Today in 1833, Alfred Bernhard Nobel was born. The Swedish chemist is probably best known as the inventor of dynamite and other, more powerful explosives and for the annual prizes which bare his name. An explosives expert like his father, Nobel invented a safe and manageable form of nitroglycerin he called dynamite in 1866, and later, smokeless gunpowder and gelignite. He quickly amassed a huge fortune, much of which was left to fund the Nobel Prizes. First awarded in 1901, these prizes were for achievements in the areas of physics, chemistry, physiology or medicine, literature, and peace. The sixth prize, for economics, was instituted in his honour in 1969. For a more comprehensive biography click here. For some quotes from the great man, click here.

Back in April 2009 we reported that scientists had discovered the furthest object from Earth - a gamma ray burst 13 billion light years away, spotted by the NASA Swift 3 satellite. But now astronomers have trumped that finding, discovering a galaxy 13.1 billion light years away. The galaxy (brilliantly named UDFy-38135539) was pictured last year by Hubble's Wide Field Camera 3, and was most likely formed a mere 600 million years after the big bang. To measure the distance to the galaxy, the scientists took a spectrum of the object using a spectrograph mounted on the European Southern Observatory's Very Large Telescope in Chile. By analyzing the spectrum, the researchers determined that the galaxy was a distance of 13.1 billion light-years away from Earth. Simple!
On Friday October 8th, twelve Transition Year pupils from St. Columba's headed west for Connemara and Dog's Bay to partake in a Coastwatch Survey. The survey involved patrolling a 2.5 km stretch of coastline, analysing the plants and animals of the shore. Hamish Law described the survey as "a mesmerising walk along the coast watching the waves pummelling the rocks". There was also some time for some R & R, with the pupils being treated to a Murder Mystery Tour on the Saturday evening. The event was organised by Mr Sherwood who was accompanied by Mr. Gibbs on the tour. Below is a series of photos, taken by the pupils, of their work on the shore.

Speckled Wood (Pararge argeria) This dark brown butterfly is most often seen in the lower Deerpark flitting among the oak trees, or sitting on a leaf sunning itself. It does not feed on the nectar in flowers as most butterflies do but on the honeydew secreted by aphids as they suck sap from plants. The lines of black dots, with central white dots, along the outer fringes of its wings make it easy to spot. Its caterpillar is green with light green to cream stripes running the length of its body.
Peacock Butterfly (Inachis io) This is the most colourful butterfly normally seen around the College and it is usually on the wing from June to September. The two large iridescent blue eyes on each of the dark red wings make it very easy to identify. The purpose of these is to startle intending predators when the wings are opened suddenly. The black underwings make it surprisingly difficult to see when at rest. The caterpillar is black with spiny protuberances along its back and orange/brown prolegs: It feeds on nettles which are very common in the Deerpark.
A Prezi is a fancy new type of online presentation tool, one which allows the user zoom in and out, flip 180 degrees and bring their presentations to life. Gone are the days when PowerPoint will forever bore your pupils! We've started to experiment with Prezi's over the last few days and will publish some learning presentations over the coming months. We haven't mastered the free software just yet so please forgive our first attempt - a short presentation, suitable for TY biology, on human evolution. For more information on Prezi click here.

"A physicist is just an atom's way of looking at itself."
"Einstein, stop telling God what to do!"
"If quantum mechanics hasn't profoundly shocked you, you haven't understood it yet."
"We are all agreed that your theory is crazy. The question which divides us is whether it is crazy enough to have a chance of being correct. My own feeling is that it is not crazy enough."

This week's science related YouTube video documents the father and son team who sent a HD camera and an iPhone to space on the back of a weather baloon. The team from New York sent their space bound device floating up just outside Brooklyn and captured 100 minutes of the epic ascent and descent. Luke Geissbuhler and his son Max were able to recover their make-shift device using the GPS equiped iPhone. Amazing! Homemade science at its very best!

Last Thursday, the 7th October, was National Tree Day. Over the last number of years, Mr Swift (along with his Form III CSPE pupils) have planted a tree to mark the occasion and this year was no exception. This year’s tree was the birch and Mr Swift, along with Form III A, planted the tree in the College grounds as part of their CSPE action project. On National Tree Day itself, the whole school were treated to a talk from Nicolo Carlotti and Michael Higgins about the event, representing the pupils in the set, speaking about the birch tree’s origins. The aim of our action project is to raise awareness about the importance of trees and of the National Tree Council of Ireland.
The birch is a tough native Irish tree and can grow in harsh conditions. It has a rapid growth rate in its first twenty years.It matures at forty years and grows to a maximum height of eighty feet. The bark is a bit pinkish in young trees, turning into the whitish silver it is known for, and then the bark darkens with age.

