Nanobiocomposite antimicrobial surface coatings based on carbon nanotubes

Life-threatening infectious diseases caused by antibiotic-resistant pathogens have been of great concern in both community and hospital settings. This increasing emergence of antibiotic-resistant strains of pathogens has necessitated the development of new antimicrobial surfaces and coatings. As antimicrobial surfaces have become popular in such areas as consumer products, public spaces such as schools and offices, and public transportation, the market for these coatings has quickly grown into a market worth hundreds of million of dollars. New work, by a team from Rensselaer Polytechnic Institute (RPI) has now combined the antimicrobial property of a cell lytic enzyme (lysostaphin) and the excellent properties of carbon nanotubes as an immobilization support in preparing nanocomposite paints that are highly effective against antibiotic-resistant strains of Staphylococcus aureus - methicillin-resistant Staphylococcus aureus (MRSA).

Singularity Summit 2010 | Gene Expression

The Singularity Summit is going to happen in about a month in San Francisco (August 14th-15th). Registration here. Yes, Ray Kurzweil will be there, but also Irene Pepperberg, James Randi and John Tooby. If you want to meet the ladies, probably not your scene (perhaps more accurately the lady, or two). But if you want to high five Robin Hanson at an after hours meet-up, get ready to party!

Here are my reflections from last year.

Spiral Island Rises Again

bottleislandOver the last several years I have wrote about Spiral Island, Reishee Sowa’s private island constructed out of a quarter of a million used pop bottles. Unfortunately the island was destroyed by a hurricane in 2007 and was forced to start over from scratch.

Fast forward to the present and Reishee has become Rishi (and sometimes Richie) and his island has been reborn. His new island is a bit smaller, a modest 120,000 bottles, but he has “all the luxuries of home, including a private island for his ducks and a conch shell intercom system.”

On his website Rishi notes:

On his social networking website, Rishi tells us how his islands might benefit the world.

This old world economy is upsetting nature’s balance and polluting the air, so now carbon dioxide levels in the atmosphere are exponentially increasing as a seemingly ever growing world population using unecological industries continues to creep over the surface area of our gem of a planet and Mother Earth. We can actually help to balance this out and even reverse this process with floating islands. They can be all over the globe, on rivers, lakes and in protected oceans. They can provide sustainable habitats for plants, animals and humans can be even made on dry ground in potential flood areas such as Bangladesh. Peoples homes, gardens and lives can actually be saved instead of being washed away by the flood and if tethered the islands would even be in the same place after the flood subsided.
