Treatment appropriate for some patients who are not good surgical candidates

A minimally invasive, experimental treatment is proving successful in removing small kidney tumors from appropriate patients, report researchers from Massachusetts General Hospital (MGH). In a study in the February 2003 issue of Radiology, the MGH team describes how a technique called radiofrequency ablation (RFA) destroyed all renal cell carcinoma (RCC) tumors less than 3 cm in size and some larger tumors, d

A study led by a Duke University scientist suggests that the current emphasis on controlling upstream nitrogen pollution fails to adequately address the impacts on water quality of another potential contaminant, phosphorus. Thus, according to the scientists, current strategies used by environmental managers to control excessive nutrients in coastal wetlands may not achieve their intended goals.

The finding was published in a report in the Friday, Jan. 24, 2003, issue of the journal Science b

Using the same technology that creates tiny, precisely organized computer chips, a Johns Hopkins research team has developed beds of thousands of independently moveable silicone “microneedles” to reveal the force exerted by smooth muscle cells.

Each needle tip in the gadget, whose development and testing is reported this week in the advance online edition of the Proceedings of the National Academy of Sciences, can be painted with proteins cells tend to grab onto. By measuring how far a contr

Jefferson Lab is once again taking center stage, as Lab scientists, engineers and technicians mobilize to provide 81 niobium cavities for 23 cryomodules for the Spallation Neutron Source under construction in Oak Ridge, Tennessee

Thermos bottles usually don’t weigh nearly five tons or measure almost 26 feet end-to-end. But these aren’t run-of-the-mill containers for soup or coffee. Rather, they’re the complex, state-of-the-art supercooled components in which particle beams are

An experiment conducted by the Department of Energy’s Jefferson Lab generates THz radiation 20,000 times brighter than anyone else; breakthrough lights way for application development

Experiment generates THz radiation 20,000 times brighter than anyone else; breakthrough lights way for application development

An experiment conducted with Jefferson Lab’s Free-Electron Laser has shown how to make a highly useful form of light — called terahertz radiation — 20,000 times brigh

Jefferson Lab’s Free-Electron Laser used to explore the fundamental science of how and why nanotubes form, paying close attention to the atomic and molecular details

Scientists and technologists of all stripes are working intensively to explore the possibilities of an extremely strong and versatile cylinder so tiny that millions — which in bunches look like an ebony snowflake — could fit easily on the tip of a pin. The objects in question are known as carbon nanotubes, first discov
