Stellar rotation drives deep mixing in ageing red giant stars
Advances in supercomputing have enabled astronomers to resolve a long-standing problem in stellar evolution: how changes in the chemical composition at the centers of red giant stars connect to the altered chemistry seen at their surfaces as they age.
Researchers at the University of Victoria's Astronomy Research Centre and the University of Minnesota report that stellar rotation provides India chases 'DeepSeek moment' with homegrown AI models
Fledgling Indian artificial intelligence companies showcased homegrown technologies this week at a major summit in New Delhi, underpinning big dreams of becoming a global AI power.
But analysts said the country was unlikely to have a "DeepSeek moment" - the sort of boom China had last year with a high-performance, low-cost chatbot - any time soon.

TotalEnergies faces cutting back oil and gas production if NGOs prevail in a trial that began Thursday over accusations the French energy giant failed to properly consider environmental risks.
The case, brought by several NGOs and the city of Paris, is based upon a 2017 law that imposed a "duty of vigilance" on large companies.

From adding timestamps to banking transactions to mapping the best route to a destination, satellite navigation plays a significant role in daily life. At the same time, attempts to interfere with and fake navigation signals are increasing. For the last seven months, a new verification service for Galileo has mitigated the threat of spoofing in the Open Service by confirming that the satellite navigation data used for positioning originated in the Galileo system.
