Submission + - 3D Printer Able to Produce Skin w/Hair Follicles and Sweat Glands (computerworld.com)

Submitted by Lucas123
Lucas123 writes: A 3D printer developed by researchers at the University of Toronto is capable of using a patient's own cells to print skin. The technology could be used to treat burn victims and patients with other types of injuries, as well as to test pharmaceutical drugs. While still in pilot mode, the new PrintAlive Bioprinter is in the process of being commercialized by MaRS Innovations in collaboration with the Innovations and Partnerships Office (IPO) of the University of Toronto, whose labs have filed two patents on the device. The 3D skin printer works by placing the patient's cells along with other biomaterials into a micro-device, which then pushes them out through several channels. The biomaterials are then mixed, causing a chemical reaction that forms a "mosaic hydrogel", a sheet-like substance compatible with the growth of cells into living tissues. The hydrogel allows the various dermis cells to be seeded in precise and controlled patterns. The resulting thin film is then rolled up to crease thicker layers of tissue.

Submission + - Utilities Should Worry. Rooftop Solar Could Soon Cut Their Profit (computerworld.com)

Submitted by Lucas123
Lucas123 writes: A study by the Lawrence Berkeley National Laboratory predicts that distributed rooftop solar panel installations will grow from 0.2% market penetration today to 10% by 2022, during which time they're likely to cut utility profits from 8% to 41%. Using those same metrics, electricity rates for utility customers will grow only by as much as 2.7% over the next eight years. By comparison, the cost of electricity on average rose 3.1% from 2013 to 2014. The study was performed for the Office of Energy Efficiency and Renewable Energy under the U.S. Department of Energy. One of the main purposes of the study was to evaluate measures that could be pursued by utilities and regulators to reduce the financial impacts of distributed photovoltaics.

Submission + - Acer Launches First 4K Panel With NVIDIA G-Sync Technology On Board (hothardware.com)

Submitted by MojoKid
MojoKid writes: Save for a smattering of relatively small, 3K and 4K laptop displays, we haven't quite gotten to the same type of pixel density on the PC platform, that is available on today's high-end ultra-mobile devices. That said, the desktop display space has really heated up as of late and 4K panels have generated a large part of the buzz. Acer just launched the first 4K display with NVIDIA G-Sync technology on board. To put it simply, G-SYNC keeps a display and the output from an NVIDIA GPU in sync, regardless of frame rates or whether or not V-Sync is enabled. Instead of the monitor controlling the timing and refreshing at say 60Hz, the timing control is transferred to the GPU. The GPU scans a frame out to the monitor and the monitor doesn't update until a frame is done drawing, in lock-step with the GPU. This method completely eliminates tearing or frame stuttering associated with synchronization anomalies of standard panels. There are still some quirks with Windows and many applications that don't always scale properly on high-DPI displays, but the situation is getting better every day. If you're a gamer in the market for a 4K display, that's primed for gaming, the Acer XB280HK is a decent new option with this technology on board, though it does come at a bit of a premium at $799 versus standard 28-inch panels.

Submission + - IBM Solar Concentrator Can Produce12kW/day, and Act as Desalinator, Cooler (computerworld.com)

Submitted by Lucas123
Lucas123 writes: IBM Research and Switzerland-based Airlight Energy today announced a parabolic dish that increases the sun's radiation by 2,000 times while also producing fresh water and air conditioning. The new Concentrator PhotoVoltaics (CPV) system uses a dense array of water-cooled solar chips that can convert 80% of the sun's radiation into useful energy. The CPV, which looks like a 33-foot-high sunflower, can generate 12 kilowatts of electrical power and 20 kilowatts of heat on a sunny day — enough to power several average homes, according to Bruno Michel, the project's lead scientists at IBM Research in Switzerland.

Submission + - Backblaze Data Center Study Shows High Capacity Drive Failure Rates on Rise

Submitted by Lucas123
Lucas123 writes: Cloud storage service provider Backblaze released the latest data on failure rates for hard drives in its data center. The data comes from monitoring the health of more than 38,000 drives from Seagate, WD or HGST. The study showed that annual failure rates among 3TB models increased significantly over the past year. "The surprising (and bad) news is that Seagate 3TB drives are failing a lot more, with their failure rate jumping from 9% to 15%. The Western Digital 3TB drives have also failed more, with their rate going up from 4% to 7%,” the company's blog states. For example, Seagate’s Barracuda 7200.14 3TB hard drives with an average 1.9 year lifespan had a 15.7% annual failure rate. As with previous studies from Backblaze, the study also showed consumer drives are more reliable than enterprise drives.

