Phytoplasma effector proteins devastate host plants through molecular mimicry

Phytoplasma are a type of bacteria that live within the cells and cause devastating diseases with damaging effects. For example, in many cases plants infected with phytoplasma are no longer able to develop flowers. These plants have actually been described as "zombies," since they allow the reproduction of phytoplasma but are unable to reproduce themselves anymore. A group of biologists based at Friedrich Schiller University and the Fritz Lipmann Institute in Germany are working to help better understand exactly how phytoplasma cells bring about the so-called zombification of plants.

Vampire bats social distance when they get sick

A new paper in Behavioral Ecology, published by Oxford University Press, finds that wild vampire bats that are sick spend less time near others from their community, which slows how quickly a disease will spread. The research team had previously seen this behavior in the lab, and used a field experiment to confirm it in the wild.

Vaping epidemic puts adolescents at risk for potentially fatal lung disease

Adolescent use of e-cigarettes and vaping products is at epidemic proportions, yet the adverse health effects are understudied, with almost no data on younger patients. The problem is sizable as children start vaping at a younger and younger age. Recent estimates show that 9.6 percent of eighth graders vape nicotine or THC (tetrahydrocannabinol, the main active ingredient of cannabis), along with 19.9 percent of 10th graders and 25.5 percent of 12th graders. Many young people vape daily.

Study estimates exposure to air pollution increases COVID-19 deaths by 15% worldwide

Long-term exposure to air pollution has been linked to an increased risk of dying from COVID-19 and, for the first time, a study has estimated the proportion of deaths from the coronavirus that could be attributed to the exacerbating effects of air pollution for every country in the world.
