoimmune condition.

People who tend to act rashly when upset may be more likely to expect alcohol to affect them—both positively and negatively—and may be more likely to want to drink to improve their mood. Mood changes, whether positive, negative, or neutral, did not alter these beliefs, according to a study of college students published in a recent issue of Alcohol: Clinical and Experimental Research. This study helps to inform further research on the relationship between impulsivity and alcohol misuse.

A study of more than 60,000 specimens of snakes and lizards worldwide reveals that snakes stand out alone in the evolution of reptiles. The team of scientists discovered that snakes evolved incredibly fast, as their ancestors shed limbs and adapted on multiple levels to live and spread out into thousands of species of snakes over 66 million years, up to today.

Recent developments in cancer research have highlighted the vital role of the immune system, particularly in the notable successes of cancer immunotherapy. Now, a paradigm-shifting study led by researchers at the Icahn School of Medicine at Mount Sinai in New York in collaboration with the University of Helsinki and Massachusetts General Hospital sheds light on how variations in immune genetics influence lung cancer risk, potentially paving the way for enhanced prevention strategies and screening. The findings were described in the February 22 online issue of Science.

The findings out of Dana-Farber Cancer Institute highlight that the mechanisms of immune modulation are different in patients treated with immunotherapy and anti-angiogenic combinations. The results also point to the role of tumor biology in the diversity and actions of tumor-infiltrating immune cells brought into action by these treatments. The findings might be important for predicting or understanding treatment outcomes in advanced kidney cancer.

A new analysis method can detect pathogens in blood samples faster and more accurately than blood cultures, which are the current state of the art for infection diagnosis. The new method, called digital DNA melting analysis, can produce results in under six hours, whereas culture typically requires 15 hours to several days, depending on the pathogen.

Despite the technological advances keeping meat fresh for as long as possible, certain aging processes are unavoidable. Adenosine triphosphate is a molecule produced by breathing and responsible for providing energy to cells. When an animal stops breathing, ATP synthesis also stops, and the existing molecules decompose into acid, diminishing first flavor and then safety. Hypoxanthine and xanthine are intermediate steps in this transition. Assessing their prevalence in meat indicates its freshness. In AIP Advances, researchers developed a biosensor using graphene electrodes modified by zinc oxide nanoparticles to measure HXA. The team demonstrated the sensor’s efficacy on pork meat.

Service members who have had a moderate, severe, or penetrating traumatic brain injury, or TBI, are at a greater risk for subsequently developing brain cancer, according to a collaborative study led by researchers at the Uniformed Services University (USU) published February 15, 2024, in JAMA Open Network. On the other hand, those who have suffered mild TBI, or concussion – which is much more common – may not be associated with later brain cancer diagnoses, the study finds.
