The surface atom density can be utilized to quantitatively explain the reaction process as a function of adsorbate coverage and catalytic reaction rate.

Hurricane Otis turned from mild to monster in record time, and scientists are struggling to figure out how — and why they didn't see it coming. What happened with Otis was just plain nuts, said University of Miami hurricane researcher Brian McNoldy. Still, the storm didn't linger and feed on that, which would be expected in rapid intensification, Brennan said. Numerous studies have shown globally that there are more cases of rapid intensification of hurricanes than there used to be. An official definition of rapid intensification is a gain in strength of 35 mph (56 kph) in 24 hours.

Global monsoon domains. The global land-monsoon area is highly negatively correlated with monsoon precipitation intensity, with a correlation coefficient of -0.87. The results also show that continental area—particularly tropical continental area—determines land-monsoon area, while continent fragmentation determines land-monsoon precipitation intensity. "The modern global land monsoon did not directly originate from the Pangea megamonsoon but emerged after the reassembly of fragmented continents in the Cenozoic." More information: Yongyun Hu et al, Emergence of the modern global monsoon from the Pangaea megamonsoon set by palaeogeography, Nature Geoscience (2023).

Movie stunts come in all shapes and sizes, but no matter the scale, that doesn’t make them any less impressive. Painstakingly crafted scenes that, while they may look staged, were actually filmed for real. ), a decade ago, Vin Diesel and company were still making action the old-fashioned way, stunts and all. Lucky for everyone involved, Tarantino chose a bona fide, real-life stuntwoman—Zoe Bell—to play out the most extreme stunts caught on camera. As such, there are numerous unthinkable stunts from across the seven films that would make an ideal addition to this list—but we had to choose only one.

The fast radio burst is one of the most distant and energetic ever observed. Fast radio bursts, or FRBs, are intense, millisecond-long bursts of radio waves with unknown origins. Many FRBs release super bright radio waves lasting only a few milliseconds at most before disappearing, which makes fast radio bursts difficult to observe. “J-P showed that the (farther) away a fast radio burst is, the more diffuse gas it reveals between the galaxies. Astronomers said they hope that future radio telescopes, currently under construction in South Africa and Australia, will enable the detection of thousands more fast radio bursts at greater distances.

Shalom Israel International Fellowship via FacebookThe family of British 16-year-old Noiya Sharabi confirmed to BBC that she was killed along with her 13-year-old sister, Yahel, and their mother, Lianne, in the Hamas attacks on Israel. The girls and their father, Eli, had been reported missing in the Oct. 7 attack, disappearing from Kibbutz Be’eri, an Israeli settlement in Southern Israel that was targeted in the blitz. The girls’ mother was killed in the attack, and Yahel’s death was confirmed last week. The girls’ father and other relatives remain missing. Noiya and Yahel Sharabi’s mother, British-born Lianne Sharabi moved to Israel to volunteer at a kibbutz before deciding to relocate permanently.
