Healthy thymus gland linked to longer life and immune stability

The thymus is a small organ located in the upper chest that plays a central role in the immune system: it produces T cells - specialized immune cells that recognize and fight pathogens.

The new microchip electrophoresis system MultiNA II MCE-301- High sensitivity detection, improved analysis function and operability

Shimadzu has recently released the MultiNA II MCE-301 microchip electrophoresis system. By automating the entire process of electrophoresis, which takes more than two hours by hand (creation of gels, dispensing reagents, dispensing sample, separation, dyeing, cleaning of equipment), the company significantly improves the efficiency of genetic analysis operations.

Proposed policy solutions for the worldwide rise in chronic diseases

Chronic diseases including cancer, diabetes, neurocognitive disorders and infertility are rising globally, with health-harming products such as fossil fuels, tobacco, ultra‑processed foods, toxic chemicals, plastics and alcohol being major contributors, say the authors of a new paper published in New England Journal of Medicine (NEJM). The authors include proposed solutions, including policy safeguards and a stronger research focus on the risks to health connected with corporate activity.

Scientists discover how brain development programs fuel pediatric tumors

A team of researchers at Baylor College of Medicine, St. Jude Children's Research Hospital, Texas Children's Hospital, and collaborating institutions reveals in the journal Nature a novel mechanism that drives the development of pediatric supratentorial ependymoma (EPN), the third most common pediatric brain tumor. The findings suggest potential new approaches to treat these aggressive and chemo-resistant tumors.

The molecular mechanism that turns cool temps into nerve signals

When you reach into a bucket of ice, open your front door on a snowy day, or feel the tingle of menthol toothpaste, a protein in your nerve cells called TRPM8 springs into action, opening like a tiny gate to send a "cold" signal to your brain.

Study links androgens to aggressive childhood brain tumor growth

An international team led by researchers at Baylor College of Medicine, Texas Children's Hospital, McGill University and University of Pittsburgh School of Medicine has discovered what drives the growth of a lethal pediatric brain tumor called Posterior Fossa Type A (PFA) ependymoma.

New brain atlas reveals how the human neocortex forms over time

In a bid to better understand, and potentially treat, a host of conditions that affect early cognition, neurodevelopment and the brain later in life, investigators at Johns Hopkins Medicine and colleagues throughout the world have been mapping the molecular construction of the human brain.

New tool aims to support the delivery of whole-person care in everyday clinical practice

As whole-person care accelerates across the U.S. health care system, clinicians face a persistent and consequential gap: the lifestyle and upstream health factors that drive chronic disease remain largely unmeasured, undocumented, and uncompensated in health care data systems.

New guidance aims to standardize tumor mutational burden in cancer

Immune checkpoint inhibitors have transformed cancer care, yet only a minority of patients respond to monotherapy, and immune-related adverse events remain a major concern.

Estradiol patches as effective as injections for locally advanced prostate cancer

Hormone patches are as good at controlling locally advanced prostate cancer as the injections typically used to deliver hormone therapy, according to the results of a large clinical trial led by UCL (University College London) researchers.

Immunotherapy plus chemotherapy improves outcomes in stage III dMMR colon cancer

A new study from researchers at the Alliance for Clinical Trials in Oncology (Alliance) shows that patients with stage III colon cancer with deficient deoxyribonucleic acid (DNA) mismatch repair (dMMR) had significantly better outcomes when the immunotherapy drug atezolizumab (Tecentriq®) was added to standard chemotherapy after surgery.

Stroke may trigger younger brain patterns in unaffected regions

In a new study published in The Lancet Digital Health, scientists at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) have discovered that the brains of people who experience severe physical impairment after a stroke may reorganize themselves in unexpected ways, showing signs of "younger" brain structure in undamaged regions as they adapt to injury.

Breast cancer cells exploit the lung's repair system to support tumor growth

Researchers at the CU Anschutz Cancer Center have discovered how breast cancer cells that spread to the lungs may take advantage of the body's natural healing response and how a commonly used drug might slow that process.

Study finds AI-generated X-rays can fool radiologists and chatbots

Researchers found that both radiologists and multimodal AI models had only moderate success distinguishing synthetic radiographs from real clinical images, even when told fakes were present. The study warns that increasingly realistic AI-generated X-rays could be misused in medicine, research, insurance, and litigation, strengthening the case for watermarking, clinician training, and dedicated detection tools.
