Microscopy Enables Detailed Insights into Mitochondria
MUNICH, April 28, 2014 — A new microscopy technique combining confocal and two-photon excitation microscopy with in situ pharmacological and genetic manipulation has given researchers insight into how the nervous system responds to disease and injury — at the mitochondrial level. Reactive oxygen species are important intracellular signaling molecules, but their mode of action is complex: In low concentrations, they regulate key aspects of cellular function and behavior; at high concentrations, they can
Agilent Acquires Novelx
SANTA CLARA, Calif., Jan. 25, 2010 - Novelx, a Lafayette, Calif.-based maker of field emission scanning electron microscopes (SEMs), has been acquired by measurement company Agilent Technologies for an undisclosed amo...
TEAM Yields Stunning Images
BERKELEY, Calif., Sept. 11, 2008 -- The world's most powerful transmission electron microscope has been used to produce stunning images of individual carbon atoms in graphene, the two-dimensional crystalline form of carbon that is highly prized by the electronics industry. Using...
Cheaper Desalination Method Found in Nanotubes
LIVERMORE, Calif., May 22, 2006 -- A nanotube membrane created on a silicon chip the size of a quarter may offer a cheaper way to remove salt from water, said the researchers who created it at Lawrence Livermore National Laboratory (LLNL). The nanotubes, special molecules made of...
NIST Polynanotubes Could Become World's Smallest Hypodermic Needles
Feb 3, 2006 — GAITHERSBURG, Md., Feb. 3, 2006 -- Scientists at the National Institute of Standards and Technology (NIST) have created unusually long polymer nanotubes that could one day be used as incredibly tiny hypodermic needles, capable of injecting molecules...
Engineers Question 'Buckyball' Safety
Dec 9, 2005 — NASHVILLE, Tenn., Dec. 9 -- Buckyballs, pure carbon nanoparticles shaped like soccerballs, have shown promise as components of fuel cells, drug delivery systems and cosmetics that delay aging since their discovery in 1985. But in a newly published...
