source:EurasiareviewAccording to an estimate of IBM the current daily production of digital information exceeds 2.5 quintillion bytes (equivalent to about 50 million of dual-layer Blu-ray discs, which stacked on top of each other would be 60 km high) and continues to grow at a staggering rate.The vast majority of this data is stored magnetically, where a binary bit, 0 or 1, corresponds to opposite magnetization directions, and is nowadays typically written or erased by current-driven electromagnets. As this process poses fundamental limitations with regards to speed and energy efficiency, the ...

source:RFIRecently developed quantum technologies are the forefront of computing and could revolutionise the fields of computing and communications. Thanks to their unique capabilities, quantum computers can either solve algorithms that classical computers cannot solve or significantly reduce computation time.ADVERTISINGHowever, implementing the principles of quantum mechanics to build a workable quantum computer remains a big challenge.A big part of that challenge is to find the right material that can enable the full potential of the quantum properties. Now, research teams from France a...

source:EASTASIAFORUMFor member states of the Regional Comprehensive Economic Partnership (RCEP) its signing, ratification and being in effect are by no means the final goal. RCEP is designed in the ‘ASEAN Way’, meaning members must make it a living and evolving agreement if it is going to help successfully defend the rules-based trading regime. In particular, continuous commitment to RCEP by non-ASEAN member states will be key.Recent policy debates in countries including Japan have been dominated by geopolitics. Discussions of economic statecraft and economic security have taken centre stage a...

High-precision tumor resection down to few-cell level guided by NIR-IIb molecular fluorescence imaging source:PNASSurgical removal of tumors has been performed to combat cancer for over a century by surgeons relying on visual inspection and experience to identify margins between malignant and healthy tissues. Herein, we present a rare-earth down-conversion nanoparticle–anti-CD105 conjugate for cancer targeting and a handheld imager capable of concurrent photographic imaging and fluorescence/luminescence imaging. An unprecedented tumor-to-muscle ratio was achieved by near-infrared-IIb (NIR...
