In California, parents could claim a personal belief exemption to vaccination, and the rate of kindergartners without up-to-date vaccinations was 9.84% in 2013. In 2016, due to measles outbreaks, California passed a bill banning all personal belief exemptions. The rate was halved to 4.87% in 2017.

Livestock are responsible for 14.5% of global greenhouse gas emissions, with the majority from beef and milk production because cattle emit so much methane. A new study has found that changing the cow’s microbiome could cut methane by 50%, through selective breeding, or using probiotics in calves.

The first complete wiring diagram of an animal's nervous system has been completed. The findings mark a major milestone in the field of "connectomics," the effort to map the myriad neural connections in a nervous system to find the specific nerve connections responsible for particular behaviors.

Researchers engineered a strain of non-pathogenic bacteria that colonize solid tumors and safely deliver immunotherapies, acting as a Trojan horse. The therapy led not only to complete tumor regression in a mouse model of lymphoma, but also significant control of distant, uninjected tumor lesions.

In survey of people who maintained 30 lbs of weight loss in a year, 68% worked out at the same time each day, 47.8% of whom worked out in the early morning. Timing was key to forming an exercise habit, but specific time of day is not as important as working out at the same time every day. (n=375)

Archaeologists find chemical traces of pine resin on 10 Neolithic stone tools, suggesting that Neanderthals were hafting their tools and securing them in place onto wooden handles with resin between 55,000 and 40,000 years ago—long before Homo sapiens set foot in Europe.
