Nanoparticle-based Fibers Could Lead To No-fade Textiles With Structural Color

SlashDot - Fri, 06/26/2015 - 12:37pm
JMarshall writes: Researchers have created fibers with structural color properties, no dyes needed. The researchers electrospun fiber mats from a solution of latex nanoparticles, creating fibers made of uniformly packed nanospheres. The resulting mats have structural color properties that depend on the size of the nanoparticles used. By using capillaries as molds, they obtained more uniformly packed spheres with even purer colors. The downside: the fibers so far are too weak to be useful. One solution could be to print the particles like ink on existing fibers.

Supreme Court Ruling Supports Same-Sex Marriage

SlashDot - Fri, 06/26/2015 - 11:14am
The U.S. Supreme Court issued Friday a landmark decision, ruling that marriage is a Constitutionally protected right to homosexual as well as heterosexual couples. The New York Times notes that last year, by refusing to hear appeals to decisions favoring same-sex marriage in five states, the court "delivered a tacit victory for gay rights, immediately expanding the number of states with same-sex marriage to 24, along with the District of Columbia, up from 19." (In the time since, several more states have expanded marriage to include gay couples.) Reuters expains a bit of the legal and political history of the movement which led to today's decision, and points out some of the countries around the world which have made similar moves already.

Reverse-Engineering a Frame of "Supreme Commander"

SlashDot - Fri, 06/26/2015 - 10:52am
An anonymous reader writes: When Supreme Commander was released 8 years ago, it redefined the RTS genre, with its real-time strategic zoom and its epic battles involving several thousands of units at once, while bringing a whole generation of PCs to their knees. Today an article revisits the process of rendering a frame of the game by reverse-engineering the API calls made to the GPU. All the techniques and algorithms are explained in detail, many of them still used in current video games.

Foxconn CEO Backpedals On Planned Robot Takeover

SlashDot - Fri, 06/26/2015 - 10:33am
itwbennett writes: For years now, Foxconn has been talking up plans to replace pesky humans with robot workers in its factories. Back in February, CEO Terry Gou said he expected the automation to account for 70 percent of his company's assembly line work in three years. But in the company's shareholder meeting Thursday, Gou said he had been misquoted and that "it should be that in five years, the robots will take over 30 percent of the manpower."

How Etak Built a Car Navigation System In 1985

SlashDot - Fri, 06/26/2015 - 9:52am
harrymcc writes: Thirty years ago, a startup called Etak released the Navigator, an in-car navigation system. It provided turn-by-turn driving directions despite the fact that GPS did not exist, and stored its maps--which Etak had to create itself--on cassette tapes. And some of its data and technologies are still in use in today's navigation apps. Over at Fast Company, Benj Edwards tells this amazing story. I remember reading about (and lusting over) this system back then, in the much-missed DAK catalog.

Lenovo Could Remake the ThinkPad X300 With Current Technologies

SlashDot - Fri, 06/26/2015 - 8:24am
MojoKid writes: The ThinkPad brand has been around for a long time; the first model was introduced by IBM way back in 1992. And although technological advances over the past two decades have lead to Lenovo ThinkPads that are lighter, much faster, and highly more cable than any model in the early 1990s could have ever imagined, there's still a clear visual link between yesteryear and today with regards to design cues. Well, apparently, Lenovo is seriously toying with the idea of making a "unique" model that would incorporate some of the strong ThinkPad language that has been erased in recent years. "Imagine a blue enter key, 7 row classic keyboard, 16:10 aspect ratio screen, multi-color ThinkPad logo, dedicated volume controls, rubberized paint, exposed screws, lots of status LEDs, and more. Think of it like stepping into a time machine and landing in 1992, but armed with today's technology." It might not be for everyone but some execs at Lenovo think there might be a market for it.

