‘Leap second’ syncronises Indian time with Earth’s spin on January 1,2017

The atomic clock was programmed to add an extra second to 2017 to compensate for a slowdown in the Earth’s rotation.
A ‘leap second’ was added to the Indian clock at 5:29.59 hours on January 1 to synchronise with the Earth’s rotational clock. 
  • As the atomic clock at the National Physical Laboratory (NPL) here struck 23:59:59 last night, it was programmed to add an extra second to 2017 to compensate for a slowdown in the Earth’s rotation.

Drug discovery for GPCR signalling made easy by IIT Kanpur

Researchers have shown that the regulation of G Protein-Coupled Receptors (GPCRs) by new drugs can be simpler than generally thought — it can be mediated by engaging only the end of the receptor, which is called the tail of the receptor.

Significance of these findings:
With this, discovering new drugs that bind to G Protein-Coupled Receptors (GPCRs), which are central to almost every physiological process in our body such as vision, taste, immune response and cardiovascular regulation, becomes easier.

Fossil fuel formation linked to rise in atmosphere’s oxygen

The rapid rise in the atmospheres oxygen roughly 500 million years ago which made advanced animal life possible on Earth is linked to the process that led to the formation of fossil fuels, suggests new research.
According to the study, the rise in oxygen was associated with a rapid increase in the burial of sediment containing large amounts of carbon-rich organic matter – the raw material of coal, oil and natural gas.
