NASA Beams Hi-Def Video From Space Via Laser 38

An anonymous reader writes "NASA successfully beamed a high-definition video 260 miles from the International Space Station to Earth Thursday using a new laser communications instrument. Transmission of 'Hello, World!' as a video message was the first 175-megabit communication for the Optical Payload for Lasercomm Science (OPALS), a technology demonstration that allows NASA to test methods for communication with future spacecraft using higher bandwidth than radio waves." Last September, NASA's LADEE (Lunar Atmosphere and Dust Environment Explorer) showed that they could supply a lunar colony with broadband via lasers.

Rising Sea Levels Uncover Japanese War Dead In Marshall Islands 182

An anonymous reader writes "The foreign minister of the Marshall Islands says that, 'even the dead are affected' by climate change. From the article: 'Speaking at UN climate talks in Bonn, the Island's foreign minister said that high tides had exposed one grave with 26 dead. The minister said the bones were most likely those of Japanese troops. Driven by global warming, waters in this part of the Pacific have risen faster than the global average. With a high point just two metres above the waters, the Marshall Islands are one of the most vulnerable locations to changes in sea level.'"

Millions of Smart TVs Vulnerable To 'Red Button' Attack 155

An anonymous reader writes "Researchers from Columbia University's Network Security Lab discovered a flaw affecting millions of Smart TVs supporting the HbbTV standard. The flaw allows a radio-frequency attacker with a low budget to take control over tens of thousands of TVs in a single attack, forcing the TVs to interact with any website on their behalf — Academic paper available online."

Fixing China's Greenhouse Gas Emissions For Them 322

mdsolar writes: 'Paul Krugman, who won a Nobel Prize for understanding world trade, has proposed carbon tariffs as a way to get China to cut greenhouse gas emissions. He wrote, "China is enormously dependent on access to advanced-country markets — a lot of the coal it burns can be attributed, directly or indirectly, to its export business — and it knows that it would put this access at risk if it refused to play any role in protecting the planet. More specifically, if and when wealthy countries take serious action to limit greenhouse gas emissions, they're very likely to start imposing "carbon tariffs" on goods imported from countries that aren't taking similar action. Such tariffs should be legal under existing trade rules — the World Trade Organization would probably declare that carbon limits are effectively a tax on consumers, which can be levied on imports as well as domestic production. Furthermore, trade rules give special consideration to environmental protection. So China would find itself with strong incentives to start limiting emissions." As I read it, Article XX of the General Agreement on Tariffs and Trade does indeed allow us to unilaterally impose tariffs on China.'

Mesa 10.2 Improves Linux's Open-Source Graphics Drivers 58

An anonymous reader writes "Mesa 10.2 was introduced this week as the new shining example of what open source graphics (and open source projects in general) are capable of achieving. The latest release of this often underrepresented open source graphics driver project has many new OpenGL and driver features including a number of new OpenGL 4 extensions. The reverse-engineered Freedreno driver now poses serious competition to Qualcomm's Adreno driver, an OpenMAX implementation was added for Radeon video encoding support, Intel Broadwell support now works better, the software rasterizer supports OpenGL 3.3, and many other changes are present."

Report: Watch Dogs Game May Have Influenced Highway Sign Hacking 154

An anonymous reader writes 'Earlier this month, at least three U.S. states reported that a hacker had broken into electronic road signs above major highways, with the hacker leaving messages for people to follow him on Twitter. The Multi-State Information Sharing an Analysis Center (MS-ISAC) produced an intelligence report blaming a Saudi Arabian hacker that the organization says likely got the idea from Watch Dogs, a new video in which game play revolves around "hacking," with a focus on hacking critical infrastructure-based electronic devices in particular. "Watch Dogs allows players to hack electronic road signs, closed-circuit television cameras (CCTVs), street lights, cell phones and other systems. On May 27, 2014, the malicious actor posted an image of the game on his Twitter feed, demonstrating his interest in the game, and the compromise of road signs occurs during game play. CIS believes it is likely that a small percentage of Watch Dogs players will experiment with compromising computers and electronic systems outside of game play, and that this activity will likely affect SSLT [state, local, tribal and territorial] government systems and Department of Transportation (DOT) systems in particular." The signs allowed telnet and were secured with weak or default passwords. The report came out on the same day that The Homeland Security Department cautioned transportation operators about a security hole in some electronic freeway billboards that could let hackers display bogus warnings to drivers.'

Bill Watterson (briefly) Returns To Comics 119

New submitter amosh writes: 'Bill Watterson was the author of the immensely popular "Calvin and Hobbes" comic strip in the 80s and 90s, until he retired and removed himself entirely from the public eye. Since his retirement in 1995, he has become a recluse, and has not drawn a published daily comic strip — until now. This week, Watterson came out of exile to draw the 2nd panel of three of Stephan Pastis' "Pearls Before Swine" strips. Watterson has lost none of his style or talent, and a fourth strip — drawn by Pastis alone and published today, June 7 — is a lovely homage to Watterson's ending of Calvin and Hobbes. The Washington Post has the story of how it all happened.'

