First report of cotton blue disease in the United States
Reported from six counties in coastal Alabama in 2017, cotton blue disease affected approximately 25% of the state's cotton crop and caused a 4% yield loss. The disease was reported again in 2018, affecting 3-100% of cotton fields in Alabama but causing only a 1% yield loss. Symptoms, which include slowed plant growth, loss of chlorophyll, and dwarfing of infected leaves, usually do not appear until last August after full bloom. To date, there are no recommended strategies for management of this disease.

Researchers discover a new principle — how cells protect themselves from mitochondrial defects.
Read moreLifestyle is a threat to gut bacteria: Ötzi proves it, study shows
The evolution of dietary and hygienic habits in Western countries is associated with a decrease in the bacteria that help in digestion. These very bacteria were also found in the Iceman, who lived 5300 years ago, and are still present in non-Westernized populations in various parts of the world. The depletion of the microbiome may be associated with the increased prevalence, in Western countries, of complex conditions like allergies, autoimmune and gastrointestinal diseases, obesity.
Preventing streptococci infections
Researchers have discovered an enzyme they believe could be key to preventing Group A Streptococcus infections that cause more than 500,000 deaths worldwide each year. The enzyme works through a novel mechanism of action that can also be found in other streptococcal species, increasing the impact and relevance of this finding.

Scientists have found a new species of choanoflagellate. This close relative of animals forms sheets of cells that 'flip' inside-out in response to light, alternating between a cup-shaped feeding form and a ball-like swimming form. The organism could offer clues about animals' early evolution.

Scientists discover that a brain region known to control sex and violence contains rare cell types that differ in male versus female mice.

Scientists have isolated a natural chemical that acts as a potent kryptonite against parasitic worms that burrow through human skin and cause devastating health problems. Researchers now describe the successful characterization of this chemical, which could help in finding new ways to fight the neglected tropical disease schistosomiasis.
