Scientists are exploring the power of radio waves to control fusion reactions

Physicist Eduardo Rodriguez with paper pictures. Photo credit: Elle Starkman. A key challenge in capturing and controlling fusion energy on Earth is to maintain the stability of the plasma – the electrically charged gas that drives the fusion reactions – and to keep it hot for millions of degrees to start and maintain fusion reactions. This challenge requires control of …

What are gravitational waves? | Basics of astronomy

-> Researchers at the Laser Interferometer Gravitational Wave Observatory (LIGO) recorded gravitational waves for the first time on September 14, 2015. Here a technician is working on some optics for a LIGO detector. Image via LIGO. Gravitational waves are waves in the structure of space-time. Just as a ship that travels across the surface of a calm sea leaves a …

Many beaches in Southern California remain closed due to heat waves

The ongoing closings have prompted local officials to remind the public to stay at home despite the temptation to hit the sand in summer weather. In Los Angeles County, the Home Stay Ordinance states that all public beaches, piers, public beach parking, and beach access points remain closed. The closings could cause Southern Californians to drive to Ventura and Orange, …

Machine translates brain waves into sentences

Image rights SPL Image description Brain activity was fed into a computer system that recognized recurring features in the data Scientists have taken a step forward to decipher what a person says by only looking at their brainwaves when they speak. They trained algorithms to translate brain patterns into sentences in real time with word error rates as low as …

Trey Edward Shults swings Waves to the emotional fences

Nobody should accuse Trey Edward Shults of giving less than 110%. His third feature film, Waves gives the impression of an aspiring independent who uses the confidence of the youth to shoot a masterpiece. Shults wants to make his Boogie Nights with the off-the-wall camera work and the big pinpricks and soul-deep emotionality that the comparison implies. Each scene seems …

Heat waves could increase significantly by mid-century, according to a new study

Credit: CC0 Public Domain Our planet baked under the sun this summer as temperatures reached the hottest ever measured and heat waves spread across the globe. As the climate continues to warm, scientists expect an increase in the frequency and intensity of heat waves. A frequently overlooked aspect, however, is the spatial size of the heatwaves, despite their important implications. …

Underground detector in Japan to search for gravitational waves

Illustration of the underground KAGRA detector. Illustration : ICRR, Univ. from Tokyo. A fourth gravitational wave detector, this one in Gifu Prefecture Japan, will join this December's global search for cosmic events causing waves in space-time. The Kamioka gravitational wave detector -Wave Detector (KAGRA) is in the commissioning phase according to a press release and will link the two LIGO …

The "ringing" of the black hole emitting gravitational waves supports Einstein's Theory of Relativity

The "ringing" of the black hole, which emitted weak gravitational wave tones after the merger, supports Einstein's theory of relativity even more. Researchers have discovered sounds that emanate from a black hole. The discovery confirms a theory by Albert Einstein from 100 years ago The merging of black holes emits gravitational waves that reverberate at certain sounds. The waves could …
