After more than 100 years: the puzzle of red blood cell production has been solved

The scientists of the Weizmann Institute of Science and their research partners identified for the first time the cells that are responsible for one of the most basic actions of life - the production of a hormone that gives an order to produce red blood cells; The findings are expected to break new ground for innovative medical treatments in various anemia conditions

The type of side chain affects the anchoring ability of the ring peptide to the cell membrane. Stephanie M. Linker et al. Journal of Medicinal Chemistry 2023 66 (4), 2773-2788

How drugs enter the blood

  • One response
First, the molecule anchors itself to the surface of the membrane, before it penetrates the membrane in a direction perpendicular to it. In the next step, it changes its three-dimensional structure while passing through the membrane, rotating once along the longitudinal axis before reaching the opposite side of the membrane, where it exits the membrane again

Researchers succeeded in cracking the formation mechanism of 'microsomes'

  • No comments
Microsomes are recently discovered cellular organelles that are formed by local swelling of membrane fibers formed during cell migration. The microsomes store intracellular biomolecules such as DNA, RNA, proteins and even whole organelles such as the mitochondria and affect the intercellular communication

The survey telescope with the largest field of view in the world was inaugurated these days in Arava

The director of the observatory, Dr. David Polischuk from the Weizmann Institute, says in an interview to the site of the scientist that the telescope is actually an array of 48 small telescopes that together give the opportunity to observe an extremely wide field of view in order to locate planets, supernovae, sources of gravitational waves and more

Mice with two fathers: Scientists create eggs from male cells

  • 2 תגובות
The researchers behind the new study were able to create baby mice with genetic material from two males without any genetic changes. They achieved this by using stem cells to create primordial germ cells (PGCs), which differentiate into sperm and egg.

Genomic study of ancient human remains sheds light on human evolution at the Tibetan plateau

  • No comments
Beginning 4,500 years ago, three very different Tibetan populations occupied the northeastern, south-central, and southern and southwestern regions of the plateau, but they carry a common gene that allows them to function in high, low-oxygen areas. This gene may have come from Denisovan man
