Resisting wheat rust in Texas
Wheat is vulnerable. Among the most damaging diseases that affect wheat crops across the world are rusts. These parasites cannot grow without infecting a host plant, and are responsible for some of the greatest destructions of crops in human history. Breeders have recently released a cultivar of winter wheat -- TAM 305 -- that is resistant to many of the rust fungi.

Wastewater treatment plants not responsible for spreading antimicrobial resistance
Wastewater contains remnants of antimicrobial agents and a variety of pathogenic bacteria. It has therefore been generally assumed that wastewater treatment plants are the ideal location for pathogenic bacteria to develop new resistance genes. New research challenges the common perception that bacteria develop antimicrobial resistance in wastewater treatment plants.

Vaginal microbes influence whether mucus can trap HIV
HIV particles are effectively trapped by the cervicovaginal mucus from women who harbor a particular vaginal bacteria species, Lactobacillus crispatus. The findings could lead to new ways to reduce or block vaginal transmission of HIV and other sexually transmitted infections.

Wheat choice has lasting effect on soil health and yield
Scientists investigating how to control take-all, a fungus that lives in soil and infects wheat roots to cause disease, have discovered that different varieties of wheat have distinct and lasting impacts on the health of the soil in which they are grown.
