Google Enters Massive 3.6-GW Power Deal With Constellation Energy

An anonymous reader quotes a report from Reuters: Google has contracted for 3,590 megawatts of power from Constellation Energy on the largest US power grid, with new nuclear energy accounting for about a quarter of that supply, the companies said on Tuesday. Constellation will make more than $4.3 billion of new investments in its fleet as part of the agreement, which involves adding capacity at several of the power company's nuclear reactors in the Midwest and Mid-Atlantic regions, the companies said. [...] Over the last two years, Constellation unveiled an agreement to restart its Three Mile Island reactor in Pennsylvania to serve Microsoft data centers, while Google contracted to restart NextEra Energy's nuclear power plant in Iowa. In the latest arrangement, Google entered into a 20-year power purchase agreement for 890 megawatts of electricity from multiple Constellation-owned nuclear power plants, which would be upgraded to produce more electricity from existing reactors. Electricity from the first of the upgraded plants is expected to be delivered in 2028, the companies said. Google also entered into a 15-year supply agreement for an additional 2,700 megawatts of power from Constellation in the PJM power grid. That power is not tied to a specific generation source and serves as long-term revenue certainty for Constellation's operating plants, Google said. Maryland-based Constellation is the largest US nuclear power plant operator and owns a major fleet of natural-gas-fired power plants as well as geothermal energy following its acquisition of electricity producer Calpine Corp earlier this year. [...] The 11 nuclear units expected to be upgraded as part of the arrangement with Google are in Illinois, Pennsylvania, and New Jersey, within the footprint of the largest US electric grid -- PJM Interconnection. Joe Dominguez, chairman, president and CEO of Constellation, said the arrangement with Google is a "model for how technology companies and the energy industry can work together to responsibly develop the digital economy and invest in our nation's energy infrastructure in a way that delivers grid-wide benefits for all, funded by private entities."

South Korea Says AI Agents May Have Been Used to Hack the Country's Banks

South Korean President Lee Jae Myung says there are signs AI models may have been used in recent cyberattacks against several major banks. "In some hacking incidents, signs have emerged of AI being used, causing considerable public concern and anxiety," Lee said during a cabinet meeting. "Please establish the circumstances swiftly and clearly, and concentrate personnel and resources on minimizing the damage." Reuters reports: South Korea's police have launched a full-scale investigation into the hacking attacks against commercial banks that led to a breach of customers' personal information, the Yonhap news agency reported on Tuesday. Shinhan Bank, KB Kookmin Bank and others had reported cyberattacks, the Financial Services Commission (FSC) said on Friday, while Yonhap reported that Hana Bank and Woori Bank also suffered breaches. Authorities have not yet disclosed details on what kind of AI tools were used in the hacking incidents or the full scale of the breaches. On Sunday, FSC Chairman Lee Eog-weon convened an emergency meeting with financial industry associations, regulators and executives from affected institutions, warning that the sector must respond with the highest level of vigilance. Financial watchdog the Financial Supervisory Service (FSS) and the Financial Security Institute shared data about 28 unique IP addresses and some country information linked to the recent hacking attempts with the financial sector, the FSS said on Tuesday.

Canadian Analysis: Permanent Daylight Saving Harms Sleep and Mental Health

"With the push to eliminate the twice yearly clock change, Permanent Daylight Savings Time has emerged as the favorite for most states and provinces," writes longtime Slashdot reader kbahey, sharing the findings from a recent analysis published in the Canadian Medical Association Journal. Sci.News reports: "Ending the clock change solves one problem, but it creates another decision: which time should we live on year-round?" said University of British Columbia's Professor Raymond Lam, lead author of the study. "The health evidence points to standard time, largely because morning light matters for our body clocks, sleep, and mood." Professor Lam and colleagues examined the health consequences of the two possible permanent systems rather than the broader question of whether seasonal clock changes should be abolished. They concluded that the accumulated evidence favors permanent standard time, which keeps the clock more closely aligned with human circadian biology. This distinction, according to the team, becomes particularly important during winter. Permanent daylight saving time would push sunrise an hour later. In cities such as Toronto, for example, the latest winter sunrise would occur at 8:51 a.m., compared with 7:51 a.m. under permanent standard time. In Calgary, the corresponding times would be 9:40 a.m. and 8:40 a.m. The extra hour of morning darkness could leave people traveling to work or school before sunrise, while shifting more daylight into the evening. The change could have consequences for sleep, mood, learning and productivity, particularly among people who already have difficulty sleeping or who must follow early schedules. The reason is rooted in the body's internal clock. "Our biological clocks need morning light to stay synchronized with the 24-hour day," said Simon Fraser University's Professor Ralph Mistlberger, co-author of the study. "Permanent daylight saving time moves that light an hour later just when winter mornings are already darkest." The analysis also highlights concerns about seasonal depression. [...] By delaying natural morning light, permanent daylight saving time would act in the opposite direction, potentially weakening an important circadian signal.
