The storage capacity of hard drives is increasing explosively, but the speed with which all that data can be written has reached its limits. Researchers present a promising new technology which potentially allows data to be stored 1,000 times as fast. The technology, in which ultra-short laser pulses generate a 'spin current', also opens the way to future optical computer chips.

Protons and neutrons are the basic constituents of atomic nuclei. Are they distributed homogeneously, or perhaps in quartets consisting of two protons and two neutrons? Physicists have recently presented an idea how this issue may be investigated in future experiments.

The first research program is aimed at so-called '7 nanometer and beyond' silicon technology that will address serious physical challenges that are threatening current semiconductor scaling techniques and will impede the ability to manufacture such chips. The second is focused on developing alternative technologies for post-silicon era chips using entirely different approaches, which IBM scientists and other experts say are required because of the physical limitations of silicon based semiconductors.

Read moreResearchers have caught a central step of photosynthesis in action for the first time. The team used the world's most powerful X-ray flashlight to record still frames of a molecular complex called photosystem II as it splits water into hydrogen and oxygen, a process that maintains the oxygen in earth's atmosphere.
