Quantum computing: when ignorance is wanted

Quantum technologies for computers open up new concepts of preserving the privacy of input and output data of a computation. Scientists from the University of Vienna, the Singapore University of Technology and Design and the Polytechnic University of Milan have shown that optical quantum systems are not only particularly suitable for some quantum computations, but can also effectively encrypt the associated input and output data. ....

Smartphone study points to new ways to measure food consumption

E-Mail
A team of researchers has devised a method using smartphones in order to measure food consumption an approach that also offers new ways to predict physical well-being.
We ve harnessed the expanding presence of mobile and smartphones around the globe to measure food consumption over time with precision and with the potential to capture seasonal shifts in diet and food consumption patterns, explains Andrew Reid Bell, an assistant professor in New York University s Department of Environmental Studies and an author of the paper, which appears in the journal
Environmental Research Letters.
Food consumption has traditionally been measured by questionnaires that require respondents to recall what they ate over the previous 24 hours, to keep detailed consumption records over a three-to-four-day period, or to indicate their typical consumption patterns over one-week to one-month periods. Because these methods ask for participants to report behaviors over extend ....

Researchers design more secure mobile contact tracing

E-Mail
For public health officials, contact tracing remains critical to managing the spread of the coronavirus particularly as it appears that variants of the virus could be more transmissible.
The need for widespread contact tracing at the start of the pandemic led tech giants Apple and Google to announce a plan to turn iOS and Android phones into mobile beacons that alert users who opt in of potential exposure to COVID-19. Health officials in some states have used the technology in their pandemic response efforts, as have other countries around the world, but researchers at the University of Notre Dame say contact tracing apps created by third-party developers could leave users vulnerable to a host of privacy and security issues. ....

A research team in Korea has developed a ceramic fuel cell that offers both stability and high performance while reducing the required amount of catalyst by a factor of 20. The application range for ceramic fuel cells, which have so far only been used for large-scale power generation due to the difficulties associated with frequent start-ups, can be expected to expand to new fields, such as electric vehicles, robots, and drones. ....

To provoke more interest and excitement for students and lecturers alike, a professor from Florida Atlantic University s College of Engineering and Computer Science is spicing up the study of complex differential mathematical equations using relevant history of algebra. In a paper published in the
Journal of Humanistic Mathematics, Isaac Elishakoff, Ph.D., provides a refreshing perspective and a special shout out to Stephen Colbert, comedian and host of CBS s The Late Show with Stephen Colbert. His motivation? Colbert previously referred to mathematical equations as the devil s sentences and an unnatural commingling of letters and numbers - with the worst being the quadratic equation - an infernal salad of numbe ....
