C'est vrai que les solstices et équinoxes tombent forcément le 21 du mois ?On sait qu'ils ont lieu aux alentours de cette date, alors pour aller plus vite on parle toujours du 21 comme référence. Mais est-ce ces évènements saisonniers sont vraiment toujours placés ce jour-là dans notre...
It's not so much where people live, but where they frequently spend their time, that can provide useful information for predicting community health measures. A team led by geographers in the Penn State College of Earth and Mineral Sciences found that adding place visitation data—geographic data points collected from millions of anonymous cellphone users with GPS-enabled devices—to a population health model increased the model's predictive performance by an average of 7.5%.
Rainwater connects the biogeochemical cycles of land and the atmosphere. It's effectively a chemical conveyor belt that delivers compounds to the ground during a process called wet deposition.
Election officials can build public trust in procedures and results—even among suspicious voters who fear partisan manipulation—by creating videos that factually explain their security safeguards in simple terms. These are the findings of studies co-authored by a UC Riverside scholar, offering strategies for election officials to respond to false claims and conspiracy theories about election fraud and security, as well as suspicions that arise when mail-in ballot counting delays results.
Seasonal changes redistribute enough water around Earth to shift the planet's center of mass back and forth by fractions of an inch relative to its geometric center. NASA scientists are on the case, tracking the oscillations because Earth's center of mass is a crucial reference point for satellite navigation and elevation measurements.
Astronomers have confirmed a world less than a million years old as the youngest known planet, using data from archives. Called Elias 2-24 b, the baby planet is still whirling in its natal disk of dust and gas.
Arctic sea ice moves and spreads in ways that wind alone cannot explain. A new UC Riverside-led study finds that collisions between individual pieces of ice provide a surprisingly simple explanation for these movements, potentially offering scientists a better way to predict where sea ice will travel as the Arctic warms.
Right now, your brain is recognizing the shapes of these letters, analyzing their meaning and holding a stream of thought together—all on about 20 watts of power. That's roughly what it takes to run a light bulb.
MIT researchers have created a computing platform that could be used to develop intelligent and adaptive next-generation electronics that can perform multiple functions, like computing and memory, within one extremely compact, energy-efficient device.
Researchers at Maynooth University (MU) have developed a first-of-its-kind DNA computer, described as one of the most complex and fastest molecular computers yet reported.
At just an inch (2.5 centimeters) long, the sand hoppers skipping across California's Isla Vista Beach at dawn don't exactly look like a force of nature. But a new study reveals that these shrimp-like creatures might be doing more to shape the landscape in which they live than any other animal on Earth.

A 178-year-old mystery surrounding one of the earliest recorded examples of space weather affecting technology has been solved by an international team led by Lancaster University.

Across its basins and thousands of meters down, the Mediterranean Sea is getting warmer and saltier. Now, a new study finds it is also doing so at an increasingly rapid pace. The speedup is largest in the central and eastern Mediterranean and strongest of all in the Adriatic, where it reaches all the way to the sea floor.
