• Coyotes are what they eat: Feeding pups soft food changes their bones and muscle structures, making it more difficult for them to chomp on harder stuff later in life. That bites.

• If you get bored this weekend (and have $8,000 to spare), fret not. You can always build and launch your very own satellite.

• Run DMC: Listening to music in which the tempo matches a runner’s stride increases athletes’ endurance by about 15 percent.

• Cow-dung toothpaste, a deer penis, and guinea pigs: just a few of the bizarre items travelers have been caught attempting to smuggle through JFK International Airport. No wonder it takes so long to go through customs.
