Scientists are developing artificial photosynthesis to make food production more energy-efficient on Earth, and hope the technology could one day be used on Mars. Photosynthesis has evolved in plants over millions of years, converting water, carbon dioxide and energy from sunlight into plant biomass and the food we eat. This process is very inefficient, and

In 2009, Feifei Li , a computer scientist at Princeton University at the time, created a dataset that would change the history of artificial intelligence. The dataset, called ImageNet, contains millions of labeled images that can be used to train sophisticated machine-learning models to recognize what’s in the images. In 2015, these machines surpassed human

In late 2021, operators of the European Space Agency’s (ESA) Swarm constellation of satellites noticed a worrying situation, with satellites measuring the magnetic field around the Earth starting to sink into the atmosphere at an unusually fast rate – 10 times faster than before . The change coincides with the start of a new solar

On June 22, the Zhengzhou Commission for Discipline Inspection issued

In the past, because the CPU and memory were limited, the program needed to be finely polished, and the volume was usually small, and it took up very little CPU and memory resources. But today’s CPUs are powerful enough and have enough memory that not many programmers optimize their programs anymore, and the result is
