Weill Cornell Research Reveals Secrets Of Trafficking Within Cells

...ew method of inquiry. It combined two pre-existing technologies -- RNA interference (RNAi), where scientists cut down on protein expression by jamming the responsible gene with bits of RNA; and microscopy, which looks at the activity of individual living cells by attaching a fluorescent tag to a specific cell com...

The secret lives of whales

... were as much as ten times greater than today. New technologies that allow researchers to observe the deep-sea, now point to another unintended legacy of hunting whales ?the elimination of entire communities of deep-sea animals. Craig Smith, from the University of Hawaii, studies dead whales after they have sunk...

Learning to fight an adversary that won't stay down

New biomolecular technologies have largely failed to deliver the hoped-for knockout punch breakthrough against the defences of disease-causing bacteria, says a leading Canadian specialist in antibiotic resistance. Techniques such as genomic sequencing and high throughput screeni...

Imaging Lymph Nodes with Nanoparticles

...types of imaging, ranging from ultrasound to newer technologies such asmagnetic resonance imaging (MRI). All these methods have problems; someare very invasive, others are very time consuming, and none arecompletely reliable.However in one of the more exciting crossovers from chemistry intomedicine, researchers h...

Novel antiviral technology inhibits RSV infection in mice

...treatment combiningnanoparticle and gene silencing technologies thwarts attacks ofrespiratory syncytial virus (RSV) -- a virus associated with severebronchitis and asthma, an animal study by University of South Floridaresearchers found. The study was reported in the January 2005 issue ofthe journal Nature Medicin...

Key molecule in plant photo-protection identified

...tutions, he had acquired several keytechniques and technologies that allowed him to closely track changesin live brain cells in mice with an Alzheimer's-like condition.The mice he used for the study had two mutations. One, utilized byscientists at Eli Lilly, causes amyloid plaques to build up, creatingthe Alzheim...

W.M. Keck Foundation funds study of friendly microbes

...ays. "We are dedicated to integrating concepts and technologies from a variety of disciplines so that we can analyze the massive amounts of information encoded in genomes and experimentally test predictions about gene functions that come from our computer-assisted analyses." Gordon views the human gut as "a bior...
