The contrast between the James Webb Space Telescope.
The James Webb Space Telescope (JWST or Webb) is an orbiting infrared observatory that will complement and extend the discoveries of the Hubble Space Telescope. It covers longer wavelengths of light, with greatly improved sensitivity, allowing it to see inside dust clouds where stars and planetary systems are forming today as well as looking further back in time to observe the first galaxies that formed in the early universe.
The James Webb and Hubble space telescopes have combined forces to image a cluster of galaxies 4.3 billion light-years away in one of the most colorful pictures of the universe ever taken.
A new article published in Opto-Electronic Science reviews the fundamentals and applications of optically trapped optical nanoparticles. Optical nanoparticles are one of the key elements of photonics. They not only allow optical imaging of a plethora of systems (from cells to microelectronics), but also behave as highly sensitive remote sensors.
The success of optical tweezers in isolating and manipulating individual optical nanoparticles has been recently demonstrated. This has opened the door to high-resolution, single-particle scanning and sensing.
The most relevant results in the quickly growing fields of optical trapping of individual optical nanoparticles are summarized by this article. According to different materials and their optical properties, the optical nanoparticles are classified into five families: plasmonic nanoparticles, lanthanide-doped nanoparticles, polymeric nanoparticles, semiconductor nanoparticles, and nanodiamonds. For each case, the main advances and applications have been described.
This paper characterizes two distinct philosophies underlying previous work on how Bayesian computations are linked to neural data, highlighting how different theories may be motivated by different tacit assumptions and thereby explain different data.
Prof. Sakhrat Khizroev (University of Miami) discusses how new and advanced materials can be used for interfacing machines and the human brain!

Japan’s Nippon Telegraph and Telephone Corporation (NTT) is applying its Deep Anomaly Surveillance (DeAnoS) artificial intelligence tool, originally designed for telecom networks, to predict anomalies in nuclear fusion reactors.
DeAnoS is like a detective, trying to understand which part of the equation is making things weird.
Atomic fusion reactors are at the forefront of scientific innovation, harnessing the enormous energy released by atomic nuclei fusion. This process, which is similar to the Sun’s power source, involves the union of two light atomic nuclei, which results in the development of a heavier nucleus and the release of a massive quantity of energy.
DeepMind’s new machine learning algorithm takes less than a minute to make its forecasts and can run on a desktop. But it won’t replace traditional forecasts anytime soon.
A new Mirai-based malware botnet named ‘InfectedSlurs’ has been exploiting two zero-day remote code execution (RCE) vulnerabilities to infect routers and video recorder (NVR) devices.
The malware hijacks the devices to make them part of its DDoS (distributed denial of service) swarm, presumably rented for profit.
The discovery of ‘InfectedSlurs’ comes from Akamai, who first spotted it on its honeypots in late October 2023. However, the botnet’s initial activity dates back to late 2022.
The OpenAI saga appears to be in a holding pattern, at least for the moment, as hundreds of employees threaten to leave en masse if the board doesn’t resign and reinstate Sam Altman as CEO of the artificial intelligence powerhouse.
Microsoft CEO Satya Nadella made it clear in interviews Monday that the company wouldn’t be opposed to Altman returning to OpenAI, with changes to the board, including provisions to keep Microsoft from being surprised in the manner it was on Friday, learning of Altman’s ouster minutes before the rest of the world.
“One thing, I’ll be very, very clear, is we’re never going to get back into a situation where we get surprised like this, ever again. … That’s done,” Nadella said on a joint episode of the Pivot and On with Kara Swisher podcasts.
