Here's why experts don't think cloud seeding played a role in Dubai's downpour

With cloud seeding, it may rain, but it doesn't really pour or flood—at least nothing like what drenched the United Arab Emirates and paralyzed Dubai, meteorologists said.

Resting gray reef sharks change what we know about how they breathe

Predators in perpetual motion. Sleepless in our seas. If that's your image of sharks, you're not alone. And for good reason: sharks must swim to breathe (or so we were told). The science of how sharks sleep and breathe is ...

Physiological and archaeological evidence rewrites assumptions about a gendered division of labor in prehistoric times

Prehistoric men hunted; prehistoric women gathered. At least this is the standard narrative written by and about men to the exclusion of women.

The 'spinaron': New quantum effect challenges the long-held Kondo effect

For the first time, experimental physicists from the Würzburg-Dresden Cluster of Excellence ct.qmat have demonstrated a new quantum effect aptly named the "spinaron." In a meticulously controlled environment and using an ...

Mysterious antimatter observed falling down for first time

For the first time, scientists have observed antimatter particles—the mysterious twins of the visible matter all around us—falling downwards due to the effect of gravity, Europe's physics lab CERN announced on Wednesday.

Antimatter embraces Earth, falling downward like normal matter: Study reveals gravity's effect on matter's elusive twin

For those still holding out hope that antimatter levitates rather than falls in a gravitational field, like normal matter, the results of a new experiment are a dose of cold reality.

Synergy of traditional techniques and deep learning enables single-frame high-precision fringe pattern analysis

Optical metrology, as a general-purpose metrology technique that uses light as information carriers for non-contact and non-destructive measurement, is fundamental to manufacturing, basic research, and engineering applications.
