A giant space rock demolished an ancient Middle Eastern city and everyone in it – possibly inspiring the Biblical story of Sodom

As the inhabitants of an ancient Middle Eastern city now called Tall el-Hammam went about their daily business one day about 3,600 years ago, they had no idea an unseen icy space rock was speeding toward them at about 38,000 mph (61,000 kph). This article mentions the meteorite impact calculator developed by Purdue EAPS.

EAPS undergrad received hands-on experience at ACRE with DURI internship

Purdue University offered many opportunities for students to get involved with research. One such opportunity is the Discovery Park Undergraduate Research Internship Program (DURI) . Purdue University senior Matthew Graber, an Atmospheric and Chemistry student, accepted a DURI internship this summer to work with field characterization of agricultural aerosols at Purdue’s Agronomy Center for Research and Education (ACRE).

Would we still have severe thunderstorms over North America if the Gulf of Mexico were filled in with land?

The eastern United States is a hot spot for severe thunderstorms. Researchers from Purdue University say the reason is much more closely tied to the terrain of North America, rather than the presence of the Gulf of Mexico.

The Science of Wet Bulb Temperature

Nearly 50 million Americans are under heat alerts as hot and humid weather grips the Midwest and south central U.S. But it's not just the number on the thermometer that counts.
