- 1DEDA Toolkit Exposes Hidden Printer Tracking Dots●DEDA – Tracking Dots Extraction, Decoding and Anonymisation Toolkit
A new open-source toolkit called DEDA (Tracking Dots Extraction, Decoding and Anonymisation Toolkit) has been released by researchers at TU Dresden. It extracts, decodes and removes the yellow tracking dots that many colour laser printers secretly print on documents, which can identify the printer's serial number and print date. The release renews debate about printer privacy and document anonymisation.
- 2Musk says Lidar is why Tesla Robotaxi avoids night driving●Musk explains why Tesla Robotaxi isn't running at night, and Lidar is the answer
Elon Musk has explained why Tesla's Robotaxi service is not operating at night, citing the absence of Lidar in Tesla's sensor suite. Without the laser-based technology used by many rivals, the vehicles reportedly cannot safely handle low-light conditions. The explanation is drawing attention because Musk has long dismissed Lidar as unnecessary, making the admission a notable shift in the debate over autonomous driving sensor strategies.
- 3Two Laser Pulses Unlock Never-Before-Seen Electron States▼Two 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.
- 4Laser Gives Scientists Precise Nanoscale Control of Phonons●Laser Provides Precise Control over Phonons at Nanoscale Level
Researchers report using laser light to precisely control phonons — quantized vibrations in materials — 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.
