Ammonia (NH3) is a major component in fertilizer and a promising carbon-free energy carrier. However, ammonia production consumes around 2 percent of the world's total energy production and releases 500 Mt of carbon dioxide annually. A research team led by scientists at City University of Hong Kong (CityU) developed a new kind of photocatalyst that can produce ammonia from atmospheric nitrogen at room temperature using sunlight. This new method outperformed the conventional way which causes massive carbon emissions. The research team believed that such technology of sustainable ammonia production would advance the development of the future nitrogen economy. This research...

Video transcript   Energy developments Primary energy consumption fell by 4.5% in 2020 – the largest decline since 1945. The drop in energy consumption was driven mainly by oil, which contributed almost three-quarters of the net decline, although natural gas and coal also saw significant declines. Wind, solar and hydroelectricity all grew despite the fall in overall energy demand. By country, the US, India and Russia contributed the largest declines in energy consumption. China posted the largest increase (2.1%), one of only a handful of countries where energy demand grew last year. Carbon emissions Carbon emissions from energy use fell by 6.3%, to their lowest level...

Microsoft and Nvidia surpass OpenAI by creating "the world’s largest and most powerful generative language model,”Megatron-Turing Natural Language Generation model (MT-NLG). Just under a year and a half ago OpenAI announced completion of GPT-3, its natural language processing algorithm that was, at the time, the largest and most complex model of its type. This week, Microsoft and Nvidia introduced a new model they’re calling “the world’s largest and most powerful generative language model.” The Megatron-Turing Natural Language Generation model (MT-NLG) is more than triple the size of GPT-3 at 530 billion parameters. GPT-3’s 175 billion parameters was already a lot; its predecessor, GPT-2, had...

Episode 1 of the Rethinking Humanity series by @RethinkX explores how humanity is failing to see its immediate future: a decade of existential transformation, triggered by technologies converging deep in the foundations of our global civilization. We all feel the tremors, but we’re blind to the deeper process of change. Before it’s too late, we must all see the mind-blowing possibility space of the next decade, as well...
