Scientists have discovered a new family of molecules that work together to precisely remove unwanted DNA during reproduction in single-celled, freshwater organisms called ciliates.
With age, expression of a small molecule that can silence others goes way up while a key signaling molecule that helps stem cells make healthy bone goes down, scientists report.
A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has presented the notion of 'DNA Phase Separation', which suggests that the DNA within the nucleus may trigger phase separation, like oil in water.
University of Oregon chemists have created a new class of fluorescent dyes that function in water and emit colors based solely on the diameter of circular nanotubes made of carbon and hydrogen.
A Rutgers-led team has discovered how plants harness microbes in soil to get nutrients, a process that could be exploited to boost crop growth, fight weeds and slash the use of polluting fertilizers and herbicides.
A simple blood test could be used in the future to predict the health and productivity of dairy cows, research by experts at the University's Roslin Institute and Scotland's Rural College shows.
The effects of genetic mutations are strongly influenced by pre-existing genetic differences among individuals and the environment, a study finds.
New research raises the possibility that a wider group of people battling substance use disorders may benefit from a Scripps Research-developed relapse-prevention compound than previously thought.
Scientists from EPFL and the University of Geneva have discovered a 'code' of architect genes that are expressed in specific combinations during the development of hands and fingers. The study decrypts developmental gene expression at the level of the single cell in developing limbs and expands our understanding of the genetics behind growing limbs.
Researchers from the Salk Institute found that an important quality control mechanism in baker's yeast is closely connected to hypomyelinating leukodystrophy, a debilitating disease found in children. The findings could indicate a therapeutic approach for this rare disease, as well as for multiple sclerosis and other neurodegenerative diseases.
