KERA: Bitcoin — Behind The Cryptocurrency Curtain

Bitcoin, KERA, Tyler Moore, SMU, ponzi schemeKERA Public Radio journalist Justin Martin tapped the expertise of SMU Bitcoin and cybersecurity expert Tyler W. Moore, an assistant professor of computer science in the Lyle School of Engineering.

An expert on the digital currency Bitcoin, Moore’s expertise draws in part on his research surrounding Bitcoin, the exchanges that trade in the currency and patterns of online usage. One of Moore’s studies found that online money exchanges that trade hard currency for the rapidly emerging cyber money have a 45 percent chance of failing — often taking their customers’ money with them.

Hunt begins for elusive neutrino particle at one of the world’s largest, most powerful detectors

NOvA, SMU, Thomas Coan, Fermilab, neutrinosWhen scientists pour 3.0 million gallons of mineral oil into what are essentially 350,000 giant plastic tubes, the possibility of a leak can’t be overlooked, says SMU physicist Thomas E. Coan.

The oil and tubes are part of the integral structure of the world’s newest experiment to understand neutrinos — invisible fundamental particles so abundant they constantly bombard us and pass through us at a rate of more than 100,000 billion particles a second. Continue reading
