| Haptics device creates realistic virtual textures Posted: 21 May 2022 06:33 AM PDT Tactile sensation is an incredibly important part of how humans perceive their reality. Haptics or devices that can produce extremely specific vibrations that can mimic the sensation of touch are a way to bring that third sense to life. However, as far as haptics have come, humans are incredibly particular about whether or not something feels 'right,' and virtual textures don't always hit the mark. Now, researchers at the USC Viterbi School of Engineering have developed a new method for computers to achieve that true texture -- with the help of human beings. Called a preference-driven model, the framework uses our ability to distinguish between the details of certain textures as a tool in order to give these virtual counterparts a tune-up. |

| Organic farming or flower strips: Which is better for bees? Posted: 21 May 2022 06:33 AM PDT How effective environmental measures in agriculture are for biodiversity and wild bee populations depends on various factors and your perspective. This is shown by agroecologists. The research team found that when assessing the effectiveness of different measures, whether in the field (organic farming) or next to the field (flower strips in conventional farming), biodiversity benefits should be evaluated differently. Like-for-like comparisons of environmental measures could easily be misleading, according to the scientists. |

| PFAS chemicals do not last forever Posted: 20 May 2022 11:47 AM PDT Once dubbed 'forever chemicals,' per-and polyfluoroalkyl substances, or PFAS, might be in the market for a new nickname. Adding iodide to a water treatment reactor that uses ultraviolet (UV) light and sulfite destroys up to 90% of carbon-fluorine atoms in PFAS forever chemicals in just a few hours, reports a new study led by environmental engineers. The addition of iodide accelerates the speed of the reaction up to four times, saving energy and chemicals. |
| Haywire T cells attack protein in 'bad' cholesterol Posted: 20 May 2022 11:47 AM PDT Detecting these T cells may lead to diagnostics to better detect heart disease--and disease severity--through a blood sample. The knowledge also brings researchers closer to developing a vaccine that dampens this dangerous immune cell activity to prevent atherosclerosis. |
| Light pollution can disorient monarch butterflies Posted: 20 May 2022 11:46 AM PDT Biologists say nighttime light pollution can interfere with the remarkable navigational abilities of monarchs, which travel as far as Canada to Mexico and back during their multi-generational migration. Researchers found that butterflies roosting at night near artificial illumination such as a porch or streetlight can become disoriented the next day because the light interferes with their circadian rhythms. Artificial light can impede the molecular processes responsible for the butterfly's remarkable navigational ability and trigger the butterfly to take wing when it should be resting. |
| Posted: 20 May 2022 11:46 AM PDT Unlike fictional laser swords, real laser beams do not interact with each other when they cross -- unless the beams meet within a suitable material allowing for nonlinear light-matter interaction. In such a case, wave mixing can give rise to beams with changed colors and directions. |
