19+ hour, 49+ min ago   (832+ words) Some proteins that vanished millions of years ago may still have something to teach scientists about fighting modern infections. University of Oregon biologists have reconstructed antimicrobial molecules dating back as far as 160 million years, and laboratory tests showed that some…...

3+ day, 18+ 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…...

5+ day, 6+ hour ago   (714+ words) Australian researchers have identified a promising new approach that could help stop one of the most aggressive forms of breast cancer from spreading. Triple-negative breast cancer becomes especially dangerous once tumor cells escape the breast and establish themselves elsewhere in…...

6+ day, 4+ 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…...

6+ day, 17+ hour ago   (434+ words) A hidden molecular defect in inflammatory bowel disease may help explain why flare-ups can return even when patients appear well....

1+ week, 1+ day ago   (464+ words) A microbial metabolite called 3,4 dihydroxybenzoic acid, derived from dietary fiber, improved antitumor immunity in mice. A compound made by gut bacteria during the breakdown of dietary fiber may offer a way to strengthen cancer immunotherapy. In mouse studies, University of…...

1+ week, 3+ day ago   (678+ words) Newly identified CHL1 fibroblasts may help lung cancers escape immune attack by recruiting regulatory T cells around tumors. A previously unknown population of fibroblasts appears to help lung tumors hide from the immune system by drawing suppressive T cells to the…...

1+ week, 4+ day ago   (411+ words) A new study finds that as people age, they remember fewer details from their past and have more difficulty switching between different types of memories....

1+ week, 5+ day ago   (623+ words) A study found a new mitochondrial pathway in senescent cells that alters how DNA is stored, exposing genes linked to inflammation. Inflammation is essential when the body needs to fight an infection or repair an injury. But the same protective…...

1+ week, 6+ day ago   (640+ words) By analyzing three different types of brain scans, researchers uncovered new clues about the biological processes linked to autism. The results point to the dopamine system as a potentially important part of autism biology. Autism is associated with differences across…...
