NewsFrom Asgard to Earth: tiny discoveries hold clues to life’s greatest leap
Stromatolites may hold insights into how complex life began. Researchers have identified a previously unknown microbe living in close partnership with another organism inside these ‘living fossils’.

NewsResearchers explore potential link between COVID-19 and lung cancer risk
New findings have identified a potential association between COVID-19 and increased lung cancer risk, driven by underlying biological mechanisms in the lung. The study integrates human clinical data with mechanistic research in animal and cellular models.

NewsNanodisc platform improves vaccine design for Ebola, HIV and more
Scientists have created a platform that allows viral surface proteins to be studied in a form that more closely resembles how they appear naturally, utilizing nanodisc technology where these proteins are embedded into particles made of lipid molecules, preserving them in a membrane-like structure.

NewsNative bacteria may break down dioxins without genetic modification
Researchers have demonstrated that native soil bacteria, when treated with decoy molecules, can degrade non-native compounds, including persistent pollutants such as dioxins, without genetic modification.

NewsTrial assesses safety and effectiveness of two new TB vaccines
Two new vaccines to prevent tuberculosis (TB) are safe for use in adults and children, but they do not offer protection against all forms of TB, finds a large trial from India.

NewsNon-producing oil and gas wells emit microbial methane at rates 1,000 times higher than previously estimated
Microbial methane leaking from non-producing oil and gas wells is being emitted at rates about 1,000 times higher than previously estimated, according to a new study.

NewsHow cholera bacteria swap defenses against viruses
To survive viral attack, bacteria equip themselves with antiviral immune systems. Vibrio cholerae carries a large genetic element called a sedentary chromosomal integron (SCI). A new study investigates whether the SCI might capture gene cassettes from genetic material entering the cell from the outside.

NewsCould your housemates be changing your gut bacteria?
Living with friends may quietly be altering your gut bacteria - according to a new study. Research on a colony of tiny island birds reveals they share more of their gut bacteria with the birds they spend the most time with.

NewsMethod for amplifying the full genome of human papillomavirus 16 uses overlapping extension polymerase chain reaction
Human papillomavirus (HPV) is a double-stranded circular DNA virus with a genome of approximately 7–8 kb. A new study aims to establish an overlapping extension polymerase chain reaction method for the amplification of the entire genome of HPV16.

NewsHidden ocean feedback loop could accelerate climate change
Scientists have uncovered a key mechanism behind methane production in the open ocean. Their research indicates that this mechanism could intensify as the planet warms, providing an alarming feedback loop for global warming.

NewsTropical trees are more neighborly, study suggests
Tropical trees are better neighbors than trees in temperate forests, according to a new study. Trees growing closer to the equator have more positive interactions with their neighbors, which may help explain why tropical forests are home to so many tree species.

NewsImmunogenicity and safety of an Escherichia coli-produced 9-valent HPV vaccine in adolescents compared with young women
Based on new findings, the National Medical Products Administration of China has approved a two-dose immunization schedule for the domestically produced 9-valent HPV vaccine in girls aged 9 to 17 years.

NewsAtomic-level structure of a giant virus revealed
Researchers have successfully determined, for the first time, the capsid structure of Melbournevirus—a member of the giant virus family—at a resolution of 4.4 Å using cryo-electron microscopy.

NewsRethinking the gut microbiome: Health is not about staying the same
Despite decades of research into the gut microbiome, microbiome-based interventions such as probiotics or fecal transplants still produce inconsistent results. Scientists suggest part of the problem may lie not in the microbiome itself, but in how we define what it means to be ‘healthy’.

NewsAfrican swine fever: a novel model for assessing transmission between domestic pigs and wild boar
Researchers have developed an innovative multi-host epidemiological model for African swine fever incorporating both pig farms and wild boar habitats and calibrated using empirical outbreak data. The model uses detailed data from the first phase of the Romanian epidemic.

NewsEnzyme produced by fungus may replace chemicals in the paper industry
Fungal xylanase can be obtained by cultivating the microorganism in sugarcane bagasse or wheat bran. The solution is a non-polluting alternative for bleaching cellulose pulp, which currently uses a toxic chemical.

NewsA smarter way to build vaccines: scientists harness AI to target emerging alphaviruses
Scientists have developed a new computational pipeline that could dramatically accelerate the development of vaccines against a group of mosquito-borne viruses known as alphavirus.

NewsRapid and visual on-site detection system for Epizootic Hemorrhagic Disease Virus
Epizootic Hemorrhagic Disease (EHD), a vector-borne disease affecting both wild and domestic ruminants, is transmitted by biting midges of the genus Culicoides. Researchers developed a rapid and visual test strip for EHDV RNA detection based on RT-ERA and CRISPR-Cas12a.

NewsPueraria lobata decoction-derived vesicle-like nanoparticles reveal a novel mechanism for ulcerative colitis treatment
By simulating the traditional decoction process, researchers successfully isolated structurally intact GGD-PDVLNs from dried Pueraria lobata after boiling. These nanoparticles demonstrated remarkable stability in simulated gastric acid and intestinal fluids.

NewsAstragalus polysaccharide-linked exosomes “wake up” latent HIV-1 by flipping a key cellular switch
“Shock-and-kill” strategies aim to reactivate latent virus so infected cells become visible to immune clearance or additional therapies. In a new study, researchers investigated whether exosomes could mediate HIV latency reversal after exposure to Astragalus polysaccharide (APS).
