And today we are back with our science shorts, a glimpse at some exciting stories from the world of science. Take a look at what we have compiled below!
GREENLAND ICE SHEET MELTING AT ALARMING RATE
NASA satellites observed a rapid increase in melted ice from Greenland’s large ice sheet this morning. On only July 8th the satellite observed approximately 40% of the sheet melting, but satellite images from July 25th now show that 97% of the ice sheet has begun melting. This has scientists puzzled, for it is the largest melt scientists have seen in three decades, and this figure greatly surpasses the former figure of 55%. This phenomenon is certain to be useful for studying the effects of climate change for many years to come.
Researchers on the International Space Station will be using pet fish to look at the effects of microgravity on marine life. The aquarium will lie in the Japanese Experiment Module on board the station, where the scientists will study the effects of muscle atrophy, radiation, bone degradation and developmental biology. The habitat is the ultimate in fish luxury, featuring automatic feeding, temperature control. It also comes complete with LED lights, which will stimulate day and night cycles. If you’re curious as to how the water will remain in the tank, scientists inject a small amount of fair into the tank, trapping the water using a grid-like structure at the start of the investigation. This prevents the water from escaping. The scientists would ultimately like to hold amphibians for future study. Talk about out of this world science!
MATH MODELLING THE OLYMPICS
Economists at Ruhr-Universität Bochum have dared to forecast predictions for the Olympic games using political, cultural and geographic models. They have an accurate system; they were 97.4% accurate in the Athens games of 2004 and 96.9% accurate in predicting the Beijing games. Most interestingly, the success of women in the Olympics depends heavily upon their emancipation in society. In their model, societies with a higher work force participation rate, and where women have been allowed to vote for the longest periods of time, were found to be significant in their analysis. If you’re curious, their official predictions are available here.
