This 8ft tower of teeth is foul, and the summit of 15 years work by Yu Qian, a Chinese dentist who is trying to raise awareness about dental hygiene by word of mouth. Or, as it turns out, an awesome viral film gone global.
His piece of art is made from 28,000 human teeth (URGH). So far he has treated 100,000 patients, and ‘harvested’ 28,000 diseased teeth from his patients.
In an April study, neuroscientists led by Sasha Devore at the Massachusetts Institute of Technology tested the widely held hypothesis that specialized cells in the brain actively suppress neuronal response to echoes. Using electrodes in a cat’s midbrain, researchers measured cells’ responses to a sound and its reverberations. They found that the cells that sense a sound’s direction of origin responded more strongly to the first 50 milliseconds of sound waves than they did to the later waves—their activity simply tapered off after the onset of the sound. The tapering response, a much simpler mechanism than the earlier theory of suppression, allows the brain to easily tune in to original sounds and pinpoint who or what is making noise.
Ehrlich and Japanese student Sahachiro Hata produced their 606th preparation of an arsenobenzene compound in 1907. Ehrlich watched on Aug. 31 two years later, as Hata injected chemical No. 606 into a rabbit with syphilitic ulcers. The next day, no live spirochetes could be found on the animal’s ulcers, and within three weeks, the ulcers were completely gone.
After testing the drug on mice, guinea pigs and many more rabbits, Ehrlich and Hata sent their miracle cure to the chemical firm Hoechst, which marketed it under the name Salvarsan. The drug became an almost instant success around the world, although many criticized Ehrlich for creating a chemical that might encourage promiscuity.
Depressed people often think intensely about their problems. These thoughts are called ruminations; they are persistent and depressed people have difficulty thinking about anything else. Numerous studies have also shown that this thinking style is often highly analytical. They dwell on a complex problem, breaking it down into smaller components, which are considered one at a time.
This analytical style of thought, of course, can be very productive. Each component is not as difficult, so the problem becomes more tractable. Indeed, when you are faced with a difficult problem, such as a math problem, feeling depressed is often a useful response that may help you analyze and solve it. For instance, in some of our research, we have found evidence that people who get more depressed while they are working on complex problems in an intelligence test tend to score higher on the test.
The building itself is a complicated juxtaposition of different ideas and concepts. It forms a spiraling circle around a strong vertical core that allows visitors to the library to move between floors. The museum’s curves form a möbius strip, so the interior becomes the exterior and back again; likewise the walls become the roof and the roof transforms back into the walls. The interior corridors are naturally daylit through geometric openings in the exterior shell, creating beautifully lit spaces perfect for reading.
To minimize cooling loads on the library, BIG Architects employed some advanced computer modeling to calculate the thermal exposure on the building envelope. Because of the warping and twisting of the exterior, some parts of the building receive more light than others. By taking that information, BIG was able to create a geometric pattern or “ecological ornament” to regulate the solar impact.
