When Guys Lose Fights, Girls
Like female African cichlid fish, humans might also possess an overwhelming evolutionary imperative to find the toughest, most combat-ready mates.
If the chosen male of a female African cichlid fish gets into a fight with another male, a more ancient part of the brain fires up, sending strong signals of anxiety to the rest of the brain. In the fish, this newfound concern is generally enough to make the female find a new mate, and a more subtle form of this may well go on in human brains as well. Researcher Julie Desjardins explains: "It is the same as if a woman were dating a boxer and saw her potential mate get the crap beat out of him really badly. She may not consciously say to herself, 'Oh, I'm not attracted to this guy anymore because he's a loser,' but her feelings might change anyhow."

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.
