Want To Fight Climate Change? Stop Cows From Burping 40 40

sciencehabit writes: A simple supplement to a cow's feed could substantially decrease a major source of methane, a planet-warming greenhouse gas, a new study suggests. Each year worldwide, the methane produced by cud-chewing livestock warms Earth's climate by the same amount as 2.1 billion tons of carbon dioxide, a little more than 4% of the greenhouse gas emissions related to human activity. That makes cows tempting targets for methane reduction efforts. In a new study, researchers added the chemical 3-nitrooxypropanol, also known as 3NOP, to the corn-and-alfalfa-based feed of 84 milk-producing Holsteins and monitored their methane production for 12 weeks—the largest and longest such trial of its type in lactating cows, the scientists say. For cows whose feed included 3NOP, methane emissions dropped, on average, by 30%.

Submission + - Unicode consortium looks at symbols for allergies

AmiMoJo writes: A new preliminary proposal submitted to the Unicode Consortium suggests that specific emoji for food allergies should be added to the standard. The proposal (PDF), submitted by a Google engineer, is under discussion and may not be added to the standard at all but offers a peek into some useful new emoji. It suggests the addition of peanuts, soybeans, buckwheat, sesame seeds, kiwi fruit, celery, lupin beans, mustard, tree nuts, eggs, milk products and gluten to help those with allergies express them in shorthand.

Submission + - New telemetry suggests shot-down drone was higher than alleged

AmiMoJo writes: The pilot of the drone shot down Sunday evening over a Kentucky property has now come forward with video seemingly showing that the drone wasn't nearly as close as the property owner made it out to be. The data also shows that it was well over 200 feet above the ground before the fatal shots fired. The shooter, meanwhile, continues to maintain that the drone flew 20 feet over a neighbour's house before ascending to "60 to 80 [feet] above me."

Submission + - can a blind programmer use modelling projects visual studio->

StarTrekCafe writes: hi. can blind people use accessible modelling tools for visual studio? probably not! as screen readers cannot read text inside images or graphics or diagrams. so i need to do a modelling project for my programming course via http://www.upskilled.edu.au./ I use a screen reader Jaws For Windows from http://www.freedomscientific.c... Now, what are my options. Did try plant uml, but that is java based. So any ideas, need to do state, use, case, class and sequence diagrams from a couple of projects i have done already. A C# and a SQL Database project. Will ryno 3d do the job with accessibility? So what accessible tools, can i use? need to convey this information to my lectuer. Will it read the content in visual studio 2013 or 2015?

Solar-Powered Flight For 81 Hours: a New Endurance World Record 18 18

Hallie Siegel writes: A team of researchers from ETH Zurich have just set a new endurance record for solar powered flight of an unmanned autonomous aircraft, achieving over four days of solar-powered flight in a range of weather conditions. Being able to demonstrate more than 24 hours of endurance is important because overcast skies can inhibit recharging and poor weather or high winds can effect power consumption. Nice achievement for this class of aircraft.

Submission + - Non-invasive spinal cord stimulation gets paralyzed legs moving again->

schwit1 writes: Five men with complete motor paralysis have regained the ability to move their legs voluntarily and produce step-like movements after being treated with a non-invasive form of spinal cord stimulation. The new treatment builds on prior work to generate voluntary movements in paralyzed people through electrical stimulation â" in particular, two studies (one completed in 2011, the other in 2014) that involved surgically implanting an electrode array on the spinal cord. This time, however, the researchers found success without performing any invasive surgery.

The new treatment uses a technique called transcutaneous electrical nerve stimulation, which involves strategically placing electrodes on the skin of the lower back. While receiving stimulation, the men's legs were supported by braces that hung from the ceiling. At first their legs only moved involuntarily, if at all. But they soon found they could voluntarily extend the distance their legs moved during stimulation. They doubled their range of voluntary motion after four treatment sessions.

Submission + - FireChat Weaves Smartphones Into an Alternative Internet->

schwit1 writes: What do people in Manila watching the Pope give Mass, Russian and Hong Kong protesters, and U.S. festivalgoers have in common? They have all turned to FireChat, an app that creates hyperlocal chat rooms that work even when cell networks are down by connecting phones within Wi-Fi range of one another (see "The Latest Chat App for the iPhone Needs No Internet Connection").

An upgrade to FireChat released today could make the app much more useful and powerful. It makes it possible to communicate with other FireChat users beyond the roughly 70 meters that your device can reach with Wi-Fi. Private and public messages can now travel longer distances by hopping between FireChat users until they get to the intended recipient-an approach known as mesh networking. Messages are encrypted as they travel through intermediate devices.

Comment BitLocker is Ultimate-only and Ultimate is gone (Score 1) 225 225

Windows Professional didn't start to include BitLocker until Windows 8. You need Windows 7 Ultimate for that, and that was withdrawn from inclusion with PCs along with Windows 7 Home Premium. Is Anytime Upgrade from Windows 7 Professional to Windows 7 Ultimate still in operation?

Comment #NotAllCops know what they're talking about (Score 1) 147 147

And sometimes you get law enforcement officers who appear to have forgotten the rules of the road. Today I was in the right half of the through lane of a city street without a bike lane, with a right-turn-only lane (we drive on the right in the United States) to my right. A cop in a cop car pulled up beside me at a red light and told me I shouldn't be on the road because I'm blocking traffic. When I asked for clarification, he told me I ought to be farther to the right or on the sidewalk, and then he drove off. As far as I can tell, the first is illegal because the lane to the right is a turn-only lane, and the second is dangerous because it might cause me to plow into a pedestrian. Was this an attempted entrapment or just what the French call les incompetents?

One In Four Indiana Residents' E-Record Data Exposed in Hack 45 45

Reader chicksdaddy reports that a data breach involving four million patients and more than 230 different data holders (from private practices to large hospitals) hit Indiana especially hard. It's the home state of Medical Informatics Engineering, maker of electronic records system NoMoreClipBoard. While data exposed in the breach affected 3.9 million people, 1.5 millon of them are in Indiana. According to the Security Ledger, though: [The] breach affects healthcare organizations from across the country, with healthcare providers ranging from prominent hospitals to individual physicians' offices and clinics are among 195 customers of the NoMoreClipboard product that had patient information exposed in the breach. And, more than a month after the breach was discovered, some healthcare organizations whose patients were affected are still waiting for data from EMI on how many and which patients had information exposed.

'We have received no information from MIE regarding that,' said a spokeswoman for Fort Wayne Radiology Association (http://www.fwradiology.com/), one of hundreds of healthcare organizations whose information was compromised in the attack on MIE..
