Working at the Armagh Observatory with Dr Simon Jeffery and Dr Tolis Christou, Nuffield Science Bursary scholar Elizabeth Connolly was using an internet connection to control the Faulkes Telescope in Hawaii. During her half-hour observing session, she briefly turned the telescope to where the new planet had been discovered. After taking a photograph with the 2-metre telescope, she compared the new image with an old image of the same patch of sky. The new planet was clearly visible as a faint smudge amongst other background stars, where before there had been nothing. Asked what she felt about sighting the new planet, Elizabeth, a student at Loreto Grammar School, Omagh, said, "Wow, its cool! Its amazing how a little tiny dot can make you realise your complete insignificance in the universe!"
2003 UB313 was discovered by a team of Californian astronomers on January 5, 2005 from images taken in 2003, and the discovery was announced on July 29, 2005. It has been described as "definitely bigger than Pluto", and is the largest known member of a family of objects orbiting the Sun beyond Neptune. Right now, 2003 UB313 is three times further from the Sun than Neptune, and 97 times farther from the Sun than Earth. Since the discovery of Pluto in 1930, the solar system has contained nine planets. Being larger than Pluto, 2003 UB313 might now be considered as the tenth planet in the Solar System, and is already being described as such by NASA. However, the status of Pluto as a planet has been subject to debate for some time. Both Pluto and 2003 UB313 are considerably smaller than the Earth and quite unlike the giant outer planets Uranus and Neptune. Also, they travel in orbits that are quite unlike the other planets. So what is a planet? The International Astronomical Union, which adjudicates on all matters astronomical, has been reviewing the definition of the term. Whether Pluto remains a planet, and whether it will be joined by a new family of outer planets or whether these ghostly wanderers will be downgraded, is a question not just for astronomers, but for everyone. Meanwhile, 2003 UB313 awaits a real name rather than just a number.

Airborne thermometer to measure Arctic temperatures

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
