Surface features common in the northern and southern midlatitudes of Mars and known as lobate debris aprons and lineated valley fill are believed to have formed either as debris flows mobilized by pore ice or as debris-covered glaciers.

In the summer of 1968, Dave Kavanaugh set off on a hike that would change the course of his life. As a second-year medical student at the University of Colorado, he had joined a climbing club with a few members of the biophysics department, and the group had set their sights on Gray's Peak—the ninth highest mountain in Colorado.

Very cold ice films in laboratory reveal mysteries of universe

The AANS offers this advice for winter sports enthusuasts: Whether you are a novice or advanced, an average person or a celebrity – proceed with caution, and play it safe on the slopes and snow. Wearing a helmet and following other safety precautions may save your life or the life of your child.

Mars With Ice, Shaken, Not Stirred

harminka — Sat, 27 Oct 2007 14:28:16 -0500

Mars, like Earth, is a climate-fickle water planet. The main difference, of course, is that water on the frigid Red Planet is rarely liquid, preferring to spend almost all of its time traveling the world as a gas or churning up the surface as ice.

Hot Ice to Lubricate Artificial Joints

A recent simulation has shown that thin layers of ice could persist on specially treated diamond coatings at temperatures well above body temperature, which could make ice-coated-diamond films an ideal coating for artificial heart valves, joint replacements, and wear-resistant prosthetics.

Scientists say no large Northern Hemisphere ice sheets 41 million years ago

harminka — Thu, 23 Aug 2007 01:55:28 -0500

New research to test global ice volume approximately 41.6 million years ago shows that ice caps at this time, if they existed at all, would have been small and easily accommodated on Antarctica.
