| A recent reversal in the response of western Greenland’s ice caps to climate change Posted: 09 Sep 2021 01:22 PM PDT Greenland may be best known for its enormous continental scale ice sheet that soars up to 3,000 meters above sea level, whose rapid melting is a leading contributor to global sea level rise. But surrounding this massive ice sheet, which covers 79% of the world's largest island, is Greenland's rugged coastline dotted with ice capped mountainous peaks. These peripheral glaciers and ice caps are now also undergoing severe melting due to anthropogenic (human-caused) warming. However, climate warming and the loss of these ice caps may not have always gone hand-in-hand. |

| Potential indicator for obesity risk detected during sleep Posted: 09 Sep 2021 09:40 AM PDT Researchers have shown that people with inflexible metabolisms burn less fat at night than those with flexible metabolism. The team measured the respiratory quotient throughout the night and found that despite equal ages, BMIs, and amount of fat, people with inflexible metabolisms burned more carbohydrates and less fat than did people with flexible metabolisms. The higher sleep-time quotient could be a previously unknown indicator for the risk of future metabolic disease. |

| 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.
