Dutch Scientist Proposes Circular Runways For Airport Efficiency

An anonymous reader quotes a report from Fast Company: While airport terminal architecture has a solid history of style and innovation, rarely is a proposal put forth to utterly redesign the runway. But that’s precisely the aim of Henk Hesselink, a Dutch scientist working with the Netherlands Aerospace Center. Dubbed the “endless runway, ” Hesselink’s brainchild is a 360-degree landing strip measuring more than two miles in diameter. Since airplanes would be able to approach and take off from any direction around the proposed circle, they wouldn’t have to fight against crosswinds. And three planes would be able to take off or land at the same time. Hesselink’s team uses flight simulators and computerized calculations to test the unconventional design, and have determined that round airports would be more efficient than existing layouts. With a central terminal, the airport would only use about a third of the land of the typical airport with the same airplane capacity. And there’s an added benefit to those living near airports: Flight paths could be more distributed, and thereby making plane noise more tolerable. BBC produced a video detailing Hesselink’s circular runway concept. The concept is fascinating but there are many questions the video does not answer. Phil Derner Jr. from NYC Aviation writes via Business Insider about some of those unanswered questions in his article titled “Why the circular runway concept wouldn’t work.” The fundamental issues discussed in his report include banked runway issues, curved runway issues, navigation issues, and airspace issues. What do you think of Hesselink’s concept? Do you think it is preposterous or shows promise? Read more of this story at Slashdot.

Researchers Discover A Surprising New Role for Lungs: Making Blood

schwit1 quotes ScienceAlert: In experiments involving mice, the team found that lungs produce more than 10 million platelets (tiny blood cells) per hour, equating to the majority of platelets in the animals’ circulation. This goes against the decades-long assumption that bone marrow produces all of our blood components. Researchers from the University of California, San Francisco also discovered a previously unknown pool of blood stem cells that makes this happen inside the lung tissue — cells that were incorrectly assumed to mainly reside in bone marrow. “This finding definitely suggests a more sophisticated view of the lungs — that they’re not just for respiration, but also a key partner in formation of crucial aspects of the blood, ” says one of the researchers, Mark R. Looney. The platelet-producing cells actually migrate from the bone marrow to the lungs. Read more of this story at Slashdot.

A 21st-Century Version Of OS/2 Warp May Be Released Soon

dryriver writes: A company named Arca Noae is working on a new release of the X86 OS/2 operating system code named “Blue Lion” and likely called ArcaOS 5 in its final release. Blue Lion wants to be a modern 21st Century OS/2 Warp, with support for the latest hardware and networking standards, a modern accelerated graphics driver, support for new cryptographic security standards, full backward compatibility with legacy OS/2, DOS and Windows 3.1 applications, suitability for use in mission-critical applications, and also, it appears, the ability to run “ported Linux applications”. Blue Lion, which appears to be in closed beta with March 31st 2017 cited as the target release date, will come with up to date Firefox browser and Thunderbird mail client, Apache OpenOffice, other productivity tools, a new package manager, and software update and support subscription to ensure system stability. It is unclear from the information provided whether Blue Lion will be able to run modern Windows applications. Read more of this story at Slashdot.

Ubuntu Linux 17.04 ‘Zesty Zapus’ Final Beta Now Available For Download

BrianFagioli writes: The final beta of Ubuntu 17.04 ‘Zesty Zapus’ became available for download Thursday. While it is never a good idea to run pre-release software on production machines, Canonical is claiming that it should be largely bug free at this point. In other words, if you understand the risks, it should be a fairly safe. Home users aside, this is a good opportunity for administrators to conduct testing prior to the official release next month. “The Ubuntu team is pleased to announce the final beta release of the Ubuntu 17.04 Desktop, Server, and Cloud products. Codenamed ‘Zesty Zapus’, 17.04 continues Ubuntu’s proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution, ” says Adam Conrad, Canonical. “The team has been hard at work through this cycle, introducing new features and fixing bugs.” Read more of this story at Slashdot.

The US Army Finally Gets The World’s Largest Laser Weapon System

It’s been successfully tested on trucks, as well as UAVs and small rockets, according to a video from Lockheed Martin, which is now shipping the first 60kW-class “beam combined” fiber laser for use by the U.S. Army. An anonymous reader quotes the Puget Sound Business Journal: Lockheed successfully developed and tested the 58 kW laser beam earlier this year, setting a world record for this type of laser. The company is now preparing to ship the laser system to the U.S. Army Space and Missile Defense Command/Army Forces Strategic Command in Huntsville, Alabama [according to Robert Afzal, senior fellow for Lockheed’s Laser and Sensor Systems in Bothell]. “We have shown that a powerful directed energy laser is now sufficiently light-weight, low volume and reliable enough to be deployed on tactical vehicles for defensive applications on land, at sea and in the air…” Laser weapons, which complement traditional kinetic weapons in the battlefield, will one day protect against threats such as “swarms of drones” or a flurry of rockets and mortars, Lockheed said.

