| Toxin-producing yeast strains in gut fuel IBD Posted: 16 Mar 2022 11:58 AM PDT Individual Candida albicans yeast strains in the human gut are as different from each other as the humans that carry them, and some C. albicans strains may damage the gut of patients with inflammatory bowel disease (IBD), according to a new study. The findings suggest a possible way to tailor treatments to individual patients in the future. |
| Effects of ancient carbon releases suggest possible scenarios for future climate Posted: 16 Mar 2022 11:57 AM PDT A massive release of greenhouse gases, likely triggered by volcanic activity, caused a period of extreme global warming known as the Paleocene-Eocene Thermal Maximum (PETM) about 56 million years ago. A new study now confirms that the PETM was preceded by a smaller episode of warming and ocean acidification caused by a shorter burst of carbon emissions. The short-lived precursor event represents what might happen if current emissions can be shut down quickly, while the much more extreme global warming of the PETM shows the consequences of continuing to release carbon into the atmosphere at the current rate. |
| BirdBot is energy-efficient thanks to nature as a model Posted: 16 Mar 2022 11:57 AM PDT A team of scientists has constructed a robot leg that, like its natural model, is very energy efficient. BirdBot benefits from a foot-leg coupling through a network of muscles and tendons that extends across multiple joints. In this way, BirdBot needs fewer motors than previous legged robots and could, theoretically, scale to large size. |
| U.S. fires four times larger, three times more frequent since 2000 Posted: 16 Mar 2022 11:57 AM PDT Fires have gotten larger, more frequent and more widespread across the United States since 2000, according to a new article. The research shows that large fires have not only become more common, they are also spreading into new areas, impacting land that previously did not burn. |
| Posted: 16 Mar 2022 10:27 AM PDT In what they call surprise findings, scientists report that -- unlike fruit flies -- mosquitoes' odor sensing nerve cells shut down when those cells are forced to produce odor-related proteins, or receptors, on the surface of the cell. This 'expression' process apparently makes the bugs able to ignore common insect repellents. |
| Discovery uncovers a new leaf for Redwoods Posted: 16 Mar 2022 10:27 AM PDT Redwood trees have two types of leaves, one to make food and the other to absorb water, found a new study. It's the first study to estimate whole-crown water absorption in a large, mature tree. The findings can help scientists monitor redwoods' adaptability amid a changing climate and deepens our understanding of the resilience of these massive trees. |
| Posted: 16 Mar 2022 10:27 AM PDT Researchers have found a way to improve the ability of catalysts made from metal-metal oxides to convert non-edible plants, such as wood, grass and corn stover into renewable fuels, chemicals and plastics. Metal oxide catalysts are central to reactions for upgrading petrochemicals, fine chemicals, pharmaceuticals and biomass. |
| Cheaper, more efficient ways to capture carbon Posted: 16 Mar 2022 10:27 AM PDT Researchers have developed a new tool that could lead to more efficient and cheaper technologies for capturing heat-trapping gases from the atmosphere and converting them into beneficial substances, like fuel or building materials. |
| Burst of rapid cell motion in 3D tumor model Posted: 16 Mar 2022 10:26 AM PDT Biological processes such as wound healing and cancer cell invasion rely on the collective and coordinated motion of living cells. A little understood aspect that influences these processes is the pressure differences within and between different parts of the body. Researchers designed model tumor systems using cervical cancer cells in collagen matrices to investigate whether pressure differences can push cancer cells into their surroundings. Upon embedding the model tumors into a soft matrix, an increased pressure led to a sudden burst of rapid and coordinated cellular motion that sprayed outwards from the tumor. |
| Pivotal technique harnesses cutting-edge AI capabilities to model and map the natural environment Posted: 16 Mar 2022 10:26 AM PDT Scientists have developed a pioneering new technique that harnesses the cutting-edge capabilities of AI to model and map the natural environment in intricate detail. |
| Nuclear reactor power levels can be monitored using seismic and acoustic data Posted: 16 Mar 2022 08:50 AM PDT Seismic and acoustic data recorded 50 meters away from a research nuclear reactor could predict whether the reactor was in an on or off state with 98% accuracy, according to a new study. |
| Novel 'Trojan horse' drug delivery system uses protein-based microdroplets Posted: 16 Mar 2022 06:17 AM PDT Scientists have developed a novel method of delivering drugs into human cells using large biological molecules, by first encasing them in a protein-based microdroplet. This discovery promises to be faster, safer, more effective, and better suited for gene therapy, cancer treatment, and vaccine delivery. |
