Cassini has taken another spectacular image of its home planet

NASA As it continues to make some of its final flybys of the Saturn system, the Cassini spacecraft hasn’t entirely forgone looking back toward its home planet, Earth. And last week the spacecraft’s camera snapped a shot of Earth and the Moon (visible in a close-cropped view) from a distance of 1.4 billion km away. Some of Saturn’s rings are also visible in the new images, including the A ring (at top) with the Keeler and Encke gaps visible, and the F ring (at bottom). The Sun is behind the disk of Saturn from Cassini’s perspective, so the rings are backlit in this view. Read 1 remaining paragraphs | Comments

Researchers are using silk cocoons to store blood samples

When doctors draw blood for analysis, it’s vital that the sample either be immediately examined or refrigerated. That’s because the proteins which indicate various diseases will either be destroyed by enzymes in the blood or deformed by ambient heat. Either way, the sample quickly becomes useless if you leave it sitting out. However a team of researchers from Tufts University have developed a new way to store samples without having to put them on ice by using silkworm cocoons . The system works in a manner similar to conventional dried blood spot collection — wherein a drop of blood is deposited onto a piece of cardboard and allowed to dry. The Tufts method, however, relies on powdered silk and a separate silk-based solution. Mixing these two items with a sample of blood and allowing the result to dry preserved more viable blood proteins than both the normal drying or refrigeration methods. The team published its findings in the journal, Proceedings of the National Academy of Sciences on Monday. The technology itself is still very much in its preliminary development stages and won’t be showing up in your doctor’s office in the foreseeable future. Source: STAT News

J&J’s anesthesia-bot loses against its human counterparts

Just because robots can be more efficient than humans and can make certain processes cheaper doesn’t mean they’ll always come out on top. Case in point: Johnson & Johnson is pulling its anesthesia robot called Sedasys from the market over poor sales, according to Outpatient Surgery and Anesthesiology News . It was once a promising alternative to anesthesiologists, since it can bring down the cost of administering sedation from $2, 000 per procedure to $150 to $200. It eliminates the need for an anesthesia professional, after all, as it allows any nurse or doctor to put a patient under in the operating room. One of the reasons why it experienced such slow adoption rates is because the American Society of Anesthesiologists campaigned against it. The group eventually backed down after the machine was limited for use in routine procedures like colonoscopy, but by then, they’ve already done their job. Unfortunately, J&J now plans to lay off 3, 000 employees from its medical devices division due to its products’ (Sedasys included) poor sales, so it’s not a total victory for humans after all.

Quantum computer revolves around just 5 atoms

It’s no mean feat to find the factors of a very large number — even a supercomputer can take years to find all the multipliers. However, MIT researchers have found a way to clear this massive hurdle. They’ve built a quantum computer that discovers number factors using just five atoms. Four of the atoms are turned into logic gates using laser pulses that put them into superpositions (where they maintain two different energy states at once), while the fifth atom stores and delivers answers. The result is a computer that not only calculates solutions much more efficiently than existing quantum systems, but scales relatively easily. Need to get the factors for a larger number? Introduce more atoms. It’s a one-trick pony at the moment (it can only get factors for the number 15), and a truly complex computer would require “thousands” of simultaneous laser blasts to work. However, it could have big ramifications for the security world. A sufficiently powerful machine could end the use of any encryption that depends on factoring — a government agency or hacking team could easily crack codes that are otherwise near-impenetrable. On a basic level, this quantum factoring could also help solve math problems involving extremely large numbers (say, universe-scale calculations) that would normally be too daunting.

You can run over 1,000 Windows 3.1 programs in your browser

The Internet Archive has spent many years gathering and storing digital content from the past. It now hosts millions of web pages, texts, videos and audio snippets, but recently the site expanded its collection to include software, or more specifically, games . After making more than 2, 400 DOS titles available to play in the browser , the Internet Archive has embraced the GUI and done the same for Windows 3.1. It’s kicked things off by adding more than 1, 000 programs to its Windows 3.1 Software Library. The vast majority of them are games, including Taipei and Ski Free , but there’s plenty of browser-based shareware to get stuck into. There’s also a curated collection called the “Windows Showcase, ” which lists some of the best known programs and games from 20 years ago. It’s been made possible by Boris Gjenero’s EM-DOSbox emulator, which converts Windows runtimes into JavaScript code that can be interpreted by your browser. It’s what underpins the Archive’s DOS collection and testers have already used it to boot Windows 95 . That suggests we may only have to wait a short while to see more Windows programs added to the collection. Via: Internet Archive Blog Source: Windows 3.1 Software Library

Twisty fusion reactor goes online after 19 years of work

Germany just took fusion power one big, important step forward. The country’s Max Planck Institute for Plasma Physics has just switched on Wendelstein 7-X , the first large fusion reactor based on a twisty stellarator design. It’s only producing hydrogen plasma at the moment and won’t actually generate energy, but power isn’t really the point. Instead, it’ll serve as proof that stellarators could provide energy while operating continuously, unlike current (tokamak-based) fusion reactors that operate in short pulses. They should be safer, too. The inaugural test phase will run through mid-March, after which point it’ll get an upgrade to let it run hotter and longer. Eventually, it should discharge for up to 30 minutes at a time, and muster a heating power of 20 megawatts. The machine comes at a high price in more ways than one. It took roughly 19 years to design and build Wendelstein 7-X at a staggering cost of €1.2 billion, or about $1.3 billion. That’s a lot of effort for a testbed device. However, it could pay off if it leads to a much more powerful (not to mention less dangerous ) alternative to nuclear fission energy. Via: Motherboard Source: Max Planck Institute

