Deadly air case truly a matter of life or death 13 May 2021 – In early 2003, landmark litigation was brought by the Treatment Action Campaign against the government. The TAC confronted the government for not providing proven and cost effective medicines for prevention of mother-to-child transmission of HIV to pregnant mothers. It won the court case on the basis of the constitutional guarantee of the right to health care, and the government was ordered to start programmes for prevention of mother-to-child-transmission of HIV in public health facilities.

Genius Maintenance Secrets of Aqueduct of Constantinople Revealed

Over time, these chalky white deposits can build up on rock, brick,  concrete, or metal surfaces where water runs. The longer water runs through a copper pipe, for example, the more calcium carbonate deposits will build up inside. Eventually, they can become so thick that water flow is restricted or blocked altogether, at which point a plumber will need to be summoned to clean the pipes.  Limescale buildup could be a problem in  aqueducts, too. The spring water harvested for aqueduct transport would have picked up dissolved deposits of calcium carbonate from limestone and other surrounding rocks. When passing through aqueduct channels, it would have left behind a trail of limescale. The continuous flow of water could have resulted in significant limescale accumulation over the years.

A beetle s Achilles heel

Credit: Julian Kiefer, Johannes Gutenberg-Universität Mainz Saw-toothed grain beetles live in a symbiotic association with bacteria. Their bacterial partners provide important building blocks for the formation of the insect s exoskeleton, which protects the beetles from their enemies as well as from desiccation. In a new study, a team of scientists from the Johannes Gutenberg University in Mainz, the Max Planck Institute for Chemical Ecology in Jena, and the National Institute of Advanced Industrial Science and Technology in Japan demonstrates that glyphosate inhibits the symbiotic bacteria of the grain beetle. Beetles exposed to the weedkiller no longer receive the building blocks they need from the bacteria. The study shows that glyphosate has the potential to harm insects indirectly by targeting their bacterial partners and thus to contribute to their decline (
