CRISPR-Cas is used broadly in research and medicine to edit, insert, delete or regulate genes in organisms. TnpB is an ancestor of this well-known “gene scissors” but is much smaller and thus easier to transport into cells.

Using protein engineering and AI algorithms, University of Zurich researchers have now enhanced TnpB capabilities to make DNA editing more efficient and versatile, paving the way for treating a genetic defect for high cholesterol in the future. The work has been published in Nature Methods.

CRISPR-Cas systems, which consist of protein and RNA components, we...

Engineers 3D Print Sturdy Glass Bricks for Building Structures

In the middle of Killian Court, a stout pyramid of the glass bricks is four layers tall, and looks about 15 feet across and four feet high.

The interlocking bricks, which can be repurposed many times over, can withstand similar pressures as their concrete counterparts. Engineers developed a new kind of reconfigurable masonry made from 3D-printed, recycled glass. The bricks could be reused many times over in building facades and internal walls.

What if construction materials could be put together and taken apart as easily as LEGO bricks? Such reconfigurable masonry would be disassembled at the end of a building’s lifetime and reassembled into a new structure, in a sustainable cycle that could supply generations of buildings using the same physical building blocks.

That’s the idea behind cir...

Flexible Circuits made with Silk and Graphene on the horizon

By controlling silk protein nanostructure for the first time, scientists pave the way for advanced microelectronic and computing applications. Ultra-thin layers of silk deposited on graphene in perfect alignment represent a key advance for the control needed in microelectronics and advanced neural network development.

After thousands of years as a highly valuable commodity, silk continues to surprise. Now it may help usher in a whole new direction for microelectronics and computing.

While silk protein has been deployed in designer electronics, its use is currently limited in part because silk fibers are a messy tangle of spaghetti-like strands.

Now, a research team led by scientists at the Department of Energy’s Pacific Northwest National Laboratory has tamed the tangle...

New Algorithm Helps Enhance LLM Collaboration for Smarter, more Efficient Solutions

Ever been asked a question you only knew part of the answer to? To give a more informed response, your best move would be to phone a friend with more knowledge on the subject.

This collaborative process can also help large language models (LLMs) improve their accuracy. Still, it’s been difficult to teach LLMs to recognize when they should collaborate with another model on an answer...
