Optogenetic control reveals collective cell behavior
New research led by the Institute for Bioengineering of Catalonia (IBEC) has studied the migratory movement of groups of cells using light control. The results show that there is no leader cell that directs the collective movement, as previously thou.....»»
Scientists discover how TGF-Beta sends its message even while tethered to the cell membrane
For years, scientists have thought that TGF-Beta, a signaling protein that holds sway over an astonishing array of cellular processes from embryonic development to cancer, could only do its work once it escaped a lasso-like "straitjacket.".....»»
Modified nano-sized cell particles found to boost cancer immunotherapy, reduce side effects
Immunotherapy is a type of cancer treatment that uses the body's own immune system to help fight cancer. This is by stimulating the immune response to recognize and attack cancer cells more effectively. The treatment involves using substances that bo.....»»
Beyond displays: Liquid crystals in motion mimic biological systems
Liquid crystals are all around us, from cell phone screens and video game consoles to car dashboards and medical devices. Run an electric current through liquid crystal displays (LCDs) and they generate colors, thanks to the unique properties of thes.....»»
Astronomers detect black hole "starving" its host galaxy to death
Astronomers have used the NASA/ESA James Webb Space Telescope to confirm that supermassive black holes can starve their host galaxies of the fuel they need to form new stars. The results are reported in the journal Nature Astronomy......»»
