Dispersion-Relation Fluorescence Spectroscopy Delivers Greater Resolutions to Study Cells

The ability of fluorescence microscopy to study labeled structures like cells has now been empowered to deliver greater spatial and temporal resolutions that were not possible before, thanks to a new method developed by University of Illinois researcher Gabriel Popescu and Ru Wang from his lab. Using this method, they were able to study the critical process of cell transport dynamics at multiple spatial and temporal scales and reveal, for the first time, properties of diffusive and directed motion transport in living cells.

Novel Imaging Technique Provides New Insights into Formation of Heart Defects

As a human fetus develops, its heart has to keep pace with the new body's ever-growing demands. Much of this is controlled by following genetic blueprints, but the embryonic heart also matures in response to the intense stresses of pumping blood.

Optogenetic Interventions May Help Treat Addictive Behavior

Habits are behaviors wired so deeply in our brains that we perform them automatically. This allows you to follow the same route to work every day without thinking about it, liberating your brain to ponder other things, such as what to make for dinner.

Breast-Specific Gamma Imaging Provides Improved Detection of Cancer

Molecular Breast Imaging (MBI), also known as Breast-Specific Gamma Imaging (BSGI), is a procedure that is able to detect breast cancers missed by mammography and ultrasound, particularly in women with dense breasts.

Scattered X-ray Technology May Improve COPD Diagnosis and Therapy

Chronic obstructive pulmonary disease (COPD) is considered the fourth most common cause of death in the United States. Usually the precursor to this life-threatening lung disease is a chronic bronchitis. Partially destroyed alveoli and an over-inflation of the lungs, known as emphysema, are serious side effects. However, the subtle differences in the tissue are barely discernable in standard X-ray images.

MIT Chemists Design Green Fluorescent Protein Equivalent for Electron Mmicroscopy

The glowing green molecule known as green fluorescent protein (GFP) has revolutionized molecular biology. When GFP is attached to a particular protein inside a cell, scientists can easily identify and locate it using fluorescence microscopy. However, GFP can’t be used with electron microscopy, which offers much higher resolution than fluorescence microscopy.

Novel 3D Optical Doppler Imaging Reveals Cocaine-Induced Restricted Cerebral Blood Flow

Researchers from the Department of Biomedical Engineering at Stony Brook University have developed a high-resolution, 3D optical Doppler imaging tomography technique that captures the effects of cocaine restricting the blood supply in vessels – including small capillaries – of the brain.
