Seeing with radio waves
Scientists from the Division of Physics at the University of Tsukuba used the quantum effect called 'spin-locking' to significantly enhance the resolution when performing radio-frequency imaging of nitrogen-vacancy defects in diamond. This work may l.....»»
NASA"s deep space communications to laser boost
Set to launch this fall, NASA's Deep Space Optical Communications (DSOC) project will test how lasers could speed up data transmission far beyond the capacity of current radio frequency systems used in space. Known as a technology demonstration, DSOC.....»»
One of 2023"s most extreme heat waves is happening in the middle of winter

Researchers propose new method for pulsar timing and radio-frequency interference mitigation
Radio frequency interference (RFI) caused by human communication techniques (e.g., satellites, base stations, and navigation radars) can significantly distort shapes of multichannel time-frequency radio signals. Subsequent astrophysical measurements,.....»»
New radar research overcomes nearly century-old trade-off between wavelength and distance resolution
New interference radar functions employed by a team of researchers from Chapman University and other institutions improve the distance resolution between objects using radar waves. The results may have important ramifications in military, constructio.....»»
California Waves Have Grown a Foot Taller because of Climate Change
The number of extreme wave events—when crests are taller than 13 feet—have doubled along California since the mid-20th century.....»»
California"s winter waves may be increasing under climate change, nearly a century of data show
A new study from UC San Diego Scripps Institution of Oceanography researcher emeritus Peter Bromirski uses nearly a century of data to show that the average heights of winter waves along the California coast have increased as climate change has heate.....»»
