What is Functional epidemiology?

• Epidemiology is the foundation science of public health.
• Disease surveillance and epidemiology are two sides of the same coin; the former provides real-time information for action and the latter analyses data and facilitates planning.
• During the COVID-19 pandemic, lack of functional epidemiology led to inadequate forward planning.
• India has good epidemiologists, but they use their expertise predominantly for research and teaching — it is high time they used this discipline for managing public health.

What is Dark Matter?

Know about Dark Matter

• All interactions in the universe are a result of four fundamental forces acting on particles — strong nuclear force, weak nuclear force, electromagnetic force and gravitation.
• Dark matter is made up of particles that do not have a charge — which means they do not interact through electromagnetic interactions.
• So, these are particles that are “dark”, namely because they do not emit light, which is an electromagnetic phenomenon, and “matter” because they possess mass like normal matter and hence interact through gravity.
• Gravitational force, besides not being fully integrated and understood by particle physicists, is extremely weak. For one thing, a particle that interacts so weakly becomes rather elusive to detect.
• This is because interactions from other known particles could drown out signals of dark matter particles.

How could scientists infer the presence of dark matter?

• Dark matter makes up around 85% of the matter in the known universe, but because it doesn’t interact with light it is practically invisible. Likewise, whatever the constituent particles of dark matter are, they don’t interact strongly with other matter either.
• In fact, the only way scientists can infer the presence of dark matter is via its gravitational influence which literally holds together most galaxies, preventing their constituent stars from flying apart as they spin.

What is the latest about Dark Matter?

The latest to hit the news in the field of dark matter is a dark matter detector experiment named LUX-ZEPLIN (LZ) in South Dakota in the U.S. As of today, this is the most sensitive dark matter detector in the world.
