Farmers want to use drones to scope out problem spots in crops fields or check in on livestock.

A highly anticipated batch of federal laws governing the use of drones could change the regulatory landscape and lead to an explosion in drone use by farmers.
Farmers see drones as a way to get a birds-eye view of their fields to find problem patches with crops. That information can allow farmers to be more precise with fertilizers and pesticides and, ultimately, save them money. But getting them in the sky without running afoul of federal regulation is proving to be a challenge.
Commercial use of drones is still widely banned in the U.S., though some companies have secured exemptions. Other farmers have gone rogue, flying drones over their property without all the proper permissions, daring federal regulators to put a stop to it. But the new federal rules due out later this year are expected to usher in a new era of farm machinery.

The bat disease known as white-nose syndrome has been spreading fast, killing millions of animals. But for the first time, scientists are seeing hopeful signs that some bat colonies are recovering and new breakthroughs could help researchers develop better strategies for helping bats survive.

Humans have been growing hemp for centuries. Hemp-based foods have taken off recently. So have lotions and soaps that use hemp oil. Studies underway now are examining how different compounds in cannabis could be used as medicine. There’s hope its chemical compounds could hold keys to medical treatments for Parkinson’s disease and childhood epilepsy.
Scientists studying industrial hemp say the plant holds a tremendous amount of promise. But to unlock its potential there’s very basic scientific research to be done.
A ship full of marine scientists is floating over the deepest part of the world: the Pacific Ocean's Mariana Trench. They're sending down probes to study life in one of the most hostile environments on the planet.
This week the researchers are targeting the two deepest spots in the trench — the Sirena Deep and the Challenger Deep — which each extend down about 7 miles beneath the ocean's surface.
