Bacterial defense policies

14-10-2014

High-resolution cryo-electron microscopy has now revealed in unprecedented detail the structural changes in the bacterial ribosome which results in resistance to the antibiotic erythromycin. Multiresistant bacterial pathogens that are insensitive to virtually all available antibiotics are one of ...

Tracing how the embryo takes over

07-03-2014

Embryonic development is initially controlled by maternal genetic information stored in the egg. LMU researchers now describe a methodology that allows the succeeding activation of the zygotic genome to be mapped at high resolution. In multicellular organisms, the earliest steps in embryonic ...

200-year long dispute resolved: First direct evidence that elemental fluorine occurs in nature

09-07-2012

Fluorine is the most reactive chemical element. That is why it is not found in nature in its elemental form, but only in compounds, such as fluorite – that was the accepted scientific doctrine so far. A special fluorite, the “fetid fluorite” or “antozonite”, has been the subject of many ...

High-resolution measurement of photocurrents

18-06-2012

The continuing trend toward miniaturization in electronics demands the use of new materials. Components made of carbon nanotubes may meet this need – and the properties of single nanotube devices can now be characterized with the required resolution. Given the demand for further miniaturization ...

A nanoear to listen into the silence

Gold nanoparticles detect tiny acoustic vibrations

20-01-2012

How noisy is a walking flea? What sorts of sound waves are caused by motile bacteria? Physicists at the Nanosystems Initiative Munich (NIM) have managed for the first time to detect sound waves at such minuscule length scales. Their nanoear is a single gold nanoparticle that is kept in a state of ...

White laser pulses with precisely tailored waveform enable the control of electrons in the microcosm

12-09-2011

An expedition through the fast-paced microscopic world of atoms reveals electrons that spin around at enormous speeds and have gigantic forces are acting on them. Monitoring the ultrafast motion of these electrons requires ultrashort flashes of light. However, in order to control them, the ...

Snapshots of laser driven electrons

17-03-2011

Physicists of the Laboratory of Attosecond Physics at the Max Planck Institute of Quantum Optics succeeded in the first real-time observation of laser produced electron plasma waves and electron bunches accelerated by them. Flocking behavior does not only exist among birds, insects or fish; ...

In search of a new theory of photosynthetic energy transfer

10-12-2010

Photosynthesis, the formation of energy-rich chemical compounds with the aid of sunlight, is fundamental to life on Earth. In plants, sunlight is collected by so-called antennal complexes, consisting of proteins bound to the green pigment chlorophyll. The chlorophyll captures the light energy and ...

Novel process for DNA labeling

06-10-2010

For the first time, baseclick GmbH, a start-up company spun off from BASF SE and Ludwig-Maximilians-Universität Munich, is making its newly developed process for labeling nucleic acids (DNA and RNA) available to customers. The company recently signed licensing agreements for this technology with ...

Mapping the structure of protonated water clusters

26-08-2010

Water molecules are continuously forming short-lived networks called clusters. These can in turn bind positively charged protons, and such clusters can provide active functional groups in proteins. Using infrared spectroscopy, it is possible to determine the bond strengths, geometrical structures ...
