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.

NewsBartonella and babesia co-infection detected in patients with chronic illness
A small pilot study has found evidence of human co-infections from Bartonella and Babesia odocoilei, a protozoal tick-borne infection primarily found in deer, moose and other cervids.

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.

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.

NewsScientists ID ‘unconventional’ new pathway for TB vaccines
Marginal zone B (MZB) cells are a natural response to TB infection which has been long overlooked - and which might be a welcome new target.
-
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 ...

NewsReceptors make dairy cows a prime target for influenza
Researchers who examined mammary gland samples from two cows infected with highly pathogenic avian influenza found a rich supply of sialic acid, which could shed light on how the virus attaches to hosts and help develop measures to slow the spread.

NewsHibernation status matters when white-nose syndrome pathogen infects bats
The fungal pathogen that causes white-nose syndrome (WNS) in bats uses different cell entry strategies depending on the host’s hibernation status – cold and inactive, or warm and active.
