Researchers from the University of Bonn discover bats may be a common source of many viral diseases Where do viruses dangerous to humans come from, and how have they evolved? Scientists working with Prof. Dr. Christian Drosten, Head of the Institute for Virology at the Universitätsklinikum Bonn, have made significant progress in answering this question. "We already knew from prior studies that bats and rodents play a role as carriers of paramyxoviruses," said Prof. Drosten....

Researchers study special forms of a conotoxin that blocks transmission of pain signals Hidden in the mud, the cone snail Conus purpurascens lies in wait for its victims. It attracts its prey, fish, with its proboscis, which can move like a worm, protruding from the mud. Once a fish approaches out of curiosity, the snail will rapidly shoot a harpoon at it, which consists of an evolutionarily modified tooth. The paralyzed victim then becomes an easy meal. It takes the venomous cone snail...

Geologists at the Universities of Bonn and Cologne have come up with a new idea as to how the earliest continents were formed The earth's structure can be compared to an orange: its crust is the peel supported by the earth's heavy mantle. That peel is made up of a continental crust 30 to 40 kilometers thick. It is much lighter than the thinner oceanic crust and protrudes from the earth's mantle because of its lower density, like an iceberg in the sea. "According to the current theory, the...

Researchers from the University of Bonn find decrease in activity of the brain's 'fear center' The study, which was supported by the German Research Foundation, brought together scientists from the Universities of Bonn and Köln, as well as from the Charit© in Berlin. 28 younger persons who had been smoking for quite a number of years and an equal number of non-smokers participated in this study. Each of the subjects was shown photos of happy, fearful and neutral faces while their...

Scientists have found a way to take the temperature of dinosaurs that have been extinct for millions of years. But since you cannot take their temperature like you do with humans, the researchers did the next best thing -- study dinosaur teeth, which can reflect body temperature. What they found is surprising. Studying the teeth of the long-necked Brachiosaurus, they discovered it had a temperature of about 100.8 degrees F and the smaller Camarasaurus had a temp of 98.3 degrees. Humans...

Researchers propose a new target structure for highly effective 'deep brain stimulation' Nearly ten percent of all cases of depression are so severe that the patients do not respond to any established treatment method. Targeted stimulation of areas in the brain using a type of "brain pacemaker" has recently raised hopes: According to initial studies, half of patients with the most severe depression treated in this manner see a significant improvement in mood. Physicians from the University of...

Completely new source of light for many applications Physicists from the University of Bonn have developed a completely new source of light, a so-called Bose-Einstein condensate consisting of photons. Until recently, experts had thought this impossible. This method may potentially be suitable for designing novel light sources resembling lasers that work in the x-ray range. Among other applications, they might allow building more powerful computer chips. The scientists are reporting on their...

Researchers from Bonn and St. Andrews provide an explanation for the discrepancy New stars are born in the Universe around the clock "“ in the Milky Way, currently about ten per year. From the birth rate in the past, we can generally calculate how populated space should actually be. But the problem is that the results of such calculations do not match our actual observations. "There should actually be a lot more stars that we can see," says Dr. Jan Pflamm-Altenburg, astrophysicist at...

A difference in a single gene is associated with a significantly increased willingness to donate Do you like to do good things for other people? If so, your genes might be responsible for this. At least, the results of a study conducted by researchers of the University of Bonn suggest this. According to the study, a minute change in a particular gene is associated with a significantly higher willingness to donate. People with this change gave twice as much money on average to a charitable...

Researchers have discovered more than 700 new species of prehistoric insects in a 50-million-year-old amber deposit in India. The 330 lb. deposit, dubbed Cambay amber, was unearthed in lignite mines in the Cambay Shale on the coast of India's Gujarat province.  It is the oldest evidence of a tropical broadleaf rainforest in Asia, said the international team of researchers from Germany, India and the United States. The bees, termites, spiders, and flies entombed in the newly excavated...
