10+ hour, 37+ 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…...

2+ day, 14+ hour ago   (1147+ words) Beneath cancer’s genetic chaos, tumor cells may be confined to just a handful of recurring states, revealing a simpler path to treatment. Cancer is often defined by its complexity: countless mutations, shifting cell populations, and tumors that evolve under pressure....

3+ day, 9+ 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…...

4+ day, 13+ 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, 21+ 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…...

5+ day, 19+ 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, 16+ 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…...

1+ week, 1+ day ago   (270+ words) The longer we stay awake, the more certain brain cells appear to turn up the pressure to sleep, eventually making rest nearly impossible to resist....

1+ week, 2+ 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, 3+ day ago   (29+ words) BCL6, a driver of lymphoma, suppresses genes involved in cell death. A new molecule designed at Stanford Medicine blocks BCL6 activity and activates downstream genes that trigger cell death....
