NewsProtein shuttling mechanism helps bacteria pump out antibiotics
By a joint-university effort, the mechanism of a bacterial efflux pump complex to remove molecules, including antibiotics, has been determined and the extent of bacterial toxin resistance by the complex has also been evaluated with a cutting-edge device.

NewsBacterial cellulose promotes plant tissue regeneration
Researchers have successfully uncovered the molecular mechanisms by which bacterial cellulose patches stimulate the regeneration of plant wounds, offering potential applications in grafting, pruning, and ornamental flower cutting for enhanced plant healing.

NewsDiabetes can drive the evolution of antibiotic resistance, study reveals
A new study shows that people with diabetes are more likely to develop antibiotic-resistant strains of Staph. The results show how the diabetic microbial environment produces resistant mutations, while hinting at ways antibiotic resistance can be combatted in this patient population.

NewsBiosensing platform simultaneously detects vitamin C and SARS-CoV-2
A portable and sensitive biosensing device has been developed by engineering researchers to detect both SAR-CoV-2 and vitamin C simultaneously, to monitor and boost health for the general public.

NewsLong-term yogurt consumption tied to decreased incidence of certain types of colorectal cancer
A new study finds that yogurt consumption over time may protect against colorectal cancer through changes in the gut microbiome. Long-term consumption of two or more servings per week of yogurt was tied to lower rates of proximal colorectal cancer positive for Bifidobacterium.

NewsCold temperatures promote spread of a bird pink eye pathogen at winter feeders
A pathogen for bird pink eye remains viable on bird feeders in winter conditions much longer than in summer conditions without losing any of its severity, according to a study.

NewsStudy reveals direct gut-brain communication via vagus nerve
A new study in an animal model provides direct evidence for the role of the vagus nerve in gut microbiome-brain communication, addressing a critical gap in the field.
-
NewsResearchers engineer biological reaction crucibles to rapidly produce proteins
Biomedical engineers have demonstrated a new synthetic approach that turbocharges bacteria into producing more of a specific protein, even proteins that would normally destroy them, such as antibiotics.

NewsHarvard Pilgrim Health Care Institute announces launch of Center for Sepsis Epidemiology and Prevention Studies (SEPSIS)
The new Center for Sepsis Epidemiology and Prevention Studies (SEPSIS) is a pioneering center of excellence dedicated to advancing understanding, prevention, and management of sepsis, a life-threatening condition caused by a dysregulated immune response to infection.

NewsBlood test eases diagnosis of invasive mold disease
A newly developed blood test, as a non-invasive alternative, could be used to provide a rapid and safe diagnosis for invasive mold infections of the immunocompromised. It can also be applied for other infectious diseases, e.g. tuberculosis.

NewsUncovering two rare infectious diseases which might be responsible for COVID-19
A study has adopted a more-advanced AI technique that revealed two rare infectious diseases might be involved in causing the emergence of COVID-19. The machine learning technique is also important to be used for other biomarker studies.
-
NewsInfluenza A viruses adapt shape in response to environmental pressures
Influenza A virus particles strategically adapt their shape—to become either spheres or larger filaments—to favor their ability to infect cells depending on environmental conditions, according to a new study.
-
NewsScientists recode the genome for programmable synthetic proteins
Synthetic biologists were able to re-write the genetic code of an organism — a novel genomically recoded organism (GRO) with one stop codon — using a cellular platform that they developed enabling the production of new classes of synthetic proteins.

NewsBiochemists discover self-repair function in key photosynthetic protein complex
Receiving too much light can damage the photosystem II protein complex shared by lineages of cyanobacteria, algae and land plants and erode the photosynthetic efficiency of plants. Biochemists have gleaned new details about how photosystem II repairs itself.
-
NewsStudents tackle drug resistance by teaching machine learning
Researchers using machine learning to predict drug resistance in patients have published a step-by-step machine learning tutorial for beginners.
-
NewsTurmeric teamed with light can help ward off superbugs
In a new study, researchers have evaluated a low-cost yet effective technology called photodynamic inactivation using curcumin to curb bacterial resistance.

NewsWhale poo contains iron that may have helped fertilize past oceans
A new study suggests that nutrients that whales excrete may provide a key fertilizer to marine ecosystems. Whale excrement contains significant amounts of iron and nontoxic forms of copper, another essential nutrient that in some forms can harm life.

NewsResearchers glean photosynthetic insights from volcanic hot springs
With the use of mathematic modelling, scientists uncovered the mechanisms of specific algae, such as Cyanidioschyzon merolae, to survive in the extreme environment of acidic hot springs near volcanos.
-
NewsBat genome signposts new potential pathway to fight viruses with genomic characterization
A promising discovery has been made from a study that deciphers how bats are more resistant to viral infections than human using genome annotations of transposable elements in bats to pave a way for adapting the bats’ immunity against future viral outbreaks.
