Holder vs Retort: How milk pasteurization shapes preterm infants’ gut health

Researchers at Vanderbilt University Medical Center found that pasteurization methods shape the gut microbiomes of preterm infants fed donor human milk. Holder pasteurization preserved microbial diversity and beneficial taxa better than Retort, producing microbiomes more similar to those from mothers’ own milk.

Innovative biosensor can detect airborne viruses in real time

A research team from Universitat Politècnica de València (UPV) and Universitat de València (UV) has developed an innovative biosensor capable of detecting airborne viruses in real time and at low cost, without the need for chemical markers or laboratory procedures.

Study reveals how ozone exerts multi-organ effects by disturbing the lung-liver connection

Ozone pollution is rising worldwide, frequently exceeding safety thresholds in urban centers and industrial regions. Its health risks are well-documented: breathing ozone can worsen asthma, damage airways, and increase the risk of cardiovascular and neurological disorders.

Soap shortages undermine global hand hygiene efforts

A lack of soap is the most often reported barrier to effective hand hygiene-key to curbing the spread of infection-in shared community spaces, such as households, schools, and public places, finds a systematic review of the available research, published in the open access journal BMJ Global Health.

Study uncovers the tradeoff between fast immune defense and long-term inflammation

Some of our biggest threats can come in the tiniest forms-viruses and bacteria. Thankfully, we are born with a built-in defense system, our innate immune system that protects us in our youth but can turn against us as we age.

Ketogenic diets may lower migraine frequency and medication use

This narrative review argues that the migraine brain is hypometabolic, with converging evidence of mitochondrial dysfunction, impaired glucose handling, neuroinflammation, microbiome shifts, and obesity-related pathways. It proposes ketogenic diets as a plausible preventive strategy that may reduce monthly migraine days and medication use, while emphasizing the need for larger, rigorous randomized trials and careful clinical oversight.

Unlocking hidden soil microbes for new antibiotics

Most bacteria cannot be cultured in the lab-and that's been bad news for medicine. Many of our frontline antibiotics originated from microbes, yet as antibiotic resistance spreads and drug pipelines run dry, the soil beneath our feet has a vast hidden reservoir of untapped lifesaving compounds.

Bacteria use density switch to balance virulence and growth

Pathogens are becoming more and more resistant to antibiotics. With the goal of developing new therapeutic approaches to treat bacterial infections more effectively in the future, researchers at the Karlsruhe Institute of Technology (KIT) and the Max Planck Institute in Marburg investigated the plague-related bacterium Yersinia enterocolitica.
