Affordable, room-temperature maser created using LED technology

With the ability to detect and amplify extremely weak electromagnetic signals without adding additional noise, masers have many potential uses, including the production of more sensitive magnetic resonance body scanners, such as those used in airports.

Despite their discovery in the 1950s, there has been little development of the technology since then due to the complex and expensive conditions required to make them—masers are only able to be produced in very cold conditions, while also within a vacuum and a high magnetic field.

Northumbria’s Dr. Juna Sathian is one of the U.K.’s leading experts in maser technology and has previously worked with colleagues at Imperial College London and University College London to develop a room-temperature maser which works using laser light. However, this method is expensive and difficult to replicate in everyday applications.

Gold Melody IAB Exploits Exposed ASP.NET Machine Keys for Unauthorized Access to Targets

Some of the other tools downloaded onto the systems include an ELF binary named atm from an external server (“195.123.240[.]233:443”) and a Golang port scanner called TXPortMap to map out the internal network and identify potential exploitation targets.

“TGR-CRI-0045 uses a simplistic approach to ViewState exploitation, loading a single, stateless assembly directly,” the researchers noted. “Each command execution requires re-exploitation and re-uploading the assembly (e.g., running the file upload assembly multiple times).”

“Exploiting ASP.NET View State deserialization vulnerabilities via exposed Machine Keys allows minimal on-disk presence and enables long-term access. The group’s opportunistic targeting and ongoing tool development highlight the need for organizations to prioritize identifying and remediating compromised Machine Keys.”

Rethinking the Anomalous Hall Effect: A Symmetry Revolution

A new symmetry-breaking scenario provides a comprehensive description of magnetic behavior associated with the anomalous Hall effect.

In 1879 Edwin Hall discovered that a flat conductor carrying current, when placed in a magnetic field, will develop a transverse voltage caused by the deflection of charge carriers. Two years later he discovered that the same effect arises in ferromagnets even without an applied magnetic field. Dubbed the anomalous Hall effect (AHE), that phenomenon, alongside the ordinary Hall effect, not only catalyzed the rise of semiconductor physics and solid-state electronics but also laid the groundwork for a revolutionary convergence of topology and condensed-matter physics a century after Hall’s discoveries. Recent experiments, however, have uncovered behavior that cannot be explained with current theories for the AHE.

Space-based experiments show wax-filled heat sinks keep electronics cooler for longer

An interdisciplinary research team including mechanical science and engineering professor Mickey Clemon from the Grainger College of Engineering at the University of Illinois Urbana-Champaign is investigating cooling methods for heat sinks by performing experiments onboard a satellite currently orbiting Earth.

“University-sponsored satellites have a very low success rate of making it into space, so we’re very happy that we made it into space and that our system works,” Clemon said.

The team has published the recent findings from their ongoing study, “Investigating the performance of a heat sink for satellite avionics : From ground-level testing to space-like conditions,” in the International Journal of Heat and Mass Transfer.

Displays, imaging and sensing: New blue fluorophore breaks efficiency records in both solids and solutions

A new blue fluorescent molecule set new top emission efficiencies in both solid and liquid states, according to a University of Michigan-led study that could pave the way for applications in technology and medicine.

Able to absorb light and emit it at lower energy levels, called fluorophores glow in OLED displays and help doctors and scientists figure out what’s happening in cells and tissues. They need to be solid in displays and many sensing applications, but liquids are typically preferred for biological uses. Most fluorophores don’t work well in both forms, but this one does.

The study, “Elucidating the molecular structural origin of efficient emission across solid and solution phases of single benzene fluorophores,” is published in the journal Nature Communications.

‘Unlike conventional electronics’: New liquid metal-infused circuit boards can self-heal and work after taking heavy damage

New recyclable electronics could be critical to curbing e-waste, scientists argue, especially because these circuit boards can be repaired or reconfigured by simply applying heat.

New technique tracks blood sugar with light

Diabetes is a very prevalent disease that, unfortunately, still has no treatment. People with diabetes need to monitor their blood glucose levels (BGLs) regularly and administer insulin to keep them in check. In almost all cases, BGL measurements involve drawing blood from a fingertip through a finger prick. Since this procedure is painful, less invasive alternatives that leverage modern electronics are being actively researched worldwide.
