The radio frequency spectrum, the basis for wireless telecommunications, is a finite resource that needs to be managed to satisfy the demands posed by the growth in wireless internet access. Researchers have developed a novel communications architecture for future ultrafast wireless networks that promises to achieve data rates previously only possible with optical fiber.READ MORE
A new energy-efficient data routing algorithm developed by an international team could keep unmanned aerial vehicle swarms flying -- and helping -- longer, report an international team of researchers this month in the journal Chaos, from AIP Publishing.
A new MIT-developed technique enables robots to quickly identify objects hidden in a three-dimensional cloud of data, reminiscent of how some people can make sense of a densely patterned "Magic Eye" image if they observe it in just the right way.READ MORE
A new type of computer memory which could solve the digital technology energy crisis has been invented and patented by scientists from Lancaster University in the UK. The electronic memory device - described in research published in Scientific Reports - promises to transform daily life with its ultra-low energy consumption.
A new wearable technology, an e-tattoo made from stretchy, lightweight material could make heart health monitoring easier and more accurate than existing electrocardiograph machines -- a technology that has changed little in almost a century.READ MORE
Can't stop checking your phone, even when you're not expecting any important messages? Blame your brain. A new study by researchers at UC Berkeley's Haas School of Business has found that information acts on the brain's dopamine-producing reward system in the same way as money or food.
Speculative memory side-channel attacks are security vulnerabilities in computers for which no efficient solutions have been found. The first such security threats, Meltdown and Spectre, were announced last year, but many more have been discovered since. Now, researchers have come up with a new security solution.
Researchers have conducted the first analysis of Bitcoin power consumption based on empirical data. They found that the cryptocurrency's carbon emissions measure up to those of Kansas City--or a small nation. The study suggests that cryptocurrencies contribute to global carbon emissions, an issue that must be considered in climate change mitigation efforts.READ MORE
As electronics become smaller and faster, the adoption of "wearables", like smart watches, has increased. However, like regular computers, wearables are vulnerable to conventional hacking. What if we could use the human body itself to transfer and collect information? This area of research is known as human body communication (HBC).
