The Birth and Death of Genes
The Birth and Death of Genes
The Antarctic icefish makes an excellent case study for genetic evolution. Genetic changes enable icefish to thrive without hemoglobin and red blood cells and to avoid freezing in the icy ocean.

Antifreeze protein is chock full of ice
The structure of the hyperactive Type I antifreeze (Maxi) showing the extensive array of buried water molecules. The protein is a homodimer of beta-hairpin subunits (colored yellow and orange). Waters are represented by red spheres and their hydrogen-bonding interactions by black dashed lines.

To watch this video on jove.com, click here: http://www.jove.com/video/51185?utm_source=youtube Antifreeze proteins (AFPs) bind to specific planes of ice to prevent or slow ice growth. Fluorescence-based ice plane affinity (FIPA) analysis is a modification of the original ice-etching method for determination of AFP-bound ice planes. AFPs are fluorescently labeled, incorporated into macroscopic single ice crystals, and visualized under UV light.- published: 27 Feb 2014

LabVIEW-operated Novel Nanoliter Osmometer for Ice Binding Protein Investigations
To watch this video on jove.com, click here: http://www.jove.com/video/4189?utm_source=youtube Ice binding proteins (IBPs), also known as antifreeze proteins, inhibit ice growth and are a promising additive for use in the cryopreservation of tissues. The main tool used to investigate IBPs is the nanoliter osmometer. We developed a home-designed cooling stage mounted on an optical microscope and controlled using a custom-built LabVIEW routine. The nanoliter osmometer described here manipulated the sample temperature in an ultra-sensitive manner.- published: 27 Feb 2014

Things You Didn't Know About Antarctica
Things You Didn't Know About Antarctica
1, Antarctica was the last continent to be discovered and was spotted in 1820. The first team to reach the South Pole was led by the Norwegian explorer Roald Amundsen. Caroline Mikkelsen became the first woman to visit Antarctica in 1935 and in January 1979, Emilio Marco Palma became the first child born on the southernmost continent. 2, Antarctica is Earths fifth largest continent, it's covered in ice and is classed as a desert. It owns this classification because Deserts are generally defined as areas that receive less than 10 inches of rain or snow a year. Which puts Antarctica in the desert category. 3, Antarctica holds 90% of the world's ice and if it was to melt away, all of the worlds oceans would rise by 65 metres. This rise would swallow places like London and Venice. most of Denmark and the entire Atlantic seaboard. Florida and the Gulf Coast would require a submarine to visit and San Francisco's hills would become a cluster of islands. Since 1992 it has averaged a net loss of 65 million metric tons of ice a year. 4, Many Antarctic sea creatures have antifreeze in their blood. Creatures such as fish living in the Antarctic waters have a protein in there blood that affects the water molecules so that they cannot freeze. The anti-freeze proteins work better than any man made antifreeze. 5, Penguins are black on top and white on the bottom because when they're cold, they turn there black backs to the sun to generate heat and warm them up. But when they get hot, they turn their white fronts to the sun which reflects heat and cools them down.
