Europeans' Appearance Altered Over Five Millennia Of Natural Selection
2014-03-12 05:27:21

April Flowers for redOrbit.com - Your Universe Online A great deal of research has been focused on the factors that have influenced the human genome since the end of the last Ice Age. An international team of scientists—including anthropologists at Johannes Gutenberg University Mainz (JGU), geneticists at University College London (UCL), and archaeologists from Berlin and Kiev—has analyzed ancient DNA from skeletons, finding that natural selection has had a major effect on the human...

How Gene Expression Differs Between Castes In Ants
2014-01-30 11:53:06

Johannes Gutenberg University Mainz Novel or highly modified genes play a major role in the development of the different castes within ant colonies. Evolutionary biologists at Johannes Gutenberg University Mainz (JGU) came to this conclusion in a recent gene expression study. Dr. Barbara Feldmeyer and her colleagues at the JGU Institute of Zoology studied the question how the different female castes arise. An ant colony generally consists of a queen and the workers. Moreover, workers can...

Giants Of Earth's History Still Pose A Wealth Of Riddles
2014-01-14 10:32:20

Johannes Gutenberg Universitaet Mainz Sauropods, the largest land animals in Earth's history, are still mightily puzzling the scientists. These plant-eating dinosaurs with their long necks and small heads could reach a height of 10 meters or more and dominated all other land vertebrates in terms of size. They could weigh up to 80 tons, more than any other known land vertebrate. One question that has been intensely debated is how these giants of the animal kingdom regulated their own body...

Visualization of domain wall motion: Material defects do not impede wall motion at high velocities While searching for ever smaller devices that can be used as data storage systems and novel sensors, physicists at Johannes Gutenberg University Mainz (JGU) have directly observed magnetization dynamics processes in magnetic nanowires and thus paved the way for further research in the field of nanomagnetism. Small magnetic domain wall structures in nanowires can be used to store information...

Transfer Of Flying Quantum Bits At The Touch Of A Button
2013-08-15 10:40:22

Johannes Gutenberg Universitaet Mainz Hybrid technology makes possible highly reliable transmission of photonic qubits By means of the quantum-mechanical entanglement of spatially separated light fields, researchers in Tokyo and Mainz have managed to teleport photonic qubits with extreme reliability. This means that a decisive breakthrough has been achieved some 15 years after the first experiments in the field of optical teleportation. The success of the experiment conducted in Tokyo...

Using Substances From African Medicinal Plants To Stop Tumor Growth
2013-06-10 11:24:22

Johannes Gutenberg University Mainz Experiments using benzophenones derived from plants originating in Cameroon produce evidence that these may be effective against multi-drug resistant cancers African medicinal plants contain chemicals that may be able to stop the spread of cancer cells. This is the conclusion of researchers following laboratory experiments conducted at Johannes Gutenberg University Mainz (JGU). The plant materials will now undergo further analysis in order to...

Biologists at Mainz University achieve repair and read-through of stop mutations responsible for the disease After years of basic research, scientists at Johannes Gutenberg University Mainz (JGU) are increasingly able to understand the mechanisms underlying the human Usher syndrome and are coming ever closer to finding a successful treatment approach. The scientists in the Usher research group of Professor Dr. Uwe Wolfrum are evaluating two different strategies. These involve either the...

Measures Developed To Prevent Wine Indispositions
2012-11-07 12:56:51

Johannes Gutenberg University Mainz Scientists at Johannes Gutenberg University Mainz and the DLR develop measures to prevent health problems associated with biogenic amines in wine Biogenic amines may be one of the factors responsible for symptoms such as headaches, gastro-intestinal disorders, shortness of breath, fall in blood pressure, and even unconsciousness and cardiac arrhythmia in severe cases. Histamine, one of the best known members of this group, can cause serious physical...

Physicists Around The World Cheer The Discovery Of The Higgs Particle
2012-07-13 13:12:28

Success at the world's largest particle accelerator LHC / Experiments involving scientists from Mainz University show first direct evidence of the Higgs boson The mystery of the origin of matter seems to have been solved. At the middle of last week, CERN, the European Organization for Nuclear Research in Geneva, announced the discovery of a new particle that could be the long sought-after Higgs boson. The particle has a mass of about 126 gigaelectron volts (GeV), roughly that of 126...

Physicists at Mainz University significantly improve the calculation method for scattering experiments in particle physics Scientists at Johannes Gutenberg University Mainz (JGU) have set a new record for the calculation of scattering amplitudes. This kind of calculation is used to predict the outcome of accelerator experiments in which high-energy particles collide with one another. However, the calculations become increasingly difficult the greater the number of orders the physicists...

Word of the Day
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
