Muscle protein titin plays vital role in Frank-Starling mechanism

Researchers at Illinois Institute of Technology and Loyola University have discovered new clues in the 100-year-old mystery of the Frank-Starling law of the heart: What makes the heart contract more strongly at longer lengths given the same level of calcium activation?

Using Single-Molecule Studies to Understand Cellular Processes: An Interview with Professor W. E. Moerner

Single fluorescent molecules provide a local nanometer-sized probe of complex systems. We can measure the motion of the single molecule, use them to achieve imaging on a scale down to 20 nanometers, or we can infer aspects of the behaviour of the object under study by the details of the light that is emitted.

Larger crystals of bacteriorhodopsin protein grow by consuming smaller crystals around them

A group of biophysicists from Moscow Institute of Physics and Technology and their international colleagues have studied the crystallization of molecules of the membrane protein bacteriorhodopsin. The scientists have demonstrated that the larger crystals of the protein grow by "consuming" smaller crystals around them and creating "depletion zone" around themselves.

New computed tomography method provides internal view of human tooth

Both in materials science and in biomedical research it is important to be able to view minute nanostructures, for example in carbon-fiber materials and bones. A team from the Technical University of Munich, the University of Lund, Charité hospital in Berlin and the Paul Scherrer Institute have now developed a new computed tomography method based on the scattering, rather than on the absorption, of X-rays.

New smartphone-based device can reliably perform molecular diagnoses at low cost

NIBIB-funded researchers at the Massachusetts General Hospital have developed a smartphone-based device that can reliably carry out molecular diagnoses in under an hour for approximately two dollars per patient. The device could enable point-of-care cancer diagnostics in low- to middle-income or remote areas, which often have high rates of mortality from cancer due to missed opportunities for treatment.

Worldwide Protein Data Bank symposium focuses on multi-scale structural biology

The symposium titled with "Integrative Structural Biology with Hybrid Methods" is held focusing on the multi-scale structural biology, which aims to analyze structures of protein molecules and their assemblies, cellular machines, organelle, and even living cells and organisms by the hybrid methods, integrating many different technologies, such as chemical cross-links, MS spectrometry, FRET, Super-resolution microscopy, X-ray diffraction, NMR, and Computer modeling, in addition to Cryo-electron microscopy that has been attracting much attention these days.

Scientists find key to light-induced color change in fish skin

The neon tetra fish from the Amazonas River, along with some reptiles, amphibians, and other fish, takes advantage of structural colors in its skin to change its appearance in response to a triggering signal. In the light-adapted state, its lateral stripe shimmers blue-green, in the dark it is indigo. Scientists from Israel have now found an unambiguous answer to how this intriguing mechanism works. They present their results, which favor the so-called "Venetian blind" model, in the journal Angewandte Chemie.
