A Cornell researcher, who is a leader in developing a new type of gene editing CRISPR system, and colleagues have used the new method for the first time in human cells -- a major advance in the field. The new...
Aryl polyene are yellow pigments produced by bacteria living in widely varying environments such as soil, the human intestines or other ecological niches. Embedded in the membrane of the bacteria, they serve as protection against oxidative stress or reactive...
New CRISPR-based gene drives and broader active genetics technologies are revolutionizing the way scientists engineer the transfer of specific traits from one generation to another. Scientists at the University of California San Diego have now developed a new version of...
Mutation rates are proposed to be a pragmatic balance struck between the harmful effects of mutations and the costs of suppressing them; this hypothesis predicts that longer-lived body parts and those that contribute to the next generation should have...
The world's elderly population is booming. The number of older people -- those age 60 years or older -- is expected to more than double by 2050 and is growing faster than all younger age groups across the globe. This...
Researchers are reporting new findings on how bacteria involved in gum disease can travel throughout the body, exuding toxins connected with Alzheimer's disease, rheumatoid arthritis and aspiration pneumonia. They detected evidence of the bacteria in brain samples from people...
A protein complex that is involved in nearly every step in the regulatory control of gene expression in cells has now been shown also to play a key role in clearing potential traffic jams in the production of RNA. RNA...
Data from more than 17,000 teenagers show little evidence of a relationship between screen time and well-being in adolescents. The study, published in Psychological Science, a journal of the Association for Psychological Science, casts doubt on the widely accepted...
A new Northwestern University study challenges prevailing understandings of genes as immutable features of biology that are fixed at conception. Previous research has shown that socioeconomic status (SES) is a powerful determinant of human health and disease, and social inequality...
Columbia University scientists, in collaboration with researchers from Nimbus Therapeutics, have demystified a metabolic enzyme that could be the next major molecular target in cancer treatment. The team has successfully determined the 3D structure of human ATP-citrate lyase (ACLY) --...
