Medical Xpress / Hippocampal pathways once thought separate converge to integrate 'where' and 'why' in reward processing
New research from the University of Maryland, Baltimore County (UMBC) reveals how two different parts of the brain's memory center team up in a key reward region to help mice—and likely humans—combine memories of places and ...
Medical Xpress / Updated estimates challenge bleak picture of US state gaps in longevity gains
Madison professors suggest longevity gains across all states and regions for people born between 1941 and 2000, in contrast to previous estimates suggesting a century of stagnation or even declines in parts of the South. ...
Medical Xpress / Baby's body clock begins to synchronize with local time while still in utero, study shows
Humans and most other organisms have internal biological clocks that track the daily cycle of sunrise and sunset. These clocks help time our sleep, metabolism and other essential body functions over the course of a day, creating ...
Medical Xpress / COVID-19's lingering shadow: The molecular link between SARS-CoV-2 and lung cancer risk
A new study suggests that COVID-19 may slightly increase the risk of lung cancer by triggering a biological chain reaction in the lungs, driven by the virus's spike protein, that promotes inflammation, scarring, and tumor-friendly ...
Medical Xpress / Could gene edits solve obstacles to treatment for the most common types of cancer?
Since 2017, a personalized immunotherapy called Chimeric Antigen Receptor, or CAR-T cell treatment, has worked wonders to treat patients with blood cancers such as leukemia. But when it comes to treating solid tumor cancers, ...
Medical Xpress / A lung cancer that changes its identity may be hiding in plain sight
A new study co-led by the Institute for Systems Biology (ISB) shows that some lung cancers can change identity as they evolve, shifting from one cancer type to another in ways that may make them more aggressive and harder ...
Medical Xpress / Leukemia cells use a sugar-coated protein to hide from the immune system, study reveals
Leukemia is adept at dodging the immune system, making it resistant to many of the newest generation of cancer immunotherapies. Now, researchers have identified a key part of the cancer's disguise: a protein called CD43 on ...
Medical Xpress / How active play at age 2 can set a decade of activity into motion
The numbers are sobering: nearly 80% of the world's teenagers don't get enough physical activity, according to the World Health Organization. But a new longitudinal study from Université de Montréal suggests the seeds of ...
Medical Xpress / With navigating nematodes, scientists map out how brains implement behaviors
Animal behavior reflects a complex interplay between an animal's brain and its sensory surroundings. Only rarely have scientists been able to discern how actions emerge from this interaction. A new study in Nature Neuroscience ...
Medical Xpress / Reprogramming regulatory T cells could help immunotherapy work in pancreatic cancer
Researchers at Oregon Health & Science University have uncovered a key reason why immunotherapy has largely failed in pancreatic cancer—and identified a promising strategy to overcome that resistance. The study, published ...
Medical Xpress / Hidden skin microbe activity revealed in real time with RNA method
Scientists have long known that our skin is home to vast communities of bacteria, fungi and viruses. But knowing which microbes are present only tells part of the story. What matters just as much is which microbes are active, ...
Medical Xpress / What does it mean to be well? Research delivers building blocks for good mental health
For decades, "mental well-being" has been one of the most used, but least agreed upon, terms in mental health. Now, a landmark study led by Adelaide University and Be Well Co has brought alignment to one of mental health's ...
