- 1Musk 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.
- 2Laser 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.

A physicist has proposed that laser light could transfer energy to a gravitational wave, a concept that would open a new way of interacting with ripples in spacetime. The idea, outlined in recent reporting, suggests beams of light might add energy to gravitational waves as they pass, though it remains a theoretical proposal rather than a demonstrated result. Physicists are weighing whether such an exchange could ever be tested experimentally.

No starship is waiting on a launchpad, but researchers are actively developing the building blocks for interstellar travel. Work under way includes laser-driven light sails, fast precursor probes, fusion propulsion concepts, and missions that would use the sun's gravitational lens as a telescope. Engineers are also designing long-duration spacecraft able to survive decades in flight, laying groundwork for a first voyage to another star.

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.

China marked its 77th National Day with celebrations in Wuhan, where rain failed to deter large crowds gathered along the Yangtze River. Fireworks, laser displays and light shows illuminated the sky over the river, drawing spectators despite wet weather and showcasing the city's festive spirit during the national holiday.

Acupuncture Today examines whether light therapy can improve blood zeta potential, a measure of the electrical charge on red blood cells that influences how they cluster and flow. The article adds to ongoing debate in alternative and integrative medicine circles about whether low-level light or laser treatments can measurably change blood properties and circulation.
