Smooth or grainy? New paper reviews research on the grain of space-time
2013-12-22
Smooth" or grainy? Is space-time continuous or is it made up of very fine (10-35 metres on the "Planck scale") but discrete grains, if we look at it very close up ? If the latter were true, scientists think, this would lead to deviations from the theory of special relativity formulated by Albert Einstein more than 100 years ago.
How Old is the Universe?
2013-12-22
Age may only be a number, but when it comes to the age of the universe, it's a pretty important one. According to research, the universe is approximately 13.8 billion years old. How did scientists determine how many candles to put on the universe's birthday cake? They can determine the age of the universe using two different methods: by studying the oldest objects within the universe and measuring how fast it is expanding.

Ancient Tributes to the Winter Solstice
2013-12-22
This weekend marks the beginning of the end. Of winter's darkness, that is. Today (Dec. 21), the Northern Hemisphere celebrates the mark of increasingly longer days, while the Southern Hemisphere will transition to shorter days, and those at the equator won't notice much of a difference at all.The global discrepancy in seasonal sunlight results from Earth's 23.5-degree tilt on its axis: During the Northern Hemisphere winter, the Earth is tilted directly away from the sun, and during the summer, it is tilted directly toward the sun. The equator does not experience much of a change during the year since it sits in the middle of the axis.

Banana Fungus Creeps Closer to World’s Key Plantations
2013-12-14
A variant of a fungus that rots and kills the main variety of export banana has been found in plantations in Mozambique and Jordan, raising fears that it could spread to major producers and decimate supplies. The pathogen, which was until now limited to parts of Asia and a region of Australia, has a particularly devastating effect on the popular Cavendish cultivar, which accounts for almost all of the multibillion-dollar banana export trade. Expansion of the disease worldwide could be disastrous, say researchers.
Abandoned mine could yield clues to stopping global warming
2013-12-14
An abandoned mine in California is providing scientists with important data that could lead to a possible new weapon to fight global warming.Massive amounts of the greenhouse gas carbon dioxide vacuumed from smokestacks or the air could be permanently locked up in a type of tight, magnesium-rich rock found in the mine, according to scientists. One tricky part is to break up the rock to make room for the greenhouse gas. And that may require violence.
