Sometimes, it takes worm glue to fix the hole in a heart. Inspired by creepy crawly creatures like the slug and the sandcastle worm, a team of scientists has created a surgical adhesive that could safely seal up the hearts of babies born with congenital heart defects. The bioinspired glue, described in Science Translational Medicine, could replace damaging staples, weak or toxic glues and reduce the need for repeated surgeries, said study coauthor Jeffrey Karp, a bioengineer at Brigham and Women's Hospital in Boston.

Dollar Tree Stores Inc. is recalling about 253,000 Chinese-made glue guns because they can short-circuit, causing them to smoke and catch fire. The Consumer Product Safety Commission said Dollar Tree was aware of seven incidents in which the glue guns short-circuited, including two injuries involving electrical shock and burns. The Crafters Square hot melt mini-glue guns were sold at Dollar Tree, Dollar Bill$, Dollar Express, Greenbacks, Only One $1, and Deal$ stores from February through August 2007, the commission said.

A new type of dry glue designed to mimic gecko feet is 10 times stickier than the gravity-defying lizards and three times stickier than similar glues, U.S. researchers said Thursday. A 1-inch square can support a 220-pound man climbing up a vertical surface, but it can be easily lifted and reapplied, the researchers reported in the journal Science. Like other gecko-inspired glues, the new glue uses a carpet of carbon nanotubes, thin filaments of carbon molecules. But attached to the ends of these filaments are curly strands of carbon that expand the surface area of the glue's gripping action.

The Food and Drug Administration approved a Super Glue-like substance Thursday for doctors to use in place of stitches on skin-deep wounds. Closure Medical Corp.'s DermaBond contains a variation of the chemical used in Super Glue. It quickly covers a wound with a flexible film that gradually wears off as new skin cells grow beneath it. DermaBond takes half as much time to apply as sutures and, because it's less painful, doesn't require a local anesthetic, said Closure, based in Raleigh, N.C.

For all the talk these days of porous borders and external threats to the United States, the core of our sense of security and identity as a nation has always come from within. What's surprising, perhaps, is that it derives less from our vaunted democracy or our freedoms than it does from that rather nebulous notion we call the American dream. The dream is the glue that keeps us all together. It's the vague promise that our lot will get better over time that gives us the patience to endure whatever indignities we suffer at the moment.

A new glue made of human blood by-products could replace stitches and surgical staples in some delicate operations and be used like a caulking agent on leaky blood vessels, University of Pennsylvania researchers say. Dr. Robert Weisman said he and colleagues have worked on developing such a glue for seven years. The substance is made from clotting agents derived from the patient's own blood. "There are operations where it's just too difficult to use sutures or wires," he said.
