GLP-1 drugs may help curb addiction by targeting reward pathways

GLP-1 receptor agonists, already used for Type 2 diabetes and obesity, show promise in reducing alcohol and drug-seeking behaviors through central reward and dopamine-related pathways. Most evidence remains preclinical, with limited early human data, so larger clinical trials are needed before these drugs can be recommended for addiction treatment.

AI passed a classic Turing test by mastering the art of human small talk

In a standard three-party Turing test, persona-prompted LLMs were often judged to be human, with GPT-4.5 selected over real people 73% of the time in 5-minute trials. The findings suggest that short human-AI interactions now hinge less on factual intelligence and more on social style, conversational flow, and humanlike persona cues.

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.

Minimal exposure to modern medicine rapidly alters the human microbiome

Even minimal exposure to modern medicine can rapidly change the human microbiome. In a new study publishing May 20 in the Cell Press journal Cell Reports, researchers reveal that the gut microbes of remote Amazonian Indigenous communities began shifting toward patterns more commonly seen in urban, industrialized populations after only a few medical visits.

ChatCPR instructor delivers near-perfect CPR guidance in proof-of-concept study

A proof-of-concept JAMA Internal Medicine study found that widely available AI models could deliver many guideline-concordant CPR instructions in simulated out-of-hospital cardiac arrest scenarios. A purpose-built AI agent, ChatCPR, achieved higher checklist-based adherence than baseline AI models and dispatcher-assisted CPR instructions, but prospective real-world validation is still needed.

Cytokine-armored CAR-T cell therapy successfully attacks aggressive brain tumors in mice

Scientists at the UCLA Health Jonsson Comprehensive Cancer Center have developed a new cytokine-armored CAR-T cell therapy that helps the immune system better attack aggressive brain tumors in mice while reducing dangerous side effects that have long limited immune-based treatments for glioblastoma, one of the deadliest and most treatment-resistant brain cancers.

Scientists link schizophrenia risk gene to early cortical neuron changes

Researchers at King's College London have identified the biological nature and timing of changes in human cortical neurons caused by altering activity of a schizophrenia-associated gene in developing human neurons.

Restoring ADAR2 enzyme reduces metastatic spread in osteosarcoma

Osteosarcoma is the most common primary bone cancer in children, adolescents, and young adults. Although chemotherapy and surgery have improved survival for localized disease, outcomes remain poor when tumors spread to the lungs or return after treatment.

Real-time memory tests identify alcohol-induced blackouts as they happen

It's not surprising if someone experiences memory loss, or a 'blackout,' while drinking alcohol. While common, blackouts are considered a public health concern linked to injury, arrest, assault and overdose.

Fluid viscosity drives mechanical memory and invasion in glioblastoma

Most cancer studies focus on chemical signals or stiff tumor surroundings, but the stickiness of the fluid itself has received little attention.

Spatial modeling of tissue compartments predicts breast cancer treatment response

HER2-positive breast cancer accounts for about 20% of breast cancer cases and is generally associated with more aggressive behavior and a higher risk of distant metastasis, while pathologic complete response (pCR) after neoadjuvant chemotherapy is strongly linked to better survival outcomes.

Blood protein biomarkers predict psychosis risk in Asian youth

A new study by researchers from NHG Health's Institute of Mental Health (IMH) and Nanyang Technological University, Singapore's (NTU Singapore) Lee Kong Chian School of Medicine (LKCMedicine) has identified blood-based proteomic biomarkers that may help predict who among the at-risk group is at increased risk of developing psychosis.
