Scientists Measure Magnetic Interaction Between Two Bound Electrons 26

Posted by Soulskill from the less-than-fridge-magnets dept.
An anonymous reader writes In a paper published in Nature (abstract), scientists report successfully measuring the magnetic interaction of two bound electrons of two different strontium (Sr) ions. The two ions were suspended in a quadrupole ion trap (a.k.a. a Paul trap), and the effects of ambient magnetic noise were mitigated by 'restricting the spin evolution [of the electrons] to a decoherence-free subspace that is immune to collective magnetic field noise.' The scientists measured the magnetic interaction of the two electrons as a function of distance and found that the force acting between the two was inversely dependant on the cubed distance between the electrons, consistent with Newton's inverse-cube law.

Submission + - Massive change to Windows 9 - strip out Metro? (winbeta.org)

Submitted by bricko
bricko writes: The Chinese Government infamously announced recently that they have banned the use of Windows 8 and Windows 8.1 on Government PC's due to the cloud/Modern UI integration. While it may not sound like a big deal on the surface, Microsoft are currently panicking regarding the whole ordeal, and are currently reconsidering a number of plans with Windows 9.

Microsoft has already made drastic changes to the way employees at Microsoft access test builds. Instead of the builds being freely accessible via Microsoft CorpNet, an employee is required to request a new build which is personally assigned to them, this change will attempt to minimize leaks dramatically.

According to WZOR, Windows 9 Enterprise Edition could potentially see the removal of cloud-based integration within the operating system, along with the ability to completely disable the Modern UI 2.0.

Microscopic View of How Leaves Repel Water 33

Posted by Soulskill from the make-like-a-tree-and-get-outta-here dept.
An anonymous reader writes: Years of research has gone into products that are hydrophobic — they resist getting wet. But nature solved this problem long ago, and it's ubiquitous outside our buildings and homes. You've probably seen it yourself, after a light rain: water collects in round droplets on many leaves from trees and plants, refusing to spread out evenly across the surface. This article explains why that happens using super slow-mo cameras and an electron microscope. "[T]he water isn't really sitting on the surface. A superhydrophobic surface is a little like a bed of nails. The nails touch the water, but there are gaps in between them. So there's fewer points of contact, which means the surface can't tug on the water as much, and so the drop stays round. ... [After looking at a leaf in the electron microscope,] we saw this field of tiny wax needles, each needle just a few microns in length! The water drops are suspended on these ultra-microscopic wax needles, and that keeps it from wetting the surface."

BlackBerry Back In Profit 67

Posted by Soulskill from the bouncing-back dept.
An anonymous reader sends word that BlackBerry, hit hard over the past several years by the emergence of smart phones, has come back to profitability. BlackBerry has been fighting an uphill battle to stay relevant in the world of mobile devices. It has lost market share to Apple, companies like Samsung that offer gadgets running on Google's Android operating system, and Microsoft. But John Chen, who took over as CEO in November, has injected new life to the company. Chen, who says BlackBerry is getting close to breaking even on its hardware business, has steered the company's focus more towards software. He's made several product announcements that Wall Street has cheered. Last month, the company launched its Project Ion, an initiative to develop more connected devices ... a trend dubbed the Internet of Things. On Wednesday, BlackBerry reached a deal with Amazon that will let users of BlackBerry's newest operating system access Android apps in Amazon's appstore later this fall.

Submission + - Age discrimination in the tech industry

Submitted by Presto Vivace
Presto Vivace writes: Tech industry job ads: Older workers need not apply

It’s a widely accepted reality within the technology industry that youth rules. But at least part of the extreme age imbalance can be traced back to advertisements for open positions that government regulators say may illegally discriminate against older applicants. Many tech companies post openings exclusively for new or recent college graduates, a pool of candidates that is overwhelmingly in its early twenties. ...

“In our view, it’s illegal,” Raymond Peeler, senior attorney advisor at the Equal Employment Opportunity Commission, the federal agency that enforces workplace discrimination laws said about the use of “new grad” and “recent grad” in job notices. “We think it deters older applicants from applying.”

Am I the only one who thinks that much of the quality control and failed projects in the tech industry can be attributed to age discrimination?

First Movie of an Entire Brain's Neuronal Activity 44

Posted by timothy from the may-not-be-suitable-for-children dept.
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."

Ask Slashdot: How To Bequeath Sensitive Information? 208

Posted by timothy from the and-to-my-terrrible-son-william dept.
New submitter UrsaMajor987 (3604759) writes I recently retired after a long career in IT. I am not ready to kick the bucket quite yet, but having seen the difficulty created by people dying without a will and documenting what they have and where it is, I am busy doing just that. At the end of it all, I will have documentation on financial accounts, passwords, etc., which I will want to share with a few people who are pretty far away. I can always print a copy and have it delivered to them, but is there any way to share this sort of information electronically? There are lots of things to secure transmission of data, but once it arrives on the recipients' desktop, you run the risk of their system being compromised and exposing the data. Does anyone have any suggestions? Is paper still the most secure way to go?

Bitcoin Security Endangered By Powerful Mining Pool 281

Posted by timothy from the cornering-the-market dept.
An anonymous reader writes Ars Technica reports that for the first time in Bitcoin's five-year history, a single entity has repeatedly provided more than half of the total computational power required to mine new digital coins, in some cases for sustained periods of time. It's an event that, if it persists, signals the end of crypto currency's decentralized structure."

How To Make Espresso In Space 192

Posted by timothy from the they-finally-saw-airplane-II dept.
In a story that's sure to bring to the surface the long-debunked myth of an over-elaborate NASA quest to create a pen to operate in space, Wired reports that the coffee situation aboard the International Space Station is about to improve: the station will be getting a 20kg, custom designed Lavazza espresso machine, to be delivered along with Italian astronaut Samantha Cristoforetti. Among other differences from terrestrial espresso machines: the resulting beverage must be pumped into a straw-friendly bag rather than a demitasse. I wonder if there could be some way to adapt a (much lighter) Aeropress for space purposes, as a backup.
