Microsoft has fixed yet another problem in some versions of Windows 10, a bug that makes the taskbar and desktop temporarily vanish or causes the system to ignore you. From a report: According to Redmond, users “might experience an error in which the desktop or taskbar might momentarily disappear, or your device might become unresponsive.” The issue affects PCs running Windows 10 versions 22H2, 21H2, 21H1, and 20H2, the company wrote on its Windows Health Dashboard. Microsoft didn’t outline the exact cause but notes it was related to the KB5016688 220820_03051 cumulative update and later.

The software giant is using its Known Issue Rollback (KIR) feature — which enables IT administrators to roll back the unwanted changes of an update — to resolve the problem, adding that it could take up to 24 hours for the fix to reach non-managed business systems and consumer devices. Restarting the device may accelerate the timeframe. Organizations that use enterprise-managed devices can install and configure a special Group Policy by going to “Computer Configuration” and then “Administrative Templates” and “Group Policy name.” If the resolution doesn’t work, users can try restarting the Windows device, according to Microsoft. The latest fix comes after a number of other problems were resolved this week.

A super-pressurized, 290-mile-long river is running under the ice sheet. That could be bad news for sea-level rise. From a report: For all its treacherousness and general inclination to kill you, Antarctica’s icy surface is fairly tranquil: vast stretches of miles-thick whiteness, with not a plant or animal to speak of. But way below the surface, where that ice meets land, things get wild. What scientists used to think was a ho-hum subglacial environment is in fact humming with hydrological activity, recent research is revealing, with major implications for global sea-level rise. Researchers just found that, at the base of Antarctica’s ice, an area the size of Germany and France combined is feeding meltwater into a super-pressurized, 290-mile-long river running to the sea. “Thirty years ago, we thought the whole of the ice pretty much was frozen to the bed,” says Imperial College London glaciologist Martin Siegert, coauthor of a new paper in Nature Geoscience describing the finding. “Now we’re in a position that we’ve just never been in before, to understand the whole of the Antarctic ice sheet.”

Antarctica’s ice is divided into two main components: the ice sheet that sits on land, and the ice shelf that extends off the coast, floating on seawater. Where the two meet — where the ice lifts off the bed and starts touching the ocean — is known as the grounding line. But the underside of all that ice is obscured. To find out what’s going on below, some scientists have hiked across glaciers while dragging ground-penetrating radar units on sleds — the pings travel through thousands of feet of ice and bounce off the underlying seawater, so the researchers can build detailed maps of what used to be hidden. Others are setting off explosions, then analyzing the seismic waves that come back to the surface to indicate whether there’s land or water below. Still others are lowering torpedo-shaped robots through boreholes to get unprecedented imagery of the underside of the floating ice shelf. Up in the sky, satellites can measure minute changes in surface elevation, which indicates the features below — a swell, for instance, might betray a subglacial lake.
