A study conducted by an expert at the University of Sheffield and officials at NASA has found that while Greenland’s ice is certainly thinning, snowfall in some areas is increasing, with levels in south-east Greenland in the past year being three times higher than is usual. This opens debate as to how global warming will affect Greenland’s ice sheet and could mean that it remains stable, as thinning ice is offset by increased snowfall, which will replace the melted ice.
Edward Hanna, from the University of Sheffield’s Department of Geography explains, “Our study involved using airborne laser surveys to measure the height of the ice in Greenland. We found that ice is thinning at an extremely rapid rate along the margins, meaning that Greenland’s contribution to global sea level rise has almost doubled since the mid 90s.
“In contrast to this, ice in South East Greenland has actually thickened by a metre between 2002 and 2003, reversing the thinning of between 10cm and 40cm a year which had been occurring there in the mid 90s. This sudden thickening was due to unusually high levels of snowfall between 2002 and 2003. Usually this area would experience about a metre of snow per year, but in this period 3m of snow fell, which is the highest rate in more than 45 years of meteorological data.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
