| Food science meets cell science in bid to explain inner workings of membrane-free cell compartments Posted: 09 Sep 2021 11:12 AM PDT Researchers report that food science principles have helped them determine how unusual droplets within cells stay organized and avoid dissolving into the rest of the cell's gelatinous interior. |
| Marine Protected Area status can boost fish populations by almost 400% Posted: 09 Sep 2021 09:39 AM PDT Researchers have been monitoring the impact of the Lyme Bay Marine Protected Area (MPA). It was designated in 2008, and researchers now found there are 370% more fish within the MPA than in similar areas outside it where bottom-towed fishing is still permitted. |
| Scientists discover that taste cells can control a whole animal’s foraging strategy Posted: 09 Sep 2021 09:39 AM PDT Neuroscientists have developed a computer model to explain how a nematode worm searches for food, revealing that single brain cells can both sense the environment and control a whole animal's foraging strategy. The study involved the microscopic nematode species, Caenorhabditis elegans. |
| Transforming marine biodiversity discovery and monitoring Posted: 09 Sep 2021 09:39 AM PDT A new system for sampling fragments of DNA from marine organisms drifting in the ocean is set to create new opportunities for research on biodiversity and ways of supporting conservation activities. The results showed the ferry-collected samples had traces of DNA from all parts of the vertebrate ecosystem, ranging from small prey fish at the base of the food chain, such as anchovies and sardines, through small and larger predatory fish such as tuna and swordfish, all the way to dolphins, and ocean giants including fin and sperm whales. |
| New embryo identification IVF method set to boost cow milk and meat production Posted: 08 Sep 2021 03:06 PM PDT New research has established a method of significantly improving in-vitro fertilization (IVF) in cattle. |
| Forest fires linked to tens of thousands of avoidable deaths Posted: 08 Sep 2021 03:05 PM PDT Setting fire to forest and agricultural land in Southeast Asia to prepare it for cultivation or grazing causes air pollution that is contributing to an estimated 59,000 premature deaths a year, according to a new study. |
| Hand pollination of crops is of major importance Posted: 08 Sep 2021 03:04 PM PDT Pollinators -- such as bees, butterflies and birds -- are essential for agricultural production. However, natural pollination can also fail or be insufficient, which can lead to lower yields and poorer quality. This means alternative solutions are needed. Hand pollination, in which pollen is applied manually or mechanically to the flower, can supplement or replace pollination by animals. Researchers now present the first systematic review of hand pollination of food crops. They show that hand pollination is used worldwide on 20 crops, including economically important plants such as apple, oil palm and cocoa. |
| ‘Anti-rust’ coating for plants protects against disease with cellulose nanofiber Posted: 08 Sep 2021 03:04 PM PDT Researchers have found that coating soybean plant leaves with cellulose nanofiber (CNF) gives protection against an aggressive fungal disease. The CNF coating changed leaf surfaces from water repellent to water absorbent, and suppressed pathogen gene expression associated with infection mechanisms, offering resistance to the destructive Asian rust disease. This is the first study to examine CNF application for controlling plant diseases, and it offers a sustainable alternative to managing plant disease. |
| Transatlantic slave trade introduced novel pathogenic viruses in the Americas Posted: 07 Sep 2021 08:07 AM PDT Cutting-edge genetic techniques are shedding new light on how European colonists and their enslavement of African people may have contributed to epidemics among Indigenous communities in North America. |
