| Engineered bacteria mop up mercury spills Posted: 11 Aug 2011 05:15 PM PDT Thousands of tons of toxic mercury are released into the environment every year. Much of this collects in sediment where it is converted into toxic methyl mercury, and enters the food chain ending up in the fish we eat. New research showcases genetically engineered bacteria which are not only able to withstand high levels of mercury but are also able to mop up mercury from their surroundings.  |
| Researchers decode workings of mysterious, but critical TB drug Posted: 11 Aug 2011 12:13 PM PDT A new study suggests that PZA binds to a specific protein named RpsA and inhibits trans-translation, a process that enables the TB bacteria to survive under stressful conditions.  |
| Scientists discover how molecular motors go into 'energy save mode' Posted: 11 Aug 2011 12:13 PM PDT The transport system inside living cells is a well-oiled machine with tiny protein motors hauling vital cargo around the cell. A new study describes how the motors save energy, when their transport services aren't required. The solution to this molecular puzzle provides new insight into how molecular motor proteins are regulated, and may open new avenues for the treatment of various neurodegenerative diseases, such as Alzheimer's and Huntington's.  |
| Hidden soil fungus, now revealed, is in a class all its own Posted: 11 Aug 2011 11:28 AM PDT A type of fungus that's been lurking underground for millions of years, previously known to science only through its DNA, has been cultured, photographed, named and assigned a place on the tree of life.  |
| Route for eliciting HIV-neutralizing antibodies mapped Posted: 11 Aug 2011 11:28 AM PDT Researchers have traced in detail how certain powerful HIV neutralizing antibodies evolve, a finding that generates vital clues to guide the design of a preventive HIV vaccine, according to a new study.  |
| Scientists copy the ways viruses deliver genes Posted: 11 Aug 2011 06:48 AM PDT Scientists have mimicked the ways viruses infect human cells and deliver their genetic material. The research hopes to apply the approach to gene therapy -- a therapeutic strategy to correct defective genes such as those that cause cancer.  |
