A man received 217 COVID shots — what does his body teach us?

Posted on By admin

The COVID-19 pandemic has been a roller-coaster for vaccinology — from a rare show of truly global collaboration between governments, multilateral agencies, the scientific community, and industry to huge public demand for rapid vaccine development against the new virus that had brought the world to its knees to sudden concerns of “too rapid” development when…

Why it matters that scientists modified a ‘sexual’ fruit fly to be asexual

Posted on By admin

The fruit-fly (Drosophila melanogaster) has been among the favourite organisms of genetics researchers for more than a hundred years. Many years of intense research with these diminutive creatures have led to many breakthroughs in our understanding of biology and evolution. Recently, researchers from Cambridge University and the California Institute of Technology reported yet another such…

Are many Labradors hard-wired for obesity?

Posted on By admin

New research finds around a quarter of Labrador retriever dogs face a double-whammy of feeling hungry all the time and burning fewer calories due to a genetic mutation. This obesity-driving combination means that dog owners must be particularly strict with feeding and exercising their Labradors to keep them slim. The mutation is in a gene (POMC), which…

Why India urgently needs a legal framework for genomics

Posted on By admin

The last two decades have seen unprecedented advances in genomics. These advancements have come in the background of our ability to sequence, analyse and interpret genomes at an unprecedented scale, along with an emerging and expanding corpus of evidence to act upon the genomic information for healthcare decision making. As the costs of sequencing continue to…
