“LSM-TS provides annual global estimates of ambient population from 1975–2024 at ~90 m resolution, creating a spatially and temporally consistent reconstruction of population change designed for longitudinal analysis. Reconstruction of historical populations are driven by current LandScan Mosaic building-level population distributions, scaled by built-surface change from #GHSL … and calibrated to annual national-level estimates from U.S. Census Bureau…”

“LandScan is a globally recognized, R&D100-winning population data platform developed at Oak Ridge National Laboratory (ORNL). Its datasets provide human population distribution estimates down to 100 meter grid resolution. LandScan supports disaster response, humanitarian aid, environmental analysis, and urban planning by providing insights into where people live and how they move…”

“Gridded population data support assessments of human exposure, settlement change, infrastructure demand, and access to services, yet global datasets combining annual coverage over multiple decades with fine spatial resolution remain limited. LandScan Mosaic Time Series provides 50 annual estimates of global ambient population distribution at 3 arc-second resolution from 1975 through 2024. The series is anchored to the 2024 LandScan Mosaic surface, produced through a building-level population modeling workflow. Historical surfaces are reconstructed using annualized changes in built surface and derived first-level administrative population trajectories. Every layer, including 2024, is normalized to administrative targets scaled to annual country totals from the U.S. Census Bureau International Database. The dataset is distributed as 50 single-band Cloud Optimized GeoTIFFs on an identical WGS84 grid, with values representing estimated persons per cell. Its common grid and methodology support fine-scale longitudinal analysis of ambient population distribution while documented validation and limitations guide appropriate reuse…”

#OakRidge spawns institute to curb #AI #datacenter power surge
#ORNL aims to link power, cooling, and workload management to ease strain on the US grid
As an internal "institute within an institute," NGDCI aims to bring together the laboratory's facilities and expertise spanning energy, high-performance computing, cybersecurity, and grid technology. The ultimate goal is to ensure that #America's rapidly growing AI infrastructure remains secure, efficient, and reliable.

#Trump's rush to build #nuclear reactors across the U.S. raises safety worries
December 17, 2025
"Critics, however, worry that the tight July 4 deadline, political pressure and a lack of transparency are all compromising safety. Even a 'small' release of #radioactive material could cause damage to #people and the #environment around the test sites.
"This is not normal, and this is not OK, and this is not going to lead to success," warned #AllisonMacfarlane, a professor at the University of British Columbia who served as chairman of the #NRC under President Barack Obama. 'This is how to have an accident.' "

A study by #MIT and #OakRidge National Laboratory found that #AI can already #replace 11.7% of the U.S. #labourmarket, equating to $1.2 trillion in wages. The Iceberg Index, a #laboursimulation tool, was used to analyse how AI impacts tasks, skills, and labour flows across the country. The index provides a detailed map of potential #jobdisplacement, helping policymakers prepare for AI’s impact on the #workforce. https://www.cnbc.com/2025/11/26/mit-study-finds-ai-can-already-replace-11point7percent-of-us-workforce.html?AIagents.at #AIagent #AI #ML #NLP #LLM #GenAI

The #exascale offensive: #America's race to rule #AI #HPC
DOE's audacious plan will deploy nine cutting-edge #supercomputers across #Argonne, #OakRidge, and #LosAlamos National Labs through unprecedented public-private partnerships. Scale is staggering: systems bristling with hundreds of thousands of next-generation processors, capable of quintillions of calculations per second purpose-built to unlock AI applications – and to ensure America's rivals don't get there first.

Opinion | Trump Is Squandering the Greatest Gift of the Manhattan Project – The New York Times

How Trump Is Undoing 80 Years of American Greatness
Aug. 12, 2025 A Manhattan Project development site in Oak Ridge, Tenn., in 1944. Credit…Chicago History Museum/Getty Images Listen to this article · 7:42 min Learn moreBy Garrett M. Graff
Mr. Graff is a journalist, a historian and the author, most recently, of “The Devil Reached Toward the Sky: An Oral History of the Making and Unleashing of the Atomic Bomb.”
阅读简体中文版閱讀繁體中文版The 80th anniversary last week of the atomic bombings that helped end World War II came at a most peculiar time. That is in part because we can’t mark that anniversary without also noting the astonishing Manhattan Project that built atomic weapons.
The Manhattan Project was a towering achievement, one of the great stories of human effort and accomplishment. Yet the Trump administration has been systematically dismantling the culture of research that the Manhattan Project and World War II bequeathed us, a culture that propelled American prosperity.
At no other time in modern history has a country so thoroughly turned its back on its core national strengths. The very elements that made the Manhattan Project such a success are today under assault. With devastating cuts to science and health research, the administration is turning its back on a history of being powered and renewed by the innovation and vision of immigrants. What America may find is that we have squandered the greatest gift of the Manhattan Project — which, in the end, wasn’t the bomb but a new way of looking at how science and government can work together.
That the Manhattan Project happened is itself a minor miracle. For nearly two years, the U.S. military seemed to want nothing to do with the effort of inventing an atomic bomb.
From 1939 to 1941, a ragtag group of mostly Jewish refugee scientists from Hitler’s Europe, including Albert Einstein, approached the government and met with military officials. The scientists educated them on the discovery of nuclear fission, its implications for war and their fears that Hitler would develop an atomic bomb first.
The military brushed them off. “The colonels kept rather aloof,” the physicist Eugene Wigner recalled after one such meeting in October 1939, as Hitler took Poland. “They were friendly, they smiled, but they never expected to see a working atomic bomb in this world.”
One of those colonels told Wigner and Edward Teller, dismissively, that he would award $10,000 to whoever could develop a death ray and prove it by killing a goat — the implication being he imagined that project more likely than a bomb that unlocked the power of the fundamental building block of the universe.

#Tennessee state Rep. #JohnRagan *represents* #OakRidge , but he *demonstrates* the mentality of the new #Trump -ruled #GOP (Grievances Only Party).

Scientists in China are now building on the same basic MSR technology developed at ORNL. The Chinese gov’t had a small, short-lived knowledge exchange program with ORNL. But most of the…intellectual property…is in the public domain.
“The real data mine is the thousands of published reports in 1960s and '70s that are found in the open literature," Forsberg says.
