To produce the artificial bone segments, ACR has adapted a rapid prototyping machine, a device engineers use to quickly make models by building up layer upon layer of material.
The idea is to scan a damaged bone, using either computer aided tomography or magnetic resonance imaging, and generate a 3D computer model of the missing section. This would then be fed into ACR's machine, which can create more precise shapes than most prototypers. This approach is already occasionally used by surgeons, but not to replace load-bearing bones.
A missing bone segment could be created on the spot in the operating theatre, says Tony Mulligan, head of ACR. "Big segments would only take about an hour-and-a-half," he says, a fraction of the time it takes to build up a gap segment. The sections should be strong enough to bear weight without any need for a pin. And within about 18 months, the polymer section would be completely replaced by living bone.

INT. WELL-LIT, NON-NOIR WHITE ROOM
KEANU enters a white room, the walls of which are covered in monitors. A chair spins around to reveal THE EXPLAINER.
Cape Wind Associates hopes to build America's first offshore wind farm: 130 windmills, spaced a third to a half of a mile apart, across a shoal seven miles off the coast of Hyannis. Embedded in the ocean floor, each turbine would tower higher than the top of the Statue of Liberty's torch, its three 161-foot blades churning at 16 RPM. The wind forest promises to provide Cape Codders, on average, with 75% of their electricity, 1.8% of the total electrical needs of New England. [...]
Soon, the Alliance to Protect Nantucket Sound was filing lawsuits, mounting political pressure in Boston and Washington and, to bolster its legal case and maximize public anxiety, generating volumes of doomsaying critiques: [...] The yacht-club set opened its checkbooks, donating money and stock to cover the $100,000-a-month bills for rent, three full-time salaries, television and radio time, two lobbyists and three law firms. [...]
"Traditionally, power plants were built in poor neighborhoods, so people living in nice neighborhoods weren't forced to confront the human cost of using electricity," said Greg Watson of the Massachusetts Technology Collaborative, an agency that administers Massachusetts's renewable energy trust. "But unlike coal, oil or natural gas, which you can truck, pipe or barge, Mother Nature dictates where you can locate a wind farm."
LONDON (Reuters) - U.S. pop star Britney Spears is to get a pair of inflatable, throbbing breasts that will pulsate in time to her
dancing --at least her waxwork model will at Madame Tussauds museum in London.
"There are plans to make a new figure of Britney Spears," a spokeswoman said Friday. "She'll be very sexy and she'll have heaving bosoms. But this is only in the very early stages of planning." She said the model would be based on one of Britney's videos, in which she dances breathlessly around a pole, and would be accompanied by professionals who would teach museum visitors the tricks of the trade.
The initiative is the latest by the museum to make its models not just visual but tactile. "Brad Pitt has got a squeezable (latex) bum, but Britney would be the first with heaving bosoms," added the spokeswoman.
(Rumor has it that Jesus Christ Vampire Hunter is playing there saturday night and monday afternoon, but I can find no substantiating documentation of this. Apparently it's part of their bi-weekly Lesbian Jewish Amputee Film Festival or something.)
We are so not in the future yet.
