Harder for a child with an NDD if the mother had a difficult childhood

A study by University of Gothenburg found that mothers' adverse childhood experiences increase risk of children developing ADHD and autism. In contrast, fathers' childhood experiences show no association with their children's neurodevelopmental disorders. The researchers call for a broader approach to parental support.

Locating microplastic hotspots along the Texas coast

A new study reveals that microplastics accumulate and disperse in marine environments along the Texas coast, particularly in estuaries and bays. The researchers found that winds and shrimp fishing can transport microplastics out of these areas and into the Gulf of Mexico.

Rain barrel basics: Conserving water but not mosquito habitats

Researchers found over half of residential rain barrels in Champaign County had at least one mosquito-positive barrel. Effective prevention methods include mesh coverings, approved insecticides like Bacillus thuringiensis israelensis, and treating the water with chlorine or predators of mosquito larvae.

New study analyzes how Reddit communities are adapting to AI

Reddit communities are adapting their policies to address AI-generated content, with subreddits featuring AI rules more than doubling in 16 months. AI rules are most common in art and celebrity-focused communities, which address concerns about image, audio, and video quality.

New study reveals how tumors hijack key nutrient to evade immune attack

A new study reveals that breast cancer cells exploit the amino acid arginine to drive aggressive tumor behavior and resistance to immunotherapies. Cancer cells act as 'arginine factories,' saturating the tumor microenvironment with this nutrient, which is then used by immune cells to suppress cancer-fighting CD8+ T cells.

New system for the early detection of autism

A new system for early detection of Autism Spectrum Disorder (ASD) has been developed using virtual reality and artificial intelligence. The system, which uses biomarkers related to behavior, motor activity, and gaze direction, achieves an accuracy of over 85%, surpassing traditional methods.

What if we find nothing in our search for life beyond Earth?

A recent study by ETH Zurich researchers suggests that if scientists examine 40–80 planets and find no signs of life, they can confidently conclude that fewer than 10–20% of similar planets harbor life. This finding would enable scientists to put a meaningful upper limit on the prevalence of life in the universe.

Stephen Hauser wins breakthrough prize for role in redefining MS

Neuro-immunologist Stephen Hauser has won the 2025 Breakthrough Prize in Life Sciences for his role in identifying the immune system's primary driver of damage to nerve cells in multiple sclerosis. His B-cell theory has led to the development of therapies that have transformed treatment, reducing relapses and improving prognosis.

Transparency in government is good for global health

A field experiment in Chinese cities shows that increased transparency leads to a 37% reduction in high-polluting company violations and a 90% increase in regulatory inspections. Air pollution drops by 8-10%, with no evidence of direct public pressure as a factor.

Cardioprotective glucose-lowering agents and dementia risk

A meta-analysis of randomized clinical trials found that glucagon-like peptide-1 receptor agonists (GLP-1RAs) were associated with a statistically significant reduction in all-cause dementia. Cardioprotective glucose-lowering therapies, however, did not show an overall reduction in dementia risk.

Spinning into resistance: the flagella’s hidden role

Researchers found that bacterial movement and flagellar rotation activate conjugation genes, enabling DNA transfer in liquid environments. This discovery provides insight into the spread of antibiotic resistance across species.
