To protect networks from malicious threats, cyber-security solutions must track all the data flowing through the network—just like security guards checking travellers in airports. However, it is hard to design a solution that works fast enough to process all the information in real time and to block threats before they can strike. Now, A*STAR researchers have designed a way to structure data that is robust against cyber-attacks and allows it to be processed in record time The team's work improves on widely-used data structures called 'hash tables'. "A hash table maps values to specific locations, labelled with indices," explains Vrizlynn Thing from the A*STAR's Institute for Infocomm Research, who led the study. "To find a value, the hash table performs computations to quickly identify the indices and thus, its location. The challenges are that millions of values need to be stored, and the values are generated and transmitted extremely quickly."

A false colour micrograph shows microglia cells (green) infected by the Zika virus (blue). Researchers at the University of California San Diego School of Medicine, with colleagues in Brazil, report that the Zika virus is transmitted from mother to fetus by infected cells that, ironically, will later develop into the brain's first and primary form of defence against invasive pathogens. "It's a Trojan Horse strategy," said Alysson Muotri, PhD, professor in the UC San Diego School of Medicine departments of Pediatrics and Cellular and Molecular Medicine. "During embryogenesis -- the early stages of prenatal development -- cells called microglia form in the yolk sac and then disperse throughout the central nervous system (CNS) of the developing child. "In the brain, this microglia will become resident macrophages whose job is to constantly clear away plaques, damaged cells and infectious agents. Our findings show that the Zika virus can infect this e...

Single photons transmit quantum information between the network nodes, where they are stored in an atomic gas. Credit: University of Basel, Department of Physics Physicists from the University of Basel have developed a memory that can store photons. These quantum particles travel at the speed of light and are thus suitable for high-speed data transfer. The researchers were able to store them in an atomic vapor and read them out again later without altering their quantum mechanical properties too much. This memory technology is simple and fast and it could find application in a future quantum Internet. The journal  Physical Review Letters  has published the results.

                           Highly-stable perovskite solar cells, developed by Professor Jin Young Kim's team. A recent study, affiliated with UNIST, has presented highly stable perovskite solar cells (PSCs), using edged-selectively fluorine (F) functionalized graphene nanoplatelets (EFGnPs). The advance is important as the cells are made out of fluorine, a low-cost alternative to gold.

Researchers at Caltech have developed a prototype miniature medical device that could ultimately be used in "smart pills" to diagnose and treat diseases. A key to the new technology -- and what makes it unique among other microscale medical devices -- is that its location can be precisely identified within the body, something that proved challenging before.
