India's New Missile, Satellite Tech, Pollution Impacts, and More
This news covers several science and technology topics.
The Pralay missile is a new weapon developed in India.
The NISAR satellite uses special radars to see through clouds and forests to take pictures of Earth.
Air pollution like the stuff from cars and power plants can make it more likely for people to get dementia.
Earthquakes start deep underground at a spot called the hypocenter.
Finally, ham radios are used by hobbyists and for emergencies to talk to each other around the world.
The Pralay missile is an indigenously developed solid propellant quasi-ballistic missile capable of carrying multiple warheads.
NISAR uses L-band and S-band radars that can penetrate clouds and vegetation to provide detailed Earth imagery.
PM2.5, Nitrogen dioxide, and soot are air pollutants linked to an increased risk of dementia.
The hypocenter is the location below the Earth's surface where an earthquake originates.
Ham radio is used for educational and informational purposes, allowing communication between licensed operators.

Study Finds Link Between Air Pollution and Dementia
Research suggests that long-term exposure to air pollutants, specifically PM2.5, nitrogen dioxide, and soot, increases the risk of dementia. This study is based on a review of numerous other studies, providing statistical evidence of the link.
The Specific Findings of this Research
The risk of dementia jumped by a specific percentage for each pollutant. The risk can vary, and studies may not always reflect causation.
