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.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
