Flaring Stars May be the Cause of Mysterious ‘Fast Radio Bursts’

First discovered in 2007, "fast radio bursts" continue to defy explanation. These cosmic chirps last for only a thousandth of a second. The characteristics of the radio pulses suggested that they came from galaxies billions of light-years away. However, new work points to a much closer origin - flaring stars within our own galaxy.

In the Presence of a Magnetic Field, Negative Resistivity Can Produce Positive Resistance

In a paper appearing in Nature's Scientific Reports, Dr. Ramesh Mani, professor of physics and astronomy at Georgia State University, reports that, in the presence of a magnetic field, negative resistivity can produce a positive resistance, along with a sign reversal in the Hall effect, in GaAs/AlGaAs semiconductor devices.

Near Broken-Gap TFET Utilizes Quantum Mechanical Tunneling of Electrons to Provide High Current at Low Voltage

Penn State researchers have proved the feasibility of a new type of transistor that could make possible fast and low-power computing devices for energy constrained applications such as smart sensor networks, implantable medical electronics, and ultra-mobile computing. Called a near broken-gap tunnel field effect transistor (TFET), the new device uses the quantum mechanical tunneling of electrons through an ultrathin energy barrier to provide high current at low voltage.

Astronomers Capture Never-Before-Seen Details of Starburst Galaxy

Using the new, high-frequency capabilities of the National Science Foundation’s Robert C. Byrd Green Bank Telescope (GBT), astronomers have captured never-before-seen details of the nearby starburst galaxy M82. These new data highlight streamers of material fleeing the disk of the galaxy as well as concentrations of dense molecular gas surrounding pockets of intense star formation.

Time Travelers Could Possibly Copy Quantum Data from the Past

Popular television shows such as "Doctor Who" have brought the idea of time travel into the vernacular of popular culture. But problem of time travel is even more complicated than one might think. LSU's Mark Wilde has shown that it would theoretically be possible for time travelers to copy quantum data from the past.

Smaller Particle Impacts May be Serving up Miniscule Drops of Hot Quark-Gluon Plasma

Scientists designed and built the Relativistic Heavy Ion Collider (RHIC) at the U.S. Department of Energy’s Brookhaven National Laboratory to create and study a form of matter that last existed a fraction of a second after the Big Bang, some 13.8 billion years ago. The early-universe matter is created when two beams of gold nuclei traveling close to the speed of light slam into one another.
