NewsEndophytes colonize and protect coffee seedlings
Fungi found living within the tissue of plants from old growth forests in Costa Rica can colonize coffee seedlings and protect them from disease, a new study has revealed.

NewsTraditional medicine plant could combat drug-resistant malaria
Researchers have identified compounds in the leaves of a particular medicinal Labrador tea plant used throughout the First Nations of Nunavik, Canada, and demonstrated that one of them has activity against the parasite responsible for malaria.

NewsAncestral mitoviruses discovered in mycorrhizal fungi
A new group of mitochondrial viruses confined to the arbuscular mycorrhizal fungi Glomeromycotina may represent an ancestral lineage of mitoviruses.

NewsSecond gene implicated in malaria chloroquine resistance evolution
How malaria parasites evolved to evade a major antimalarial drug has long been thought to involve only one key gene. Now, scientists have shown a second key gene is also involved in malaria’s resistance to the drug chloroquine.

NewsAntiscalants for desalination membranes may contain bacteria-boosting chemicals
Identifying the components of membrane antiscalants that cause biofouling could help make seawater desalination a more sustainable source of fresh water, scientists say.

NewsAI strategies already boosting sepsis cure rate
An artificial intelligence developed at TU Wien (Vienna) can suggest appropriate treatment steps in cases of blood poisoning.
-
NewsProchlorococcus ancestors rafted out to sea on chitin particles
Scientists propose that ancestors of Prochlorococcus hitched a ride on passing exoskeleton particles, using the particles as rafts to venture further out to sea. These chitin rafts may have also provided essential nutrients, fueling and sustaining the microbes along their journey.

NewsBacteria can switch from rare earth metals to radioactive elements
Scientists have demonstrated for the first time that bacteria can use certain radioactive elements to sustain their metabolism.

NewsBacteria evolve antibiotic resistance quickly by rejigging pumps
Bacteria can rapidly evolve resistance to antibiotics by adapting special pumps to flush them out of their cells, according to new research from the Quadram Institute and University of East Anglia.

NewsWine yeast species may be communicating during fermentation - using extracellular vesicles
A new study of what happens when two different wine yeast starter species are combined suggests that they could be communicating - and that extracellular vesicles may play a role in that communication.

NewsPostal HPV kits boost cervical screening uptake
At-home high-risk human papillomavirus (hrHPV) sampling kits can help increase cervical cancer screening among under-screened women from low-income backgrounds, according to findings from a US-based clinical trial.

NewsInter-species interactions may stymie antibiotics
A new study suggests that between-species interactions within the gut microbiome may impact the efficacy of antibiotics aimed at treating C. difficile infections.

NewsEye drops cause infection long before CDC warning
A patient was diagnosed with a dangerous Pseudomonas aeruginosa eye infection caused by contaminated eye drops, months before the CDC issued warnings against using the product.
-
NewsTobacco plant engineered to act as drug factory
Researchers have engineered a close relative of tobacco, Nicotiana benthamiana, to churn out peptides with antibiotic activity against some of the nastiest pathogens known to medicine.
-
NewsScientists ID microbes that associate with oilcane
Researchers have identified the types of microbes that associate with engineered oilcane, opening the way to new opportunities to leverage plant-microbial interactions in these feedstocks, which could increase oil yields for sustainable bioenergy production.
-
NewsAfrican rhinos have retroviruses not found in their cousins
New research reveals that the genomes of African rhinos contain dozens of gammaretroviruses that are absent from the genomes of Asian rhino species, such as the Sumatran and Javan rhino, and the African black rhino has two related groups, one missing from the white rhinos.

NewsYeast evolves into multicellular life in the lab
A fascinating long-term evolution experiment has seen model organism ’snowflake yeast’ adapt into multicellular individuals more than 20,000 times larger than their ancestor.
-
NewsProtein may pave way to eliminating HIV latency
Researchers have identified and characterized Schlafen 12 (SLFN 12) as a novel HIV restriction factor that shuts down viral protein production and helps virus-infected cells to escape from anti-HIV therapy and immune responses.

NewsSleep supplement impairs action of gut microbiota
Despite its antioxidant effects and role in regulating sleep cycles, tests show melatonin can worsen inflammation of the intestine and impair the action of gut microbiota.

NewsIcy microbes digest plastic at low temperatures
Scientists have found microbes that can digest plastics at low temperatures, potentially saving money and energy.
