A new method for dating ancient sea shells reveals that the Greenland Ice Sheet was smaller between 3,000 and 5,000 years ago than it is today. The new study also indicates that the inland ice is more robust than previously thought.
A new, superconducting oxide system multiplies the electron mobility in electronic oxide transistors. Benefits include superconducting nanotransistors, self-charging electronic devices and a new type of RAM.
The supercomputer of the future operates with quantum bits, but quantum systems are fragile and they degrade easily. Now Danish scientists have managed to turn this degradation into an advantage, making it easier to create the special quantum states required for a quantum computer.
Research grants are increasingly being awarded to the same few popular research fields. This results in homogenised projects that rarely deliver what they promise. The phenomenon is similar to real estate bubbles, argue two Danish philosophers.
