| Amazing Maze Of Maize Evolution: Study On Maize Domestication May Help Improve Crop Yields
October 5, 2009 at 11:00 pm
|
| Understanding the evolution and domestication of maize is important for many researchers. As one of the most important crops worldwide and one that appears very different from its wild relatives because of domestication, understanding exactly how maize has evolved has many practical benefits and may help improve crop yields. Researchers recently compared corn kernel development to its closest wild relative and have overturned some commonly held beliefs on the domestication of maize. |

| Laser Scans To Confirm Nero's Return: 21st Century Scan Could Reveal Rare Sculpture Of 1st Century Roman Emperor
October 5, 2009 at 8:00 pm
|
| Experts working at the Fishbourne Roman Palace in the UK are preparing to scan the damaged statue of a boy's head to reveal if it is a rare depiction of Roman Emperor Nero as a youngster. They will run 3D scans on the head to recreate the damaged parts of the face. If their theories are correct, the marble head would be the third surviving piece of its kind in the world and particularly rare in Britain where all images of Nero were believed to have been completely destroyed following his suicide in AD68. |

| Telomere Copy Protection: Nobel Goes To Scientists Who Solved How Chromosome Ends Work
October 5, 2009 at 11:00 am
|
| This year's Nobel Prize in Physiology or Medicine is awarded to three scientists who have solved a major problem in biology: how the chromosomes can be copied in a complete way during cell divisions and how they are protected against degradation. The Nobel Laureates have shown that the solution is to be found in the ends of the chromosomes -- the telomeres -- and in an enzyme that forms them -- telomerase. |
