The physical property of magnetism has historically been associated with metals such as iron, nickel and cobalt; however, graphite — an organic mineral made up of stacks of individual carbon sheets — has baffled researchers in recent years by showing weak signs of magnetism. The hunt for an explanation has not been without controversy, with several research groups proposing different theories. The most recent suggestion, published today, 27 January, in the journal EPL...

The high resolution of Lawrence Berkeley National Laboratory´s Gang Ren When Gang Ren whirls the controls of his cryo-electron microscope, he compares it to fine-tuning the gearshift and brakes of a racing bicycle. But this machine at the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) is a bit more complex. It costs nearly $1.5 million, operates at the frigid temperature of liquid nitrogen, and it is allowing scientists to see what no one...

Field emission devices, which produce a steady stream of electrons, have a host of consumer, industrial, and research applications. Recent designs based on nanotubes and other nanomaterials embedded in plastics show initial promise, but have a number of drawbacks that hinder their wide-scale application. The embedded nanotubes, which serve as the source for the electrons, also enable the normally inert plastic to conduct electricity. This has the desired effect of producing a versatile and...

Proteins caught 'in action' in intact cells using new electron microscopy technique Proteins are literally the movers and the shakers of the intracellular world. If DNA is the film director, then they are the actors. And much can be learned about cell function — and dysfunction — by watching proteins on the move. Until now, scientists have only been able to see this process indirectly. Now researchers at Vanderbilt University in Nashville, Tenn., have come up with a...

Berkeley Lab scientists and colleagues will create an advanced extreme-ultraviolet microscope Moore´s Law, hardly a law but undeniably a persistent trend, says that every year and a half, the number of transistors that fit on a chip roughly doubles. It´s why electronics — from smart phones to flat screens, from MP4 players to movie cameras, from tablets to supercomputers — grow ever more varied, powerful, and compact, but also ever less expensive. Whether the trend...

Mainz method of electron microscopy in international demand / Structural analysis of zeolite published in Science A radical new way of making structures visible at the nano level has been developed at Johannes Gutenberg University Mainz (JGU). This new method makes it possible to determine with precision the arrangement of atoms and molecules in a diverse range of materials from cement to pharmaceuticals. The procedure, which is still in its infancy, comes from the field of electron...

Researchers at the California Institute of Technology (Caltech) have obtained the first high-resolution, three-dimensional images of a cell with a nucleus undergoing cell division. The observations, made using a powerful imaging technique in combination with a new method for slicing cell samples, indicate that one of the characteristic steps of mitosis is significantly different in some cells. During mitosis, two sets of chromosomes get paired up at the center of the cell's nucleus. Then...
