Sex-specific changes in gluteus maximus shape linked to aging and metabolic health

The shape of the gluteus maximus muscle in the buttocks changes in different ways with aging, lifestyle, frailty, osteoporosis and type 2 diabetes, and these changes differ between women and men, according to new research being presented next week at the annual meeting of the Radiological Society of North America (RSNA).

Genetic factors behind impulsive choices tied to metabolic and mental health

Researchers from University of California San Diego have identified 11 genetic regions linked to delay discounting - the tendency to prefer smaller, immediate rewards over larger, delayed ones - shedding new light on how impulsive decision-making relates to both mental and physical health.

Study reveals metabolic benefits of reducing ultra-processed foods in older adults

A controlled feeding study out of South Dakota State University shows that older adults who ate fewer ultra-processed foods naturally consumed fewer calories, lost weight and abdominal fat, and showed improvements in insulin, nutrient-sensing hormones, and inflammation.

New research questions reliability of macaque models for TIGIT-targeted cancer treatments

A new study published in the Journal of Biological Chemistry from UC Davis Comprehensive Cancer Center finds that TIGIT, an immune checkpoint receptor targeted by cancer immunotherapy drugs, triggers a different response in rhesus macaques compared to humans.

Study uncovers how a specific immune cell may contribute to HIV persistence

Researchers from the Institute of Human Virology (IHV) at the University of Maryland School of Medicine have discovered how a specific type of immune cell may contribute to the persistence of HIV infections.

Calcium-activated switch improves delivery and potency of cancer-fighting drugs

Cancer-fighting antibody drugs are designed to penetrate tumor cells and release a lethal payload deep within, but too often they don't make it that far.

Discovery reveals role of EGFR in resistance to KRAS inhibitors in pancreatic cancer

A study led by University of Cincinnati Cancer Center researchers sheds new light on how pancreatic cancer cells resist treatment and points to potential new combination therapies to make treatments more effective.

Study introduces cost-effective approach to analyze entire T-cell repertoire

Studying T cells, the immune cells most responsible for responding to infections and cancers, just received a significant boost in the form of a new technique from St. Jude Children's Research Hospital.

Scientists reverse aging in blood stem cells by restoring lysosome function

Researchers at the Icahn School of Medicine at Mount Sinai have discovered how to reverse aging in blood-forming stem cells in mice by correcting defects in the stem cell's lysosomes.

Study reveals biological insights into triple negative breast cancer

Researchers at the LSU LCMC Health Cancer Center have published groundbreaking findings in NPJ Breast Cancer that sheds new light on triple-negative breast cancer (TNBC), one of the most aggressive forms of breast cancer.

New project aims to predict bone healing and reduce complications from fractures

Every year, nearly 10 million Americans experience a broken bone. A quarter of patients with lower leg fractures face delayed healing, and one in 10 patients will develop a nonunion, a break that requires additional major surgery to heal.

Ultra-processed foods make up one-fifth of Italian calories - here’s who's most affected

Italian researchers found that ultra-processed foods make up about 20 percent of daily calories in adults, with younger, single, and Northern residents consuming the most. Higher adherence to the Mediterranean Diet was strongly linked to lower UPF intake across all sociodemographic groups.

Arginine slows amyloid buildup and improves brain outcomes in Alzheimer’s disease models

Arginine reduced amyloid beta aggregation in vitro and in both Drosophila and AppNL-G-F mouse models of Alzheimer’s disease, leading to fewer dense-core plaques and improved behavior. The study provides preclinical evidence that oral arginine may modulate amyloid pathology, although high dosing requirements and model limitations constrain human translation.

Can diet calm early memory problems? Anti-inflammatory Mediterranean eating shows promise

Older women who follow a strongly anti-inflammatory Mediterranean diet report far fewer subjective memory complaints than those who do not. The AnMED pattern outperforms both traditional Mediterranean and MIND diets, showing a clear advantage for protecting early cognitive symptoms.

Black cumin: A promising natural agent with potential against chronic diseases

Black cumin seeds contain diverse secondary metabolites, including thymoquinone, flavonoids, triterpenoids and alkaloids, that demonstrate broad antimicrobial, antioxidant, anti-inflammatory and anticancer activity. Early preclinical and limited clinical evidence shows therapeutic potential across chronic diseases, supported by mechanistic and structure activity relationship findings.

Gut neurons control immunity attack or repair

Beneath the surface of your gut lies a vast network of neurons—as many as in your spinal cord. New research from the Champalimaud Foundation (CF) in Lisbon shows that in mice this "second brain" helps decide whether the immune system should go into attack mode or start repairing tissue.

Vegan diet with unhealthy plant foods promotes greater weight loss than Mediterranean diet

Eating a vegan diet increases consumption of plant-based foods-including those defined as "unhealthy" by the plant-based diet index-leading to greater weight loss than the Mediterranean diet, finds a new analysis by the Physicians Committee for Responsible Medicine published in Frontiers in Nutrition.

Identifying vulnerabilities and new targets for hard-to-treat carcinomas

Some tumors are almost impossible to treat. That's especially true for carcinomas, which don't behave like other malignancies.

New discovery could reshape how scientists think about Alzheimer’s treatment

Rutgers neuroscientist Peng Jiang was visiting his hometown of Qianshan, a city in China's Anhui province, when a neighbor came to his parents' house with a story that would stay with him.

Researchers use organoids to study the earliest moments of electrical activity in the brain

Humans have long wondered when and how we begin to form thoughts. Are we born with a pre-configured brain, or do thought patterns only begin to emerge in response to our sensory experiences of the world around us? Now, science is getting closer to answering the questions philosophers have pondered for centuries.
