| How bacteria adhere to fiber in the gut Posted: 28 Aug 2020 08:53 AM PDT Researchers have revealed a new molecular mechanism by which bacteria adhere to cellulose fibers in the human gut. Thanks to two different binding modes, they can withstand the shear forces in the body. |
| Using math to examine the sex differences in dinosaurs Posted: 26 Aug 2020 05:07 PM PDT When you only have fossils to go off of, it's hard to tell which dinosaur traits, like size and ornamentation, are related to the animals' sex, and which traits are related to other things like age. But a new kind of statistical analysis can often estimate the degree of sexual variation in a dataset of fossils. |
| Catching genes from chlamydiae allowed complex life to live without oxygen Posted: 26 Aug 2020 11:13 AM PDT Researchers has discovered a new group of Chlamydiae - named the Anoxychlamydiales - living under the ocean floor without oxygen. These have genes that allow them to survive without oxygen while making hydrogen gas. The researchers found that our single-cell ancestors 'caught' these hydrogen-producing genes from ancient Chlamydiae up to two-billion years ago - an event that was critical for the evolution of all complex life alive today. |
