University of California, Irvine biomedical engineering researchers have uncovered a previously unknown source of two key brain waves crucial for deep sleep: 

Let’s look back at the week in Opinion.

(UCI) researchers have been conducting much of that study, learning what exactly will be needed to make all cars zero emissions over the next decade.

Cornell researchers have developed nanostructures that enable record-breaking conversion of laser pulses into high-harmonic generation, paving the way for new scientific tools for high-resolution imaging and studying physical processes that occur at the scale of an attosecond – one quintillionth of a second. ... The research is detailed in the paper “Generation of Even and Odd High Harmonics in Resonant Metasurfaces Using Single and Multiple Ultra-Intense Laser Pulses,” published on July 7, 2021, in Nature Communications.

"The interhemispheric teleconnection that we have discovered promises earlier and more accurate prediction of winter precipitation in California and the southwestern U.S.," Efi Foufoula-Georgiou, University of California, Irvine Distinguished Professor of civil and environmental engineering and co-author of the study, said in a release.

Neuroscientists have discovered a surprising new source of deep-sleep brain waves, shaking up our understanding of the architecture of sleep and how we treat sleep disorders. … "These findings have significant implications for sleep research, potentially paving the way for new approaches to treating sleep-related disorders," co-author Gregory Brewer, adjunct professor of biomedical engineering at UC Irvine, said in a statement.
