There’s more to your DNA than your DNA. We are now becoming aware of the epigenome. While DNA controls you, your epigenome may help control your DNA, or rather, it can have an extensive impact on how your DNA is expressed.

In first-of-their-kind experiments performed at the American X-ray laser LCLS, a collaboration led by researchers from the Paul Scherrer Institute has been able to precisely follow how the magnetic structure of a material changes.

Cage Fitness and other mixed martial arts-inspired workouts mimic the structure of a championship MMA bout -- minus the injury.

Negative ions play an important role in everything from how our bodies function to the structure of the universe.

Researchers at UC Santa Barbara have developed a new and highly efficient way to characterize the structure of polymers at the nanoscale – effectively designing a routine analytical tool that could be used by industries that rely on polymer science to innovate new products, from drug delivery gels to renewable bio-materials.

It covers over two thirds of our planet, is essential for life on Earth and its chemical formula is one of the few most people can name, but we still have much to learn about the structure of H2O. Now, scientists working in Grenoble have developed a new technique using oxygen isotopes to study in detail the structure of disordered oxide materials such as water in biological processes or glasses in lasers and telecommunication devices

(PhysOrg.com) -- 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 structure of these light flashes, or light pulses, needs to be tamed as well.

(PhysOrg.com) -- Knowing the structure of a molecule is an important part of understanding it, but quite often it’s even more important to know how the molecule moves -- more specifically, the vibrational dynamics that drive and control its interactions with other molecules in chemical reactions. That’s particularly true of proteins, the enormously complex molecular structures found at the heart of important life processes such as cell signaling, ion transport, and other functions. But most of the available techniques for studying the vibrational properties of a protein run into some vexing limitations, especially when probing the lower frequencies at which the proteins actually do their job.

RIKEN and the Japan Synchrotron Radiation Research Institute (JASRI) have successfully produced a first beam of X-ray laser light with a wavelength of 1.2 Angstroms.

A new way of understanding the structure of proteins, polymers, minerals, and engineered materials will be published in the May 2011 issue of the journal Nature Materials. The discovery by two Penn State University researchers is a new type of symmetry in the structure of materials, which the researchers say greatly expands the possibilities for discovering or designing materials with desired properties. The research is expected to have broad relevance in many development efforts involving physical, chemical, biological, or engineering disciplines including, for example, the search for advanced ferroelectric ferromagnet materials for next-generation ultrasound devices and computers

(PhysOrg.com) -- Physicists at UCLA set out to design a better transistor and ended up discovering a new way to think about the structure of space.
