Molecular Imposter Rebuts Long
Ever since Watson and Crick first cracked the structure of DNAin 1953, biochemists have speculated that hydrogenbonding between DNA's four bases plays a key role in the amazingaccuracy of this genetic blueprint. But new researchwith a molecular imposter is calling some of these long-heldbeli...Study Furthers Understanding Of Critical Alzheimer's Disease Gene
Researchers have cracked part of the code for an important gene function infamilial Alzheimer's disease (FAD), an early-onset type of AD. Alzheimer'sdisease is the most common cause of dementia. Working with cells in culturethat had been altered to overexpress the amyloid...Scientists Discover Important Molecular Link That Allows Cells To Form Blood Vessels

Device sounds off on cracks A cracked bolt may not faze Tim "The Tool Man" Taylor as he does home improvements, but it can debilitate an industrial or nuclear plant if undetected. A new inspection device developed at the Department of Energy's Pacific Northwest National Laboratory detec...Animals regulate their numbers by own population density
Zoologists from the University of Toronto have cracked the ecological puzzle of how animals - in this case the arctic ground squirrel - manage to control their own population in the northern boreal forest of Canada. In a study to be published in the Nov. 23 issue of Nature, the researchers found that whe...Science's Top 10: genome sequencing named top scientific advance of 2000

Since many researchers believe that water is essential for the existence of life, these discoveries have piqued interest in the possibility of f...Key step in gene activation discovered
Scientists have cracked the code of an essential signal in the sequence of steps that controls the molecular choreography of gene regulation. The discovery is expected to aid development of therapies and prevention strategies for certain genetically triggered diseases such...URI professor investigates the muscle behind blue mussels

Now a team of biologists and engineers has cracked the molecular secrets of the gecko's unsurpassed sticking power--opening the door for engineers to fabricate prototypes of synthetic gecko adhesive. "Two millennia later, we have solved the puzzle of how geckos use millions of tiny foot hairs to adh...Sequenced malaria genome exposes novel drug targets
The genetic code of the malaria parasite has been cracked and is already revealing novel drug targets that could lead to effective treatment of the disease. An international effort was launched in 1996 to sequence the genome of the most deadly malaria species, Plasmodium falciparum. Botanists from the Univ...Scientists decode mosquito/malaria parasite genomes
... week that international groups of scientists have cracked the genetic codes of two organisms implicated in malaria, one of the world's most serious infectious diseases. Researchers have completed the genomes of the one-celled malaria parasite, Plasmoidum falciparum, and the mosquito Anopheles gambiae, the m...Rutgers explorer describes sea floor hot springs as teeming with valuable minerals and microbes
...the earth's crust, most of it under the ocean, is cracked into plates that move and allow heat and materials from the earth's interior to escape. As result we know that most of the minerals on the sea floor probably come from sources under the sea floor."
