Dewdrop-sized motes serve as invisible security guards A remarkable new invention from Tel Aviv University — a network of tiny sensors as small as dewdrops called "Smart Dew" — will foil even the most determined intruder. Scattered outdoors on rocks, fence posts and doorways, or indoors on the floor of a bank, the dewdrops are a completely new and cost-effective system for safeguarding and securing wide swathes of property. Prof. Yoram Shapira and his Tel Aviv University Faculty of Engineering team drew upon the space-age science of motes to develop the new security tool. Dozens, hundreds and even thousands of...

A new test can accurately detect Alzheimer's disease in its earliest stages, before dementia symptoms surface and widespread damage occurs, U.S. researchers said on Monday. The test, which measures proteins in spinal fluid that can point to Alzheimer's, was 87 percent accurate at predicting which patients with early memory problems and other symptoms of cognitive impairment would eventually be diagnosed with Alzheimer's, they said. "With this test, we can reliably detect and track the progression of Alzheimer's disease," said Leslie Shaw of the University of Pennsylvania School of Medicine, whose study appears in the Annals of Neurology. Such tests, which...

Author Reveals Its Origin and Meaning for St. Francis PADUA, Italy, JULY 22, 2005 (Zenit.org).- A major scholar on the Franciscans wrote a book on the meaning of the signature symbol of St. Francis of Assisi, the Tau. Order of Friars Minor Father Damien Vorreux, who died in 1998, explained in this posthumously published work that this letter, the last of the Hebrew alphabet, and the Omega in the Greek, was very well known at the time of St. Francis, and was already used by the Semites, Greeks and Latins. He heard, for example, Pope Innocent III open Lateran Council...

WASHINGTON (AP) -- While a breakthrough for humans could be years away, a new study in mice suggests some memory recovery may be possible in the early stages of Alzheimer's disease. "There basically are two prongs and we need to deal with both," said lead researcher Karen Ashe, a University of Minnesota neurologist. "What we're showing is that there are neurons which are affected (by Alzheimer's) but not dead." New research shows a mutant protein named tau is poisoning brain cells, and that blocking its production may allow some of those sick neurons to recover. It worked in demented mice...
