Among the many factors that impact digital marketing and online advertising strategy, a new study in the INFORMS journal Marketing Science provides insight to a growing trend among firms and big brands ... weather-based advertising. According to the study, certain weather conditions are more amenable for consumer responses to mobile marketing efforts, while the tone of your ad content can either help or hurt such response depending on the current local weather.

MIT researchers have developed a model that predicts a single heart cell's response to dwindling supplies of oxygen. Specifically, it evaluates a cell's ability to keep producing ATP -- a cell's primary fuel source -- and stay alive, even as it is increasingly deprived of oxygen.

Instead of having more children, a grandmother may pass on her genes more successfully by using her cognitive abilities to directly or indirectly aid her existing children and grandchildren. Such an advantage could have driven the evolution of menopause in humans, according to new research published in PLOS Computational Biology.

Robotics researchers have found a way for autonomous underwater vehicles to navigate strong currents with greater energy efficiency, which means the AUVs can gather data longer and better.

Of the women who carry the mutated BRCA1/2 genes, 45-65 percent will develop breast cancer, and 15-39 percent will develop ovarian cancer. Many women elect to undergo preventive surgeries that can significantly increase life expectancy, but can impact later fertility. However, few guidelines exist on the optimal age to undergo these procedures, and in what sequence. A new study in the INFORMS journal Decision Analysis provides insight to help physicians and patients make better-informed choices.

A research team led by New York University professor Maurizio Porfiri put forth a robotics-based study to control information flow in predator-prey interactions, as well as test the validity of transfer entropy when attempting to understand causal influences of the system. They report their findings this week in the journal Chaos, from AIP Publishing.

Method for modeling neural networks' power consumption could help make the systems portable.
