Submission + - Microphone 32 X more sensitive has been invented (arxiv.org)

Taco Cowboy writes: A microphone which is 32 X more sensitive than regular microphone has recently been invented

Most microphones have the same componentry as a loudspeaker – in fact, they’re loudspeakers working in reverse, turning sound into electrical currents. When you speak, the sound waves travel towards the microphone, which impact a membrane that then vibrates. These vibrations are transferred to a metallic coil that then moves back and forth across a permanent magnet. A temporary electromagnet is created by the interaction of the magnetic field with the coil, and an electrical current is generated, which travels to an amplifier or a sound recording device. Nickel is normally used in the construction of the membrane

Replacing the Nickel with a graphine based membrane 30n carbon-atom thick, showed a remarkable 32-fold increase in sensitivity across a significant part of the audio spectrum: up to 11 kilohertz, across a dizzying array of amplitudes

The researchers also simulated a 300-layer thick graphene membrane, which has the potential to be even more sensitive; it could hypothetically detect frequencies of up to one megahertz, which is in the ultrasonic part of the spectrum. This has yet to be tested experimentally, though

This research shows that it is demonstrably possible for graphene to be used in a new generation of highly sensitive microphones, which will pick up far more sound detail than regular microphones do at present. Excitingly, highly sensitive ultrasonic microphones may also be on the cards

Comment TFA is a filthy liberal propaganda ! (Score 0) 487

Exhibit A, the embedded video in the following link showed a 'blow-by-blow' demonstration of how to stab and kill Jews


Exhibit B, a 'tutorial video' of how to stab, where to stab, produced by islamic terrorists


DICE should be ashamed to publicize such trashy liberal propaganda !!

Submission + - Diamond Nanothreads Could Support Space Elevator (space.com)

Taco Cowboy writes: Researchers in Penn State University discovered a way to produce ultra-thin diamond nanothreads that could be ideal for a space elevator

The team, led by chemistry professor John Badding, applied alternating cycles of pressure to isolated, liquid-state benzene molecules and were amazed to find that rings of carbon atoms assembled into neat and orderly chains

While they were expecting the benzene molecules to react in a disorganized way, they instead created a neat thread 20,000 times smaller than a strand of human hair but perhaps the strongest material ever made

Just recently, a team from the Queensland University of Technology in Australia modeled the diamond nanothreads using large-scale molecular dynamics simulations and concluded that the material is far more versatile than previously thought and has great promise for aerospace properties. The simulation was published in early November

Comment Education can never replace intelligence (Score 2) 202

... it just means that as education prevails, people are less prone to fall for insane cults ...

Too many people are confusing 'Education' with 'Intelligence'

***Education can never replace Intelligence***

There are so many cases where highly educated people - even Engineers / Surgeons - have joined cults

Many of the 'volunteers' for the Islamic State are highly educated people - no, they are not the ones you see in those gruesome videos, but they joined Islamic State and work as administrators / accountants / planners and keep the bureaucracy running

Another example: The cult of Bhagwan Shree Rajneesh back in the 1970's, where they set up a commune in Oregon, USA, attracted a lot of very highly educated folks


People who are highly educated are not necessarily smart - they may be bookworms and they may even graduate with honor degrees with flying colors, but that does not, in any way, heighten the level of their intelligence at all

Submission + - Hands-On with Nvidia's New Card-Size 'SuperComputer' (hackaday.com)

szczys writes: Computer vision and machine learning have been tied to high-horsepower stationary machines. Nvidia's new credit-card-sized Jeston TX1 should bring a lot more processing power to embedded systems and is looking make these processor-heavy tasks portable. Brian Benchoff got his hands on one of the first review copies of the hardware and put it to the test. His take is that it's been designed to be driven very hard and lives up to they most of the hype Nvidia has been throwing around. It does currently require a carrier board but the connector can be source by experienced hardware designers and could be a viable choice for better autonomous systems.

Submission + - Will you be able to run a modern desktop environment in 2016 without systemd?

yeupou writes: Early this year, David Edmundson from KDE, concluded that "In many cases [systemd] allows us to throw away large amounts of code whilst at the same time providing a better user experience. Adding it [systemd] as an optional extra defeats the main benefit". A perfectly sensible explanation. But, then, one might wonder to which point KDE would remain usable without systemd?

Recently, on one Devuan box, I noticed that KDE power management (Powerdevil) no longer supported suspend and hibernate. Since pm-utils was still there, for a while, I resorted to call pm-suspend directly, hoping it would get fixed at some point. But it did not. So I wrote a report myself. I was not expecting much. But neither was I expecting it to be immediately marked as RESOLVED and DOWNSTREAM, with a comment accusing the "Debian fork" I'm using to "ripe out" systemd without "coming with any of the supported solutions Plasma provides". I searched beforehand about the issue so I knew that the problem also occurred on some other Debian-based systems and that the bug seemed entirely tied to upower, an upstream software used by Powerdevil. So if anything, at least this bug should have been marked as UPSTREAM.

While no one dares (yet) to claim to write software only for systemd based operating system, it is obvious that it is now getting quite hard to get support otherwise. At the same time, bricks that worked for years without now just get ruined, since, as pointed out by Edmunson, adding systemd as "optional extra defeats its main benefit". So, is it likely that we'll still have in 2016 a modern desktop environment, without recent regressions, running without systemd?

