Scientists Create Programmable, Autonomous Robots Smaller Than a Grain of Salt
Researchers at the University of Pennsylvania and University of Michigan "have created the world's smallest fully programmable, autonomous robots," according to a recent announcement.
The announcement calls them "microscopic swimming machines that can independently sense and respond to their surroundings, operate for months and cost just a penny each."
Barely visible to the naked eye, each robot measures about 200 by 300 by 50 micrometers, smaller than a grain of salt. Operating at the scale of many biological microorganisms, the robots could advance medicine by monitoring the health of individual cells and manufacturing by helping construct microscale devices. Powered by light, the robots carry microscopic computers and can be programmed to move in complex patterns, sense local temperatures and adjust their paths accordingly... "We've made autonomous robots 10,000 times smaller," says Marc Miskin, Assistant Professor in Electrical and Systems Engineering at Penn Engineering and the papers' senior author. "That opens up an entirely new scale for programmable robots."
The announcement describes them as "the first truly autonomous, programmable robots at this scale" (as described in two recent academic articles). The team had to design a new propulsion system that utilized the unique locomotion physics in the microscopic realm, according to the university's announcement. So the robots "generate an electrical field that nudges ions in the surrounding solution."
Those ions, in turn, push on nearby water molecules, animating the water around the robot's body. "It's as if the robot is in a moving river," says Miskin, "but the robot is also causing the river to move." The robots can adjust the electrical field that causes the effect, allowing them to move in complex patterns and even travel in coordinated groups, much like a school of fish, at speeds of up to one body length per second...
To be truly autonomous, a robot needs a computer to make decisions, electronics to sense its surroundings and control its propulsion, and tiny solar panels to power everything, and all that needs to fit on a chip that is a fraction of a millimeter in size. This is where David Blaauw's team at the University of Michigan came into action... The robots are programmed by pulses of light that also power them. Each robot has a unique address that allows the researchers to load different programs on each robot. "This opens up a host of possibilities," adds Blaauw, "with each robot potentially performing a different role in a larger, joint task."

Microbes In Space Mutated and Developed a Remarkable Ability
"A box full of viruses and bacteria has completed its return trip to the International Space Station," reports ScienceAlert, "and the changes these 'bugs' experienced in their travels could help us Earthlings tackle drug-resistant infections..."
Scientists aboard the space station incubated different combinations of bacteria and phages for 25 days, while the research team led by biochemist Vatsan Raman carried out the same experiments in Madison, down here on Earth. "Space fundamentally changes how phages and bacteria interact: infection is slowed, and both organisms evolve along a different trajectory than they do on Earth," the researchers explain. In the weightlessness of space, bacteria acquired mutations in genes involved in the microbe's stress response and nutrient management. Their surface proteins also changed. After a slow start, the phages mutated in response, so they could continue binding to their victims.
The team found that certain space-specific phage mutations were especially effective at killing Earth-bound bacteria responsible for urinary tract infections (UTIs). More than 90 percent of the bacteria responsible for UTIs are antibiotic-resistant, making phage treatments a promising alternative.

Author of Systemd Quits Microsoft To Prove Linux Can Be Trusted
Lennart Poettering has left Microsoft to co-found Amutable, a new Berlin-based company aiming to bring cryptographically verifiable integrity and deterministic trust guarantees to Linux systems. He said in a post on Mastodon that his "role in upstream maintenance for the Linux kernel will continue as it always has." Poettering will also continue to remain deeply involved in the systemd ecosystem. The Register reports: Linux celeb Lennart Poettering has left Microsoft and co-founded a new company, Amutable, with Chris Kuhl and Christian Brauner. Poettering is best known for systemd. After a lengthy stint at Red Hat, he joined Microsoft in 2022. Kuhl was a Microsoft employee until last year, and Brauner, who also joined Microsoft in 2022, left this month. [...]
It is unclear why Poettering decided to leave Microsoft. We asked the company to comment but have not received a response. Other than the announcement of systemd 259 in December, Poettering's blog has been silent on the matter, aside from the announcement of Amutable this week. In its first post, the Amutable team wrote: "Over the coming months, we'll be pouring foundations for verification and building robust capabilities on top."
It will be interesting to see what form this takes. In addition to Poettering, the lead developer of systemd, Amutable's team includes contributors and maintainers for projects such as Linux, Kubernetes, and containerd. Its members are also very familiar with the likes of Debian, Fedora, SUSE, and Ubuntu.

Linux Gaming Developers Join Forces To Form the Open Gaming Collective
A group of Linux gaming-focused distros and developers have formed the Open Gaming Collective to pool work on shared components like kernels, input systems, and Valve tooling. The Verge reports: Universal Blue, developer of the gaming-focused Linux distribution Bazzite, announced on Wednesday that its helping to form the OGC with several other groups, which will collaborate on improvements to the Linux gaming ecosystem and âoecentralize efforts around critical components like kernel patches, input tooling, and essential gaming packages such as gamescope." The other founding members of the OGC include Nobara, ChimeraOS, Playtron, Fyra Labs, PikaOS, ShadowBlip, and Asus Linux.
[...] It's worth noting that this will mean some changes to Bazzite, which is switching to the OGC kernel, replacing HHD with InputPlumber as its input framework, and integrating features like RGB and fan control into the Steam UI. Bazzite also added that, "We'll be sharing patches we've made to various Valve packages with the OGC and attempting to upstream everything we can."

Nvidia GeForce NOW Is Now Available Natively On Linux
NVIDIA has officially launched a native GeForce NOW client for Linux as a Flatpak, giving Linux gamers access to cloud-rendered RTX gaming. Phoronix reports: While confined to a Flatpak, for now NVIDIA is just "officially" supporting it on Ubuntu 24.04 LTS and later. Granted, thanks to Flatpak it should run on other non-Ubuntu distributions too but in terms of the official support and where they are qualifying their builds they are limiting it just to Ubuntu 24.04 LTS and later. [...] At launch the Flatpak build is also just for x86_64 Linux with no AArch64 Linux builds or similar at this time.
Running GeForce NOW on Linux while games are rendered in NVIDIA's cloud with Blackwell GPUs, you still need to be using a modern GPU with H.264 or H.265 Vulkan Video support NVIDIA isn't yet supporting Vulkan Video AV1 with GeForce NOW on Linux but just H.264/H.265. If you are using NVIDIA graphics the NVIDIA R580 series or newer is recommended while using the X.Org session. If you are using Intel or AMD Radeon graphics, Mesa 24.2+ is recommended and using the Wayland session.
When you are up and running with GeForce NOW on Linux, you have access to over 4,500 games. The free tier of GeForce NOW provides standard access to the gaming servers and limited session caps for an introductory-level experience. It's with the performance tier where you can enjoy RTX ray-tracing and 1440p @ 60 FPS performance and up to six hour sessions. With GeForce NOW's Ultimate tier is where you are running on GeForce RTX 5080 GPU servers with support for up to 5K @ 120 FPS gaming or 1080p @ 360 FPS with up to eight hour gaming sessions in length.
