    Japan Intervenes in Currency Market, Yen Surges

    The yen exchange rate temporarily surged to around 157 yen per dollar, with market intervention observed. This is the first time in two months that such intervention has been seen. The government and the Bank of Japan are suspected of intervening in the foreign exchange market by buying yen and selling dollars. The yen has appreciated sharply, reaching its highest level in about two months.

    Dollar Plunges Below 160 Yen in New York

    The dollar fell below 160 yen in New York trading on Thursday, its lowest level in about one and a half months. This drop came after the dollar had traded above 163 yen earlier in the day, its highest level in nearly 39 years and eight months. The yen attracted buying after the U.S. Federal Reserve stopped short of raising interest rates at its policy-setting Federal Open Market Committee meeting. Japanese authorities were speculated to have intervened in the market to support the yen.

    Ghost Ancestors' DNA Found in Modern Humans

    A new computational approach has identified human DNA inherited from unknown 'ghost' ancestors. This method, called TRACE, reconstructs ancestral recombination graphs to detect genetic traces of ancient crosses. It revealed two unknown ancestors: one that interbred with modern humans in Africa around 50,000 years ago, contributing around 1% of the modern human genome, and another that interbred with Denisovans in Eurasia, with some of its DNA later shared with modern humans. These findings paint a more complex picture of human evolution, with interconnected populations and repeated episodes of migration and admixture.

    Fire Clouds: How Large Fires Create Thunderstorms

    Large-scale fires can create pyrocumulus-nimbostratus clouds, also known as fire thunderstorms or 'fire clouds'. These clouds form due to intense heat from fires, causing vertical movement of hot air and water vapor, leading to condensation and electrical discharges. The resulting lightning can cause new fire spots, making fires more difficult to control. These phenomena have been observed in recent fires in France and previously in Portugal. The climate crisis contributes to the spread of these fires.

    AMD to Raise GPU Prices by 10% Next Month

    AMD is reportedly planning to increase its graphics card prices by around 10% starting next month, according to hardware leaker Harukaze 5719. This follows Nvidia's recent price increases and is likely due to the ongoing memory crisis driven by AI demand. The price hike could close the value gap between AMD and Nvidia cards, with AMD's flagship Radeon RX 9070 XT potentially reaching similar pricing to competing Nvidia cards.
