NASA Will Create Fake Red And Green Clouds Near Virginia

An anonymous reader quotes CNET: The early morning hours on the U.S. East Coast might be unusually colorful as NASA plans to produce artificial blue-green and red clouds that may be visible from New York to North Carolina… It’s a test of a new system that helps scientists study the auroras and ionosphere. A NASA sounding rocket (a small, sub-orbital rocket often used in research) will launch from Wallops Flight Facility off the coast of Virginia and release several soda-sized canisters of vapor tracers in the upper atmosphere that may appear as colorful clouds. The tracers use vapors made up of lithium, barium and tri-methyl aluminum that react with other elements in the atmosphere to glow, letting researchers visually track the flows of ionized and neutral particles. It’s a bit like being able to dye the wind or ocean currents to be able to get a visual picture. CNN adds that “If you’re near the eastern U.S. coast, look toward the eastern horizon beginning about 4:30 a.m. The farther you are from the launch location, the lower the clouds will appear on the horizon.” Basically, try to adjust your gaze towards Virginia’s eastern shore — and if you’re not on the east coast, NASA is livestreaming the launch and posting updates on Facebook and Twitter.

Wikipedia’s Switch To HTTPS Has Successfully Fought Government Censorship

Determining how to prevent acts of censorship has long been a priority for the non-profit Wikimedia Foundation, and thanks to new research from the Harvard Center for Internet and Society, the foundation seems to have found a solution: encryption. From a report: HTTPS prevents governments and others from seeing the specific page users are visiting. For example, a government could tell that a user is browsing Wikipedia, but couldn’t tell that the user is specifically reading the page about Tiananmen Square. Up until 2015, Wikipedia offered its service using both HTTP and HTTPS, which meant that when countries like Pakistan or Iran blocked the certain articles on the HTTP version of Wikipedia, the full version would still be available using HTTPS. But in June 2015, Wikipedia decided to axe HTTP access and only offer access to its site with HTTPS. The Harvard researchers began by deploying an algorithm which detected unusual changes in Wikipedia’s global server traffic for a year beginning in May 2015. This data was then combined with a historical analysis of the daily request histories for some 1.7 million articles in 286 different languages from 2011 to 2016 in order to determine possible censorship events. After a painstakingly long process of manual analysis of potential censorship events, the researchers found that, globally, Wikipedia’s switch to HTTPS had a positive effect on the number censorship events by comparing server traffic from before and after the switch in June of 2015.

Researchers Found Perfect Contraceptives In Traditional Chinese Medicine

hackingbear writes: Researchers at U.C. Berkeley found a birth control that was hormone-free, 100 percent natural, resulted in no side effects, didn’t harm either eggs nor sperm, could be used in the long-term or short-term, and — perhaps the best part of all — could be used either before or after conception, from ancient Chinese folk medicine… “Because these two plant compounds block fertilization at very, very low concentrations — about 10 times lower than levels of levonorgestrel in Plan B — they could be a new generation of emergency contraceptive we nicknamed ‘molecular condoms, ‘” team leader Polina Lishko.

New Solar Plane Plans Non-Stop Flight Around The World

An anonymous reader quotes Bloomberg: [A] Russian tycoon and his Renova Group plan a record-breaking effort to send a plane around the world nonstop using only the power of the sun. If all goes well, a single pilot will fly for five days straight at altitudes of up to 10 miles, about a third higher than commercial airliners. The project isn’t just a stunt. The glider-style airplane with a 36-meter (120-foot) wingspan will be a test of technologies that are set to be used to build new generations of autonomous craft for the military and business, say aerospace experts. They will fly continuously, have far greater reach and control than satellites and expand broadcast, communication and spying capabilities around the globe… “Our flight should prove that it’s possible to make long-distance flights using solar energy, ” said Mikhail Lifshitz, Renova’s director of high-tech asset development and a qualified pilot-instructor. A “flying laboratory” test-plane will be ready by year-end, Lifshitz said in an interview. The plane will conserve power by slowly gliding down from the high altitudes at night — without ever touching the ground. In comparison a solar plane (partially funded by Google) already circled the earth last year — but it took 22 days, and made 17 different stops. Read more of this story at Slashdot.

