An experimental lung disease drug developed using artificial intelligence showed promise in reversing biological signs of aging, pointing to broader potential use of the treatment, according to its developer. In a midstage study, Insilico Medicine's drug rentosertib helped reduce biological age as measured by six different aging clocks examining chemical changes in the body, according to an analysis published in Nature Biotechnology on Monday. Those who were given a placebo saw little change in their biological age on those same clocks, the Hong Kong-listed company said. "If your biological age is lower, you are likely to die later," the AI drug discovery startup's CEO, Alex Zhavoronkov, said in an interview. He cautioned that the results are still early and the long-term health effects of the drug on larger groups of people are unknown.

South Korea's power demand set to soar on AI boom South Korean Minister of Climate, Energy and Environment Kim Sung-whan checks data of the Han River Flood Control Office's flood forecasting system in Seoul on Sept. 2. | REUTERS SEOUL - South Korea's demand for power in the coming years is set to surge on plans by chipmakers Samsung Electronics and SK Hynix to expand production and the building of new artificial intelligence data centers, according to the country's energy minister. Those AI-driven power needs alone will lift South Korea's demand for power by 25 to 30 gigawatts, the Minister of Climate, Energy and Environment Kim Sung-whan said in an interview this month. On top of that, the country will also need to contend with increased power demand due to the shift to electric vehicles from gasoline-engine cars and to heating via electricity rather than gas, he added.

What is Iran's Pickaxe Mountain? Crude oil and natural gas supplies have been disrupted worldwide by the United States-Israel war on Iran, but one energy sector appears to be cashing in - coal. This week, South Africa's thermal coal producer Thungela Resources said it had doubled its half-year profits as the war has forced more countries to buy the fuel. Mining it causes water pollution, and burning it releases enormous amounts of carbon into the atmosphere, which contributes to global warming. In recent months, several countries, especially in Asia, have reversed or delayed promises to scale back on coal production.

South Korean chip giant SK Hynix has raised a record-breaking $26.5bn ahead of its Wall Street debut amid soaring demand for semiconductors used in AI. SK Hynix said on Friday that it had sold 177.9 million American depositary shares (ADS) at $149 each ahead of its listing on the New York-based Nasdaq stock exchange. SK Hynix's 177.9 million ADSs are equivalent to 18 million ordinary shares. SK Hynix's initial public offering (IPO) marks the largest-ever listing by a foreign company in the US, surpassing Chinese e-commerce giant Alibaba's $25bn debut in 2014. The listing also ranks as the second-largest globally, after SpaceX's record-breaking $85.7bn Nasdaq listing in June.

South Korean computer chip maker SK Hynix has raised $26.5bn (£19.8bn) in its New York share offering, marking the largest ever listing by a foreign firm in the US. The company, a key supplier to artificial intelligence (AI) chip giant Nvidia, said on Thursday that it had sold 177.9 million American depositary shares for $149 each. The shares are set to begin trading on Friday on the Nasdaq. In May, SK Hynix saw its market value top $1tn in its home country, lifted by the boom in demand for AI chips. Its share price has more than tripled in South Korea this year, which along with Samsung Electronics has helped boost the benchmark Kospi index by more than 70% over the same period.

Image caption, Samsung is also one of the world's leading smartphone makers South Korean technology giant Samsung Electronics says it expects to post a 19-fold jump in its profits, driven by global demand for artificial intelligence (AI) memory chips. The company forecast that it made 89tn won (£44bn; $58bn) between the start of April and the end of June, marking its third record quarterly operating profits in a row. Major South Korean firms like Samsung release forecasts of their earnings ahead of official detailed reports to help guide investors. Samsung's latest forecast, released on Tuesday ahead of its full results due later in July, comes as demand for semiconductors continues to outstrip supplies - which has pushed up prices . Samsung said in the preview, known as earnings guidance, that it brought in around 171tn won of sales during the quarter, more than double the amount for the same period last year.
