NewsKeto diet reduces friendly gut bacteria and raises cholesterol levels
The ketogenic diet raises cholesterol levels, particularly in small and medium sized LDL particles, and alters gut microbiome composition, decreasing beneficial bacteria often found in probiotics, a new study reveals.

NewsRed Queen arms race over millions of years preserves genetic diversity in water flea
Host/parasite arms races can occur without interruption over many millions of years, a much longer period than previously thought, according to scientists who compared the genetic material of millimeter-sized water fleas infected by a parasitic bacterium.

NewsSuperbugs spread to family members of recently hospitalized patients
Family members of patients recently discharged from hospital may have a higher risk of getting an antibiotic-resistant infection, even if the patient was not diagnosed with the same infection, suggesting hospitals play a role in community spread of resistant bacteria.
