Scientists link poor sleep to decreased chemotherapy response via the gut

Sleep deprivation has long been known to weaken the immune system. Now UF Health Cancer Institute researchers have made a startling discovery: The gut microbiota drives changes to the immune system caused by chronic sleep loss. These changes promote cancer progression, disrupt circadian rhythm and weaken the effectiveness of chemotherapy.

Study explains the link between NDMA-contaminated water and childhood cancer

A new study from MIT suggests that a carcinogen that has been found in medications and in drinking water contaminated by chemical plants may have a much more severe impact on children than adults.

Psychedelic use is associated with major life changes across 10 domains

Researchers created a new questionnaire to measure major life changes linked to psychedelic use and found that most surveyed adults reporting naturalistic psychedelic use said psychedelics had influenced at least one major change in their lives. These changes most often involved goals, values, and spirituality, were usually rated positively, and were more commonly reported by people with more frequent use.

Why AI is becoming a powerful tool in cancer drug discovery

This Perspective reviews how AI is moving drug discovery from long, costly experimental pipelines toward earlier clinical translation, with an AI-designed TNIK inhibitor trial serving as an important proof-of-feasibility reference point. It argues that precision oncology could benefit from AI-driven integration of multi-omics, federated learning, and adaptive trial design, but only if validation, fairness, interpretability, and regulatory alignment improve.

Study finds popular AI chatbots often give problematic health advice

Researchers audited five popular public-facing AI chatbots across 250 health prompts and found that 49.6% of responses were problematic, with especially weak performance on open-ended questions and in nutrition and athletic performance. The study also found poor citation quality, difficult readability, and very few refusals to answer, raising concerns about the reliability of chatbots for everyday health information.

How the immune system may influence Alzheimer’s, Parkinson’s, and related diseases

This review argues that neurodegeneration is shaped not only by toxic protein buildup but also by immune signaling, with microglia and T cells able to either protect the brain or worsen damage depending on context. It also highlights aging, head injury, and viral infection as major forces that reshape CNS immunity and may influence disease progression and future treatment strategies.

Clinical barriers prevent hormone therapy access after cervical cancer treatment

Most oncologists say they would prescribe hormone therapy to cervical cancer patients who experience early menopause from radiation treatment, but barriers are keeping many from doing so in practice, according to a new University of Kentucky Markey Cancer Center study published in JAMA Network Open.

Scientists discover a biological "memory" of breastfeeding in child blood samples

Babies who are exclusively breastfed for at least three months carry markers in their blood that differ from babies who are not breastfed.

Researchers prove magnetic seizures are comparable to ECT in clinical response

A landmark international clinical trial led by researchers at the Centre for Addiction and Mental Health (CAMH) and University of California San Diego School of Medicine, published in The Lancet Psychiatry, has found that magnetic seizure therapy (MST) is as effective as electroconvulsive therapy (ECT)-the current gold-standard treatment for severe, treatment-resistant depression-with significantly fewer cognitive side effects. The study is the first large-scale, randomized clinical trial to directly compare MST with ECT, marking an important step toward a new treatment option for patients.

Study reveals why endometriosis pain persists after lesions are removed

Repeated menstrual cycles may do more than trigger endometriosis. They may rewire the brain.

Researchers discover a molecular signature to flag dysfunctional aging cells

UCLA researchers have identified a rogue population of immune cells that quietly accumulates in aging tissues and in the livers of people with fatty liver disease. Clearing these cells, they found, dramatically reduced inflammation and reversed liver damage in mice - even while the animals remained on an unhealthy diet.

Understanding cell messaging provides a blueprint for targeting inaccessible tumors

Researchers at University College Dublin have discovered a previously unknown "courier system" that cells use to deliver coherent biological messages between each other, opening new possibilities for medicine and biotechnology.

Scientists find "hidden" pre-cancer signs in advanced esophageal cancer patients

Scientists have found the strongest evidence to date that a condition known as Barrett's esophagus is the starting point for all cases of esophageal adenocarcinoma – the most common type of esophageal cancer in the developed world – even when telltale signs of this pre-cancerous stage are no longer visible.

New research reveals how bacteria "selflessly" share DNA through GTAs

Research has shed important new light on the enemies-turned-allies that allow bacteria to exchange genes, including those linked to antimicrobial resistance (AMR).

Superficial skin exposures pose a higher rabies risk than previously thought

While it was previously thought that keratinocytes (skin cells) were only passive conductors that allow the rabies virus to pass through, novel research reveals that these cells play a much more active role. The findings of a new study in the Journal of Investigative Dermatology (JID), published by Elsevier, provide direct evidence that keratinocytes can support viral replication and transmit the rabies virus to neurons. The investigators offer a mechanistic explanation for how superficial skin exposures from scratches or minor bites by dogs and bats can lead to neuroinvasion, contributing to the risk of infection.

Clearing amyloid beta shows no significant impact on dementia severity

Drugs that target amyloid beta proteins in the brain likely have no clinically meaningful positive effects, while increasing the risk of bleeding and swelling in the brain, a new Cochrane review has found.

Sunlight exposure via windows risks infant dehydration and skin damage

Researchers from the Universitat Politècnica de València, the Francesc de Borja University Hospital in Gandia and the La Ribera University Hospital, through the Fisabio Foundation, have found that sunlight passing through windows in homes is neither a safe nor a recommended alternative for preventing or treating neonatal jaundice, a condition affecting more than half of all newborns.

Epigenetic changes allow cancer cells to shift identity and survive drugs

Cancer drugs are designed to shut tumors down. But sometimes, in the very act of attacking a tumor, treatment can also help a small fraction of cancer cells become harder to kill. A new study from researchers at the Institute for Systems Biology (ISB) shows that cancer cells may begin escaping therapy much earlier - as the therapy itself triggers a stress response that drives some cancer cells into a temporary drug-tolerant state.
