Physicists record “lifetime” of graphene qubits

This could provide stepping stone to practical quantum computing. Researchers from MIT and elsewhere have recorded, for the first time, the "temporal coherence" of a...

Scientists use ‘blacklist’ computing concept to streamline genetic analysis

Researchers at the Icahn School of Medicine at Mount Sinai and The Rockefeller University have discovered a new use for a long-standing computational concept...

5 things you need to know about fitness trackers

Most modern fitness trackers are electronic devices you wear on your wrist to track steps, overall physical activity, sedentary behavior and sleep. They typically work...

Living cells can help create better encryption keys

Living cells, regardless of the type, can be kept around for a long time and because they move constantly, can be photographed repeatedly to...

Special magnets make spin-based memory more efficient

A new magnetic device can manipulate digital information 20 times more efficiently and with 10 times more stability than commercial spintronic digital memories, say...

New way to hide images and information in plain sight

What is real is not always as it appears. UCF researchers have found a way to hide information on materials and only make it...

Clean up your cyber-hygiene – 6 changes to make in the new year

Data breaches, widespread malware attacks and microtargeted personalized advertising were lowlights of digital life in 2018. As technologies change, so does the advice security experts...

Scientists develop 128Mb STT-MRAM with world’s fastest write speed for embedded memory

Scientists have developed 128Mb-density STT-MRAM (spin-transfer torque magnetoresistive random access memory) with a write speed of 14 ns for use in embedded memory applications,...

Hybrid qubits solve key hurdle to quantum computing

Spin-based quantum computers have the potential to tackle difficult mathematical problems that cannot be solved using ordinary computers, but many problems remain in making...

Wake-up timer saves power for Internet of Things sensors

Researchers invented a low-cost ‘battery-less’ wake-up timer that cuts power consumption of IoT sensor nodes by 1,000 times, contributing to long-lasting operation. The wake-up...
