| Machine learning platform mines nature for new drugs Posted: 02 Jun 2021 12:34 PM PDT Researchers have developed a new process using machine learning algorithms to match the signals of a microbe's metabolites with its genomic signals and identify which likely correspond to a natural product. Knowing that, researchers are better equipped to isolate the natural product to begin developing it for a possible drug and possibly reinvigorate the search for natural product drugs. |
| Dead zones formed repeatedly in North Pacific during warm climates Posted: 02 Jun 2021 12:34 PM PDT An analysis of sediment cores from the Bering Sea has revealed a recurring relationship between warmer climates and abrupt episodes of low-oxygen 'dead zones' in the subarctic North Pacific Ocean over the past 1.2 million years. The findings provide crucial information for understanding the causes of low oxygen or 'hypoxia' in the North Pacific and for predicting the occurrence of hypoxic conditions in the future. |
| Major advance in fabrication of low-cost solar cells also locks up greenhouse gases Posted: 02 Jun 2021 12:33 PM PDT Engineers have created a means of vastly increasing the speed and efficiency of a key doping process for perovskite solar cells, one that also sequesters CO2. |
| The best strawberries to grow in hot locations Posted: 02 Jun 2021 10:04 AM PDT It's strawberry season in many parts of the U.S, and supermarkets are teeming with these fresh heart-shaped treats. Although the bright red, juicy fruit can grow almost anywhere with lots of sunlight, production in some hot, dry regions is a challenge. Now, researchers have identified five cultivars that are best suited for this climate, which could help farmers and consumers get the most fragrant, sweetest berries. |
| Salps fertilize the Southern Ocean more effectively than krill Posted: 02 Jun 2021 10:03 AM PDT Experts have experimentally measured the release of iron from the fecal pellets of krill and salps under natural conditions and tested its bioavailability using a natural community of microalgae in the Southern Ocean. |
| Plastic waste in the sea mainly drifts near the coast Posted: 02 Jun 2021 10:02 AM PDT A study provides new insights into the pollution of the world's oceans with plastic waste. The modelling shows that most of the plastic does not end up in the open ocean, but beaches or drifts in the water near the coast. |
| A 'jolt' for ocean carbon sequestration Posted: 02 Jun 2021 07:16 AM PDT Global oceans absorb about 25 percent of the carbon dioxide released into the atmosphere when fossil fuels are burned. Electricity-eating bacteria known as photoferrotrophs could provide a boost to this essential process, according to new research. |
| Newly identified atmospheric circulation enhances heatwaves and wildfires around the Arctic Posted: 02 Jun 2021 06:14 AM PDT Scientists have uncovered a summertime climate pattern in and around the Arctic that could drive co-occurrences of European heatwaves and large-scale wildfires with air pollution over Siberia and subpolar North America. |
| Researchers explore ways to detect 'deep fakes' in geography Posted: 02 Jun 2021 06:14 AM PDT It may only be a matter of time until the growing problem of 'deep fakes' converges with geographical information science (GIS). A research team are doing what they can to get ahead of the problem. |
| Mapping intermittent methane emissions across the Permian Basin Posted: 02 Jun 2021 06:14 AM PDT The Permian Basin, located in western Texas and southeastern New Mexico, is the largest oil- and gas-producing region in the U.S. The oilfield operations emit methane, but quantifying the greenhouse gas is difficult because of the large area and the fact that many sources are intermittent emitters. Now, researchers have conducted an extensive airborne campaign with imaging spectrometers and identified large methane sources across this area. |
| Atmospheric metal layers appear with surprising regularity Posted: 02 Jun 2021 06:14 AM PDT Twice a day, at dusk and just before dawn, a faint layer of sodium and other metals begins sinking down through the atmosphere, about 90 miles high above the city of Boulder, Colorado. The movement was captured by one of the world's most sensitive 'lidar' instruments and the regularly appearing layers promise to help researchers understand better how earth's atmosphere interacts with space, even potentially how those interactions help support life. |
| Synthetic SPECIES developed for use as a confinable gene drive Posted: 02 Jun 2021 06:14 AM PDT Scientists have developed a gene drive with a built-in genetic barrier that is designed to keep the drive under control. The researchers engineered synthetic fly species that, upon release in sufficient numbers, act as gene drives that can spread locally and be reversed if desired. |
| Researchers learn how swimming ducks balance water pressure in their feathers while diving Posted: 02 Jun 2021 06:13 AM PDT A team has discovered the method ducks use to suspend water in their feathers while diving, allowing them to shake it out when surfacing. The discovery opens the door for applications in marine technology. |
