Space Debris

David Wright
OpenURL
Show Topic
Controlling the production of debris is crucial to the sustainable use of space. But even without additional launches, let alone antisatellite tests, the amount of debris orbiting Earth will continue to increase far into the future.

Clathrate Hydrates Under Pressure

Wendy L. Mao, Carolyn A. Koh, and E. Dendy Sloan
OpenURL
Show Topic
Icy solids in Earth's permafrost and deep ocean basins store an enormous reservoir of natural gas. That reservoir, and scientists' efforts to synthesize related molecular‐storage compounds, may help solve our energy problems.

Frontiers of Surface Science

Gabor A. Somorjai and Jeong Y. Park
OpenURL
Show Topic
The field of surface physics is evolving to include molecular‐scale studies of nanoparticle surfaces, as well as single‐crystal surfaces in contact with liquids or high‐pressure gases.

Varying Cosmic‐Ray Flux May Explain Cycles of Biodiversity

Bertram Schwarzschild
OpenURL
Show Topic
The solar system oscillates through the Milky Way's midplane with a period of about 60 million years. That cyclic excursion might be causing periodic fivefold increases in Earth's exposure to extragalactic cosmic rays.

Ultrafast Laser Spectroscopy Measures Heat Flow Through Molecular Chains

Mark Wilson
OpenURL
Show Topic
Analysis of the time‐resolved disorder in hydrocarbon molecules indicates that heat propagates ballistically.

Statistical Physics is for the Birds

Toni Feder
OpenURL
Show Topic
Three‐dimensional mapping of starling flocks could shed light not only on the birds' collective behavior but also on a broad range of other aggregate systems.

Fermilab Forms Backup Plan to Avoid Science Gap

Toni Feder
OpenURL
Show Topic
High‐intensity beams of rare particles could give Fermilab a vibrant scientific program if delays in the International Linear Collider spell a dry period for the lab.
