Researchers have developed a new way to apply antireflective (AR) coatings to 3D printed multi-lens systems as small as 600 microns in diameter. Because these coatings help minimize light losses due to reflection, they are critical for making high-quality 3D printed systems consisting of multiple microlenses.

“Our new method will benefit any 3D printed complex optical system that uses multiple lenses,” said research team leader Harald Giessen from the University of Stuttgart in Germany. “However, it is especially useful for applications such as miniature fiber endoscopes, which require high-quality optics and are used for imaging under less-than-ideal lighting conditions.”

The researchers used a microscope to acquire tilted-view images of a 600-micron-diameter doublet lens system 3D printed on a 1×1 cm² glass slide. The doublet lens system is visible as the small dot in the center of the glass slide. The coin is included for scale. (Image: Moritz Flöss, University of Stuttgart)

The number of unexplained severe hepatitis cases in children continues to increase. Health agencies said there are currently 170 cases worldwide. One theory suggests the spread could be linked to adenovirus. Health officials are looking into whether Covid lockdowns could have played a role, with kids less exposed to common infections.

Rocket Lab has been trying to actualize its mission called “There and Back Again.” The company tweeted on Friday that it was targeting May 1 or May 2 for the launch.

Tenet Healthcare Corporation recently experienced a cybersecurity incident in April 2022, which resulted in a temporary disruption to a subset of acute care operations.

The report from Tenet comes on the heels of telephone and computer problems occurring at St. Mary’s Medical Center and Good Samaritan Medical Center in West Palm Beach Florida, that were reported by WPTV NewsChannel 5. Tenet health is the parent company for both of the medical centers.

Patients and staff have contacted WPTV NewsChannel 5 expressing concerns about patient care tied to limits of electronic charting and their inability to communicate by telephone.

Groundbreaking new research suggests gamma-ray bursts are caused by a star’s collapsing magnetic field.

The same goes for artificial intelligence (AI) and machine learning (ML) models.

And just as the human brain created AI and ML models that grow increasingly sophisticated by the day, these systems are now being applied to study the human brain itself. Specifically, such studies are seeking to enhance the capabilities of AI systems and more closely model them after brain functions so that they can operate in increasingly autonomous ways.

Researchers at Meta AI have embarked on one such initiative. The research arm of Facebook’s parent company today announced a long-term study to better understand how the human brain processes language. Researchers are looking at how the brain and AI language models respond to the same spoken or written sentences.

Pilot tests of ‘game-changing’ salt batteries are set to take place in homes in France, Poland and the Netherlands this year.

“It is not yet a product, but everything is now ready to be tested for the first time in a real-world situation,” said Olaf Adan, a professor at Eindhoven University of Technology.

“While the potential is great, we have also seen many great potential technologies that have not made it. So we’re going to keep our feet on the ground and take this one step at a time.”

The West Japan Rail Company (or JR West) unveiled its Gundam-style heavy equipment robot for carrying out repairs.

The robot takes on the appearance of a humanoid upper body mounted on the end of a hydraulic crane arm, which rides around on the rail system atop a specially braced rail car. The rail car can deploy stabilizing legs when it arrives at its destination along the line, allowing the robot to manipulate heavy equipment around the rail system instead of workers “to improve productivity and safety.”
