    Tomatoes protect against development of UV-induced keratinocyte carcinoma via metabolomic alterations. Scientific Reports, 2017; 7 (1) DOI: 10.1038/s41598-017-05568-7

    Tomatoes protect against development of UV-induced keratinocyte carcinoma via metabolomic alterations. Scientific Reports, 2017; 7 (1) DOI: 10.1038/s41598-017-05568-7

    Discovery builds on previous evidence of cancer-prevention benefits. The new study found that male mice fed a diet of 10% tomato powder daily for 35 weeks, then exposed to UV light experienced, on average, a 50% decrease in skin cancer tumors compared to mice that ate no dehydrated tomato. The theory behind the relationship between tomatoes and cancer is that dietary carotenoids, the pigmenting compounds that give tomatoes their color, may protect skin against UV light damage.

    There were no significant differences in tumor number for the female mice in the study...

    Smart Atomic Cloud Solves Heisenberg’s observation problem

The optomechanical part of the hybrid experiment. The cryostat seen in the middle houses the vibrating membrane whose quantum motion is measured. Photo: Ola J. Joensen 3, If laser light used to measure motion of a vibrating membrane (left) is first transmitted through an atom cloud (center) the measurement sensitivity can be better than standard quantum limits envisioned by Bohr and Heisenberg.

    Researchers suggest you could operate a quantum computer in the cloud without revealing your data or the program you’re running. Here’s the scenario: you have sensitive data and a problem that only a quantum computer can solve. You have no quantum devices yourself. You could buy time on a quantum computer, but you don’t want to give away your secrets. What can you do? Writing in Physical Review X on 11 July, researchers in Singapore and Australia propose a way you could use a quantum computer securely, even over the internet. The technique could hide both your data and program from the computer itself...
