Mice that lack CatSper have sex just as often as normal mice. The mutant males, however, are infertile...
...hearing testimony on bioterrorist threats, rattled lawmakers launched an investigation into U.S. preparedness. They found two drugs were considered feasible treatments for anthrax: Penicillin and doxycycline. And they found problems with both. Scientists fear that introducing massive amounts of penicillin into the general population could hasten the creation of mutant penicillin-resistant strains of bacteria. Likewise, there was some evidence that terrorists had engineered strains of the anthrax bacteria resistant to both penicillin and doxycylcines. There was another option, lawmakers were told: Cipro...
Working with Mallinckrodt Professor of Chemistry and Chemical Biology George M. Whitesides, Collier bound multiple copies of the protein to a flexible backbone. The connected proteins block the toxin’s entrance into the cell. Separately, Collier has constructed a mutant protein that actually integrates itself into the pore that the toxin enters, blocking its action...
...everything goes well, he says, the mutant protein might yield human therapies in a couple of years...
...same time, however, we must be careful not to allow doomsday prophecies and other scare-mongering to provoke extreme reactions. Stockpiling huge quantities of vaccines or antibiotics may be expensive and ultimately ineffective, especially in an age when mutant germs and antibiotic-resistant microbes can be easily developed. Instead, investing in intelligence missions, research and the public health infrastructure should provide more value and security in the long...
