An anonymous reader quotes a report from Kotaku: On July 5, Zachtronics will be releasing Last Call BBS, a collection of stylish little puzzle games wrapped up in a retro PC gaming vibe. After 11 years in business (and even longer outside of commercial releases), a time which has seen the studio develop a cult following almost unrivaled in indie gaming, it will be the last new game Zachtronics will ever release. We spoke to founder Zach Barth to find out why. Named for founder Zach Barth, Zachtronics has spent most of those 11 years specializing in puzzle games (or variations on the theme). And pretty much every single one of them has been great (or at least interesting). [...] The result has been a succession of games that may not have been to everyone's tastes, but for those with whom they resonated, it was their shit. It's not hard seeing why: most of Zachtronics' games involved challenging puzzles, but also a deeply cool and interesting presentation surrounding them, such as the grimy hacker aesthetic of Exapunks, or the Advance Wars-like Mobius Front 83. Given those initial and superficial differences, it can sometimes be hard pinpointing exactly what makes a game so clearly a Zachtronics joint, but like love and art, when you see it you just know it. So it's sad, but also awesome in its own way, that 2022 will see the end of Zachtronics. Not because their publisher shuttered them, or because their venture capital funding ran out, or because Activision made them work on Call of Duty, or any other number of reasons (bankruptcy! scandal!) game developers usually close their doors. No, Zachtronics is closing because...they want to. "We're wrapping things up!" Barth tells Kotaku's Luke Plunkett. "Zachtronics will release Last Call BBS next month. We're also working on a long-awaited solitaire collection that we're hoping to have out by the end of the year. After that, the team will disband. We all have different ideas, interests, tolerances for risk, and so on, so we're still figuring out what we want to do next." "We felt it was time for a change. This might sound weird, but while we got very good at making 'Zachtronics games' over the last twelve years, it was hard for us to make anything else. We were fortunate enough to carve out a special niche, and I'm thankful that we've been able to occupy it and survive in it, but it also kept us locked into doing something we didn't feel like doing forever." Last Call BBS will be released on July 5 on Steam. You can view the trailer here.

Engineers in Sydney have demonstrated a quantum integrated circuit made up of just a few atoms. By precisely controlling the quantum states of the atoms, the new processor can simulate the structure and properties of molecules in a way that could unlock new materials and catalysts. New Atlas reports: The new quantum circuit comes from researchers at the University of New South Wales (UNSW) and a start-up company called Silicon Quantum Computing (SQC). It's essentially made up of 10 carbon-based quantum dots embedded in silicon, with six metallic gates that control the flow of electrons through the circuit. It sounds simple enough, but the key lies in the arrangement of these carbon atoms down to the sub-nanometer scale. Relative to each other, they're precisely positioned to mimic the atomic structure of a particular molecule, allowing scientists to simulate and study the structure and energy states of that molecule more accurately than ever before. In this case, they arranged the carbon atoms into the shape of the organic compound polyacetylene, which is made up of a repeating chain of carbon and hydrogen atoms with an alternating pattern of single and double carbon bonds between them. To simulate those bonds, the team placed the carbon atoms at different distances apart. Next, the researchers ran an electrical current through the circuit to check whether it would match the signature of a natural polyacetylene molecule -- and sure enough, it did. In other tests, the team created two different versions of the chain by cutting bonds at different places, and the resulting currents matched theoretical predictions perfectly. The significance of this new quantum circuit, the team says, is that it could be used to study more complicated molecules, which could eventually yield new materials, pharmaceuticals, or catalysts. This 10-atom version is right on the limit of what classical computers can simulate, so the team's plans for a 20-atom quantum circuit would allow for simulation of more complex molecules for the first time. The research has been published in the journal Nature.

Engineers at the European Space Agency (ESA) are getting ready for a Windows 98 upgrade on an orbiter circling Mars. The Verge reports: The Mars Express spacecraft has been operating for more than 19 years, and the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) instrument onboard has been using software built using Windows 98. Thankfully for humanity and the Red Planet's sake, the ESA isn't upgrading its systems to Windows ME. The MARSIS instrument on ESA's Mars Express was key to the discovery of a huge underground aquifer of liquid water on the Red Planet in 2018. This major new software upgrade "will allow it to see beneath the surfaces of Mars and its moon Phobos in more detail than ever before," according to the ESA. The agency originally launched the Mars Express into space in 2003 as its first mission to the Red Planet, and it has spent nearly two decades exploring the planet's surface. MARSIS uses low-frequency radio waves that bounce off the surface of Mars to search for water and study the Red Planet's atmosphere. The instrument's 130-foot antenna is capable of searching around three miles below the surface of Mars, and the software upgrades will enhance the signal reception and onboard data processing to improve the quality of data that's sent back to Earth. "We faced a number of challenges to improve the performance of MARSIS," explains Carlo Nenna, a software engineer at Enginium who is helping ESA with the upgrade. "Not least because the MARSIS software was originally designed over 20 years ago, using a development environment based on Microsoft Windows 98!"

Goldman Sachs is looking to raise $2 billion from investors to buy up distressed assets from troubled crypto lender Celsius, according to two people familiar with the matter. CoinDesk reports: The proposed deal would allow investors to buy up Celsius' assets at potentially big discounts in the event of a bankruptcy filing, the people said. Goldman Sachs appears to be gauging interest and soliciting commitments from Web3 crypto funds, funds specializing in distressed assets and traditional financial institutions with ample cash on hand, according to a person familiar with the situation. The assets, most likely cryptocurrencies having to be sold on the cheap, would then likely be managed by participants in the fundraising push. Celsius has tapped restructuring advisory firm Alvarez & Marsal, the Wall Street Journal reported Friday afternoon. Earlier this month, Celsius abruptly paused withdrawals, swaps, and transfers between accounts, citing "extreme market conditions." The disclosure sent bitcoin's price below $20,000 and prompted the firm's token to take a 60% tumble. As of Monday, the company said it's still working on "stabilizing [their] liquidity and operations."

Recent studies in humans and mice have shown that late nights and early mornings may cause long lasting damage to your brain. From a report: The sleep debt collectors are coming. They want you to know that there is no such thing as forgiveness, only a shifting expectation of how and when you're going to pay them back. You think of them as you lie in bed at night. How much will they ask for? Are you solvent? You fall asleep, then wake up in a cold sweat an hour later. You fall asleep, then wake up, drifting in and out of consciousness until morning. As most every human has discovered, a couple nights of bad sleep is often followed by grogginess, difficulty concentrating, irritability, mood swings and sleepiness. For years, it was thought that these effects, accompanied by cognitive impairments like lousy performances on short-term memory tests, could be primarily attributed to a chemical called adenosine, a neurotransmitter that inhibits electrical impulses in the brain. Spikes of adenosine had been consistently observed in sleep-deprived rats and humans. Adenosine levels can be quickly righted after a few nights of good sleep, however. This gave rise to a scientific consensus that sleep debt could be forgiven with a couple of quality snoozes -- as reflected in casual statements like "I'll catch up on sleep" or "I'll be more awake tomorrow." But a review article published recently in the journal Trends in Neurosciences contends that the folk concept of sleep as something that can be saved up and paid off is bunk. The review, which canvassed the last couple of decades of research on long term neural effects of sleep deprivation in both animals and humans, points to mounting evidence that getting too little sleep most likely leads to long-lasting brain damage and increased risk of neurodegenerative disorders like Alzheimer's disease. "This is really, really important in setting the stage for what needs to be done in sleep health and sleep science," said Mary Ellen Wells, a sleep scientist at the University of North Carolina, who did not contribute to the review.
