| How do blind cavefish survive their low-oxygen environment? Posted: 11 Mar 2022 03:25 PM PST Cavefish have obvious adaptations such as missing eyes and pale colors that demonstrate how they evolved over millennia in a dark, subterranean world. Now researchers say these incredible fish have an equally remarkable physiology that helps them cope with a low-oxygen environment that would kill other species. |
| Scientists make leap forward for genetic sequencing Posted: 11 Mar 2022 03:25 PM PST Researchers reveal new details about a key enzyme that makes DNA sequencing possible. The finding is a leap forward into the era of personalized medicine when doctors will be able to design treatments based on the genomes of individual patients. |
| How to make the TB vaccine more effective Posted: 11 Mar 2022 11:14 AM PST Briefly blocking a key molecule when administering the only approved vaccine for tuberculosis vastly improves long-term protection against the devastating disease in mice, researchers report. |
| Mirror image biomolecule helps marine sea squirts lose their tails Posted: 11 Mar 2022 11:14 AM PST Researchers have found that D-serine, the structural mirror image of L-serine, regulates tissue migration in the marine organism Ciona during its juvenile-to-adult transformation. D-serine binds to NMDAR, leading to the formation and release of a vesicle that assists in tail regression in Ciona. This finding provides the first description of a biological function of a D-amino acid in a non-mammal chordate, elucidating vesicle release mechanisms in organisms other than mammals. |
| Firefly luminescence reveals pesticides Posted: 11 Mar 2022 06:53 AM PST A luminescence reaction modeled on fireflies can detect contamination with organophosphates with high sensitivity, ease, and low cost. At the center of this technology is a new enzymatic method for the synthesis of analogues of luciferin, the substance that makes fireflies glow. As reported by a team of researchers, it could also be used in the field. |
| Past global photosynthesis reacted quickly to more carbon in the air Posted: 10 Mar 2022 11:37 AM PST Ice cores allow climate researchers to look 800,000 years back in time: atmospheric carbon acts as fertilizer, increasing biological production. The mechanism removes carbon from the air and thereby dampens the acceleration in global warming. |
