Maelstrom Quashes Jumping Genes
Scientists have known for
decades that genes called
transposons can jump around
the genome in a cell. This
jumping can be dangerous,
especially when it arises in
cells that produce eggs and

Researchers Solve Structure Of An Enzyme Vital For DNA Repair
When dividing cells copy
their DNA, mistakes can --
and do -- occur. To
compensate, cells have a
built-in system to correct
these errors. That

How DNA Repairs Can Reshape Genome, Spawn New Species
Researchers have shown how
broken sections of
chromosomes can recombine to
change genomes and spawn new
species. The scientists used
X-rays to break yeast

Critical Protein Complex In Formation Of Cell Cilia Identified
August 19, 2008 — Scientists have identified a protein complex that regulates the formation of cilia, which are found on virtually all mature human cells and are essential to normal cell ... > full story -
How Daughter Is Different From Mother
August 18, 2008 — Scientists know how mother and daughter can be so different. Mother and daughter yeast cells, that is. The researchers have discovered a new mechanism for cell fate determination -- how one cell, the ... > full story -
White Blood Cell Uses DNA 'Catapult' To Fight Infection
August 14, 2008 — Scientists have made a breakthrough in understanding how a type of white blood cell called the eosinophil may help the body to fight bacterial infections in the digestive tract, according to new ... > full story -
Trapping White Blood Cells Proves Novel Strategy Against Chronic Viral Infections
August 14, 2008 — A drug that sequesters white blood cells in lymph nodes can allow mice to fight off a chronic infection by a virus that causes meningitis. The novel strategy of restricting white blood cells' ... > full story -
Using Live Fish, New Tool A Sentinel For Environmental Contamination
August 13, 2008 — Researchers have harnessed the sensitivity of days-old fish embryos to create a tool capable of detecting a range of harmful chemicals. By measuring rates of oxygen use in developing fish, which are ... > full story -
Single MicroRNA That Controls Blood Vessel Development Identified
August 13, 2008 — Scientists have identified a key regulatory factor that controls development of the human vascular system, the extensive network of arteries, veins and capillaries that allow blood to reach all ... > full story -
Egg P Bodies Protect Maternal Gene Messages
August 12, 2008 — A cell decides what proteins to make based on the messages it receives from its genome. Sometimes messages are held back to be read later, and in most cell types these delayed messages are stored and ... > full story -
Test To Protect Food Chain From Human Form Of Mad Cow Disease
August 12, 2008 — Scientists are reporting development of the first test for instantly detecting beef that has been contaminated with tissue from a cow's brain or spinal cord during slaughter -- an advance in ... > full story -
Positive-feedback System Ensures That Cells Divide
August 11, 2008 — In the life of every cell, there's a point of no return. Once it enters the cell cycle and passes a checkpoint known as "Start," a cell will follow the steps it needs to divide -- no matter what ... > full story -
Eroded Telomeres Are Behind A Rare Premature Aging Syndrome
August 11, 2008 — Each time a cell divides, the protective caps at the ends of chromosomes shorten -- and when these caps are gone, so are we. Now, by using an unconventional strategy to shorten telomeres in mice, ... > full story
