With the help of a tech-savvy 3-D model of atmospheric chemistry with a high spatial resolution that analyzed pollution globally and found clues leading to its impact on human health, a recent joint study by universities discovered that one in five deaths from 2018 ― that is, 8.7 million ― was caused by fossil fuel air pollution.
Microscopic, and sometimes larger, particles of soot, smoke and dust that spew out of gas-guzzling factories, ships, cars and aircraft are responsible for 18 percent of total global deaths in 2018 that equals more than 8 million people, a new study found.

A startup company founded by applied physicists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) intends to transform consumer electronics by introducing a powerful technology for imaging and illumination that could replace conventional lenses with an ultrathin, flat optical microchip.

Superspreading events have distinguished the COVID-19 pandemic from the early outbreak of the disease. Now, research from Harvard University, Tulane University, MIT and Massachusetts General Hospital finds that a critical factor in these and other transmission events is the propensity of certain individuals to exhale large numbers of small respiratory droplets. The researchers found that age, obesity and COVID-19 infection all correlate with a propensity to breathe out more respiratory droplets.
Understanding the source and variance of respiratory droplet generation may lead to effective approaches to reducing COVID-19 infection and transmission.
“Respiratory droplet generation in the airways varies between people depending on their phenotype,” said David Edwards, Associate in Bioengineering at the Harvard John A. Paulson School of Engineering and Applied Sciences and co-author of the study. “While our results show that the young and healthy te
