Towards low-impact high-yielding cows

Burps, behaviour, blood and milk are some of the traits that can give us an indication of how efficient and eco-friendly a cow is. Scientists at Aarhus University are developing tools that can identify the most cost-effective cows. This will benefit the farmer’s economy and the environment.

Atlas of thoughts

Using a computer game, a research group at Aarhus University has found a way to gain deeper insight into the human thought process. The results have amazed the research director, who has discovered a kind of ‘atlas of thoughts’. And that is not all. The group can also reveal which gender is best at solving quantum problems.

Ion trapping takes place in combination with a Hyper-EBIT (electron beam ion trap) and a cryogenic ion trap via three steps. The electrons are first ‘peeled off’ atoms in the Hyper-EBIT, where the ions are also extracted and trapped. In the next step, collections of ions are passed through a vacuum tube, where they are slowed down and made ready for the final step. Here the ions are carefully selected and passed into a cryogenic ion trap – CryPTEx – which in essence was designed by Michael Drewsen’s group. In this trap, the highly charged ions (HCIs) are met by singly charged beryllium ions that are laser cooled. Via the Coulomb interaction between the two types of ions, kinetic energy is removed from the HCI, which finally becomes part of a Coulomb crystal and is ready to undergo ultraprecise spectroscopic measurements.

When quantum neighbours ‘sneak in’

During the last decade, physicists throughout the world have developed and refined laser spectroscopy research to such an extent that it is now possible to carry out experiments with just one atom or molecule. A group involving Danish researchers has now created the basis for extending this research to a completely new class of atomic systems,…
