Gene Editing Lets Scientists Turn Off Sperm Production


At a time when access to reproductive health care for women is newly imperiled, the scientific press is revisiting a topic that emerges and fades into the woodwork every few years: male birth control.A new study from Michigan State University published in Nature Communications breaks new ground in approaching a male contraceptive …

Scientists use gene-editing technology to knock out genes in human embryos for first time

For the first time, have used gene-editing techniques on human embryos to probe how they develop. The work suggests that a protein called OCT4 has additional roles in human embryos compared with those of mice. But biologists say it is more …DNA editing in human embryos reveals role of fertility “master …

New gene editing tech promises to be even better than CRISPR

Just when we were getting used to the CRISPR/Cas9 gene editing revolution, a new “fourth-generation” DNA base editor has come along — offering a new way to modify the genetic code that may be safer in terms of reducing potential mistakes. Base editing …’Designer babies’ won’t be a fad. It’s too …

CRISPR Editing in Mice Disrupts Glaucoma-Causing Gene Mutation

NEW YORK (GenomeWeb) – Researchers have used the CRISPR/Cas9 gene-editing tool in mice to disrupt a gene that causes glaucoma. As they also were able to target the gene in human eye cultures, the researchers said their study suggests CRISPR/Cas9 editing could work in the eye. Get the full story …

Doubts Raised about Gene-Editing Study in Human Embryos

Doubts have surfaced about a landmark paper claiming that human embryos were cleared of a deadly mutation using genome editing. In an article posted to the bioRxiv.org preprint server on August 28, a team of prominent stem-cell scientists and Much-Hyped DNA Editing Study Under Fire

Gene editing of human embryos in UK reveals new fertility clue

(CNN) The DNA of human embryos has been altered and studied for the first time in the UK, offering new insight into the early stages of human development. Scientists at the Francis Crick Institute, a medical research center, have identified the role of Editing Embryo DNA Yields Clues About Early …

This Male Birth Control Will Actually Shut Off Your Sperm to Prevent Pregnancy

Now, scientists have discovered a new technique that might bring an end to the quest for male birth control: They’ve discovered a gene that controls sperm production in mice—and they’ve found out they can literally turn this gene on and off, as they reported in Nature Communications. Unlike condoms, which …

Peanut Allergy Gene: Scientists Find DNA Cause Behind Nut Allergies

Scientists have discovered a gene that is linked to peanut allergies, a find that could help doctors treat the medical condition.They reported their research in the Journal of Allergy and Clinical Immunology, pointing the finger at a gene that has already been found to be connected to other allergy conditions. …
