| Global BECCS potential is largely constrained by sustainable irrigation Posted: 05 Jul 2021 08:39 AM PDT Bioenergy with Carbon Capture and Storage (BECCS), a negative emission technology, has been considered inevitable to achieve the 2°C or 1.5°C climate goal. Although numerous studies have been conducted, the effect of irrigation remains largely unexplored when taking water use sustainability into consideration. A new study finds that although unlimited irrigation could increase the global BECCS potential by 60-71% by the end of this century, sustainably constrained irrigation would increase it only 5-6%. |
| Psychedelic spurs growth of neural connections lost in depression Posted: 05 Jul 2021 08:39 AM PDT In a new study, researchers show that a single dose of psilocybin given to mice prompted an immediate and long-lasting increase in connections between neurons. The findings are published July 5 in the journal Neuron. |
| Astronomers discover an oversized black hole population in the star cluster Palomar 5 Posted: 05 Jul 2021 08:39 AM PDT Palomar 5 is a unique star cluster. In a new paper, astrophysicists show that distinguishing features of Palomar 5 are likely the result of an oversized black hole population of more than 100 of them in the center of the cluster. |
| Belowground microbial solutions to aboveground plant problems Posted: 05 Jul 2021 08:39 AM PDT Researchers have discovered that signaling occurring from the response of plant leaves to light, and plant roots to microbes, is integrated along a microbiota-root-shoot axis to boost plant growth when light conditions are suboptimal. |
| More filling? Tastes great? How flies, and maybe people, choose their food Posted: 05 Jul 2021 06:47 AM PDT Flies have discriminating taste. Like a gourmet perusing a menu, they spend much of their time seeking sweet nutritious calories and avoiding bitter, potentially toxic food. But what happens in their brains when they make these food choices? Researchers discovered an interesting way to find out. They tricked them. |
| Hunting and hidden deaths led to 30% reduction in WI wolf population Posted: 05 Jul 2021 06:47 AM PDT About 100 additional wolves died over the winter in Wisconsin as a result of the delisting of grey wolves under the Endangered Species Act, alongside the 218 wolves killed by licensed hunters during Wisconsin's first public wolf hunt, according to new research. A majority of these additional, uncounted deaths are due to cryptic poaching, where poachers hide evidence of illegal killings. |
| Breakthrough in tissue engineering as 'shape memory' supports tissue growth Posted: 05 Jul 2021 06:47 AM PDT New research has demonstrated the viability of 3D-printed tissue scaffolds that harmlessly degrade while promoting tissue regeneration following implantation. |
| Being clean and hygienic need not impair childhood immunity Posted: 05 Jul 2021 06:47 AM PDT The theory that modern society is too clean, leading to defective immune systems in children, should be swept under the rug, according to a new study. |
| Researchers find potential path to a broadly protective COVID-19 vaccine using T cells Posted: 02 Jul 2021 12:43 PM PDT Using a method developed for HIV, researchers have identified stable T cell vaccine targets in SARS-CoV-2. These stable targets, known as highly networked epitopes, are highly likely to be stable in different variants of the virus. The results provide a path forward for a broadly protective COVID-19 T cell vaccine. |
| Lottery-based incentives do not increase COVID-19 vaccination rates, study finds Posted: 02 Jul 2021 12:43 PM PDT Researchers found that Ohio's 'Vax-a-Million' lottery-based incentive system, intended to increase COVID-19 vaccination rates, was not associated with an increase in COVD-19 vaccinations. |
| Cancer cells eat themselves to survive Posted: 02 Jul 2021 12:39 PM PDT New research shows that in order to survive life threatening injuries, cancer cells use a technique in which they eat parts of the membrane surrounding them. |
| Color and flavor: Pigments play a role in creating tasty tomatoes Posted: 02 Jul 2021 08:46 AM PDT Researchers have found that pigments controlling the color of tomatoes also play a role in determining their flavor. By analyzing the pigment profiles of 157 different tomato varieties, the team showed that fruit with high chlorophyll levels had a higher sugar content, and that the carotenoid, prolycopene, is associated with an abundance of aroma compounds. Understanding how growing conditions influence pigment profiles could improve the flavor of tomatoes. |