1.6 Billion-Year-Old Plant Fossil Found In India

Complex multicellular life began 400 million years earlier than we thought, according to a Phys.org article shared by Slashdot reader William Robinson: Scientists found two kinds of fossils resembling red algae in uniquely well-preserved sedimentary rocks at Chitrakoot in central India. One type is thread-like, the other one consists of fleshy colonies. The scientists were able to see distinct inner cell structures and so-called cell fountains, the bundles of packed and splaying filaments that form the body of the fleshy forms and are characteristic of red algae… The oldest known red algae before the present discovery are 1.2 billion years old. The Indian fossils, 400 million years older and by far the oldest plant-like fossils ever found, suggest that the early branches of the tree of life need to be recalibrated.

Edge, VMWare, Safari, And Ubuntu Linux Hacked at Pwn2Own 2017

The 10th annual Pwn2Own hacking competition ended Friday in Vancouver. Some of the highlights: Ars Technica reports one team “compromised Microsoft’s heavily fortified Edge browser in a way that escapes a VMware Workstation virtual machine it runs in… by exploiting a heap overflow bug in Edge, a type confusion flaw in the Windows kernel and an uninitialized buffer vulnerability in VMware.” Digital Trends reports “Samuel Grob and Niklas Baumstark used a number of logic bugs to exploit the Safari browser and eventually take root control of the MacOS on a MacBook Pro, [and] impressed onlookers even more by adding a custom message to the Touch Bar which read: “pwned by niklasb and saelo.”Ubuntu 16.10 Linux was also successfully attacked by exploiting a flaw in the Linux 4.8 kernel, “triggered by a researcher who only had basic user access but was able to elevate privileges with the vulnerability to become the root administrative account user…” reports eWeek. “Chaitin Security Research Lab didn’t stop after successfully exploiting Ubuntu. It was also able to successfully demonstrate a chain of six bugs in Apple Safari, gaining root access on macOS.”Another attacker “leveraged two separate use-after-free bugs in Microsoft Edge and then escalated to SYSTEM using a buffer overflow in the Windows kernel.” None of the attendees registered to attempt an attack on the Apache Web Server on Ubuntu 16.10 Linux, according to eWeek, but the contest’s blog reports that “We saw a record 51 bugs come through the program. We paid contestants $833, 000 USD in addition to the dozen laptops we handed out to winners. And, we awarded a total of 196 Master of Pwn points.” Read more of this story at Slashdot.

Microsoft’s Project Scorpio Will Pack Internal PSU, 4K Game DVR Capture

According to an exclusive report from Windows Central, Microsoft’s upcoming “Project Scorpio” gaming console will feature an internal power supply unit (PSU), similar to the Xbox One S, and 4K game DVR and streaming at 60 frames-per-second (FPS). From the report: In Microsoft’s efforts to make Project Scorpio a true 4K system, it will also feature HEVC and VP9 codecs for decoding 4K streams for things such Netflix, just like the Xbox One S. It will also leverage HEVC for encoding 2160p, 60 frame-per-second (FPS) video for Game DVR and streaming. Microsoft’s Beam streaming service has been running public 4K stream tests for some time, and it’s now fair to assume it will not only be PC streamers who will benefit. Project Scorpio’s Game DVR will allow you to stream and record clips in 4K resolution with 60FPS, according to our sources, which is a massive, massive step up from the 720p, 30FPS you get on the current Xbox One. With every bit of information we receive about Project Scorpio, the theme of native 4K keeps appearing — not only for games, but also console features. We now believe Scorpio will sport 4K Game DVR, 4K Blu-ray playback, and 4K streaming apps, but the real showstopper will be the 4K games Microsoft will likely flaunt at E3 2017.

Proof Daylight Saving Time Is Dumb, Dangerous, and Costly

From a report on Bloomberg: The case for daylight saving time has been shaky for a while. The biannual time change was originally implemented to save energy. Yet dozens of studies around the world have found that changing the clocks has either minuscule or non-existent effects on energy use. The latest research suggests the time change can be harmful to our health and cost us money. The suffering of the spring time change begins with the loss of an hour of sleep. That might not seem like a big deal, but researchers have found it can be dangerous to mess with sleep schedules. Car accidents, strokes, and heart attacks spike in the days after the March time change. It turns out that judges, sleep deprived by daylight saving, impose harsher sentences. Some of the last defenders of daylight saving time have been a cluster of business groups who assume the change helps stimulate consumer spending. That’s not true either, according to recent analysis of 380 million bank and credit-card transactions by the JPMorgan Chase Institute. Read more of this story at Slashdot.

Chrome 57 Arrives With CSS Grid Layout and API Improvements

Google has launched Chrome 57 for Windows, Mac, and Linux. From a report on VentureBeat: Among the additions is CSS Grid Layout, API improvements, and other new features for developers. You can update to the latest version now using the browser’s built-in silent updater, or download it directly from google.com/chrome. Chrome is arguably more than a browser: With over 1 billion users, it’s a major platform that web developers have to consider. In fact, with Chrome’s regular additions and changes, developers have to keep up to ensure they are taking advantage of everything available. Chrome 57 implements CSS Grid Layout, a two-dimensional grid-based layout system for responsive user interface design. Elements within the grid can be specified to span multiple columns or rows, plus they can also be named so that layout code is easier to understand. The goal is to give developers more granular control, especially as websites are increasingly accessed on various screen sizes, so they can slowly move away from complex code that is difficult to maintain.
