The Venus Zone
September 17, 2014
Earth and Venus share a number of striking similarities, so why is one planet a bastion for life while the other is inhospitable. Are the planets' differences solely due to their relative distances to the sun? Planets found outside our solar system may provide new evidence to answer that question.

May 30, 2012
Refrigerators and air conditioners are so common these days that many people never stop to wonder: how do we make things cold? Today on the physics buzz podcast we'll talk about some of the clever ways that physics keeps us cool.
Physics of the Inversion
January 18, 2012
This time of year some areas of the world, including Salt Lake City Utah, experience an inversion, where cold air gets stuck on the ground underneath a layer of warm air. But doesn't cold air sink and warm air rise? Why is this the exception and not the rule? Learn why the consequences could be dire if it was.

More Volcanoes = Less Storms
December 06, 2010
Atmospheric scientists are studying the connection between volcanic eruptions in the tropics and their effect on hurricane activity. Eruptions produce ash that blocks sunlight, which cools the Earth's surface and oceans. Since hurricanes need warm ocean waters to form, there is an observed decrease in the number of storms after these eruptions.

Firefighting with Fog
January 01, 2006
Firefighters usually don't aim hydrants at smoke, to avoid producing steam that can come back and burn them. But smoke sometimes contains dangerous, flammable gases. Some U.S. fire departments are now experimenting with brief bursts of water on the hot gasses, to cool them down and reduce the risk of explosion. Since it was adopted in Sweden, the technique has cut firefighter fatalities in half.
Frostless Heat Pump
February 01, 2005
A new invention, the "frostless" heat pump, produces warmer air than a conventional heat pump by raising the temperature on the device's outer coils. This prevents frost on the coils while heat is suctioned more efficiently into the home.
Underwater Weather Watchers
January 01, 2005
Researchers are now collecting valuable information about ocean weather from a fleet of cost-effective instruments called Argo floats. Using hydraulic fluid in internal and external sacs, each float sinks about a mile and a half underwater. Every ten days, the float rises to the surface and transmits information on the ocean temperature and salt content. Researchers hope Argo will improve the ability to forecast the paths of hurricanes and where they will make their landfall.
