What’s New In Tech

AI systems generate original protein

Scientists have created an AI system capable of generating artificial enzymes from scratch. Salesforce Research developed an AI program, called ProGen, which uses next-token prediction to assemble amino acid sequences into artificial proteins. In laboratory tests, some of these enzymes worked as well as those found in nature, even when their artificially generated amino acid sequences diverged significantly from any known natural protein.

‘Smart’ walking stick could help visually impaired

Engineers at the University of Colorado Boulder are using artificial intelligence to develop a new kind of walking stick for people who are blind or visually impaired to navigate tasks in a world designed for sighted people. With a combination of AI and computer vision, these sticks can help people do grocery shopping and choose a seat at a public place.

Speed gene-editing made possible with new AI tool

An artificial intelligence program may enable the first simple production of customizable proteins called zinc fingers to treat diseases by turning genes on and off. The researchers who designed the tool say it promises to accelerate the development of gene therapies on a large scale.

Ultrasound on the go with wearable sensor

Engineers and physicians have developed a wearable ultrasound device that can assess both the structure and function of the human heart. The portable device, which is roughly the size of a postage stamp, can be worn for up to 24 hours and works even during strenuous exercise.
