Portrait: Lord of the rings
As a child, Jens Stadlmann enjoyed tinkering with bicycles, and today he takes care of the particle-accelerator facilities at the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt. For this purpose he arrives sometimes in the control room at two A.M. and fiddles about with technical problems.
Carbon dating: Is the radiocarbon clock still set properly?
Entire scientific worldviews count on its reliability. Research scientists determine the age of carbon-based materials such as bones, wood, ceramics, textiles and iron using the radiocarbon method. But man-made CO² emissions could weaken the informative value of the method.
HELMHOLTZ extreme: The Coldest Place in the Universe
Actually, it is not out there somewhere among the innumerable heavenly bodies of outer space - the coldest place in the universe is right here in research laboratories on Earth.
Can computers read minds?
By now computers are capable of converting spoken words into text. But can they also read minds? A computer scientist has an answer.
Rivers: Predicting water levels through data analysis
It has only been possible thus far to reliably predict the water level of rivers a few days in advance. Scientists are now developing, with the aid of ocean and climate data from the last six decades, a calculation model that enables longer term predictions.
