Virtual meetings that are a bit more meeting-like.

Zoom is rolling out a video background feature called Immersive View that could make video calls feel a bit more like an office meeting — or at least look a lot more like one. Zoom announced the feature last year at its Zoomtopia conference, but now it’s actually available for Free and Pro accounts attending meetings and webinars with up to 25 participants.

Immersive View builds on the virtual background features Zoom already has, but focuses on actually placing meeting attendees in a realistic-looking location, rather than just switching out a flat background. Meeting hosts can enable Immersive View from the same menu where you can find Speaker View and Gallery View; from there, Zoom will automatically place attendees in a variety of built-in virtual scenes like a board room or auditorium, or the meeting host can manually place them themselves.

Tesla beat expectations on revenue and earnings in Q1, but the stock dropped slightly after hours.

Two important sars-cov-2/covid-19 links.

An experimental COVID-19 vaccine could potentially provide universal protection against future COVID variants as well as other coronaviruses—maybe even the ones responsible for the common cold. And it’s dirt cheap—less than $1 a dose, researchers say.

DDR5 memory production is finally picking up speed as several manufacturers have finalized their mainstream designs for the next-generation standard. The DDR5 memory standard will be utilized by upcoming Intel (Alder Lake) & AMD (Raphael) platforms which are expected to launch later this year.

Jiahe Jinwei has announced that it has received the first batch of DDR5 memory modules from its assembly line based in the Shenzhen Pingshan factory. The memory modules are now being mass-produced and are expected to launch later this year with the next-generation platforms from Intel and AMD. Intel is said to take a lead in offering the next-gen memory support first on its next-gen Alder Lake platform comprising of the Z690 chipset-based motherboards as reported here.

During implicit learning, the authors find that sensory representations in mouse auditory cortex evolve over time, rotating into orthogonal memory representations. This allows short-term memories to avoid interference from new sensory inputs.

It can track objects the size of a golf ball traveling at up 30000 kilometers per hour in LEO.

There’s a new giant space radar in Costa Rica that can track orbital debris as small as two centimeters. It was built by LeoLabs, a company that provides commercial radar tracking services for objects in Low Earth Orbit, which has declared the site fully operational less than a year after breaking ground. LeoLabs CEO Dan Ceperley said it’s the “most advanced commercial space radar of its kind” — one that’s capable of tracking objects the size of a golf ball traveling at up 30000 kilometers per hour.

The radar can keep an eye on both active satellites and space junk, which make up the vast majority of man-made objects found in LEO. They’re also the risks LeoLabs’ customers — made up of satellite operators, defense, space and regulatory agencies, insurance and scientific institutions — want to keep tabs on.
