NewsScientists uncover risk factors for long Covid
A study has found that people with a milder Covid-19 infection—including those who were vaccinated against SARS-CoV-2 and those who were infected with an Omicron variant—were more likely to recover quickly.

NewsGiant deep-sea vent tubeworm symbionts use two carbon fixation pathways to grow at record speeds
New research sheds light on how a giant hydrothermal vent tubeworm living in the deep ocean coordinates the two functional carbon fixation pathways used by its symbiotic bacteria to sustain themselves and their host.

NewsInfectious H5N1 influenza virus in raw milk rapidly declines with heat treatment
The amount of infectious H5N1 influenza viruses in raw milk rapidly declines with heat treatment, but small amounts of infectious virus remain in raw milk samples with high virus levels when treated at 72 degrees Celsius for 15 seconds.

NewsPowdery mildew loves city living - scientists investigate why
Weeds in the city had significantly more mildew than the weeds in the suburbs or countryside, discovers a team that tracked infestations of powdery mildew on common broadleaf weeds.

NewsBerberine could treat eczema-exacerbated staph infections
Eczema, a skin inflammatory disease that causes dry, itchy and inflamed skin, affects millions worldwide. Eczema is associated with an altered skin microbiome and higher colonization by Staphylococcus aureus. Source: NIAID/NIH Scanning electron micrograph of methicillin-resistant Staphylococcus aureus(MRSA, brown) surrounded by cellular debris. A new study, ...

NewsIntranasal COVID-19 vaccine headed to clinical trials
CyanVac will sponsor a randomized, double-blind Phase 2b study to compare the efficacy and safety of CVXGA, its intranasal vaccine candidate designed to protect against COVID-19, against an FDA-approved mRNA-based COVID-19 vaccine.

NewsAI enables faster, more effective antibiotic treatment of sepsis
Sepsis is a life-threatening infection complication and accounts for 1.7 million hospitalizations and 350,000 deaths annually in the U.S. Fast and accurate diagnosis is critical, as mortality risk increases up to 8% every hour without effective treatment. Source: Ilanaer42 However, the current diagnostic standard is reliant on ...

NewsScientists unravel drivers of the global zinc cycle in our oceans
The important role of the Southern Ocean in global biological processes and the carbon cycle has been confirmed by a study that, for the first time based on field evidence, reveals the underappreciated role of inorganic zinc particles in these cycles.

NewsPlant bacteria deploy phage elements to wipe out the competition
A new study has found that plant bacterial pathogens are able to repurpose elements of their own phages to wipe out competing microbes, suggesting such elements could someday be harnessed as an alternative to antibiotics.

NewsSyphilis cases are rising, but many people don’t know the symptoms
Syphilis cases are on the rise around the globe, but many Americans don’t know the symptoms. Just over half know that a case of syphilis can be permanently cured and most either mistakenly think there is a vaccine to prevent it or are unsure.

NewsScientists adapt astronomy method to unblur microscopy images
To make adaptive optics more widely available to biologists, researchers have turned their attention to a class of techniques called phase diversity that’s been widely used in astronomy but is new to the life sciences.

NewsScientists identify key pathogen targets to tackle black rot in sweetpotato
A new study identifies 31 Ceratocystis fimbriata effector genes and suggests a biotrophic phase, in which the fungus lives off living sweetpotato storage roots before killing it, providing a new perspective on how the disease progresses.

NewsIngestible microbiome sampling pill technology takes a step forward
Significant progress has been made in the development of a small device, about the size of a vitamin pill, that can be swallowed and passed through the gastrointestinal tract to sample the full inventory of microorganisms.

NewsSafer virus helps eliminate cancer and protect against future tumors
Scientists have discovered that an attenuated (weakened) virus can help eliminate cancer in mice. In addition, mice that were treated with this virus were more resistant to developing tumors later in life.

NewsTwo types of polymicrobial infections in chronic lung diseases
Chronic lung diseases are often accelerated and exacerbated by polymicrobial infections. An international study team led by MedUni Vienna has identified two types of these so-called dysbioses in cystic fibrosis. They display distinct ecology and are also likely to respond differently to treatment. The study was published in the journal ...

NewsSoil bacteria respire more CO2 after sugar-free meals
Researchers have tracked the pathways of a mixture of plant waste as it moves through bacteria’s metabolism to contribute to atmospheric CO2. Microbes respire three times as much CO2 from lignin carbons compared to cellulose carbons, they say.
