A new look at the human brain is beginning to reveal the inner lives of its cellular residents.
The human brain holds a dizzying collection of diverse cells, and no two brains are the same, cellularly speaking. Those are the prevailing conclusions of an onslaught of 21 papers published online October 12 in Science, Science Advances and Science Translational Medicine.
The results just start to scratch the surface of understanding the mysteries of the brain. Still, they provide
The human body is made up of a complex community of trillions of cells of diverse shapes and sizes, all working together to keep you alive. The smallest of these cells, like platelets and red blood cells, are dwarfed by massive muscle cells. When it comes to size, it’s like comparing a shrew to a blue whale.
Now, after collecting data on all of the major types of cells in the body, researchers have revealed a familiar mathematical pattern in
The family of Henrietta Lacks, the Black woman whose cancer cells were taken without consent and used to pioneer numerous medical discoveries, reached a settlement on Monday with a biotechnology company that had used the cells.
In a lawsuit filed in October 2021, descendants of Ms. Lacks, who died decades ago, accused the company, Thermo Fisher Scientific, of selling the cells and trying to secure intellectual property rights on the products the cells were used to help develop without compensating
Hair might go gray when stem cells with wanderlust have their travels interrupted.
Stem cells involved in making the pigment that gives hair its color behave much differently than other stem cells do, researchers report April 19 in Nature. Rather than staying put, these melanocyte stem cells travel up and down hair follicles all while oscillating between two different forms of maturity. But it’s not the unusual behavior that leads to graying. It’s when these stem cells stop their
Yumi’s Cells beendete seine zweite Staffel mit einem offenen Ende und das Internet ist jetzt voller Theorien über eine mögliche dritte Staffel und darüber, ob die nächste Staffel Yumis Geschichte mit ihrer Heirat gemäß der Webtoon-Handlung abschließen wird. Sehen Sie sich hier alle Theorien zu Staffel 3 von Yumi’s Cells an.
Yumi’s Cells mit Kim Go Eun, GOT7-Herzensbrecher Jinyoung und Ahn Bo Hyun wurde in den ersten beiden Staffeln weithin geliebt, und da die ursprüngliche Webtoon-Handlung fortgesetzt wird, bis Yumi
In the theater of the brain, nerve cells have long been cast as the stars, bringing mental scenes to life with their electrical and chemical performances. Yet many of the cellular actors in the human brain are glial cells, presumably the supporting cast and behind-the-scenes stagehands.
In recent decades, though, accumulating evidence has shown that glia are not just minor players that keep the show running. They actually play starring roles in many of the brain’s most important acts, such
If humans are to live on the moon and one day make it to Mars then scientists must come up a way for them to grow their own food.
To that end, astronauts on the International Space Station (ISS) could soon be tucking into a tasty meal of fresh steak — but only if they can perfect the technology of cultivating it from beef cells in microgravity first.
That is just one of the scientific experiments being carried out by
