NewsResearch shows feasting fungi could revolutionize carbon-fiber recycling
Researchers have developed a chemical procedure for breaking down and removing the matrix from carbon fiber reinforced polymers such that recovered carbon fiber plies exhibit mechanical properties comparable to those of virgin manufacturing substrates.

NewsWild bird's gut microbiome linked with its sexual ornamentation and body condition
A new study provides the first description of how a wild bird’s microbiome relates to its ornamentation and body condition. A Northern cardinal’s gut microbiome diversity can be predicted by its body condition, and the quality of its ornamentation – red plumage and beak.

NewsFirst full characterization of kidney microbiome unlocks potential to prevent kidney stones
Low levels of bacteria like E. coli and Lactobacillus in our urine come from communities in our kidneys, where they promote or prevent kidney stone formation.

NewsStudy shows how genetic defects in Toxoplasma are rescued by co-infection
Toxoplasma gondii parasites can use secreted factors to compensate for genetic defects in neighbouring parasites, highlighting a limitation of pooled CRISPR screens.

NewsUpdated Hep B vaccine more effective for people with HIV
A newer vaccine against hepatitis B virus was clearly superior to an older vaccine type in inducing a protective antibody response among people living with HIV who didn’t respond to prior vaccination, according to an international study.

NewsEl Niño increases infestations of mosquito that transmits dengue in São Paulo state, Brazil
A study by a group of scientists shows that larval infestations of Aedes aegypti in open-air disused containers increased in response to the effects of the weather phenomenon.

NewsNew study reveals how COVID-19 variants hijack human cells
A research team has successfully mapped what they call the “hijackome”, detailing how SARS-CoV-2 variants exploit specific cellular pathways.

NewsNew review highlights variant-specific differences in long COVID
Alpha and Delta variants have been linked to a higher prevalence of cardiopulmonary symptoms, such as breathlessness and chest pain, while Omicron infections show fewer severe cardiopulmonary effects but relatively higher incidences of fatigue and brain fog.

NewsAround 1 in 5 of the world’s under 50s living with genital herpes (HSV)
Around 1 in 5 of the world’s under 50s—846 million people—are living with genital herpes infection, and more than 200 million 15-49 year olds probably had at least one symptomatic outbreak of the infection in 2020, suggest the latest global estimates.

NewsToxoplasma gondii parasite uses unconventional method to make proteins for evasion of drug treatment
A new study sheds new light on how Toxoplasma gondii parasites make the proteins they need to enter a dormant stage that allows them to escape drug treatment.

NewsUnusual endosymbionts crop up all over the world
Scientists have discovered peculiar mitochondria-like symbionts all over the world, and unveiled their surprising metabolic capacities in a new study.

NewsPossible colon cancer vaccine target uncovered in bacteria
Higher rates of certain cancers may be linked to two particular strains of bacteria. Targeting these with treatments or vaccines could help reduce the risk of colorectal, bladder, and prostate cancers.
-
NewsStudy offers insight into chloroplast evolution
Researchers have found evidence suggesting that the primary role of primitive chloroplasts may have been to produce chemical energy for the cell and only later shifted so that most or all of the energy they generated was used for carbon assimilation.

NewsStudy reveals how ‘Conan the Bacterium’ withstands extreme radiation
Deinococcus radiodurans can withstand radiation doses thousands of times higher than what would kill a human - and scientists have uncovered the secrets of the antioxidant that confers this protection.

NewsTiny poops in the ocean may help solve the carbon problem
Zooplankton could capture carbon dioxide originating from Earth’s atmosphere and deposit it deep into the sea as feces. The new technique mooted consists of spraying clay dust on the surface of the ocean at the site of large blooms of phytoplankton.

NewsClimate change could bring more severe bacterial infections, including in corals
A new study shows that climate warming can potentially make bacterial and fungal infections deadlier for cold-blooded animals like corals, insects, and fish, raising questions about the broader risks warming temperatures pose to ecosystems and biodiversity—and potentially humans.
