NewsWhat’s really ‘fueling’ harmful algae in Florida’s lake Okeechobee?
Lake Okeechobee is the largest lake in Florida and the second largest in the Southeastern United States. Over the past two decades, blooms of blue-green algae (Microcystis) have emerged in the lake and have been flushed into nearby urban estuaries, causing serious environmental and public health issues.

NewsScientists discover dual roles of antibodies in COVID-19 infections
A new study has discovered an antibody that can both assist and block a virus. This particular antibody helps pre-Omicron variants of the virus infect cells while preventing the Omicron variant from doing the same.

NewsScientists deploy sound waves as acoustic tweezers to separate viruses from saliva
Researchers have described a platform that uses sound waves as acoustic tweezers to sort viruses from other compounds in a liquid. In demonstrations, the method quickly and accurately separates viruses from large and small particles in human saliva samples.

NewsNew research illuminates the impact of surface properties on bacteria movement
A new study reveals the key role surface properties play in either enabling or preventing twitching motility, the process by which bacteria move across surfaces, allowing them to rapidly colonize new surfaces including those of tissues and medical implants.

NewsDiagnostic tool identifies puzzling inflammatory diseases in kids
A new diagnostic tool can accurately determine if a patient has Kawasaki disease (KD), Multisystem Inflammatory Syndrome in Children (MIS-C), a viral infection or a bacterial infection, while simultaneously monitoring the patient’s organ health.

News‘Ice bucket challenge’ reveals that bacteria can anticipate the seasons
Bacteria use their internal 24-hour clocks to anticipate the arrival of new seasons, according to research carried out with the assistance of an ‘ice bucket challenge’.

NewsFungus uses surface protein of its spores to weaken human immune system
An international research team discovered a special enzyme on the surface of the spores of Aspergillus fumigatus apparently suppresses the release of pro-inflammatory substances by immune cells, making it easier for the pathogen to spread in the tissue.
