Researchers reveal smoke particles from wildfires can erode ozone layer
Updated : 3 years ago IST
Smoke from a wildfire may travel to great heights and linger there for up to a year. The protective ozone layer that shields the Earth from the sun's harmful UV rays while suspended there may be eroded by these particles, revealed a recent MIT study.

Smoke particles from wildfires can erode ozone layer: Research
Updated : 3 years ago IST
A wildfire can send smoke into the stratosphere, where it can linger for up to a year. According to a new MIT study, these particles can cause chemical reactions that erode the protective ozone layer that protects the Earth from the sun's harmful ultraviolet radiation while suspended there.

Acids help against airborne viruses: Research
Updated : 3 years, 2 months ago IST
Viruses such as SARS-CoV-2, influenza virus and others travel from person to person essentially by hitchhiking on aerosols. These are finely dispersed particles containing liquid suspended in the air that an infected person expels when coughing, sneezing, or simply exhaling, and can be inhal

Carbon ultrafine particles accelerate lung cancer progression
Updated : 3 years, 3 months ago IST
While it may seem common knowledge that smoking is bad for your lungs, if and how ultrafine particles present in cigarette smoke impact the development and progression of lung cancer remains unclear. Working with animal models, researchers at Baylor College of Medicine sought to find how air
