“Zaha Hadid has completed a building for the American University of Beirut, which cantilevers out over a public courtyard and a series of elevated pathways.”The IFI's design builds upon the institute's mission as a catalyst and connector between AUB, researchers and the global community. Routes, views and links within the campus converge to define the IFI as a three-dimensional intersection; a space for university's students, fellows and visitors to meet, connect and engage with each other and the wider world.The building takes full advantage of the region's tradition and expertise of working with in-situ concrete. Passive design measures, high efficiency active systems and recycled water technologies minimize the building's impact on the local and wider environment.More at the link...

It’s never been easier to build a product, raise money, and start a company. But there’s a catch: fierce competition means that the life of a startup is often brutish and short. Why are so many people gambling on ventures that are likely to end badly?
"Students need a voice. By voice, I mean the ability to recognize their own beliefs, practice articulating them in a variety of forms, and then find the confidence — and the platform — to express them ...".

You open the overstuffed kitchen cabinet and a drinking glass tumbles out. With a ninjalike reflex, you snatch it before it shatters on the floor, as if the movement of the object were being tracked before the information even reached your brain. According to one idea of how the circuitry of the eye processes visual data, that is literally what happens. Now, a deep anatomical study of a mouse retina—carried out by 120,000 members of the public—is bringing scientists a step closer to confirming the hypothesis.Researchers have known for decades that the eye does much more than just detect light. The dense patch of neurons in the retina also processes basic features of a scene before sending the information to the brain. For example, in 1964, scientists showed that some neurons in the retina fire up only in response to motion. What's more, these “space-time” detectors have so-called direction selectivity, each one sensitive to objects moving in different directions. But exactly how that processing happens in the retina has remained a mystery.The stumbling block is a lack of fine-grained anatomical detail about how the neurons in the retina are wired up to each other. Although researchers have imaged the retina microscopically in ultrathin sections, no computer algorithm has been able to accurately trace out the borders of all the neurons to map the circuitry. At this point, only humans have good enough spatial reasoning to figure out what is part of a branching cell and what is just background noise in the images.Enter the EyeWire project, an online game that recruits volunteers to map out those cellular contours within a mouse’s retina. The game was created and launched in December 2012 by a team led by H. Sebastian Seung, a neuroscientist at the Massachusetts Institute of Technology in Cambridge. Players navigate their way through the retina one 4.5-micrometer tissue block at a time, coloring the branches of neurons along the way. Most of the effort gets done in massive online competitions between players vying to map out the most volume. (Watch a video of a player walking through a tissue block here.) By last week, the 120,000 EyeWire players had completed 2.3 million blocks. That may sound like a lot, but it is less than 2% of the retina.The sample is already enough to reveal new features, however. The EyeWire map shows two types of retinal cells with unprecedented resolution. The first, called starburst amacrine cells (SACs), have branches spread out in a flat, plate-shaped array perpendicular to the incoming light. The second, called bipolar cells (BPs), are smaller and bushy. The BPs come in two varieties, one of which reacts to light more slowly than the other—a time delay of about 50 milliseconds. The SACs and BPs are known to be related to direction sensitivity, but exactly how they sense direction remains to be discovered.

Although 75% of the planet is a relatively unchanging ocean of blue, the remaining 25% of Earth's surface is a dynamic green. Data from the NASA/NOAA Suomi NPP satellite is able to detect these subtle differences in greenness. The resources on this page highlight our ever-changing planet, using highly detailed vegetation index data from the satellite, developed by scientists at NOAA. The darkest green areas are the lushest in vegetation, while the pale colors are sparse in vegetation cover either due to snow, drought, rock, or urban areas. Satellite data from April 2012 to April 2013 was used to generate these animations and images.
