An anonymous reader shares a report: The Abu Dhabi Grand Prix draws princes, movie stars and world-famous athletes every year to party on Yas Island, the entertainment hub about 30 minutes from the center of downtown. Mingling among them last month was a figure charting an unlikely ascent: a former McDonald's burger-flipper and software developer who, practically overnight, has vaulted into the ranks of the world's wealthiest people -- cryptocurrency pioneer Changpeng Zhao. CZ, as he's known to cryptophiles, is quickly becoming a fixture in the United Arab Emirates, meeting with royalty in Abu Dhabi who are eager to bring his Binance exchange to the country, according to people with knowledge of the situation. He has scooped up an apartment in Dubai and hosted dinners near the Burj Khalifa, the world's tallest building, and on the city's Palm Jumeirah island -- making him the most prominent personality in the nation's booming crypto scene.

In a region known for dizzying wealth, Zhao, 44, fits right in: His net worth is $96 billion, according to the Bloomberg Billionaires Index. It's the first time Bloomberg has estimated his fortune, which exceeds Asia's richest person, Mukesh Ambani, and rivals tech titans including Mark Zuckerberg and Google founders Larry Page and Sergey Brin. Zhao's fortune could be significantly larger, as the wealth estimate doesn't take into account his personal crypto holdings, which include Bitcoin and his firm's own token. Binance Coin, now called BNB, surged roughly 1,300% last year. Binance's success underscores the vast riches being created in the unshackled cryptoverse, even with recent declines, but controversy has swirled around the firm. Banished from China -- where it was founded -- the company faces regulatory probes globally. The U.S. Department of Justice and Internal Revenue Service are investigating whether one entity Zhao controls, Binance Holdings, is a conduit for money laundering and tax evasion, according to people with knowledge of the matter.

An anonymous reader quotes a report from CNN: Building walls on the seafloor could prevent glaciers from melting and sea levels rising due to global warming, scientists say. Barriers of sand and rock positioned at the base of glaciers would stop ice sheets sliding and collapsing, and prevent warm water from eroding the ice from beneath, according to research published this week in the Cryosphere journal, from the European Geosciences Union. The audacious idea centers on the construction of "extremely simple structures, merely piles of aggregate on the ocean floor, although more advanced structures could certainly be explored in the future," said the report's authors, Michael Wolovick, a researcher at the department of geosciences at Princeton University, and John Moore, professor of climate change at the University of Lapland in Finland.

Using computer models to gauge the probable impact of walls on erosion of the Thwaites glacier in Antarctica, one of the world's largest, Wolovick and Moore hoped to test the efficiency of "a locally targeted intervention." They claimed the simplest designs would allow direct comparison with existing engineering projects. "The easiest design that we considered would be comparable to the largest civil engineering projects that humanity has ever attempted," they said. "An ice sheet intervention today would be at the edge of human capabilities." For example, building four isolated walls would require between 0.1 and 1.5 cubic km of material. "That is comparable to the 0.1 km3 that was used to create Palm Jumeirah in Dubai ($12 billion)...(and) the 0.3 km3 that was used to create Hong Kong International Airport ($20 billion)," the report said. The authors say there's only a 30% probability of success due to the harsh environment, but did mention that the scientific community could work on a plan that was both achievable and had a high probability of success.
