NewsAncient DNA reveals how a chicken virus evolved to become more deadly
Scientists have used ancient DNA to trace the evolution of Marek’s Disease Virus (MDV), showing how viruses evolve to become more virulent and could lead to the development of better ways to treat viral infections.

NewsDiverse gut bacteria communities protect against harmful pathogens by nutrient blocking
A new study demonstrates that diverse communities of resident bacteria can protect the human gut from disease-causing microorganisms. However, this protective effect is lost when only single species of gut bacteria are present.

NewsNew understanding of ancient genetic parasite may spur medical breakthroughs
Scientists have published the first high-resolution images and structural details of a virus-like element known as LINE-1, describing it as “an ancient genetic parasite” that is one of the most common parts of human DNA.

NewsBreastfeeding alters infant gut in ways that boost brain development, may improve test scores
A study of the infant ‘fecal metabolome’ suggests that nursing, including part-time while supplementing with formula, yields significant brain-health benefits.

NewsGut bacteria of malnourished children benefit from key elements in therapeutic food
Researchers investigating a new therapeutic food aimed at repairing malnourished children’s underdeveloped gut microbiomes has identified key, naturally occurring biochemical components and the important bacterial strains that process these components.

NewsScientists reveal rare enzyme role change with bacterial defense system assembly
A never-before-seen phenomenon in a protein: alone, the enzyme processes DNA and RNA but, when bound to another protein as part of a defense system, interacts with a completely different type of compound to help bacteria commit suicide.

NewsMpox vaccine triggers equally strong immune response in smaller doses
Delivering the two-dose mpox vaccine in smaller than the usual FDA-approved doses produced a detectable immune response. This also occurred regardless of whether people were living with or without HIV.

News Researchers develop a novel dry-powder inhaled vaccine platform
Researchers have developed a single-dose, dry-powder, inhalable vaccine platform using nano-micro composite multilevel structures, which is effective in blocking respiratory viral infection and transmission in animal models.
