Scientists Have Identified the Origin of an Extraordinarily Powerful Outer Space Radio Wave


The Earth is constantly receiving space signals that contain vital information about extremely energetic phenomena. Among the most peculiar are brief pulses of extremely high-energy radio waves, known as fast radio bursts (FRB). Astronomers compare them to a powerful lighthouse that shines for milliseconds in the middle of a rough, distant sea. Detecting one of these signals is an achievement in itself, but identifying its origin and understanding the nature of its source remains one of the great challenges of science.

That is why recent research led by Northwestern University in the United States has captured the attention of the astronomical community. The team not only detected one of the brightest FRBs ever recorded, but also traced its origin with unprecedented precision.

The pulse, identified as RBFLOAT, arrived in March 2025, lasted just a few milliseconds, and released as much energy as the sun produces in four days. Thanks to a new method of analysis, the researchers located its origin in an arm of a spiral galaxy located 130 million light-years away, in the direction of the constellation Ursa Major. The research was published in the journal The Astrophysical Journal Letters.

The CHIME radio telescope in Canada, one of the world’s leading FRB observatories, and a subnetwork of smaller stations called Outriggers detected the anomalous outburst. CHIME characterized the signal, while the Outriggers triangulated it to a narrow region of space. Optical and X-ray telescopes then provided complementary data. The team achieved a precision of 13 parsecs, equivalent to 42 light-years, within the galaxy NGC 4141.

Astronomers had previously pinpointed other FRBs, but in those cases the signals were repeated, which made the analysis easier. “RBFLOAT was the first non-repeating source localized to such precision,” said Sunil Simha, coauthor of the study, in a university statement. “These are much harder to locate. Thus, even detecting RBFLOAT is proof of concept that CHIME is indeed capable of detecting such events and building a statistically interesting sample of FRBs.”

What Caused the RBFLOAT?

Scientists are still not sure what causes RBFs, but they have some ideas. Because of the enormous energy they release and the brevity of the phenomenon, it is likely that they originate from extreme cosmic events, such as neutron star mergers, magnetars, or pulsars.

In the case of RBFLOAT, the data indicate that it is located in a star-forming region with really massive stars. The triangulation places the signal in a galactic arm where new stars are also being born. This suggests that it could be a magnetar, a subclass of neutron star with a magnetic field billions of times stronger than that of the Earth.

The experience with RBFLOAT will allow the team to apply the same triangulation technique to future signals. The authors estimate that they could achieve about 200 accurate RBF detections per year with just the signals CHIME captures.

“For years, we’ve known FRBs occur all over the sky, but pinning them down has been painstakingly slow. Now, we can routinely tie them to specific galaxies, even down to neighborhoods within those galaxies,” said Yuxin Dong, another member of the team.

Cyber body ISC2 signs on as UK software security ambassador | Computer Weekly


ISC2, the non-profit cyber professional membership association, has joined the UK government’s recently launched Software Security Ambassador Scheme as an expert adviser.

Set up at the beginning of the year by the National Cyber Security Centre (NCSC) and the Department for Science, Innovation and Technology (DSIT), the scheme forms part of a wider £210m commitment by Westminster to remodel approaches to public sector cyber resilience from the ground up, acknowledging that previous approaches to the issue have basically gone nowhere and that previously set targets for resilience are unachievable.

It is designed to incentivise organisations to pay more attention to the security of software products, and supports the wider adoption of the Software Security Code of Practice, a set of voluntary principles defining what secure software looks like.

ISC2 joins a number of tech suppliers, including Cisco, Palo Alto Networks and Sage; consultancies and service providers including Accenture and NCC Group; and financial services firms including Lloyds Banking Group and Santander. Fellow cyber association ISACA is also involved.

“Promoting secure software practices that strengthen the resilience of systems underpinning the economy, public services and national infrastructure is central to ISC2’s mission,” said ISC2’s executive vice-president for advocacy and strategic engagement, Tara Wisniewski.

“The code moves software security beyond narrow compliance and elevates it to a board-level resilience priority. As supply chain attacks continue to grow in scale and impact, a shared baseline is essential and through our global community and expertise, ISC2 is committed to helping professionals build the skills needed to put secure-by-design principles into practice,” she said.

Software vulns a huge barrier to resilience

A study of wider supply chain risks conducted last year by ISC2 found that a little over half of organisations worldwide reported that vulnerabilities in their software suppliers’ products represented the most disruptive cyber security threat to their overall supply chain.

And the World Economic Forum’s (WEF’s) Global Cybersecurity Outlook report, published on 12 January, revealed that third-party and supply chain vulnerabilities were seen as a huge barrier to building cyber resilience by C-suite executives.

A total of 65% of respondents to the WEF’s annual poll flagged such flaws as the greatest challenge their organisation faced on its pathway to resilience, compared to 54% at the beginning of 2025. This outpaced factors such as the evolving threat landscape and emerging AI technology, use of legacy IT systems, regulatory compliance and governance, and cyber skills shortages.

