A new study points to Sirt1 as a driver of neuroendocrine prostate cancer and suggests that blocking it could slow or prevent tumor growth.

New research suggests persistent atrial fibrillation is not mainly a disease of the left atrium, but one that profoundly alters both upper chambers of the heart.

Researchers say a new imaging workflow can map dozens of proteins in human brain tissue at once, uncovering an immune cell population that appears almost exclusively near a specific Alzheimer’s lesion.

Researchers at Ben-Gurion University say semaglutide and colchicine protect the heart through different mechanisms after injury, offering a clearer picture of how existing drugs might help prevent atrial fibrillation

New research highlighted by Medical Xpress suggests osteoporosis in postmenopausal women may be associated not only with fracture risk but also with a higher overall risk of death.

Researchers say existing MRI data may help doctors measure blood-brain barrier damage after an ischemic stroke, offering a new way to estimate recovery risk and tailor treatment.

A new report says brain imaging is revealing migraine headache subtypes, adding to evidence that the condition is more complex than a single category of severe headache.

A new report highlighted by Medical Xpress suggests a brain-based index may help reveal Alzheimer’s risk patterns in adults as young as 30, potentially shifting attention to much earlier stages of risk.

A new critique of global medical research argues that Africa carries a major disease burden while remaining underrepresented in clinical trials, raising questions about how universal today’s evidence base really is.

A new research clue suggests some patients with aplastic anemia may regain marrow function because protective blood stem cell clones help restore blood production.

A Medical Xpress report says small abnormalities in blood sugar, lipids, and inflammation years before pregnancy are linked to later risk of high blood pressure in pregnancy and preeclampsia.

Researchers at UC San Francisco used neuron-level probes in patients with epilepsy to show that subtle abnormal brain events may follow a detectable pattern up to a full second before they happen.

An Indiana University School of Medicine team says it has found a new way to read the brain’s energy network patterns, offering a potential window into how Alzheimer’s progresses across the disease spectrum.

A pilot study published in Nature Medicine suggests a blood-filtering approach for preeclampsia can be used safely in pregnancy, potentially pointing toward one of the first targeted treatments for a condition that still

A preclinical study from Marshall University suggests a dexmedetomidine-ketamine combination may control methamphetamine-induced agitation with deeper early sedation and fewer side effects than high-dose dexmedetomidine,

A study of more than 617,000 people adds mechanistic detail to the growing case that Epstein-Barr virus helps drive multiple sclerosis by altering immune-cell behavior and activating risk-related genes.

A new Science paper reports that HNF1B integrates signals in a feed-forward loop associated with kidney disease progression, highlighting a regulatory mechanism for further study.

A newly reported brain research tool is designed to help scientists see how different brain cell types work together using signals recorded by inserted probes.

Drexel University researchers report a critical metabolic vulnerability in breast cancer that has spread to the brain, pointing toward a possible therapeutic target for one of oncology’s hardest problems.

An international analysis led by the University of Sydney found that a hormone procedure commonly offered as an IVF add-on does not improve the chances of pregnancy.
