Devising Nano Vision For An Optical Microscope
Contrary to conventional wisdom, technology's advance into the vanishingly small realm of molecules and atoms may not be out of sight for the venerable optical microscope, after all. In fact, research at the National Institute of Standards and Technology (NIST) suggests that a hybrid version of the optical microscope might be able to image and measure features smaller than 10 nanometers--a tiny fraction of the wavelength of visible light. In A Technical Tour De Force, Scientists Take A Global View Of The Epi
A collaboration between researchers at the Salk Institute for Biological Studies and the University of California at Los Angeles captured the genome-wide DNA methylation pattern of the plant Arabidopsis thaliana - the "laboratory rat"of the plant world - in one big sweep. "In a single experiment we recapitulated 20 years worth of anecdotal findings and then some,"says senior author Joseph Ecker, Ph.D., a professor in the Salk Institute's Plant Biology Laboratory. Sudden Loss Of T Cells Is Not Trigger For AIDS, New Study Suggests
A sudden loss of T cells -- white blood cells crucial to the immune system -- is not the trigger for the onset of AIDS, according to a new study. The study challenges current thinking regarding AIDS, namely that a sudden, acute loss of T-cells is considered to be sufficient to predict progression to the disease's last stages -- final collapse of the immune system and death.

This is "a five-year effort to understand the human journey —where we came from and how we got to where we live today."It will "map humanity's genetic journey through the ages."The site includes a project overview, a FAQ, genetics overview and glossary, and an interactive atlas of the human journey. Includes images and video clips. From the National Geographic Society. Hubble Spies Shells Of Sparkling Stars Around Quasar
New images reveal the wild side of an elliptical galaxy nearly two billion light-years away, that previously had been considered mild-mannered. Hubble photos show shells of stars around a bright quasar, known as MC2 1635+119, which dominates the center of the galaxy. The presence of the shells is an indication of a titanic clash with another galaxy in the relatively recent past. Research Sheds Light On How Cancer Cells Become Resistant To Treatment
A new study by researchers at Memorial Sloan-Kettering Cancer Center and The Johns Hopkins University provides new insight into how tumor cells can become resistant to anti-cancer therapy.
