A myth is emerging that we can develop low-yield nuclear weapons that will destroy hardened, deeply buried targets of military interest without contaminating the atmosphere with deadly radioactivity. Such weapons, delivered by bombers, must penetrate below the Earth's surface before detonating in order to create the maximum destructive ground shock. There are problems with this myth: Its validity is doubtful and its consequences are dangerous.

When music and movement are energetically fused, great things can happen. Such was the case Saturday night at Los Angeles Theatre Center, where the locally based company Jazzantiqua presented "Midtown Sunset," a jazz ballet suite celebrating the Harlem Renaissance. Inspired by the art of Romare Bearden and poetry of Langston Hughes, the previously seen work exudes a heartfelt and compelling honesty.

I am not satisfied with the level of coverage that our media provided in our recent city election. I believe that the media had a responsibility to reveal that there were candidates who were only self-serving and working for a manipulative vote. I believe that our citizens were the losers on April 8 when they voted for one councilperson and one councilperson only or, what is worse, failed to vote at all. Someone once said that the person who is successful in only one area of life is a failure.

Intense radiation therapy for three weeks after surgery for early breast cancer keeps the disease at bay just as well as lower doses for five weeks, a study found. More than 1,200 women were treated with either the accelerated three-week dose of radiation or the standard five-week therapy, then tracked for recurrences for up to 12 years. The cancer returned to the same breast a decade after treatment in 6.2% of those treated for three weeks and 6.7% of those getting standard therapy, according to the study presented this week at the annual meeting of the American Society for Therapeutic Radiology and Oncology in Boston.

Alcoholic beverages from several foreign countries are being tested for radioactive contamination from the Chernobyl nuclear accident, the government announced today. Samples of alcoholic beverages being imported from countries affected in some degree by the radiation accident will be purchased at retail over the next several years for testing, the Bureau of Alcohol, Tobacco and Firearms said. Bureau officials have divided the countries into three risk categories for testing.

From the '50s through the '70s, a number of fiercely idiosyncratic singers took Latin American popular music to new levels of sophistication. Artists such as Rolando Laserie, Tito Rodriguez and Jose Jose had vision and romanticism to spare. Watching Luis Miguel on Wednesday during his second of six evenings at the Gibson Amphitheatre, you could not help but think that the Mexican pop star wishes he was one of those crooners from the good old days.

UCLA professor Keisuke Iwamoto answered reader questions about the dangers of radiation exposure in a live Web chat Thursday. Iwamoto, a faculty member at UCLA's Division of Molecular and Cellular Oncology, studies radiation exposure and how it can lead to cancer. In his research, he also has analyzed donated tissue samples from Japanese atom bomb survivors. Here's the transcript of the chat (moderated by L.A. Times staff writer Jeannine Stein with help from reader engagement editor Martin Beck)

The Food and Drug Administration has decided to impose new safety controls on medical imaging devices and encourage development of more precise dosing standards in a bid to reduce unnecessary exposure of patients to diagnostic radiation. The agency also will promote a personal medical imaging history card that will enable patients to keep track of the number of images, and the amount of radiation, they receive over time, according to a medical imaging safety initiative unveiled Tuesday.

The sun does lots of cool stuff. We couldn't live on Earth without it. But the havoc it wreaks with our skin is not so hot. The culprit is ultraviolet, or UV, radiation, which can actually be very useful in fluorescent lighting and sterilizing medical equipment, or by stimulating our bodies to make vitamin D. But a little goes a long way, and overexposure to UV radiation is a major cause of skin cancer. (It's classified as a human carcinogen by the U.S. Department of Health and Human Services and the World Health Organization.)
