Arctic Seafloor Algae Helping to Reveal Historic Sea Ice Conditions

Professor Jochen Halfar

Arctic sea ice is currently declining at an alarming rate. Yet, owing to a lack of observations, we know very little about the long-term evolution of sea-ice prior to the 1970s. Jochen Halfar's research is therefore concerned with finding pink crusts of calcified algae on the Arctic sea floor that his group uses as archives of past sea ice cover. The algae lay down yearly growth bands - similar to tree rings on land - and according to the duration of sea ice cover each year, the thickness of growth bands fluctuate year by year.

Zhenfu Zhang, a graduate student with the Gradinaru Lab, has been awarded a  travel grant from the Biophysical Society of Canada. Zhang's work on single-molecule dissection was recognized at the Society’s annual meeting, which took place in Winnipeg in June 2016. This is the second travel grant awarded to the Gradinaru Lab. Earlier this year, PhD candidate Greg Gomes was awarded a Trainee Travel Award by the BSC’s meeting in February 2016.

Professor Peter Mahaffy Speaks at the E.A. Robinson Lecture

Professor Peter Mahaffy presented a talk at the inaugural E. A. Robinson Lecture on May 27, 2016. With opening remarks from Professors Claudiu Gradinaru and Judith Poë, approximately one hundred people were in attendance. The talk was attended by Dr. E. A. Robinson for whom the lecture series is named. Entitled " Guiding Human Development on a Changing Planet: A Role for Science Education?", the talk was well received for its exploration of new teaching models to enhance engagement and problem solving among first year chemistry students.

Phages are viruses that infect bacteria and structurally are composed of a head and a flexible tail. The head contains all of the phage genetic information and the tail is involved in attaching the phage to the bacterial host and also provides the pathway for transmission of the phage DNA into the bacteria. Replication of phages requires correct packaging of the head and involves the function of the terminase complex and a metal binding DNA endonuclease, known as gp74, is our phage of interest.