She's not saying the things are not "very very dense" rather just that they never collapse further than the state that gravity can overcome the speed of light. I believe she's saying a black hole's mass would be "evenly" (or not) spread out over the volume encompassed by the event horizon, rather than in a singularity.

Lucas123 writes: Everyone wipes, according to a study by Fiberlink of small, medium and large corporations that use its remote data deletion software. Fiberlink looked at 130,000 devices running its MaaS360 mobile device management platform last year and found on average, businesses wipe 10% to 20% of their entire device population every year. The study also revealed 63% of devices are partially wiped and 37% are fully wiped. Additionally, 49% of wipes are done automatically and 51% are done by someone at the organization.

The study the level of sexual assault of trainees in academic fieldwork environments... was 26% of women and 6% of men reported experiencing sexual assault. According to a study by the CDC, 51.9 percent of surveyed women and 66.4 percent of surveyed men said they were physically assaulted as a child by an adult caretaker and/or as an adult by any type of attacker. More than half (54 percent) of the female rape victims identified by the survey were younger than age 18 when they experienced their first attempted or completed rape. Violence against women is primarily intimate partner violence: 64.0 percent of the women who reported being raped, physically assaulted, and/or stalked since age 18 were victimized by a current or former husband, cohabiting partner, boyfriend, or date. In comparison, only 16.2 percent of the men who reported being raped and/or physically assaulted since age 18 were victimized by such a perpetrator. Study: https://www.ncjrs.gov/pdffiles...

Submission + - Why the iPhone 6 Maintained the Same Base Memory as the iPhone 5 (computerworld.com)

Submitted by Lucas123
Lucas123 writes: When the iPhone 5 was launched two years ago, the base $199 (with wireless plan) model came with 16GB of flash memory. Fast forward to this week when the iPhone 6 was launched with the same capacity. Now consider that the cost of 16GB of NAND flash has dropped by more than 13% over the past two years. So why would Apple increase capacity on its $299 model iPhone 6 to 64GB (eliminating the 32GB model), but but keep the 16GB in the $199 model? The answer may lie in the fact that the 16GB iPhone is, and has been, by far the best selling model. IHS analyst Fang Zhang believes Apple is using that to push users to its iCloud storage service. Others believe restricting storage capacity allows Apple to afford the new features, like NFC and biometrics.

The Stardate is 5423.4. The Federation starship Enterprise arrives at the planet Gideon to begin diplomatic relations and invite the inhabitants to join the Federation. Gideon is reported to be a virtual paradise where the people live incredibly long lives in a nearly germ-free environment, but they refuse to allow anyone but Captain James Kirk from the Enterprise, to beam down. Upon beaming down, however, Kirk learns that the population has exploded to the point where the planet can barely contain the populace. Gideon's leaders plan is to infect the people with a human virus in an attempt to "control" the overpopulation problem caused by the people's long lifespans in a germ-free environment. So, as I see it, the problem is easily solved. Find a alien with a virus for which we have no cure.

Submission + - Once vehicles are connected to the Internet of Things, who guards your privacy? (computerworld.com)

Submitted by Lucas123
Lucas123 writes: Carmakers already remotely collect data from their vehicles, unbeknownst to most drivers, but once connected via in-car routers or mobile devices to the Internet, and to roadway infrastructure and other vehicles around them, that information would be accessible by the government or other undesired entities. Location data, which is routinely collected by GPS providers and makers of telematics systems, is among the most sensitive pieces of information that can be collected, according to Nate Cardozo, an attorney with the Electronic Frontier Foundation. "Not having knowledge that a third party is collecting that data on us and with whom they are sharing that data with is extremely troubling," Cardozo said. in-vehicle diagnostics data could also be used by government agencies to track driver behavior. Nightmare scenarios could include traffic violations being issued without law enforcement officers on the scene or federal agencies having the ability to track your every move in a car.
