Strobe light for 5G: Imaging system spotlights the tiny mechanical hearts at the core of every cellphone: Movies of minuscule vibrations reveal how well 5G and other mobile networks are operating
Inside every cellphone lies a tiny mechanical heart, beating several billion times a second. These micromechanical resonators play an essential role in cellphone communication. Buffeted by the cacophony of radio frequencies in the airwaves, these resonators select just the right frequencies for transmitting and receiving signals between mobile devices. With the growing importance of these […]

Comets’ heads can be green, but never their tails. After 90 years, we finally know why: The team solved this mystery with the help of a vacuum chamber, a lot of lasers, and one powerful cosmic reaction.
Every so often, the Kuiper Belt and Oort Cloud throw galactic snowballs made up of ice, dust and rocks our way: 4.6-billion-year-old leftovers from the formation of the solar system. These snowballs — or as we know them, comets — go through a colourful metamorphosis as they cross the sky, with many comets’ heads turning […]
Concurrent heatwaves seven times more frequent than in 1980s
Multiple large heatwaves the size of Mongolia occurred at the same time nearly every day during the warm seasons of the 2010s across the Northern Hemisphere, according to a study led by Washington State University researchers. Using climate data from 1979 to 2019, the researchers found that the number of heatwaves occurring simultaneously in the […]

Eating walnuts daily lowered ‘bad’ cholesterol and may reduce cardiovascular disease risk
Eating about ½ cup of walnuts every day for two years modestly lowered levels of low-density lipoprotein (LDL) cholesterol, known as “bad cholesterol,” and reduced the number of total LDL particles and small LDL particles in healthy, older adults, according to new research published today in the American Heart Association’s flagship journal Circulation. Healthy older […]
