Research identifies a neurodevelopmental spectrum for ADHD and autism, emphasizing genetic links and their impact on cognitive and educational outcomes.

Using CHARLS data from 2011 to 2020, researchers found that sleep duration and self-reported sleep quality were associated with Parkinson’s disease risk in middle-aged and older Chinese adults. Short sleep was linked to higher PD risk, while age-specific patterns suggested a linear association in adults aged ≤60 years and a U-shaped relationship in those aged >60 years.

A trial led by University of Pittsburgh researchers and published today in The Lancet Diabetes & Endocrinology adds nuance to the question of whether older human insulins are as effective as insulin analogues in low-resource settings.

More than 1.15 million assisted reproductive technology (ART) treatment cycles were reported across Europe in 2023, according to preliminary data presented by the European IVF Monitoring (EIM) Consortium at the 42nd Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE).

A new nationwide study has found substantial regional differences in sperm quality, with men in the highest-performing region recording almost double the total motile sperm count of those in the lowest-performing region.

Consumption of ultra-processed food (UPF) results in a distinct metabolic 'signature' in the blood, associated with potentially adverse health conditions, a new study by an international team of researchers finds.

People with endometriosis have a distinct pattern of hormones which could be identified by a blood test, with the potential to revolutionise diagnosis of the condition, research suggests.

A landmark international study has found that halving patient out-of-pocket costs was associated with a 2.67-fold increase in births achieved through assisted reproductive technology (ART).

New research presented today at the 42nd Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) suggests that exposure to air pollution may impact genes associated with sperm development, raising new questions about male fertility, pregnancy outcomes and offspring health.

Antibiotics save lives, but they are also a global health threat. Scientist Noëlie Maurin at SINTEF has an idea that could help solve the problem: Remove antibiotic residues before they are flushed down the drain.

Researchers studying the impact of cocaine in mice have found that just one exposure to the drug can create changes in brain cells that persist for at least two weeks.

Announcing a new article publication in BIO Integration. The authors of this article developed CellDeathAnalysis (v0.4.0), an R package providing a unified framework for analyzing 14 cell death pathways in bulk RNA-seq data.

Birth control pills are safe and effective for millions of women, but researchers are still working to understand how the hormones they contain may influence eating behavior.

People who shortened their sleep by around 80 minutes a night for six weeks gained weight-one pound on average-and were more sedentary, researchers at Columbia University Vagelos College of Physicians and Surgeons have found.

Two people may be the same age and have similar family histories or risk factors, yet only one of them may develop thrombosis.

In people with severely compromised immune systems, the JC polyomavirus can trigger a currently untreatable, usually fatal brain disease.

A new HIV vaccine developed by La Jolla Institute for Immunology (LJI), Scripps Research scientists, and IAVI has the potential to protect humans from developing HIV infection and AIDS.

Parkinson's disease (PD) is the second most common form of neurodegenerative disease and afflicts more than ten million people worldwide. While current therapies address disease symptoms, they do not prevent the underlying neurodegeneration that drives the disease.

In health care, it is often the smallest moments that carry the greatest meaning - a quiet conversation with a patient, a shared reflection with colleagues, or a hand held in silence.

The researchers treated 5‑month‑old 5xFAD mice – a model with aggressive amyloid deposition – with 810‑nm light (25 mW/cm² at the scalp, ~6.25 mW/cm² brain dose for CW, and half that for 40‑Hz due to 50% duty cycle) for 10 minutes daily over 37 days.
