A Barcode For Shredding Junk RNA

Biochemists identify detection signal for breaking down excess ribosomal RNA

31-Aug-2015

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 Prof. Dr. Ed Hurt at the Heidelberg ...

Holocaust survivors pass on trauma to their children’s genes

Pre-conception trauma results in transmission of epigenetic changes from the exposed parents to their children

27-Aug-2015

An international team lead by Rachel Yehuda, professor at Mount Sinai hospital in New York, and for the molecular analyses Elisabeth Binder, director at the Max Planck Institute of Psychiatry in Munich, studied the genes of 32 Jewish individuals who had been held in concentration camps, ...

Sperm navigation in 3D

21-Aug-2015

Scientists from the Center of Advanced European Studies and Research (caesar), an Institute of the Max Planck Society, discovered the principles of how sea urchin sperm navigate in their natural three-dimensional environment. Using photonic techniques, the scientists created chemical “landscapes” ...

Immune system: Help for killer cells

21-Aug-2015

Scientists at the University of Bonn, together with colleagues from the USA and Japan, have shed light on an important immune mechanism. Their work shows how the body provides the important killer cells with a helper in the case of an infection. The study could point the way to better vaccines in ...

Formation of swarms in nanosystems

20-Aug-2015

One of the striking features of self-organization in biomolecular systems is the capacity of assemblies of filamentous particles for synchronous motion. LMU physicists now provide new insights into how such movements are coordinated. Living matter, which consists largely of diverse polymeric ...

Turkish whistling makes asymmetries in the brain disappear

19-Aug-2015

Researchers at the Ruhr-Universität Bochum have debunked the theory that the left brain hemisphere is dominant in the processing of all languages. To date, it has been assumed that that dominance is not determined by the physical structure of a given language. However, the biopsychologists have ...

On the Track of Nanomaterials

Researchers pave the way for realistic risk assessment of nanomaterials in the environment

19-Aug-2015

A wide range of industrially synthesized nanomaterials are present in products we use daily and, in the meantime, are part of our everyday life. Due to their exceptional properties (e. g., increased UV-filtration or stronger adhesion) they are used in clothes, cosmetics, household goods and ...

NO2 air pollution increases allergenicity in ragweed pollen

18-Aug-2015

Pollen of the common ragweed (Ambrosia artemisiifolia) has higher concentrations of allergen when the plant is exposed to NO2 exhaust gases, according to findings of scientists of Helmholtz Zentrum München. In addition, the study indicates the presence of a possible new allergen in the plant. ...

Decisive steps in the initiation of programmed cell death revealed

Tübingen researchers have studied the formation of membrane pores that are critical to start the apoptosis program

18-Aug-2015

When cells age or suffer damage, they are able to actively bring about their own pre-programmed death known as apoptosis. A desensitization of this process determines the change from a normal cell into a cancer cell. On the other hand, an over-functioning of apoptosis is associated to the onset ...
