Chemical Engineer Kao Explores Antibiotic Synthesis With DNA Chips

...ck of cards, and inducing a beneficial mutation as slipping in a joker. It's easy to see which decks have jokers--or which strains produce more antibiotics. Imagine mixing and then separating ten decks that all have two jokers each. Do it with enough replications and you'll get a deck with 20 jokers--or a bac...

...l defined targets. Getting it right may avoid your slipping or twisting an ankle. "This visual guidance mechanism could also help gymnasts on the beam, or acrobat walkers on a tightrope, as in these situations accurate foot placement becomes crucial," says Reynolds. ...

Scientists unveil piece of HIV protein that may be key to AIDS vaccine development

... impenetrable sugar cloak prevents antibodies from slipping in and blocking the proteins the virus uses to latch onto a cell and infect it. In 1998, Dr. Kwong and colleagues published the first X-ray snapshot of the core of HIV gp120 as it attaches to a cellular receptor known as CD4. That image gave re...

Danish researches solve virus puzzle

...onger the pseudoknot the more often this backwards slipping happens. The different protein formed is the protein needed by the virus, with possible serious consequences for the hosting organism. This is the manner in which many vira, e.g. HIV, trick the cell into producing something which it never would have ...
