Pushing the Boundaries of Wireless Power<\/h2>\n\n\n\n

Founded in 2008 by physicist and technologist Hatem Zeine, Ossia is challenging people\u2019s core assumptions about what is possible with wireless power. https:\/\/www.ossia.com\/ Headquartered in Redmond, WA, Ossia\u2019s Cota technology redefines wireless power by safely delivering targeted energy to devices at a distance. Ossia\u2019s patented RF smart antenna technology automatically keeps multiple devices charged without any user intervention, enabling an efficient and truly wire-free, powered-up world that is always on and always connected.<\/p>\n\n\n\n

The Hole in Earth’s Ozone Layer Is Healing, First-of-Its-Kind Study Shows By Calla Cofield<\/a> First Published 3 years ago https:\/\/www.space.com\/39315-nasa-satellite-shows-healing-ozone-hole.html<\/p>\n\n\n\n

Is the Ozone Layer Finally Healing Itself? BY John P. Rafferty<\/a> Some two years later, scientists got sufficient data to confidently reveal proof that the ozone layer was indeed on a path to recovery.<\/strong> The 2016 study, which tracked the evolution of the size of the ozone hole over Antarctica, observed that stratospheric ozone concentrations were continuing to increase and that the size of the Antarctic ozone hole had declined by half the size of the continental U.S. between 2000 and 2015. The authors of the study also noted that they expected the ozone layer to fully heal sometime between 2040 and 2070. https:\/\/www.britannica.com\/story\/is-the-ozone-layer-finally-healing-itself<\/p>\n\n\n\n

As the world\u2019s waste mounts, a Shell pilot plant will turn rubbish \u2013 including food, cardboard, plastics and paper \u2013 into petrol or diesel that can power cars.<\/p>\n\n\n\n

At the end of the film Back to the Future something amazing happens. Doc Brown appears in his time-travelling DeLorean car and, as he talks excitedly to Marty McFly, he starts pulling things out of a bin.<\/p>\n\n\n\n

\u201cI need fuel,\u201d he says, before dropping a banana skin and other bits into a hopper on the back of the car. <\/p>\n\n\n\n

There is no time machine, but in Bangalore, India, Shell is building a pilot plant that will turn waste \u2013 even discarded household junk \u2013 into petrol or diesel that can power cars.<\/p>\n\n\n\n

\u201cThe quest to turn rubbish into energy is this century\u2019s alchemy,\u201d says Dr Alan Del Paggio, vice president of CRI Catalyst Company, the Shell business which licenses the technology worldwide. \u201cOnly, it\u2019s not magic; it\u2019s simple chemistry.\u201d<\/p>\n\n\n\n

Biocompatible near-infrared quantum dots delivered to the skin by microneedle patches record vaccination<\/h2>\n\n\n\n

Kevin J. McHugh, Lihong Jing, […], and Ana Jaklenec Additional article information https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC7532118\/#__ffn_sectitle Therefore, we aimed to develop a platform that is robust, inexpensive, and easy-to-use to overcome the primary obstacles to implementation in the developing world. We hypothesized that information, such as vaccination history, could be encoded invisibly in the skin by applying a distinct pattern of near-infrared (NIR) fluorescent microparticles using a microneedle patch. By providing all of the requisite information on the patients themselves, and delivering microparticles in the same microneedles as the vaccine, this platform offers several key advantages compared to traditional paper or electronic medical record[s] Funding<\/strong>: This work was funded by the Bill & Melinda Gates Foundation grant OPP 1150646. https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC7532118\/<\/p>\n\n\n\n

Moreover, four bufadienolides (4<\/strong>\u20137<\/strong>) and eight other compounds were also characterized from the title plant. The isolated compounds (1<\/strong>\u20137<\/strong>) were evaluated for their cytotoxicity toward MCF-7, NCI-H460, and SF-268 tumor cell lines. Among them, compounds 4<\/strong> and 6<\/strong> displayed significant cytotoxicity toward MCF-7 and NCI-H460 tumor cell lines at the tested concentration. In addition, the biosynthetic pathway of these \u03b1-pyrone ring-opening derivatives was also proposed. https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0040402008001476<\/p>\n\n\n\n
