Hacking Internet Connected Light Bulbs

An anonymous reader writes We’ve been calling it for years — connect everything in your house to the internet, and people will find a way to attack it. This post provides a technical walkthrough of how internet-connected lighting systems are vulnerable to outside attacks. Quoting: “With the Contiki installed Raven network interface we were in a position to monitor and inject network traffic into the LIFX mesh network. The protocol observed appeared to be, in the most part, unencrypted. This allowed us to easily dissect the protocol, craft messages to control the light bulbs and replay arbitrary packet payloads. … Monitoring packets captured from the mesh network whilst adding new bulbs, we were able to identify the specific packets in which the WiFi network credentials were shared among the bulbs. The on-boarding process consists of the master bulb broadcasting for new bulbs on the network. A new bulb responds to the master and then requests the WiFi details to be transferred. The master bulb then broadcasts the WiFi details, encrypted, across the mesh network. The new bulb is then added to the list of available bulbs in the LIFX smart phone application.” Read more of this story at Slashdot.

Goldman Sachs Demands Google Unsend One of Its E-mails

rudy_wayne (414635) writes A Goldman Sachs contractor was testing internal changes made to Goldman Sachs system and prepared a report with sensitive client information, including details on brokerage accounts. The report was accidentally e-mailed to a ‘gmail.com’ address rather than the correct ‘gs.com’ address. Google told Goldman Sachs on June 26 that it couldn’t just reach into Gmail and delete the e-mail without a court order. Goldman Sachs filed with the New York Supreme Court, requesting “emergency relief” to avoid a privacy violation and “avoid the risk of unnecessary reputational damage to Goldman Sachs.” Read more of this story at Slashdot.

Chinese Company ‘3D-Prints 10 Buildings In One Day

Lucas123 writes: A company in China has used additive manufacturing to print 10 single-room buildings out of recycled construction materials in under a day as offices for a Shanghai industrial park. The cost: about $5, 000 each. The company, Suzhou-based Yingchuang New Materials, used four massive 3D printers supplied by the WinSun Decoration Design Engineering Co. Each printer is 20 feet tall, 33 feet wide and 132 feet long. Like their desktop counterparts, the construction-grade 3D printers use fused deposition modeling (FDM), where instead of thermoplastics layer after layer of cement is deposited atop one another. The cement contains hardeners that make each layer firm enough for the next. Yingchuang’s technique builds structures off site in a factory one wall at a time. The structures are then assembled onsite. The technique is unlike U.S.-based Contour Crafting, a company whose 3D printing technology to form the entire outer structure of buildings at once, The Yingchuang factory and research center, a 33, 000 square foot building, was also constructed using the 3D printing manufacturing technique. It only took one month to construct. Read more of this story at Slashdot.

India Launches Five Foreign Satellites

vasanth writes: “India has put into orbit five foreign satellites, including one built by France two from Canada and one each from Singapore and Germany. The PSLV (Polar Satellite Launch Vehicle) has so far successfully launched 67 satellites, including 40 foreign ones, into space. The PSLV costs about 17 million USD and the cost is seen as a major advantage India has over other countries in terms of commercial launches. When talking about the cost of the project, the Prime Minister of India noted that the launch was cheaper than Hollywood film Gravity. Read more of this story at Slashdot.

Cambridge Team Breaks Superconductor World Record

An anonymous reader writes University of Cambridge scientists have broken a decade-old superconducting record by packing a 17.6 Tesla magnetic field into a golf ball-sized hunk of crystal — equivalent to about three tons of force. From the Cambridge announcement: “A world record that has stood for more than a decade has been broken by a team led by University of Cambridge engineers, harnessing the equivalent of three tonnes of force inside a golf ball-sized sample of material that is normally as brittle as fine china. The Cambridge researchers managed to ‘trap’ a magnetic field with a strength of 17.6 Tesla — roughly 100 times stronger than the field generated by a typical fridge magnet — in a high temperature gadolinium barium copper oxide (GdBCO) superconductor, beating the previous record by 0.4 Tesla.” Read more of this story at Slashdot.

