“Hello? Who’s calling?” For many Americans these days, the call is coming from a “bot” or automated program that seeks to trick them into giving up money or important personal data.

The scourge of “robocalls” by the billions has prompted US regulators to adopt new rules allowing carriers to implement tools to block calls with suspicious origins.

The automated calls may tell respondents that they owe back taxes or other bills that need to be settled immediately, or direct them to call numbers where they are charged for the connection.

A key obstacle to controlling on Earth the fusion that powers the sun and stars is leakage of energy and particles from plasma, the hot, charged state of matter composed of free electrons and atomic nuclei that fuels fusion reactions. At the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), physicists have been focusing on validating computer simulations that forecast energy losses caused by turbulent transport during fusion experiments.

Researchers used codes developed at General Atomics (GA) in San Diego to compare theoretical predictions of electron and ion turbulent transport with findings of the first campaign of the laboratory’s compact—or “low-aspect ratio”—National Spherical Torus Experiment-Upgrade (NSTX-U). GA, which operates the DIII-D National Fusion Facility for the DOE, has developed codes well-suited for this purpose.

Low-aspect ratio tokamaks are shaped like cored apples, unlike the more widely used conventional tokamaks that are shaped like doughnuts.

Who are you really talking to?


AT&T Labs will begin selling speech software it says is so good at reproducing sounds, inflections and intonations of human voice, that it can recreate voices and even bring those of long-dead celebrities back to life; Natural Voices software, which turns printed text into synthesized speech, makes it possible for company to use recording of person’s voice to utter things person never actually said; utterances still contain few robotic tones and unnatural inflections, leading competitors to question whether it is substantial step up from existing products; tests suggest it may be first text-to-speech software to raise specter of voice cloning, replicating person’s voice so perfectly that human ear cannot tell difference; photo (M)

On March 14, 2012, MINERνA submitted a preprint demonstrating communication using neutrinos. Though not a part of the experiment’s physics program, this is the first reported instance of a message being transmitted by neutrinos. Scientists used ASCII code to represent the word “neutrino” as a series of 1s and 0s. Over a period of 6 minutes, this sequence was delivered by either the presence or absence of a neutrino pulse, over a distance of about a kilometer.

Main Injector Experiment for ƒË-A, or MINERνA, is a neutrino scattering experiment which uses the NuMI beamline at Fermilab. MINERνA seeks to measure low energy neutrino interactions both in support of neutrino oscillation experiments and also to study the strong dynamics of the nucleon and nucleus that affect these interactions.
