A Mongolian couple died from the bubonic plague after eating raw marmot meat, sparking a quarantine that trapped tourists for days, officials said Monday.

According to AFP, the couple died May 1 in a remote area of the country’s Bayan-Ölgii province, which borders China and Russia.

A six-day quarantine of 118 people who had come in contact with the couple, including locals and a number of foreign tourists, had been lifted as of Tuesday, Ariuntuya Ochirpurev, a World Health Organization official, told the BBC.

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

Chrome 75 includes a few changes to the dark theme that first arrived in Chrome 74, though you still have to activate the #enable-android-night-mode flag to try it out. The settings menu for it has been changed from ‘Dark mode’ to ‘Themes,’ and you can now force light mode to be on at all times (even when the system itself is in dark mode).

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).
