A “weekend warrior” approach to physical activity — getting 150 minutes of moderate-to-vigorous physical activity over one to two days instead of throughout the week — improved health and lowered the risk of death, finds a new study in the Journal of the American Heart Association.

Researchers at the University of Oxford, University of Exeter, and the National University of Singapore Yong Loo Lin School of Medicine present a new, interactive study: 

When choosing an embryo for implantation during in vitro fertilization (IVF), would you consider its chances of developing a health condition? What about traits like creativity, intelligence, or physical fitness? Tinker Tots is an interactive research project designed to explore how people make these difficult choices. By taking part, you help researchers understand how different genetic possibilities influence decision-making—while also gaining insight into your own and other people’s values.

For decades, California has ranked second only to Hawaii in housing and rental costs, and the state has seven of the 10 most expensive metropolitan areas in the nation. A new report finds the cost of building multifamily housing in California is more than twice as high as it is in Texas, with much of the difference driven by long permitting timelines and higher local development fees.

Scientists should experiment with creative ways of communicating their work to inspire action to protect the natural world, researchers say.
