Astronomers probe layer-cake structure of brown dwarf"s atmosphere
Brown dwarfs are the cosmic equivalent of tweeners. They're too massive to be planets and too small to sustain nuclear fusion in their cores, which powers stars. Many brown dwarfs are nomadic. They do not orbit stars but drift among them as loners......»»

Research suggests hate speech experiences drop when schools offer structure and adult support
Asian Americans have been the targets of hate speech for generations, particularly during the COVID pandemic. But new research by the University of California, Davis, suggests that Asian American adolescents experience fewer incidents of hate speech.....»»
Researchers successfully fabricate NiS ultrafine nanorods with separated symmetry along two directions
Crystal symmetry is a fundamental concept in materials science, playing a crucial role in determining structure-property relationships. Typically, a crystal is a solid composed of structural units that periodically repeat in three-dimensional space,.....»»
How to watch Europe launch a new Earth observation satellite tonight

Asian forests show resilience despite rising disturbances from climate change and human activities
Since 1850, global temperatures have been steadily rising. Human activities have significantly increased the emissions of greenhouse gases into the atmosphere, exacerbating the greenhouse effect and global warming. Forests in Asia have faced numerous.....»»
Tropical forest resilience to seasonal drought linked to nutrient availability
Tropical forests are highly productive ecosystems, accounting for nearly half of the global forest carbon sink. If tropical forests can no longer remove carbon dioxide from the atmosphere, the effects of climate change may become even more severe......»»
Video: Unraveling the mysteries of clouds
Clouds are one of the biggest mysteries in the climate system. They play a key role in regulating the temperature of our atmosphere. But we don't know how their behavior will change over time as Earth's atmosphere gets warmer. This is where EarthCARE.....»»
Camera tags capture social flexibility of Antarctic minke whales
Researchers have conducted one of the first quantitative studies of social structure and social foraging in Antarctic minke whales, using pioneering animal-borne camera tags......»»
Black holes are firing beams of particles, changing targets over time
Black holes seem to provide endless fascination to astronomers. This is at least partly due to the extreme physics that takes place in and around them, but sometimes, it might harken back to cultural touchpoints that made them interested in astronomy.....»»

Will clouds help cool or warm our world in the years ahead? The EarthCARE satellite will soon blast off on a mission to find out, aiming to investigate what role clouds could play in the fight against climate change......»»
TESS finds intriguing world sized between Earth and Venus
Using observations by NASA's TESS (Transiting Exoplanet Survey Satellite) and many other facilities, two international teams of astronomers have discovered a planet between the sizes of Earth and Venus only 40 light-years away. Multiple factors make.....»»
Dyson spheres: Astronomers report potential candidates for alien structures, and evidence against their existence
There are three ways to look for evidence of alien technological civilizations. One is to look out for deliberate attempts by them to communicate their existence, for example, through radio broadcasts. Another is to look for evidence of them visiting.....»»

Saltmarshes do store carbon, but their climate impact may have been overestimated
Saltmarshes, or tidal marshes, are able to capture carbon dioxide from the atmosphere and lock it away at a far higher rate than even forests on land. This has lead to them being championed as a nature-based solution to climate change. However, our r.....»»
