NewsYeast survives Martian conditions, study shows
Life on Mars would have to contend with challenging conditions including shock waves from meteorite impacts and soil perchlorates. Scientists subjected Saccharomyces cerevisiae to these conditions, finding those that survived had assembled RNP condensates.

NewsScientists trace the evolution of the H5N1 virus
Researchers have discovered that the currently circulating 2.3.4.4b clade of H5N1 has specific mutations in its genome that increase its human adaptive potential.

NewsCoveted lac pigment may have a fungal origin
The colourful pigment extracted from the lac insect may actually be produced by a symbiotic yeast-like organism living inside the insect, a new study has found. The yeast-like organism exclusively harbours genes coding for key ingredients in the pigment synthesis pathway.

NewsBacteria deployed to fix cracks in space bricks
Researchers have developed a bacteria-based technique to repair bricks that can be used to build lunar habitats, if they get damaged in the moon’s harsh environment.

NewsAntimicrobial resistance in soil bacteria without the use of antibiotics
Overuse of antibiotics is currently the primary reason for the rise of antimicrobial resistance (AMR), but researchers have shown that AMR can be found in soil bacterial communities due to microbial interactions too, driven by a species of predatory bacteria.

NewsResearchers uncover how bat-origin pathogenic viruses manipulate human cell death and inflammation
A new study offers insights into cell death regulation by viruses like SARS-CoV-2, and how bats and humans respond differently to tricks that such viruses use to manipulate the host’s defense.

NewsBreaking down bacterial barriers using bovine gut enzyme
A team of scientists has devised a way to break down biofilms which limit the entry of drugs and help bacteria become resistant to antibiotics, using an enzyme from the cow’s digestive tract.

NewsNovel 3D hydrogel culture to study TB infection and treatment
Researchers have designed a novel 3D hydrogel culture system that mimics the mammalian lung environment, providing a platform to track and study how tuberculosis bacteria infect lung cells and test the efficacy of therapeutics used to treat TB.

NewsScientists probe spermidine production to combat emerging drug resistance in Salmonella
Scientists have pinpointed how Salmonella Typhimurium uses a key molecule called spermidine to shield itself from the onslaught of the host’s defence machinery - and an existing FDA-approved drug can reduce spermidine production.

NewsResearchers track the virus behind India’s lumpy skin cattle crisis
A study provides critical insights into the evolution and origins of the virus strains fueling a devastating outbreak of lumpy skin disease, which has severely affected India’s agricultural sector, leading to staggering economic losses.

NewsPaper-based platform offers rapid detection of antibiotic-resistant bacteria
A paper-based platform could help quickly detect the presence of antibiotic-resistant, disease-causing bacteria.

NewsResaerchers design thermostable vaccine candidate for SARS-CoV-2 variants
Researchers report the design of a synthetic antigen that can be manufactured as a potential COVID-19 vaccine candidate - it is effective against all current strains of SARS-CoV-2 and can be quickly adapted for future variants as well.

NewsPicolinic acid reveals its broad-spectrum antiviral abilities
Picolinic acid, a natural compound produced by mammalian cells, can block several disease-causing viruses such as SARS-CoV-2 and influenza A viruses, according to a new study.
