Secret Service lapse

The alarm system protecting former President George H. W. Bush's Houston home did not work properly for more than a year starting in September 2013, according to a Department of Homeland Security Office of Inspector General report to be released today. CBS News White House correspondent Bill Plante says the report, which is partially redacted, also raises concerns about security at other former presidents' residences.

Weapons aimed

During a closed door briefing, officials from the Secret Service and Capitol Police revealed that multiple agencies had tracked the aircraft piloted by postman Doug Hughes, saying "multiple weapons" were trained the gyrocopter flying in restricted airspace over Washington, D.C., but security officials made a judgment call not to shoot it down, partly out of concern for the safety of people on the ground.

Wireless entry cars

Thieves are finding new ways around technology designed to keep them out of cars. While your key fob may be safely in your house, your locked car could actually be wide open for tech-savvy crooks. CBS News correspondent Vladimir Duthiers reports on how high-tech car thieves are exploiting security gaps.

Earlier concerns

CBS News has learned that a 2009 investigation by the Tulsa Sheriff's Office concluded that there were concerns over Robert Bates' behavior in the field. CBS News correspondent Omar Villafranca reports Bates, a 73-year-old reserve deputy, pleaded not guilty to second-degree manslaughter charges in the death of Eric Harris. Bates says he shot and killed Harris by mistake after pulling his gun instead of his taser.

British comedian fights ISIS

As the number of ISIS runaways increase, police are using a new weapon to try to keep people from joining the extremists: humor. Competing with the apparent excitement and even perceived glamour of the Islamic militant groups, people have learned how to tap into the cultures that recruit young western Muslims. CBS News correspondent Mark Phillips reports on a popular 29-year-old British comedian named Humza Arshad.

Democratic wedge

A looming trade deal between the U.S. and countries in the Asia-Pacific region is putting divisions in the Democratic Party on full display and could even become a wedge issue in the party's 2016 primary.

As crows fly

More than 30 million crows fly around the country, but they may be among the least understood of all creatures. CBS News correspondent Ben Tracy reports on new research into their soaring intelligence and surprising warmth.

Dog flu

An outbreak of canine flu has sickened more than 1,000 dogs in the Midwest, killing a handful and stirring concern among animal lovers nationwide that the highly contagious virus could strike their pets. Veterinarians believe it is very likely to spread to other parts of the country. What can be done?

How long?

More than five years after a final shuttle servicing mission -- and a quarter of a century since its launch in April 1990 -- the Hubble Space Telescope is operating in near flawless fashion, and engineers are optimistic the observatory will remain on the forefront of astronomy. But for how long?

Not enough

If you're hitting the gym every day but don't see the numbers going down on the scale, you might be going about weight loss all wrong. New research says focusing solely on exercise is not the answer to losing weight.

Success keys

When measuring job satisfaction and earnings, meaningful college experiences such as studying abroad, undergraduate research and internships don't appear to matter as much as students' majors and the schools they attend. This is a key conclusion of a study that questions conventional wisdom about the college activities that matter after students graduate and start their careers.

Younger self

Alice Barker, 102, has become the latest YouTube sensation. Barker was a Harlem Renaissance dancer in the 1930s and 1940s. She says she performed with some of the biggest stars in showbiz: Sinatra, Gene Kelley, Bojangles Robinson. But she had never seen herself on film. That all changed when volunteers at a nursing home found a vintage video of Barker and showed it to her for the first time. See her reaction.