Submission + - Why Are Engineers More Likely to Become Terrorists? 1

HughPickens.com writes: Henry Farrel writes in the Washington Post that there's a group of people which appears to be highly prone to violent extremism — engineers — who are nine times more likely to be terrorists as you would expect by chance. In a forthcoming book, "Engineers of Jihad," published by Princeton University Press, Diego Gambetta and Steffen Hertog provide a new theory for why it is that engineers seem unusually prone to become involved in terrorist organizations. Gambetta and Hertog find strongly suggestive evidence that engineers are more likely to become terrorists because of the way that they think about the world. Survey data indicates that engineering faculty at universities are far more likely to be conservative than people with other degrees, and far more likely to be religious. They are seven times as likely to be both religious and conservative as social scientists. Gambetta and Hertog speculate that engineers combine these political predilections with a marked preference towards finding clearcut answers. This preference has affinities with the clear answer that radical Islamist groups propose for dealing with the complexities of modernity: Get rid of it.

Gambetta and Hertog suggest that this mindset combines with frustrated expectations in many Middle Eastern and North African countries, and among many migrant populations, where people with engineering backgrounds have difficulty in realizing their ambitions for good and socially valued jobs. This explains why there are relatively few radical Islamists with engineering backgrounds in Saudi Arabia (where they can easily find good employment) and why engineers were more prone to become left-wing radicals in Turkey and Iran.

Some people might argue that terrorist groups want to recruit engineers because engineers have valuable technical skills that might be helpful, such as in making bombs. This seems plausible – but it doesn’t seem to be true. Terrorist organizations don’t seem to recruit people because of their technical skills, but because they seem trustworthy and they don’t actually need many people with engineering skills. "Bomb-making and the technical stuff that is done in most groups is performed by very few people, so you don’t need, if you have a large group, 40 or 50 percent engineers," says Hertog. "You just need a few guys to put together the bombs. So the scale of the overrepresentation, especially in the larger groups is not easily explained."

How Computer Scientists Cracked a 50-Year-Old Math Problem (quantamagazine.org) 96

An anonymous reader writes: Over the decades, the Kadison-Singer problem had wormed its way into a dozen distant areas of mathematics and engineering, but no one seemed to be able to crack it. The question "defied the best efforts of some of the most talented mathematicians of the last 50 years," wrote Peter Casazza and Janet Tremain of the University of Missouri in Columbia, in a 2014 survey article.

As a computer scientist, Daniel Spielman knew little of quantum mechanics or the Kadison-Singer problem's allied mathematical field, called C*-algebras. But when Gil Kalai, whose main institution is the Hebrew University of Jerusalem, described one of the problem's many equivalent formulations, Spielman realized that he himself might be in the perfect position to solve it. "It seemed so natural, so central to the kinds of things I think about," he said. "I thought, 'I've got to be able to prove that.'" He guessed that the problem might take him a few weeks.

Instead, it took him five years. In 2013, working with his postdoc Adam Marcus, now at Princeton University, and his graduate student Nikhil Srivastava, now at the University of California, Berkeley, Spielman finally succeeded. Word spread quickly through the mathematics community that one of the paramount problems in C*-algebras and a host of other fields had been solved by three outsiders — computer scientists who had barely a nodding acquaintance with the disciplines at the heart of the problem.


2015 'Dance Your PhD' Winner Announced (sciencemag.org) 18

sciencehabit writes: Jargon seems unavoidable in science. When you try to explain your work, it becomes a minefield of technical concepts and abstract reasoning. But what if we just want the gist of what you do, the essence of your research? Oh, and make it a dance. The results are in from Science magazine's annual 'Dance Your PhD' contest. The winners include a ballet about a protein, a tango about entangled photons, a Bollywood spectacle about the immune system and, this year's top prize-winner, a dance by Florence Metz of the University of Bern, Switzerland, who combined hip hop, salsa, and acro-yoga to explain her PhD on the intricacies of water protection policies. She goes home with $1000 and a trip to Stanford University in the spring to screen her PhD dance and give a talk — hopefully jargon-free.

Hospitals Can 3D Print a Patient's Vasculature For Aneurysm Pre-Op Practice (computerworld.com) 21

Lucas123 writes: University of Buffalo physicians and researchers from two institutes working with 3D printer maker Stratasys have successfully 3D-printed anatomically correct models of patients' vascular systems — from their femoral artery to their brain — in order to test various surgical techniques prior to an actual operation. The new 3D printed models not only precisely replicate blood vessels' geometry, but the texture and tissue tension, allowing surgeons a realistic preoperative experience when using catheterization techniques. The printed models are also being used by physicians in training.

Lori Garver Claims That NASA Is 'Wary' of Elon Musk's Mars Plans (arstechnica.com) 103

MarkWhittington writes: Ars Technica reports that former NASA Deputy Administrator Lori Garver claimed, during a panel discussion at the Council for Foreign Relations, that many at NASA are "wary" of the Mars ambitions of SpaceX's Elon Musk. While the space agency has yielded low Earth operations to the commercial sector as part of the commercial crew program, it reserves for itself deep space exploration. Garver herself disagrees with that sentiment: "I thought, fundamentally, you just don’t understand. We’re not in a race in a swimming pool where everyone is racing against one another. We're in a cycling race where the government is riding point and the others are drafting behind us, and if someone comes alongside us and can pass us because they’ve found a better way, we don’t get out our tire pump and stick it between their spokes."

Gene Drive Turns Mosquitoes Into Malaria Fighters (sciencemag.org) 68

sciencehabit writes: The war against malaria has a new ally: a controversial technology for spreading genes throughout a population of animals. Researchers report today that they have harnessed a so-called gene drive to efficiently endow mosquitoes with genes that should make them immune to the malaria parasite—and unable to spread it. On its own, gene drive won't get rid of malaria, but if successfully applied in the wild the method could help wipe out the disease, at least in some corners of the world. The approach "can bring us to zero [cases]," says Nora Besansky, a geneticist at the University of Notre Dame in South Bend, Indiana, who specializes in malaria-carrying mosquitoes. "The mosquitoes do their own work [and] reach places we can't afford to go or get to."
