Compound extreme events stress the oceans
It's not just the land that is groaning under the heat—the ocean is also suffering from heatwaves. In the Mediterranean Sea along the Italian and Spanish coasts, for example, water temperatures are currently up to 5 °C higher than the long-term av.....»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
Enhancing hurricane forecasts: Simulations reveal reducing estimates of atmospheric friction improves storm predictions
Hurricanes and other extreme weather events are expensive in lives and money. From 1980 to 2023, weather and climate disasters caused about $2.6 trillion in damages in the U.S., according to NOAA estimates. In 2022 alone, the U.S. experienced 18 disa.....»»
Extreme heat impacts daily routines and travel patterns, study finds
A new study conducted by a team of researchers from Arizona State University, University of Washington and the University of Texas at Austin reveals that extreme heat significantly alters how people go about their daily lives, influencing everything.....»»
Future climate change predicted to shift flood-generating mechanisms and intensify extreme flooding events
The Delaware River Basin, a coastal watershed in the Mid-Atlantic region, has a long history of severe flooding with significant socioeconomic impacts. Recent research uses a process-based modeling approach to analyze hydrometeorological (like rainfa.....»»
Satellite data fusion enhances the early detection of convective clouds
As global warming continues, convective weather events are becoming more frequent. The early stage of these storms, known as convective initiation (CI), can be monitored using geostationary satellites. However, detecting CI accurately remains a chall.....»»
Scientists uncover a critical component that helps killifish regenerate their fins
Spontaneous injuries like the loss of a limb or damage to the spinal cord are impossible for humans to repair. Yet, some animals have an extraordinary capacity to regenerate after injury, a response that requires a precise sequence of cellular events.....»»
Hurricanes, storms, typhoons... Is September wetter than usual?
With typhoon Yagi battering Asia, storm Boris drenching parts of Europe, extreme flooding in the Sahel and hurricane Helene racing towards Florida, September so far has been a very wet month......»»
Hummingbirds thrive on an extreme lifestyle. Here’s how.
Nightly suspended animation, sugary diet, backwards flight, and long migrations help. Enlarge / Hummingbirds—like this golden-tailed sapphire from South America—draw the eye with their bright colors and busy, hovering flight......»»
"Tamed" molecules for more sustainable catalysts: Chemists succeed in synthesizing a spectacular gallium compound
Catalysts play an important role in the manufacture of many products that we encounter in everyday life—for example in cars for exhaust gas purification or in the chemical industry in the production of fertilizers. Catalysts ensure that these react.....»»
NOAA shares first data from GOES-19 EXIS instrument
The Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS) onboard NOAA's GOES-19 satellite, which launched on June 25, 2024, are powered on, performing well, and observing the sun......»»
Study finds extreme temperatures increase mortality rates, with heat disproportionately affecting minorities
A new study examined how extreme temperatures in the United States significantly affect mortality among different racial groups and found that both cold and hot days increase mortality rates, with the latter disproportionately affecting underrepresen.....»»
Climatologists develop more accurate El Niño Southern Oscillation forecasts
Australian climatologists closely monitor atmospheric and oceanic conditions to assess the risk of El Niño Southern Oscillation (ENSO) events occurring, which can lead to devastating natural disasters, however these predictions have become somewhat.....»»
Extreme botany: Paramotorists soar across remote Peru desert to collect threatened plants
In an innovative paper published today in the journal Plants, People, Planet, scientists from the Royal Botanic Gardens, Kew, Huarango Nature and paramotorists from Forest Air, highlight the exciting potential of paramotoring as a means of aiding res.....»»
Evaluating the flow of information for high-impact weather events
Sixteen years to the day that Hurricane Katrina devastated Louisiana, Ida slammed into the Gulf Coast state's seaport town of Port Fourchon as a Category 4 cyclone on Aug. 29, 2021, leaving a widespread path of destruction......»»
Study finds good nutrition boosts honey bee resilience against pesticides, viruses
In a new study, researchers at the University of Illinois Urbana-Champaign tackled a thorny problem: How do nutritional stress, viral infections and exposure to pesticides together influence honey bee survival? By looking at all three stressors toget.....»»
Feeding coral reefs can aid their recovery from bleaching events
Coral reefs will continue to experience severe heat stress as rising temperatures cause the oceans to become unbearably hot—but a new study shows that altering their feeding habits could allow local populations to avoid total extinction......»»
Arlo Secure gets powerful new AI features, including person and vehicle detection
Arlo Secure can now send you personalized alerts when people or vehicles enter your property. You can even create custom alerts for specific motion events......»»
Evaluating changes in dissolved inorganic carbon in the Greenland Sea
To know whether we are complying with emission treaties, all CO2 must be traceable. Incomplete bookkeeping recently sent scientists on a search in the Greenland Sea. Their research is published in the Journal of Geophysical Research: Oceans......»»
Study raises questions about validity of standard model of solar flares
Solar flares are extremely intense events that occur in the sun's atmosphere, lasting anywhere from a few minutes to several hours. According to the standard flare model, the energy that triggers these explosions is transported by accelerated electro.....»»
Extreme polar light environment of the North and South Poles sustains biodiversity, researchers suggest
Researchers working in Finland propose that the unique light environment of the Earth's polar regions creates conditions that result in circumpolar hybrid zones around the North and the South Poles. These extreme conditions increase the synchrony of.....»»
