(University of Cambridge) Training the artificial intelligence models that underpin web search engines, power smart assistants and enable driverless cars, consumes megawatts of energy and generates worrying carbon dioxide emissions. But new ways of training these models are proven to be greener.
(University of Oregon) Long-running archaeological research, boosted by airborne lidar sensing and machine-learning algorithms, finds that Cambodia’s Greater Angkor region was home to 700,000-900,000 people. The new estimate, made possible by a study designed at the University of Oregon, is the first for the entire 3,000-square-kilometer low-density region.
(West Virginia University) As WVU’s latest NSF CAREER Award winner, Assistant Professor of Geography Aaron Maxwell will use big data to map what the surface of West Virginia looked like over the last 60 years. The funding includes $636,785 over five years.
(DOE/Oak Ridge National Laboratory) Sergei Kalinin, a scientist and inventor at the Department of Energy’s Oak Ridge National Laboratory, has been elected a Fellow of the Microscopy Society of America professional society.
(University of Iowa) The famed northern and southern lights have been studied for millennia, but they still hold secrets. In a new study, physicists led by the University of Iowa describe a new phenomenon they call “diffuse auroral erasers,” in which patches of the background glow are blotted out, then suddenly intensify and reappear.
(Texas A&M University) The introduction of lithium-ion (Li-ion) batteries has revolutionized technology as a whole, leading to major advances in consumer goods across nearly all sectors. Battery-powered devices have become ubiquitous across the world. While the availability of technology is generally a good thing, the rapid growth has led directly to several key ethical and environmental issues surrounding the use of Li-ion batteries.
The Antarctic ice sheet is much less likely to become unstable and cause dramatic sea-level rise in upcoming centuries if the world follows policies that keep global warming below a key 2015 Paris climate agreement target, according to a Rutgers…
Catastrophic Sea-Level Rise from Antarctic Melting is Possible with Severe Global Warming – Rutgers Today
Antarctic ice sheet is more likely to remain stable if Paris climate agreement is met If Paris Agreement targets are not met, the collapse of melting Antarctic ice shelves – like the Wilkins Ice Shelf in 2009 – could cause…
(Yale University) Mastery of fire has given humans dominance over the natural world. A Yale-led study provides the earliest evidence to date of ancient humans significantly altering entire ecosystems with flames.
The hydrogen that accounts for around 10 per cent of our body mass was formed 13.8 billion years ago
