Two publishers brought popular scientific books to the market earlier this year, so that the interested layman could simply help to deepen and broaden his knowledge of the current scientific state of affairs. One answers over 100 urgent questions, the other allows nearly 200 scientists to write and explain their most important scientific news item. The questions and the news stories both stem from 2015, but that does not matter. The vast majority has lost nothing to actuality.

Almost daily, newspaper readers get a number of new scientific findings. A remarkable nutritional advice, for example, or a promising medicine, or an ominous event that would point to climate change. For the average newspaper reader, it is impossible to judge whether this is really important, or that the proverbial storm is in a glass of water.

"Scientific pearls" (Know This) wants to offer handles. The composer of the bundle is the American science journalist John Brockman. He is also the administrator of the Edge website, a discussion center for writers, scientists and philosophers. To the most influential scientists and thinkers he has asked the question about what they think is the most interesting and important recent scientific news.
