Over the years, chemists have figured out how to make glues that stick to practically every material known to humans. Nowadays, that includes every material known to make up humans. One of the latest adhesives for use in the body, TissuGlu, aims to eliminate the need for fluid drains after reconstructive surgeries such as tummy tucks or mastectomies. The Pittsburgh developers already have gotten it approved in Europe. Another novel stickum may vastly improve surgeons' ability to repair congenital holes in newborns' hearts.

Three decades of the extremes of Philadelphia's winters and summers take their toll on a building - even one considered to be environmentally state-of-the-art when built. That's why construction workers have begun what will be a seven-month task of resealing the shiny, black glass panels that make up the distinctive exterior of Peco Energy Co.'s headquarters at 2301 Market St. Some passersby began to notice the work last week, especially after construction crews removed and began disposing of several large PVC-like pipe structures that decorated the plaza area around the building.

PennDot officials, still puzzled by a defective road sealant that caused hours-long backups for morning commuters last week in Montgomery County, have switched to a more reliable but pricier alternative. On Aug. 8, southbound traffic on Interstate 476, known as the Blue Route, was squeezed into one lane after the latex asphalt sealant failed to harden overnight on the other two southbound lanes. That, in turn, clogged traffic entering the Blue Route from the Pennsylvania Turnpike, creating backups as long as 17 miles.

A bad batch of blacktop on the Blue Route turned faces red at PennDot yesterday. Embarrassed officials apologized to drivers stuck in mammoth jams after a road sealant applied by overnight construction crews failed to harden in time for the morning rush hour. The goop forced southbound traffic on I-476, known as the Blue Route, to squeeze into one lane just south of the Schuylkill Expressway. Southbound traffic on the Pennsylvania Turnpike's Northeast Extension, in turn, backed up more than 10 miles to the Lansdale interchange.

Dean Johnson, host of the renovation TV program Hometime, crouched in the corner of a kitchen, showing John Channon how to install 12-by-12-inch ceramic tiles along blue chalk guidelines he carefully snapped along the fiber-cement underlayment known as Hardiboard. Before applying the adhesive, Johnson and Channon placed several tiles side by side on the floor along the chalk line, both to see how they would fit and to determine the spacing between them, so that the grout lines would be even.

Authorities evacuated about 700 students from Berlin Community School yesterday morning when fumes from paint sealant used on the roof made some children ill. Camden County officials said the fumes were reported more than an hour after they were first noticed in the school at 215 S. Franklin Ave. No one was seriously injured, but an emergency coordinator later criticized the school for waiting to call authorities. A teacher and students in an eighth-grade science classroom began complaining about the fumes about 9 a.m. Science teacher Barbara Rote and 37 students were taken to area hospitals, said George Hahn, the borough's emergency management coordinator.

WASHINGTON PESSIMISTS, THAT WE ARE, POLL SAYS When Americans think about their country's future, they think dour thoughts - and they almost always have, says a pollster analyzing years of readings of the American mind-set. Everett C. Ladd, executive director of the Roper Center for Public Opinion Research at Storrs, Conn., also finds that discontent is rampant in the world's richest economies. People in Great Britain, France, Japan, Germany, Spain, Italy and Canada, in a variety of polls taken by his organization and others since last fall, have said that their homelands' economic situations were bad and getting worse, he said.

For years, Dick Tobin kept looking for the tough stuff. He pounded surfaces with boards and a hammer. He soaked them in water. And finally, he and other city health officials decided they'd found it. They say they're ready to approve a cheaper and safer way to reduce lead paint hazards in some of Philadelphia's contaminated homes. Starting late this summer, city crews will begin spreading an epoxy-like coating over lead paint on many surfaces, instead of always removing the paint.

Q. What's the best way to install double-glass French doors? We have been told by one person that sealing on the inside is the best way, and another person told us that sealing on the outside is the best way. Which is correct? - H.K. A. They're both good methods, but the best way is to do both. The two-step process is simple. A metal flashing should be installed across the top of the opening at the exterior, and foam or caulk sealant should be used to completely fill the gap between the frame of the door and the frame of the opening in the wall.
