http://tjeld.uib.no/ The Oystercatcher is one out of very few shorebirds that actually feed their young. This is also a condition for successful breeding on roofs up to 30 meters above the ground. In Bergen the adults feed in the parks near the building where they breed, and bring the food for their young. It seems that they mainly deliver Earth-worms Lumbricidae sp. to the chicks. The chicks stay on the roof until they are more or less able to fly.Also http://en.wikipedia.org/wiki/Haematopodidae

PhysOrg: The Hubble Space Telescope has been with us for nearly two decades. In that time, its breathtaking images have captured people’s imaginations and its groundbreaking science has revealed some of the many secrets of our universe. This morning, at precisely 8:57 a.m. ET, a carefully orchestrated maneuver was carried out 350 miles above the Atlantic coastline of Africa, marking the successful end of the fifth and final shuttle servicing mission. [...] Thanks to new gyros, new batteries, new thermal blanketing and new science instruments, Hubble is poised to peer deeper into the cosmos than ever before. Spectacular images and data should start flowing from Hubble in about three months, after controllers have checked out and calibrated each of the observatory’s instruments and systems.

The three pink- and blue-colored parallelograms are the same. All blue lines are equal in length; all pink lines are also equal. Box B is simply Box C rotated counterclockwise. But the three parallelograms look different, and boxes B and C look different. Our visual system assumes that the diagonals in A and C are foreshortened and “stretches” them perceptually. The pink lines in B should be foreshortened and stretched, just as they are in C. But our visual system doesn’t stretch a horizontal quite as much as it stretches a diagonal.Most of the illusions (including the number 1) are animated on the site. Also check out the finalists of previous years in the menu on the left.

Planck is a space observatory designed to observe the anisotropies of the cosmic microwave background (CMB) over the entire sky, using high sensitivity and angular resolution. Mass: 1900 kg Orbit: Lissajous orbit about the second Lagrange point of the Earth-Sun system (L2), with an average amplitude of about 400 000 km. Objectives:
- High resolution detections of both the total intensity and polarization of the primordial CMB anisotropies;
- Creation of a catalogue of galaxy clusters through the Sunyaev-Zel'dovich effect;
- Observations of the gravitational lensing of the CMB, as well as the Integrated Sachs-Wolfe effect;
- Observations of bright extragalactic radio (Active Galactic Nuclei) and infrared (dusty galaxy) sources;
- Observations of the Milky Way, including the local interstellar medium, distributed synchrotron emission and measurements of the Galactic magnetic field;
- Studies of the local Solar System, including planets, asteroids, comets and the Zodiacal light.
The Herschel Space Observatory is a European Space Agency (ESA) mission originally proposed in 1982 by a consortium of European scientists Mass: 3400 kg Orbit: Lissajous orbit about the second Lagrange point of the Earth-Sun system (L2). Objectives: Herschel will specialise in collecting light from objects in our Solar System as well as the Milky Way and even extragalactic objects billions of light-years away, such as newborn galaxies, and is charged with four primary areas of investigation:
- Galaxy formation in the early universe and the evolution of galaxies;
- Star formation and its interaction with the interstellar medium;
- Chemical composition of atmospheres and surfaces of Solar System bodies, including planets, comets and moons;
- Molecular chemistry across the universe.

From Flickr description (with more video): Assembled in Quicktime from 2000 still images taken by using a Nikon D700 in the "interval timer" mode. The camera was fastened to an outside rail and set to take a photo every six seconds. Quicktime then assembled the photos into a .mov file that plays back at 12 frames per second. So, one minute of movie time represents 72 minutes of trip time on the channel. The first half begins just below the Port of Houston Authority Turning Basin (the very end of the channel) and continues down to Green's Bayou. The second half takes us from there to Morgan's Point at the head of Galveston Bay. From there we still have 31.5 miles of channel across the bay to the pilot station outside the Galveston jetties. It looks incredibly fast, but we were actually only making 5-6 knots in the first half and no more than 10 knots in the open areas of the second half.

The 27-year-old Zhao Liang is 2.46 meters tall -- 10 centimeters taller than Bao Xishun, who is recognized by the Guinness World Records as the world's tallest man. However, Zhao has not been independently measured by the Guinness judges.
Zhao's surgeon, Liu Yuchen with the Tianjin Anjie Hospital, said the Zhao will be able to walk normally two months after the surgery, but advised against participation in basketball exercises.
Zhao received a health checkup in the hospital before the surgery. Doctors measured his height under the media observation.
The doctor Liu said Zhao is in good health. He does not have any health complications related to his height.
More pictures... The tallest man who ever lived was Robert Wadlow at 272 cm.
