Microplastics have been a persistent environmental problem, and it is now known that microplastics have permeated the terrestrial, freshwater, and marine ecosystems. Water treatment plants provide a viable solution for the removal of microplastics from the environment. However, until now, these plants have not been able to sufficiently filter out tiny microplastics in wastewater.

In the SimConDrill project, Fraunhofer ILT has joined forces with industrial partners to build a maintenance-free filter that stops microplastics in wastewater treatment. The challenge was to drill as many holes as possible, as small as possible, in a steel foil in the shortest time possible, says project manager Andrea Lanfermann.

Fraunhofer ILT engineers used the multi-beam process – in which a matrix of identical beams is generated from a laser beam via a special optical system – with an ultrashort-pulse laser (TruMicro 5,280 Femto Edition) to drill holes simultaneously with 144 beams.

In the first test, the fine powder from 3D printers was filtered from contaminated water. The setup is now being tested in a wastewater treatment plant under real conditions.

Hackers so far are focusing on decentralized finance (DeFi) projects to steal crypto this year, a new report found, a reversal from 2021 when they used scams and online fraud for most of their exploits.

So far, investors have lost over $1.22 billion to hackers in the first three months of the year, nearly eight times more than the $154 million lost in the first quarter of 2021, according to crypto security firm Immunefi. Ninety-nine percent of those losses were from software exploits, the report found, specifically the hacks against Wormhole and Ronin.

This is not an anomaly, experts warn. It’s likely this kind of nefarious activity will become more common, while scamming of investors could wane.

An exoplanet a whopping 17,000 light-years from Earth has been found hiding in data collected by the now-retired Kepler Space Telescope.

It’s the most distant world ever picked up by the planet-hunting observatory, twice the distance of its previous record. Fascinatingly, the exoplanet is almost an exact twin of Jupiter – of similar mass, and orbiting at almost the same distance as Jupiter’s distance from the Sun.

Named K2-2016-BLG-0005Lb, it represents the first exoplanet confirmed from a 2016 data run that detected 27 possible objects using a technique called gravitational microlensing rather than Kepler’s primary detection method. The discovery has been submitted to the Monthly Notices of the Royal Astronomical Society, and is available on preprint server arXiv.

Revolutionary tool will meet future pandemics with accelerated response.

A new tool speeds up development of vaccines and other pharmaceutical products by more than one million times while minimizing costs.

In search of pharmaceutical agents such as new vaccines, industry will routinely scan thousands of related candidate molecules. A novel technique allows this to take place on the nano scale, minimizing use of materials and energy. The work is published in the prestigious journal Nature Chemistry.

COLORADO SPRINGS – Lockheed Martin on April 4 released the technical specifications of a docking adapter that could be used by manufacturers to make satellites interoperable and easier to update on orbit with new technology.

The technical data for the Mission Augmentation Port (MAP) can be used by designers to develop their own docking adapters, said Lockheed Martin.

The company used the MAP standard to design its own docking device, called Augmentation System Port Interface (ASPIN).

Scientists at The University of Texas at Austin have redesigned a key component of a widely used CRISPR-based gene-editing tool, called Cas9, to be thousands of times less likely to target the wrong stretch of DNA while remaining just as efficient as the original version, making it potentially much safer.

Other labs have redesigned Cas9 to reduce off-target interactions, but so far, all these versions improve accuracy by sacrificing speed. SuperFi-Cas9, as this new version has been dubbed, is 4,000 times less likely to cut off-target sites but just as fast as naturally occurring Cas9. Bravo says you can think of the different lab-generated versions of Cas9 as different models of self-driving cars. Most models are really safe, but they have a top speed of 10 miles per hour.

“They’re safer than the naturally occurring Cas9, but it comes at a big cost: They’re going extremely slowly,” said Bravo. “SuperFi-Cas9 is like a self-driving car that has been engineered to be extremely safe, but it can still go at full speed.”

Physics World Stories podcast, Andrew Glester catches up with two engineers from the UK Atomic Energy Authority to learn more about this latest development. Leah Morgan, a physicist-turned-engineer explains why JET’s recent success is great news for the ITER project – a larger experimental fusion reactor currently under construction in Cadarache, France. Later in the episode, mechanical design engineer Helena Livesey talks about the important role of robotics for accessing equipment within the extreme conditions inside a tokamak device.
