Scripps Research wins $4 million CIRM grant to develop novel platform for neurodevelopmental disorders

Most people are born with two functioning copies of each gene-one inherited from each parent. In many cases, having just one working copy is enough for the body to function normally.

Obesity’s health risks shift with age and sex, new genetic study reveals

Using a new time-resolved Mendelian randomization approach in over 360,000 UK Biobank participants, Karlsson et al. revealed that the causal impact of obesity changes across life, with distinct age- and sex-specific risk patterns for diabetes, heart disease, atrial fibrillation, and osteoarthritis.

Study finds up to 5% of Americans carry genetic mutations linked to increased cancer susceptibility

New Cleveland Clinic research reveals that up to 5% of Americans – approximately 17 million people – carry genetic mutations or "variants" linked to increased cancer susceptibility, regardless of risk factors like personal or family cancer history.

Unraveling the mystery of motor neuron degeneration in ALS

ALS, also known as Lou Gehrig's disease, is among the most challenging neurological disorders: relentlessly progressive, universally fatal, and without a cure even after more than a century and a half of research.

Prenatal air pollution exposure tied to higher autism risk in children

A population-based study of over two million births in Ontario found that prenatal exposure to the sulfate and ammonium components of fine particulate matter (PM₂.₅) was associated with a higher risk of autism spectrum disorder. The risk was greatest during mid to late pregnancy and among infants in urban, lower-income neighborhoods.

Study unravels the genetic shield against winter vomiting disease

Winter vomiting disease is caused by the Norovirus, which is most virulent during the colder half of the year.

Unlocking the secrets of vascular health through eye imaging

The tiny blood vessels in your eyes might hold the key to predicting a person's risk of developing heart disease and how fast they're biologically aging, according to researchers at McMaster University and Population Health Research Institute (PHRI) - a joint institute of Hamilton Health Sciences and McMaster.

Researchers trace the ancient origins of an urban mosquito species

New research has uncovered the ancient origins of an urban mosquito species, Culex pipiens form molestus, also known as the 'London Underground mosquito' – disproving a long-held theory of when it first evolved.

People with both cavities and gum disease may face higher ischemic stroke risk

People with both cavities and gum disease may face a higher risk of ischemic stroke, according to a study published on October 22, 2025, in Neurology Open Access, an official journal of the American Academy of Neurology.

Exposure to bright light at night can increase heart disease risk

A new study led by Flinders University has found that being exposed to bright light at night can significantly increase the chances of developing serious heart problems, including heart attacks, strokes and heart failure.

Psoriasis-linked gene mutation may also play a surprising role in gut health

A mutation previously linked to skin disorders like psoriasis may also play a surprising role in gut health, according to new research published by scientists at VIB-UGent and colleagues from UGent, the University of Barcelona, and University College London.

Physically fit individuals may better cope with dehydration stress

Individuals who are physically fit may be better equipped to handle the negative effects of dehydration, according to research from the University of California, Riverside. In a study using selectively bred "high-runner" mice, the scientists found that fitter animals increased their voluntary running activity when deprived of water - a finding that could have implications for human performance and health under environmental stress.

New gene-editing method can correct many disease-causing mutations in mammalian cells

Some genetic disorders-such as cystic fibrosis, hemophilia and Tay Sachs disease-involve many mutations in a person's genome, often with enough variation that even two individuals who share the same disorder might have a different combination of mutations.
