NewsGut microbiome fluctuates through days and seasons
The balance of microbes in the human gut varies substantially from morning to night and even more by season, with profound fluctuations completely transforming the microbiome from summer to winter, a new study reveals.
-
NewsSensor controls how dormant bacteria reawaken
Researchers have discovered a new kind of cellular sensor that allows spores to detect the presence of nutrients in their environment and quickly spring back to life.
-
NewsMonoclonal antibody programme targets mucormycosis
Vitalex Biosciences has been awarded an SBIR Phase 2 grant from the National Institute of Allergy and Infectious Diseases (NIAID) at the National Institutes of Health for VX-01, a monoclonal antibody (mAB) programme targeting the debilitating indication of the fungal disease, mucormycosis.

NewsAntimicrobial foam targets bugs or oil spills
A versatile new foam material could significantly reduce health care-related infections caused by implanted medical devices - or drastically improve cleanup efforts following environmental disasters like oil spills.
-
NewsLiving yeast-based dual biosensor detects peptides
The state-of-the-art biosensor with a visible readout could have potential applications in virus detection, diagnostics, and other areas.
-
NewsNew method may harness radiation-resistant bacterium
Researchers find a novel way to expand applications of the hardy bacterium Deinococcus radiodurans, using gene deletion techniques.

NewsStool transplants more effective than antibiotics for treating recurring, life-threatening gut infections
A new Cochrane Review has found that, compared with standard antibiotic treatment, stool transplantation can increase the number of people recovering from Clostridioides difficile infection from 40% to 77%.
-
NewsNew biologic effective against major infection in early tests
Researchers have shown in early tests that a bioengineered drug candidate can counter infection with Staphylococcus aureus – a bacterial species widely resistant to antibiotics and a major cause of death in hospitalized patients.
-
NewsInfectious SARS-CoV-2 isolated from hospital air samples
Scientists have succeeded in isolating infectious particles of the SARS-CoV-2 virus from air samples collected from hospital rooms of COVID-19 patients and kept frozen for more than a year, a new study shows.

News‘Antibiotic culture’ permeates US hospital ICUs, study finds
A new study reveals that there continues to be an ’antibiotic culture’ in US hospitals, meaning that the preference for antibiotics is related to their perceived role as ’magic bullets’.
-
NewsMassive Caribbean sea urchin die-off caused by unicellular parasite
Scientists have discovered a parasite is behind a severe die-off of long-spined sea urchins across the Caribbean Sea, which has had devastating consequences for coral reefs and surrounding marine ecosystems.
-
NewsFirst rapid test for mpox can be tailored for other emerging diseases
The first rapid test for mpox has been developed - the selective molecular sensor can detect the virus within minutes, without the use of any high-end instrumental techniques.
