From this week, researchers worldwide can follow the flow of rivers and height of lakes across the African continent from the comfort of their desks. A new web-based demonstration launched to coincide with this weeks TIGER Workshop makes Envisat-derived altimetry data for African inland water freely available in near-real time.
Envisats Radar Altimeter-2 (RA-2) sensor fires around 1800 radar pulses a second down to the surface of the Earth, then measures very precisely how long it takes for those pulses to bounce back. This travel time can be used to calculate the height of the Earths oceans, ice masses, land surfaces, and also – thanks to a sophisticated algorithm developed by the UKs De Montfort University (DMU) in Leicester under ESA contract – previously elusive results for rivers and lakes flowing over land.
The effort to develop the River and Lake product was led by Professor Philippa Berry of DMUs Earth and Planetary Remote Sensing Laboratory: "Monitoring of water resources is vital over Africa, to enable best use of this precious commodity. Until now reliable information has been difficult to access because of the high cost in equipment, manpower and communications, and because it is difficult to obtain these precious hydrological data from many countries.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
