Scientists have developed a new plastic material that can be recycled repeatedly.

Microsoft is adding a real Linux kernel to Windows 10, and has a new Windows Terminal command-line app for developers.

These scores are a good deal lower than phones using the latest Snapdragon 855 processor, such as the Galaxy S10, as well as the Snapdragon 845 chipset in the Pixel 3 series. However, it surprisingly beat out the Google Pixel 2 and 2 XL, which scored 146,876 and 110,949 on AnTuTu, respectively.

There may be a few graphically-intensive games that could give the Pixel 3a and 3a XL pause, but so far, my experience has been pleasantly smooth.

Chrome 74 was released only a few days ago, which means v75 has moved up to the Beta Channel. This release doesn’t have any drastic changes, but it does continue to improve the dark theme, and there are some fancy new APIs that web apps can use.

Dark theme changes

An ancient neutron star collision occurred very, very close to our solar system — and we’re all the better for it.

Study authors say the results don’t mean consumers should stop using sunscreen, but noted that more research needs to be done.

Android Q introduces a bunch of new features, while putting protections in place to provide even more transparency and control over your data.

Harvesters scale tall cliffs to collect this rare honey from Himalayan giant honeybees.

Redox flow batteries are attractive for large-scale energy storage due to a combination of high theoretical efficiencies and decoupled power and energy storage capacities. Efforts to significantly increase energy densities by using nonaqueous electrolytes have been impeded by separators with low selectivities. Here, we report nanoporous separators based on aramid nanofibres, which are assembled using a scalable, low cost, spin-assisted layer-by-layer technique. The multilayer structure yields 5 ± 0.5 nm pores, enabling nanofiltration with high selectivity. Further, surface modifications using polyelectrolytes result in enhanced performance. In vanadium acetylacetonate/acetonitrile-based electrolytes, the coated separator exhibits permeabilities an order of magnitude lower and ionic conductivities five times higher than those of a commercial separator. In addition, the coated separators exhibit exceptional stability, showing minimal degradation after more than 100 h of cycling. The low permeability translates into high coulombic efficiency in flow cell charge/discharge experiments performed at cycle times relevant for large-scale applications (5 h).
