A study published in the Vadose Zone Journal examines how different soil types affect Cryptosporidium parvums transport.
Groundwater is generally considered a safe source of drinking water because pathogens are presumably filtered out during their transport through unsaturated soils. Nevertheless, pathogen-contaminated groundwater has been the cause of many disease outbreaks in the last 10 years including cryptosporidiosis caused by the protozoan pathogen Cryptosporidium parvum. Standard chlorine disinfection is not effective at killing the pathogen.
Although several "crypto" outbreaks have occurred in the U.S., the most severe problem is in Africa where both the sanitary conditions are poor and a significant portion of the population has HIV. It is especially dangerous for people with a compromised immune system because it can lead to severe diarrhea and lethal dehydration. the most notable being a cholera epidemic in London in 1854.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
