The whole premise revolves on a secret war, wherein summons and masters battle to the last for the mythic holy grail. A bombardment breached the walls, and French regulars, wearing heavy woolen bags over their upper bodies to protect them against musket balls, stormed inside using grenades against the fortified houses.

European Inventor Award on Facebook. Dengue fever is an excruciatingly painful — and sometimes fatal — disease that affects millions of people each year. The culprit behind its spread is a mosquito that has proven tricky to keep in check. That is until now. British scientist Luke Alphey has come up with a way to use the mosquito as a tool to control its own species.

With successive releases, the invasive mosquito population is reduced, leading to fewer biting mosquitos and lower risk of disease transmission. After malaria, dengue fever is the second-most widespread mosquito-borne disease in the world. The World Health Organization WHO estimates that every year, between 50 and million people suffer, and about 25, die, from the disease. Worse still, the rate of new infections is rising.

Since the s, the number of countries affected by dengue outbreaks has risen tenfold, making dengue the fastest growing mosquito-borne disease in the world. One of the biggest problems facing public health officials is that there is currently no cure for dengue, nor any way to protect a population from getting sick in the first place. An effective vaccine has so far proven elusive because dengue is caused by four different types of the virus.

In fact, when someone becomes infected with one strain of the virus, they actually increase the risk of developing a more severe form of the illness if they are infected with another strain later in life.
