When Nicole Oliveira was just learning to walk, she would throw up her arms to reach for the stars in the sky.
Today, at just eight years of age, the Brazilian girl is known as the world’s youngest astronomer, looking for asteroids as part of a NASA-affiliated program, attending international seminars and meeting with her country’s top space and science figures.
In Oliveira’s room, filled with posters of the Solar System, miniature rockets and Star Wars figures, Nicolinha, as she is affectionately known, works on her computer studying images of the sky on two large screens.
Reversible system can flip the magnetic orientation of particles with a small voltage; could lead to faster data storage and smaller sensors.
Most of the magnets we encounter daily are made of “ferromagnetic” materials. The north-south magnetic axes of most atoms in these materials are lined up in the same direction, so their collective force is strong enough to produce significant attraction. These materials form the basis for most of the data storage devices in today’s high-tech world.
Less common are magnets based on ferrimagnetic materials, with an “i.” In these, some of the atoms are aligned in one direction, but others are aligned in precisely the opposite way. As a result, the overall magnetic field they produce depends on the balance between the two types — if there are more atoms pointed one way than the other, that difference produces a net magnetic field in that direction.
At the SAS 2021 security conference today, analysts from security firm Kaspersky Lab have published details about a new Chinese cyber-espionage group that has been targeting high-profile entities across South East Asia since at least July 2020.
Named GhostEmperor, Kaspersky said the group uses highly sophisticated tools and is often focused on gaining and keeping long-term access to its victims through the use of a powerful rootkit that can even work on the latest versions of Windows 10 operating systems.
“We observed that the underlying actor managed to remain under the radar for months,” Kaspersky researchers explained today.
As part of the launch of the new Loihi 2 chip, built on a pre-production version of Intel’s 4 process node, the Intel Labs team behind its Neuromorphic efforts reached out for a chance to speak to Mike Davies, the Director of the project. Now it is perhaps no shock that Intel’s neuromorphic effo…
We’ve been eagerly following the development of the WiFiWart for some time now, as a quad-core Cortex-A7 USB phone charger with dual WiFi interfaces that runs OpenWrt sounds exactly like the sort of thing we need in our lives. Unfortunately, we’ve just heard from [Walker] that progress on the project has been slowed down indefinitely by crippling chip shortages.
At this point, we’ve all heard how the chip shortage is impacting the big players out there. It makes sense that automakers are feeling the pressure, since they are buying literally millions of components at a clip. But stories like this are a reminder that even an individual’s hobby project can be sidelined by parts that are suddenly 40 times as expensive as they were when you first put them in your bill of materials.
In this particular case, [Walker] explains that a power management chip you could get on DigiKey for $1.20 USD a few months ago is now in such short supply that the best offer he’s found so far is $49.70 a pop from an electronics broker in Shenzhen. It sounds like he’s going to bite the bullet and buy the four of them (ouch) that he needs to build a working prototype, but obviously it’s a no go for production.
The 2022 Cadillac Escalade will no longer come with the company’s hands-free driving system, Super Cruise, because of the ongoing global chip shortage. Cadillac is suspending the feature on other new vehicles, too.

In a new study from Skoltech and the University of Kentucky, researchers found a new connection between quantum information and quantum field theory. This work attests to the growing role of quantum information theory across various areas of physics. The paper was published in the journal Physical Review Letters.
Quantum information plays an increasingly important role as an organizing principle connecting various branches of physics. In particular, the theory of quantum error correction, which describes how to protect and recover information in quantum computers and other complex interacting systems, has become one of the building blocks of the modern understanding of quantum gravity.
“Normally, information stored in physical systems is localized. Say, a computer file occupies a particular small area of the hard drive. By “error” we mean any unforeseen or undesired interaction which scrambles information over an extended area. In our example, pieces of the computer file would be scattered over different areas of the hard drive. Error correcting codes are mathematical protocols that allow collecting these pieces together to recover the original information. They are in heavy use in data storage and communication systems. Quantum error correcting codes play a similar role in cases when the quantum nature of the physical system is important,” Anatoly Dymarsky, Associate Professor at the Skoltech Center for Energy Science and Technology (CEST), explains.
