Fabled equatorial icecaps will disappear within two decades because of global warming, a study led by UCL (University College London) has found.
Reporting online in the journal Geophysical Research Letters, the first survey in a decade of glaciers in the Rwenzori Mountains, East Africa, has found that an increase in air temperature over the last four decades has contributed to a substantial reduction in glacial cover.
The Rwenzori Mountains - also known as the Mountains of the Moon - straddle the border between the Democratic Republic of Congo and the Republic of Uganda. They are home to one of four remaining tropical ice fields outside of the Andes and are renowned for their spectacular and rare Afroalpine flora and fauna. The mountains legendary status was established during the 2nd century when the Greek geographer Ptolemy made the seemingly preposterous but ultimately accurate proclamation that the River Nile was supplied by snow-capped mountains at the equator in Africa: "The Mountains of the Moon whose snows feed the lakes, sources of the Nile".

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
