2024년 대기 중 CO₂ 농도는 약 426ppm에 도달했으며, 이는 산업화 이전 대비 약 50% 높은 수치입니다. UC 버클리 연구진은 아연 수소화물 MOF인 ZnH-MFU-4_l을 개발하여 300°C의 고온 연도 가스에서 90% 이상의 효율로 CO₂를 포집할 수 있게 했으며, 이는 굴뚝에 직접 통합할 수 있는
SMR은 최대 300 MWe의 전력을 생산하는 소형 모듈 원자로로, 부품을 공장에서 제조해 현장에서 조립하는 모듈식 설계다. 일반적으로 4, 6, 12개의 모듈을 병렬로 설치해 필요에 따라 용량을 확장할 수 있다. 미국 원자력규제위원회(NRC)는 2020년 NuScale의 50 MWe 경수로 설계 인증을 승인했다. NuScale의 77 MWe
November 23, 2025, 2:48 AM EST. At a parliamentary hearing, former Lowell state representative David Nangle testified against proposed internet gaming (iGaming) legislation, warning that legalizing online casino gambling could fuel addiction. Nangle, who served prison time on campaign-finance and debt-related charges, argued that iGaming is not progress but a gateway to harm. Lawmakers, including Rep. David Muradian Jr., introduced H 4431 to regulate internet gambling, allowing the state's three casinos-Plainridge Park, MGM Springfield, and Encore Boston Harbor-to offer up to three online brands or skins apiece under the purview of the Massachusetts Gaming Commission. The bill would set age limits, geolocation, and verification requirements to bring online gambling out of the shadows. Meanwhile, the state's iLottery efforts and ongoing policy debate leave questions about how far to expand gaming and whether new revenue would offset costs without raising taxes.

November 23, 2025, 2:44 AM EST. President Donald Trump is exploring an executive order to pressure states to stop regulating AI and to withhold federal funding or sue to block state laws. The draft order would spur a lighter, nationwide framework to override state AI rules. Some in Congress seek a temporary block on state AI laws. Proponents say current state regulations risk stifling innovation and could lag behind rapid tech advances. Critics warn it would shield big AI firms from scrutiny and undermine civil liberties, data privacy, and consumer protections. So far, Colorado, California, Utah, and Texas have enacted targeted AI measures on transparency and risk assessments; other rules ban deepfakes in elections or govern government use of AI. The draft order is not final.
November 23, 2025, 2:42 AM EST. Investor Michael Burry questions Nvidia's capital allocation, arguing that roughly $112.5 billion in stock buybacks since 2018 produced little to no shareholder value. In a post on X, he notes Nvidia's rising share count and about $20.5 billion in stock-based compensation (SBC) since 2018, suggesting buybacks mainly offset SBC dilution. He contends the true cost is reflected in diminished owner's earnings. Nvidia, meanwhile, reports a booming period of AI-driven demand, with $57 billion quarterly revenue and expectations of hundreds of billions in revenue from Blackwell and Rubin GPUs, and continued buybacks per guidance. CFO Colette Kress emphasizes a strong balance sheet, while CEO Jensen Huang cites ecosystem investments (OpenAI, Anthropic) and CUDA expansion. Nvidia stock has outperformed broader markets and remains a core AI leader.
November 23, 2025, 2:40 AM EST. Advocacy group Fairplay warns that AI toys can undermine child development and raise safety risks, urging parents not to gift them this season. Many toys feature embedded AI chatbots (often powered by OpenAI's ChatGPT), and partnerships with toy makers like Curio, Loona, and Mattel amplify exposure. Critics note that even with safeguards, chatbots can be misused or provide harmful content; tests by U.S. PIRG found toys sometimes engage in explicit conversations or emotional manipulation. High-profile incidents, including reports around Grok and a teen's interaction with ChatGPT, underscore ongoing safety concerns. With evolving guardrails and uncertain outcomes, the guidance is to avoid AI-enabled toys for kids and keep consumer tech on the shelf.
