Temple University researchers have used state-of-the-art molecular scissors to cut out dormant HIV hiding in human cells, fueling hopes for curing - not just suppressing - the insidious infection that causes AIDS. The HIV removal experiment was conducted in cells in the lab, and the scissors did not work on every cell, so the approach is a long way from use in the clinic. Still, the study, published Monday in Proceedings of the National Academy of Sciences, shows how new genetic editing technologies could be harnessed to conquer the AIDS virus.

The AIDS community mourned the loss of one of its top researchers and advocates in the jet crash in Ukraine, a "humanist" whose life - and death - reminded some of the death of another leading AIDS scientist, from Philadelphia, in a plane crash 16 years ago. Six delegates to the 20th International AIDS Conference - down from initial reports of 100 - were confirmed to have been on the plane, shot down en route from Amsterdam to Kuala Lumpur, Malaysia....

Two new prostate cancer studies have found that many low-risk patients have been receiving more treatment than is needed or helpful - racking up millions of dollars in excess health-care costs and, potentially, causing more physical harm than good. One of the studies, both of which were published Monday in JAMA Internal Medicine, showed that among patients whose cancer was not aggressive, those who received hormone therapy as their primary treatment did not live any longer than those who were merely carefully monitored.

Albert J. Stunkard, 92, a renowned pioneer in the research and treatment of obesity and eating disorders, died Saturday at his home in Bryn Mawr. Dr. Stunkard died suddenly after recovering from a recent bout of pneumonia, said his wife, Margaret S. Maurin. A professor emeritus of psychiatry at the University of Pennsylvania's Perelman School of Medicine, Dr. Stunkard, known as Mickey, was a passionate and obsessive researcher. He worked at his office at Penn until he was 90, said his wife.

The surgeon delivered the bad news on Elizabeth Koniz's lumpectomy: "We didn't get clean margins. " Stunned, she couldn't think of anything else. "The words rang in my head," said Koniz, a 48-year-old admissions coordinator at Temple University School of Medicine. "I had terrible anxiety. I was nervous at medical appointments. I had tremendous trouble sleeping and cried for weeks after the diagnosis. " About a third of cancer patients experience high levels of anxiety - intense distress, although not typically to the level of post-traumatic stress disorder - after getting the diagnosis or during a difficult moment in treatment.

Melinda H. Keefe shared the world's horror when a painting by Mark Rothko, one of her favorite artists, was defaced with graffiti. Along with her initial shock at the vandalism came another emotion: a determination to do something about it. Keefe, a senior research scientist at the Dow Chemical Co., volunteered her expertise in researching what solvents might work best at removing the vandal's ink. More than a year and a half later, the successfully...

New Jersey sought an injunction Thursday to halt research off the coast that the state says "could adversely impact" marine life and the state's tourism and fishing industries. The complaint, filed in U.S. District Court in Trenton, seeks to prevent a National Science Foundation-owned research vessel from conducting studies that would involve aiming loud pulses of sound deep into the ocean floor. Special acoustic equipment would capture the reflected sound waves and convert them into images that would allow scientists to discern sea-level changes from as long ago as 50 million years.

David W. Taylor was eager to go bodysurfing with his son, Jonathan, but thought the waves at Cape May would be too tame for a good ride. Instead, he ended up getting a ride to the emergency room. Caught off-guard by a wave that hit him from behind that day in August 2007, the Lansdale resident suffered a broken neck - a type of injury that is all too familiar for physicians near New Jersey and Delaware beaches. In a single week in July 2012, for example, the AtlantiCare Regional Trauma Center in Atlantic City saw eight patients with spinal cord injuries sustained on the beach or in the water.

Edward J. Welch, 92, of Springfield, Delaware County, a research chemist for the DuPont Co. who helped develop a rugged coating for pots and pans, died Wednesday, June 11, of pneumonia at Riddle Memorial Hospital. Early in his career, Mr. Welch worked in the company's paints and coatings division, based at Marshall Laboratories in Philadelphia. It was while working in Wilmington for the new product division in 1976 that he helped create Teflon II, SilverStone, a three-coat fluoropolymer application that made for a more durable finish on cookware than the nonstick coating Teflon, according to a company history.

Score a big hit - and a tip of the yarmulke - for persistent sleuthing to Mary O'Connor Ward-Donegan, 87, of Ridley Park, the youngest sister of Cardinal John J. O'Connor, the dynamic former Catholic archbishop of New York. Ward-Donegan used the family-tree tracing service Ancestry.com - and her own dogged research - to unearth a fact even her now-deceased brother apparently never knew: Their mother was born Jewish. Hebraic law holds that any child born of a Jewish mother is a Jew. That means O'Connor, an influential prelate who for six years led the nation's second-largest archdiocese, could be considered one, too. "I think it might interest some people to look into their own roots.
