A team of neuroscientists at the University of Pennsylvania has constructed the first whole-brain map of electrical connectivity in the brain based on data from nearly 300 neurosurgical patients with electrodes implanted directly on the brain. The researchers found that low-frequency rhythms of brain activity, when brain waves move up and down slowly, primarily drive communication between the frontal, temporal and medial temporal lobes, key brain regions that engage during memory processing.
Researchers at Duke University have discovered that reducing the use of antibiotics will not be enough to reverse the growing prevalence of antibiotic resistance because bacteria are able to share the ability to fight antibiotics by swapping genes between species. They also show, however, that there are ways to disrupt the gene-sharing process and perhaps reverse antibiotic resistance.
A team of bioengineers and bioinformaticians at the University of California San Diego have discovered how the environment surrounding a tumor can trigger metastatic behavior in cancer cells. Specifically, when tumor cells are confined in a dense environment, the researchers found that they turn on a specific set of genes and begin to form structures that resemble blood vessels.
Human genome editing, 3-D-printed replacement organs and artificial photosynthesis - the field of bioengineering offers great promise for tackling the major challenges that face our society. But as a new article out today highlights, these developments provide both opportunities and risks in the short and long term.
A study of an unusual snapping turtle with one lung found shared characteristics with humans born with one lung who survive beyond infancy. Digital 3-D anatomical models created by Emma Schachner, PhD, Assistant Professor of Cell Biology & Anatomy at LSU Health New Orleans School of Medicine, made the detailed research possible.
Inflammation processes are responsible for the failure of insulin production in diabetes patients. The patients' own immune systems can contribute to treatment of this disease: researchers at the University of Basel and University Hospital Basel have found a feedback mechanism that could help maintain insulin production in overweight sufferers, as they report in the journal Immunity.
A joint effort by breast cancer researchers and bioinformaticians has provided new insights into the molecular changes that drive breast development.
New data published today in Immunity further illuminate how some human beings generate powerful, HIV-blocking antibodies. Led by scientists at the International AIDS Vaccine Initiative (IAVI) and The Scripps Research Institute (TSRI), the results offer important insight into a potential AIDS vaccine design.
University of Colorado Boulder researchers have discovered a potent, drug-like compound that could someday revolutionize treatment of rheumatoid arthritis and other autoimmune diseases.
One of the most difficult to treat cancers - triple-negative breast cancer - may be vulnerable to a new approach, an early study indicates.
