Hole In The Ozone Layer Smallest In 29 Years

An anonymous reader quotes the Weather Channel: The hole in the ozone layer over Antarctica is the smallest it’s been since 1988, NASA said. According to a press release, the hole in the Earth’s ozone layer is 1.3 million square miles smaller than last year and 3.3 million square miles smaller than 2015… This year, the hole grew to 7.6 million square miles. NASA and NOAA scientists said warmer temperatures and a stormier upper atmosphere helped keep damaging chemicals chlorine and bromine from eating ozone from the layer that protects the Earth’s surface from harmful ultraviolet rays… The hole that hovers over Antarctica has been slowly recovering, scientists say, due to an international ban on harmful chemicals that were previously used in refrigerants and aerosols. The hole was its largest in 2000 and measured 11.5 million square miles. Although recovery is underway, the size of the hole remains large compared to the 1980s, when the hole was first detected, NASA noted. And while there has been significant healing of the ozone layer in recent years, some scientists say full healing is a slow process and will not occur until sometime in the 22nd century, Yale Environment 360 reports. Others expect the Antarctic ozone hole to recover back to 1980 levels around 2070, NASA said. Read more of this story at Slashdot.

New VibWrite System Uses Finger Vibrations To Authenticate Users

An anonymous reader quotes a report from Bleeping Computer: Rutgers engineers have created a new authentication system called VibWrite. The system relies on placing an inexpensive vibration motor and receiver on a solid surface, such as wood, metal, plastic, glass, etc.. The motor sends vibrations to the receiver. When the user touches the surface with one of his fingers, the vibration waves are modified to create a unique signature per user and per finger. Rutgers researchers say that VibWrite is more secure when users are asked to draw a pattern or enter a code on a PIN pad drawn on the solid surface. This also generates a unique fingerprint, but far more complex than just touching the surface with one finger. During two tests, VibWrite verified users with a 95% accuracy and a 3% false positive rate. The only problem researchers encountered in the live trials was that some users had to draw the pattern or enter the PIN number several times before they passed the VibWrite authentication test. Besides improvements to the accuracy with which VibWrite can detect finger vibrations, researchers also plan to look into how VibWrite will behave in outdoor environments to account for varying temperatures, humidity, winds, wetness, dust, dirt, and other conditions. This new novel user authentication system is described in full in a research paper entitled “VibWrite: Towards Finger-input Authentication on Ubiquitous Surfaces via Physical Vibration.” Read more of this story at Slashdot.

Critical Flaws In Maritime Communications System Could Endanger Entire Ships

Orome1 shares a report from Help Net Security: IOActive security consultant Mario Ballano has discovered two critical cybersecurity vulnerabilities affecting Stratos Global’s AmosConnect communication shipboard platform. The platform works in conjunction with the ships’ satellite equipment, and integrates vessel and shore-based office applications, as well as provides services like Internet access for the crew, email, IM, position reporting, etc. The first vulnerability is a blind SQL injection in a login form. Attackers that successfully exploit it can retrieve credentials to log into the service and access sensitive information stored in it. The second one is a built-in backdoor account with full system privileges. “Among other things, this vulnerability allows attackers to execute commands with SYSTEM privileges on the remote system by abusing AmosConnect Task Manager, ” Bellano shared. The found flaws can be exploited only by an attacker that has access to the ship’s IT systems network, he noted, but on some ships the various networks might not be segmented, or AmosConnect might be exposed to one or more of them. The vulnerabilities were found in AmosConnect 8.4.0, and Stratos Global was notified a year ago. But Inmarsat won’t fix them, and has discontinued the 8.0 version of the platform in June 2017.

China Shuts Down Tens Of Thousands Of Factories In Widespread Pollution Crackdown

Buildings in China are shrouded in smog. From a report: China has implemented an unprecedented pollution crackdown in recent months as the country shuts down tens of thousands of factories. The effort is part of a national effort to address China’s infamous pollution and has affected wide swaths of China’s manufacturing sector. In total, it is estimated that 40 percent of all China’s factories have been shut down at some point in order to be inspected by environmental bureau officials. As a result of these inspections over 80, 000 factories have been hit with fines and criminal offenses as a result of their emissions. Safety officials have been moving from province to province (30 in total so far) shutting down factories as well as electricity and gas as they inspect the factories for meeting emissions requirements. This has resulted in late and missed orders, increased costs, and could ultimately result in higher prices on US shelves. Read more of this story at Slashdot.

