NewsScientists develop eco-friendly, nylon-like plastic using microorganisms
Scientists have developed microbial strains through systems metabolic engineering to produce various eco-friendly, bio-based poly(ester amide)s from glucose derived from biomass sources such as waste wood and weeds.

NewsHepatitis B: new rapid diagnostic test to halt mother-to-child transmission
Scientists have assessed a new rapid diagnostic test to identify pregnant women at elevated risk of transmitting hepatitis B to their babies. This diagnostic tool could help eliminate hepatitis B by preventing mother-to-child transmission during childbirth.

NewsCorrecting imbalance with the gut microbiota after stroke could reduce brain inflammation
An imbalance in ligands, which are molecules produced by the body and the gut microbiota, can affect a key receptor protein that plays a role in brain inflammation after stroke, according to researchers.

NewsMeasles elimination versus eradication: The difference explained
As of March 13, the CDC has confirmed 301 cases of measles as well as the death of a child in Texas. Amira Roess, an epidemiologist and professor of global health, clarifies the benefits of vaccinating children and adolescents against measles.

NewsAntibiotic exposure in infancy may boost Type 1 diabetes risk - but microbiota can help
Exposure to antibiotics during a key developmental window in infancy can stunt the growth of insulin-producing cells and may boost risk of diabetes later in life. But the research pinpoints specific microbes that may help those critical cells proliferate in early life.

NewsThe gut microbiota-metabolites-brain axis mediates social behavior dysfunction following anaesthesia
New research shows that the anaesthetic Sevoflurane (Sev) influences social functioning via the gut-brain axis, with microbiota-derived bile acids serving as critical mediators in this pathway.

NewsTadpoles try to flee dangerous virus in their pond by growing much faster than normal
A new study shows that larvae of wood frogs respond to the presence of a deadly ranavirus by growing and maturing precociously. In response to ranavirus, tadpoles change their growth, development, and resource allocation, which may help them tolerate the energetic demands of infection or escape risky environments to avoid infection.

NewsC. diff uses toxic compound to fuel growth advantage
The pathogen C. diff — the most common cause of health care-associated infectious diarrhea — can use a compound that kills the human gut’s resident microbes to survive and grow, giving it a competitive advantage in the infected gut.

NewsGrowing body of evidence links HPV with heart disease
In addition to causing several types of cancer, human papillomavirus (HPV) appears to bring a significantly increased risk of heart disease and coronary artery disease, according to a study.

NewsProbe into human cervical stem cells shows lactic acid bacteria can prevent cervical cancer
Researchers have revealed the identity and differentiation process of human cervical stem cells in a world first study. The results showed that lactic acid bacteria can inhibit the development of cervical cancer.

NewsResearchers achieve de novo biosynthesis of plant lignans using synthetic yeast consortia
Researchers have achieved the biosynthesis of the antiviral ingredient lignan glycoside in yeast Saccharomyces cerevisiae. By mimicking the spatial and temporal regulation of plant biosynthesis, they designed a system with obligated mutualism, enabling metabolic division of labor among different yeast strains.

NewsSusceptibility to bovine TB in cattle traced to key genes
A new study identifying genetic factors contributing to bovine tuberculosis (bTB) susceptibility has found several key genes and pathways involved in the bovine response to Mycobacterium bovis, the causative agent of the disease in cattle.

NewsNewer hepatitis B vaccine shows promise as booster for health care workers
A new study compares the effectiveness of Heplisav-B, a new hepatitis vaccine, vs. standard hepatitis B vaccines as a booster in previously vaccinated individuals.

NewsEvaluating DNA impurities in recombinant adeno-associated virus
A new study indicates that DNA impurities derived from plasmid and host cell DNA are encapsulated into recombinant adeno-associated virus (rAAV) capsids as single-stranded DNA.

NewsBiogenic construction: The new era of civil engineering
Inspired by the concept of harmonious coexistence between humans and nature, a new concept, biogenic construction, for civil engineering is proposed in a new paper.

NewsNew study reveals a safer alternative for long-term hepatitis B treatment
Researchers have studied the effects of switching from long-term tenofovir disoproxil fumarate to the antiviral besifovir dipivoxil maleatein (BSV) in patients with chronic hepatitis B. Switching to BSV may improve patient kidney and bone health.

NewsRapid and accurate diagnosis of urinary tract infections using targeted next-generation sequencing
A study shows that tNGS demonstrates advantages in rapid and accurate UTI diagnosis, particularly in detecting polymicrobial infections and analyzing antibiotic resistance genes. It shows promise as an effective complementary tool for UTI diagnostics.

NewsBreaking antibiotic-resistant bacteria’s protective shields opens door for immune system response
Researchers have made progress in uncovering how Streptococcus pneumoniae constructs its capsule, which serves as a protective shield. This capsule is a primary target for vaccine development.

NewsStudy evaluates airborne transmission risk of mpox compared to COVID-19 and smallpox
Scientists have found that the inhaled infectious dose of mpox is at least 100 times lower than that of SARS-CoV-2 and smallpox, making efficient respiratory aerosol transmission highly unlikely in its current form - but future viral evolution could alter this dynamic.

News‘Low-sugar’ vaccine can provide broad immunity against coronavirus variants
A universal vaccine for coronaviruses removes sugar molecules from an area of a coronavirus spike protein that rarely mutates and creates effective and plentiful antibodies to inactivate the virus.
