Ancient DNA reveals how a chicken virus evolved to become more deadly

Published on December 8, 2023

An international team of scientists led by geneticists and disease biologists from the University of Oxford and LMU Munich have used ancient DNA to trace the evolution of Marek's Disease Virus (MDV). This global pathogen causes fatal infections in unvaccinated chickens and costs the poultry industry over $1 billion per year. The findings, published today in the journal Science, show how viruses evolve to become more virulent and could lead to the development of better ways to treat viral infections.

Study shows diverse gut bacteria communities protect against harmful pathogens by nutrient blocking

December 8, 2023
A new study led by the University of Oxford has demonstrated that diverse communities of resident bacteria can protect the human gut from disease-causing microorganisms. The researchers found that protective communities block the growth of harmful pathogens by consuming nutrients that the pathogen needs. The findings, published today in the journal Science, could help to develop new strategies to

Study finds that vast amounts of waste are caused by single-use e-cigarette batteries

December 8, 2023
While the lithium-ion batteries in disposable electronic cigarettes are discarded after a single use, they can continue to perform at high capacity for hundreds of cycles, according to new research from the University of Oxford and UCL, supported by The Faraday Institution. The study, published today in Joule, highlights a growing environmental threat from these increasingly popular vape pens, whi
