NewsHigh-efficacy adjuvanted subunit vaccine against variant infectious bursal disease virus in chicks
Infectious bursal disease (IBD) is an acute, highly contagious disease caused by the infectious bursal disease virus (IBDV), primarily affecting chicks. Notably, the emergence of new mutant strains that exacerbate the disease can cause serious economic losses to the global poultry industry. To date, there is no commercial vaccine against ...

NewsNew study brings vaccine hopes for deadly Nipah virus
Researchers have tested experimental Nipah vaccines in pigs, aiming to cut off the virus at one of its key transmission routes. The study describes the development of three vaccine candidates using different viral surface proteins.

NewsMicrobially synthesized bioplastic may solve marine plastic pollution problem
Researchers have demonstrated a new eco-friendly plastic that decomposes in deep ocean conditions. In a deep-sea experiment, the microbially synthesized poly(d-lactate-co-3-hydroxybutyrate) (LAHB) biodegraded, while conventional plastics persisted.

NewsCertain fungi can boost the micronutrient content of bread wheat
New research indicates that bread wheat’s micronutrient content can be increased by cultivating it with a specific type of fungus. Crops grown with the arbuscular mycorrhizal fungus Rhizophagus irregularis developed larger grains with greater amounts of phosphorus and zinc.

NewsCan a compound produced by deep-sea bacteria treat cancer?
Investigators purified a long-chain sugar molecule, or exopolysaccharide, from deep-sea bacteria and demonstrated that it triggers pyroptosis—an inflammatory form of programmed cell death—to inhibit tumor growth.

NewsVitamin D deficiency increases risk of COVID-19 hospitalization
Experts say it’s not just booster shots that could offer protection against Covid-19 – healthy levels of vitamin D may also play a role. Researchers found a clear link between low vitamin D levels and an increased risk of being hospitalised by the virus.

NewsCo-infections in young bats could underpin coronavirus emergence
A new study finds that young bats are infected more frequently by coronaviruses and could be a key source of viral spillover into other species. It also reveals the dynamics of coronaviruses circulating in Australian bats, which pose no known risk to humans.

NewsStudy identifies world-first treatments to prevent a life-threatening virus infection
A study found two HIV antivirals already on the market can suppress transmission of HTLV-1 in humanised mice and prevent disease. When used in combination with a compound that induces cell death, infected cells were killed – flagging a potential future curative strategy.

NewsFermented stevia leaf extract has potential as anticancer treatment, researchers find
Stevia may provide more benefits than as a zero-calorie sugar substitute. When fermented with bacteria isolated from banana leaves, stevia extract kills off pancreatic cancer cells but doesn’t harm healthy kidney cells, according to a research team.