France Could Offer Asylum To Assange, Snowden

SlashDot - Fri, 06/26/2015 - 7:41am
HughPickens.com writes: The Intercept reports that in the aftermath of the NSA's sweeping surveillance of three French presidents, French Justice Minister Christiane Taubira thinks National Security Agency whistleblower Edward Snowden and WikiLeaks founder Julian Assange might be allowed to settle in France. Taubira was asked about the NSA's surveillance of three French presidents, disclosed by WikiLeaks this week, and called it an "unspeakable practice." Taubira's comments echoed those in an editorial in France's leftist newspaper Libération that France should respond to the U.S.'s "contempt" for its allies by giving Edward Snowden asylum. France would send "a clear and useful message to Washington, by granting this bold whistleblower the asylum to which he is entitled," wrote editor Laurent Joffrin in an angry editorial titled "Un seul geste" — or "A single gesture." (google translate) If Paris offers Snowden asylum, it will be joining several other nations who have done so in the past, including Bolivia, Nicaragua and Venezuela. However, Snowden is still waiting in Moscow to hear from almost two dozen other countries where he has requested asylum.

Black Hole Awakens After 26 Years

SlashDot - Fri, 06/26/2015 - 7:14am
schwit1 writes: For the first time since 1989, the black hole in V404 Cygni, a system comprising a black hole and a star, has reawakened, suddenly emitting high energy outbursts beginning on June 15. The outbursts are probably occurring because the black hole is gobbling up material that has fallen into it. While the 1989 outburst helped astronomers gain their first understand of the behavior of a black hole in a star system, this outburst will help them understand how such systems evolve and change over time. The European Space Agency (ESA) reports: "First signs of renewed activity in V404 Cygni were spotted by the Burst Alert Telescope on NASA's Swift satellite, detecting a sudden burst of gamma rays, and then triggering observations with its X-ray telescope. Soon after, MAXI (Monitor of All-sky X-ray Image), part of the Japanese Experiment Module on the International Space Station, observed an X-ray flare from the same patch of the sky. These first detections triggered a massive campaign of observations from ground-based telescopes and from space-based observatories, to monitor V404 Cygni at many different wavelengths across the electromagnetic spectrum."

Controversial Trial of Genetically Modified Wheat Ends In Disappointment

SlashDot - Fri, 06/26/2015 - 6:24am
sciencehabit writes: A controversial GM wheat trial has failed after more than £2 million of public money was spent protecting it from GM opponents. Researchers had hoped that the wheat modified to produce a warning pheromone would keep aphids away and attract their natural enemies, reducing the need for insecticides. Despite showing promise in the laboratory, the field trial failed to show any effect. “If you make a transgenic plant that produces that alarm continuously, it’s not going to work,” ecologist Marcel Dicke of Wageningen University in the Netherlands says. “You have a plant crying wolf all the time, and the bugs won’t listen to it any longer.”

Students Win Prize For Color-Changing Condoms That Detect STDs

SlashDot - Fri, 06/26/2015 - 2:05am
New submitter PJ6 writes: Three students attending the Isaac Newton Academy in the UK won the Healthcare Category of the Teen Tech Awards, for their idea to use antibodies to create color-changing condoms to recognize STDs. They say the material, which is still in the concept stage, will turn green for chlamydia, yellow for herpes, purple for HPV, and blue for syphilis. The BBC reports: "The boys said they still have to test the science and feasibility of their idea. They want to work with a university on the science and say they've already been contacted by a condom company which is interested in working with them on developing the concept further."

Put Your Enterprise Financial Data In the Cloud? Sure, Why Not

SlashDot - Fri, 06/26/2015 - 12:30am
jfruh writes: For many, the idea of storing sensitive financial and other data in the cloud seems insane, especially considering the regulatory aspects that mandate how that data is protected. But more and more organizations are doing so as cloud providers start presenting offerings that fulfill regulatory needs — and people realize that information is more likely to be accidentally emailed out to the wrong address than hacked.

