Turbulence flux observations at tower-based platform reveal modulation mechanism of wind waves on surface wind
Recently, a study by Associate Prof. Sheng Chen and Prof. Fangli Qiao from the First Institute of Oceanography, Ministry of Natural Resources was published in Science China Earth Sciences. The observational data from a coastal tower-based platform ar.....»»
Bee populations at risk of one-two punch from heat waves, pathogen infection
The historically high heat waves that gripped the southwest United States and southern Europe this summer are causing problems for more than just humans. Extreme heat waves affect pollinators and the pathogens that live on them, creating a mutual imb.....»»
July was the planet"s hottest month on record—so far
A sizzling month marked by record heat waves, major wildfires, melting sea ice and a burgeoning El Niño will go down in the books as the hottest July on record—at least until next year, federal officials said Monday......»»
As we head toward summer, researchers suggest a rethink of Australia"s bushfire risk
Winter is the off-season when it comes to bushfires in southern Australia. But people could be forgiven for feeling anxious ahead of the Australian summer, with the Northern Hemisphere experiencing scorching heat waves, tourists fleeing fires in Gree.....»»
Riding a wave to better medical diagnostic imaging
Medical imaging via X-rays, CT scans, MRIs and ultrasounds provide health-care professionals with unique perspectives and a better understanding of what's happening inside a patient's body. Using various forms of waves, these machines can visualize m.....»»
Death tolls from climate disasters will "balloon" without investment in Africa"s weather stations, experts warn
The climate crisis is increasing the frequency and intensity of floods, droughts and heat waves, with Africa expected to be among the global regions hit hardest......»»
Wild ‘heartbreak’ star has waves three times the height of the sun
An enormous new type of star that researchers are calling a heartbreak star has waves on its surface that are three time the size of our sun......»»
Antarctica risks "cascades of extreme events" as Earth warms, study says
Extreme weather in Antarctica, including ocean heat waves and ice loss, is set to become more intense unless urgent policy action reduces the burning of fossil fuels, a new study has found—the latest to sound the alarm on the damage climate change.....»»
Saturday Citations: Muons and the standard model, refuting an apocalypse, stellar tidal waves
This week on phys.org, we published news about muons, gigantic stellar waves, a Homo-erectus-thwarting mini ice age, and a new whale guy......»»
Satellites document effects of heat waves on plants
A new scientific study shows how periods of drought affect photosynthesis throughout the course of the day. The study found that plants in regions that are typically dry increase their CO2 intake during the morning hours during a heat wave and decrea.....»»
How language can turn down the temperature of heated climate change discourse
The world is burning. Death Valley, Calif., shattered the record in July 2023 for the hottest temperature on earth. Meanwhile, July 2023 is now the hottest month in recorded history and scientists have noted heat waves are 1,000 times more likely wit.....»»
Climate projections detail future risks for many people worldwide
Extreme weather events have dominated the news this summer, with reports on extensive wildfires in Canada; dangerous flooding in India, Japan, and the Eastern U.S.; severe heat waves in Spain, China, the United States, and Mexico; and the hottest day.....»»
Stellar surf"s up: Monster waves as tall as three suns are crashing upon a colossal star
An extreme star system is giving new meaning to the phrase "surf's up.".....»»
Study finds rain-driven microbial pollution persists at surfing beaches in colder months
Surfers at beaches where stormwater drainage pipes discharge into the ocean risk catching more than waves on a rainy day. Monmouth University researchers studying the influence of weather and ocean conditions on microbial pollution found that within.....»»
After 15 years, pulsar timing yields evidence of cosmic background gravitational waves
The universe is humming with gravitational radiation—a very low-frequency rumble that rhythmically stretches and compresses spacetime and the matter embedded in it......»»
New technique measures structured light in a single shot
Structured light waves with spiral phase fronts carry orbital angular momentum (OAM), attributed to the rotational motion of photons. Recently, scientists have been using light waves with OAM, and these special "helical" light beams have become very.....»»
Gravitational waves may reveal nature of dark matter
Observations of gravitational waves from merging black holes may reveal new insights about dark matter, suggests a new study from a UCL-led international team......»»
Physicists open new path to an exotic form of superconductivity
Physicists have identified a mechanism for the formation of oscillating superconductivity known as pair-density waves. Physical Review Letters published the discovery, which provides new insight into an unconventional, high-temperature superconductiv.....»»
New Antarctic extremes "virtually certain" as world warms
Extreme events in Antarctica such as ocean heat waves and ice loss will almost certainly become more common and more severe, researchers say......»»
