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.
Purdue University researchers have found a method of identifying biological markers in small amounts of blood that they believe could be used to detect a myriad of diseases, infections and different medical conditions at early stages. The researchers have created microelectromechanical resonators, or small vibrating sensors, that can detect these biomarkers using just a drop or two of blood.
Determining how various treatments and conditions affect the mechanical properties of plant cells could allow scientists to understand plant growth at the cellular level and devise ways to enhance it. In a breakthrough report published in The Plant Cell, a team of researchers introduces an innovative robotic tool that measures the mechanical properties of plant cells with cellular resolution.