Pressed on the top supply chain cyber risks, respondents were most concerned about their ability to assure the integrity of software and other IT services, ahead of a lack of visibility into their supplier’s supply chains and overdependence on critical third-party suppliers.

The UK’s Code of Practice seeks to answer this challenge by establishing expectations and best practices for tech providers and any other organisations that either develop, sell or buy software products. It covers aspects such as secure design and development, the security of build environments, deployment and ongoing upkeep, and transparent communication with customers and users.

As part of its role as an ambassador, ISC2 will assist in developing and improving the Code of Practice, while championing it by embedding its guiding principles into its own cyber education and professional development services – the organisation boasts 10,000 UK members and associates. 

It will also help to drive adoption of the Code of Practice through various awareness campaigns, incorporating it into its certifications, training and guidance, engaging with industry stakeholders and members to encourage implementation, and incorporating its provisions into its work with its own commercial suppliers.

Asus Made a Split Keyboard for Gamers—and Spared No Expense

Asus Made a Split Keyboard for Gamers—and Spared No Expense


The wheel on the left side has options to adjust actuation distance, rapid-trigger sensitivity, and RGB brightness. You can also adjust volume and media playback, and turn it into a scroll wheel. The LED matrix below it is designed to display adjustments to actuation distance but feels a bit awkward: Each 0.1 mm of adjustment fills its own bar, and it only uses the bottom nine bars, so the screen will roll over four times when adjusting (the top three bars, with dots next to them, illuminate to show how many times the screen has rolled over during the adjustment). The saving grace of this is that, when adjusting the actuation distance, you can press down any switch to see a visualization of how far you’re pressing it, then tweak the actuation distance to match.

Alongside all of this, the Falcata (and, by extension, the Falchion) now has an aftermarket switch option: TTC Gold magnetic switches. While this is still only two switches, it’s an improvement over the singular switch option of most Hall effect keyboards.

The internal assembly of this keyboard is straightforward yet interesting. Instead of a standard tray mount, where the PCB and plate bolt directly into the bottom half of the shell, the Falcata is more comparable to a bottom-mount. The PCB screws into the plate from underneath, and the plate is screwed onto the bottom half of the case along the edges. While the difference between the two mounting methods is minimal, it does improve typing experience by eliminating the “dead zones” caused by a post in the middle of the keyboard, along with slightly isolating typing from the case (which creates fewer vibrations when typing).

The top and bottom halves can easily be split apart by removing the screws on the plate (no breakable plastic clips here!), but on the left half, four cables connect the top and bottom halves of the keyboard, all of which need to be disconnected before fully separating the two sections. Once this is done, the internal silicone sound-dampening can easily be removed. The foam dampening, however, was adhered strongly enough that removing it left chunks of foam stuck to the PCB, making it impossible to readhere without using new adhesive. This wasn’t a huge issue, since the foam could simply be placed into the keyboard, but it is still frustrating to see when most manufacturers have figured this out.

These Sub-$300 Hearing Aids From Lizn Have a Painful Fit

These Sub-0 Hearing Aids From Lizn Have a Painful Fit


Don’t call them hearing aids. They’re hearpieces, intended as a blurring of the lines between hearing aid and earbuds—or “earpieces” in the parlance of Lizn, a Danish operation.

The company was founded in 2015, and it haltingly developed its launch product through the 2010s, only to scrap it in 2020 when, according to Lizn’s history page, the hearing aid/earbud combo idea didn’t work out. But the company is seemingly nothing if not persistent, and four years later, a new Lizn was born. The revamped Hearpieces finally made it to US shores in the last couple of weeks.

Lizn Hearpieces are the company’s only product, and their inspiration from the pro audio world is instantly palpable. Out of the box, these look nothing like any other hearing aids on the market, with a bulbous design that, while self-contained within the ear, is far from unobtrusive—particularly if you opt for the graphite or ruby red color scheme. (I received the relatively innocuous sand-hued devices.)

At 4.58 grams per bud, they’re as heavy as they look; within the in-the-ear space, few other models are more weighty, including the Kingwell Melodia and Apple AirPods Pro 3. The units come with four sets of ear tips in different sizes; the default mediums worked well for me.

The bigger issue isn’t how the tip of the device fits into your ear, though; it’s how the rest of the unit does. Lizn Hearpieces need to be delicately twisted into the ear canal so that one edge of the unit fits snugly behind the tragus, filling the concha. My ears may be tighter than others, but I found this no easy feat, as the device is so large that I really had to work at it to wedge it into place. As you might have guessed, over time, this became rather painful, especially because the unit has no hardware controls. All functions are performed by various combinations of taps on the outside of either of the Hearpieces, and the more I smacked the side of my head, the more uncomfortable things got.
