- 1New X-ray technique reveals how quantum materials react to laser pulsesโผScientists develop new X-ray technique to watch quantum materials respond to laser pulses
Researchers have developed a new X-ray technique that allows them to observe, in real time, how quantum materials respond when hit by laser pulses. The method offers a direct window into ultrafast changes in these materials, which could advance research into next-generation electronics and quantum technologies. Details of the advance were announced by the research team behind the technique.
- 2New open-source toolkit decodes and anonymises printer tracking dotsโDEDA โ Tracking Dots Extraction, Decoding and Anonymisation Toolkit
A new open-source tool called DEDA (Tracking Dots Extraction, Decoding and Anonymisation Toolkit) has been released, allowing users to extract, decode and remove the yellow tracking dots that many colour laser printers secretly print on documents. The dots can identify the printer's serial number and print timestamp, raising privacy concerns. The toolkit's release has drawn attention from people interested in document forensics and anonymity.
- 3Pentagon-Style Department Funds Space-Based Solar Power ProjectโThe Department of War Just Funded a Project to Beam Solar Power From Space
The Department of War has funded a project to beam solar power from space, according to a news report. Space-based solar power involves collecting energy in orbit and transmitting it to Earth, typically via microwave or laser beams. Interest in the technology has grown as militaries and energy companies look for reliable, continuous renewable power, since orbiting collectors avoid clouds and nighttime losses. Details about the specific contractor, funding amount and timeline were not provided.
- 4Two Laser Pulses Unlock Never-Before-Seen Electron StatesโผTwo Laser Pulses Unlock Electron States Physicists Had Never Reached Before
Physicists report using two precisely timed laser pulses to drive electrons into quantum states previously unreachable in experiments, according to coverage on SciTechDaily. The technique opens a way to explore and potentially control exotic electronic behavior that standard methods could not access. The research is drawing attention for what it could mean for quantum materials and future technologies.
- 5Laser Gives Scientists Precise Nanoscale Control of PhononsโผLaser Provides Precise Control over Phonons at Nanoscale Level
Researchers report using laser light to precisely control phonons โ quantized vibrations in materials โ at the nanoscale. The advance could enable faster, smaller devices by manipulating heat and sound-like vibrations directly within chips and other nanostructures. It marks a step forward in phononics, a field seeking to use vibrations for information processing and thermal management alongside conventional electronics.
- 6DEDA Toolkit Decodes Printer Tracking Dots for AnonymityโDEDA - Tracking Dots Extraction, Decoding and Anonymisation Toolkit https://github.com/dfd-tud/deda # HackerNews # Tech
DEDA, an open-source toolkit for extracting, decoding and anonymising yellow tracking dots that colour laser printers secretly print on documents, has been released on GitHub by researchers at TU Dresden. The tool lets anyone read the hidden identifying information embedded in printed pages and remove it, raising fresh concerns about printer surveillance and document privacy.
- 7Researchers propose heating plasma first in fusion ignition approachโA novel path to fusion ignition: Heat first, then add fuel
Scientists have outlined a new route to fusion ignition in which the fuel is heated before being added, rather than heating everything together. The approach, described in new research covered by science news services, could offer an alternative to existing laser-based ignition methods as labs worldwide race toward practical fusion energy.
- 8Orlando Science Center to host themed laser shows on Oct. 10โOrlando Science Center returns with themed laser shows on Oct. 10
The Orlando Science Center is bringing back its themed laser shows, scheduled for October 10. The event combines music with laser light displays at the Florida science museum. Details on the lineup and ticketing have not been widely reported, but the return of the shows is drawing local attention ahead of the date.
