Engineered Bacteria Eat Waste Plastic and Make Spider Silk — “Nature’s Kevlar”

Posted by in category: sustainability

For the first time, researchers have used bacteria to “upcycle” waste polyethylene.

Move over Spider-Man: Researchers at Rensselaer Polytechnic Institute have developed a strain of bacteria that can turn plastic waste into a biodegradable spider silk with multiple uses.

As AI Destroys Search Results, Google Fires Workers in Charge of Improving It

Posted by in categories: information science, robotics/AI

Amid a massive wave of tech company layoffs in favor of AI, Google is firing thousands of contractors tasked with making its namesake search engine work better.

As Vice reports, news of the company ending its contract with Appen — a data training firm that employs thousands of poorly paid gig workers in developing countries to maintain, among other things, Google’s search algorithm — coincidentally comes a week after a new study found that the quality of its search engine’s results has indeed gotten much worse in recent years.

Back in late 2022, journalist Cory Doctorow coined the term “enshittification” to refer to the demonstrable worsening of all manner of online tools, which he said was by design as tech giants seek to extract more and more money out of their user bases. Google Search was chief among the writer’s examples of the enshittification effect in a Wired article published last January, and as the new study out of Germany found, that effect can be measured.

Japan’s moon lander comes back to life

Posted by in categories: solar power, space, sustainability

Japan’s moon lander has come back to life, the space agency said Monday, enabling the craft to proceed with its mission of investigating the lunar surface despite its rocky start.

The surprise announcement was a boost to Japan’s space program, nine days after the Smart Lander for Investigating Moon (SLIM) touched down at a wonky angle that left its facing the wrong way.

“Last evening we succeeded in establishing communication with SLIM, and resumed operations!” JAXA said on social media platform X, posting a grainy image of a lunar rock known as a “toy poodle”

The most powerful AI processing supercomputer in the world is set to be built in Germany, and planned to become operational within a mere year. Crikey

Posted by in categories: robotics/AI, supercomputing

AI processing can take a huge amount of computing power, but by the looks of this latest joint project from the Jülich Supercomputing Center and French computing provider Eviden, power will not be in short supply.


“But can it run Crysis” is an old gag, but I’m still going to see if I get away with it.

Acoustic tweezers manipulate cells with sound waves

Posted by in categories: 3D printing, bioengineering, biotech/medical, chemistry, life extension, neuroscience

Engineers at MIT, Penn State University, and Carnegie Mellon University have devised a way to manipulate cells in three dimensions using sound waves. These “acoustic tweezers” could make possible 3D printing of cell structures for tissue engineering and other applications, the researchers say.

Designing tissue implants that can be used to treat human disease requires precisely recreating the natural tissue architecture, but so far it has proven difficult to develop a single method that can achieve that while keeping cells viable and functional.

“The results presented in this paper provide a unique pathway to manipulate biological cells accurately and in three dimensions, without the need for any invasive contact, tagging, or biochemical labeling,” says Subra Suresh, president of Carnegie Mellon and former dean of engineering at MIT. “This approach could lead to new possibilities for research and applications in such areas as regenerative medicine, neuroscience, tissue engineering, biomanufacturing, and cancer metastasis.”

Finding and Erasing Quantum Computing Errors in Real-Time

Posted by in categories: computing, quantum physics

With a quick pulse of light, researchers can now find and erase errors in real time.

Researchers have developed a method that can reveal the location of errors in quantum computers, making them up to ten times easier to correct. This will significantly accelerate progress towards large-scale quantum computers capable of tackling the world’s most challenging computational problems, the researchers said.

Led by Princeton University ’s Jeff Thompson, the team demonstrated a way to identify when errors occur in quantum computers more easily than ever before. This is a new direction for research into quantum computing hardware, which more often seeks to simply lower the probability of an error occurring in the first place.

Elon Musk’s Neuralink implants brain chip in first human

Posted by in categories: biotech/medical, chemistry, computing, Elon Musk, neuroscience

Jan 29 (Reuters) — The first human patient has received an implant from brain-chip startup Neuralink on Sunday and is recovering well, the company’s billionaire founder Elon Musk said.

“Initial results show promising neuron spike detection,” Musk said in a post on the social media platform X on Monday.

Spikes are activity by neurons, which the National Institute of Health describes as cells that use electrical and chemical signals to send information around the brain and to the body.
