NewsBiological patterns: Stability through protein reservoirs
Biophysicists have figured out how bacteria form robust patterns despite changing environmental conditions and fluctuating protein concentrations.

NewsNew CDC nPEP Guidelines should become ‘part of general medical practice’
Health experts say the updated CDC HIV Non-Occupational Post Exposure Prophylaxis (nPEP) Guidelines should be part of general medical practice, as incorporating them will reduce new HIV infections and improve public health.

NewsFruit and microbes boost biogas production and fermentation
Researchers have reported on a new recipe for improving biogas production from alfalfa. Adding fruit waste and an anaerobic microbe to the mix first leads to co-fermentation, then produces methane.

NewsInvasive rats and rainforest mammals are sharing gut microbes as urban areas grow
As urban development continues to creep further into Earth’s oldest and most diverse rainforests, a study reveals native and invasive small mammals aren’t just adapting to their changing habitats—they may also be sharing their microbes.
-
NewsElectricity-generating bacteria may power future innovations
Scientists have discovered how certain bacteria breathe by generating electricity, using a natural process that pushes electrons into their surroundings instead of breathing on oxygen.

NewsClinical trial underway for potential Long COVID treatment
A clinical trial is underway to assess the effectiveness and safety of sipavibart, AstraZeneca’s long-acting monoclonal antibody designed to provide protection against Covid-19, as a potential treatment for Long Covid.

NewsDancing plant cells defeat Pseudomonas - and win international competition
The University of Jena, Germany has won the renowned ’Dance your PhD’ competition in the category Biology with its video “Plant Vaccination”. The video visualizes the thesis of Jena doctoral candidate Priya Reddy with dancers and original choreography.

NewsConsumption of ultra-processed foods by children up to one year old favors harmful bacteria in the gut
Analysis of the gut microbiota of more than 700 babies also showed that breastfeeding was a protective factor, mitigating the problem in those who consumed industrialized products. The study underscores the importance of breastfeeding.

NewsUrban rats spread deadly bacteria as they migrate, study finds
Urban rats spread deadly bacteria as they migrate within cities that can be the source of a potentially life-threatening disease in humans, according to a six-year study that also discovered a novel technique for testing rat kidneys.

NewsScientists introduce new engineered drug candidate for Mycobacterium abscessus to save lives
Scientists have introduced a promising drug candidate engineered to target a deadly and emerging infection. They took a hyper-detailed look into the problem of Mycobacterium abscessus, and chemically re-engineered a widely-used rifamycin antibiotic.
-
NewsThe solution for microbial communities to survive environmental stress is self-sufficiency
Researchers have shown, based on an experimental system that reproduces a mutualistic microbial community, that the most common evolutionary solution for two co-dependent organisms to survive extreme environmental change could be to become self-sufficient.
-
NewsResearch advances on ‘displacing’ antibiotic resistance gene from bacteria
Scientists have identified essential genetic code for a method called plasmid curing, which aims to ‘displace’ antibiotic resistance genes from bacteria.
-
NewsUltimate self-sacrifice: Bacteria activate unusual defense to evade viral attack
Scientists discover that the restriction modification system in some bacteria can kill the cell as a last resort if viruses try to thwart it. They trigger their own death using components of the very same systems that the phages were trying to inhibit.
-
NewsAI plays detective to help scientists find hidden microbes
A team of researchers has created a novel machine learning tool that’s cracking open one of biology’s trickiest puzzles: finding the rarest microbes on Earth. Ulrb not only identifies rare microorganisms but also works with non-microbial data.

NewsTopical gel relieved ear infections in animals after just one dose
Researchers report a topical antibiotic gel that, applied once, cured middle ear infection within 24 hours in chinchillas. a single dose of treatment for middle ear infections could improve patient compliance and potentially reduce pediatric antibiotic usage.
-
NewsScientists launch intranasal albumin-based vaccine technology platform against respiratory virus
A new paper reports on a novel vaccine technology platform, in which the subunit antigen is genetically fused to albumin. The albumin-antigen fusion vaccines induced both systemic and mucosal antigen-specific antibody responses.
-
NewsNew molecular label could lead to simpler, faster tuberculosis tests
Chemists have demonstrated that they can label a glycan called ManLAM using an organic molecule that reacts with specific sulfur-containing sugars. These sugars are found in only three bacterial species, including the microbe that causes TB.
-
NewsPlacebo-testing vaccines is unethical, ‘a waste of time and money,’ expert says
The proposal to require that all new vaccines undergo safety testing in placebo-controlled trials is ethically problematic and will slow testing down for no good reason, warn scientists.

NewsAntibodies that recognize lipids: A new path for HIV vaccines and autoimmune disease treatments
Scientists have used computer modeling to illustrate how a specific class of antibodies actually use lipids to recognize the HIV virus. The work highlights antibody features that could help people design better vaccines for HIV and autoimmune diseases.

NewsScientists uncover the link between ‘good’ gut bacteria and rheumatoid arthritis
After spending years tracing the origin and migration pattern of an unusual type of immune cell in mice, researchers have shown how activity of “good” microbes in the gut is linked to rheumatoid arthritis and, potentially, other autoimmune diseases.
