Google patches two security vulnerabilities in Chrome for Windows, Mac, and Linux, both of which it says are under active exploitation.
In 2003, Lyon was just finishing school and working as a hired hacker. Companies tasked him with rooting out vulnerabilities in their systems, and he’d developed mapping tools for the job. His electronic sniffers would trace a network’s lines and nodes and report back what they found. Why not set them loose on the mother of all networks, he thought? So he did.
The resulting visualization recalled grand natural patterns, like networks of neurons or the large-scale structure of the universe. But it was at once more mundane and mind-boggling—representing, as it did, both a collection of mostly standard laptop and desktop computers connected to servers in run-of-the-mill office parks and an emerging technological force that was far more than the sum of it parts.

We may be on track to our own version of the Oasis after an announcement yesterday from Epic Games that it has raised $1 billion to put towards building “the metaverse.”
Epic Games has created multiple hugely popular video games, including Fortnite, Assassin’s Creed, and Godfall. An eye-popping demo released last May shows off Epic’s Unreal Engine 5, its next-gen computer program for making video games, interactive experiences, and augmented and virtual reality apps, set to be released later this year. The graphics are so advanced that the demo doesn’t look terribly different from a really high-quality video camera following someone around in real life—except it’s even cooler. In February Epic unveiled its MetaHuman Creator, an app that creates highly realistic “digital humans” in a fraction of the time it used to take.

Physicists from Swansea University are part of an international research collaboration which has identified a new technique for testing the quality of quantum correlations.
Quantum computers run their algorithms on large quantum systems of many parts, called qubits, by creating quantum correlations across all of them. It is important to verify that the actual computation procedures lead to quantum correlations of desired quality.
However, carrying out these checks is resource-intensive as the number of tests required grows exponentially with the number of qubits involved.
It may be possible in the future to use information technology where electron spin is used to store, process and transfer information in quantum computers. It has long been the goal of scientists to be able to use spin-based quantum information technology at room temperature. A team of researchers from Sweden, Finland and Japan have now constructed a semiconductor component in which information can be efficiently exchanged between electron spin and light at room temperature and above. The new method is described in an article published in Nature Photonics.
It is well known that electrons have a negative charge; they also have another property called spin. This may prove instrumental in the advance of information technology. To put it simply, we can imagine the electron rotating around its own axis, similar to the way in which the Earth rotates around its own axis. Spintronics—a promising candidate for future information technology—uses this quantum property of electrons to store, process and transfer information. This brings important benefits, such as higher speed and lower energy consumption than traditional electronics.
Developments in spintronics in recent decades have been based on the use of metals, and these have been highly significant for the possibility of storing large amounts of data. There would, however, be several advantages in using spintronics based on semiconductors, in the same way that semiconductors form the backbone of today’s electronics and photonics.
On April 10, 2021 NASA announced Ingenuity Mars Helicopter failed high-speed spin test causing reschedule of the first flight to no earlier than April 14. NASA explained that during a high-speed spin test of the rotors on Friday, the command sequence controlling the test ended early due to a “watchdog” timer expiration. This occurred as it was trying to transition the flight computer from ‘Pre-Flight’ to ‘Flight’ mode. The helicopter is safe and healthy and communicated its full telemetry set to Earth. The watchdog timer oversees the command sequence and alerts the system to any potential issues. It helps the system stay safe by not proceeding if an issue is observed and worked as planned. Ingenuity team is reviewing telemetry to diagnose and understand the issue. Following that, they will reschedule the full-speed test.

Elon Musk’s brain-chip Neuralink company is working on technology that could improve the lives of those with paralysis.
Circa 2014 essentially this could make endless computer chips from light.
Princeton researchers have managed to cause light to behave like a crystal within a specialized computer chip, according to a recent paper. This is the first time anyone has accomplished this effect in a lab.
Here’s why it’s so hard: Atoms can easily form solids, liquids, and gasses, because when they come into contact they push and pull on each other. That push and pull forms the underlying structure of all matter. Light particles, or photons, do not typically interact with one another, according to Dr. Andrew Houck, a professor of electrical engineering at Princeton and an author on the study. The trick of this research was forcing them to do just that.

MediaTek and Qualcomm may be the dominant players in the 5G smartphone SoC sector, but Chinese phone vendors Oppo and Xiaomi are mounting a challenge by developing their own chips. Shortages plaguing the semidoncutor industry are sending firms scrambling for supply. NOR flash chipmakers say that more of their clients are now willing to strike long-term supply contracts. For backend firms, demand from MCU clients remains robust.
Unisoc, Oppo, Xiaomi gearing up for new 5G mobile chips roll-outs: Oppo and Xiaomi will introduce their in-house-developed sub-6GHz 5G chip solutions between late 2021 and early 2022, joining fabless chipmaker Unisoc in competing against chip vendors such as Qualcomm and MediaTek, according to industry sources in Taiwan.
NOR flash chipmakers see more customers eager for long-term deals: Taiwan-based NOR flash chipmakers have seen more of their clients eager to strike long-term supply agreements, according to industry sources.
Neuralink, co-founded by Elon Musk in 2016, has revealed a macaque with chips embedded on each side of its brain, playing a mind-controlled version of the 1972 video game, Pong.
Although established in 2016, Neuralink remained secretive about its work until July 2019, when Musk presented his concept for a new brain–machine interface (BMI). Not only would this help physically diseased or injured people, Musk believed it could also treat mental illness – and even be used by healthy individuals who might wish to enhance themselves.
A prototype in August 2020 demonstrated the Neuralink technology in a pig. This coin-sized chip, featuring a read/write link, contained 1024 channels with a wireless megabit data rate and all-day battery life. Brain signals conveying the pig’s sense of smell could be seen in real time. The FDA had by then approved it as a breakthrough device, allowing use in limited human trials under the US federal guidelines for testing medical devices.
