A new study published in AGU Advances highlights the discovery.

Scientists previously believed that any flowing water on the surface of Mars evaporated around 3 billion years ago. Now, with the data gathered from the Mars Reconnaissance Orbiter (MRO) over the last fifteen years, scientists believe water was flowing as recently as between 2 and 2.5 billion years ago.

Using the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument aboard the MRO allowed the researchers to find chloride salts mineral evidence of water left over after it would have evaporated. The Context Camera and High-Resolution Imaging Science Experiment (HiRISE) camera aboard the MRO allow the Mars terrain to be mapped, using the number of craters in an area to determine the age of a given surface. Analysis of the terrain allowed the team to date the salt deposits and tell when water was flowing in different areas.

Aboard the module is the Light Microscopy Module (LMM), and material from the InSPACE-4 and cell signaling in microgravity experiments.

The SpaceX Dragon spacecraft arrived at the International Space Station (ISS) on December 22nd, 2021, with a scheduled for undocking on January 22nd, 2021, followed by a splashdown on Earth the next day. The mission, CRS-24, was a resupply mission to the ISS and has brought back with it some scientific hardware and material from various experiments.

The Light Microscopy Module (LMM) is a powerful light imaging microscope launched to the ISS in 2009, which is now being retired, returning to Earth aboard the Dragon craft. It contributed to many experiments, which you can read about on NASA's website.

Researchers from the University of Stirling have published the new study in the Journal of Evolutionary Biology.

The researchers found that animals closer to the nuclear reactor in Chernobyl had more genetic mutations than those located further away. Analyzing freshwater crustaceans, Daphnia pulex, they found higher doses of radiation created greater genetic diversity in their populations.

"Normally you have to wait for generations to see the effect of the environment on mutations, and most mutant animals are pretty damaged so don't live long. By sequencing non-coding DNA, bits of genetic code that don't actually affect the form or function of the organism, we were able to uncover these mutations," said Dr. Stuart Auld of Stirling's Faculty of Natural Sciences.

A new study using artificial intelligence has revealed the potential for more meteorite discoveries.

Almost two-thirds of all meteorites on Earth are found in Antarctica, where their dark color allows them to stick out amidst the snowy, barren landscape. Over time, they can become buried by snow, burying them in ice sheets that can help preserve them on land, or may flow toward the ocean and dump them in the water.

Some meteorites become exposed in areas of blue ice if factors such as wind are optimal, and most meteorites recovered in Antarctica have been found in these areas. This new study uses artificial intelligence to analyze the surface of Antarctica uses optical, thermal, and radar data to determine likely zones in which to find meteorites.

The remains of the rocket are from a Falcon 9 that launched in February 2015.

The rocket launched to deliver a NASA satellite, the Deep Space Climate Observatory (DSCOVR), into orbit. Instead of returning to Earth, the rocket's second stage had flown far enough away that it entered into a chaotic orbit. It is estimated that it will crash into the far side of the moon on March 4th, 2022.

"We know the mass of an empty Falcon 9 booster [about 4 tons] and that it will hit at 2.58 km/s [5,700 mph, or 9,290 kph]; the known momentum and energy of the object making the crater ought to help in calibrating the crater size vs. energy function," said astronomer Bill Gray, who calculated the space junk's trajectory.

Intel's new Arc Alchemist discrete GPUs have been spotted again, with the new DG2-384 GPU spotted with 6 memory modules labeled as "Samsung K4ZAF325BM-HC16".

We should expect each of these GDDR6 memory modules to be 2GB a pop, clocked at 16Gbps -- which means with the 384 EU variant of the Arc Alchemist packing 12GB of GDDR6 @ 16Gbps on a 192-bit memory bus -- resulting in around 384GB/sec of memory bandwidth.

This is the second Arc Alchemist GPU, aka "SKU2" or the 384 EU variant -- packing 12GB GDDR6 @ 16Gbps -- while the flagship "SKU1" or the 512 EU variant, packs 16GB of GDDR6 (8 x 2GB modules) at 16Gbps on a 256-bit memory bus for up to 512GB/sec of memory bandwidth.

Facebook, I mean Horizons, I mean LifeLog, I mean Meta have announced that the social networking -- and VR giant -- is putting the finishing touches on the world's fastest AI supercomputer.

The new AI Research SuperCluster (RSC) is already being built and expected to be online by mid-2022, where it is already being used to train huge models in natural language processing (NLP) and computer vision for research -- Meta's aim with RSC -- is that it will one-day train models with trillions and trillions of parameters.

RSC will help super-fuel Meta's AI researchers that will be capable of being fed trillions of examples, where it will use AI to work through hundreds of languages across the planet, seamlessly analyze text, images, and videos together, develop new augmented reality (AR) tools, and so much more.

TechPowerUp has released the latest version of GPU-Z with GPU-Z v2.44.0 supporting a bunch of new chips -- including new designs from AMD, Intel, and NVIDIA.

GPU-Z 2.44.0 has support built-in for the NVIDIA GeForce RTX 3050, RTX 3080 12 GB, RTX 3070 Ti Mobile, RTX 3050 Ti Mobile (GA106), RTX 2060 12 GB, GT 1010, MX550, GTX 1650 Mobile (TU117-B), RTX A2000 (GA106-B), RTX A4500, A10G, A100 80 GB PCIe, CMP170HX, and the CMP70HX... and that's just NVIDIA.

Intel has new support with GPU-Z v2.44.0 with its new 12th Gen Core "Alder Lake" non-K processors, Alder Lake mobile processors, and Xeon processors based on the Rocket Lake CPU architecture are now supported.

Dying Light 2 will be supplied with new content until at least 2027.

Techland is going all out with Dying Light 2. Just like the first game, which had new content launching five years after release, the developers are prepared to support Dying Light 2 with new content for multiple years.

"It all starts on release, but it's just the beginning! We're planning to keep enhancing the game with DLCs, challenges, stories, events, and more for at least 5 years, and that's a minimum! You sure won't be bored!" Techland said on Twitter, revealing its new timeline roadmap for post-launch Dying Light 2 content.

Activision-Blizzard refuses to formally recognize the Game Workers Alliance, the proposed union of Raven Software's QA team, forcing a National Labor Relations Board election process.

Days ago, 34 people at Raven Software's QA team formally asked Activision-Blizzard to recognize their newly-formed union. The Game Workers Alliance, the QA testers became collectively known, would be the first video games union in the United States.

Activision-Blizzard refused to recognize the union through this initial declaration. Now The Game Workers Alliance has to go through the NLRB election process in order to be legally certified as a union.
