The Next Big Thing Is Small: Nanotechnology Could Lead To Radical Impr
When it comes to taking the next "giant leap"in space exploration, NASA is thinking small -- really small. In laboratories around the country, NASA is supporting the burgeoning science of nanotechnology. The basic idea is to learn to deal with matter at the atomic scale -- to be able to control individual atoms and molecules well enough to design molecule-size machines, advanced electronics and "smart"materials. 'Silent' Nighttime Acid Reflux Symptoms Can Cause Poor Sleep And Sleep
New research on acid reflux shows: 1. Patients with sleep complaints but no heartburn symptoms suffered episodes of nighttime acid reflux; 2. Symptoms of gastroesophageal reflux are common and frequently severe in patients with obstructive sleep apnea. Video How-To: Chat With an Integrated Webcam
Everyone's used to chatting via phone or IM, but video chatting is a little more tricky. Here's how to make your webcam chats picture perfect.
 Carotid Stenting The New Anti-depressant?
Inserting a stent to open a narrowed carotid artery has been found to reduce symptoms of depression that may be associated with carotid stenosis, according to a study in the August issue of Radiology. Tracing Marijuana To Its Roots: Scientists Seek Marijuana's Isotopic F
Scientists at the Alaska Stable Isotope Facility can tell whether marijuana confiscated in a traffic stop in Fairbanks likely came from Mexico or the Matanuska Valley. They're also working on a way to determine whether it was grown indoors or out. A few more years and enough samples and they hope to have something even more precise: an elemental fingerprint that could tell police where and under what conditions a sample of marijuana was grown. Lands Surface Change On Alaska Tundra Creating Longer, Warmer Summers
A gradual lengthening of the snow-free season in Alaska's tundra, and a corresponding northward progression of the growth of shrubs and trees, may be creating a cycle of warmer and longer summers in the Alaskan Arctic according to a new study to be published in the Sept. 22, 2005, issue of Science Express. Immune System Finding Paves Way For Vaccine Use In Some Leukemia, Lymp
Researchers at The University of Texas M. D. Anderson Cancer Center and the National Cancer Institute have found that an experimental vaccine can prime the immune system to help fight an aggressive form of lymphoma, even though prior therapy had eliminated virtually all of the B cells thought necessary to mount such a defense. How Can We Make Nanoscale Capacitors Even Smaller?
Researchers at UC Santa Barbara have discovered what limits our ability to reduce the size of capacitors, often the largest components in integrated circuits, down to the nanoscale. They have answered a 45-year-old question: Why is the capacitance in thin--film capacitors so much smaller than expected? Parkinson’s Researchers Focus On Chemical From Soil Bacteria
A chemical produced by common soil bacteria may kill neurons that produce dopamine, according to a new study. Dopamine neuron demise leads to the hallmark symptoms of Parkinson's disease, a movement disorder affecting some 1 million Americans. Researchers Help Sort Out The Carbon Nanotube Problem
National Institute of Standards and Technology (NIST) and university researchers report a significant step toward sorting out the nanotube "problem"--the challenge of overcoming processing obstacles so that the remarkable properties of the tiny cylindrical structures can be exploited in new polymer composite materials of exceptional strength.
