We demonstrate submicrometer focusing of isolated attosecond pulses in the extreme ultraviolet region using a custom ellipsoidal mirror. The obtained focal spot sizes were verified using knife-edge measurements with a sharp silicon edge, confirming reproducible dimensions down to 0.46 μm × 0.36 μm (full width at half maximum), demonstrating near-diffraction-limited focusing performance. Focusing a 1.1-GW tabletop isolated attosecond pulse source yields a peak intensity of 3 × 1015 W/cm2, and a realistic pathway toward 1016 W/cm2 is obtained by optimizing the beamline throughput. These results establish a practical route toward attosecond nonlinear optics in both gas and solid phases, driven by intense extreme ultraviolet fields.

Twisted atomic layers slide spontaneously at room temperature in simulations
Researchers revealed an ultralow-barrier collective sliding mechanism mediated by domain walls, as well as defect-induced pinning of the sliding motion. They found that twisted bilayer MoS₂ moiré superlattices can undergo spontaneous long-range interlayer sliding at room temperature, while a sulfur-vacancy concentration of only about 0.1% can turn the motion into localized oscillations.
The study was conducted by a collaborative team involving professors Zhang Jin and Shi Xinghua from the National Center for Nanoscience and Technology (NCNST) of the Chinese Academy of Sciences (CAS) and professor MENG Sheng from the Institute of Physics (IOP) of CAS.
The findings were published in the Journal of the American Chemical Society.
Intravenous Thrombolysis for Acute Ischemic Stroke
In the past 5 years, substantial changes have been made in the use of intravenous thrombolysis (IVT) in patients with acute ischemic stroke. Integrating IVT with endovascular thrombectomy, which improves outcomes in patients with stroke due to large cerebral vessel occlusion, has been a particular challenge. This review discusses the underlying vascular targets for IVT and thrombectomy, the increasing use of tenecteplase instead of alteplase, broadening indications for the use of IVT, and ancillary drugs and dosing methods that may augment the success of IVT.
Why Nokia Put A Spinning HARD DRIVE Inside A Phone… 😳#shorts
Back in 2005, high-capacity flash memory (SD/MMC cards) was outrageously expensive per gigabyte. So how did Nokia build a phone that could carry thousands of…
They Turned A Floppy Disk Into A 10Gbps SSD 🤯#shorts
Back in the 1990s, standard 3.5-inch floppy disks topped out at a mere 1.44 megabytes of data not even enough to store a single high-resolution smartphone image today. The Hagibis Retro Floppy Disk SSD Enclosure takes that legendary retro silhouette and reimagines it for modern workflow speeds. Crafted from premium alloy and featuring a functional spring-loaded metal shutter with customizable retro write-in labels, it houses an ultra-fast M.2 NVMe SSD inside. Connecting via USB-C at transfer speeds up to 10Gbps, it blends tactile nostalgia with high-performance storage. Today on DiyTech, we check out one of the coolest retro desk tech accessories ever made. Did you ever use real floppy disks back in the day?

Google Takes Over Wyoming Data Center That Crusoe Had Pitched
Alphabet Inc.’s Google has bought out Crusoe’s data center site in southeast Wyoming, opting to take on the project itself after the AI computing upstart failed to lock in customers.
What Is Computer Science About? Or, the Most Dangerous Bug
Computer science has a bug. No compiler will ever catch it.
It might be the most dangerous one we’ve ever shipped. And with #AI, we’re about to ship it everywhere.
It starts with a deceptively simple question: what is #ComputerScience actually about?
If you said “computers,” you’re in good company.
I’d argue you’re also wrong.
The answer, and the bug, are in this article. It involves a telescope and your neighbor’s window.
Read it. Then tell me where I’m wrong.
