Affinity capture devices provide a platform for viewing cancer cells and other macromolecules in dynamic, life-sustaining liquid environments A photograph of a polar bear in captivity, no matter how sharp the resolution, can never reveal as much about behavior as footage of that polar bear in its natural habitat. The behavior of cells and molecules can prove even more elusive. Limitations in biomedical imaging technologies have hampered attempts to understand cellular and molecular...

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...

Not to pick up electrons, but tweezers made of electrons. A recent paper by researchers from the National Institute of Standards and Technology (NIST) and the University of Virginia (UVA) demonstrates that the beams produced by modern electron microscopes can be used not just to look at nanoscale objects, but to move them around, position them and perhaps even assemble them. Essentially, they say, the tool is an electron version of the laser "optical tweezers" that have become a standard...

For every medical student, examining specimens under the microscope is part of the syllabus. However, the opening hours of the labs and the number of enlargers are limited. Thanks to a new online platform, students are now able to learn with greater flexibility and independence. Under the microscope lies a specimen of a liver. Deep in concentration, a student is analyzing the structure of the tissue when the university official asks her to finish up — the lab is about to close. This...

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...

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...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
