New enzyme discovery reveals how breast milk feeds infant gut bacteria

Microbiologists have found that an enzyme, not normally associated with microbial activities in the human gut, to have a role in how some bacteria access key nutrients in breast milk.

RNA-protein interactions reveal new coronavirus drug targets

A study led by researchers at the University of California San Diego School of Medicine and University of California, Riverside (UCR) School of Medicine has identified new targets for antiviral drugs against coronaviruses, including SARS-CoV-2, the virus that causes COVID-19.

A hidden structure may explain how infant gut bacteria gets nutrients

This study reveals how a β-sheet cradle in PNGaseABif enhances glycopeptide processing, offering insights into microbial nutrient access in the infant gut.

Can pregnancy leave a lasting mark on biological aging?

A review examines how pregnancy spacing affects maternal aging, proposing that insufficient recovery may lead to cumulative biological aging and health risks.

New dementia risk tool designed for the countries that need it most

An international team led by Northumbria University has developed and validated a simple five-factor risk score to identify older people at elevated risk of dementia in low- and middle-income countries (LMICs) - where around 60% of the world's dementia cases now occur.

Key innate immune protein regulates cholesterol and influences cancer treatment resistance

Scientists at the University of North Carolina Lineberger Comprehensive Cancer Center have discovered an unexpected role for a key innate immune protein, revealing how it helps regulate cholesterol levels inside cells and influences tumor growth and treatment response.

Understanding the causes and treatment of recurring vertigo episodes

Vertigo is a sensation that either you or your surroundings, or both, are spinning or moving when they are not. Some people confuse vertigo with dizziness, but there is a difference, explains Neil Shepard, Ph.D., an audiologist at Mayo Clinic in Minnesota.

A hotter world could have cleaner air, but deadlier heatwaves

Using the extreme heat conditions of 2018–2019, researchers modelled how global warming of 2°C and 2.75°C could affect heatwaves, air pollution and associated mortality across six world regions. The simulations showed increased heatwave-related deaths in every region, particularly South America, while ozone and fine particulate pollution declined in many areas under the higher warming scenario, highlighting contrasting health risks under fixed present-day conditions.

Scientists may have underestimated how much genes contribute to Alzheimer's risk

A large multi-ancestry genetic analysis identified 127 genomic loci associated with Alzheimer's disease, including 48 previously unreported loci, and implicated microglial and neuronal gene-expression patterns in disease susceptibility. The researchers estimated that common genetic variants account for 16% of Alzheimer's disease liability in European-ancestry populations, substantially higher than previous estimates, while demonstrating improved polygenic risk prediction that remained less reliable in non-European populations.
