Scientists Solve Mystery of How and When DNA Replicates

A research team led by Florida State University scientists has demonstrated that there are specific points along the DNA molecule that control replication. The study appears in the journal Cell. Sima et al found that cis-regulatory elements control the 3D compartmentalization, architecture of the genome, and replication timing in a …

Scientists Sequence Genome of Himalayan Marmot

Researchers have for the first time mapped the genome of the Himalayan marmot (Marmota himalayana), a hibernating mammal that inhabits the high-elevation regions of the Himalayan mountains. Published in the journal iScience, the results hint at the genetic mechanisms underlying high-altitude adaptation and hibernation. The Himalayan marmot (Marmota himalayana). Image …

Genetically Modified Houseplant Can Clean Indoor Air

A team of scientists at the University of Washington has genetically modified a common houseplant, the pothos ivy (Epipremnum aureum), to efficiently remove two toxins — chloroform and benzene — from the air around it. The transgenic plant expresses a protein that transforms toxins into molecules that the plant can …
