Physicists have reported the first working nuclear clocks, using an energy transition in the atomic nucleus rather than electron orbitals, marking a milestone after decades of attempts. Work on the thorium-229 transition, first driven with a laser in 2024, has opened a competition among labs to build clocks more stable than today's best atomic timekeepers. Researchers say nuclear clocks could probe whether fundamental constants of nature change over time, and labs worldwide are now racing to push the precision further.
- 3Glass Beads Entangled Using Laser Optical TweezersโผThis article makes quantum entanglement research with a glass bead and a light beam seem magical, with its optical tweez
Researchers have entangled vibrating glass beads using optical tweezers, kicking the beads into entanglement by shifting the frequency of a laser beam. The technique uses focused light to hold and manipulate tiny objects, allowing precise quantum control. Readers are sharing the study and remarking on how the experiment makes quantum entanglement research look almost magical, with ordinary glass and light producing distinctly quantum behaviour.

The JMGO N1S Ultimate 4K triple-laser projector has been cut to $1,299 in an Amazon Prime Day deal, a 54% discount saving buyers $1,500. The projector features Google TV and a built-in gimbal stand. Tech writers are highlighting the deal as one of the more eye-catching projector discounts of the Prime Day sale, given the size of the price cut on a premium 4K laser model.
- 5MIT Study Finds a Neutrino Laser May Be ImpossibleโผMIT Study Reveals Why a Neutrino Laser May Be Impossible
A new MIT study examines the feasibility of a neutrino laser, a hypothetical device that would emit neutrinos coherently like an optical laser emits light. The research concludes that fundamental physical constraints likely make such a device impossible to build. The findings are drawing attention in physics communities interested in neutrino behavior and extreme-state matter.

Quantum technology firm Infleqtion, Honeywell and the University of California, Santa Barbara have jointly developed a chip-scale optical cavity, a component used to stabilise lasers in quantum and photonic systems. Shrinking such cavities onto a chip could make quantum devices smaller, cheaper and easier to deploy at scale, and the collaboration draws on Infleqtion's quantum expertise, Honeywell's hardware capabilities and UCSB's photonics research.
- 12Pentagon-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.
- 13Two Laser Pulses Unlock Never-Before-Seen Electron StatesโTwo 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.
