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......»»
A new test proves how to make the Event Horizon Telescope even better
Want a clear view of a supermassive black hole's environment? It's an incredible observational challenge. The extreme gravity bends light as it passes through and blurs the details of the event horizon, the region closest to the black hole. Astronome.....»»
Engineers smash rocks to see what occurs when top layer of an asteroid-like object is hit with extreme external force
Johns Hopkins engineers have uncovered new details about how granular materials such as sand and rock behave under extreme impacts—findings that could someday help protect the Earth from dangerous asteroids......»»
Global South cities lack cooling green spaces
Cities in the Global South are more exposed to extreme heat because they lack cooling green spaces, new research shows. The study found that Global South cities have just 70% of the "cooling capacity" provided by urban greenery in the Global North. T.....»»
"More than just numbers:" Statistics expert uses data to predict extreme weather, financial downturns
Using data and numbers, a West Virginia University statistician is exploring new methods that could predict and model extreme patterns in weather events, financial turmoil and pollution levels......»»
New model to enhance extreme rainfall prediction
New research by an international team of climate experts shows intense, localized, heavy bursts of rainfall can be caused by a rapid rise of air through clouds and proves that these rises in air can be forecast. The team has developed a unique, cutti.....»»
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.....»»
NASA study tallies carbon emissions from massive Canadian fires
Stoked by Canada's warmest and driest conditions in decades, extreme forest fires in 2023 released about 640 million metric tons of carbon, NASA scientists have found. That's comparable in magnitude to the annual fossil fuel emissions of a large indu.....»»
Extreme weather threatens survival of seabirds and seals
Scientists have identified the Australian and Antarctic marine predators most vulnerable to the impacts of climate change, and it will help focus conservation efforts for species under threat......»»
Biomass-based polymer can capture and release CO₂ without high pressure or extreme temperatures
A new, biomass-based material developed by FAMU-FSU College of Engineering researchers can be used to repeatedly capture and release carbon dioxide......»»
Record-breaking drought in southern China linked to Eurasian warming and tropical sea surface temperature
Southern China experienced an extreme drought that persisted from summer to autumn in 2022, ranking as the most severe drought since 1980. The reason for the occurrence of this extreme drought event was investigated. It shows that both the Eurasian w.....»»

Extreme rainfall event study demonstrates improved forecasting via physics-guided machine learning
A research team focused on the extreme rainfall event of "21·7" in Henan in 2021. By analyzing anomalous physical characteristics and understanding multi-model forecast biases, they significantly enhanced the accuracy of precipitation intensity fore.....»»
Study tracks decades of extreme heat, cold in Upper Midwest
Researchers analyzed meteorological data from nine Upper Midwest states from 1979–2021, tracking trends in extreme heat and cold over every 4-kilometer square of that territory. They found striking regional differences in the extremes. Many parts o.....»»
What the unique shape of the human heart tells us about our evolution
Mammals, from the mighty blue whale to the tiny shrew, inhabit nearly every corner of our planet. Their remarkable adaptability to different environments has long fascinated scientists, with each species developing unique traits to survive and thrive.....»»
The overshoot myth: We can"t keep burning fossil fuels and expect scientists of the future to get us back to 1.5°C
Record breaking fossil fuel production, all-time high greenhouse gas emissions and extreme temperatures. Like the proverbial frog in the heating pan of water, we refuse to respond to the climate and ecological crisis with any sense of urgency. Under.....»»
Ancient civilizations had ways to counter the urban heat island effect—how history"s lessons apply to cities today
As intense heat breaks records around the world, a little-reported fact offers some hope for cooling down cities: Under even the most intense periods of extreme heat, some city blocks never experience heat wave temperatures......»»
"Amazon" algae shed light on what happens to populations when females switch to asexual reproduction
Researchers at Max Planck Institute for Biology Tübingen and Kobe University discovered populations of female brown algae that reproduce from unfertilized gametes and thrive without males. In a study published in Nature Ecology & Evolution, they use.....»»
Hailstone library to improve extreme weather forecasting
