The same dirt that clings to astronauts' boots may one day keep their lights on. In a study published in Device, researchers created solar cells made out of simulated moon dust. The cells convert sunlight into energy efficiently, ...
When Hunga Tonga–Hunga Haʻapai, an underwater volcano near Tonga in the South Pacific Ocean, erupted in 2022, scientists expected that it would spew enough water vapor into the stratosphere to push global temperatures ...
An international team led by UNIGE shows that red and dead galaxies can be found only 700 million years after the Big Bang, indicating that galaxies stop forming stars earlier than predicted by models.
Screen-printed, biodegradable soil sensors that can be composted at the end of their lifecycle could enable farmers to improve crop yields while reducing electronic waste, researchers say.
Every year, from December to April, the Harmattan sweeps across Africa. This cool, dry and dust-laden wind gets its name from haramata, a word in the Ghanaian language Fanti.
In the quest for next-generation energy, sensing, and pigment technologies, semiconducting metal oxides like titanium dioxide (TiO₂) have emerged as essential materials due to their abundance, stability, and intriguing ...
Inside a green orb planted in the German countryside is a high-tech aid to prevent wildfires that have grown more common and destructive with rising global temperatures.
Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and consist of an array of tiny ...
A team of researchers from UNIST has developed a new technology that uses solar energy to produce ammonia and glycolic acid—an essential component in cosmetics—while eliminating carbon dioxide emissions.
Researchers from the Yunnan Observatories of the Chinese Academy of Sciences and Southwest Forestry University have developed an advanced neural network-based method to improve the compression of spectral data from the New ...
