Breakthrough gene-editing tool can find and replace DNA better than CRISPR

-
"Prime editing" is more precise and more efficient than CRISPR and could herald a new era of genetic manipulation.
The ability to edit the genes of human beings by changing the code of life -- DNA -- has dramatically improved over the last decade. Current tools, like CRISPR-Cas9and base editors, are extremely powerful but have traditionally suffered from a lack of precision, high error rate and limited scope, hampering their ability to treat human genetic disease. A breakthrough gene-editing tool, developed by a team of researchers at Harvard University and unveiled Monday, has the ability to make extremely precise DNA edits, ushering in a new era of genetic manipulation.

"In many respects this first report is the beginning rather than the end of a longstanding aspiration ... to be able to make any DNA change in any position of a living cell or organism including, potentially, human patients with genetic diseases," says David Liu, a chemist at Harvard's Broad Institute and co-author of the new study.

Sequence Analysis is still sexy:Dual Descriptor Method for Biological Sequence Analysis

-
The emergence of “Systems Biology” in recent years highlights the systematic viewpoint of bio-system modeling. Building on such a background, Dual Descriptor Method, a generic methodology for biological sequence analysis is proposed. From a systematic perspective, Dual Descriptor is defined as a two element set of Composition Weight Map and Position Weight Function which aim at reflecting the composition and permutation information of a sequence. An alternate training algorithm is provided to get an optimum description of the building patterns of the sequences. In this paper , dual descriptor method has been applied to the analysis of two typical problems of molecular biology: gene identification and the prediction of protein function. Satisfactory and insightful results are achieved. Owing to the generality of this methodology, dual descriptor method has wide application perspective for many problems of pattern recognition, especially those involved in “Systems Biology”.

Abbott Laboratories Buys Piramal Healthcare Limited Biz for $3.72B

-
Abbott May 21 announced a definitive agreement with Piramal Healthcare Limited to acquire full ownership of Piramal's Healthcare Solutions business (Domestic Formulations), a leader in the Indian branded generics market, for an up-front payment of $2.12 billion , plus $400 million annually for the next four years, giving Abbott the No. 1 position in the Indian pharmaceutical market. This further accelerates Abbott's emerging markets growth following the recent acquisition of Solvay Pharmaceuticals and announcements last week of Abbott's collaboration with Zydus Cadila as well as the creation of a new stand-alone Established Products Division to focus on expanding the global markets for its leading branded generics portfolio. "This strategic action will advance Abbott into the leading market position in India , one of the world's most attractive and rapidly growing markets," said Miles D. White , chairman and chief executive officer, Abbott. &quo
