DNA Molecules Used To Assemble Nanoparticles

...o to three months per synthesis, and a significant loss of yield for each step, that approach just wouldn't be practical. Instead, the Baker group will create a library of single-functional dendrimers that can be synthesized in parallel, rather than sequentially, and then linked together in many differen...

...duction of Hox11."We know that if you have a major loss of blood, the spleen is turnedon to supplement the bone marrow in replenishing your blood supply. Wemay find that the spleen kicks in to help with many more biologicalemergencies. What has been considered a practically unnecessary organmay actually p...

It's not all genetic: Common epigenetic problem doubles cancer risk in mice

Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer

...its metabolism," says Loftus, citing the protist's loss of some genes and its apparent gain of other bacterial-like genes through lateral transfer. "This study will provoke interest in what secrets may lie undiscovered in the sequences of other supposedly 'simple' amoeba genomes." Named for its effective...

Bound for destruction: Ubiquitination protects against improper Notch signaling

Why do insects stop 'breathing'? To avoid damage from too much oxygen, say researchers

...are (1) such discontinuous breathing reduces water loss and (2) it enables insects to rid their bodies of carbon dioxide, respiration's byproduct, when the insects are underground. As is true for miners, insects, while underground, are faced with high-carbon-dioxide and low-oxygen amounts, necessitating a...

TEL2 gene cooperates with MYC gene to provoke B-cell lymphomas
