HABITATS: “Life on the Edge in the Polar North” by Alex Corrigan

In a new feature, our Biotechnology undergraduate team members have each chosen one of the ReelLife Science topics, and researched and written a short article. We hope you enjoy them, learn a little from them and perhaps get some inspiration for your videos! First up is Alex Corrigan with “Life on the Edge in the Polar North”.

Svalbard is an archipelago of three main islands, Spitsbergen, Nordaustlandet and Edegøya in the Arctic Ocean far to the North of mainland Norway. These beautiful but isolated islands are sparsely populated by humans, but are home to a wide variety of specialised animals who eke out a living in the harsh polar climate of the Arctic Circle.

The islands of Svalbard encompass a landscape of high mountain ranges, deep valleys and fjords, with glaciers and ice-flows, which cover up to 60% of the terrain. The archipelago is under the grip of the harsh Arctic Climate , with its midnight sun and total darkness in the winter months. Average winter temperatures can dip as low as -18°C with summers only reaching a frosty 2-4°C.

It’s hard to imagine life flourishing in these conditions, yet it does. Svalbard is a breeding ground for many species of seabirds and also hosts larger creatures such as reindeer, Arctic foxes, polar bears and marine mammals such as walruses and seals. There are no less than seven national parks in Svalbard to protect the largely untouched, yet fragile, ecosystems and habitats.

316 primary and secondary schools around Galway and the island of Ireland, will this morning have received an invitation to take part in the inaugural ReelLife Science schools Science video competition.  The competition aims to involve school children in Science in a fun way, developing their analytical, creative and communication skills.  Teachers and students are invited to choose a Scientific topic to communicate in their own unique way, by making a short (1-3 min) video. ReelLife Science will be awarding €1000 in prizes to the winning schools, who will also be invited to the Galway Science and Technology Festival on November 24th, to see their videos on display to the public.

Videos must reach us by Friday, 25 October and the winners will be announced on November 11th. The winning videos will be displayed on the projects website, Facebook page , and Twitter feed, where regular updates, Science news and blog posts can be found. Additional application forms may be downloaded by primary and secondary schools in Galway city and county here.

The NUI Galway ReelLife Science team wishes everyone taking part in the competition the best of luck. Have fun everyone!

OUR BODIES: The origins and distribution of Red Hair.

With temperatures soaring this week, it’s definitely time to slap on the sunscreen, particularly for those with fairer skin and red hair. But where does red hair come from, what is its genetic basis and where is it most common?

Most people with red hair have two recessive alleles (alleles are different forms of the same genes inherited from your parents) for the gene coding for the MC1R protein. These ‘homozygous recessive’ individuals produce a higher level of the yellow-reddish phaeomelanin pigment to those with two dominant alleles (homozygous dominant) or one dominant and one recessive (heterozygous), where the brown-black eumelanin is more prominent.
