T cell senescence shapes cancer prognosis and immunotherapy response

Thu, 07/31/2025 - 08:54
T cell senescence occurs in the TME, affecting cancer prognosis and immunotherapy efficacy. The TME induces T cell senescence through multiple pathways, including persistent stimulation by tumor-associated antigens, metabolic pathway alterations, activation of chronic inflammatory responses, proliferation of immunosuppressive cells, and T cell damage caused by tumor radiotherapy and chemotherapy.

Cancer-associated fibroblasts exhibit paradoxical effects on immunotherapy

Thu, 07/31/2025 - 08:48
Cancer-associated fibroblasts (CAFs) – critical but enigmatic players in tumors – exhibit "paradoxical" effects on immunotherapy, according to a new review in Clinical and Translational Discovery.

Scarred liver tissue creates fertile ground for cancer development

Thu, 07/31/2025 - 07:48
Over 80% of hepatocellular carcinoma (HCC) – the third-leading cause of cancer deaths globally – emerges from advanced liver fibrosis or cirrhosis. A comprehensive review in Hepatology International synthesizes decades of research to reveal how scarred liver tissue becomes a breeding ground for cancer.

Metformin lowers blood sugar by acting on brain pathways

Thu, 07/31/2025 - 07:23
Although metformin has been the go-to medication to manage type 2 diabetes for more than 60 years, researchers still do not have a complete picture of how it works.

Black Death victims offer clues to childhood malnutrition and adult disease

Thu, 07/31/2025 - 07:16
The Black Death arrived on the shores of England in May 1348 and, in less than two years, spread throughout the country, killing an estimated 2 million people.

Promising treatment slows liver cancer by inhibiting fat enzyme

Thu, 07/31/2025 - 07:10
Liver cancer cells thrive on fat, posing a serious risk of cancer diagnosis for millions of people living with fatty liver disease.

Perceived sickness activates real immune responses

Thu, 07/31/2025 - 05:26
Findings indicate the brain's anticipatory response to virtual infections activates immune mechanisms, showcasing the link between neuroscience and immunity.

Promega Plasmid Collection, available through Addgene, equips industry and academic researchers with powerful bioluminescent assays that provide deeper insights into endogenous cellular biology

Thu, 07/31/2025 - 00:06
Addgene, a purpose-driven organization helping scientists conduct experiments with greater ease, speed, and reproducibility, today announced a strategic partnership with Promega to expand Addgene’s vast plasmid repository with the launch of the Promega Plasmid Collection.

Can stacking creatine and β-alanine give you extra gains? Here’s what science says

Wed, 07/30/2025 - 22:45
Co-supplementation with creatine and β-alanine may enhance high-intensity exercise performance, especially in repeated short bursts. However, it offers no additional benefit over creatine alone for maximal strength, aerobic capacity, or body composition.

Why Spirulina could be a helpful natural option for lowering blood pressure

Wed, 07/30/2025 - 21:43
A comprehensive meta-analysis found that consuming whole microalgae, especially Spirulina, can significantly lower blood pressure, particularly in adults with elevated levels. No significant effects were observed for macroalgae or algae extracts.

Brisk walking for just 15 minutes a day cuts death risk in low-income adults, study shows

Wed, 07/30/2025 - 20:50
Fast walking for as little as 15 minutes per day was linked to a nearly 20% reduction in mortality among predominantly Black and low-income American adults. Slow walking showed minimal benefit, but prolonged slow walking reduced the risk of death from ischemic heart disease.

E-scooter riders are three times more likely than cyclists to end up in hospital, study shows

Wed, 07/30/2025 - 20:19
Stand-up electric scooter riders in Helsinki are over three times more likely than cyclists to sustain injuries requiring emergency care, with head trauma and alcohol use significantly more common in scooter crashes. Helmet use among scooter riders remains exceptionally low.

Physicians lead effort to end race-based bias in lung function testing

Wed, 07/30/2025 - 20:08
Last July, a team of physicians and researchers successfully proposed modifications to the American Medical Association (AMA) Guides to the Evaluation of Permanent Impairment, advocating against the use of race in lung function testing.

Immunocompromised people susceptible to skin cancer caused directly by beta-HPV

Wed, 07/30/2025 - 20:04
Researchers at the National Institutes of Health (NIH) have shown for the first time that a type of human papillomavirus (HPV) commonly found on the skin can directly cause a form of skin cancer called cutaneous squamous cell carcinoma (cSCC) when certain immune cells malfunction.

Several healthy eating patterns may reduce the risk of type 2 diabetes across diverse ethnic groups

Wed, 07/30/2025 - 19:50
A large new meta-analysis of more than 800,000 participants to be presented at this year's Annual Meeting of the European Association for the Study of Diabetes (EASD) in Vienna, Austria (15-19 September) shows that high adherence to three well-established healthy eating patterns is linked to a lower risk of type 2 diabetes, regardless of one's ethnicity.

Infant brain activity shows faster maturation after general anesthesia

Wed, 07/30/2025 - 15:44
New research published today in Proceedings of the National Academy of Sciences (PNAS) finds that prolonged and/or repeated exposure to gamma-aminobutyric acid (GABA) anesthetic agents (sevoflurane, propofol) for infants in the first two months of life resulted in an accelerated maturation of brain electrical activity patterns evoked by visual stimuli when recorded at 2-5 months of age, compared to infants who did not have early general anesthesia exposure.

Low FODMAP diet found to repair leaky gut in IBS-D patients

Wed, 07/30/2025 - 15:32
In a study, patients with irritable bowel syndrome with diarrhea, or IBS-D, who went on a low FODMAP diet saw an improvement of colonic barrier dysfunction, commonly known as "leaky gut."

Thalamic feedback pathway found to tune sensory perception

Wed, 07/30/2025 - 15:24
The cerebral cortex processes sensory information via a complex network of neural connections. How are these signals modulated to refine perception? A team from the University of Geneva (UNIGE) has identified a mechanism by which certain thalamic projections target neurons and modify their excitability.

Respiratory infections can reactivate dormant breast cancer cells

Wed, 07/30/2025 - 15:20
Researchers at the University of Colorado Anschutz Medical Campus, Montefiore Einstein Comprehensive Cancer Center (MECCC), and Utrecht University have found the first direct evidence that common respiratory infections, including COVID-19 and influenza, can awaken dormant breast cancer cells that have spread to the lungs, setting the stage for new metastatic tumors.

Flavor bans linked to drop in e-cigarette use but may slow decline in smoking

Wed, 07/30/2025 - 15:16
A new study by investigators from Mass General Brigham examined the effects of policies banning flavored e-cigarettes on adults and young people.
