Breast CT Scanner Could Improve Cancer Screen Comfort
... looking to be more effective than traditional mammography at detecting breast masses.
More work needs to be done to find microcalcifications, tiny specks
of calcium which don't always mean cancer is present but bear checking, he added.
Next, Boone hopes to use the breast CT scanner to guide intervent...
Stardust Brings Interstellar Dust
... see lots of impacts. There are big ones, there are small ones’, he said.
According to Brownlee, there might be more than a million microscopic specks
of dust embedded in Stardust's Aerogel collector. He said that Aerogel was a remarkable material that is as much as 99.9% empty space, and it greatly ...
Early Detection Of Breast Cancer
.../ It identifies calcifications in the breast that appear only as tiny white specks
on mammography film. These tiny white specks
could be early cancers.
Researchers reviewed the cases of 519 patients ...
Monkeys offer genetic clues to adult blindness
...e-related macular degeneration develops when a small, light-detecting part of the retina called the macula breaks down. The disease causes nodule-like specks
to build up in the eye, chipping away central vision over time.
But Dawson said most people don't even realise something is wrong until they det...
Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer
They're but a tiny speck, existing in a variety of forms: particles, tubes, shells, even a soccerball-like shape. They also share a common prefix: "nano," connoting their size, a billionth of a meter or roughly 25-millionth of an inch.
Today, cancer researchers are exploring the potential of suc...
American Chemical Society's weekly PressPac -- March 11, 2009
... describes a new, highly sensitive dating method, called accelerator mass spectrometry, that requires only 0.05 milligrams of carbon (the weight of 50 specks
of dust). That's much less than the several grams of carbon needed with radiocarbon dating.
The research included analyzing pictographs from numero...
Leatherback turtles' newly discovered migration route may be roadmap to salvation
...erhaps the tremendous water clarity may work to the advantage of these leatherbacks because they are visual predators," he said. "They can spot little specks
of white out in the deep blue sea." Leatherbacks dine exclusively on gelatinous zooplankton, such as jellyfish.
Shillinger also said that there is ...
How did chemical constituents essential to life arise on primitive Earth?
... the vast distance between the smaller molecules required to form adenine in outer space precludes its formation, unless some nucleation centers, like specks
of interstellar dust, are present.
Numerous experiments have demonstrated that amino acids, nucleotides, carbohydrates and other essential compound...
Rice scientists unveil 'nanoegg'
... the "nanoegg," the latest addition to their family ultrasmall, light-focusing particles. A cousin of the versatile nanoshell, nanoeggs are asymmetric specks
of matter whose striking optical properties can be harnessed for molecular imaging, medical diagnostics, chemical sensing and more.
Nanoeggs are de...
