How an AI system learned to write expert-level scientific code

ERA is an AI system that uses large language models and tree search to automatically write, test, and refine scientific software for measurable research tasks. Across bioinformatics, COVID-19 forecasting, time-series analysis, geospatial modeling, neuroscience, and numerical computation, ERA produced expert-level solutions that often surpassed established human-developed methods.

Most college students with psychosis lack recommended combination treatment

Although the majority of students sought and received therapy or counseling in the past 12 months, less than 40 percent received the recommended combination of therapy/counseling and antipsychotic medication, suggesting potential barriers to accessing this medication.

Anti-inflammatory drug tocilizumab shows promise for difficult-to-treat depression

Immunotherapy could be a promising new treatment option for patients with difficult-to-treat depression. This is a key finding from a University of Bristol-led pilot randomised controlled clinical trial, published in JAMA Psychiatry today [20 May].

Diverse AI foundation models transform universal eye care imaging

Artificial intelligence (AI) has already changed many aspects of medical imaging, but traditional ophthalmic AI systems are often built for a single disease, dataset, or task.

Why AI tools need clearer guardrails in high-stakes health research

AI-enabled research tools can accelerate health research, but their data-science roots may clash with epidemiological workflows built around prespecified designs, causal reasoning, bias control, and reproducibility. The article argues that researchers should integrate AI cautiously, using clear workflow boundaries, peer review of AI outputs, and sustained human accountability.

New guidelines urge earlier cholesterol treatment to prevent heart disease

Doctors should consider treating high cholesterol much earlier and more aggressively than they have in the past, according to a new perspective by Weill Cornell Medicine, NewYork-Presbyterian and Yale School of Medicine investigators.

Study supports flexible blood transfusion options in emergency trauma care

Giving whole blood or the component parts of blood are equally effective options for paramedics and emergency medical technicians to use in treating patients with severe, traumatic bleeding before arriving at the hospital, according to a large, nationwide trial directed by University of Pittsburgh and UPMC clinicians and scientists.

Early protein and calorie supplements lead to fewer high-risk newborns

In parts of the world where daily nutrition is unstable, pregnancy and newborn health are more precarious. A new study led by epidemiologist Dongqing Wang of the George Mason University College of Public Health adds to the evidence that improving maternal nutrition during pregnancy may be a key intervention to improve birth outcomes.

Popular analysis technique hides patient variability in Alzheimer's drug trials

A statistical approach being used to support a new class of Alzheimer's drugs may lead to overstated claims about how the drugs work, according to a new study led by researchers at the Brown University School of Public Health.

Body weight and genes directly alter gut microbiota composition

Your body weight and genes influence the types of bacteria you have in your gut. In turn, this appears to affect the risk of developing conditions such as coeliac disease and haemorrhoids.

Scientists call for innovative strategies to combat tuberculosis superspreaders

Superspreading became a familiar concept to many during the COVID-19 pandemic. Prior studies examining infectious disease epidemics, including those on COVID-19, have found that some individuals are much more likely to transmit infections to other people. Superspreading, when one person with an infection passes it to an unusually large number of other people, is a key feature of tuberculosis (TB) epidemiology.

Asymptomatic transmission plays a prominent role in mpox infection patterns

A Kaiser Permanente study of nearly 8,000 men shows that in mid- to late 2024, mpox was far more common among men who have sex with men than previously thought. Individuals without symptoms accounted for most infections and likely played a prominent role in transmission, contrary to prior assumptions that people had to be symptomatic to spread the disease.

How Andes virus super-spreaders reveal the risk behind the MV Hondius hantavirus cluster

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.