Microsoft wants to put data centers at the bottom of the sea

Microsoft is on a mission to put its server farms at the bottom of the ocean . That might sound self-destructive, but there’s method in the madness — such an approach, the company believes, could make data centers faster, greener and easier to set up. In August last year, engineers placed an enormous steel capsule 30 feet underwater in the Pacific Ocean. Inside was a single data center rack, enveloped in pressurised nitrogen to keep it cool. The crew couldn’t reach it, at least not physically, but it didn’t matter — the setup worked, going so far as to run commercial tasks for Azure. The prototype submersible is called Leona Philpot, another nod to the Halo universe (after Cortana and Spartan). As the New York Times reports , the pod was kitted out with 100 sensors to measure every aspect of the underwater conditions — pressure, humidity and, perhaps most importantly, motion. The idea is that similar capsules could exist beneath the surface, linked to one another in a chain, and continually generate energy from the moving seawater. Looking ahead, there’s also hope that the aquatic environment could be used to naturally cool the racks. These aren’t the only advantages though. Server farms usually exist inland, far away from metropolitan areas. From a performance standpoint, their locations are inefficient for people living near the coastline — placing data centers offshore could, in theory, reduce latency for these places. Microsoft also believes that a smaller design could reduce installation times, from two years down to a staggering 90 days, making its operations cheaper and more flexible. The capsules themselves could also adopt new, innovative rack designs that don’t need to consider human interaction. There are environmental concerns, but Microsoft appears to be tackling them. It wants the data centers to be fully recyclable, and says its current prototype emits an “extremely” small amount of heat into the surrounding waters. Still, for people that love the ocean, this could be seen as yet another encroachment on mother nature. In the meantime, Microsoft has pulled Leona Philpot ashore — covered in barnacles, unsurprisingly — while it designs a new prototype that’s reportedly three times larger.

Electronic music gets its own televised awards show

Variety is reporting that Fox will broadcast the inaugural Electronic Music Awards on Saturday, April 23rd at 8pm. The network has teamed up with superstar DJ Paul Oakenfold to create the event as a celebration of the genre. It’ll feature red carpet coverage, interviews, the ceremony itself and performances from the world’s biggest artists. Read between the lines and you’ll assume that the move was born out of frustration with the Grammy’s traditional disdain for electronica. As Oakenfold says, he’s “thrilled to be part of an awards show that finally ” (emphasis ours) “recognizes and celebrates… one of the biggest music genres in the world.” You can feel the heat radiating off that burn from a mile away. Stuff that’s been made by a computer has always been treated as a poor cousin of things that are made more “traditionally.” Despite its pervasiveness, CGI gets a bum rap compared to practical effects , and it’s taken years for eSports to receive any degree of recognition from traditional broadcasters . Take a cursory look at the Grammy award categories and you can see where Oakenfold’s annoyance comes from. For instance, R&B and jazz both get five categories a piece, while electronic has to share a table with dance and has just two measly categories. Which seems a little bit unfair, don’t you think?

Scientists find a way to make concrete on Mars

If humans are ever going to have a long-term presence on Mars , they’ll need to make their own buildings — they can’t count on timely shipments from Earth. But how do they do that when the resources they have will share little in common with what they knew back home? Northwestern University researchers have an idea. They’ve developed a concrete that uses Mars’ native materials. You only have to heat sulphur until it melts, mix it with an equal part of Martian soil and let it cool. The finished concrete is very strong, easy to work with and recyclable — you just have to reheat it to get some building supplies back. Any need for Martian concrete is years away at best , but the discovery is still crucial. It suggests that explorers won’t have much trouble transitioning from short-term shelters to more permanent structures. Also, any would-be settlers can afford to pack light. Rather than carry every possible building they might want, they could bring just the essentials and build more once they’re established on the Red Planet’s surface.

Samsung’s Ultra HD Blu-ray player is coming soon for $399

There aren’t many Ultra HD Blu-ray players to choose from, but the first one you can buy is this one from Samsung. We’d seen it before at IFA last year, but this week Samsung announced the UBD-K8500 will go on sale in the US this March. Talking to reps from Samsung and the Ultra HD Association, I was told it could start selling as soon as February 22nd, and we expect to see the first Ultra HD discs arrive at the same time. Pre-orders are up on Samsung’s website and Amazon.com now for $399. The player itself is just like any other disc player you’ve seen, with a small arc detail along the bottom edge. In terms of features, it will play everything from 4K streaming apps to Blu-ray 3D discs, and it will even rip CDs for you (to WAV or MP3, which can be stored on a USB drive). As Samsung and Fox are collaborating on the UHD rollout, its booth featured a number of discs from the studio, including The Martian, Wild, Maze Runner: The Scorch Trials, Pan and others planned for early release in the format. I didn’t get a chance to play around with the device, but by all appearances it’s fast and capable. The days of the original Blu-ray players (remember the $1, 000 BD-P1000 and how long it took to load discs?) are well behind us, and if you’ve been waiting to jump into Ultra HD this should be a good entry point.