Japanese Metal Manufacturer Faked Specifications To Hundreds of Companies

schwit1 writes: Kobe Steel, a major Japanese supplier of steel and other metals worldwide, has admitted that it faked the specifications to metals shipped to hundreds of companies over the past decade.Last week, Kobe Steel admitted that staff fudged reports on the strength and durability of products requested by its clients — including those from the airline industry, cars, space rockets, and Japan’s bullet trains. The company estimated that four percent of aluminum and copper products shipped from September 2016 to August 2017 were falsely labelled, Automotive News reported. But on Friday, the company’s CEO, Hiroya Kawasaki, revealed the scandal has impacted about 500 companies — doubling the initial count — and now includes steel products, too. The practice of falsely labeling data to meet customer’s specifications could date back more than 10 years, according to the Financial Times.For rockets the concern is less serious as they generally are not built for a long lifespan, but for airplanes and cars this news could be devastating, requiring major rebuilds on many operating vehicles.

Discovery of 50km Cave Raises Hopes For Human Colonisation of Moon

New submitter Zorro shares a report: Scientists have fantasised for centuries about humans colonising the moon. That day may have drawn a little closer after Japan’s space agency said it had discovered an enormous cave beneath the lunar surface that could be turned into an exploration base for astronauts. The discovery, by Japan’s Selenological and Engineering Explorer (Selene) probe, comes as several countries vie to follow the US in sending manned missions to the moon. Using a radar sounder system that can examine underground structures, the orbiter initially found an opening 50 metres wide and 50 metres deep, prompting speculation that there could be a larger hollow. This week scientists at the Japan Aerospace Exploration Agency (Jaxa) confirmed the presence of a cave after examining the hole using radio waves. The chasm, 50km (31 miles) long and 100 metres wide, appears to be structurally sound and its rocks may contain ice or water deposits that could be turned into fuel, according to data sent back by the orbiter, nicknamed Kaguya after the moon princess in a Japanese fairytale. Jaxa believes the cave, located from a few dozen metres to 200 metres beneath an area of volcanic domes known as the Marius Hills on the moon’s near side, is a lava tube created during volcanic activity about 3.5bn years ago.

Microsoft Has Already Fixed the Wi-Fi Attack Vulnerability; Android Will Be Patched Within Weeks

Microsoft says it has already fixed the problem for customers running supported versions of Windows. From a report: “We have released a security update to address this issue, ” says a Microsoft spokesperson in a statement to The Verge. “Customers who apply the update, or have automatic updates enabled, will be protected. We continue to encourage customers to turn on automatic updates to help ensure they are protected.” Microsoft is planning to publish details of the update later today. While it looks like Android and Linux devices are affected by the worst part of the vulnerabilities, allowing attackers to manipulate websites, Google has promised a fix for affected devices “in the coming weeks.” Google’s own Pixel devices will be the first to receive fixes with security patch level of November 6, 2017, but most other handsets are still well behind even the latest updates. Security researchers claim 41 percent of Android devices are vulnerable to an “exceptionally devastating” variant of the Wi-Fi attack that involves manipulating traffic, and it will take time to patch older devices.

Toshiba’s Fast-Charging Battery Could Triple the Range of Electric Vehicles

Big Hairy Ian quotes New Atlas: A key focus of electric vehicle (EV) makers is maximizing the range users can get from each charge, and for that reason new battery technologies are poised to play a huge part in driving their adoption. Toshiba has developed a new fast-charging battery it claims could allow EVs to travel three times as far as they do now, and then be fully recharged again in a matter of minutes. Toshiba’s SCiB (Super Charge ion Battery) has been around in various forms since 2007, with its chief claim to fame an ability to charge to 90 percent of capacity in just five minutes. It also boasts a life-span of 10 years and high levels of safety, and has found its way into a number of notable EVs, including Mitsubishi’s i MiEV and Honda’s Fit EV. The current SCiB uses lithium titanium oxide as its anode, but Toshiba says it has now come up with a better way of doing things. The next-generation SCiB uses a new material for the anode called titanium niobium oxide, which Toshiba was able to arrange into a crystal structure that can store lithium ions more efficiently. So much so, that the energy density has been doubled. Toshiba calls the battery “a game changing advance that will make a significant difference to the range and performance of EV, ” and hopes to put it “into practical application” in 2019.

8.5-Ton Chinese Space Station Will Crash To Earth In a Few Months

dryriver writes: China launched a space laboratory named Tiangong 1 into orbit in 2011. The space laboratory was supposed to become a symbol of China’s ambitious bid to become a space superpower. After two years in space, Tiangong 1 started experiencing technical failure. Last year Chinese officials confirmed that the space laboratory had to be scrapped. The 8.5 ton heavy space laboratory has begun its descent towards Earth and is expected to crash back to Earth within the next few months. Most of the laboratory is expected to burn up in earth’s atmosphere, but experts believe that pieces as heavy as 100 kilograms (220 pounds) may survive re-entry and impact earth’s surface. Nobody will be able to predict with any precision where those chunks of space laboratory will land on Earth until a few hours before re-entry occurs. The chance that anyone would be harmed by Tiangong-1’s debris is considered unlikely. When NASA’s SkyLab fell to earth in 1979, an Australian town fined them $400 — for littering.
