Glass may be hard, but it's all too easy to break, as anyone who's seen a shattered window knows. But now scientists have discovered that they can make glass 200 times tougher than normal by making it 'weaker' - using a laser to etch wavy micro-cracks into an otherwise solid surface. The discovery, described last month in Nature Communications, borrows secrets from mollusk shells, which use very brittle, breakable materials to create some of nature's toughest structures. Seashells lined with iridescent mother-of-pearl are more than just pretty - they're a remarkable feat of microengineering, said study co-author François Barthelat, a mechanical engineer at McGill University in Quebec, Canada.

The debut of the new $25-million Hollywood Bowl shell last season has opened a new chapter in the history of the landmark, retaining its iconic scalloped shape while incorporating a halo-like canopy into the design to improve acoustics. The new Bowl is the latest in a series of shells that date back to the early 1920s.

A tortoise's zookeepers in Cleveland are the ones feeling slow after discovering after more than 50 years that "Mary" is actually a male. Officials at the Cleveland Metroparks Zoo say it can be tough to establish the sex of a Aldabra giant tortoise because the reproductive organs normally aren't visible. But Mary's maleness was revealed this month during a routine exam. A spokesman says the zoo is renaming the tortoise Terry. When the reptile arrived at the zoo in 1955, it was assumed he was a she because of a flatter shell, shorter tail and smaller size than most males.

If you ever needed a reminder of how much good there is in the world - and these days, who doesn't? - just cook a Dungeness crab. It is so easy to prepare; the meat is so sweet and tender; it is so nearly perfect just as it comes in its original wrapper. Surely, some greater power must love us mightily to give us anything that delivers such pleasure and demands so little. Every year at the holidays my family has a ritual dinner of crab. We sit around and eat as much of it as we possibly can and tell the stories of our year.

Elvis has returned. As a Raider. Suspended defensive back-special teams captain Elvis Patterson, his career as a Raider and perhaps in the NFL in jeopardy, has been reinstated by the Raiders. The 31-year-old Patterson was suspended by Coach Art Shell on July 31 after Patterson got into a dispute with defensive backfield coach Jack Stanton. That argument ended when Patterson body-slammed the 54-year-old Stanton to the ground. The incident occurred in Flagstaff, Ariz.

Residents of a Morongo Valley neighborhood were startled Friday morning to find what appeared to be a Russian Scud missile on a truck parked on their street. California Highway Patrol officers determined that the missile, destined for an Air Force facility in Tonopah, Nev., was an inert shell used for training -- and not a threat.

Throughout history, there wasn't all that much to making a drum. Get a strong tubular shell. Stretch a skin over it. Hit it. The general principle hadn't changed much, even in modern times. Then William J. Bausch III had a dream. "I was building a drum shell out of stray pieces of wood," he recalled. In his dream, he cut wedges off the tops and bottoms of the wood, and used them to separate the vertical staves. Three years later, Bausch has a fledgling drum-making business and a 20-year patent for his so-called vertically vented drum shell design.

Lyndon B. Johnson was president, "My Fair Lady" swept the Oscars and Martin Luther King Jr. was leading marches across the South. The year 1965 was also when a 13-year-old boy in Pennsylvania found a box turtle, carved his initials and the year into its rock-hard shell, and then let the creature go. He forgot about it until this week when his father, who still lives on the property, found a box turtle meandering on his land, turned it over,...
