Climate models overestimate natural variability

By looking at satellite measurements of temperature changes in the lower layer of Earth's atmosphere, scientists found that climate models may have overestimated the decade-to-decade natural variability of temperature.

A technique to sift out the universe's first gravitational waves

In the moments immediately following the Big Bang, the very first gravitational waves rang out. The product of quantum fluctuations in the new soup of primordial matter, these earliest ripples through the fabric of space-time ...

Custom fabricated microscope lens inspired by lighthouse

An optical device that resembles a miniaturized lighthouse lens can make it easier to peer into Petri dishes and observe molecular-level details of biological processes, including cancer cell growth. Developed by KAUST, the ...

What happened before the Big Bang?

A team of scientists has proposed a powerful new test for inflation, the theory that the universe dramatically expanded in size in a fleeting fraction of a second right after the Big Bang. Their goal is to give insight into ...

New detector fails to confirm would-be evidence of dark matter

Almost 20 years ago, the DAMA/LIBRA experiment at Italy's Gran Sasso National Laboratory—LNGS began publishing data showing that it had detected a signal modulation produced by an interaction with the Milky Way's dark ...

Creative use of noise brings bio-inspired electronic improvement

In conventional electronics, a great deal of effort is devoted to eliminating stochastic resonance (SR)—the annoying hiss that generally hinders the detection of weak signals and degrades overall device performance. But, ...
