Top 10 scientific breakthroughs of 2013

Washington, December 21: The annual list of groundbreaking scientific achievements, selected by Science and its international nonprofit publisher, has been revealed.

The top most breakthrough has been cancer immunotherapy, followed by a gene-editing technique called CRISPR, which is used to manipulate the genomes of various plant, animal and human cells.

The list compiled by Science and American Association for the Advancement of Science includes solar-cell materials which are cheaper and easier to produce than those in traditional silicon cells, and the techniques involving the use of the structure of an antibody to design an immunogen, which is a powerful tool for fighting diseases.

The imaging technique called CLARITY, which renders brain tissue transparent and puts neurons on full display, also made it to the list.

Also, the study which suggested that the brain cleans itself much more efficiently during sleep as well as stem cells derived from cloned human embryos, made it to the list. (ANI)
