Fluorescent anesthetic compound brings new avenues for drug discovery

A collaboration of University of Pennsylvania and University of Wisconsin chemists and anesthesiologists have identified a fluorescent anesthetic compound that will assist researchers in obtaining more precise information about how anesthetics work in the body and will provide a means to more rapidly test new anesthetic compounds in the search for safer and more effective drugs.

World's first nanofluidic device with complex 3-D surfaces

Researchers at the Commerce Department's National Institute of Standards and Technology (NIST) and Cornell University have capitalized on a process for manufacturing integrated circuits at the nanometer (billionth of a meter) level and used it to develop a method for engineering the first-ever nanoscale fluidic (nanofluidic) device with complex three-dimensional surfaces.

Potential therapeutic strategy for fulminant hepatic failure

Fulminant hepatic failure is a serious clinical disease and may threaten the life of patients. However, because of the damage of mass liver cells, the organ function is often irreversible due to the liver cell degeneration, swelling, or apoptosis.

New molecular force probe stretches molecules, atom by atom

Chemists at the University of Illinois have created a simple and inexpensive molecular technique that replaces an expensive atomic force microscope for studying what happens to small molecules when they are stretched or compressed.

New discovery could lead to new methods to block the transmission of HIV

A team of researchers at Mount Sinai School of Medicine and the UC Davis Center for Biophotonics Science and Technology have for the first time captured on video the transfer of human immunodeficiency virus (HIV) from infected to uninfected T cells through structures called virological synapses.

Examining the infinitesimal - new approach to microscopy

A new approach to microscopy is opening up the wonders of the molecular world, allowing researchers to examine organic molecules and delicate crystals as they grow, atom by atom. Dr Andrew Humhpris, co-founder of the original technology and now Chief Technology Officer of Infinitesima, explains how this University spin-out has turned into a leading-edge company.

Measuring the strength needed to move chromosomes

It's about as long as the width of a human hair and only half that length across. So it's tiny - measured in millionths of a meter - and extremely tricky to manipulate. But the meiotic spindle plays so irresistibly important a role in separating our chromosomes during cell division that scientists are compelled to try to study it.
