NewsGut bacteria transfer genes to disable weapons of their competitors
New research shows how common gut bacteria tame their antagonistic neighbors by transferring genes that change their weapon systems.

NewsBacteria and fungi found on bat wings that could help fight deadly white-nose syndrome
Bacteria and fungi from the wings of bats could play a significant role in saving them from white-nose syndrome (WNS), a fungal disease affecting the skin of wings and muzzle, which has nearly wiped out vulnerable bat populations across North America.

NewsA metabolic secret of ethane-consuming archaea unraveled
Scientists have presented a study on the degradation of ethane, the second most abundant alkane in seeps on the deep seafloor. They characterized enzymes involved in the process and found that their reaction breaks an established dogma in the field of anaerobic biochemistry.

NewsLyme borreliosis: New approach for developing targeted therapy
A research team has made significant progress in understanding the mechanism of Lyme borreliosis infection and identified a potential way forward for the development of targeted therapies that do not rely on antibiotics.

NewsUnnoticeable electric currents could reduce skin infections
Using a few zaps of electricity to the skin, researchers can stop bacterial infections without using any drugs. For the first time, researchers have designed a skin patch that uses imperceptible electric currents to control microbes.

NewsAntibiotics and antifungals may slightly affect Parkinson’s risk, study finds
A study has found that people who took multiple courses of penicillin antibiotics had a modestly lower risk of developing Parkinson’s disease, a surprising finding that researchers say highlights the complex relationship between bacteria in the digestive tract and brain health.

NewsNative fungus could offer biocontrol for invasive autumn olive
Researchers are studying a native fungus that potentially could kill the invasive autumn olive with minimal human interaction.To remove the autumn olive currently, the plant needs to have its underground root system removed in addition to the destruction of the plant itself, but this fungus could make this process much easier.

NewsStudy yields evidence of oldest confirmed photosymbiosis in corals
Researchers have demonstrated, using nitrogen isotope analyses, that some extinct corals from the Middle Devonian period were already symbiotic. This represents geochemical evidence of the oldest confirmed photosymbiosis in corals.

NewsMaternal antibodies interfere with malaria vaccine responses
Maternal antibodies passed across the placenta can interfere with the response to the malaria vaccine, which would explain its lower efficacy in infants under five months of age, according to research.

NewsNew tool enables a more complete and rapid decoding of the language of algal gene expression
A new method that research teams can use to measure and compare different forms of proteins and protein complexes helped reveal a previously unseen molecular signature of how algal genomes are controlled during the cell cycle.

NewsRepeated COVID vaccines enhance mucosal immunity against the virus
New work has found that repeated Covid-19 vaccinations lead to the presence of mucosal antibodies, for example, inside the nose.

NewsPolar bears’ exposure to pathogens is increasing as their environment changes
As the Arctic warms, polar bears now face a greater risk of contracting several pathogens than bears three decades ago, a new study reveals.

NewsNovel antibody platform tackles viral mutations
Scientists have developed an innovative antibody platform aimed at tackling one of the greatest challenges in treating rapidly evolving viruses like SARS-CoV-2: their ability to mutate and evade existing vaccines and therapies.

NewsFull-bodied cheese flavor–prediction of flavor development soon possible thanks to new method
Peptides formed during cheese ripening are crucial for the full-bodied flavor of aged cheeses, known as kokumi. Researchers have now developed a new method to analyze these flavor-relevant peptides precisely, quickly, and efficiently.

NewsTire-wear particles disrupt gut-liver function in aquatic organisms
Researchers have uncovered the adverse health effects of tire-wear particles (TWPs) on aquatic organisms. The study focused on the hepatotoxicity of TWP leachates, revealing significant impacts on the gut-liver axis and oxidative stress levels in test organisms.

NewsResearchers probe parasite transmission in turkey flocks
As scientists learn more about a deadly parasite’s ability to move from host to host in turkey flocks, a long-standing theory is in question and opens the door to new preventative measures. Source: U of A System Division of Agriculture photo Histomonosis is a deadly disease to turkeys. ...

NewsStudy reveals how our gut cells detect harmful invaders
Researchers hve found that the GPR31 path in ‘gut surveillance’ cells detects bacterial metabolites and triggers immune responses, opening new possibilities for drug development, vaccines, and probiotics to fight infections.

NewsFloor swabbing could help prevent COVID-19 outbreaks in hospitals
In two Ontario hospitals, high levels of SARS-CoV-2 on floors correlated with COVID-19 cases among healthcare workers and patients, suggesting floor swabbing as a potential method to prevent outbreaks.

NewsPlastic mulch is contaminating agricultural fields
Using plastic sheets for weed control, even under current best management practices, pollutes soil with macro- and micro-plastics and negatively affect critical soil functions, according to a study.
