| Environmentally conscious consumers more likely to buy chicken raised on insects or algae Posted: 22 Mar 2022 09:25 AM PDT Eating chicken raised on a diet of bugs or algae may sound downright unappetizing to some, but there are ways to make the idea more palatable to at least one type of food shopper. Consumers who are environmentally aware will likely warm up to the idea of using alternative proteins like insect meal in poultry feed if they're given enough information about the health and environmental benefits, a new study shows. |
| Striking lane-like patterns found in bacteria populations Posted: 22 Mar 2022 08:13 AM PDT Researchers have found that competing strains of Escherichia coli bacteria form distinctive lane-like patterns as their populations grow. |
| Posted: 22 Mar 2022 08:13 AM PDT Using multiple high-resolution satellite datasets, researchers found that tropical carbon loss has doubled over the past two decades due to excessive forest removal in the tropics. The tropics are an important ecosystem as they store massive amounts of carbon in their woody vegetation and soil -- but they have suffered from extensive forest clearance since 2001. The researchers analyzed the gross forest carbon loss associated with forest removal in the tropics during the 21st century. |

| Cryo-EM reveals how '911' molecule helps fix damaged DNA Posted: 21 Mar 2022 10:21 AM PDT When something goes wrong during DNA replication, cells call their own version of 911 to pause the process and fix the problem -- a failsafe that is critical to maintaining health and staving off disease. Now, scientists have for the first time revealed how a key piece of this repair process -- appropriately called the 911 DNA checkpoint clamp -- is recruited to the site of DNA damage. The findings illuminate new insights into the way cells ensure genetic instructions are properly passed from one generation of cells to the next. |
| How the Chagas pathogen changes the intestinal microbiota of predatory bugs Posted: 21 Mar 2022 10:21 AM PDT In Central and South America, predatory blood-sucking bugs transmit the causative agent of the widely prevalent Chagas disease. As the disease can induce severe symptoms and to date there is no vaccine against the Trypanosoma parasites, the main approach at present is to control the bug using insecticides. A research team has now studied how trypanosomes change the bug's intestinal microbiota. The long-term goal: to change the bacterial community in the predatory bug's intestine in such a way that it can defend itself against the trypanosomes. |
| The shape of bacteria can make it a more effective, and useful predator Posted: 21 Mar 2022 08:58 AM PDT Scientists have found that a predatory bacterium, capable of invading and consuming harmful bugs such as E.coli and Salmonella, can sculpt its own shape to fit inside its prey. Scientists have shown that the curved (boomerang-like) shape of the bacterium, called Bdellovibrio bacteriovorus, is an important feature that affects its lifestyle, enabling it to efficiently invade, grow and live inside other bacteria. |
