The new method has enabled the researchers to get a higher proportion of a given dose of medication into the tumor cells than is possible with the 'free' drug—that is, the one not bound to nanotubes—thus reducing the amount of medication that they need to inject into a subject to achieve the desired therapeutic effect.

Nanotechnology has provided numerous constructs that reduce oxidative damage in engineering applications with great efficiency. As a new research report shows, nanotechnology applications could also help to remediate radioactive contamination at the source, by removing radioactive ions from the environment.

Many vulnerable species are facing reduced numbers because the adaptations that have served them for thousands of years make them unable to survive small changes in temperature or precipitation. When faced with climate change and other threats to their habitat, some species may not be able to relocate quickly enough to save them from extinction. A new technique called assisted colonization may prove to be an innovative solution.

Access and benefit sharing means that one person or entity (the user) obtains biological or genetic resources and or knowledge from another person, entity, or country (the provider) in exchange for benefits. The Convention on Biological Diversity (CBD) aims to achieve the fair and equitable sharing of benefits arising out of the use of genetic resources and associated traditional knowledge by facilitating access through prior informed consent of the provider. All the countries in the Himalayan more...
