New mapping tool tracks elk migration to reduce brucellosis risk
Wildlife managers and ranchers in the greater Yellowstone ecosystem soon will have a new mapping tool for reducing the risk of brucellosis outbreaks in cattle. The team of biologists built a computer model of elk behavior during spring migration to identify habitats with the highest risk of brucellosis spilling over from elk to cattle. Brucellosis is a bacterial disease carried by elk and bison that can cause pregnant females to abort their fetuses.
Hundreds of Mysterious Stone 'Gates' Found in Saudi Arabia's Desert
Each looks like a child's kite, complete with strings and long fluttering tails that are two-dimensionally flattened into the ground. The structure's two long converging walls would funnel stampedes of gazelles into the body of the kite, where they would be slaughtered. The lava fields extend beyond Jordan's borders into countries like Syria and Saudi Arabia. Saudi Arabia in particular offers a wealth of harrats that are just out of Dr Kennedy's reach.
Native American Secrets Lie Buried in Huge Shell Mounds
From about 2,200 to 800 years ago, Native Americans visited this site in late winter and spring. They were eating oysters like crazy and catching alewives, Dr Spiess said, referring to a type of herring. This and other middens have revealed much of what is known about Native Americans in Maine over the past 4,000 years. Ms Miller said in addition to the cultural information buried in the middens, the shells are also a record of ancient climate.
Dogs Pay Attention to Your Looks
Sometimes a dog's expression merely reflects yours. In a new study, researchers in Britain monitored dogs' facial expressions - particularly the muscle that raises the inner part of the eyebrows and makes their eyes look bigger - while a person was either paying attention to them or turned away, sometimes holding food and sometimes not.
The NRA Wants Gun Owners To Carry Everywhere. Here's Why They Shouldn't.
In some states, law enforcement can deny a permit if they believe the applicant lacks good character, or doesn't have a good reason to carry a loaded gun in public. They found that shall-issue states were associated with 8.6 percent higher firearm homicide rates and 10.6 percent higher handgun homicide rates. It would force states to allow people to carry concealed weapons who normally, under that state law, may not have access to one.
Your Dog Making A 'Sad Puppy Face' May Be Trying To Tell You Something
It might seem pretty obvious to dog lovers, but researchers have found scientific evidence suggesting that dogs use facial expressions intentionally to communicate with humans. To gain some insight, researchers with the University of Portsmouth in England enlisted 24 dogs of varying ages and breeds. In particular, dogs were more likely to show their tongues in a relaxed fashion and to make an expression many people think of as a sad puppy face, which dogs make by raising their inner eyebrows.
The future is here: Augmented reality apps to use on your iPhone or iPad
With the release of an updated mobile operating system earlier this month, Apple's new augmented reality platform is ready for take-off. With iOS 11, anyone with an iPhone 6 or more current device or an iPad Pro first generation can play around with augmented reality. Here's a look at some of the best ways to experiment with augmented reality on your iPhone or iPad.
NASA sees intensifying Typhoon Lan stretch high in the troposphere
NASA's Global Precipitation Measurement mission or GPM satellite provided 3-D data that showed intensifying Typhoon Lan had powerful thunderstorms stretching high into the troposphere. NASA-NOAA's Suomi NPP satellite provided a visible image Typhoon Lan that showed the well-developed circulation. Tropical Storm Lan recently moved toward the north and was upgraded to Typhoon Lan. GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) instruments collected data that were used in this examination of Typhoon Lan's rainfall.
Bobak Ferdosi: We Are Far More Similar Than Different
Our latest interviewee is Bobak Ferdosi. Bobak Ferdowsi is the Fault Protection lead on the NISAR joint Earth observation mission with India at NASA's Jet Propulsion Laboratory. Bobak has always wanted to find life elsewhere in our universe. I was raised by my Iranian dad and American mother in the East Bay Area in California. I'm not sure I'm really successful yet, but I think it's mostly been trying to improve myself both personally and professionally.
Physicists gain understanding of how bubbles at the edge of plasmas can drain heat and reduce fusion reaction efficiency
To fuse hydrogen atoms into helium, doughnut-shaped devices called tokamaks must maintain the heat of the ultrahot plasma they control. This ability produces a more fundamental and fuller picture of how heat moves from plasma to the walls, potentially causing damage. Simulations of turbulence at the edge of the plasma, near where the plasma approaches a tokamak's interior wall, are particularly important.
