Oceanic waves represent fundamental challenges in nonlinear science, say mathematicians
The instability of Stokes waves (steady propagating waves on the surface of an ideal fluid with infinite depth) represents a fundamental challenge in the realm of nonlinear science. A team of researchers recently identified the origin of breaking oce.....»»
Which radio waves disrupt the magnetic sense in migratory birds?
Many songbirds use the Earth's magnetic field as a guide during their migrations, but radio waves interfere with this ability. A new study published has found an upper bound for the frequency that disrupts the magnetic compass......»»
How dangerous is extreme heat to humans?
The media reporting around heat waves that have hammered the northern hemisphere has been unequivocal: the simultaneous record-breaking heat has "pushed the limits of human survival.".....»»
Researchers develop oversampled channelization technology for radio astronomy wideband digital signal
The wideband receiving system of large radio observation equipment obtains a great number of real-time astronomical signals, and the signal preprocessing, transmission, processing and storage have become urgent issues in their operation......»»
Researchers reveal electronic nematicity without charge density waves in titanium-based kagome metal
Electronic nematic order in kagome materials has thus far been entangled with charge density waves. Now it is finally observed as a stand-alone phase in a titanium-based Kagome metal, a team of researchers led by Boston College physicists reported re.....»»
Bushfires focus public attention on climate change for months, but it"s different for storms and floods
As the world warms and the climate changes, people are experiencing more frequent and intense extreme weather events. Just this year, heat waves blasted southern Europe, the United States and China; wildfires lit up Greece, Canada and Maui in Hawaii;.....»»
Coral reefs: How climate change threatens the hidden diversity of marine ecosystems
Like the heat waves on land we have all grown familiar with, marine heat waves are being amplified by climate change. These extreme warm water events have ushered in some of the most catastrophic impacts of climate change and are now a major threat t.....»»
Marine heat wave impact on corals worse than previously thought, according to new research
The effects of marine heat waves caused by climate change on corals and biodiversity are worse than previously thought, according to new University of Victoria research. Published in Science Advances the research also provides important clues about b.....»»
More marine heat waves could spell disaster for ocean life
Marine heat waves are becoming more frequent under global warming and this is having a significant impact on species' ability to recover......»»
New modeling method could drive better understanding of extreme heat waves
To prepare for extreme heat waves around the world—particularly in places known for cool summers—climate-simulation models that include a new computing concept may save tens of thousands of lives......»»
NASA maps key heat wave differences in Southern California
No stranger to hot weather, the Southern California region is facing more humid heat waves that test the adaptability of its residents. But different areas feel different effects......»»
How to prepare your home for summer heat waves
Every year, an estimated 600 people in the U.S. die in extreme heat waves. Nearly 10,000 are hospitalized and more than 67,000 visit emergency rooms. This year, record-smashing heat waves have swept across the southwestern United States, which has sw.....»»
"Coastal squeeze:" Study shows massive loss of US coastline tidal flats over 31 years
Tidal flats, also known as mud flats, make up coastal wetlands that protect against destructive powers from the ocean such as waves, tsunamis and hurricanes. These guardians of the coastlines, however, are under threat due to natural and human events.....»»
Physicists use a 350-year-old theorem to reveal new properties of light waves
Since the 17th century, when Isaac Newton and Christiaan Huygens first debated the nature of light, scientists have been puzzling over whether light is best viewed as a wave or a particle—or perhaps, at the quantum level, even both at once. Now, re.....»»
The World’s Workers Are Donning Cooling Vests to Battle Record Heat Waves
Garments that can be packed with ice or equipped with fans are becoming increasingly popular among workers exposed to high heat......»»
Mars keeps spinning faster every year, NASA InSight data says
Radio signals from the lander help us track Mars' spin as it slowly shifts. Enlarge / A self portrait of InSight's hardware on the red planet. (credit: NASA/JPL-Caltech) To say Mars is a bizarre planet might be something.....»»
Scientists discover shortcut that aids the design of twisty fusion facilities
Scientists have found a mathematical shortcut that could help harness fusion energy, a potential source of clean electricity that could mitigate floods, heat waves, and other rising effects of climate change. The method allows researchers to more eas.....»»
Scientists use FAST to discover a new population of "dwarf" pulses
