By using a rare thorium nucleus as a timekeeper, physicists have demonstrated the first working nuclear clock, a device that could lead to even more precise clocks and new ways to search for dark matter.

The San Andreas fault and a neighboring fault in Southern California have reached their highest levels of tectonic stress in 1,000 years, and a rupture at one fault could propagate to the other, researchers found.

The first-ever photos of a Cozumel fox prove that the mysterious island predator is still alive in Mexico but in dire need of conservation, according to researchers.

We think of atomic clocks as the definitive timekeepers. They are famous for being accurate down to the picosecond. Unfortunately, they are still subject to general relativity, so if you put them on a different planet, they will track time slightly faster or slower than on Earth, depending on the planets gravity. In Mars case, an atomic clock on its surface is sitting in a slightly shallower gravity well, meaning that time moves slightly faster there. Therefore, as we begin to expand our technological footprint on the Red Planet, we will need a way to standardize how time is measured there. Dr. Slava Turyshev, a researcher at NASAs Jet Propulsion Laboratory, proposes just such a framework in a new paper available in pre-print on arXiv.

The '90s were a utopia for 3D shooter fanatics. The likes of Doom, Duke Nukem, and Quake were king, and even Star Wars got pulled in with the amazing Dark Forces. As the decade drew to a close, Ritual Entertainment delivered its own mutant-mashing experience, SiN. It's certainly not an all-timer like many of its contemporaries, but SiN had its own, rugged charm. In 2020, remaster maestro Nightdive Studios revealed SiN Reloaded, and now it's finally ready to let you get hands-on with its latest refresh as part of Steam Next Fest.

In Redliner, you can't win with just pure luck. Sure, it helps, but you need to be fast to outsmart your foes in this action-packed Roblox FPS. It throws you into intense battles where every decision matters. If you're searching for Redliner codes, then stop looking. While many Roblox games regularly hand out freebies through redeemable codes, Redliner hasn't revealed any rewards just yet. Even so, that could change in the future, so let's look at what we do know.
