Heated tobacco and cigarettes cause the same gut and vascular damage, study finds

Italian researchers found that both heated tobacco products (HTPs) and conventional cigarettes trigger oxidative stress, endotoxemia, and gut barrier disruption in adults and children. The findings challenge the perception that HTPs are a safer alternative to smoking.

Exploring the link between underweight status and gut microbiota composition in Japanese women

Low body weight in young women has been linked to a range of health concerns, including disrupted menstrual cycles, infertility, weakened immune function, and a long-term decline in bone density.

Scientists capture a near-continuous molecular movie of ribosome formation

Ribosomes are the cell's protein factories, which read the genetic code and assemble the proteins that every organism needs to live. But as far as how ribosomes themselves were formed, tantalizingly little was known.

Two microbial metabolites compete to control the cells' protein building machinery

The microbiome-the trillions of bacteria, viruses, and fungi that live quietly in our body-plays a crucial role in shaping human health by providing a variety of micronutrients necessary for vital functions.

Babies' gut bacteria could play a role in programming brain circuits tied to emotional health

A child's early gut microbiome may influence their risk of developing depression, anxiety or other internalizing symptoms in middle childhood, according to a new UCLA Health study.

Some acute and chronic viral infections linked to increased risk of cardiovascular disease

In the weeks following a bout of influenza or COVID, the risk of heart attack or stroke may rise dramatically, and chronic infections such as HIV may increase the long-term risk of serious cardiovascular disease events, according to new, independent research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

New biofilm discovery may pave way to undermining antibiotic-resistant Pseudomonas

The bacterium known as Pseudomonas aeruginosa is an unwelcome visitor in the human body. Serious infections can result when a bunch of these bugs settle together on a surface to form a biofilm - a community of microbes like the slime on spoiled food, but in this case residing inside a person.

Purdue researchers develop 30-second vaccine quality tool

The outbreak of the COVID-19 pandemic demonstrated the need to rapidly develop, produce and distribute large quantities of new vaccines. A team of researchers at Purdue University and Merck & Co. Inc., known as Merck Sharp & Dohme Corp. outside of the U.S. and Canada, has now introduced a new analytical tool that could help pharmaceutical companies boost vaccine production with rapid monitoring and analysis.

Scientists uncover the gut’s hidden hydrogen engine and how it falters in Crohn’s disease

Study reveals that group B [FeFe]-hydrogenase is the primary enzyme driving fermentative hydrogen production in the healthy human gut, mainly through Bacteroides species. These genes are significantly depleted in Crohn’s disease, indicating a metabolic shift and altered hydrogen cycling dominated by respiratory bacteria

Lack of essential amino acid prompts animals to seek out protein-rich yeast and gut bacteria

New research from the Champalimaud Foundation (CF) reveals how missing just one essential amino acid can change gene expression and the brain's sensory systems, prompting animals to seek out protein-rich yeast and gut bacteria that help them restore nutritional balance and survive in times of need.