Robotics Engineers: "We Don't Want To Replace Humans. We Want To Enhance Humans. 124

Lucas123 writes: 'Scientists developing smart robotic prosthetics say the lines between robots and humans is beginning to blur and that someday soon people will be able to improve their body. For example, robotic prosthetics, using a built-in computer, 100 sensors, and 17 motors, can take natural cues from a user's residual limb, giving him or her the dexterity and grace to play a piano. Robotic exoskeletons have helped people suffering from paralysis walk again and the U.S. military is just weeks away from testing a new exoskeleton. And, more than six years ago, a University of Arizona researcher who had successfully connected a moth's brain to a robot predicted that by 2022 we'll be using "hybrid" computers that run a combination of technology and living organic tissue. "By utilizing technology, you're able to improve your body beyond anything you could do in the past," said Daniel Wilson, an engineer with degrees in machine learning and robotics from Carnegie Mellon University.'

Updating the Integrated Space Plan 65

garyebickford writes 'Space Finance Group (in which I'm a partner) has launched a Kickstarter to fund updating the "famous Integrated Space Plan", created by Ron Jones at Rockwell International in the late 1980s and early 1990s, and can be found on walls in the industry even today. The new Plan will be a poster, but also will provide the initial core data for a new website. The permanent link will be thespaceplan.com. As additional resources become available the website will be able to contain much more information, with (eventually) advanced data management (possibly including sources like Linked Data) and visualization tools to become a resource for education, research, entertainment, and business analytics. The group also hopes to support curated crowdsourcing of some data, and is talking to Space Development companies about providing data about themselves. They hope to be able to construct new timelines and show the relations between events and entities — companies, agencies, people, etc.'

Wikipedia Mining Algorithm Reveals the Most Influential People In History 231

KentuckyFC writes: 'In 1978, the American researcher Michael Hart published The 100: A Ranking of the Most Influential Persons in History, a book that became an international best seller. Since then, various others have published similar lists. But all suffer the same drawback: they are subjective list ultimately influenced by numerous cultural factors. Now data scientists have come up with a way to extract an objective list of the 100 most influential people in history using the network of links between biographical articles on Wikipedia and how they vary between 24 different language editions, including English, Chinese, Russian Arabic and so on. The researchers assume that people who are highly ranked in different language editions are influential across both language cultures and that the more appearances they make in different language editions, the more influential they are. But the actual ranking is done by PageRank-like algorithms that consider a biographical article important if it is pointed to by other important articles.

The resulting lists of the most influential men and women might surprise. The top PageRanked individual is Carl Linnaeus, the 18th century Swedish botanist who developed the modern naming scheme for plants and animals, followed by Jesus. The top PageRanked women are: Elizabeth II followed by Mary (mother of Jesus). For comparison, just under half of the top 100 most influential also appear in Hart's 1978 book. But this is just the beginning. By counting the individuals from one culture that influence other cultures, the team is able to work out which cultures have dominated others. And by looking only at people born before certain dates, they can see how the influence of different cultures has waxed and waned throughout 35 centuries of recorded history.'

Fasting Triggers Stem Cell Regeneration of Damaged, Old Immune System 148

schwit1 sends word of research showing that cycles of prolonged fasting can both protect the immune system from harm and also induce regeneration by causing stem cells to start renewing themselves. 'In both mice and a Phase 1 human clinical trial (abstract), long periods of not eating significantly lowered white blood cell counts. In mice, fasting cycles then "flipped a regenerative switch," changing the signaling pathways for hematopoietic stem cells, which are responsible for the generation of blood and immune systems, the research showed. "PKA is the key gene that needs to shut down in order for these stem cells to switch into regenerative mode. It gives the OK for stem cells to go ahead and begin proliferating and rebuild the entire system," explained [study author Valter Longo], noting the potential of clinical applications that mimic the effects of prolonged fasting to rejuvenate the immune system. "And the good news is that the body got rid of the parts of the system that might be damaged or old, the inefficient parts, during the fasting. Now, if you start with a system heavily damaged by chemotherapy or aging, fasting cycles can generate, literally, a new immune system."'

Microsoft Fixing Windows 8 Flaws, But Leaving Them In Windows 7 218

mask.of.sanity sends this news from El Reg: "Microsoft has left Windows 7 exposed by only applying security upgrades to its newest operating systems. Researchers found the gaps after they scanned 900 Windows libraries using a custom diffing tool and uncovered a variety of security functions that were updated in Windows 8 but not in 7. They said the shortcoming could lead to the discovery of zero day vulnerabilities. The missing safe functions were part of Microsoft's dedicated libraries intsafe.h and strsafe.h that help developers combat various attacks. [Video, slides.]"

Ask Slashdot: A 'Mavis Beacon' For Teaching Smartphone and Tablet Typing? 55

theodp writes: "Where have you gone, Mavis Beacon? A nation of smartphone and tablet typists could use your help. You've seen people type fast-and-furiously on smartphones and tablets, so you know it can be done, but how exactly do these one- and two-fingered wonders (YouTube video) manage to do so? Is it their reaction time? Technique? Both? Back in the day, touch-typing teachers showed kids the secrets to higher word-per-minute scores on their Smith Coronas. Later, typing tutor software got kids up-to-speed on PCs. So, with over 1 billion smartphones and 200 million or so tablets shipped in 2013, what are the best software and tutorials that teach mobile typing techniques? And what platform specific features — iOS, Android, WP8/Win8, BB — do you find make your mobile typing life a whole lot easier?"
