NewsResilient algae may speed up Greenland ice melt
Microscopic algae darken glacier surfaces and can accelerate melting. A new study investigating where the small algae get the necessary nutrients to survive in this hostile environment reveals how they absorb and store nutrients.

NewsCoffee grounds and Reishi mushroom spores can be 3D printed into a compostable alternative to plastics
Researchers have developed a new system for turning coffee grounds into a paste, which is inoculated with Reishi mushroom spores to form a mycelial skin. The skin turns the coffee grounds into a resilient, fully compostable 3D printable alternative to plastics.

NewsExpedition confirms spread of highly pathogenic avian influenza virus in the Weddell Sea
The CSIC-UNESPA scientific expedition monitoring the presence of the highly pathogenic avian influenza virus (HPAI H5N1) in Antarctica has confirmed the presence of the virus in all species detected on six islands in the Weddell Sea.

NewsNovel antibiotic BTZ-043 also reaches tuberculosis bacteria hiding in dead lung tissue
Researchers have shown that the novel antibiotic BTZ-043 effectively penetrates tubercolous lesions and accumulates there in high concentrations. Consequently, the drug can fight Mtb bacteria even in hard-to-reach areas.

News1 in 5 older adults get infections after heart surgery, and women have a 60% higher risk
One in five older adults gets an infection up to six months after heart surgery, with women far more likely to develop one, according to two studies which examined thousands of cases of coronary artery bypass grafting.

NewsResearchers ID key immune differences that make one West African ethnic group less susceptible to malaria
Researchers have uncovered how genetic and lifestyle factors influence immune responses to malaria in children from two large West African ethnic groups. Children showed key differences in immune cell activity offering greater protection.

NewsScientists unveil novel anti-CRISPR protein mechanism
Apart from their counter-defensive function, anti-CRISPR proteins hold great promise for enabling more precise control over CRISPR technologies. Researchers have now further elucidated the function of an important yet so far uncharacterized anti-CRISPR protein.

NewsNo more antibiotics? Scientists pioneer a safer way to protect cultured meat
A new study explores the use of Random Antimicrobial Peptide Mixtures (RPMs) as a safe and effective alternative to antibiotics in cultured meat production. These synthetic peptide cocktails eliminate bacterial contamination without harming stem cell viability or contributing to antibiotic resistance.

NewsResearchers uncover how Staphylococcus aureus ‘steals’ iron from our blood during infections
Researchers have revealed how Staphylococcus aureus bacteria extract iron from hemoglobin – a process crucial to their survival during infections. The study has identified the full sequence of protein–protein interactions during this iron ‘theft’.

NewsScientists develop new natural killer cell strategy to target HIV
Scientists have successfully identified a new approach using natural killer (NK) cells to target and kill the HIV-positive cells that allow the virus to persist. They genetically modified NK cells to express CD64, a protein not normally expressed by NK cells.
