If you are taking vitamin supplements to reduce your risk of heart disease or cancer, a government panel of health experts wants you to know that you're probably wasting your money. In some cases, those vitamins may actually increase your risk of cancer. The U.S. Preventive Services Task Force came to this conclusion Monday after reviewing dozens of studies, including many randomized clinical trials, considered the gold standard for medical research. The task force's final recommendation was published online Monday in the Annals of Internal Medicine.

The manipulation of human genes could lead to profound advances in our ability to cure or prevent terrible diseases. But in some cases, it might also mean introducing genetic material that could be passed from one generation to the next, changing the human gene pool in a manner that could inadvertently harm peoples' health. Such "inheritable" DNA is a hotly debated issue among bioethicists, and one that an advisory committee of the Food and Drug Administration will review Tuesday and Wednesday as it considers whether human trials should be allowed for a new therapy that could prevent a rare but devastating inherited disorder.

The Metrolink passenger railroad Thursday will become the first commuter service in the nation to roll out a sophisticated collision avoidance system designed to overcome human error. Had so-called positive train control been in place five years ago, experts say, it would have prevented Metrolink's deadly Chatsworth crash. In that accident, an engineer missed a red stop signal while text-messaging on his cellphone and struck a Union Pacific freight train head-on. Twenty-five people died and 135 were injured.

SACRAMENTO - Personal information collected from credit card shoppers would be better protected by upgrading the country's entire payment system to technology that has dramatically reduced fraud in Europe. That was the consensus of a group of retailers, bankers, credit card companies and consumer advocates at a legislative hearing Tuesday. Legislators delved into the causes of a recent hacking of about 70 million computerized customer records at Target Corp. and a smaller incident involving about 1.1 million customers at Neiman Marcus department stores.

SAN DIEGO - Kris Warren, a Marine veteran with combat duty in Iraq, remembers the disorientation and other problems that kept him from reentering civilian life. Finally he mustered the courage to ask for help from the Department of Veterans Affairs in Los Angeles. With that help over months, he was able to reunite with his wife and children and avoid slipping into homelessness. Now, Warren, 36, is part of an innovative VA program set to begin in San Diego: a residential treatment facility exclusively for Iraq and Afghanistan veterans in danger of becoming homeless.

The Culver City Ice Arena, which closed earlier this month after losing its lease, might reopen after the rock-climbing company that had planned to take over the space revealed last week that it would not. But City Manager John Nachbar said the city and the rink employees would first have to resolve many issues, including whether the facility's refrigeration system was safe. The unexpected news of Planet Granite's lease cancellation was a relief to the Takahashi family, longtime employees of the rink who hope to operate it for at least six months.

The Department of Transportation will push the development of a short-range radio system aimed at stopping crashes by allowing cars to exchange basic facts about speed and direction to other vehicles as fast at 10 times a second. Called vehicle-to-vehicle communications, such a system would give vehicles the ability to warn drivers of potential dangers as far as 300 yards away. The technology could be linked to safety systems already in some vehicles that automatically trigger the brakes or make steering adjustments to stop collisions. “This is just the beginning of a revolution in roadway safety,” U.S. Transportation Secretary Anthony Foxx said Monday.

MOSCOW - President Vladimir Putin said Russian authorities will "do our best" to prevent terrorist attacks at the Sochi Winter Olympics, which will take place in the shadow of an Islamist insurgency in the restive Caucasus region. "We have a perfect understanding of the scope of the threat and how to deal with it and how to prevent it," Putin said in an interview broadcast Sunday. "I hope that our law enforcement agencies will deal with it with honor and dignity, the way it was during other major sports and political events.

WASHINGTON - The deadly 2012 assault on the U.S. diplomatic compound in Benghazi, Libya, was caused by the failure of the State Department to adequately protect the facility and poor intelligence-gathering by the CIA and other agencies, according to a harsh assessment by the Senate Intelligence Committee. The panel's findings, contained in a declassified 78-page report released Wednesday, criticize the State Department for failing to increase security at the isolated, undermanned compound.

WASHINGTON - Many of President Obama's closest advisors have embraced a controversial assessment of one of the National Security Agency's major data collection programs - the belief that the Sept. 11, 2001, terrorist attacks could have been prevented had government then possessed the sort of vast trove of Americans' telephone records it holds now. Critics of the NSA program, and some scholars of America's deadliest terrorist attack, strenuously dispute the view that the collection of phone data would necessarily have made a difference or that the possibility justifies the program now. The presidential task force that reviewed surveillance operations concluded last month that the program "was not essential" to preventing terrorist attacks.
