Pakistan tests 2,200-km range surface-to-surface missile

Pakistan on Jan 23 conducted the first flight test of long range surface-to-surface ballistic missile Ababeel. It claimed that the missile has the capability to carry nuclear warheads and engage multiple targets with high precision, defeating the enemy’s hostile radars.
About:
  • The missile has a maximum range of 2,200 Km. “The missile is capable of delivering multiple warheads, using Multiple Independent Re-entry Vehicle (MIRV) technology.

Guided Pinaka rocket successfully test fired

Pinaka rockets, with a guidance system and an enhanced range, were successfully test-fired from the Integrated Test Range (ITR) at Chandipur in Odisha.
Details:
  • The earlier Pinaka version, which was an unguided one, has now been transformed into a guided version, with a navigation, guidance and control kit developed by the Research Centre, Imarat (RCI), Hyderabad.

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.

ISRO drones help map disasters in north-east

ISRO starts landing tests for Chandrayaan-2 mission

The Indian Space Research Organsiation has started a series of ground and aerial tests linked to the critical Moon landing of Chandrayaan-2 in Karnataka.

Chandrayaan-1, India's first mission to moon

Chandrayaan-1, India's first mission to Moon, was launched successfully on October 22, 2008 from SDSC SHAR, Sriharikota. The spacecraft was orbiting around the Moon at a height of 100 km from the lunar surface for chemical, mineralogical and photo-geologic mapping of the Moon. The spacecraft carried 11 scientific instruments built in India, USA, UK, Germany, Sweden and Bulgaria.
