Right after the Mifflin Meteorite fell in SW Wisconsin in April 2010 the Robert A. Pritzker Assistant Curator of Meteoritics and Polar Studies Dr. Philipp R. Heck coordinated an international study to determine the time it spent in space and to calculate its size in space before it got ablated and broke apart in our atmosphere. Now, first results obtained from this study are published as extended abstracts, and were presented in more detail in March at the Lunar and Planetary Science Conference in Texas: The new results show that Mifflin was travelling through space as a small 3 feet object for about 20 Million years before it landed in Wisconsin.

A 2010 issue of Phytotaxa was dedicated to a group of green land plants commonly referred to as bryophytes. A broad consensus confirms that bryophytes may not be monophyletic, but rather represent three paraphyletic lines, i.e., Marchantiophyta (liverworts), Anthocerotophyta (hornworts), and Bryophyta (mosses). Together, bryophytes are the second largest group of land plants after flowering plants, and are pivotal in our understanding of early land plant evolution. A growing body of evidence is now supporting liverworts as the earliest diverging lineage of embryophytes, i.e., sister to all other groups of land plants.
