Powerful hurricanes strengthen faster now than 30 years ago

Hurricanes that intensify rapidly—a characteristic of almost all powerful hurricanes—do so more strongly and quickly now than they did 30 years ago, according to a study published recently in Geophysical Research Letters, ...

The taming of the light screw

DESY and MPSD scientists have created high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might ...

Climate models disagree on why temperature 'wiggles' occur

A new Duke University-led study finds that most climate models likely underestimate the degree of decade-to-decade variability occurring in mean surface temperatures as Earth's atmosphere warms. The models also provide inconsistent ...

Entanglement in a flash (w/ video)

(Phys.org) —JQI researchers under the direction of Chris Monroe have produced quantum entanglement between a single atom's motion and its spin state thousands of times faster than previously reported, demonstrating unprecedented ...

A common mechanism for human and bird sound production

When birds and humans sing it sounds completely different, but now new research reported in the journal Nature Communications shows that the very same physical mechanisms are at play when a bird sings and a human speaks.

La Nina caused global sea level drop

The 2011 La Niña was so strong that it caused global mean sea level to drop by 5 millimeters (0.2 inches), a new study shows. Since the early 1990s, sea level has been rising by about 3 millimeters (0.1 inches) per year, ...

Researchers make droplets dance (w/ Video)

(Phys.org) —Researchers from Aalto University and Paris Tech have placed water droplets containing magnetic nanoparticles on strong water repellent surfaces and have made them align in various static and dynamic structures ...
