Scientists explain why the long neck dinosaurs were able to reach such gigantic proportions There is a simple rule of thumb. The larger an animal is, the more time it spends eating. This means an elephant hardly has time to sleep. It spends 18 hours every day satisfying its huge appetite. 'This led us to one of the many riddles that gigantism of dinosaurs puts before us,' Professor Martin Sander from the University of Bonn explains. 'They were just so large that a day would have had to have...

Materials based on water ferns could reduce fuel consumption massively The hairs on the surface of water ferns could allow ships to have a 10 per cent decrease in fuel consumption. The plant has the rare ability to put on a gauzy skirt of air under water. Researchers at the University of Bonn, Rostock and Karlsruhe now show in the journal Advanced Materials (doi: 10.1002/adma.200904411) how the fern does this. Their results can possibly be used for the construction of new kinds of hulls with...

Scientists publish new findings on glioblastoma, a tumor particularly difficult to treat Glioblastoma is a guileful enemy. While most of the brain tumor can often be removed surgically, in virtually every case the tumor reappears. One reason for this is that sporadic, infiltrative tumor cells will remain in the brain even after most careful surgery. Researchers at the University of Bonn have now subjected these 'forgotten' cells to closer scrutiny for the first time. While doing this, they...

A group of astronomers [1], led by Tim Schrabback of the Leiden Observatory, conducted an intensive study of over 446 000 galaxies within the COSMOS field, the result of the largest survey ever conducted with Hubble. In making the COSMOS survey, Hubble photographed 575 slightly overlapping views of the same part of the Universe using the Advanced Camera for Surveys (ACS) onboard Hubble. It took nearly 1000 hours of observations. In addition to the Hubble data, researchers used redshift [2]...

Study shows: Nutrition has a direct influence on the immune system Bonn researchers have discovered an elementary mechanism which regulates vital immune functions in healthy people. In situations of hunger which mean stress for the body's cells, the body releases more antimicrobial peptides in order to protect itself. The scientists will publish their results in the journal Nature. T cells, B cells, antibodies are known as the 'SWAT team' of our immune system that intervenes when viruses and...

Geodesy researchers observe the mass distribution of the oceans The calculation of variations in the sea level is relatively simple. It is by far more complicated to then determine the change in the water mass. A team of geodesists and oceanographers from the University of Bonn, as well as from the GFZ German Research Center for Geosciences and the Alfred-Wegener Institute for Polar and Marine Sciences, two centers of the Helmholtz Association, have now, for the first time succeeded in doing...

Genetic defect inhibits fruit flies from being able to store fat -- are there parallels to humans? Scientists at the University of Bonn have discovered a previously unknown fruit fly gene that controls the metabolism of fat. Larvae in which this gene is defective lose their entire fat reserves. Therefore the researchers called the gene 'schlank' (German for 'slim'). Mammals carry a group of genes that are structurally very similar to 'schlank'. They possibly take on a similar function in the...

Bonn physicists take first step towards super-fast search algorithms for quantum computersWhen you toss a coin, you either get heads or tails. By contrast, things are not so definite at the microcosmic level. An atomic 'coin' can display a superposition of heads and tails when it has been thrown. However, this only happens if you do not look at the coin. If you do, it decides in favor of one of the two states. If you leave the decision where a quantum particle should go to a coin like this,...

Bonn scientists discover gene locus associated with deformity Comparing 500,000 snippets of human DNA put scientists from the University of Bonn on the right track. A genetic variant on chromosome 8 occurs with significantly higher frequency in people with cleft lip and palate than in the control group. The results are to be published in the forthcoming issue of the journal Nature Genetics. Cleft lips and palates are among the most frequent innate abnormalities. One in about 700 babies in...

In the early Universe, some galaxies may have stars packed together a million times more closely than in the present day, according to research by a University of Bonn team to be published in a paper in Monthly Notices of the Royal Astronomical Society. In our Galaxy, we are used to the idea that even the nearest stars are light years away from the Sun. But a team of scientists led by Professor Pavel Kroupa of the University of Bonn think things were very different in the early Universe. In...


Word of the Day
cacodemon
  • An evil spirit; a devil.
  • A nightmare.
  • In astrology, the twelfth house of a scheme or figure of the heavens: so called from its signifying dreadful things, such as secret enemies, great losses, imprisonment, etc.
