Unprecedented heat wave on the Tibetan plateau: Study highlights land-atmosphere interactions
Heat waves are generally thought to occur in hot, lowland regions—but what happens when extreme heat strikes the frigid, high-altitude Tibetan Plateau? Is the definition of a heat wave the same at 5,000 meters above sea level as it is in the plains.....»»
New dense sub-Saturn exoplanet discovered
Using the Transiting Exoplanet Survey Satellite (TESS), astronomers from the Physical Research Laboratory (PRL) in Ahmedabad, India and elsewhere, have detected a new sub-Saturn exoplanet with a relatively high density. The finding was reported in a.....»»
Scientists prove long-standing wave amplification theory
Physicists at the University of Southampton have tested and proven a 50-year-old theory for the first time using electro-magnetic waves. They have shown that the energy of waves can be increased by bouncing "twisted waves"—those with angular moment.....»»
Surf therapy connects people to water—ocean health depends on this "blue attunement"
As a lifelong surfer, born to pioneering surfing parents and named after a wave, the ocean has shaped my identity and sense of belonging. The movement and touch of ocean waves ignites a whole cascade of changes in emotions in me and affects how I sen.....»»

Plasmonic modulators could enable high-capacity space communication
Researchers have achieved data rates as high as 424Gbit/s across a 53-km turbulent free-space optical link using plasmonic modulators—devices that use special light waves called surface plasmon polaritons to control and change optical signals. The.....»»
Gravitational waves unveil previously unseen properties of neutron stars
A better understanding of the inner workings of neutron stars will lead to a greater knowledge of the dynamics that underpin the workings of the universe and also could help drive future technology, said the University of Illinois Urbana-Champaign ph.....»»
Eclipses create atmospheric gravity waves, student teams confirm
Student teams from three U.S. universities became the first to measure what scientists have long predicted: eclipses can generate ripples in Earth's atmosphere called atmospheric gravity waves. The waves' telltale signature emerged in data captured d.....»»

Scientists demonstrate giant THz Kerr effect via stimulated phonon polaritons
Terahertz (THz) waves and THz technologies have gradually opened a new style for communications, cloud-based storage/computing, information contest, and medical tools. With the advancement of THz technologies, studies on THz nonlinear optics have eme.....»»
Seismic echoes reveal a mysterious "donut" inside Earth"s core
About 2,890 kilometers beneath our feet lies a gigantic ball of liquid metal: our planet's core. Scientists like me use the seismic waves created by earthquakes as a kind of ultrasound to "see" the shape and structure of the core......»»
Data from space probes show that Alfvén waves drive the acceleration and heating of the solar wind
By studying data from NASA's Parker Solar Probe and the ESA Solar Orbiter, an international team of astrophysicists has found that Alfvén waves drive the acceleration and heating of the solar wind......»»
EU investigating if Telegram played down user numbers to avoid regulation

Air conditioning poses a climate conundrum
This week, much of the US is suffering from yet another heat wave. So far this year, 15 countries have set records for high heat. Last July, the average global temperature, factoring in heat waves in multiple regions around the world, was likely the.....»»
Arctic heat waves linked to sea ice loss, new study reveals
Amid global warming, heat waves are striking even the Arctic, a region once considered immune to such extreme weather events. Recent research reveals that these heat waves, particularly in the Barents-Kara Sea (BKS) during the boreal autumn, are not.....»»
