Every Second Counts
Geophysicists have
identified the very real
physical mechanism that can
lengthen or shorten the
amount of time the earth
takes to complete one
rotation. During La Nina the
temperature of the Pacific

Harder Rain, More Snow
While raising average global
temperatures, climate change
could also bring more snow,
harder rain, or heat waves,
meteorologists say. Computer
models based on climate data
from nine countries indicate
every place on the plan ... > full story
Predicting When Tornadoes Will Strike
Meteorologists found
connections between the sea
surface temperature in the
tropical Pacific Ocean and
the occurrence of tornadoes
in unlikely parts of the
North American continent.

Home Runs & Hole-in-One
Two mathematicians at the
University of Northern
Colorado are taking a fresh
statistical look at the
effects of elevation on
hitting -- specifically at
Coors Field in Denver, where

Geophysicists Discover Slippery Secret Of Weaker Underwater Earthquakes
Seismologists investigating undersea earthquakes have found that molten rock lubricates faults. This decreases the amount of friction between sides of the fault and decreases the intensity of ... > more -
Are Bioluminescent Bacteria Behind Milky Seas Legend?
For centuries, sailors in the Indian Ocean have told stories of seas glowing with a dim, white light at night. Satellite images have now confirmed the appearance of what seem to be bioluminescent ... > more -
Geophysicists Show That Crust Temperature Variation Explains Half Of Elevation Differences In North America
Geophysicists determined that tectonic mountain-building processes are not the only factor that determines elevation in North America. The temperature of the crust affects its density, and lower ... > more -
Acoustical Oceanographers Record Noises in the Deep
Manmade and natural sounds, from boat engines to rainfall, sound different below the sea surface. To study their impact of noise on marine life, scientists are submerging devices called Passive ... > more -
Physicist Calls for Airline Industry to Educate Workers about Radiation Levels
At the high altitudes and latitudes commercial airlines fly, crews are subjected to higher-than-normal radiation levels from the sun and cosmic rays. Physicist Robert Barish believes airline crew ... > more -
Mechanical And Aerospace Engineers Use Satellites To Track Ozone Levels
Engineers processed data from NASA's Aura satellite in order to track and predict the movement of airborne pollution. Using satellite data to measure ozone concentrations over time allows scientists ... > more -
Environmental Engineers Detect Turbines' Turbulence Effects
Wind farms may have an impact on local weather patterns. As environmental engineers have discovered, wind farm propellers create a lot of turbulence in their wake, mixing air up and down with effects ... > more -
Meteorologists Are Getting Better at Forecasting
The U.S. experiences more severe storms than any other country in the world. Recent improvements in forecasting technology -- especially in computer simulations have brought five-day weather ... > more -
Earth Scientists And Geographers Integrate Maps And Weather Data
Scientists created a way to combine weather data and geographic information systems software in a visual display for use in disaster response. They created a map with a variety of ways to layer and ... > more -
Oceanographers Uncover The Physics Of Rip Currents
Rip currents flow in very erratic patterns, not in steady courses as previously believed -- which may help explain why they can be so dangerous even for experienced swimmers. Oceanographers have ... > more
