NewsMicroorganisms can travel long distances in the troposphere
Air samples taken at altitudes up to 3,000 metres over Japan unveil the presence of a wide array of microbes, some of which are potentially pathogenic to humans, transported thousands of kilometers by aerosols originating in northeast China.

NewsScientists unveil tactics of how viruses move through insects for transmission of diseases
Researchers have uncovered the clever tactics viruses use to spread through their insect hosts and potentially infect other animals. This knowledge is particularly crucial for combating viruses that spread from insects to humans or livestock.

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.

NewsAn antidiabetic helps the immune system recognize reservoirs of HIV
Metformin, a drug used to treat type 2 diabetes, could help deplete the viral reservoir and eliminate it entirely in people living with HIV who receive antiretroviral therapy, a new study reveals.

NewsEmergency department screening more than doubles detection of syphilis cases
Providing optional syphilis tests to most people seeking care at a large emergency department led to a dramatic increase in syphilis screening and diagnosis, according to a study of nearly 300,000 emergency department encounters in Chicago.

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.

NewsExtreme microbe reveals how life’s building blocks adapt to high pressure
An AI tool has helped scientists discover how the proteins of a heat-loving microbe respond to the crushing conditions of the planet’s deepest ocean trenches, offering new insights into how building blocks of life might have evolved under early Earth conditions.

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.

NewsScientists close in on mystery of deadly Hep C virus
A new study by a cross-disciplinary research team has identified the protein complex at the surface of the hepatitis C virus that enables it to bind to human cells, opening a pathway to vaccine candidates that can prevent the virus from infecting the cells.

NewsPerfect protection - melanins are particularly important for lichens
Researchers have found evidence in the genome of a newly named lichen that an unusually large proportion of its polyketide synthases are likely responsible for the production of melanins, which protect lichens from excessive sunlight.

NewsFish gut microbes might play a role in future skin care products
Researchers have found molecules from fish gut bacteria that can inhibit tyrosinase and collagenase enzymes in lab-grown mouse cells, making them promising anti-wrinkle and skin-brightening agents for future cosmetic products.
