Nobel Laureate finds 'elegant' explanation for DNA transcribing enzyme's high fidelity

...ornberg said. Yet the question of how the enzyme achieves such a high degree of discrimination between matched and mismatched NTPs remained unanswered. The chemical attraction alone between RNA bases—adenine, cytosine, guanine, and uracil—and their complementary bases on the DNA template strand is far fro...

Seals protect brain, conserve oxygen by turning off shivering response on icy dives

...se, a seal allows its body temperature to drop and achieves the benefits of hypothermia: a slower metabolism and lowered oxygen requirements which extends the dive time, Folkow said. Taking the plunge The seal experiment took place in a tank in which the seals took a series of experimental dives into ...

Interfering RNA silences genes in 'slippery' immune cells

...Children's Hospital of Philadelphia. "Our approach achieves results comparable to the conventional technique, which uses synthetic small interfering RNA but is very expensive and in short supply. We expect our technique to expand the toolbox for scientists doing research in immunology." RNA interference (RNA...

Predicting successful outcomes in living-donor liver transplants

... not be complete for donors, even though the liver achieves its full size within four weeks of transplant. "Whether the about 10 percent loss of function compared to preoperative values will translate into clinically relevant impairment of liver function ?in particular with respect to drug metabolism as sugge...

How does the brain know what the right hand is doing?

...entists have debated two options for how the brain achieves this: (1) the outflow hypothesis says that the brain monitors signals it sends to the muscles telling them how strongly to contract, and uses this to predict where the limb has moved to; (2) the inflow hypothesis suggests that the brain relies on in...

Intelligently designed molecular evolution

...romiscuous enzymes until an evolutionary path that achieves a desired result is found. The amino acid substitutions that significantly drive molecular evolution are called "plasticity residues." The Berkeley researchers identified the plasticity residues for the Grand fir sesquiterpene synthase, then syste...

NIH launches comprehensive effort to explore cancer genomics

...have clear milestones and goals. Only if the pilot achieves its goals will the full-scale project to develop a complete atlas of the cancer genome move forward. The Cancer Genome Characterization Centers, Genome Sequencing Centers, and Biospecimen Core Resources will be selected in 2006. Applications and pr...

Harnessing microbes, one by one, to build a better nanoworld

...etection system. The system detects more genes and achieves more than a 10-fold increase in sensitivity while using less sample for the detection of genes expressed at very low levels compared with conventional fluorescent microarrays. The system uses a chemiluminescence-detection instrument, software, and ch...
