News this summer of a flu vaccine patch sparked a lot of chatter. Could getting vaccinated be as easy as putting on a bandage? Could there be fewer, or at least smaller, needles in our future?

Some companies and academic labs are working to make those things happen.

They're refining technologies that involve tiny needles, less than a millimeter long, and needle-free injectors that can send a dose of vaccine through your skin in a fraction of a second.

Some of these technologies are already available on the market, while others are still being tested.

Congress will consider imposing new sanctions on Russia and Iran as well as North Korea, after Republicans and Democrats agreed to changes that will allow the legislation to move ahead. The bill also aims to prevent President Trump from relaxing sanctions without lawmakers' consent.

Poland is poised to dissolve a key separation of government powers, as President Andrzej Duda is expected to sign a bill that puts the nation's Supreme Court under the control of the ruling party, despite citizens' protests and pleas from allies in the EU and U.S.

Aaron Albaugh peers out from under the brim of his cowboy hat, surveying the acres of hay fields in front of him. The fourth-generation rancher is raising about 450 cattle this year, in this remote corner of Lassen County, California.

His closest neighbor lives a half mile away. "And that's my brother," Albaugh says.

"If I want to go see a movie, it's 70 miles, round-trip," he adds. "If I want to go bowling, that's 100 miles, round-trip."

This week, the First Global Challenge, a highly anticipated robotics competition for 15- to 18-year-olds from 157 countries, ended the way it began — with controversy.

On Wednesday, members of the team from the violence-torn east African country of Burundi went missing. And well before the competition even began, the teams from Gambia and Afghanistan made headlines after the U.S. State Department denied the members visas. Eventually, they were allowed to compete.

The drama marred an otherwise upbeat event focused on kids and robots.

Walk up the white steps of the front porch where Mary Jo and Mike Picklo live, and you'll see three rocking chairs and a pair of binoculars.

The couple bought their home on five acres in 2003 and planned to spend their golden years overlooking a vista of green farmland and thick trees in western Pennsylvania.
