The theorists who first created the mathematics that describe the behavior of the recently announced "invisibility cloak" have revealed a new analysis that may extend the current cloak's powers, enabling it to hide even actively radiating objects like a flashlight or cell phone.

Allan Greenleaf, professor of mathematics at the University of Rochester, working with colleagues around the globe, has announced a mathematical theory that predicts some strange goings on inside the cloak—and that what happens inside is crucial to the cloak's effectiveness.

Pulickel Ajayan, the Henry Burlage Professor of Materials Science and Engineering, is being awarded the MRS Medal from the Materials Research Society and has been named by Scientific American magazine as a Research Leader within the 2006 "Scientific American 50" -- the magazine's prestigious annual list recognizing outstanding acts of leadership in science and technology.

"Professor Ajayan is a world-renowned expert in fabricating materials and devices based on his creative chemical and physical manipulation of carbon," said Acting Provost Robert Palazzo. "His research is unlocking information about how to direct the assembly of carbon at the atomic level, providing opportunities for the assembly of a cornucopia of carbon-based nanostructures.

ESA's Mars Express has obtained images of the Cydonia region, site of the famous 'Face on Mars.' The High Resolution Stereo Camera photos include some of the most spectacular views of the Red Planet ever.

After multiple attempts to image the Cydonia region from April 2004 until July 2006 were frustrated by altitude and atmospheric dust and haze, the High Resolution Stereo Camera (HRSC) on board Mars Express finally obtained, on 22 July, a series of images that show the famous 'face' on Mars in unprecedented detail.

The data were gathered during orbit 3253 over the Cydonia region, with a ground resolution of approximately 13.7 metres per pixel. Cydonia lies at approximately 40.75° North and 350.54° East.

When kids head back to school this fall, they might have some brand new planets to memorize.  

The International Astronomical Union, currently meeting in Prague, is expected to vote on the definition of a planet. The organization, which has named planets and moons since it was founded in 1919, is debating a plan to establish that our solar system has 12 planets. 

Plant geneticists at Rutgers may have solved one of the fundamental concerns about genetically engineered or modified (GM or GMO) crop agriculture: genes leaking into the environment.

In a recent paper published in the Proceedings of the National Academy of Science, Rutgers Professor Pal Maliga and research associate Zora Svab advocate an alternative and more secure means of introducing genetic material into a plant. In GM crops today, novel genes are inserted into a cell nucleus but can eventually wind up in pollen grains or seeds that make their way out into the environment.

These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show the Galle Crater, an impact crater located on the eastern rim of the Argyre Planitia impact basin on Mars.

The HRSC obtained these images during orbits 445, 2383, 2438, 2460 and 2493 with a ground resolution ranging between 10-20 metres per pixel, depending on location within the image strip.

The images show Crater Galle lying to the east of the Argyre Planitia impact basin and south west of the Wirtz and Helmholtz craters, at 51° South and 329° East.

The images of the 230 km diameter impact crater are mosaics created from five individual HRSC nadir and colour strips, each tens of kilometres wide.