JSON Feed Announced As Alternative To RSS

Reader Anubis IV writes: With Slashdot recently asking whether we still use RSS, it may come as a surprise that something interesting has happened in the world of news feeds this week. JSON Feed was launched as an alternative to RSS and Atom, eschewing the XML they rely on — which is frequently malformed and difficult to parse — in favor of a human readable JSON format that reflects the decades of combined experience its authors have in the field. The JSON Feed spec is a simple read that lays out a number of pragmatic benefits the format has over RSS and Atom, such as eliminating duplicate entries, adding the ability to paginate feeds so that old entries remain available, and reducing the need for clients to scrape sites to find images and other resources. Given that it’s authored by the developers behind one of the earliest, popular RSS clients and a recently Kickstarted blogging platform, the format is intended to address the common pain points currently faced by developers when producing and parsing feeds. While it remains to be seen whether JSON Feed will escape the chicken-and-egg stage of adoption, several clients have already added support for the fledging format in the week since its announcement, including Feedbin, Inoreader, and NewsBlur.

1.9 Million Bell Customer Email Addresses Stolen By ‘Anonymous Hacker’

Bell, Canada’s largest telecommunications company, said a hacker had accessed customer information containing about 1.9 million active email addresses and about 1, 700 names and active phone numbers. The breach was not connected to the recent global WannaCry malware attacks, the company added. From a report: The information appears to have been posted online, but the company could not confirm the leaked data was one and the same. “There is no indication that any financial, password or other sensitive personal information was accessed, ” the company wrote in a statement. Bell said the incident was unrelated to the massive spike in ransomware infections that affected an estimated 200, 000 computers in more than 150 countries late last week. It is not clear when the breach occurred, how the data was accessed, or how long the attacker had access to Bell’s systems. Read more of this story at Slashdot.

New Ransomware ‘Jaff’ Spotted; Malware Groups Pushing 5M Emails Per Hour To Circulate It

An anonymous reader writes: The Necurs botnet has been harnessed to fling a new strain of ransomware dubbed “Jaff”. Jaff spreads in a similar way to the infamous file-encrypting malware Locky and even uses the same payment site template, but is nonetheless a different monster. Attached to dangerous emails is an infectious PDF containing an embedded DOCM file with a malicious macro script. This script will then download and execute the Jaff ransomware. Locky — like Jaff — also used the Necurs botnet and a booby-trapped PDF, security firm Malwarebytes notes. “This is where the comparison ends, since the code base is different as well as the ransom itself, ” said Jerome Segura, a security researcher at Malwarebytes. “Jaff asks for an astounding 2 BTC, which is about $3, 700 at the time of writing.” Proofpoint reckons Jaff may be the work of the same cybercriminals behind Locky, Dridex and Bart (other nasty malware) but this remains unconfirmed. And Forcepoint Security Labs reports that malicious emails carrying Jaff are being cranked out at a rate of 5 million an hour on Thursday, or 13 million in total at the time it wrote up a blog post about the new threat.

Microsoft Finally Bans SHA-1 Certificates In Its Browsers

An anonymous reader quotes ZDNet: With this week’s monthly Patch Tuesday, Microsoft has also rolled out a new policy for Edge and Internet Explorer that prevents sites that use a SHA-1-signed HTTPS certificate from loading. The move brings Microsoft’s browsers in line with Chrome, which dropped support for the SHA-1 cryptographic hash function in January’s stable release of Chrome 56, and Firefox’s February cut-off… Apple dropped support for SHA-1 in March with macOS Sierra 10.12.4 and iOS 10.3… Once Tuesday’s updates are installed, Microsoft’s browsers will no longer load sites with SHA-1 signed certificates and will display an error warning highlighting a security problem with the site’s certificate.
