Hox genes control many features like segment morphology, appendage number(Arthropods) and pattern,axial morphology and limb pattern (vertebrates) ,which played significant role in modifications to their respective body plans during evolution.The morphological and functional evolution of appendages has played a …

Chromosome mis-segregation during female meiosis is the leading cause of miscarriages and birth defects in humans. Recent evidence suggests that these meiotic errors may be downstream of defects in oocyte growth and/or the hormonal signaling pathways that drive oocyte differentiation. Drosophila oogenesis provides a genetically tractable system to examine how the cell …

Everyone deserves a clean and safe environment in their homes but toxins formed in newly constructed and tightly packed buildings due to New paint, carpets, furniture etc. can lead to so called “sick building syndrome”.Growing plants in your indoors can be a real boon in these circumstances as they help in cleaning the air and also has ability to decompose toxins. Selecting plants with large leaves and mixing plant species in order to combat full range of toxins is recommended.
NASA-researcher, Dr. B.C. Wolerton introduced the idea of using plants as …

The rise of animals is an exceptional book and a must for all fossil lovers.It describes the life of animals that lived in precambrian era ,time when life was just beginning to unfold its diversity and led to animals with enormous body plan diversity during cambrian explosion.Written by palaeontologists describing their huge effort put in digging earth crust and searching rocks in remotest of places around the world in order to get an idea of how ancient world looked like.The stroy they narrate, photographs displayed will leave an everlasting impression …
