Guest Author Mar 14, 2022

Daniella McCahey, Texas Tech University When the wreck of Ernest Shackleton’s ship Endurance was found nearly 10,000 feet below the surface of Antarctica’s Weddell Sea in March 2022, it was located just 4 miles from its last known position, as recorded by the Endurance’s captain and navigator, Frank Worsley, in November 1915. That’s an astonishing degree of accuracy for … Read More

Exploring Antarctica’s hidden under-ice rivers and their role in future sea-level rise - The Changing Climate

Guest Author Feb 14, 2022

Huw Joseph Horgan, Te Herenga Waka — Victoria University of Wellington and Craig Stevens, National Institute of Water and Atmospheric Research Underneath Antarctica’s vast ice sheets there’s a network of rivers and lakes.

Anti-neutrinos–When you are your own opposite - Physics Stop

Marcus Wilson Nov 28, 2019

Around a million billion pass through you each second, almost all originating from our sun, but few of them are likely to interact with you enroute. I was reading in a physics magazine earlier in the week about the nature of neutrinos. These are extremely numerous elementary particles, but only interact very weakly with anything.  A typical neutrino will travel … Read More
