NewsClimate change portends wider malaria risk as mosquitoes expand range in Africa
Scientists have found that the mosquitoes responsible for transmitting malaria in Africa are spreading deeper into southern Africa and to higher elevations than previously recorded.
-
NewsStudy reveals how drug resistant bacteria secrete toxins
Research suggests that reducing virulence in drug resistant infections rather than trying to kill bacteria outright may offer an answer to antimicrobial resistance.

NewsQuestion mark over claims that trees talk to each other via underground fungi
A University of Alberta expert challenges the idea that forest trees can “talk” to each other, share resources with their seedlings — and even protect them — through a connective underground web of delicate fungal filaments.

NewsExtracts from two wild plants inhibit COVID-19 virus, study finds
Two common wild plants contain extracts that inhibit the ability of the virus that causes COVID-19 to infect living cells, the first major screening of botanical extracts to search for potency against the virus has revealed.

NewsStudy finds link between fungal microbes in infant gut and body weight
Researchers have found a link between the diversity of fungal species in the infant gut and the body-mass index (BMI) of infants.

NewsDose of antibiotic during labour can cut sepsis risk in developing countries
New findings suggest that a single dose of azithromycin given to women planning a vaginal delivery significantly reduces the risk of maternal death or sepsis.

NewsViruses that kill cancer cells show promise for triple-negative breast cancer when combined with chemo
Researchers have shared positive results from a phase 2 clinical trial of an oncolytic virus combined with standard chemotherapy in patients with early stage triple-negative breast cancer.
-
NewsStudy IDs bacterial weapons that could be harnessed to treat human disease
The discovery of ancient immune-fighting machinery in human cells that is derived from bacteria paves the way toward more ‘CRISPR’-like technologies, researchers say.
-
NewsElectrochemical energies yield insights into how bacteria may develop antibiotic tolerance
Researchers investigated variations in the electrochemical energies that power bacterial growth to understand how bacteria develop antibiotic tolerance without acquiring new genes or mutating existing ones.

NewsMicrobes bingeing on burned soil could return land to life after wildfires
Researchers have identified bacteria and fungi that not only survive but thrive during the first year after a wildfire, findings that could help bring land back to life after fires that are increasing in both size and severity. The Holy Fire burned more than 23,000 acres ...

NewsME linked to changes in the gut microbiome and metabolites
Two studies have found that myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is associated with reduced levels in the gastrointestinal microbiome of microbes known to produce the fatty acid butyrate, disruptions that could explain in part how the immune system becomes disrupted in people with ME/CFS.

NewsScientists discover how plastic-eating bacteria digest complex carbons
Researchers have deciphered the metabolic mechanisms that enable the bacterium Comamonas testosteroni to digest complex wasste from plants and plastics, potentially leading to novel biotechnology platforms that harness the microbe to help recycle plastic waste.
-
NewsWorld first study sheds light on why microbes in the deep ocean live without sunlight
A world first study reverses the idea that the bulk of life in the ocean is fuelled by photosynthesis via sunshine, revealing that many ocean microbes in fact get their energy from hydrogen and carbon monoxide.

NewsResearchers uncover link between nutrient availability and diversity of chemosynthetic microbes in Yellowstone hot springs
A new study has uncovered a relationship between nutrient availability and diversity in microbial communities living in Yellowstone hot springs.

NewsNew inoculation based on Ebola VSV vaccine concept protects macaques
Researchers have successfully developed a vaccine against Sudan virus (SUDV) based on the licensed Ebola virus (EBOV) vaccine.
-
NewsHarmful bacteria can elude predators when concealed in mixed colonies
Efforts to fight disease-causing bacteria by harnessing their natural predators could be undermined when multiple species occupy the same space, a new study has revealed.
-
NewsScientists find two separate reservoirs of latent HIV in patients
Scientists have shown that, addition to HIV’s ability to lay dormant in the blood/lymphoid system, the virus may also lay dormant in the central nervous system, delineating another challenge in creating a cure.

NewsWhite-tailed deer carry SARS-CoV-2 variants that are extinct in humans
Researchers have found white-tailed deer – the most abundant large mammal in North America – are harboring SARS-CoV-2 variants that were once widely circulated, but are no longer found in humans.
-
NewsBiorefinery uses microbial fuel cell to upcycle resistant plant waste
Researchers have developed a sustainable, inexpensive two-step process that can upcycle organic carbon waste - including lignin - transforming it into antioxidant flavonoids for nutrition and medicine. .By processing waste through a microbe-driven biorefinery, the researchers turned lignin into carbon sources that could be used in high-value, plant-derived pharmaceuticals and ...

NewsNew vaccine targets life-threatening fungal infections
A new vaccine from the University of Georgia could be the first clinically approved immunization to protect against invasive fungal infections, a growing concern as antifungal drug resistance increases.
