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.

New exotic particle state puzzles theorists
New exotic particle state puzzles theorists
Scientists of the COMPASS collaboration at CERN have observed a new exotic combination of light quarks. Researcher from the Cluster of Excellence "Origin and Structure of the Universe" of the Technical University of Munich (TUM) had a leading role in the data analysis of the new finding. So far theoretical physicists are not able to correctly describe all characteristics of this exotic new particle.

Dr. Rudolph Perkins Receives Research Grant From Alexander von Humboldt Foundation
Starting this September, Ruperto Carola welcomes US mathematician Dr. Rudolph Perkins, recipient of a research grant from the Alexander von Humboldt Foundation. During his two-year stay, he will explore the theory of numbers. His host is Dr. Gebhard Böckle, director of a research group at the Interdisciplinary Center for Scientific Computing (IWR) at Heidelberg University.

Dark Matter: CRESST searches for "lightweights"
The Earth, planets, stars, and galaxies form only the visible portion of the matter in the universe. Greater by far is the share accounted for by invisible "dark matter". Scientists have searched for the particles of dark matter in numerous experiments - so far, in vain. With the CRESST experiment, the search radius can be considerably expanded: The CRESST detectors are being overhauled and are then able to detect particles whose mass lies below the current measurement range.

Molecular models come to the aid of chocolatiers
For many it's simply irresistible and their favorite candy: chocolate. Its success is presumably due not only to its taste but also to its smooth texture, which is achieved by a process known as conching and the addition of lecithin. Scientists at the Technical University of Munich (TUM) have now explained how all the ingredients interact at the molecular level and what gives chocolate its characteristic texture.

The symmetry of the universe
The symmetry of the universe
Our existence is still a great mystery in theoretical physics. Why did anti-matter disappear almost completely from our universe, whereas matter did not? Scientists are attempting to solve this mystery at the particle accelerator of the major European research institute at CERN. The ALICE collaboration has now published the most precise measurement of the properties of light atomic nuclei and anti-nuclei ever made in the "Nature Physics" journal.

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.

Arylboronates made easy
08/20/2015 Abandoning expensive and toxic materials in chemical synthesis: This is the goal pursued by scientists at the University of Würzburg. In the magazine "Angewandte Chemie", they describe a new way to achieve this goal, a surprise included. Arylboronates are important base materials for the industrial fabrication of countless products, including pharmaceutical drugs, chemicals for agriculture or liquid crystals for displays.

Latest Findings on Skeletal Structure of the Cell
Scientists at Freie Universität Improve Methods for Imaging the Organization of the Cytoskeleton Scientists at Freie Universität Berlin and the Dutch University of Utrecht have developed a method for mapping the structure of the cytoskeleton. The cytoskeleton is the backbone of every cell of the human body.

How Human Cells Can Dissolve Damaging Protein Aggregates
Cellular repair systems can dissolve aggregated proteins and now Heidelberg researchers have successfully decoded the fundamental mechanism that is key to dissolving these protein aggregates in human cells. Their in-vitro experiments uncovered a multi-stage biochemical process in which protein molecules are dissolved from the aggregates.

The eight-step path
LMU chemists report the first total synthesis of the natural product epicolactone, which is found in certain species of endophytic fungi. The data shed light on its biosynthesis and reveal its relationship to the pigment purpurogallin. Epicolactone is produced by an endophytic fungus which grows on agriculturally important tropical plants such as the cocoa tree.

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.
