Scientists at the Technical University of Denmark have invented a technology which may be an important step towards the hydrogen economy: a hydrogen tablet that effectively stores hydrogen in an inexpensive and safe material.
 | | Dr. Tue Johannesen - one of the inventors of the Hydrogen Tablet - proves the safty of the most secure and efficient hydrogen storage in the world. |
With the new hydrogen tablet, it becomes much simpler to use the environmentally-friendly energy of hydrogen. Hydrogen is a non-polluting fuel, but since it is a light gas it occupies too much volume, and it is flammable. Consequently, effective and safe storage of hydrogen has challenged researchers world-wide for almost three decades. At the Technical University of Denmark, DTU, an interdisciplinary team has developed a hydrogen tablet which enables storage and transport of hydrogen in solid form.
“Should you drive a car 600 km using gaseous hydrogen at normal pressure, it would require a fuel tank with a size of nine cars. With our technology, the same amount of hydrogen can be stored in a normal gasoline tank”, says Professor Claus Hviid Christensen, Department of Chemistry at DTU.

Astronomers and students at UK universities and observatories can use their PCs to spot stars as faint as a candle on the Moon using a record-breaking new telescope.
 | | NGC 6744 is a large face-on barred spiral galaxy in the star-rich southern constellation of Pavo. It lies at a distance of approximately 30 million light years, and spans almost 150 000 light years in diameter. NGC 6744 is often considered one of the most Milky Way-like galaxies known. |
The Southern African Large Telescope (SALT), the largest in the southern hemisphere and equal to the largest in the world, was built by partners in six countries including a UK consortium consisting of Armagh Observatory, the University of Keele, the University of Central Lancashire, the University of Nottingham, the Open University and the University of Southampton.
The £11 million SALT project has now released its first colour images from space, five years after construction started. The UK associates, along with partners in Germany, Poland, New Zealand, South Africa and the USA, have been amazed at the quality of the images, which are the first taken by SALT’s new $600,000 digital camera, SALTICAM.
The ‘first light’ sample images were shot during the camera's first trial period of operation, which also achieved SALT's first significant scientific results.

SAN ANTONIO--(BUSINESS WIRE)--Sept. 1, 2005--The San Antonio Botanical Garden will present Dinosaurus Tex: A Giant Adventure. Approximately 60 life-size dinosaurs including some great insect friends will reside peacefully amid prehistoric plants at the 33-acre garden. The exhibit, presented by the SBC Foundation, will run from September 3 through December 4, 2005.

Dinosaurs that will inhabit the earth for those three months will include the Texas state dinosaur Pleurocoelus; a Quetzalcoatlus perched in a forest of cycads and palms; a vicious Bambiraptors looking for prey in a tropical rainforest; the herbivorous 30-foot-long, duck-billed Kritosaurus; a mother Edmontosaurus carefully guarding her eggs; a 6' centipede; two 3' dragonflies; some 12" cockroaches, and of course, the giant, fearsome meat-eating T-Rex. An assortment of activities will enhance interest and educational opportunities every day. Casts of dinosaur footprints invite visitors to contrast size and stride with those of their own feet. A Dino Dig challenges aspiring paleontologists to dig for dinosaur "bones." Dinosaurus Tex Family Days include additional dino crafts, entertainment and activities: September 3, 4 and 5; October 8; November 5 and December 3. Opening weekend festivities will be highlighted by a visit from George Blasing "Dino George." (2) Comments posted about this in the forum

Swarms of millions of locusts have, since Biblical times and until our very own day, been considered a “plague” of major proportions, with the creatures destroying every growing thing in their path.

Until now, it was thought that the directions of these swarms were predominantly directed by prevailing winds. Now, Hebrew University of Jerusalem scientists have shown that a physiological trait of these grasshoppers – namely their polarization vision -- provides them with a built-in source of “surface analysis” – a discovery that could pave the way for efforts to effectively combat this periodic scourge by controlling their natural inclination to fly over land rather than water.
The desert locusts, known scientifically as Schistocerca gregaria, are able to swarm for great distances and in numbers measuring in the millions. During the locust invasion of November 2004 in Israel, it appeared that a swarm came in an easterly direction over Sinai up to the Gulf of Eilat, then turned northward without crossing the water. Only when the swarm reached the northern tip of the gulf did some of them turn again east in the direction of Aqaba and other areas of Jordan, as well as straight north over southern Israel.
This observation led to examination by scientists of the Hebrew University of Jerusalem Department of Evolution, Systematics and Ecology and the Interuniversity Institute for Marine Sciences in Eilat to examine how the locusts were able to identify the gulf water and knew not to fly over it. The research focused on the ability of the locusts to identify polarized light. This is a trait which is lacking in humans but exists among other species, such as fish and insects.
