Reactive Reports Apr/May 2005 David Bradley	At Last, the Structure of DNA Researchers have made a significant advance in our understanding of life's main molecule, using X-ray crystallography to determine the three-dimensional structures of nearly all the possible sequences of a macromolecule.
Technology Research News May 4, 2005 Eric Smalley	Chip Gauges Cell Reactions Researchers have devised a way to test within minutes the reactions of cells to all types of stimuli. The researchers' system is very sensitive, relatively inexpensive, uses little power, and is portable.
Technology Research News May 4, 2005	Nano Pyramids Boost Fuel Cells Researchers have devised a way to make iridium surfaces that are extremely finely textured. The surface is textured with pyramids which increases the available surface area of the metal. The increased surface area speeds the catalytic reaction that breaks down ammonia to extract hydrogen.
Technology Research News April 20, 2005	Nanotube Chemical Sensor Gains Speed Researchers have made single-walled carbon nanotube chemical sensors that transmit information by measuring the charge in the nanotubes' capacitance, or ability to store electric charge.
Technology Research News April 6, 2005 Kimberly Patch	Programmed DNA Forms Fractal A researcher has showed that it is possible to coax short strands of artificial DNA to spontaneously assemble into a Sierpinski triangle. The ability is a step toward embedding programming instructions in chemical processes.
Technology Research News April 6, 2005	Strained Material Cleans up Memory Researchers have found a way to make a promising type of flash computer memory that does not contain environmentally toxic lead.
Reactive Reports March 2005 David Bradley	Fuel Cells US scientists have demonstrated a significant boost to fuel cells that could also cut costs. By coating the cathode with a thin layer of platinum instead of using solid metal, efficiency is raised by ten percent and the use of expensive platinum can be reduced.
Reactive Reports March 2005 David Bradley	Losing the Sulfur Dutch researchers have figured out why the activity of catalysts used to produce clean fuels gradually falls. Their findings show that loss of sulfur atoms from the catalyst itself is to blame and could lead to a way to remedy the situation.
Reactive Reports March 2005 David Bradley	Microbial Manufacturing A bacterium is a microscopic chemical factory producing antibiotics, immunosuppressants, and anticancer drugs no chemist can synthesize. but pharmaceutical companies have been tapping into microbial drug manufacturing for some time.
Reactive Reports March 2005 David Bradley	Lighting-up Time for Porphyrin Nanotubes Researchers have constructed nanotubes from nature's light traps, the porphyrins, to make a system that will use sunlight to split water in a process closely related to photosynthesis, potentially enabling a solar hydrogen-based economy.
