Synthesis of two new carbides provides perspective on how complex carbon structures could exist on other planets
Researchers at the University of Bayreuth have gained new insights in the field of high-pressure carbon chemistry: They synthesized two new carbides—compounds of carbon and another chemical element—with unique structures. The results may provide.....»»
The Mars Sample Return mission has a shaky future, and NASA is calling on private companies for backup
A critical NASA mission in the search for life beyond Earth, Mars Sample Return, is in trouble. Its budget has ballooned from US$5 billion to over $11 billion, and the sample return date may slip from the end of this decade to 2040......»»
Political "color" affects pollution control spending in the US, new study finds
A new study led by the University of East Anglia (UEA) shows how firms in the United States behave differently depending on the political party in charge—even if they do not change policies......»»

Africa"s megacities threatened by heat, floods, disease—action needed to start greening, adapt to climate change
Cities cover just 3% of the planet. But they emit 78% of all global greenhouse gas emissions, absorb 80% of final global energy (what consumers use) and consume 60% of clean drinking water......»»
Mantle heat may have boosted Earth"s crust 3 billion years ago
Little is known about the nature and evolution of Earth's continental crust before a few billion years ago because cratons, or stable swaths of the lithosphere more than 2–3 billion years old, are relatively rare......»»
Researchers show it"s possible to teach old magnetic cilia new tricks
Magnetic cilia—artificial hairs whose movement is powered by embedded magnetic particles—have been around for a while, and are of interest for applications in soft robotics, transporting objects and mixing liquids. However, existing magnetic cili.....»»
A NASA rover has reached a promising place to search for fossilized life on Mars
While we go about our daily lives on Earth, a nuclear-powered robot the size of a small car is trundling around Mars looking for fossils. Unlike its predecessor Curiosity, NASA's Perseverance rover is explicitly intended to "search for potential evid.....»»
How evolution has optimized the magnetic sensor in birds
Migratory birds are able to navigate and orientate with astonishing accuracy using various mechanisms, including a magnetic compass. A team led by biologists Dr. Corinna Langebrake and Prof. Dr. Miriam Liedvogel from the University of Oldenburg and t.....»»
Australia"s tall, wet forests were not open and park-like when colonists arrived—and we shouldn"t be burning them
Some reports and popular books, such as Bill Gammage's Biggest Estate on Earth, have argued that extensive areas of Australia's forests were kept open through frequent burning by First Nations people. Advocates for widespread thinning and burning of.....»»
Hidden biosphere discovered beneath world"s driest hot desert
In a finding with implications for the search for extraterrestrial life, researchers have discovered microbial life 13 feet below Earth's most inhospitable desert. The research is published in the journal PNAS Nexus......»»

International team detects eruption of mega-magnetic star in nearby galaxy
While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays—high-energy photons—coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explos.....»»
Climate change supercharged a heat dome, intensifying 2021 fire season, study finds
As a massive heat dome lingered over the Pacific Northwest three years ago, swaths of North America simmered—and then burned. Wildfires charred more than 18.5 million acres across the continent, with the most land burned in Canada and California......»»
