The missing trillions
(University of Sussex) The hidden social, environmental and health costs of the world’s energy and transport sectors is equal to more than a quarter of the globe’s entire economic output, new research from the University of Sussex Business School and Hanyang University reveals.
Climate change will lead to more extreme weather events. Is Texas prepared? – Austin American-Statesman
Freezing temperatures for nearly a week, with lows dipping into the single digits. Sheets of ice covering roads. Snowfall blanketing much of the state, totaling 15 inches in some areas. The historic winter weather that swept across Texas in February — crippling infrastructure…
What is a quasar?
A quasar is an extremely bright and distant point-like source visible to radio telescopes. The source is a so-called Active Galactic Nucleus, fueled by a supermassive black hole.
Cosmic ray originated in cataclysmic event
Astronomers found a high energy neutrino – a cosmic ray – that apparently originated during a “tidal disruption event,” that is, when a supermassive black hole shredded a distant star.
Atlantic ‘Conveyer Belt’ Shows No Sign Of Slowing, Scientists Find
A 30-year reconstruction of the Atlantic meridional overturning circulation shows no decline. It’s the very same scenario posed in the disaster movie “The Day After Tomorrow,” where a slowdown in the Gulf Stream turned North America into a frozen wasteland….
Why does this galaxy look older than its years?
To the extent that we can see them, galaxies in the very early universe should look relatively young and unformed. But galaxy ALESS 073.1 is a surprise to astronomers: it looks more mature than we’d have any reason to expect. Why?
Getting ahead of climate change
(SPIE–International Society for Optics and Photonics) In “Perspectives on flood forecast-based early action and opportunities for Earth observations,” Claire Nauman et al. focus on flood forecasts and identify opportunities to incorporate Earth observation data into flood forecast-based early action.
Nearby black hole Cyg X-1 more massive than thought
New research suggests that the famous black hole Cygnus X-1 – first black hole ever detected and one of the closest to Earth – is farther away and much more massive than previously believed.
Tool that more efficiently analyzes ocean color data will become part of NASA program
(Stevens Institute of Technology) Researchers at Stevens Institute of Technology have developed a new machine learning-powered platform, known as OC-SMART, that can process ocean color in satellite images 10 times faster than the world’s leading platform. The work, which will be adopted by NASA, is one of the first machine learning-based platforms in ocean color analysis that can process both coastal and open ocean regions globally to reveal data on sea health and the impact of climate change.
