Energy-harvesting design aims to turn Wi-Fi signals into usable power

April 12th, 2020 at 1:25 pm » Comments Off

Terahertz waves are pervasive in our daily lives, and if harnessed, their concentrated power could potentially serve as an alternate energy source. Imagine, for instance, a cellphone add-on that passively soaks up ambient T-rays and uses their energy to charge your phone. Any device that sends out a Wi-Fi signal also emits terahertz waves —electromagnetic […]



Scientists develop AI that can turn brain activity into text

April 12th, 2020 at 1:21 pm » Comments Off

Researchers in US tracked the neural data from people while they were speaking Reading minds has just come a step closer to reality: scientists have developed artificial intelligence that can turn brain activity into text. While the system currently works on neural patterns detected while someone is speaking aloud, experts say it could eventually aid […]



Cloud data speeds set to soar with aid of laser mini-magnets

March 15th, 2020 at 1:06 am » Comments Off

Model of a single-molecule magnet Tiny, laser-activated magnets could enable cloud computing systems to process data up to 100 times faster than current technologies, a study suggests. Chemists have studied a new magnetic material that could boost the storage capacity and processing speed of hard drives used in cloud-based servers. This could enable people using […]



Wi-Fi 6 will double your network’s range and triple its speed — once you upgrade your router, phone, PC, and everything else

January 17th, 2020 at 9:56 pm » Comments Off

Wi-Fi 6 will upgrade your workhorse wireless network 5G is great, but it’s a big Wi-Fi upgrade that’ll likely help you out sooner with faster speeds and longer range at home, school and work. We get it. 5G is a big deal. But honestly, you likely use Wi-Fi networks as much or more with your […]

Guangdong becomes focus as China races the US to build bigger particle accelerators Scientist says the competition between the two countries will ultimately be for the good of the human race. Scientists in southern China are planning to create machines that will be used to unravel the mysteries of the building blocks of the universe. […]



The next big leap in space travel will use hypersonic planes

October 18th, 2019 at 12:13 am » Comments Off

Scramjets capable of flying at Mach 15 will make it easier and cheaper to send spacecraft and people into orbit, says hypersonics expert Michael Smart. Sending satellites, spacecraft and humans into space is an expensive business. If humanity wants to venture further across the Solar System, we need ways of reducing the cost. Perhaps the […]

A breakthrough for A.I. technology: Passing an 8th-grade science test

September 16th, 2019 at 11:51 am » Comments Off

SAN FRANCISCO — Four years ago, more than 700 computer scientists competed in a contest to build artificial intelligence that could pass an eighth-grade science test. There was $80,000 in prize money on the line. They all flunked. Even the most sophisticated system couldn’t do better than 60 percent on the test. A.I. couldn’t match […]
