| The physics behind a tardigrade's lumbering gait Posted: 27 Aug 2021 03:41 PM PDT Animals as small and soft as tardigrades seldom have legs and almost never bother walking. But a new study finds that water bears propel themselves through sediment and soil on eight stubby legs, in a manner resembling that of insects 500,000 times their size. |
| Common pesticide may contribute to global obesity crisis Posted: 27 Aug 2021 03:41 PM PDT Researchers discovered that chlorpyrifos, which is banned for use on foods in Canada but widely sprayed on fruits and vegetables in many other parts of the world, slows down the burning of calories in the brown adipose tissue of mice. Reducing this burning of calories, a process known as diet-induced thermogenesis, causes the body to store these extra calories, promoting obesity. Scientists made the discovery after studying 34 commonly used pesticides and herbicides in brown fat cells and testing the effects of chlorpyrifos in mice fed high calorie diets. |
| Global sand and gravel extraction conflicts with half of UN Sustainable Development Goals Posted: 27 Aug 2021 10:37 AM PDT Sand and gravel are the most mined materials in the world, with between 32 and 50 billion tons extracted globally each year. They are being extracted faster than they can be replaced. But according to a new study, the human and environmental costs of this extraction on lower and middle-income countries have been largely overlooked. |
| Rare barley mutation with potential Posted: 27 Aug 2021 09:15 AM PDT The importance of the root system for agricultural yields is often underestimated. Whether roots can access water and nutrients effectively also determines the resilience of important crops to drought and climate change. Researchers have discovered and described a mutant in barley: Its roots grow downwards much more sharply than usual. This discovery potentially provides a starting point for breeding more drought-resistant varieties. |
| Carbon neutrality – a new policy brief for municipalities world wide Posted: 27 Aug 2021 09:15 AM PDT How to design efficient demo areas for urban carbon sequestration? In the latest policy brief research groups focus on the main principles of urban demonstration areas using biochars for carbon sequestration. |
| Posted: 26 Aug 2021 02:01 PM PDT Updating the laws, the researchers say, will allow the true value of public resources to be revealed in an environmental market. It will give different groups equal footing in auctions, and create a more stable, actionable path toward conservation, to the benefit of both industry and the environment. |
| Heat stress in dairy cows damages health of calves Posted: 26 Aug 2021 09:21 AM PDT As scientists continue to explore the wide-ranging effects of heat stress on the health of dairy cattle, a new study adds to the growing understanding of the negative influences of heat stress, not just throughout the lifespan but across generations. |
