| Posted: 24 May 2022 07:05 AM PDT Mustelids are the most ecologically and taxonomically diverse family within the order Carnivora. From the tayra in the neotropics to the wolverine in the subarctic, they inhabit a variety of ecological niches and developed corresponding species-specific traits related to their diet, reproductive strategy and morphology. An international team of scientists conducted a comparative analysis of whole genomes of several mustelids to obtain insights into the molecular basis of these adaptations. |
| Cystic fibrosis: Restoring airway integrity Posted: 24 May 2022 07:05 AM PDT Cystic fibrosis is a rare genetic disease which can cause very serious symptoms. In particular, patients suffer from chronic bacterial infections that can lead to respiratory failure. It is caused by mutations in the CFTR gene, which regulates water movement across the cell membrane. Consequently, mucus quality is altered, it is no longer capable of capturing undesirable bacteria and expelling them. Using a model reproducing a respiratory epithelium -- a protective tissue composed of a monolayer of cells -- scientists have discovered that a simple film of liquid is sufficient to restore the airways' seal and reduce the risk of bacterial infection. |
| Human or seal? Who has the best underwater hearing? Posted: 24 May 2022 07:05 AM PDT We humans do better on land than under water -- also when it comes to our hearing. But now a new study shows that we actually have better underwater hearing than previously thought -- at certain frequencies we hear just as well as the seal. |
| Microbes can degrade the toughest PFAS Posted: 23 May 2022 01:28 PM PDT Engineers now report selective breakdown of a particularly stubborn class of PFAS called fluorinated carboxylic acids (FCAs) by common microorganisms. Under anaerobic conditions, a carbon-carbon double bond is crucial for the shattering the ultra-strong carbon-fluorine bond by microbial communities. The resulting products could be relayed to other microorganisms for defluorination under in aerobic conditions. |

Ground-dwellers, on the other hand, freak out during free-fall. The salamander's skydiving skills are likely a way to steer back to a tree it has fallen or jumped from to avoid terrestrial predators. |
| Noisy jackdaw birds reach 'consensus' before taking off Posted: 23 May 2022 08:55 AM PDT On cold, dark winter mornings, small black crows known as jackdaws can be heard calling loudly to one another from their winter roosting spots in the U.K. before taking off simultaneously right around sunrise. Now, researchers who've studied their daily activities in unprecedented detail report evidence that these groups of hundreds of individuals rely on a 'democratic' decision-making process to coordinate with one another and take to the skies all at once. |
| Scientists find sea corals are source of sought-after 'anti-cancer' compound Posted: 23 May 2022 08:55 AM PDT The bottom of the ocean is full of mysteries but scientists have recently uncovered one of its best-kept secrets.

The study, carried out on Drosophila melanogaster using electron microscopy equipment developed by the researchers themselves, represents a significant step towards a more precise analysis of the health risks of being exposed to these pollutants. |
| New measurements from Northern Sweden show less methane emissions than feared Posted: 23 May 2022 07:22 AM PDT It is widely understood that thawing permafrost can lead to significant amounts of methane being released. However, new research shows that in some areas, this release of methane could be a tenth of the amount predicted from a thaw. A crucial, yet an open question is how much precipitation the future will bring. |
| What happens when plants have stress reactions to touch Posted: 23 May 2022 07:22 AM PDT A 30-year-old genetic mystery has been solved. It has previously been established that touch can trigger stress reactions in plants. However, the molecular models for explaining this process have been quite spartan so far. Now researchers have found genetic keys that explain how plants respond so strongly to mechanical stimuli. Cracking this code could help lead to higher yields and improved stress resistance in crops in the future. |