Stellar Rejuvenation: Some Exoplanets May Get Facelifts

SlashDot - Thu, 06/25/2015 - 9:03pm
astroengine writes: Astronomers may have discovered an exoplanet that has found the elixir to planetary youth, knocking billions of years off its age. Until now, stellar rejuvenation has been pure conjecture, but after studying a white dwarf star called PG 0010+280, it turns out that one very interesting explanation for an excess in detected infrared radiation may be down to the presence of an exoplanet that was given a facelift. "When planets are young, they still glow with infrared light from their formation," said Michael Jura of the University of California, Los Angeles, co-author of the study published in The Astrophysical Journal. "But as they get older and cooler, you can't see them anymore. Rejuvenated planets would be visible again." This rejuvenation happens when stellar material shedding from a dying red giant star falls onto an exoplanet, causing heating and making it appear younger.

Google Asks Android Developers To Show Sensitivity To Disasters and Atrocity

SlashDot - Thu, 06/25/2015 - 7:31pm
Mark Wilson writes: Today Google revealed an updated version of its Google Play Developer Program Policies. There aren't actually all that many changes or additions, but those that are present are quite interesting. Google is clamping down on the problem of impersonation, making it clearer that it is not permissible to mislead users by imitating other apps, making false claims, or suggesting endorsements that do not exist. One of the more intriguing changes to the document sees Google calling on developers to show sensitivity to evens such as natural disasters, war, and death. Any apps or other content that attempt to benefit by exploiting such events are explicitly banned.

WiFi Offloading is Skyrocketing

SlashDot - Thu, 06/25/2015 - 6:50pm
dkatana writes: WiFi Offloading is skyrocketing. This is the conclusion of a new report from Juniper Research, which points out that the amount of smartphone and tablet data traffic on WiFi networks will will increase to more than 115,000 petabytes by 2019, compared to under 30,000 petabytes this year, representing almost a four-fold increase. Most of this data is offloaded to consumer's WiFi by the carriers, offering the possibility to share your home internet connection in exchange for "free" hotspots. But this article on InformationWeek Network Computing also warns that "The capacity of the 2.4GHz band is reaching its limit. [...] the growing number of WiFi devices using unlicensed bands is seriously affecting network efficiency. Capacity is compromised by the number of simultaneously active devices, with transmission speeds dropping as much as 20% of the nominal value. With the number of IoT and M2M applications using WiFi continuously rising, that could become a serious problem soon."

DARPA Is Already Working On Designer Organisms To Terraform Mars

SlashDot - Thu, 06/25/2015 - 6:08pm
MarkWhittington writes: Space visionaries dream of a time when human beings will not only settle Mars, but will terraform the Red Planet into something more Earth-like, with a breathable atmosphere, running water, and a functioning biosphere. Evidence exists that Mars was more or less Earth-like billions of years ago before the atmosphere leached away into space and the water became frozen under the ground and at the poles. Terraforming Mars is decades away from the beginning and probably centuries away from the end. But DARPA, the Defense Advanced Research Projects Agency, is already genetically engineering organisms that will help turn the Red Planet blue, according to a story in Motherboard.

Average Duration of Hiring Process For Software Engineers: 35 Days

SlashDot - Thu, 06/25/2015 - 5:24pm
itwbennett writes: Despite the high demand for tech workers of pretty much all stripes, the hiring process is still rather drawn out, with the average time-to-hire for Software Engineers taking 35 days. That's one of the findings of a new study from career site Glassdoor. The study, led by Glassdoor's Chief Economist Dr. Andrew Chamberlain, analyzed over 340,000 interview reviews, covering 74,000 unique job titles, submitted to the site from February 2009 through February 2015. Glassdoor found that the average time-to-hire for all jobs has increased 80% (from 12.6 days to 22.9 days) since 2010. The biggest reason for this jump: The increased reliance on screening tests of various sorts, from background checks and skills tests to drug tests and personality tests, among others.
