File-This Nov. 14, 2019, file photo shows students being escorted out of Saugus High School after reports of a shooting in Santa Clarita, Calif. For a few hundred dollars, tools and some elbow grease, you can make your very own rifle or handgun. It’s all perfectly legal and it can be done without leaving anything behind for the government to trace. These so-called “ghost guns” have long been popular among hobbyists or gun enthusiasts. But gun-control advocates say they are increasingly popping up in crimes, used by people who are prohibited from buying a firearm and are trying to circumvent a background check. Authorities said the teenager who fatally shot two classmates and wounded three others before saving the last bullet to kill himself, used a homemade handgun.(AP Photo/Marcio Jose Sanchez, File)

Vape debate: Are e-cigarettes wiping out teen smoking?

Study: Yellowstone bison mow, fertilize their own grass
FILE - In this Aug. 3, 2016 file photo, a herd of bison grazes in the Lamar Valley of Yellowstone National Park in Wyo.

This allows allowing them to feed in one area for two to three months during the spring and summer. Researchers say they found that large numbers of bison grazing in one area stimulates the growth of nutritious grasses and keeps the area greener longer. (AP Photo/Matthew Brown, File)
