- 1Debate over NAZA film's Gaza allegations and journalistic standards▼NAZA’s claims about IDF conduct in Gaza are grave. So are the film’s journalistic flaws
The Times of Israel highlights controversy around NAZA, a documentary making serious allegations about the conduct of Israeli soldiers in Gaza. Commentary acknowledges the gravity of the claims while also pointing to significant journalistic shortcomings in the film's sourcing and methods, fueling arguments on both sides about its credibility and the underlying questions it raises.

Researchers have developed the world's most accurate atomic clock, an advance reported by Phys.org. The new clock pushes precision beyond previous devices, improving timekeeping so finely that it could lose essentially no time over the age of the universe. Such clocks underpin GPS, telecommunications and fundamental physics tests, including measuring gravity's effect on time and searching for dark matter.

Physicists report new evidence that gravity can collapse the dimensions of space, supporting the idea that gravity is holographic — that the universe's three-dimensional structure may be encoded on a lower-dimensional surface. Researchers stress the implications are not yet understood, and what this means for the nature of reality remains an open question driving discussion among cosmologists and science commentators.
- 4Spacecraft hunting for life on icy moons swings past Earth●Why a spacecraft exploring moons where life may thrive is zipping by Earth
A spacecraft built to explore icy moons where life could exist is flying close by Earth, using the planet's gravity to adjust its course. The maneuver is part of a long journey toward the outer solar system, where scientists hope to study oceans beneath the moons' surfaces. The flyby has drawn attention as a milestone in the search for conditions suitable for life beyond our planet.

ESA's Juice spacecraft is scheduled to fly past Earth tomorrow as part of another gravity assist manoeuvre on its journey to Jupiter. The flyby has drawn attention among space enthusiasts, with one contributor involved in planning camera shots for the manoeuvre noting that new imaging techniques are being tried during the pass.

A Quanta Magazine article explaining the holographic principle in physics is being discussed on Hacker News. The idea is that gravity in a volume of space can be described by information encoded on that volume's boundary, as in the AdS/CFT correspondence, suggesting three-dimensional reality may emerge from lower-dimensional information. Commenters on the post are debating what this implies about the fundamental nature of space, time and whether reality is a projection.
