1+ hour, 54+ min ago   (77+ words) For decades, entomopathogenic fungi have earned their reputation the hard way: by infecting and killing insects. Species such as Beauveria bassiana and Metarhizium anisopliae have been formulated as biological pesticides that attach to the insect cuticle, breach the exoskeleton and…...

1+ hour, 59+ min ago   (82+ words) Pseudomonas aeruginosa, a Gram-negative bacterium that thrives everywhere from hospital water systems to contact lens solutions, is one of the most formidable opportunistic pathogens in modern medicine. The World Health Organization has placed it on its high-priority list of bacteria…...

18+ hour, 18+ min ago   (709+ words) Ancient DNA reveals that plague repeatedly returned to Europe for more than 400 years after the Black Death, evolving into new lineages and spreading through trade, migration, and war. Researchers also developed a method to date ancient plague genomes more precisely,…...

18+ hour, 17+ min ago   (561+ words) Chitosan is a linear polysaccharide obtained by deacetylation of chitin, which is naturally present in the exoskeletons of crustaceans, insect cuticles, and the cell walls of certain fungi. Its favorable biological properties, combined with a highly adaptable chemical structure, have…...

1+ day, 23+ hour ago   (69+ words) A research team has identified a purified fucoidan fraction from the edible brown alga Laminaria japonica that shows strong anti-allergic activity in laboratory cell models. The fraction, known as LJF-2, was enriched in sulfate groups, uronic acids, and rhamnose and…...

2+ day, 6+ hour ago   (221+ words) ATLANTA — University of Georgia researchers have identified 19 viruses in Atlantic and Pacific sea turtles, including seven novel viruses, that may pose a risk to threatened and endangered sea turtles. Scientists in UGA’s College of Veterinary Medicine used genetic sequencing to…...

2+ day, 9+ hour ago   (433+ words) Sarah Kuta | Daily Correspondent Sheep pox is a highly contagious, often fatal disease that can devastate entire herds. Now, scientists have found traces of the virus in historic manuscripts, suggesting that it has been plaguing European farmers for thousands of…...

2+ day, 6+ hour ago   (311+ words) While these numbers describe statistical variance across a population rather than an individual diagnostic score, they point to gut microbes as a clearer indicator of biological health. One profile, known as the Bacteroides 2 enterotype, was marked by lower overall bacterial…...

2+ day, 10+ hour ago   (363+ words) Using genetic sequencing, scientists have identified 19 viruses - including seven never seen before in any species – in Atlantic and Pacific sea turtles, giving researchers a baseline to track emerging disease threats. Scientists at the University of Georgia have identified previously unknown…...
