NewsTracking melanoidins to improve food-waste biogas recovery
Higher pretreatment temperatures in food-waste biogas recovery can promote Maillard reactions, generating melanoidins. A study shows that melanoidins increase with hydrothermal temperature and inhibit methane production by disrupting methanogenic microbial communities.

NewsAntibiotic use for uncomplicated diverticulitis remains widespread despite guideline shifts
A retrospective cohort study found that antibiotic prescribing rates for outpatient cases of uncomplicated diverticulitis remain above 95%, despite guidelines from 2015 recommending more selective use.

NewsAlgae microbots take aim at bladder cancer
Tiny algae-based robots guided by magnets could improve bladder cancer treatment by boosting delivery of chemotherapy drugs into tumours. Tracked using real-time imaging, the miniature robots help drugs penetrate deep into tumour tissue while limiting damage to healthy cells.

NewsMovement of “forever chemicals” through the Great Lakes
New analysis of 42 years worth of biological records from the Great Lakes, unveils how per- and polyfluoroalkyl substances (PFAS) or “forever chemicals” have moved across the region, contaminating a variety of wildlife.

NewsCaught in the act: A gene jumps into the void
Self-splicing introns are a special group of jumping genes. It is more difficult for a gene to jump into another cell or another species. Until now, it had been assumed that, for this to happen, the jumping genes travelled as ‘hitchhiker’ in the genomes of plasmids or viruses, but researchers have made a surprising observation.

NewsUrgent hot tub health warning as Britain prepares to sizzle
As Britain prepares to sizzle with temperatures expected to reach 37°C in some areas over the next four days, water experts are warning that a potentially deadly disease can thrive in hot tubs, pools and other domestic water devices.

NewsLow risk of global spread of Ebola disease, analysis suggests
Researchers identified and analysed all known Ebola disease cases outside Africa to assess the risk of undetected Orthoebolavirus transmission outside Africa and to put it into context with possible border and travel policies.

NewsHow H5N1 bird flu hid unrecognized for weeks in dairy cattle
A new study reveals why H5N1 influenza infection looked so different in dairy cows, offering a framework for spotting new host species quickly. Instead of affecting the lungs, it caused severe infection in the cows’ udders, largely sparing the lungs.

NewsOropouche virus has already infected more than 5 million people in Brazil, study suggests
The recent Oropouche virus outbreak in 2023 has drawn attention in Brazil and other Latin American countries because of its scale and rapid spread. Researchers estimate that since 1960, the virus has infected approximately 9.4 million people in Latin America and the Caribbean.

NewsNew study shows near-complete reduction of cervical cancer deaths among HPV-vaccinated adolescents in England
A new study suggests the Human Papilloma Virus (HPV) vaccine may be responsible for a near-complete protective effect against death from cervical cancer among women under 30 in England who received the vaccine between 12-18 years old.
