| These geckos crash-land on rainforest trees but don't fall, thanks to their tails Posted: 02 Sep 2021 09:51 AM PDT Many arboreal lizards leap and glide from tree to tree, but what if they can't glide to a gentle, four-point landing? Researchers documented many such leaps of the common house gecko, and found that they often hit trees headfirst and rebounded violently. Their recovery strategy -- grab on with the back feet and leverage their tail to prevent falling. The team created a soft robot with reactive tail that could replicate this previously unknown fall-arresting behavior. |
| Highly dynamic sex chromosomes in cichlid fishes Posted: 02 Sep 2021 09:49 AM PDT The cichlids of Lake Tanganyika in Africa are highly diverse -- including with regard to sex chromosomes. These have changed extremely frequently in the course of the evolution of these fish and, depending on the species, can be of the type XY or ZW. |
| Less salt, more protein: Researchers address dairy processing's environmental, sustainability issues Posted: 02 Sep 2021 09:49 AM PDT Researchers say the high salt content of whey -- the watery part of milk left behind after cheesemaking -- helps make it one of the most polluting byproducts in the food processing industry. In a new study, chemists demonstrate the first electrochemical redox desalination process used in the food industry, removing and recycling up to 99% of excess salt from whey while simultaneously refining more than 98% of whey's valuable protein content. |
| Painful fractures: Large eggs push small hens to the breaking point, study finds Posted: 02 Sep 2021 09:49 AM PDT The majority of laying hens in Denmark suffer from keel bone fractures, a new study reveals. The fractures appear to be the result of disproportionately large eggs, which push the hen's body to the breaking point. |
| Going up: Birds and mammals evolve faster if their home is rising Posted: 02 Sep 2021 09:49 AM PDT The rise and fall of Earth's land surface over the last three million years shaped the evolution of birds and mammals, a new study has found, with new species evolving at higher rates where the land has risen most. |
| TRACS set the stage in flatworm regeneration Posted: 02 Sep 2021 09:49 AM PDT A new study show that whole-body regeneration involves transcriptional changes in cells from all three germ layers (muscle, epidermis, and intestine) of the body, and that tissue from areas distant from, as well as nearby to the site of injury, contribute to the process of regeneration. |
| Indigenous and local communities key to successful nature conservation Posted: 01 Sep 2021 04:14 PM PDT New research finds that Indigenous Peoples and local communities provide the best long-term outcomes for conservation. The research team studied the outcomes of 169 conservation projects around the world -- primarily across Africa, Asia and Latin America. |
| Patterns of income and urbanization impact mammal biodiversity in the concrete jungle Posted: 01 Sep 2021 09:40 AM PDT New research suggests that while there is an association between income and diversity of medium to large mammals, another factor is stronger: 'urban intensity', or the degree to which wild lands have been converted to densely-populated, paved-over grey cities. |
