India’s leap into solar science: The Aditya-L1 mission

Fresh on the heels of an inaugural Moon landing at the lunar South Pole last month, the Indian Space Research Organisation (ISRO) has done it again with the successful launch of its Aditya-L1 spacecraft. This mission, specifically designed to study the Sun, seeks to answer some of the most pressing questions about our nearest star.Continue reading "India’s leap into solar science: The Aditya-L1...

Table salt could be the secret ingredient for better chemical recycling

Researchers have shown that table salt outperforms other expensive catalysts being explored for the chemical recycling of polyolefin polymers, which account for 60% of plastic waste. The research shows that sodium chloride could provide a safe, inexpensive and reusable way to make plastics more recyclable. The team also showed that table salt and other catalysts could be used in the recycling of...

These worms have rhythm

Researchers have developed a new imaging technique to observe active gene expression in real time. They found that four molecules work together to control the timing of each stage of the C. elegans worm's development. This timekeeping process could provide important clues about the natural rhythm of development in humans and other animals.

Most bees live underground. X-ray images reveal how they build their nests

Despite their reputation as nature’s buzziest pollinators, the vast majority of bee species spend most of their lives underground. Now, thanks to a hospital computed tomography (CT) scanner, researchers have revealed new insights into how these insects build their subterranean lairs. The method could help scientists learn more about how bees contribute to healthy soil and find ways to...

Study provides new insights into British people’s sex lives as they age

Research suggests a sharper decrease in the number of women reporting recent sexual partners after 70 compared with menA study has shed light on how the number of sexual partners British people have changes as they age, and new findings have surprised researchers.While the frequency of sexual partners among heterosexual people declines steadily from age 40, the study found stark gender disparities...

U.K. participation in the world’s largest fusion experiment is in doubt

Most researchers in the United Kingdom are cheering the government’s decision to rejoin the European Union’s €95 billion research program Horizon Europe after a 3-year absence because of Brexit. But for a small group—those working on fusion energy—the news is more mixed. In the same announcement yesterday, the government said it would not seek to rejoin Euratom, a...

How trees influence cloud formation

As part of the international CLOUD project at the nuclear research center CERN, researchers at PSI have identified so-called sesquiterpenes—gaseous hydrocarbons that are released by plants—as being a major factor in cloud formation. This finding could reduce uncertainties in climate models and help make more accurate predictions. The study has now been published in the journal Science...
