| Posted: 12 Jul 2021 09:22 AM PDT The sharp eyes of an eagle, the extraordinary hearing of an owl - to successfully find food, the eyes and ears of birds have adapted optimally to their living conditions. Until now, the sense of smell has played a rather subordinate role. When meadows are freshly mowed, storks often appear there to search for snails and frogs. Researchers have now studied the birds' behavior and discovered that the storks are attracted by the smell of the mown grass. Only storks that were downwind and could thus perceive the smell reacted to the mowing. The scientists also sprayed a meadow with a spray of green leaf scents released during mowing. Storks appeared here as well. This shows that white storks use their sense of smell to forage and suggests that the sense of smell may also play a greater role in other birds than previously thought. |

This knack for understanding human gestures may seem unremarkable, but it's a complex cognitive ability that is rare in the animal kingdom. New research comparing dog puppies to human-reared wolf pups offers some clues to how dogs' unusual people-reading skills came to be. |

| Sensing 'junk' RNA after chemotherapy enhances blood regeneration Posted: 12 Jul 2021 09:21 AM PDT Scientists reveal that during hematopoietic regeneration, RNA expressed from a part of the genome considered 'junk DNA' is used by hematopoietic stem cells to get activated and proliferate. The study shows that these so-called transposable elements make RNA after chemotherapy and activate an immune receptor which induces inflammatory signals enhancing hematopoietic stem cell cycling and thus participating in the regeneration of the hematopoietic system. |
