Fundamental spatial limits of all-optical magnetization switching
Magnetization can be switched with a single laser pulse. However, it is not known whether the underlying microscopic process is scalable to the nanometer length scale, a prerequisite for making this technology competitive for future data storage appl.....»»
Researchers develop technology to mass produce quantum dot lasers for optical communications
South Korean researchers have successfully developed technology to mass-produce quantum dot lasers, widely used in data centers and quantum communications. This breakthrough paves the way for reducing the production cost of semiconductor lasers to on.....»»
Apple shares photos as first customers outside the US buy Vision Pro
The first customers outside the US have been able to buy Vision Pro this morning, and Apple has shared photos from stores in three countries. The photos show the demo zones set up for customers to try the spatial computer, as well as some of those.....»»

Study projects loss of brown macroalgae and seagrasses with global environmental change
Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role of seaweeds and seagrasses in coastal ecosystems, and.....»»
Largest Croatian hospital under cyberattack
The University Hospital Centre Zagreb (KBC Zagreb) is under cyberattack that started on Wednesday night, the Croatian Radiotelevision has reported. Because of the attack, the hospital has shut down its information system and will be switching parts o.....»»
Learning from Great Tits" Urban Adaptability
One of Europe’s most common birds, the great tit, show an amazing adaptability to human-made habitats. There seem no limits for this species when it comes inventing new ways of acquiring food from people.....»»
Threads fediverse integration enhanced, but still some key limits
Meta has just made a significant enhancement to its Threads fediverse integration – though there are still some key limits to what is possible in the app … more….....»»
Time-compression in electron microscopy: Terahertz light controls and characterizes electrons in space and time
Scientists at the University of Konstanz in Germany have advanced ultrafast electron microscopy to unprecedented time resolution. Reporting in Science Advances, the research team presents a method for the all-optical control, compression, and charact.....»»
World record 402 Tb/s transmission in a standard commercially available optical fiber
An international joint research team led by the Photonic Network Laboratory of Japan's National Institute of Information and Communications Technology (NICT) has demonstrated a record-breaking aggregate optical transmission bandwidth of 37.6 THz to e.....»»
Stress testing pension funds—researchers present technique based on hidden Markov regime switching model
"We wanted to investigate how second pillar pension funds react to financial crises and how to protect them from the crises," says Kaunas University of Technology (KTU) professor Dr. Audrius Kabašinskas, who, together with his team, discovered a way.....»»
Scientists discover genetic "off switch" in legume plants that limits biological ability to source nutrients
A genetic "off switch" that shuts down the process in which legume plants convert atmospheric nitrogen into nutrients has been identified for the first time by a team of international scientists......»»
Scientists unveil vacancy-assisted fatigue damage mechanism at small scales
Classical theories of fatigue damage in bulk metals have been extensively studied, but little is known about the fundamental fatigue mechanisms at submicron and nanometer scales, where dislocation pattern formation is completely inhibited......»»
A model of Collaborative Ethics to guide translational research from fundamental discoveries to real-world applications
In sciences, disruptive research that is breaking new ground often raises new and not-yet-explored ethical questions. Although new scientific breakthroughs can have the power to change how we understand and live in the world, the ethical implications.....»»
Robots steal jobs from unions—study shows decline in unionizations
Collective bargaining is a fundamental pillar of the European social model. In Italy, over the decades, unions have ensured wage increases commensurate with productivity growth and a gradual improvement in working conditions. Today, however, they are.....»»
Researchers develop polymer fibers that can facilitate controlled, local drug delivery
Medical products such as ointments or syringes reach their limits when it comes to delivering medication locally—and above all in a controlled manner over a longer period of time. Empa researchers are therefore developing polymer fibers that can de.....»»
How "sticky" is dense nuclear matter?
Colliding heavy atomic nuclei together creates a fluidlike soup of visible matter's fundamental building blocks, quarks and gluons. This soup has very low viscosity—a measure of its "stickiness," or resistance to flow......»»
Developers can now create larger apps and games for iOS 18 and tvOS 18
Some users may not be familiar with this, but Apple sets size limits for iOS and tvOS apps, so that a single app can’t take up too much space. However, as apps and especially games get more advanced, they also get larger and require more storage. B.....»»
Microsoft removes documentation for switching to a local account in Windows 11
But most Microsoft account sign-in workarounds for Windows 11 continue to work. Enlarge / A PC running Windows 11. (credit: Microsoft) One of Windows 11's more contentious changes is that, by default, both the Home and P.....»»
3D maps of diseased tissues at subcellular precision
Researchers in the Systems Biology Lab of Professor Nikolaus Rajewsky, at the Max Delbrück Center, have developed a spatial transcriptomics platform, called Open-ST, that enables scientists to reconstruct gene expression in cells within a tissue in.....»»
Ice recon: Satellite navigation breakthrough in mapping sea ice thickness
The polar regions are critical to understanding climate change due to their significant impact on global weather patterns and sea levels. Traditional methods of measuring sea ice thickness face challenges such as high costs and limited spatial covera.....»»
