Buildings, car parks and roads could, alongside their 'regular' functions, have a role to play in protecting the rest of the city from flooding. This concept could be very useful for the Dutch cities along the River Rhine, for example.

Recent research reveals how physical qualities -- and not only chemical ones – may have an influence in determining how adult stem cells from the bone marrow develop into differentiated ones. The finding represents an important step in understanding the mechanisms that direct and regulate the specialization of stem cells from their undefined state.

In order to estimate the safety of final storage for nuclear wastes, it is important to know the half-lives of the radioactive elements of the nuclear waste as accurately as possible. The half-life indicates the period of time in which the amount of a radioactive element decreases by half and breaks down into other atoms. This period of time can, depending on the composition of the nuclear waste, amount to decades or even millions of years.
