Battery life decreases during in the cold.
Some studies suggest 20-40% reduction, although in modern batteries this is only temporary. This is due the the atoms (or ions in the case of batteries) randomly moving at a slower pace. We must thus impart them with more energy to make them move. A representation is trying to get something over a hill. We need to impart force to get them is, and after the crest of the hill they can “travel” the rest themselves. Thus the crest represents a threshold which must …

This week we’re in Christmas mood and looking at the Science of the carious aspects of Christmas and Santa Claus. We will attempt to answer the following:
-How can Santa get down the chimney?
-How is Rudolf’s nose red?
-The logistics behind the day itself.
-How can reindeer fly?

Recent studies into the FTO gene have revealed variants of this gene may be linked to higher body mass index and obesity. The research suggests the FTO gene is active in the area of the brain which regulates food intake, the hypothalamus, and is involved in either regulating metabolism or DNA repair. However variants of the gene cause these processes to break down and may result in changes nutrient intake and energy expenditure.
According to the study one in six people of European decent carry two copies of the variant and compared to people with no copies of the gene had a 70% risk of obesity and could be an average of 3kg heavier.

ScienceNews reports that a new type of dinosaur, Limusaurus inextricabilis, has been discovered at a fossil dig site in China. The find is especially exciting due to the dinosaur’s apparent close relation to birds, further proving some scientists’ theory that one group of dinosaurs actually evolved instead of dying out. This group of dinosaurs, called theropods, walked on two legs, and the new dinosaur fossils that was discovered in China extend the link between theropods and modern day birds because of its clear similarity to bird hand-bone arrangements.

nbelievable video, you can see the poor guy’s (Anthony Van Loo of Roeselare) body jolt @ 0.16 secs in. This device literally saved the man’s life, numerous examples have happened in the past with tragic consequences. Mohamed Abdelwahab (Egypt), and the most famous example possibly being Marc Vivien Foe, who died while playing he Confederation’s Cup for Cameroon.

Interesting little article from the Danish Jylland’s Posten site on how Novo Nordisk, the Danish world leader in diabetes care, partook in the Saddam Hussain Oil-for-Food scheme run when the dictator was in power. The organisation’s head denied the whole thing in 2005: “I would like to inform the Danish public and the UN, that we we expose to this negative press.”

Just saw this on RTE news, amazing story. Connie Culp, 46, was shot in the face by her husband in 2004 - he then turned the gun on himself. 30 operations later, she still did not have the ability to perform ‘ordinary’ facial functions. A 22 hr operation, led by 11 surgeons has reHer news conference afterwards was special too, kids used to call her a monster. Connie used to have to carry a photo of herself to show them what she used to look like. It will be very interesting to see if she regains the ability to smell and drink (not using a straw) - things we all take for granted.

The knuckleball is an intriguing prospect from the outset. How can something which is sometimes not even thrown at 70mph compare to something thrown at 95+ mph by some fireballers (Jonathan Papelbon, Joba Chmberlain et al)??
Having experienced Tim Wakefield pitch live twice, it really is hilarious. The ball looks like it floats out of his hand towards large burly major leaguers. To see them swing violently and miss at something so slow is amazing. Which begs the question, what is the Science behind the knuckleball? As alluded to in the Ronaldo post, the principles isolated in this pitch are quite similar. The distinct lack of spin imparted to Wakefield’s pitch and Ronaldo’s strike results in the respective balls making erratic movements on the way to their targets due to increased drag, results in the goalkeeper and hitter, respectively, having trouble anticipating where the object ball will be on arrival.
