"The official switch takes place at 2 a.m. Sunday – though, once you twist your watch stem or push the button on digital timepieces, it'll be 3 a.m. The annual ritual, which ends the first Sunday in November, when we get the hour back, has its holdouts. Arizona, for one, does not make the shift – although if you're fastidious about changing your watch and you happen to be traveling through the Navajo and Hopi nations that take up the much of the state's northeast, you'll stay busy. The Navajo make the switch; the Hopi, surrounded by the Navajo, do not. Hawaii also forgoes the change. It occupies a latitude close enough to the equator that the hours of daylight it sees as the seasons change don't vary much. Globally, the use of "summer" time, as many countries call the change, shows a strong north-south divide. The vast majority of countries using it are in the northern hemisphere, while the vast majority of countries south of the equator don't change their clocks during the longer periods of daylight in the austral spring and summer."

Can sensitive coral reefs survive another human generation?
- Coral reefs may not be able to survive another human decade because of the environmental stress we have placed on them, says author David Wallace-Wells. He posits that without meaningful changes to policies, the trend of them dying out, even in light of recent advances, will continue.
- The World Wildlife Fund says that 60 percent of all vertebrate mammals have died since just 1970. On top of this, recent studies suggest that insect populations may have fallen by as much as 75 percent over the last few decades.
- If it were not for our oceans, the planet would probably be already several degrees warmer than it is today due to the emissions we've expelled into the atmosphere.
Research has shown that men today have less testosterone than they used to. What's happening?
- Several studies have confirmed that testosterone counts in men are lower than what they used to be just a few decades ago.
- While most men still have perfectly healthy testosterone levels, its reduction puts men at risk for many negative health outcomes.
- The cause of this drop in testosterone isn't entirely clear, but evidence suggests that it is a multifaceted result of modern, industrialized life.
Michael Dowling, Northwell Health's CEO, believes we're entering the age of smart medicine.
- The United States health care system has much room for improvement, and big tech may be laying the foundation for those improvements.
- Technological progress in medicine is coming from two fronts: medical technology and information technology.
- As information technology develops, patients will become active participants in their health care, and value-based care may become a reality.