Using optical chaos to control the momentum of light
One major hurdle is that light travels at different speeds and in different phases in different components of an integrated circuit. For light to couple between optical components, it needs to be moving at the same momentum. Previously, researchers need multiple special optical elements to couple light in and out WGMs at different wavelengths, but by this work we can couple all color lights with a single optical coupler.
New tyrannosaur fossil is most complete found in southwestern US
We are eager to get a closer look at this fossil to learn more about the southern tyrannosaur's anatomy, biology, and evolution. GSENM Paleontologist Dr Alan Titus discovered the fossil in July 2015 in the Kaiparowits Formation, part of the central plateau region of the monument. Particularly notable is that the fossil includes a nearly complete skull. Scientists hypothesize that this tyrannosaur was buried either in a river channel or by a flooding event on the floodplain, keeping the skeleton intact.
Iridium to rely on used SpaceX boosters for next two launches
Iridium Communications says its next two launches of new-generation satellites will use refurbished SpaceX Falcon 9 first-stage boosters that have flown previously. The company has launched a few used boosters and is trying to expand acceptance of reusability across the industry. Hawthorne, California-based SpaceX has had successful landings of Falcon 9 first stages after launches from both coasts. Iridium is in the midst of seven launches to replace its satellite fleet that provides global mobile voice and data communications.
Lyft gets $1 bn from Google parent to rev up challenge to Uber
US ridesharing giant Lyft announced Thursday it has received a $1 billion investment led by the venture arm of Google parent Alphabet, to help ramp up its challenge to market leader Uber. A Lyft blog post said the new funding round was led by CapitalG, formerly known as Google Capital, which invests in emerging tech firms. Lyft has been expanding in the US market as Uber's image has taken a hit in recent months.
Missouri proposes innovation corridor for Amazon's 2nd home
Missouri officials were submitting a bid Thursday for Amazon's second headquarters that would involve an innovation corridor between Kansas City and St Louis rather than a single location in one of the state's major metropolitan areas. Amazon in September opened the search for a second headquarters and promised to spend more than $5 billion on the site. Missouri Chief Operating Officer Drew Erdmann said the state's bid could be aided if it succeeds in landing a high-speed Hyperloop track connecting the cities.
G7 to put squeeze on internet giants at terror talks
Tech giants including Google, Facebook and Twitter will come under pressure in Italy this week to go further and faster in helping G7 powers tackle the ever-greater threat of extremists online. Over 80 percent of conversations and radicalisation happen online, said Italy's Marco Minniti, who is hosting the summit on the volcanic island off Naples. Tough privacy laws and protections enjoyed by the largely US-based web giants are impeding authorities, they said.
Dutch family sells everything to bet on bitcoins
We are putting everything into bitcoin, we've sold everything to invest in this currency, Didi Taihuttu told AFP. Bitcoins can be exchanged for goods and services-or for other currencies-provided the other party is willing to accept them. Taihuttu and his family have already invested tens of thousands of euros and the money from the sale of their house will be added to it. Should things go wrong however, he and his family will just go back to square one.
Coming soon: a selfie with your credit card application
Facebook, Instagram, Twitter-and soon your bank could be asking for one in order to approve your purchase or credit card application. Payment processing giant Visa is launching a platform to allow banks to integrate various types of biometrics-your fingerprint, face, voice, etc-into approving credit card applications and payments. If a person were to apply for a credit card application on their smartphone, the bank app could ask the applicant to take a selfie and then take a picture of a driver's license or passport.
Workers at iPhone supplier in China protest unpaid bonuses
The protest Wednesday night at Jabil Inc.'s Green Point factory in Wuxi city prompted Apple to launch an investigation and vow to redress the payment discrepancies. Apple stepped up oversight and disclosure following a spate of negative reports about worker suicides and injuries at suppliers. Apple said it did comprehensive audits of 705 sites last year and documented significant improvements in compliance with its supplier code of conduct.
Computer tutor gives students the skills to dream bigger
Delray Beach resident Falon Velez would like to see more little girls dreaming of designing cars instead of playing dress-up with Barbies. Students learn (computer-aided design) programs and 3-D printing and make some amazing designs. Velez said she was dazzled by a unique plant pot design one of her youngest students came up with. One of my students designed a pot on SketchUp to bring to her friend in Norway, Velez said.
