Are the big ice sheets in Antarctica stable in the face of the warming we've already committed to? That's more serious question than it might sound. The continent is thought to hold enough ice to raise ocean levels by over 55 meters if it were to melt—enough to drown every single bit of coastal infrastructure we have and send people migrating far inland from the present-day shoreline.
But the melting of this ice is a complicated process, one that depends on things like the dynamics of glaciers as they push through coastal hills, the shape of the seafloor where the ice meets it, and the slope of the basins the ice sheets sit in. It's tough to reason out how much ice would be lost for a given bit of warming. As a result, we're left with historical comparisons: the last time it warmed by that amount, how much ice did we lose?
This week, we got some new information on this question courtesy of a detailed study of Antarctica's Wilkes Subglacial Basin. The work showed that it wasn't so much the amount of warming the ice experienced; it was how long it stayed warm.
Amazon seems to have given us a glimpse into some of its new, unreleased products. Listings on Amazon UK show a new Echo Sub, a subwoofer designed to work with Echo speakers, and a new Amazon Smart Plug, a socket adapter with Alexa capabilities, both with an availability date of October 11. Amazon has since removed the listings, but reports from Pocket-lint show images and details of the two new devices.
The Echo Sub looks like a fatter version of Amazon's Echo speaker, almost like a clone of Apple's HomePod. The wireless subwoofer includes a 6-inch down-firing woofer and 100W of bass, tech that would certainly improve the quality of existing Echo speakers. Some complained after Amazon released the updated version of the original Echo last year, claiming its sound quality was subpar.
Listed within the device's description is stereo pairing, a feature that hasn't been available to Echo speakers yet. Currently, users can only group multiple speakers together to fill a room with sound, but they won't get that rich, complex left/right stereo sound. It appears that will be possible with the Echo Sub connected to two compatible Echo devices.

With the advent of toy quantum computers, I’ve been less interested in reporting on the developments of new qubit systems. That doesn’t mean I’ve been ignoring them. Instead, i'm seeing that lots of different types of qubits have deficiencies that are likely to lead to their abandonment at some point. Until I see those overcome, I tend to pay less attention.
Researchers are now reporting that they have overcome one of the major drawbacks in a silicon-doped diamond (SiV-) qubit. The qubit is no longer destroyed so easily and can be manipulated in ways that might make it quite flexible.
Qubits based around a defect in a crystal—in this case, caused by the placement of silicon in an otherwise all-carbon crystal—have been around for a while. But the qubit is way too sensitive to tiny vibrations called phonons. Phonons are basically the crystal’s way of moving heat around, so the amount of energy in a phonon is really tiny and hard to get rid of. Qubits that are readily destroyed by phonons are probably not very useful.
Expect to see plenty of new Alexa-powered devices -- and maybe even a microwave.
