Melting icebergs are doing their own bit to halt the onward march of global warming. By releasing iron into the Southern Oceans, melting icebergs are fuelling the growth of plankton - which help to remove a substantial amount of CO2 from the atmosphere.
University of Pittsburgh researchers have developed the first natural, nontoxic method for biodegrading carbon nanotubes, a finding that could help diminish the environmental and health concerns that mar the otherwise bright prospects of the super-strong materials commonly used in products, from electronics to plastics.
The Nordic Institute for Theoretical Physics announced the Nordita research program and symposium on 'Theoretical Assessment of the Biological Effects of Nanomaterials'. The event will take place from March 6-28, 2009, in Stockholm, Sweden.
The 2008 Foresight Institute Feynman Prizes, named in honor of pioneer physicist Richard Feynman, are given in two categories, one for experimental work and the other for theory in advances in nanotechnology.
The Nanotechnology Knowledge Transfer Network (NanoKTN), one of the UK's primary knowledge-based networks for Micro and Nanotechnologies, has announced that their first Nano 4 Life event will take place on Wednesday 11th February hosted by The Wellcome Trust in London.
The summit is a highly efficient forum for varied stakeholders from solar, wind, biomass, IT, transport, construction, aviation, nanotechnology and biotechnology to bring together the business and science of the most important and relevant Green Energy and Clean technologies.
The technology involves a unique surface engineering process that adds micro and nano sized hair like structures to the surface which creates a ?living interface? between artificial implants and bone. The addition of a multilayer coating containing biological substances, such as growth factors and antibiotics, could improve bony integration, arterial and venous proliferation and reduce infection.
In a new tactic in the fight against cancer, Cornell researcher Michael King has developed what he calls a lethal 'lint brush' for the blood - a tiny, implantable device that captures and kills cancer cells in the bloodstream before they spread through the body.
A team of Cornell researchers has invented an efficient, inexpensive method to electrically characterize individual carbon nanotubes, even when they are of slightly different shapes and sizes and are networked together.
Researchers at The Scripps Research Institute have solved one of biology's neatest little tricks: they have discovered how a cell's outer membrane pinches a little pouch from itself to bring molecules outside the cell inside - without making holes that leak fluid from either side of the membrane.
At today's IEEE International Electron Devices Meeting, IMEC presented a monolithically integrated 11-megapixel micro-mirror array for high-end industrial applications - a world's first both in terms of pixel density and reliability
A microscopic biological sensor that detects Salmonella bacteria in lab tests has been developed by an Agricultural Research Service (ARS) scientist and university colleagues. The sensor could be adapted to detect other foodborne pathogens as well.
