Galaxy Zoo: Hubble ETH - IDSC - Flying Machine Arena The Flying Machine Arena (FMA) is a portable space devoted to autonomous flight. Measuring up to 10 x 10 x 10 meters, it consists of a high-precision motion capture system, a wireless communication network, and custom software executing sophisticated algorithms for estimation and control. The motion capture system can locate multiple objects in the space at rates exceeding 200 frames per second. While this may seem extremely fast, the objects in the space can move at speeds in excess of 10 m/s, resulting in displacements of over 5 cm between successive snapshots. The system uses this knowledge to determine what commands the vehicles should execute next to achieve their desired behavior, such as performing high-speed flips, balancing objects, building structures, or engaging in a game of paddle-ball. Although various objects can fly in the FMA, the machine of choice is the quadrocopter due to its agility, its mechanical simplicity and robustness, and its ability to hover.

The Higgs boson made simple STUTTGART, Germany — At the Mercedes-Benz headquarters here, a showroom display illustrates the rapid evolution of the iconic luxury brand’s hydrogen-fueled cars. In a 1992 prototype, the fuel cell takes up the entire cargo area of a delivery van. Across the room, today's model — now merely the size of an average television set — is displayed in front of a neon-lit outline of a compact passenger car. This “zero emission” engine, it appears, is ready for prime time. With the aid of government spending and joint efforts by Ford and Nissan, Daimler — Mercedes’s parent corporation — aims to start selling hydrogen-fueled cars to the public as early as 2017. If they take off, the biggest impact may be felt not in the car industry but in wind energy. To meet Europe's aggressive targets for emissions reductions, Daimler is developing hybrids and electric cars, too. “We’re very sure we can achieve a product cost level which is competitive [with today's hybrid cars]," he says.

Hot but Habitable? A new superterran exoplanet (aka Super-Earth) was found in the stellar habitable zone of the red dwarf star Gliese 163 by the European HARPS team. The planet, Gliese 163c, has a minimum mass of 6.9 Earth masses and takes nearly 26 days to orbit its star. Superterrans are those exoplanets between two and ten Earth masses, which are more likely composed of rock and water. Gliese 163 is a nearby red dwarf star 50 light years away in the Dorado constellation. Gliese 163c could have a size between 1.8 to 2.4 Earth radii, depending if it is composed mostly of rock or water, respectively. The detection of potential habitable exoplanets is pacing up. Scientists are trying to construct better ground and space observatories in the next decades to be able to detect smaller worlds, those more resembling Earth. The potential for habitable planets around red dwarf stars has been and issue of much debate.

Bell Labs Researchers at Bell Labs – Alcatel-Lucent’s research organization – collaborate closely with the company’s customers and product development teams to create the technologies that are transforming the way people connect with each other and with the information around them. What would our children want from 5G? What would our children want in THE communications platform of the future? It is likely a seamless network that adapts to them, rather than forcing them to adapt to the network.. Join the conversation about 5G > Bell Labs shows primacy at ECOC 2013 At the European Conference and Exhibition on Optical Communications, Bell Labs researchers presented post-deadline papers documenting major advancements in optical research. Learn about the future of optical networking > Who we are Our industry is subject to extraordinary forces of change. Our experts – many of them global leaders in their respective disciplines – collaborate to conduct fundamental and applied research.
