Researchers say structures made of the cells could potentially be used to clean up uranium from oceans, heal wounds, and more.
Your brain naturally ‘rewires’ itself as you age. But it doesn’t have to, at least not as quickly.
Astronomers at Caltech have used a machine learning algorithm to classify 1,000 supernovae completely autonomously. The algorithm was applied to data captured by the Zwicky Transient Facility, or ZTF, a sky survey instrument based at Caltech’s Palomar Observatory.
“We needed a helping hand, and we knew that once we trained our computers to do the job, they would take a big load off our backs,” says Christoffer Fremling, a staff astronomer at Caltech and the mastermind behind the new algorithm, dubbed SNIascore. “SNIascore classified its first supernova in April 2021, and, a year and a half later, we are hitting a nice milestone of 1,000 supernovae.”
ZTF scans the night skies every night to look for changes called transient events. This includes everything from moving asteroids to black holes that have just eaten stars to exploding stars known as supernovae. ZTF sends out hundreds of thousands of alerts a night to astronomers around the world, notifying them of these transient events. The astronomers then use other telescopes to follow up and investigate the nature of the changing objects. So far, ZTF data have led to the discovery of thousands of supernovae.
Integrating robots into walls, ceilings, furniture, and appliances could radically change our indoor spaces.
With the above in mind, projects looking to desalinate water in a more sustainable way will become increasingly important in the years ahead.
The idea of using waves to power desalination is not unique to the project being undertaken in the Canaries. In April, for example, the U.S. Department of Energy revealed the winners of the last stage of a competition focused on wave-powered desalination.
Back on the Canary Islands, Ocean Oasis said it would be looking to construct a second installation after testing at the PLOCAN facility had taken place. “In this phase, the prototype will be scaled with the capacity to produce water for consumption,” the company said.

To realize electronic operations beyond the von Neumann bottleneck, a new type of switch that can mimic self-learning is needed. Here, the authors demonstrate all-in-one-place logic and memory operations based on dynamic molecular switch that can emulate brain-like synaptic and Pavlovian response, bringing the field a step closer to molecular-scale hardware.
Phages probably picked up DNA-cutting systems from microbial hosts, and might use them to fight other viruses.
