A human genes makes mice stand upright, but does that contribute to language?
Researchers have found that the human version of the NOVA1 gene altered a molecular process that alters how proteins are mixed and matched to create diverse proteins. To study the effects of the change, researchers used CRISPR gene editing to engineer mice carrying the human version of Nova1. They also found the human version affected…

Why is she in pain now that her disease has been cured?
US Food and Drug Administration (FDA) approved two gene therapy treatments for sickle-cell disease last year, including the first CRISPR-based genome-editing therapy the agency has ever authorized. Both stem-cell transplants and gene therapy require chemotherapy before the treatment. Three rounds of chemotherapy and other treatments drove her cancer into remission, but she still struggles with…

The massive ice sheet in Greenland is starting to melt
Scientists at the Norwegian Research Center (NORCE) have discovered a new kind of anti-CRISPR system based on RNA, which neutralises viruses by mimicking a part of the CRISPR-Cas system. The team claimed that this is the first case of anti-CRISPRs protecting viruses by mimicking a part of CRISPR-Cas system. The researchers hope it will lead…

Crispr is being used to Cure HIV
A US-led team has used genome-editing technique CRISPR-Cas9 to alter immune cells to fight cancer in a mouse model. The research, which was conducted at the University of Pennsylvania’s Burnham Institute for Medical Research, was published in Nature Communications on Monday. The mice were injected with immune cells from their own bone marrow to treat…

The resurrection of a bird that has been extinct for a long time is being planned by scientists
Scientists at the University of California, Santa Cruz and Colossal Labs are decoding the genome of the Nicobar pigeon (Caloenas nicobarica), the dodo’s closest living relative, in hopes of bringing it back. They would edit DNA sequences in the pigeon’s genome to match those of dodos using tools such as CRISPR. They’d use these genes…
