Groundbreaking research reveals that trauma from violence can leave genetic imprints that pass through generations, as demonstrated in Syrian families affected by civil conflicts. The study found 14 distinct genomic modifications in grandchildren of Hama massacre survivors, providing the first human evidence of transgenerational stress transmission. These findings suggest violence-induced epigenetic changes may influence health outcomes and explain intergenerational cycles of trauma.
A critique of the current web browser ecosystem discusses how complex web standards create barriers for new browser engines, suggesting a simplified WASM-based alternative. The proposed solution advocates for a browser that runs WASM blobs without HTML, JavaScript, or CSS, potentially enabling more innovation and diversity in browser development.
Engineers worldwide mobilized to create low-cost ventilators in response to anticipated COVID-19 demands, with organizations like NASA's JPL, Virgin Orbit, and gaming PC maker Maingear developing prototypes in days. While the immediate crisis was averted through social distancing measures, questions remain about the future utility and safety of these rapid-response ventilators, particularly in developing countries.
Scientists propose that wolves may have domesticated themselves into dogs by choosing to stay near humans for food and selecting mates with similar tameness preferences. A new statistical model demonstrates this self-domestication could have occurred over 15,000 years through natural selection, challenging previous assumptions about human-driven domestication.
Mathematical advances in 'landscape function' theory have significantly improved LED light bulb efficiency, leading to substantial energy savings in US households. The technology enables more accurate simulation of LED designs, particularly helping solve the 'green gap' problem through V-shaped defects in semiconductor layers. US consumers are projected to save $890 billion by 2035 through LED adoption.
Princeton Engineering researchers demonstrated AI's ability to design complex wireless chips in hours instead of weeks, creating more efficient designs that humans find difficult to comprehend. The AI-generated chips, focusing on millimeter-wave technology, achieved superior performance by taking unconventional approaches and discarding traditional templates. While promising, the process still requires human oversight to address potential design failures.
BYD has produced its first solid-state battery cells on a pilot line in 2024, with mass demonstration expected around 2027 and large-scale production after 2030. The company is focusing on sulphide electrolytes for solid-state cells, aiming to achieve cost parity with current NCM cells at scale. BYD plans to use these batteries primarily in high-end models while maintaining LFP cells for other vehicle segments.
Half-Life, released in 1998 by Valve, revolutionized first-person shooters by seamlessly integrating story and gameplay without cutscenes, creating an unprecedented level of immersion. Founded by former Microsoft employees Gabe Newell and Mike Harrington, Valve's ambitious approach and deep pockets allowed them to develop a game that would influence game design across genres for decades to come.
An analysis debunking claims about extremely high IQ scores (160+) reveals that such measurements become increasingly unreliable and meaningless at higher ranges. Historical genius figures like Einstein likely had more modest IQs around 120-130, with test scores being highly variable and practice-dependent. The correlation between IQ and real-world outcomes diminishes significantly beyond certain thresholds.
An exploration of why hiring junior engineers is crucial for innovation and organizational health, emphasizing how coaching junior employees creates a culture of learning and psychological safety. The article argues against the trend of companies only hiring senior developers, highlighting how teaching and knowledge sharing are essential for innovation and challenging the notion that AI will replace junior developers.
