A team of biomedical engineers at Virginia Tech and the University of California at Berkeley has developed a new minimally invasive method of treating cancer, and they anticipate clinical trials on individuals with prostate cancer will begin soon.
By using a new kind of genomic technology, a new study unveils a special code — not within DNA, but within the so-called “chromatin” proteins surrounding it — that could unlock the mysterious developmental choices made by mammalian cells, allowing them to assume roles as diverse as liver cells and neurons.
In May, Nobel Laureate James D. Watson, the scientist who co-discovered the structure of DNA, became the first person to receive his own complete personal genome — all three billion base pairs of his DNA code sequenced. The cost was $1 million, and the process took two months.
Cold Spring Harbor Laboratory (CSHL) researchers led by Daniel Nolan and Assistant Professor Vivek Mittal have found that bone marrow (BM) derived endothelial progenitor cells (EPCs) play a critical role in the early stages of tumor progression and that eliminating EPCs stops cancer growth.
Scientists at the University of Washington and other members of an international consortium have completed a multi-year research effort that dramatically boosts understanding of how the human genome functions. While previous studies of the human genome have focused mainly on genes, this study provides insight into the non-gene sequences making up the vast majority of the genome.
University of Pennsylvania researchers have created the first three-dimensional optical images of human breast cancer in patients based on tissue fluorescence.
Researchers at the Methodist Neurological Institute in Houston and Weill Cornell Medical College in New York City used functional MRI to determine that songbirds have a pronounced right-brain response to the sound of songs, establishing a foundational study for future research on songbird models of speech disorders such as stuttering, as reported today in Proceedings of the National Academy of Sciences.
For many patients, a visit to the primary care physician tends to be a one-sided conversation. Patients begin by stating one medical problem, and immediately the doctor takes over.
Standards for the use of ultrasound as a screening tool to measure narrowing of the carotid artery may be too aggressive, resulting in some needless follow-up tests and procedures according to researchers at the University of Chicago Medical Center. Narrowing of the carotid can be a precursor to a stroke.
In an early step toward nonsurgical screening for malignant skin cancers, Duke University chemists have demonstrated a laser-based system that can capture three-dimensional images of the chemical and structural changes under way beneath the surface of human skin.
