Samsung’s first 14nm SoC is a 64-bit, 8-core Exynos aimed at high-end phones

Samsung has just announced a new high-end Exynos 7 Octa SoC . It uses eight CPU cores—a combination of four high-end Cortex A57 cores and four low-end, power-saving Cortex A53 cores in a big.LITTLE configuration—and supports the 64-bit ARMv8 instruction set. However, its most significant new feature is Samsung’s new 14nm manufacturing process, which promises performance and power consumption improvements compared to the existing 20nm process. Samsung is already shipping eight-core 64-bit Exynos chips on its older 20nm process, most notably in the Galaxy Note Edge and some variants of the Galaxy Note 4. Compared to those chips, Samsung claims that the 14nm version “enables up to 20 percent faster speed, 35 percent less power consumption, and 30 percent productivity gain.” Those numbers don’t tell us much in terms of actual clock speeds or performance-per-watt numbers, but it’s safe to assume that the 14nm Exynos 7 will be able to run at higher clock speeds for longer while consuming less power. We don’t know anything about the new Exynos’ GPU yet. The 20nm Exynos 7 Octa uses a high-end Mail-T760 GPU from ARM, and we’ll probably see something similar in the 14nm version.

It’s now possible to map your home’s WiFi signal in 3D

We already know that it’s possible to map your home’s WiFi signal in 2D, but that doesn’t help if you’re holding your phone above your head to get connected. Step forward YouTuber CNLohr , who appears to have developed a reasonably low-tech way to analyze the WiFi strength of any 3D space. Using just a WiFi module and a CNC mill, he was able to detect the variability of the signal in an area and then create the funky visualization you see before you. In essence, the system is akin to WiFi radar, using a battery-powered ESP8266 chip to ping a device and measure the signal. If you attach an LED to the handheld hardware, it’ll change color depending on the relative quality in a given location. If you’ve been struggling with a signal blackspot in your home for a while, you can watch the clip below to find out how to build your own.

South American ice chemistry records rise of Incas, arrival of Spanish

Ice cores are often relied on to be natural archives of past climate, capturing information that predates both our measurements and our greenhouse gas emissions. They’re a way of having records of the natural world that we don’t have a history of. However, natural archives like these can also act as records of human history, either directly (via fossils or artifacts) or indirectly. In mountainous regions, glacial ice doesn’t go as deep into the past as in Greenland or Antarctica, but it can tell stories of the recent past with excellent resolution. Airborne pollutants, for example, stand out sharply in measurements of the ice. They don’t say “pure as the driven snow” for nothing. Not much of this kind of work has been done in South America, though. Some lake sediment archives have shown the influence of local mining, but the timeline was fuzzy. In a new study, a team led by Chiara Uglietti , now at Switzerland’s Paul Scherrer Institute, has produced a detailed ice core record of air pollution from Peru’s Quelccaya Ice Cap that goes back to the year 793.

Deaf group sues Harvard, MIT over online courses

The National Association for the Deaf (NAD) filed a lawsuit  (PDF) against Harvard and MIT yesterday, saying the two universities are violating the Americans with Disabilities Act because they don’t properly caption their online course offerings. Harvard’s online courses aren’t really intended for students at the Ivy League university. Rather, the thousands of videos made available are part of the University’s “commitment to equity,” an effort “to create effective, accessible avenues for people who desire to learn but who may not have an opportunity to obtain a Harvard education.” The problem with Harvard’s offering, NAD lawyers say, is that it leaves out hard-of-hearing people. “Much of Harvard’s online content is either not captioned, or is inaccurately or unintelligibly captioned, making it inaccessible for individuals who are deaf or hard of hearing,” the complaint reads. “Just as buildings without ramps bar people who use wheelchairs, online content without captions excludes individuals who are deaf or hard of hearing.” Read 6 remaining paragraphs | Comments

