Physicists successfully map individual atoms in 3D

Technology can evolve at such a rapid rate that many scientific discoveries are not just pushing boundaries, they’re practically barging them. Example, Physicists at UCLA have managed to 3D-map the position of individual atoms to a precision of 19 trillionths of a meter (that’s several times smaller than a hydrogen atom, for those of you playing at home) using a creative scanning technique. The method will help scientists and engineers build things — such as aircraft components — that lack point defects (i.e. missing atoms) that can have detrimental effects on structural integrity. The new procedure is called “scanning transmission electron microscopy” and works by passing an electron beam over a sample and measuring how many electrons interact with the atoms in said sample. Different arrangements of atoms react with the electrons in different ways so the outcome is unique to a particular atomic structure. The team conducts the initial scan which produces a 2D image, and in order to get to the final 3D product, they combine several scans from different angles. The downside of this technique is that multiple scans can potentiality damage the sample. The research is led by Jianwei (John) Miao, a UCLA professor of physics. Currently, a method known as X-Ray crystallography is used to map the layout of billions of atoms at a time, but has never been able to pinpoint an atom’s exact coordinates. This all encompassing procedure makes identifying a missing atom impossible. “Our measurements are so precise, and any vibrations — like a person walking by — can affect what we measure, ” said Peter Ercius, a staff scientist at Lawrence Berkeley National Laboratory. The team of UCLA scientists who happened across this discovery now plan to use it in order to study magnetic properties. [Image Credit: Mary Scott and Jianwei (John) Miao/UCLA] Source: UCLA Newsroom

BT promises 300Mbps broadband for 10 million homes by 2020

BT’s chief executive Gavin Patterson has emerged today with a laundry list of promises designed to improve broadband speeds, coverage and public confidence in the UK. First up is a commitment to a new, minimum broadband speed of 5-10Mbps, which the company claims will be enough for people to “enjoy popular internet services like high definition video.” The idea to push for a minimum standard was actually introduced by the UK government earlier this year . BT’s involvement is a crucial statement of support, although at the moment there’s no timeframe as to when it’ll be introduced or even feasible. There’s also the matter of the speeds themselves — 5Mbps, most would argue, isn’t enough to support a family or a group of flatmates that regularly use the internet simultaneously. To introduce such a proposal, Britain needs stable, extensive broadband coverage. The government’s current target is to offer 2Mbps to everyone in the UK and at least 24Mbps to 95 percent of the population by 2017. Patterson claims that BT will go “further and faster” in relation to these targets, however, through a funding mechanism called “success dividend” clauses. In short, some broadband infrastructure is currently funded by a mixture of BT, central government and local government money. If more customers than expected end up using this capacity, BT has to reinvest or return some of the funding — £130 million has already been released this way. Patterson says it’s now “potentially available” to increase the UK’s coverage target to 96 percent, although we’ll have to wait and see if that materialises. BT already has a plan to make it happen though — Patterson hinted at a new satellite broadband service that will launch this year and connect remote parts of the UK. All of this should create a broad base of usable, if not blazingly fast internet. At the other end of the spectrum, BT is trialling Fibre To The Distribution Point (FTTdp), commonly referred to as ” G.fast , ” which could jack up the slower speeds experienced by some existing customers. The company is aiming for “a few hundred megabits per second” initially, with plans to raise the speeds to 500Mbps over time. In January, it said this ultrafast broadband would be available to “most of the UK” within a decade . Now, Patterson is improving that target — he says the technology, along with some superior Fibre To The Premises (FTTP) provision, will connect 10 million homes and small businesses by 2020, before supplying “the majority” of UK premises by the end of the decade. These announcements come at a pivotal time for BT. The UK communications regulator Ofcom is in the middle of its ” Strategic Review of Digital Communications , ” the last of which forced BT to create Openreach, its broadband infrastructure division. The current review is looking at the two again, and whether they should be separated entirely — something BT, unsurprisingly, is keen to avoid. Sky, Vodafone, TalkTalk and others banded together only yesterday to argue that the review should be bumped up to the Competition and Markets Authority. It’s no secret that they want the pair split up , so BT is doing everything in its power to show that the current arrangement is still the best option for the UK. A heap of new promises to improve broadband provision is likely just the start of its fightback. [Image Credit: PjrTravel / Alamy] Source: BT

Volkswagen Could Face $18 Billion Fine Over Emission-Cheating Software

After getting caught cheating on emissions testing by means of software, Volkswagen could face up to $18 billion in fines, reports USA Today. That number is based on the company being assessed the maximum penalty of $37, 500 per affected vehicle. That’s not the only bad news for Volkswagen, which has halted sales of its 4-cylinder diesel cars; the linked article reports that the violations “could also invite charges of false marketing by regulators, a vehicle recall and payment to car owners, either voluntarily or through lawsuits. Volkswagen advertised the cars under the ‘Clean Diesel’ moniker. The state of California is also investigating the emissions violations.” Read more of this story at Slashdot.

Air Force fighters will carry Laser cannons, cyber weapons by 2020

An artist’s rendering of HELLADS, a General Atomics-built laser weapon now in ground testing. Air Force leaders say a laser pod based on the technology could be aboard fighter aircraft within five years. DARPA Sometime very soon, combat aircraft may be zapping threats out of the sky with laser weapons. “I believe we’ll have a directed energy pod we can put on a fighter plane very soon,” Air Force General Hawk Carlisle said at this week’s Air Force Association Air & Space conference in a presentation on what he called Fifth-Generation Warfare. “That day is a lot closer than I think a lot of people think it is.” Some low-power laser weapons were on display in mock-up on the exposition floor of the conference, including a system from General Atomics that could be mounted on unmanned aircraft such as the Predator and Reaper drones flown by the Air Force. But the Air Force is looking for something akin to a laser cannon for fighter aircraft, more powerful systems that could be mounted on fighters and other manned Air Force planes within the next five years, Air Force leaders said. Directed-energy weapons pods could be affixed to aircraft to destroy or disable incoming missiles, drones, and even enemy aircraft at a much lower “cost per shot” than missiles or even guns, Carlisle suggested. The Air Force isn’t alone in seeking directed energy weapons. The US Navy has already deployed a laser weapon at sea aboard the USS Ponce, capable of a range of attacks against small boats, drones, and light aircraft posing a threat—either by blinding their sensors or operators, or heating elements to make them fail or explode. Other laser weapons are also being tested by the Office of Naval Research for use on helicopters to protect against man-portable antiaircraft missiles. (And there’s a railgun , but that’s not really a directed=energy weapon, and it’s too massive to be mounted on an aircraft). Read 18 remaining paragraphs | Comments

Re-Analysis of Medical Study Reverses Conclusions — Paxil Unsafe For Teenagers

An anonymous reader writes: The NY Times is covering a new paper in the journal BMJ which re-analyzed data from a 2001 paper, coming to the opposite conclusions of the earlier study. The BMJ paper covers the effectiveness and safety of two antidepressant drugs for adolescent use, and the authors were able to re-analyze the original data after the release of previously confidential documents. The BMJ editors call into question some of the integrity of previous publishing, noting that none of the authors listed on 2001 paper actually wrote the original manuscript, and call for results of clinical trials to be made freely available so the science community can verify and self-correct results. The BMJ has released the study and provided an accompanying press release (PDF). Read more of this story at Slashdot.