A new cat sized mammal has been discovered in Madagascar, the first new carnivorous mammal to be discovered in over 20 years. Scientists found the creature in the wetlands of Lake Alaotra, the largest lake in Madagascar. Its marsh habitat is under pressure from invasive species and pollution. The animal resembles a mongoose and has been called Durrell's vontsira (Salanoia durrelli) in honour of conservationist Gerald Durrell. It belongs to a family of carnivores called the Eupleridae, only known in Madagascar, and it is likely to be one of the most threatened carnivores in the world.
The animal was first spotted swimming in a lake by a team from the Durrell Wildlife Conservation Trust in 2004 while they were surveying bamboo lemurs. After briefly examining the animal the team suspected they had found a new species and took photographs of it. Subsequent analysis of specimens of another species, the brown-tailed vontsira, in the Natural History Museum's collections, showed that they had found a new species.
Madagascar and the Indian Ocean Islands are known as a biodiversity hotspot because of their great richness in species. They have 7 families of plants, and 15 families of mammals, birds, reptiles, amphibians and fish, which live nowhere else on Earth.

Agriculture, without doubt, is a key catalyst and drive behind both the economic and social sectors in Ireland. Ireland’s mild weather and rich soil content allows Ireland to devote 6.9 million hectares for agricultural purposes, employing over 10% of the Irish workforce. Although exportation is not wholly relied on, when we take into account the reduction of importation costs, the agri-food sector reports over 25% of net foreign earnings. It is thus clear that agriculture in Ireland holds incredible importance and without such emphasis placed upon it, Ireland would lack culturally, socially and of course economically.
Ireland over the years, although moving towards industrialized developments, has held fast to its connection with the farming industry. This is most likely due to the parallel development of Ireland's exporting farm produce. In contrast to this, other countries may produce only enough in order to be self-sufficient, yet still there are some in Europe that will import needed food. This is not to say that the Irish are consistent in their levels of agricultural involvement. A detrimental drop occurred in the percentage of those that work in the agri-sector, in 1926 the impressive 53% saw a decline in 1990 to just under 13.5%. It is also difficult for Ireland to compete with those farms around the world that produce at a much larger scale, if we can compare that of a sheep farm in New Zealand and a farm in Ireland, averaging at 73 acres. These small farms are incredibly vital to Irish agriculture, as with not many large contractors, Ireland relies on these low sized farms as a driving force. This doesn’t mean that Ireland is in somewhat lacking, it is accountable for over 28% of exports in forest and fishery exports, second to Denmark who sits at 34.3%.

Congraulations to Andre Geim, who this year won the 103rd Nobel Prize for Physics with his work on graphene - the thinnest and probably hardest material in the world. But ten years ago, Mr Geim was the proud recipient of an illustrious Ig Nobel Award (see yesterday's post on this year's winners) for his work on levitating frogs - seriously! Yes the flying frogs experiment involved Geim and his team using a popular magnet toy to make a frog float and he succeeded. His research centered around serious ideas about magnetic levitation, a phenomenon best known for its application in Maglev (magnetic levitation) trains, like the Japanese bullet train. Mr Geim became the first person to be award both an Ig Nobel and a Nobel Prize as an individual. Well done!

The Ig Nobel Awards are a humorous alternative to the Nobel Prizes,which are awarded to research that “first makes us laugh and then makes us think”. The awards are given to true scientists who carry out true research but the topic surrounding their research is light, cheerful and a bit silly. Amongst this year’s winners are (adapted from the Guardian):
Psychologists Simon Rietveld and Ilja van Beest at the University of Amsterdam share the award for discovering that ashtma can be relieved by rollercoasters.
Awarded to Lianne Parkin and her team at the University of Otago in New Zealand for demonstrating that people are less likely to slip over on icy footpaths if they wear their socks outside their shoes instead of inside.
For discovering the unusual sexual antics of the short-nosed fruit bat earned the award for Gareth Jones at Bristol University
A Raheny man has discovered a supernova (an exploding star). Dave Grennan, an amateur photography, was about to give up star gazing for the evening when he spotted the 290 million year old explosion using his powerful telescope. Mr Grennan is said to be "over the moon" after the most significant Irish astronomical discovery ever. The supernova has been given the uninspiring name Supernova 2010 IK and is said to be a type 1b supernova. They happen when a huge star shifts material to a smaller nearby star. Eventually the larger star becomes so unstable it blows up in a catastrophic explosion. These events are extremely rare and Mr Grennan was extremely lucky to be the first witness to such a fantastic event.

Frog Dissection is an excellent and very user-friendly iPad app that helps you learn more about the internal anatomy of the frog, without the need to actually dissect one! Frog Dissection allows you to dissect a mock chloroformed specimen complete with dissection instruments-pins, scalpel, marker, and forceps. The app provides step-by-step instructions for the dissection and incorporates some excellent 3D imaginery of the frog's internal organs. The app looks incredibly realistic and anatomincally acurate. There is also a section on frog classification and life-cycle, detail on organ function and anatomical comparisons of human body with the frog body explaining the similarities and differences between the two. Click here to visit their website for more information on the app. Definitely worth a purchase at only €3.99. Click here to visit the app store.
