Features
		Sinks for Anthropogenic Carbon
		We have learned much about the workings of natural sinks like the oceans and terrestrial plants, but are just beginning to understand how their behavior might change as atmospheric CO2 concentrations rise -- Jorge L. Sarmiento and Nicolas Gruber
		Superconducting Magnets above 20 Tesla
		Superconductors are key components of magnets that generate homogeneous, low-noise, and extremely stable high fields. Further increasing the strength of these fields will require meeting a number of technological challenges -- Steven W. Van Sciver and Kenneth R. Marken
		The Early History of Quantum Tunneling
		Molecular spectra, electron emission from metals, and alpha decay provided fertile ground in the 1920s for applying the new ideas of quantum mechanics -- Eugen Merzbacher

		Observing the Cosmic Microwave Background at High Resolution Bolsters the Inflationary Big Bang Scenario
		The angular resolution of the new Cosmic Background Imager is fine enough to reveal, for the first time, the primordial seeds of galaxy clusters.
		Choreographing Wave Propagation in Excitable Media
		Excitable media can be coaxed into complex spatiotemporal patterns, including spiral waves and oscillating tiger stripes.
	Issues & Events
		Science and Technology Are a Focus of Debate on New Homeland Security Department
		Congress, the administration, and a National Research Council committee have come up with myriad ideas for creating a department of homeland security, but just what role science and technology will play is unclear.
		Components of 'Little Boy' Sold at Auction
		The original red arming plug and green safety plug that were built for Little Boy, the first of only two atomic bombs ever used in combat, have been sold at auction for $167 000.
		European Space Science Stretches Lean Budget
		To save its science missions, ESA will follow a more rigid schedule and forge closer cooperation with national space agencies.
		New Criteria for Determining Interagency R&D Budgets
		Since the early days of the Bush administration, OMB officials have warned that tighter rules for funding interagency R&D programs were on the way. The rules have arrived, and they cover applied and basic research.
		Recipe for LHC Success: Subtract Other Science, Add Accountability
		CERN has begun implementing accounting and organizational changes and is slashing programs that do not directly support the Large Hadron Collider.
		Synchrotron Partners Take Steps to Open SESAME
		Even as violence escalates in the Middle East, plans for SESAME, a synchrotron light source intended to use science to promote peace in the region, are moving forward.
		Lo to Lead NRAO
		Fred Lo has been tapped for the top job at the National Radio Astronomy Observatory, according to a 20 June announcement by Associated Universities Inc, which runs NRAO for NSF.
		Totsuka Tapped as KEK Chief
		Yoji Totsuka will take the reins for a three-year term as director general of the High Energy Accelerator Research Organization (KEK) in Japan.
