"The need for artificial joint replacements in people with osteoarthritis could soon be bypassed with injectable polymer implants that stimulate rebuilding of bone structures.
The research is being headed by Bristol University’s team of stem cell and tissue engineering experts in collaboration with researchers from Qatar and Canada. Speaking to The Engineer, lead investigator Dr Wael Kafienah of Bristol explained the rationale behind the project."

Search Engines for the Human Body
A Search Engine for the Human Body: Microsoft software recognizes organs and other structures in medical images, FRIDAY, MARCH 11, 2011, by TOM SIMONITE
"A new search tool developed by researchers at Microsoft indexes medical images of the human body, rather than the Web. On CT scans, it automatically finds organs and other structures, to help doctors navigate in and work with 3-D medical imagery.
CT scans use X-rays to capture many slices through the body that can be combined to create a 3-D representation. This is a powerful tool for diagnosis, but it's far from easy to navigate, says Antonio Criminisi, who leads a group at Microsoft Research Cambridge, U.K., that is attempting to change that. "It is very difficult even for someone very trained to get to the place they need to be to examine the source of a problem," he says."

150° anniversario dell'Unità d'Italia
Soffermàti sull’arida sponda,
Vòlti i guardi al varcato Ticino,
Tutti assorti nel novo destino,
Certi in cor dell’antica virtù,
Han giurato: Non fia che quest’onda
Scorra più tra due rive straniere;
Non fia loco ove sorgan barriere
Tra l’Italia e l’Italia, mai più!

Tra l’Italia e l’Italia, mai più!

Laser-scan system to have a virtual view of Stonehenge
"Experts at English Heritage are using laser scanning and high-resolution digital imaging to create a virtual rendering of Stonehenge that will show it in detail and hopefully reveal new features.
The survey will map the standing and fallen stones of Stonehenge, as well as the top of the horizontal lintels.
Despite the vast amount of archaeological activity and academic study into Stonehenge and its landscape over the centuries, relatively little is known about the lichen-covered surfaces."

Revelations of a golden age
"For roughly 700 years, many of the greatest scientists lived in the Islamic world. The Western narrative, however, has often neglected the contributions of major figures such as the chemist al-Jabir, the mathematician al-Khwarizmi and the medic al-Razi, preferring instead to jump directly from Aristotle, Euclid, Archimedes and Ptolemy to Copernicus and Galileo in reporting scientific development over the ages. Yet the fact is that between the eighth and 15th centuries AD, the scientists of the Islamic world developed original theories in mathematics, astronomy, physics, medicine and engineering – frequently with the help of works translated into Arabic from Greek, Sanskrit, Pahlavi and Syriac sources." by George Gheverghese Joseph, Revelations of a golden age - physicsworld.com

Bingham used the Raimondi's maps of Peru for exploring the country. In the book "Inca Land, Explorations in the Highlands of Peru", Bingham is telling "Raimondi's marvelous energy led him to penetrate to more out-of-the-way Peruvian villages than any one had ever done before or is likely to do again. He stopped at nothing in the way of natural obstacles."

Antonio Raimondi
"Antonio Raimondi (1826 – 1890) was a prominent Italian-born Peruvian geographer and scientist. Born in Milan, Raimondi emigrated to Peru, arriving on July 28, 1850 at the port of Callao. In 1851 he became a professor of natural history. ...Throughout his career, Raimondi displayed a passion for all things Peruvian. He undertook no less than 18 extensive journeys to all regions of the country, studying the nation's geography, geology, botany, zoology, ethnography, and archaeology. In 1875, he collected his findings in the massive tome El Perú, ...".
