Basilar trunk artery aneurysms (BTAs) are among the rarest and most complex types of brain aneurysms, occurring in a critical vessel that supplies blood to the brainstem. Because of their location and low incidence, there has been limited research guiding how best to treat them, leaving neurosurgeons with few large datasets to inform clinical decisions.

Although cancer immunotherapy has transformed treatment by harnessing the immune system to eliminate tumors, only a small subset of patients benefit. Many solid tumors remain "cold," characterized by poor immune cell infiltration and resistance to immune checkpoint blockade (ICB).

Researchers have introduced a novel diagnostics method that can more sensitively detect gene fusions in B-cell acute lymphoblastic leukemia (B-ALL), the most common type of pediatric cancer, compared to other publicly available fusion detection algorithms.

Researchers from A*STAR Genome Institute of Singapore (A*STAR GIS) have developed a new method, called 'sm-PORE-cupine', to study individual RNA molecules and reveal how their structures influence gene regulation, a fundamental process that affects how cells function in health and disease.

A healthy brain may help protect thinking and memory skills from the early effects of Alzheimer's disease, a new study has found.

Blood tests to detect potential signs of prostate cancer likely reduce the risk of dying from prostate cancer, an updated Cochrane review finds. This is a shift from the previous version of the review, which did not find sufficient evidence that screening reduced prostate cancer deaths.

Dietary supplements are widely used by people with Parkinson’s disease, but this review finds that none have yet been proven to slow disease progression. Biotics, nicotinamide riboside, and omega-3 fatty acids combined with vitamin E show the most promise, but larger, longer, and better-designed trials are needed.

The Nature study introduces “Sleep Chart,” a framework linking self-reported sleep duration with 23 biological aging clocks derived from MRI, plasma proteomics, and metabolomics. Across UK Biobank participants, the lowest biological age gaps generally appeared between 6.4 and 7.8 hours of sleep, while shorter and longer sleep were associated with higher disease and mortality risk.

A 2020 NEJM study of the 2018 to 2019 Epuyén outbreak showed that Andes virus spread from one zoonotic introduction into four generations of human infection, causing 34 cases and 11 deaths. The findings are newly relevant after WHO reported an ANDV cluster linked to the MV Hondius cruise ship, where close indoor exposure may have enabled onboard human-to-human transmission.

Perioperative medicine is emerging as a transformative, comprehensive, system-wide approach to patient care before, during, and after surgery – that reduces complication rates and hospital days, provides better health outcomes, and improves health system performance, according to a special article in the Online First edition of Anesthesiology, the peer-reviewed medical journal of the American Society of Anesthesiologists (ASA).

A study led by a University of Louisville School of Medicine pediatrics and child neurology researcher reveals how a specific signaling mechanism in microglia, the brain's immune cell, can regulate anxiety and grooming behaviors. These behaviors are core symptoms of autism and obsessive-compulsive spectrum disorders.

Increasing bone density in patients with a rare genetic condition that causes bones to break easily does not prevent fractures, a large clinical trial has found.

Researchers at the Stanford School of Medicine have found that ethnicity and geography may influence human molecular makeup - from metabolism and immunity to gut microbiota and biological aging.

Materials scientists have designed brain-stimulating contact lenses that are as effective as Prozac at treating depression in mice. The soft, transparent contact lenses have in-built electrodes that deliver mild electrical signals to the brain via the retina to stimulate specific brain regions associated with depression.

A child's future heart health may be partially shaped before they are born, reports a new Northwestern Medicine study that found pregnancy complications are linked to poorer cardiovascular health in offspring more than 20 years later.

Thousands of Americans develop chronic persistent symptoms-such as fatigue, cognitive difficulties ("brain fog"), and other debilitating issues-each year following acute infections from Lyme disease, COVID-19, and other pathogens. Efforts to identify causes and produce treatments have failed. However, 16 leading researchers think they know part of the problem: study design.

Early and accurate prognostic assessment is crucial to prevent disease progression in liver failure. Thyroid hormones (THs), particularly triiodothyronine (T3), are key metabolic regulators and play an important role in liver regeneration. Liver failure is frequently complicated by non‑thyroidal illness syndrome (NTIS), characterized by low T3 with normal or slightly elevated TSH and T4.

A new meta-analysis in the May 2026 issue of JNCCN-Journal of the National Comprehensive Cancer Network provides updated evidence that methylphenidate-type psychostimulants-a class of medication that increases dopamine and norepinephrine availability in the brain-can provide meaningful relief for cancer-related fatigue.

Even in the primary visual cortex, a brain region named for its specialized role in processing basic features of what the eyes see, not every neuron ends up answering the call to process properties of visual input. Maybe that's because each neuron receives a wide variety of inputs via thousands of circuit connections, or "synapses," and has to opt to respond to the visual information vs. something else.

A research project led by the Institute for Research in Nutrition and Food Safety (INSA) and the Faculty of Pharmacy and Food Sciences at the University of Barcelona, together with the Molecular Biology Institute of Barcelona (IBMB) of the CSIC (which stands for Consejo Superior de Investigaciones Científicas), has successfully designed and tested a gluten-degrading molecule that is a promising ally in the management of coeliac disease, an autoimmune disease whose symptoms are triggered by the consumption of gluten and other prolamins found in cereals.
