Detective DNA by Parvinder Chawla
The technology of DNA profiling is infallible, as it unerringly reveals the
identity of any organism from just a tiny body specimen. Commonly called DNA
fingerprinting, it is widely popular in parentage testing and forensic
identification, as it involves the analysis of the 'blueprint' for establishing
a person's unique molecular identity.Not just that. The causative bug of several
infec-tious diseases can be now detected with utmost precision. Ill-fated genes
responsible for many crippling and fatal genetic disorders can be predetermined
before they spell disaster. Any alteration in the blueprint causing these
disorders can be identified. Early diagnosis of a genetic disorder, even in an
unborn child, is possible today.This lucidly written and profusely illustrated
book, targeted at laymen explains with utmost clarity the so-phisticated modern
biotechniques involved in DNA profiling and its wide range of applications.
This ushering in of a new era of diagnostics owes its tribute to none other but
the key molecular investigator of DNA profiling, the modern day Sherlock Holmes .

The Formation of the Solar System: Theories Old and New by Michael Woolfson
This book traces the development of ideas about the origin of the Solar System
from ancient times to the present day. A survey of more modern ideas, covering
the last 200 years or so, highlights the difficulties experienced by theories
and also points the way towards the development of a more successful theory.
In particular, the current standard model the Solar Nebula Theory is examined
and discussed in some detail. After more than thirty years of development, this
theory has still not settled down into an agreed form, as it experiences both
theoretical difficulties and problems with reconciling new observations.
By contrast, the Capture Theory, developed over the last forty years by the
author, and supported by recent observations provides a complete description of
the formation of the Solar System, including an evolutionary hypothesis that
explains the detailed structure of the system. Written in an informative yet
accessible manner, this book will appeal to both specialist and non-specialist
readers alike.
