Ringing in the ears and chronic pain enter by the same gate
Ringing in the ears and chronic pain enter by the same gate
Tinnitus and chronic pain have more in common than their ability to afflict millions with the very real experience of "phantom" sensations. Scientists noted similarities between the two disorders more than thirty years ago. Now advances in brain imaging and associated techniques have enabled researchers to begin homing in on their structural and functional bases, revealing what appears to be a central gatekeeping system implicated in both chronic pain and tinnitus.

Capturing light - for the computers of tomorrow
Capturing light - for the computers of tomorrow
Light is ideally suited to data transfer, as it can transmit large quantities of information in a very short time, and is an indispensable part of the IT world of today and tomorrow. However, a stumbling block so far has been the storage of large quantities of data directly in the optical domain. While optical fibre cables - and, with them, data transfer by means of light - have long since become part of our everyday life, data on a computer are still processed and stored electronically.

Overlooked for 30 years: a new kid on the block
A team led by Christian Haass has identified a novel peptide that plays a role in Alzheimer's disease: The previously overlooked eta-amyloid interferes with neuronal function and may antogonize beta-amyloid - a finding that has implications for ongoing clinical trials. Alzheimer's disease is associated with the appearance of characteristic neurotoxic protein aggregates in various regions in the brain.

A Barcode For Shredding Junk RNA
A growing, dividing cell uses most of its energy store to make its "protein factories", the ribosomes. An important player in their "assembly" is the exosome, a molecular shredding machine that breaks down excess ribonucleic acid (RNA). Researchers working with Ed Hurt at the Heidelberg University Biochemistry Center (BZH) have discovered how the exosome identifies its target RNA.

Activated Neurons Produce Protective Protein against Neurodegenerative Conditions
Activated Neurons Produce Protective Protein against Neurodegenerative Conditions
Activated neurons produce a protein that protects against nerve cell death. Hilmar Bading and his group at Heidelberg University's Interdisciplinary Center for Neurosciences have found out how this effect comes about and defined a crucial player. "We already knew that brain activity promotes neuroprotection," Prof. Bading says.

Stroke: News about platelets
Stroke: News about platelets
Platelets play a key role in strokes: They can even drive nerve cells in the brain into a kind of suicide mode, as scientists from the University of Würzburg now report in the journal "Blood". A stroke typically develops as follows: A blood vessel supplying the brain with vital oxygen and nutrients is blocked by a blood clot, resulting in nerve cell death.

Global collapse in huge songbird population
Global collapse in huge songbird population
With its canary-yellow colouring, the yellow-breasted bunting - about the size of a sparrow - is one of the more striking species of songbirds. Until a few years ago it was one of the commonest birds found in northern Europe and Asia. Since then, however, ornithologists have recorded sharp declines in many regions.

The Regulating Hand in Ribosome Formation
Ribosomes, which use a fixed genetic programme to manufacture cell proteins, also form according to a strict hierarchical plan. In an interdisciplinary approach, the research teams of Ed Hurt of the Heidelberg University Biochemistry Center (BZH) and André Hoelz of the California Institute of Technology (Caltech) in Pasadena (USA) have decoded the mechanism that regulates this process.

Signal replicas make a flexible sensor
LMU researchers have shown how signals from the spinal cord adjust the sensitivity of hair cells in the inner ear to accommodate shifts in head position associated with active locomotion - thus ensuring that balance is maintained. Fluorescence image showing two nerves (stained in red and green), which are responsible for transmitting information from the hair cells to the brain and from neurons (small green dots) that alter hair cell sensitivity, respectively.

New Findings: Variability Helps Mammals to Become Invasive From the time humans began discovering and conquering new continents, they also started transporting animals and plants around the world and releasing them in locations where they had never been before. Most of these alien species died out quickly, but many established populations and some even multiplied and became invasive, causing tremendous economic and environmental harm.

Revolution averted
Who came first - sponges or comb jellies? A new study by an LMU team reaffirms that sponges are the oldest animal phylum - and restores the classical view of early animal evolution, which recent molecular analyses had challenged. The answer to the question of whether the sponges or the comb jellies (also known as sea gooseberries) represent the oldest extant animal phylum is of crucial importance to our understanding of organismic evolution.

Invasion to the inside
In order to multiply, influenza viruses are dependent on cells of a human or animal body. They board those cells, for example all along the lung surface, and their genetic material migrates into the nucleus, where it is replicated. As a result, new viruses come to life. A team led by scientists from the Cells-in-Motion Cluster of Excellence (CiM), University of Münster, has now, for the first time, succeeded in visualizing structures of the viral genome inside of human cells by light microscopy.

Spin-off Eliminates Animal Testing
Chemical, medication and cosmetic manufacturers are obligated to test their products for possible health risks using appropriate means, as stipulated by various European guidelines. Animal testing is frequently used to determine the dangers of such products to the human eye. Aside from ethical reasons, arguments against this form of testing include high costs, delays due to approval procedures, and concerns whether the results from animal testing can be extrapolated safely to human beings.
