How a wayside weed builds up explosive force to hurl seeds
Hairy bittercress is one of those plants that hurl their seeds in all directions to spread them effectively. A research team has now discovered that to do this, the plant uses a previously unknown mechanism that makes the seed pods contract and snap.....»»
Discovery of a subset of human short introns that are spliced out by a novel mechanism
The well-known essential pre-mRNA splicing factor U2AF heterodimer (U2AF2–U2AF1) has been identified as mediating early splicing reactions in all introns of different lengths. However, Dr. Kazuhiro Fukumura in the Akila Mayeda lab at Fujita Health.....»»
