The landing of perseverance on mars has been three point nine billion years in the making. The crater that the lander landed in was created when a meteor collided mars and made this gigantic crater known as the gizero crater. This mission is particularly interesting because what perseverance is going to do is it's going to basically make little rock piles that will be collected by later missions and brought back to earth.
The surprising structure of protons, and a method for growing small intestines for transplantation.
In this episode:
00:45 Probing the proton’s interior
Although studied for decades, the internal structure of the proton is still throwing up surprises for physicists. This week, a team of researchers report an unexpected imbalance in the antimatter particles that make up the proton.
Short Bowel Syndrome is an often fatal condition that results from the removal of the small intestine. Treatment options are limited to transplantation, but donor intestines are hard to come by and can be rejected by the body. Now researchers may have developed a method to grow a replacement small intestine using stem cells and a small section of colon.
