Washing fresh fruits and vegetables before eating may reduce the risk of food poisoning and those awful episodes of vomiting and diarrhea. But washing alone -- even with chlorine disinfectants -- may not be enough, according to a new study.
Bikini Corals Recover From Atomic Blast, Although Some Species Missing

Half a century after the last earth-shattering atomic blast shook the Pacific atoll of Bikini, the corals are flourishing again. Some coral species, however, appear to be locally extinct. One of the most interesting aspects is that the team dived into the vast Bravo Crater left in 1954 by the most powerful American atom bomb ever exploded (15 megatons - a thousand times more powerful than the Hiroshima bomb). The Bravo bomb vaporised three islands, raised water temperatures to 55,000 degrees, shook islands 200 kilometers away and left a crater 2km wide and 73m deep.
Are Sacrificial Bacteria Altruistic Or Just Unlucky?

An investigation of processes accompanying spore formation in the bacteria B. subtilis shows that chance plays a significant role in determining which of the microbes sacrifice themselves for the colony and which go on to form spores. The results, which appear in Molecular Systems Biology, highlight the degree to which individual bacteria can deviate from population-wide norms.
Mouse Study Can Illuminate How Tumors Manipulate The Human Vascular System

Tumors use the body's blood system for their own purposes: They stimulate the growth of blood vessels that supply the tumor. Medical treatment blocks this process in order to restrain tumors. Scientists have now developed a method for producing a complex human vascular system in mice.
Community-based Approach Best Bet To Control Free-roaming Cats, Survey Suggests
16:47 18-04-2008; source: www.sciencedaily.com
A survey gauging Ohioans' attitudes about free-roaming cats suggests that no single statewide measure would be sufficient in managing cat overpopulation because public opinion about outdoor cats varies widely across the state. In particular, perceptions about the need to regulate cat overpopulation in Ohio tend to differ among rural and urban dwellers and among cat owners and people who do not own pets. Compounding the problem is that a quarter of Ohio households are feeding free-roaming cats, but most of those residents aren't ensuring that the outdoor cats they feed are spayed or neutered.
World's Oldest Living Tree -- 9550 years old -- Discovered In Sweden

The world's oldest recorded tree is a 9,550 year old spruce in the Dalarna province of Sweden. The spruce tree has shown to be a tenacious survivor that has endured by growing between erect trees and smaller bushes in pace with the dramatic climate changes over time.

Quotes:
I am no more humble than my talents require.
The test of our progress is not whether we add more to the abundance of those who have much; it is whether we provide enough for those who have too little.
Of course, our failures are a consequence of many factors, but possibly one of the most important is the fact that society operates on the theory that specialization is the key to success, not realizing that specialization precludes comprehensive thinking
