Science National Honor Society’s (SNHS) Big Blue Demo Crew will perform a science show at Castle Hills Elementary Feb. 12 from 5-7 p.m. There will be a total of 16 chemistry demonstrations during each performance, with two shows total. Demo team sponsor and science teacher Dr. Kathleen Holley has worked with the team for 34 years. “The whole idea is to get people excited, but also to teach them about science,” Holley said. “The fact that tap water doesn’t burn, so why is this burning? What does it mean when the water disappears? Where did it go?” The performance will begin with acid-base demos, including a welcome poster and a “bloody” hand experiment. 15 student volunteers will take turns going on the stage to perform their part. Senior Henry Liu is the demo team head and leads the rehear...

There was a moment quite early into my time with Pokémon Pokopia where I sat back, exhaled, and said, “Oh dear, it’s got me.” See, I’ve not been too hot on Pokémon games for a while now, and initial trailers for Pokopia suggested that this probably wouldn’t be changing anytime soon. After spending 90 minutes with both single-player and multiplayer components at Nintendo of Europe's Frankfurt offices, however, I’m convinced: Pokopia — which has Koei Tecmo's Omega Force of Warriors fame heading up development — is going to absolutely gobble up my time. Not only that, but if it's supported by a steady stream of post-launch content (maybe some cool crossover items or events with other Nintendo properties?), it has the potential to be huge. I could tell you that Pokopia is basically Animal Cros...

Physicists' top theory about the nature of the universe may be wrong, a new study of strangely warped light suggests.The new research looked into three leading theories of dark matter, the invisible stuff that makes up most of the universe and provides structure to most galaxies, though we still don't know exactly what it is.For decades, cold dark matter (CDM) has been our leading theory for the universe's invisible scaffolding. It's a neat idea: tiny, slow-moving particles that interact only through gravity. But CDM has its problems. It struggles with explaining galactic anomalies and with describing the strange rotation curves of dwarf galaxies, for example. You may like To further test the nature of dark matter, scientists observe bent starlight from distant galaxies — a process call...

Captured on Nintendo Switch 2 (Docked) If you’re a horror fan and you own a Switch 2, you should play Reanimal. From the moment it pulls you into its bleak, nightmarish world, it’s clear that developer Tarsier Studios is building on everything it learned from the Little Nightmares series while pushing its signature horror sensibilities to unnerving new heights. This is an ambitious evolution of the cinematic horror puzzle-platformer formula the studio helped define with Little Nightmares, one that plays out less linearly in larger 3D spaces, with more varied combat and traversal mechanics and bombastic set pieces. It does so with impeccable sound design, gorgeous lighting, and pitch-perfect atmosphere. Reanimal marks a shift from the Tim Burton-esque macabre of the studio’s earlier titles ...

Pokémon Pokopia can be described as a pocket monster-themed take on Animal Crossing with a hint of Stardew Valley thrown in for good measure. And if you're like me, that alone is probably enough to sell you on the game. However, after getting a chance to play a preview of it for around half an hour, it became immediately clear that the game's coziness levels are off the charts, but it also offers some fun twists on the genre.Co-developed by The Pokémon Company, GAME FREAK and KOEI TECMO, instead of playing as a generic trainer, you take control of a lonely Ditto who wakes up in a cave only to be greeted by Professor Tangrowth, the last surviving inhabitant of what used to be a bustling town. While the professor might look like an extra-large version of the original pokémon with glasses, it...

To me, and I’m sure many others, the Pokémon franchise as a whole has always been “cozy.” Set in a (mostly) idyllic world with cute best friends who are always by your side, how could it not give you warm fuzzy feelings at least occasionally? We’ve had some relaxing Pokémon games over the years, but we’ve never quite had a game that embraced this secondary cozy aesthetic fully into its gameplay–until now, with Pokémon Pokopia. I played the first hour of Pokémon’s first life-sim, and the sheer amount of discovery to be made hooked me. I also played Pokémon Pokopia in multiplayer mode in a more developed world, plus, I learned more straight from the developers. Pokémon Pokopia begins with a Ditto waking up after a long, undefined slumber. It remembers its trainer in its hometown, with the na...

A revitalised Overwatch (formerly Overwatch 2) is bringing players back, propelling the game to most-watched status on streaming service Twitch, and to being one of the most played games on Steam - comfortably above copycat hero-shooter Marvel Rivals. There was even a queue to log in to Overwatch when I played yesterday evening, which is something I've never seen before. Currently there are nearly 100,000 people watching Overwatch streams on Twitch, making it the most viewed game by some way, with nearly 30,000 more viewers than second-place game League of Legends. Meanwhile on Steam, Overwatch peaked at 165,000 players, putting it briefly in the top 10. It's currently 13th, nearly 10 places ahead of genre rival Marvel Rivals, which has trumped Overwatch on Steam for a long time. Note, how...
