Single Molecule Is In Driver's Seat Of Molecular Machine
The downsides of conventional molecular machines are that they are driven as an ensemble, by external light or chemistry, for example, and they are big -- made up of many molecules. These factors make these machines difficult to control. In a recent theoretical paper, two Northwestern University chemists have shown how molecular machines can be driven individually by applying an electric current that creates an internal energy source. Signal That Switches On Eye Development Discovered -- Could Lead To 'E
Researchers have uncovered a crucial signal that switches on eye development. This discovery will greatly assist researchers looking at stem cells connected to eye development and opens up an avenue of research that could eventually lead to an 'eye in a dish.' Songs for Ice Cream TrucksServes Novelties for the Ears
One Ring Zero's Michael Hearst writes music to sound good coming out of the Good Humor man's truck. Now the songs, studded with sonic oddities, are catching on. Arthritis: Copper Bracelets, Magnetic Wrist Straps Useless? Trial Rais
Copper bracelets and magnetic wrist straps are ineffective in relieving arthritis pain, according to a new study. Researchers conducted the first randomized placebo-controlled trial on the use of both copper bracelets and magnetic wrist straps for pain management in osteoarthritis -- the most common form of the condition. [Ironic] Professional beggars prowling about the streets of Moroccan c
The government plans to crack down on the scam used by faux beggars in growing numbers for a kind of "emotional blackmail", a cabinet minister was quoted as saying... Neuroscientists Identify How Trauma Triggers Long-lasting Memories In
A research team led by UC Irvine neuroscientists has identified how the brain processes and stores emotional experiences as long-term memories. The research, performed on rats, could help neuroscientists better understand why emotionally arousing events are remembered over longer periods than emotionally neutral events, and may ultimately find application in treatments for conditions such as post-traumatic stress disorder. The Roman Curia: Congregations: Congregation for the Doctrine of the F
Information from the Vatican about this group "founded in 1542 by Pope Paul III ... [which] was originally called the Sacred Congregation of the Universal Inquisition as its duty was to defend the Church from heresy. It is the oldest of the Curia's nine congregations."Includes a brief profile, doctrinal and disciplinary documents, and related material, some of which are by Cardinal Joseph Ratzinger (now Pope Benedict XVI). Many of the documents are available in several languages (some not in English). PET/CT Can Identify New Cancer Lesions At Early Stage, Allowing For Pr
A team of researchers at Johns Hopkins Medical Institutions in Baltimore, Md., reports that whole-body positron emission tomography/computed tomography (PET/CT) scans may help physicians identify new, unexpected malignant cancerous tumors in patients, according to an article in the May issue of the Society of Nuclear Medicine's Journal of Nuclear Medicine. Compound In Wine Reduces Levels Of Alzheimer's Disease-causing Peptide
A study published in the November 11 issue of the Journal of Biological Chemistry shows that resveratrol, a compound found in grapes and red wine, lowers the levels of the amyloid-beta peptides which cause the telltale senile plaques of Alzheimer's disease. New Earthquake Model For Los Angeles Finds Some Faults Moving Faster T
An analysis of slip rates for 26 active faults in the Los Angeles metropolitan area validates a new approach to modeling fault tectonics and finds that some faults may be moving faster than earlier models estimated, University of Massachusetts Amherst scientists report.
