NewsViral persistence and serotonin reduction can cause long COVID symptoms
Components of the SARS-CoV-2 virus remain in the gut of some long COVID patients, causing persistent inflammation, vagus nerve dysfunction, and neurological symptoms.

NewsFungal infection in the brain produces changes like those seen in Alzheimer’s disease
Researchers have discovered how the fungus Candida albicans enters the brain, activates two separate mechanisms in brain cells that promote its clearance, and generates amyloid beta (Ab)-like peptides.

NewsResearchers awarded $2m to create carbon-negative ‘living’ construction materials
Researchers are working towards a future when homes and other buildings can be constructed using low-cost, sustainable materials that also can repair themselves and capture carbon dioxide from the atmosphere.

NewsClinical trial finds live vaccinations safe for liver and kidney transplant recipients
Live vaccinations provided to children who previously received liver or kidney transplants were found to be safe and prompted an immune response to guard against several life-threatening conditions.

NewsBat immune genes protect against COVID and cancer
Bats have acquired remarkable traits throughout their evolution. They’re the only mammals that can fly, and they live much longer than other animals their size. But perhaps most impressive is their robust immune system. It protects bats from viruses that wreak havoc in humans, like COVID-19 or Ebola, and also ...

News Targeting a coronavirus ion channel could yield new Covid-19 drugs
Chemists discover the structures of open and closed states of the channel, which could help the development of antiviral drugs to reduce inflammation.
-
NewsStudy reveals how inner machinery of yeast cells responds to stress
Researchers have combined state-of-the-art imaging techniques to see how cells conserve energy and pick up where they left off after heat shock.

NewsEngineered bacteria paint targets on tumors for cancer-killing T cells to see
Columbia engineers are the first to program bacteria to act as beacons that guide the activity of engineered T cells. This work is also the first to design interactions between these two “living” medicines to enable targeting of a range of solid tumor.

NewsStudy reveals how young children’s immune systems tame SARS-CoV-2
A study of infants and young children found those who acquired SARS-CoV-2 had a strong, sustained antibody response to the virus and high levels of inflammatory proteins in the nose but not in the blood.
-
NewsResearchers ID genes that correlate with early colonization in fecal microbe transplants
Researchers found 19 Bacteroides vulgatus genes that were unique to three strains that show early engraftment in patients after a fecal transplant, as opposed to seven strains that did not show early engraftment.

NewsOld Faithful Geyser environment promotes genomic diversity
More strains of extremophile Thermocrinis are found in Old Faithful than in any other non-geysing hot spring in Yellowstone, suggesting that the dynamic environment promotes genomic diversity.

NewsEngineered bacteria guide CAR-T cells to poorly infiltrated solid tumors
A new probiotic-guided chimeric antigen receptor (CAR)-T platform uses engineered bacteria to infiltrate and produce synthetic antigen targets, enabling CAR-T cells to find, identify, and destroy tumor cells in situ, according to a new study.

NewsUsing different flours for sourdough fosters different bacteria – and flavours
A new study of the microbial ecosystem in sourdough finds that using different types of flour fosters distinct bacterial communities, and that these differences contribute to the variation of sourdough aromas and flavours.
