Unraveling the stellar content of young clusters

About twenty-five percent of young stars in our galaxy form in clustered environments, and stars in a cluster are often close enough to each other to affect the way they accrete gas and grow. Astronomers trying to understand ...

Lensless light-field imaging through diffuser encoding

Microlens array based light-field imaging generally suffers from an intrinsic trade-off between the spatial and angular resolutions. To this end, scientists in China and German jointly proposed a lensless light-field imaging ...

New method to magnify digital images is 700 times faster

Aránzazu Jurío-Munárriz, a graduate in computer engineering from the NUP/UPNA-Public University of Navarre, has in her PhD thesis presented new methods for improving two of the most widespread means used in digital image ...

Satellites detect methane plume in Nord Stream leak

Following unusual seismic disturbances in the Baltic Sea, several leaks were discovered last week in the underwater Nord Stream 1 and 2 gas pipelines, near Denmark and Sweden. Neither pipeline was transporting gas at the ...

In 2020, 30% of the Pantanal was burned to cinders by wildfires

In 2020, the Pantanal, the largest tropical freshwater wetland in the world and a biodiversity hotspot, was swept by high-intensity fires that destroyed native vegetation in an area totaling 44,998 square kilometers, or about ...

Nondestructive 3-D imaging of biological cells with sound

Much like magnetic resonance imaging (MRI) is able to scan the interior of the human body, the emerging technique of "picosecond ultrasonics," a type of acoustic imaging, can be used to make virtual slices of biological tissues ...
