Researchers at the University of Cambridge Graphene Center have found that through the use of graphene, hard disk drive storage capacity could be increased ten-fold. A standard hard drive consists of platters covered in carbon-based overcoats (COCs) for protection and over the years, the thickness has been reduced from 12.5nm to 3nm, resulting in a data density of 1TB per square inch. By replacing these layers with graphene, they discovered that it’s possible to greatly increase data density. Read more for a video on graphene and additional information.

NVIDIA is working on a 3D map of the universe in an aim to probe subatomic interactions for green energy sources and much more. The team will use Perlmutter at the National Energy Research Scientific Computing Center (NERSC), a supercomputer that will deliver nearly four exaflops of AI performance. What this means is that it’s now the fastest system on the planet on the 16- and 32-bit mixed-precision math AI uses, fully utilizing the 6,000+ Nvidia A100 Tensor Core GPUs. Read more for two videos and additional information.

Could we be getting closer to developing the technology required to build a time machine? Possibly, as scientists from the Moscow Institute of Physics and Technology (MIPT), along with colleagues in Switzerland as well as the US, have managed to reverse the direction of time with a quantum computer. Simply put, it was made from electron “qubits,” or a unit of information described by a “one”, a “zero”, or a mixed “superposition” of both states. Read more for a video and additional information.

Alphabet Inc. subsidiary Google wants to build a practical quantum computer by the end of this decade that could potentially be used commercially to handle large-scale scientific and business calculations with an exponentially higher efficiency without errors. To accomplish this task, they are aiming to build error-corrected logical qubits, or a collection of physical qubits stable enough to hold quantum information for a long period of time, that together form a single logical qubit.
