New simulations show how a dynamo in collapsed massive stars can build the strong magnetic fields needed to power extremely energetic blasts.
An international team of scientists, headed by researchers at UC San Diego School of Medicine and UC San Diego Moores Cancer Center, report that decreases in a specific group of proteins trigger changes in the cancer microenvironment that accelerate growth and development of therapy-resistant cancer stem cells (CSCs). The findings are published Nov. 30 by Proceedings of the National Academy of Sciences.
Researchers at the University of Louisville have described the role of TNF receptor-associated factor 6 (TRAF6), an adaptor protein and E3 ubiquitin ligase, in ensuring the vitality of stem cells that regenerate muscle tissue.
When public schools in Wake County, N.C. switched from a school assignment policy based on race to one based on socioeconomic status, schools became slightly more segregated but the achievement gap lessened, according to new research from Duke University's Sanford School of Public Policy.
In a new article in Armed Forces & Society, researcher Amitai Etzioni discusses the dual nature of Freedom of Navigation Operational Assertsions; while they are an important component of the liberal international order and essential to US national security, they are also assertive in nature, overly used, and can easily escalate into dangerous clashes between nations.
When preliminary tests show that a new drug has remarkable effectiveness against a lethal illness, everyone wants to know how it works. A CSHL team reports a surprising mechanism through which an important new drug against leukemia, JQ1, exerts its therapeutic effect.
Researchers at the Translational Genomics Research Institute (TGen) and Barrow Neurological Institute have for the first time identified genetic risk factors that are linked to stress-induced cardiomyopathy (SIC), a rare type of heart disease. Patients with SIC generally show no symptoms until they suffer some form of intense emotional or physiological distress. For this reason the disorder is sometimes referred to as 'broken heart syndrome.'
Johns Hopkins researchers have developed a method to efficiently turn human stem cells into retinal ganglion cells, the type of nerve cells located within the retina that transmit visual signals from the eye to the brain.
Researchers at Brigham and Women's Hospital have developed a genetic model that is yielding new insights into what happens when astrocytes go awry.
A larger portion of Africa is currently at high risk for malaria transmission than previously predicted, according to a new University of Florida mapping study.
