An asteroid approximately the size of the one that finished off the dinosaurs collided with the surface of Mars, causing a massive tsunami that changed hundreds of thousands of square miles.

The new study describes the great tidal waves as megatsunamis, with previous research attributing two megatsunami events triggered by two asteroid impacts that happened approximately 3.4 billion years ago. In an older study, researchers pointed to a 75-mile-wide crater called the Lomonosov Crater for the location of an asteroid impact that caused one of these massive waves.

Scientists estimated that the asteroid that created the Lomonosov Crater created a tsunami that covered 309,000 square miles of land. Newer research is indicating that a second megatsunami that covered 386,000 miles of land was caused by an asteroid that carved a 69-mile-wide Pohl Crater. The massive diameter of the Pohl Crater leads researchers to believe that the asteroid that created it was about the same size as the 6-mile-wide asteroid that wiped out the dinosaurs.

The US Air Force has unveiled a new stealth bomber that is being described as the "most advanced military aircraft ever built".

The United States Air Force has unveiled its first new bomber in more than 30 years, the B-21 Raider, developed by Northrop Grumman, is a stealth bomber that was recently showcased at an invite-only event. An Air Force spokesperson informed Air Force Magazine of the unveiling and said that the aircraft isn't expected to take to the skies until next year.

Notably, Northrop Grumman will be conducting its own unveiling of the aircraft on December 2, and the event was streamed to YouTube. During the presentation, Northrop Grumman claimed that the B-21 Raider is the "world's first sixth-generation aircraft", putting it far beyond any other current aircraft in terms of capabilities than what is known to the public.

NVIDIA has just announced that its Ada Lovelace GPU-exclusive DLSS 3 upscaling technology is coming to some of December's biggest games, joining the list of 14 games that already rock DLSS 3 support.

DLSS 3 only dropped in October 2022 with the release of NVIDIA's flagship GeForce RTX 4090 "Ada Lovelace" graphics card, with the fun continuing last month with the second-fastest Ada Lovelace release in the GeForce RTX 4080 16GB graphics card. But now... DLSS 3 is being added to five new games in December 2022.

We can expect DLSS 3 updates for Need for Speed Unbound, Warhammer 40,000 Darktide, Portal with RTX, Jurassic World Evolution 2 and Witcher 3: Wild Hunt's upcoming "Next-Gen Update". I'm sure that the release of Portal with RTX is going to be one of the most-hyped DLSS 3-powered titles.

GALAX is teasing some more custom GeForce RTX 40 series "SG" graphics cards themed in white, which we should start hearing -- and seeing -- more of very soon.

The official GALAX Japan Twitter account tweeted out the tease, where we should expect the new GeForce RTX 4090, GeForce RTX 4080 -- and probably even the GeForce RTX 4070 Ti -- in white, under their "SG" family of cards, better known as Serious Gaming.

GALAX's upcoming GeForce RTX 40 series "SG" white-themed graphics cards aren't new, they were unveiled recently but never released into the market just yet. GALAX has its other GeForce RTX 40 series "EX" and "HOF" with the HOF (Hall of Fame) graphics cards already breaking world records now that EVGA has left the graphics card business.

AMD is celebrating its Holiday Deals on discounted Ryzen 7000 series "Zen 4" processors, with some new retail desktop CPU packaging... check it out:

AMD's new Ryzen 7000 series "Zen 4" processors are still available on the cheap, just like they were last week and over the weekend with the one-two-punch discounts of the Black Friday and Cyber Monday deals, but now AMD is keeping the Zen 4 chips cheap.. with some refreshed CPU packaging.

The new packaging sports an outline on AMD's own logo, which looks better from the outside... but other than that, there's not much new here. But the bigger deal here is that AMD's discounted pricing on their fleet of Ryzen 7000 series "Zen 4" processors seems permanent, and not just for the Black Friday and Cyber Monday discounts, which is awesome for consumers.

In a few hours' time the release of The Callisto Protocol takes place, with the developer taking to Twitter to announce the "Max" and "Ultra" PC requirements for the game.

The Callisto Protocol requires 8GB of RAM and 75GB of storage at a minimum, with the developer recommending gamers use an SSD -- it's 2022, you really should be -- while you'll need Windows 10 or Windows 11 at a minimum, too.

Moving onto the CPU requirements, The Callisto Protocol developer recommends an Intel Core i5-8400 or AMD Ryzen 5 2600 processor for the minimum PC requirements, while the recommended PC requirements bump the CPU recommendation up to an Intel Core i7-8700 or AMD Ryzen 5 3600 processor. The recommended PC specs for The Callisto Protocol also get bumped from 8GB of RAM, to 16GB of RAM, too.

PCI-SIG has been direct in its statement to partners that provides the required technical information for the proper design of its 12VHPWR power connector, which you'd think would be cemented in stone at its inception. In a way, PCI-SIG is clearing itself of any wrongdoing by users who don't connect the 12VHPWR 16-pin power connector to their GeForce RTX 40 series GPU.

The statement from PCI-SIG in question is from an on-going lawsuit against NVIDIA "Genova v NVIDIA Corporation" which claims that the use of the 16-pin power connector on NVIDIA's suite of GeForce RTX 40 series GPUs pose a serious "electrical and fire hazard".