Windows 9 To Win Over Windows 7 Users, Disables Start Screen For Desktop

DroidJason1 writes One of Microsoft’s main goals with Windows 9, the next major version of Windows, is to win over Windows 7 hold outs. The operating system will look and work differently based on hardware type. Microsoft is looking to showcase the desktop for desktop and laptop users, while two-in-one devices like the Surface Pro or Lenovo Yoga will support switching between the Metro interface and the classic desktop interface. The new desktop will allow Modern UI apps to run in windowed mode, and have Modern UI apps pinned to the Start Menu instead of a Start Screen. There will also be a mini-start menu. Microsoft is looking to undo the usability mistakes it made with Windows 8 for those who are not on a touch device. WIndows 9 is expected around spring of 2015. Read more of this story at Slashdot.

Astronomers Discover Earth-Sized Diamond

ygslash (893445) writes Astronomers at the National Radio Astronomy Observatory announced that they have discovered what appears to be the coolest white dwarf ever detected. The white dwarf is formerly a star similar to our own sun which, after expending all of its fuel, has cooled to less than a chilly 3000 degrees Kelvin and contracted to a size approximately the same as Earth. A white dwarf is composed mostly of carbon and oxygen, and the astronomers believe that at that temperature it would be mostly crystallized, forming something like a huge diamond.

Will 7nm and 5nm CPU Process Tech Really Happen?

An anonymous reader writes “This article provides a technical look at the challenges in scaling chip production ever downward in the semiconductor industry. Chips based on a 22nm process are running in consumer devices around the world, and 14nm development is well underway. But as we approach 10nm, 7nm, and 5nm, the low-hanging fruit disappears, and several fundamental components need huge technological advancement to be built. Quoting: “In the near term, the leading-edge chip roadmap looks clear. Chips based on today’s finFETs and planar FDSOI technologies will scale to 10nm. Then, the gate starts losing control over the channel at 7nm, prompting the need for a new transistor architecture. … The industry faces some manufacturing challenges beyond 10nm. The biggest hurdle is lithography. To reduce patterning costs, Imec’s CMOS partners hope to insert extreme ultraviolet (EUV) lithography by 7nm. But EUV has missed several market windows and remains delayed, due to issues with the power source. … By 7nm, the industry may require both EUV and multiple patterning. ‘At 7nm, we need layers down to a pitch of about 21nm, ‘ said Adam Brand, senior director of the Transistor Technology Group at Applied Materials. ‘That’s already below the pitch of EUV by itself. To do a layer like the fin at 21nm, it’s going to take EUV plus double patterning to round out of the gate. So clearly, the future of the industry is a combination of these technologies.'” Read more of this story at Slashdot.

Scientists Successfully Grow Full Head of Hair On Bald Man

realized writes: “A man with almost no hair on his body has grown a full head of it after a novel treatment by doctors at Yale University. The patient had previously been diagnosed with both alopecia universalis, a disease that results in loss of all body hair, and plaque psoriasis, a condition characterized by scaly red areas of skin. The only hair on his body was within the psoriasis plaques on his head. He was referred to Yale Dermatology for treatment of the psoriasis. The alopecia universalis had never been treated. After two months on tofacitinib [an FDA-approved arthritis drug] at 10 mg daily, the patient’s psoriasis showed some improvement, and the man had grown scalp and facial hair — the first hair he’d grown there in seven years. After three more months of therapy at 15 mg daily, the patient had completely regrown scalp hair and also had clearly visible eyebrows, eyelashes, and facial hair, as well as armpit and other hair, the doctors said.” Read more of this story at Slashdot.

First Movie of an Entire Brain’s Neuronal Activity

KentuckyFC (1144503) writes “One of the goals of neuroscience is to understand how brains process information and generate appropriate behaviour. A technique that is revolutionising this work is optogenetics–the ability to insert genes into neurons that fluoresce when the neuron is active. That works well on the level of single neurons but the density of neurons in a brain is so high that it has been impossible to tell them apart when they fluoresce. Now researchers have solved this problem and proved it by filming the activity in the entire brain of a nematode worm for the first time and making the video available. Their solution comes in two parts. The first is to ensure that the inserted genes only fluoresce in the nuclei of the neurons. This makes it much easier to tell individual neurons in the brain apart. The second is a new techniques that scans the entire volume of the brain at a rate of 80 frames per second, fast enough to register all the neuronal activity within it. The researchers say their new technique should allow bigger brains to be filmed in the near future opening up the potential to study how various creatures process information and trigger an appropriate response for the first time.” Read more of this story at Slashdot.
