The New New Math of String Theory

At the beginning of the last century, Albert Einstein posited a now famous theory that forever linked geometry and fundamental physics. According to general relativity, spacetime is curved, and that curvature affects the ...

Evidence for ultra-energetic particles in jet from black hole

An international team of astronomers led by researchers at Yale has obtained key infrared observations that reveal the nature of quasar particle jets that originate just outside super-massive black holes at the center of ...

Seismic shock absorbers for woodframe houses

As part of a major international project to design more earthquake-resistant woodframe buildings, an engineer from Rensselaer Polytechnic Institute will be testing a damping system designed to act as a seismic shock absorber. ...

Finding a short circuit before it finds you

A preemptive spark lasting for nanoseconds that helps find potentially dangerous short circuits hidden in the miles of wiring behind the panels of aging commercial airliners has been patented by Sandia National Laboratories.

Human activities can affect rainfall

U.S. researchers say they've determined human activities in arid urban environments can affect the rainfall and water cycle.

Researchers Set Speed Record for Silicon-Based Chips

A research team from IBM and the Georgia Institute of Technology has demonstrated the first silicon-germanium transistor able to operate at frequencies above 500 GHz. Though the record performance was attained at extremely ...