Wheel of Time TV pilot producers sue Robert Jordan’s widow for defamation

The tale of the late-night Wheel of Time pilot that aired in a paid infomercial slot on FXX has taken another odd turn. Producers Red Eagle Entertainment LLC and Manetheren LLC have filed a lawsuit in the United States District Court for central California against Harriet McDougal (widow of James Rigney, who wrote the Wheel of Time novels under the pen name Robert Jordan), her company, Bandersnatch Group Inc., and twenty unnamed other persons (“Does 1-20”). The suit alleges that McDougal’s statements about her lack of involvement in the pilot’s production constitute breach of contract, slander, and interference with contractual relations and prospective economic relations; the suit demands declaratory relief and a jury trial. With the pilot coming essentially out of nowhere and airing with no fanfare, very few fans of the series were even aware of its existence until after the fact; it was clear that the production was accomplished in very little time and on a minimal budget. The resulting effort (titled “Winter Dragon”) did not resemble the series prologue very closely, and it quickly drew strong rebuke from McDougal, who claimed the pilot was made “without my knowledge or cooperation,” and that no one from Robert Jordan’s estate has been involved in any way with it. McDougal claims that Universal currently holds the rights to the Wheel of Time TV series, not Red Eagle Entertainment, and that the pilot made no mention of Universal or her own company, the Bandersnatch Group. That statement was apparently interpreted by Red Eagle Entertainment LLC—the corporate entity that produced the pilot and also claims to hold the television rights to The Wheel of Time —as fighting words.

Assassin’s Creed movie officially in production

The long-awaited Assassin’s Creed movie is finally moving ahead, with Ubisoft revealing the film has officially entered production. The video game adaptation will be released on December 21, 2016. Word of the production came from the most mundane of places though—Ubisoft’s quarterly financial call. The publisher is co-producing the film with studio New Regency, which has had a golden period in recent years with films such as 12 Years a Slave , Birdman , and Gone Girl under its umbrella. “We have the pleasure to announce today that the green light has been given by New Regency, and the production has already started,” said Ubisoft’s CEO Yves Guillemot. “This is a very important milestone for the project and for our team on Assassin’s Creed .” Read 4 remaining paragraphs | Comments

Microscopic gold tubes can both detect and destroy cancer cells

There’s no doubt that doctors would prefer to treat cancer as soon as they spot it, and it looks like nanotechnology might give them that chance. Researchers at the University of Leeds have successfully tested gold nanotubes that are useful for both imaging and destroying cancer cells. Since the tubes absorb near-infrared light frequencies, which both generate heat and render human skin transparent, you only need to zap them with lasers of varying brightness to achieve multiple ends. You can use a relatively low brightness to reveal tumors, while high brightness will heat the tubes enough to kill nearby tumorous cells. The shape also has room for drugs, so you can deliver medicine at the same time. Scientists have only tried this approach in a mouse model of human cancer, so it’ll be a long while before the technique is ready for your local hospital. However, it might be worth the wait. Besides saving time, the gold nanotubes both enter and leave your body with minimal fuss; you aren’t as likely to grapple with side effects caused by methods like chemotherapy. If all goes well, you’d only need injections and laser blasts to deal with at least some life-threatening conditions. Filed under: Science Comments Via: EurekAlert Source: University of Leeds

Apple increases the maximum size of iOS app binaries for the first time ever

For the first time since the introduction of the App Store in 2008 , Apple is increasing the maximum size of the app binaries that developers can upload to iTunes Connect. The company announced today that the cap would increase from 2GB to 4GB , though this doesn’t affect the 100MB limit imposed on apps downloaded on cellular networks. iOS app binaries contain both the executable file and all of the images, sounds, and other assets that the app needs—everything from icons to splash screens to UI is all included in one big file. Because of how they’re packaged, these binaries can get rather large. Binaries include all the assets for all the devices they support. If you’re shipping a universal app that supports all iOS 8 devices, for example, you’ve got Retina iPhone assets, Retina and non-Retina iPad assets, and special “3x” assets specifically for the iPhone 6 Plus (Apple’s got a table here ). Universal apps include all of those assets, and the binary you download from the App Store is the same whether you’ve got an old iPhone 4S or a brand-new iPad Air 2. If you’re running on an iPhone, for example, a universal binary will still contain assets for other iPhones and iPads, increasing the amount of space the app needs even though some of those extra assets aren’t needed for your device. Xcode 6 partially supports vector graphics to ease the developer burden of maintaining and generating all these assets, but they’re still stored as PNG files when the binary is built and uploaded.

US Military Working On 3D Printing Exact Replicas of Bones & Limbs

ErnieKey writes The U.S. military is working with technology that will allow them to create exact virtual replicas of their soldiers. In case of an injury, these replicas could be used to 3D print exact medical models for rebuilding the injured patient’s body and even exact replica implants. Could we all one day soon have virtual backups of ourselves that we can access and have new body parts 3D printed on demand? Read more of this story at Slashdot.
