By Heidi Ledford of Nature magazine At last, a member of the celebrated sirtuin family of proteins has been shown to extend lifespan in mammals -- although it's not the one that has received the most attention and financial investment. Sirtuin genes and the proteins they encode have intrigued many researchers who study ageing ever since they were first linked to longevity in yeast.

(PhysOrg.com) -- Superconductivity is a rare physical state in which matter is able to conduct electricity -- maintain a flow of electrons -- without any resistance. This phenomenon can only be found in certain materials at low temperatures, or can be induced under chemical and high external pressure conditions. Research to create superconductors at higher temperatures has been ongoing for two decades with the promise of significant impact on electrical transmission.

A new phenomenon might make computing devices faster, smaller and much more energy-efficient. Moving so-called skyrmions needs 100,000 times smaller currents than existing technologies and the number of atoms needed for a data bit could be reduced significantly. Now a team of physicists from the Technische Universitaet Muenchen and the University of Cologne developed a simple electronic method for moving and reading these skyrmion data bits
