Timing and intensity of oral sex may affect risk of oropharyngeal cancer

Human papillomavirus (HPV) can infect the mouth and throat to cause cancers of the oropharynx. A new study published early online in CANCER, a peer-reviewed journal of the American Cancer Society, has found that having more than 10 prior oral sex partners was associated with a 4.3-times greater likelihood of having HPV-related oropharyngeal cancer. The […]

Cancer’s intelligence | EurekAlert! Science News

Dr. J. James Frost and The International Journal of Unconventional Computing will soon be publishing “Cancer’s Intelligence” which reports that Cancer can be analyzed as an intelligent system of collaborating and computing cells. The limitations of the current regime of cancer research and treatment are addressed, and the resultant need for new paradigmatic thinking is […]

Cooperation with R&D organizations is significantly distinctive for advanced innovators

The innovation performance of firms depends on their ability to innovate in cooperation with external partners. In a study, HSE researchers found that most of innovation in Russian manufacturing happens in a sort of open processes, but extensive cooperation networks are barely detectable. The study was published in the December issue of Foresight and STI […]

High achievement cultures may kill students’ interest in math — especially for girls

A new study in Frontiers in Psychology suggests that high national math achievement combined with societal pressures may contribute to how well girls and boys like math. Past research has shown that achievement-driven cultures frequently correlate with less enthusiasm for learning subjects like math. This study of over 500,000 eighth graders from 50 countries is […]
