Cuba Turns On Submarine Internet Cable

angry tapir writes “A change in Internet traffic patterns over the past week suggests that Cuba may have turned on a fiber-optic submarine cable that links it to the global Internet via Venezuela. Routing analyst firm Renesys noticed that the Spanish telecommunications company Telefónica began routing Internet traffic to Cuba’s state telecommunications company, Empresa de Telecomunicaciones de Cuba S.A. (ETECSA). The Internet traffic is flowing with significantly lower latencies than before, indicating the connection is not solely using the three satellite providers that Cuba has relied on in the past for connectivity.” Read more of this story at Slashdot.

Replicating Hardest Known Biomaterial Could Improve Solar Cells and Batteries

cylonlover writes “Inspired by the tough teeth of a marine snail and the remarkable process by which they form, assistant professor David Kisailus at the University of California, Riverside is working toward building cheaper, more efficient nanomaterials. By achieving greater control over the low-temperature growth of nanocrystals (abstract), his research could improve the performance of solar cells and lithium-ion batteries, lead to higher-performance materials for car and airplane frames, and help develop abrasion-resistant materials that could be used for anything from specialized clothing to dental drills.” Read more of this story at Slashdot.

New Threadlike Carbon Nanotube Fiber Unveiled

Zothecula writes “At about 100 times the strength of steel and a sixth the weight, with impressive electrical conductive properties, carbon nanotubes (CNTs) have promised much since their discovery in 1991. The problem has been translating their impressive nanoscale properties into real-world applications on the macro scale. Researchers have now unveiled a new CNT fiber that conducts heat and electricity like a metal wire, is very strong like carbon fiber, and is flexible like a textile thread.” Read more of this story at Slashdot.

Telepresence Robot Rundown

DeviceGuru writes “A handful of innovative high-tech startups have recently emerged to create a new market: remote telepresence robots. With one of these robotic Avatars, you can wander around in the remote environment, chatting with coworkers and managers, attending meetings, and solving problems encountered through those interactions. InformationWeek’s Telepresence Robot Smackdown compares five such bots — the MantaroBot TeleMe, VGo Communications VGo, Anybots QB, Suitable Technologies Beam, and Revolve Robotics Kubi — and includes short videos demonstrating each. As the article concludes, ‘bear in mind that what we’re witnessing here is the emergence of a new industry; and if Moore’s Law applies here as it does to so many IT spheres, it won’t be long before these gadgets are inexpensive, commonplace, and far more flexible and intelligent.” Read more of this story at Slashdot.

Aaron Swartz Commits Suicide

maijc writes “Computer activist Aaron Swartz committed suicide yesterday in New York City. He was 26 years old. Swartz was ‘indicted in July 2011 by a federal grand jury for allegedly mass downloading documents from the JSTOR online journal archive with the intent to distribute them.’ He is best known for co-authoring the widely-used RSS 1.0 specification when he was 14, and as one of the early co-owners of Reddit.” Read more of this story at Slashdot.

Alleged ZeuS Botmaster Arrested For Stealing $100M From US Banks

Trailrunner7 writes “A 24-year-old Algerian man remains in a Thai jail awaiting extradition to the United States, where he is suspected of masterminding more than $100 million in global bank heists using the ZeuS and SpyEye Trojans. Malaysian authorities believe they’ve apprehended the hacker Hamza Bendelladj, who they say has been jetsetting around the world using millions of dollars stolen online from various banks. He was arrested at a Bangkok airport en route from Malaysia to Egypt. The hacker had developed a considerable reputation as a major operator of ZeuS-powered botnets and bragged about his exploits” Read more of this story at Slashdot.

Windows RT Jailbreak Tool Released

An anonymous reader writes “Earlier this week, reports surfaced that the Windows RT operating system had been jailbroken to allow for the execution of unsigned ARM desktop applications. Microsoft quickly issued a statement saying it does not consider the findings to be part of a security vulnerability, and applauded the hacker for his ingenuity. Now, a Windows RT jailbreak tool has been released.” Read more of this story at Slashdot.

Thousands of SCADA Devices Discovered On the Open Internet

Trailrunner7 writes with news of the continuing poor state of security for industrial control systems. From the article: “Never underestimate what you can do with a healthy list of advanced operator search terms and a beer budget. That’s mostly what comprises the arsenal of two critical infrastructure protection specialists who have spent close to nine months trying to paint a picture of the number of Internet-facing devices linked to critical infrastructure in the United States. It’s not a pretty picture. The duo … have with some help from the Department of Homeland Security (PDF) pared down an initial list of 500,000 devices to 7,200, many of which contain online login interfaces with little more than a default password standing between an attacker and potential havoc. DHS has done outreach to the affected asset owners, yet these tides turn slowly and progress has been slow in remedying many of those weaknesses. …The pair found not only devices used for critical infrastructure such as energy, water and other utilities, but also SCADA devices for HVAC systems, building automation control systems, large mining trucks, traffic control systems, red-light cameras and even crematoriums.” Read more of this story at Slashdot.

Fireflies Bring Us Brighter LEDs

Zothecula writes “Fireflies have helped an international team of scientists get over 50 percent more light out of existing LED bulbs. It was discovered that in the Photuris genus of firefly, scales in the insect’s exoskeleton possess optical qualities that boost the amount of bioluminescence that can shine through. Those same qualities were found to dramatically increase the light output of an LED bulb.” Read more of this story at Slashdot.
