WHEN OLIVER TSCHAUNER AND COLLEAGUES dusted off a sample of volcano-ejected diamond found in a South African mine, they had no idea that they were holding the first-ever natural sample of a new high-pressure mineral from deep within Earth.

While minuscule, researchers predict that this mineral is responsible for the movement of crucial components like rare earth metals and radioactive isotopes through the Earth’s mantle. To figure this out, the team turned to X-ray beams and lasers.


Using x-rays and lasers, scientists have analyzed the second-ever high-pressure mineral extracted from the earth’s lower mantle.

WASHINGTON, December 24, 2021 – Former Secretary of State Henry Kissinger says that further use of artificial intelligence will call into question what it means to be human, and that the technology cannot solve all those problems humans fail to address on their own.

Kissinger spoke at a Council on Foreign Relations event highlighting his new book “The Age of AI: And Our Human Future” on Monday along with co-author and former Google CEO Eric Schmidt in a conversation moderated by PBS NewsHour anchor Judy Woodruff.

Schmidt remarked throughout the event on unanswered questions about AI despite common use of the technology.

Scientists have discovered new cradle of life with several different species hidden underneath the ice shelf in Antarctica.


When you think of Antarctica, the first thing that comes to mind is most likely that it’s a frozen wasteland. Sure, there is some life in the Antarctic world. But for the most part, the land is mostly made up of a below-freezing environment. Now, though, scientists have uncovered new life underneath the ice shelf.

According to a new study, scientists have discovered more marine life than previously expected under the Antarctic ice shelf. The study was published this past week in the journal Current Biology.

Microsoft is urging customers to patch two Active Directory domain controller bugs after a PoC tool was publicly released on Dec. 12.

A proof-of-concept tool has been published that leverages two Windows Active Directory bugs fixed last month that, when chained, can allow easy Windows domain takeover.

In a Monday alert, Microsoft urged organizations to immediately patch the pair of bugs, tracked as CVE-2021–42287 and CVE-2021–42278, both of which were fixed in its November 2021 Patch Tuesday release.

Some of the best circuits to drive AI in the future may be analog, not digital, and research teams around the world are increasingly developing new devices to support such analog AI.

The most basic computation in the deep neural networks driving the current explosion in AI is the multiply-accumulate (MAC) operation. Deep neural networks are composed of layers of artificial neurons, and in MAC operations, the output of each one of these layers is multiplied by the values of the strengths or “weights” of their connections to the next layer, which then sums up these contributions.

Modern computers have digital components devoted to MAC operations, but analog circuits theoretically can perform these computations for orders of magnitude less energy. This strategy—known as analog AI, compute-in-memory or processing-in-memory—often performs these multiply-accumulate operations using non-volatile memory devices such as flash, magnetoresistive RAM (MRAM), resistive RAM (RRAM), phase-change memory (PCM) and even more esoteric technologies.
