| Colorectal cancer tumors both helped and hindered by T cells Posted: 22 Jul 2022 03:48 PM PDT Colorectal tumors are swarming with white blood cells, but whether these cells help or hinder the cancer is hotly debated. While some studies have shown that white blood cells heroically restrict tumor growth and combat colorectal cancer, equally compelling evidence casts the white blood cells as malignant co-conspirators -- bolstering the tumor and helping it spread. |
| Genetic defect leads to motor disorders in flies Posted: 22 Jul 2022 03:48 PM PDT Researchers have discovered a protein whose defect causes motor disorders in flies. The protein had also previously been found in human patients with Parkinson's disease. So far, however, it was not known what function it has in the cell. The study now provides an answer to this question. |
| How the intestine replaces and repairs itself Posted: 22 Jul 2022 03:48 PM PDT A new study suggests that stem cells are able to integrate cues from their surroundings and coordinate their behavior across tissue through networks of vasculature in their close vicinity. |
| Ant colonies behave like neural networks when making decisions Posted: 22 Jul 2022 03:48 PM PDT Colonies decide to flee rising temperatures in much the same way that neural computations give rise to decisions. |
| New method can improve explosion detection Posted: 22 Jul 2022 03:48 PM PDT Computers can be trained to better detect distant nuclear detonations, chemical blasts and volcano eruptions by learning from artificial explosion signals, according to a new method. |
| The bigger the temperature change, the larger the extinction event Posted: 22 Jul 2022 09:32 AM PDT Scientists have unearthed evidence pointing to a strong relationship between the magnitude of mass extinctions and global temperature changes in geologic times. This interesting correlation reveals a more optimistic outlook on future extinction events. |
| Scientists expand entomological research using genome editing Posted: 22 Jul 2022 09:32 AM PDT Researchers have developed a work-flow method, called Fanflow4Insects, that annotates gene functions in insects. In functional annotation, scientists collect information about a gene's biological identity. The team's new method uses transcribed sequence information as well as genome and protein sequence databases. With Fanflow4Insects, the team has annotated the functional information of the Japanese stick insect and the silkworm, including gene expression as well as sequence analysis. The functional annotation information that their workflow provides will greatly expand the possibilities of entomological research using genome editing. |
| Porous crystals bind fluorine-containing greenhouse gases Posted: 22 Jul 2022 09:32 AM PDT Fluorine-containing gases -- including so-called per- or polyfluorinated hydrocarbons, or PFCs -- have a significant share in global warming. Researchers recently developed new crystalline materials that can selectively adsorb the molecules of such carbon-fluorine bonds. They hope that these porous crystals may be useful for targeted binding and recovery of PFCs. |
| Wildfire-smoke observations fill gap in estimating soot's role in climate change Posted: 21 Jul 2022 05:48 PM PDT New research refining the amount of sunlight absorbed by black carbon in smoke from wildfires will help clear up a long-time weak spot in earth system models, enabling more accurate forecasting of global climate change. |
| Women urged to eat potassium-rich foods to improve their heart health Posted: 21 Jul 2022 05:48 PM PDT Women who eat bananas, avocados and salmon could reduce the negative effects of salt in the diet, according to a new study. The study found that potassium-rich diets were associated with lower blood pressure, particularly in women with high salt intake. |
| How 'shark week' could inspire love for ocean predators Posted: 21 Jul 2022 12:55 PM PDT Findings from a new study indicate more positive YouTube videos could be a useful tool for shark conservation. |
| Tomatoes, but not farm workers, gardeners, safe from soil lead Posted: 21 Jul 2022 12:55 PM PDT Scientists don't know much about how vegetables and other crops take up and accumulate lead in real-world settings, but new research in Chicago backyard gardens shows tomatoes are likely safe to eat, even when grown in highly lead-contaminated soils. |
| Resistance to cassava mosaic disease explained Posted: 21 Jul 2022 10:20 AM PDT Researchers have identified the gene responsible for resistance in certain cassava cultivars against the devastating cassava mosaic disease. This is an important step for breeding virus-resistant cassava varieties. |
| Natural food more mouth-watering to children than processed fare Posted: 21 Jul 2022 10:20 AM PDT Children are more likely to prefer foods they believe to be natural to lab-grown options, rating them higher for tastiness, safety and desirability, a study shows. Researchers say the tendency in adults to prefer natural food is well documented. However, the latest findings found this food preference exists in early and middle childhood as well. |
| Moths enlist additional troops in an evolutionary arms race Posted: 21 Jul 2022 10:20 AM PDT A new study shows that ultrasound-producing moths are far more widespread than previously thought, adding three newly discovered sound-producing organs, eight new subfamilies and potentially thousands of species to the roster. |
| Why some flu viruses cause more severe infections Posted: 21 Jul 2022 10:20 AM PDT Research uses computational modeling to try to understand the body's immune response to avian flu. His latest work finds that the levels of interferon may be responsible for its more severe presentation -- and may also be the key to treating it. |
| Posted: 21 Jul 2022 10:20 AM PDT Climate change is causing a mass extinction the likes of which has not been seen in recorded history. For birds, this biodiversity loss has implications beyond just species loss. Researchers use statistical modelling to predict that extinction will decrease morphological diversity among remaining birds at a rate greater than species loss alone. The team's results reveal which birds we are at risk of losing and which regions are most susceptible to homogenization. |
