Researchers obtain new results on knockout reactions at HIRFL-CSR

Researchers from the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) and their collaborators have systematically measured the knockout cross sections of neutron-rich carbon isotopes at the intermediate- ...

Molecule regulating sperm motility discovered

About 120 million unintended pregnancies occurred each year between 2015 and 2019 worldwide. While there are oral contraceptives for women, the development of oral contraceptives for men has not been successful. Now, a team ...

Novel switch protein that 'turns on' sperm for fertilization

For a sperm to fertilize an egg, the sperm must first mature in a man's epididymis. Now, an international team of researchers has identified a chain of events in which a protein secreted by the testis travels in the luminal ...

Research shows the way to more efficient EPO production

To many people, EPO rhymes with doping and cycling. But in fact, EPO is an important medical drug. This hormone works naturally in the body by stimulating red blood cell production. Patients suffering from anemia caused by ...

Changes to RNA aid the process of learning and memory

RNA carries pieces of instructions encoded in DNA to coordinate the production of proteins that will carry out the work to be done in a cell. But the process isn't always straightforward. Chemical modifications to DNA or ...

Faster, more efficient CRISPR editing in mice

University of California, Berkeley scientists have developed a quicker and more efficient method to alter the genes of mice with CRISPR-Cas9, simplifying a procedure growing in popularity because of the ease of using the ...

Highly efficient CRISPR knock-in in mouse

Genome editing using CRISPR/Cas system has enabled direct modification of the mouse genome in fertilized mouse eggs, leading to rapid, convenient, and efficient one-step production of knockout mice without embryonic stem ...
