2+ day, 7+ hour ago   (429+ words) New findings raise questions about the role of microbes living in the lungs. More than 35 trillion bacteria live throughout the human body, forming microbiomes in the gut, mouth, lungs, skin, and urogenital tract. Researchers increasingly recognize that these microbial communities…...

3+ day, 3+ hour ago   (119+ words) Using a new computational toolkit, Yale researchers recovered evolutionary clues from highly degraded DNA and identified two extinct lineages of giant tortoises....

3+ day, 10+ hour ago   (356+ words) An unusual immune signature in lung cancer has led researchers toward a potential therapy involving tumor microbes and MAIT cells. Bacteria living inside lung tumors may be doing more than simply occupying the tumor environment. In preclinical research from the…...

4+ day, 3+ hour ago   (752+ words) MIT researchers have engineered bacteria to behave like transistors, making it possible to build living “circuit boards” that can be printed onto growth material in a Petri dish. In conventional electronics, transistors act as switches that control whether electrical current…...

4+ day, 16+ hour ago   (745+ words) A bacterial molecule called gladiolin can disarm invasive Candida albicans and strengthen the effects of a major antifungal drug. The findings were published in Current Biology, and emerged from the Monash Warwick Alliance Programme in Antimicrobial Resistance (AMR), a long-term…...

4+ day, 17+ hour ago   (1279+ words) Bats’ remarkable ability to withstand decades of strenuous flight while keeping infections, inflammation, and cancer in check may offer new clues to healthier human aging Bats are unusually long-lived for animals of their size. Small mammals generally burn energy quickly…...

5+ day, 13+ hour ago   (564+ words) Many things change in space, including how the intestines function. Constipation is a known side effect of space travel, but until now, little has been known about why it happens. Constipation is a familiar problem for astronauts, but the biological…...

6+ day, 17+ hour ago   (408+ words) Enamel proteins from Homo erectus teeth suggest genetic links to Denisovans while offering a less destructive way to study ancient human fossils. A handful of ancient teeth may preserve clues to a relationship that has remained difficult to trace through…...
