New work shows that bacteria (and probably other cells as well) don’t double in mass before dividing. Instead they add a constant volume (or mass) no matter what their initial size. A small cell adds the same volume as a large cell. By following this rule a cell population quickly converges on a common size.
Lihong Wang, PhD, continues to build on his groundbreaking technology that allows light deep inside living tissue during imaging and therapy. In the Jan. 5 issue of Nature Communications, Wang, the Gene K. Beare Professor of Biomedical Engineering at Washington University in St. Louis, reveals for the first time a new technique that focuses diffuse light inside a dynamic scattering medium containing living tissue.
Gaya Amarasinghe, PhD, assistant professor of pathology and immunology and of biochemisry and molecular biophysics at Washington University School of Medicine in St. Louis, has received three grants from the Icahn School of Medicine at Mount Sinai.
Thaddeus Stappenbeck, PhD, MD, and Matthew Ciorba, MD, assistant professor of medicine, both of Washington University School of Medicine in St. Louis, have received a one-year, $152,000 grant from the National Institutes of Health (NIH) and Oregon Health & Science University for research titled “Influence of Gene-environment Interactions on Innate Immune Function.”
New research demonstrates that obesity does not always go hand in hand with metabolic changes in the body that can lead to diabetes, heart disease and stroke. Washington University School of Medicine researchers found that a subset of obese people do not have common metabolic abnormalities associated with obesity, and they don’t develop them when they gain more weight.
Shankar Sastry, PhD, professor of engineering, has been awarded the Hind Rattan Award from the NRI Welfare Society of India. The award recognizes nonresident Indians who have made exceptional contributions to society.
