Scientists discover a long-sought global electric field on Earth
Using observations from a NASA suborbital rocket, an international team of scientists, for the first time, has successfully measured a planet-wide electric field thought to be as fundamental to Earth as its gravity and magnetic fields......»»
Environmental policy in Brazil leads to less violence, researchers find
In December 2007, the then Brazilian government passed a law to curb the illegal destruction of the rainforest. A study by researchers from the Insper Research Institute in São Paulo and the University of Bonn now shows an interesting side effect: w.....»»
Climate change feedbacks lead to surge in natural methane emissions
Attempts to cut greenhouse gases made tougher by increased emissions. Enlarge / A view of the Pantanal wetlands in Brazil. New research shows a large chunk of global methane emissions are from rotting vegetation in tropical wetla.....»»
How a survey of over 2,000 women in the 1920s changed the way Americans thought about female sexuality
American women still have fewer orgasms than men, according to new research that suggests that decades after the sexual revolution, the "orgasm gap" is still very much in effect......»»
Sol-gel transition effect based on thermosensitive hydrogel shows promised for photo-assisted uranium extraction
To achieve carbon reduction goals, reducing emissions is crucial, and nuclear power plays a key role in providing reliable, low-carbon electricity, aiding carbon neutrality. However, the nuclear industry faces the significant challenge of managing ur.....»»

In six new rogue worlds, Webb Telescope finds more star birth clues
The James Webb Space Telescope has spotted six likely rogue worlds—objects with planetlike masses but untethered from any star's gravity—including the lightest ever identified with a dusty disk around it......»»
Fires in Brazil"s Sao Paulo state under control: authorities
Fires that have razed thousands of hectares of forest in Brazil's Sao Paulo state have been brought under control, authorities said Monday, though an alert for fresh blazes remained in place......»»
Brazil waging "war" on wildfires in crowded Sao Paulo state
Brazil was deploying military aircraft as part of a "war" against wildfires ravaging the southeastern state of Sao Paulo, with authorities warning on Sunday that arsonists were setting blazes......»»
The Quantum Mechanics of the Greenhouse Effect
Carbon dioxide’s powerful heat-trapping effect has been traced to a quirk of its quantum structure. The finding may explain climate change better than any computer model......»»
Bonobo evidence suggests ancient origin of the "common enemy effect"
In the face of threats from other groups, humans, chimpanzees, and a selection of other species get closer to their own. Now an international team led by Kyoto University has shown that even our more peaceful cousins, bonobos—who have never been ob.....»»
Nitrogen deposition also reduces biodiversity on a larger scale, research shows
It has long been known that nitrogen deposition, where nitrogen is released from the atmosphere into soil or water, can lead to biodiversity loss on a small scale. New research shows that this effect can also be seen in larger areas of several kilome.....»»
