NewsStudy shows ancient viruses fuel modern-day cancers
When reawakened, endogenous retroviruses can play a critical role in helping cancer survive and thrive. A new study also suggests that silencing certain endogenous retroviruses can make cancer treatments work better.

NewsAncient microbes offer clues to how complex life evolved
A single-celled organism, a close relative of animals, harbors the remnants of ancient giant viruses woven into its own genetic code, shedding light on how complex organisms may have acquired some of their genes.

NewsIntensive farming could raise risk of new pandemics
Intensive livestock farming could raise the risk of new pandemics, researchers have warned. A study examines the effect of social and economic factors – which are often overlooked in traditional assessments.

NewsThe geometry of life: Physicists determine what controls biofilm growth
The fitness of a biofilm is largely impacted by the contact angle that the biofilm’s edge makes with the substrate - and this geometry has a bigger influence on fitness than anything else, including the rate at which the cells can reproduce.

NewsEarly life antibiotic increases risk of asthma: providing clues to a potential prevention adult asthma
Early exposure to antibiotics can trigger long term susceptibility to asthma, according to researchers who isolated a molecule produced by gut bacteria that in the future could potentially be trialed as a dietary supplement for children at risk of asthma.

NewsStudy unveils complexity of zoonotic transmission chains
Researchers have dissected the complex interactions involved in zoonoses, introducing the concept of a “zoonotic web,” a detailed network representation of the relationships between zoonotic agents, their hosts, vectors, food sources, and the environment.

NewsKenyan crop contamination outbreak inspires grad student to improve rice storage
A new study shows that proper rice storage conditions to reduce aflatoxin risk after harvest include a temperature below 20 degrees Celsius, or 68 degrees Fahrenheit, and relative humidity below 75 per cent.

NewsMost Salmonella illnesses from chicken caused by few products with high levels of virulent strains
A new study shows that few products with high levels of very virulent Salmonella strains are responsible for most of the illnesses from raw chicken parts, suggesting regulation efforts should focus on detecting and preventing high-risk contamination.

NewsScientists build roadmap to bioengineer plants that produce their own nitrogen fertilizer
Nitrogen fertilizers make it possible to feed the world’s growing population, but they are also costly, harm ecosystems and require a lot of energy to manufacture. However, a few plants have evolved the ability to make their own nitrogen with the help of bacteria. A new study helps explain how ...
