New radar analysis method can improve winter river safety

University of Alaska Fairbanks researchers have developed a way to use radar to detect open water zones and other changes in Alaska's frozen rivers in the early winter. The approach can be automated to provide current hazard ...

Study uses thermodynamics to describe expansion of the universe

The idea that the universe is expanding dates from almost a century ago. It was first put forward by Belgian cosmologist Georges Lemaître (1894–1966) in 1927 and confirmed observationally by American astronomer Edwin Hubble ...

Hydrogen recombination found to be most plausible explanation for high levels of energy in stellar superflares

Although their primary purpose is to look for exoplanets, observatories like the Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS) have supplied a vast amount of data on stellar flares, detected ...

Designing a cost-effective X-ray free electron lasers facility

Many advances in structural science since the 1970s were made by probing materials with synchrotron radiation: that is, high energy X-rays generated through accelerating high-energy electrons. The latest generation of such ...

Nukes in space: A bad idea in the 1960s, an even worse one now

The US and Japan are sponsoring a resolution for debate by the United Nations security council which—if passed—will reaffirm international commitments to the 1967 outer space treaty (OST) forbidding the deployment and ...
