Next, the scientists selected animals with the desired mutation in both normal and reproductive cells and bred them for two generations to achieve offspring that were homozygous, meaning each carried two identical copies of the mutated gene. (nih.gov)

Stable, long-term cell lines will enable scientists to study everything from coral bleaching to biomineralization, knowledge that may help protect corals from ongoing climate change. (the-scientist.com)
NIEHS-funded scientists established a new approach to study susceptibility to contaminants during early development using modified sea urchins, which are commonly used to study the mechanisms of early development. (nih.gov)
An NIEHS-funded study was the first to reveal higher personal chemical exposures immediately following Hurricane Harvey compared with an estimated baseline. (nih.gov)
Its model allows technologists and computational biologists to partner with disease-oriented scientists from the inception of each study, and also encourages experimentalists to guide the development of the technologies they need. (gladstone.org)
From the initial beginnings of a tumor, sometimes in the darkness of a still-forming embryo, to a tumor's growth and eventual metastasis to other sites in the body, Whitehead Institute scientists Rudolf Jaenisch, Jonathan Weissman, and Robert Weinberg study the pivotal points in a cancer's growth and spread. (mit.edu)
To understand how the disease develops, scientists need to study what happens to these cancerous "seeds" as the embryo matures. (mit.edu)

Scientists say they have identified a self-destruct button within EBV-associated gastric cancer, and also figured out how to press that self-destruct button. (labonline.com.au)

By mutating one of the two protein domains, scientists have made "nickase" forms of Cas9. (idtdna.com)

But the authors are cautioning fellow scientists that they need to design their tools carefully and perform quality control. (emoryhealthsciblog.com)
To fully reap the benefits of new technologies, scientists need innovative and sophisticated tools and computational methods to analyze data. (gladstone.org)

These "off-target effects" can be detected by comparing the experimental results of an RNAi to all other similar RNAi, enabling scientists to determine if the effect observed is specific to the gene being targeted or if it occurs with all similar RNAi. (nih.gov)

Cas9 unzips the DNA and pushes in the guide RNA. (scitechdaily.com)
