Researchers used lists of non native plants to estimate the number of invasive species on forty five caribbean islands. They found that larger islands tend to have more exotic species than smaller ones, but cuba is home to hundreds fewer such species than expected for its size. The team found that mass tourism seems to favor the introduction of invasive plants and tourists carry seeds in their bags or on their shoes. Next up we look at how regenerative medicine may be able to help treat a debilitating and often fatal bowel condition.
The surprising structure of protons, and a method for growing small intestines for transplantation.

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.
