About Yellow band Disease

• Yellow-band disease—named for the colour it turns corals before destroying them—was first spotted decades ago and has caused widespread damage to reefs in the Caribbean. 
• There is no known cure for this disease and unlike coral, bleaching corals will not be restored once they get infected by this disease.
• Scientists believe overfishing, pollution and rising water temperatures because of climate change may be making the reefs more vulnerable to yellow-band disease.

• During the 1980s, the area saw numerous earthquakes - minor enough to avoid large damage but big enough for local buildings to develop cracks. 
• Following these quakes, the Dutch government had earlier said that it would shutter the field in response to local protests.

• Such extraction causes rocks to contract - as the pores get to hold fewer and fewer hydrocarbons over time.

About Bimodal nuclear propulsion 

• Bimodal nuclear propulsion is a two-part system that includes; Nuclear Thermal and Nuclear Electric Propulsion (NTP /NEP).
• It uses a wave rotor topping cycle. 

How will nuclear propulsion work?

• The Nuclear Thermal system includes a nuclear reactor that will heat liquid hydrogen (LH2) propellant and turn it into ionised hydrogen gas (plasma) that will then be channelled through a nozzle to generate thrust.
• Nuclear Electric Propulsion depends on a nuclear reactor to provide electricity to a Hall-Effect thruster (ion engine), which will generate an electromagnetic field that will ionise and accelerate an inert gas to create thrust.
• Advantages: Fuel efficiency, a higher specific impulse, rating and unlimited energy density.
