FEATURES
Focused Molecular Imaging Using Radiotracers Locating, imaging and quantifying concentrations of specified molecules deep within the body are essential in medicine and in drug discovery and development. Together often called molecular imaging, these tasks typically are performed by attaching radioactive atoms, or radiotracers, to the molecules and observing the radiation externally. Another molecular imaging modality uses fluorescent...
Getting in Deeper Thanks to microendoscopic research and technology innovations, patients could be in for a new set of close-ups. Several groups of investigators are working to implement optical biopsies, in which the...
Prospects for Photodynamic Therapy in Dentistry Photodynamic therapy (PDT) involves the use of a photosensitizer that is activated by illumination in the presence of oxygen. The exposure of the photosensitizer to light results in the formation of...

Automated MRI technique could expedite Alzheimer’s diagnosis An automated system to measure brain tissue volume with MRI has shown promise as a tool for the rapid and accurate diagnosis of Alzheimer’s disease at an earlier stage, according to a study conducted...
Optical trap technique measures single-molecule forces The molecular mechanics of the cell are a frontier that scientists still are striving to learn more about. For example, the cell’s cytoskeleton — which provides structural integrity — is of interest...
New method can create fluidic channels with unusual shapes Most micro- and nanofluidic chips contain channels with flat rectangular sides. A novel technique called “nanoglassblowing” can create curved micro- and nanochannels from glass, including funnels...
A femtosecond laser can be a pacemaker for heart muscle cells Femtosecond lasers are used in applications as diverse as optical microscopy and lasik eye surgery. Now scientists at Osaka University in Japan have discovered that femtosecond laser pulses can cause...

Microscope reveals ‘Nutcracker Man’ may not live up to his name Half a century ago, scientists uncovered the 1.2- to 2.3-million-year-old bones of Paranthropus boisei in eastern Africa. It had the flattest cheek teeth and thickest enamel of any known human ancestor. The size and shape of the teeth, jaws and cranium led the scientists to conclude that P. boisei ate hard and brittle foods such as nuts, seeds, roots and tubers. Thus, P. boisei became known...
