Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight that could inform research into cancer and other diseases.
A new study shows that preexisting autoantibodies in a small subset of the population can allow weakened vaccine viruses to escape control, explaining some adverse events tied to this one kind of Chikungunya vaccine, which is no longer available in the U.S.
Replicative aging of human cells, the result of telomere shortening, is slower at physiological oxygen than at atmospheric oxygen, a difference now shown to be due to low oxygen impairing the ATM kinase response to withered telomeres.
Researchers have learned that the antioxidant glutathione, when operating inside mitochondria, is a key factor enabling tumors to spread from the breast to the lung.
Kivanç Birsoy is uncovering the hidden metabolic pathways that cancer cells exploit. His work could also optimize strategies for using nutrition to improve human health.
A surprising mix of inherited and de novo mutations in 60 genes contribute to 10 percent of CHD cases. Many of these same mutations also contribute to neurodevelopmental disorders including autism.
New imaging reveals a built-in safeguard that allows B cell populations to rapidly expand in germinal centers without introducing deleterious mutations.
