Tel Aviv, Israel -- A team of scientists says digging below the Dead Sea will extract material that could provide an important look at Earth's history over the past 500,000 years.
An international team of researchers has begun drilling from a platform near the Israeli Dead Sea resort of Ein Boqeq, Britain's Daily Telegraph reported Wednesday. A thin slice of Earth's history will be extracted from a 3,937-foot-deep borehole being drilled by a special rig set up in the northern basin of the sea.
Scientists will examine layers of sediment laid down during the course of millions of years beneath the lowest place on Earth, looking for clues about shifting weather patterns, seismic activity and climate change.

Tel Aviv, Israel -- Israeli researchers say they've developed a portable but powerful electronic bomb sensor that can detect multiple kinds of explosives better than any dog.
The new device is attracting considerable attention from security companies worldwide, ScienceDaily.com reported Thursday.
Developed by Tel Aviv University chemist Fernando Patolsky, the sensor improves on existing detection technologies that have the drawbacks of high cost, lengthy decoding times, size and a need for expert analyses.
"There is a need for a small, inexpensive, handheld instrument capable of detecting explosives quickly, reliably and efficiently," Patolsky says.

Tel Aviv, Israel -- Israeli researchers say the process of "cloud seeding" to encourage rainfall by dispersing chemicals into the clouds may not be as effective as long believed.
In a comprehensive reassessment of cloud-seeding efforts stretching back 50 years, scientists at Tel Aviv University say the practice of using materials such as silver iodide and frozen carbon dioxide is not an effective mechanism for increasing precipitation, a university release said Monday.
The researchers examined a half century of data on cloud seeding, focusing on the effects of seeding on rainfall amounts in a target area over the Sea of Galilee in the north of Israel.

Tel Aviv, Israel -- Israeli researchers say they're creating an "atlas" of human brain connections that may give insights into conditions such as autism and schizophrenia.
Yaniv Assaf of Tel Aviv University's Department of Neurobiology is investigating how different parts of the human brain "connect" to turn this information into a "brain atlas," a release from the university says.
Disorders like autism and schizophrenia are not localized, researchers say -- there is no one place in the brain they can be found.
Assaf hopes a brain atlas will help in understanding how parts of our brain connect to other parts within, leading to a deeper understanding of these diseases.

Tel Aviv, Israel -- Israeli scientists say they have developed a nanotechnology that can enable fiber optics to replace semiconductors in communications.
Tel Aviv University researchers led by Koby Scheuer of the university's NanoPhotonics Laboratory said the newly developed technology can make computers operate hundreds of times faster. He said the communications technology "enabler" might be in use within five to 10 years and can also result in smaller, more flexible and more powerful devices.

Tel Aviv, Israel -- Most water treatment plants use chlorine to keep water free of bacteria but Israeli scientists say ultraviolet light might be a better method.
Tel Aviv University postdoctoral researcher Hadas Mamane, doctoral student Anat Lakretz, Professor Eliora Ron and their team said although chlorine keeps water free of micro-organisms, it also produces carcinogenic byproducts.
The scientists say they recently determined the optimal UV wavelength water treatment plants and large-scale desalination facilities could use to destroy health-threatening micro-organisms, as well as make the facilities more efficient.

Haifa, Israel -- Israeli scientists say they've discovered bees prefer nectar with small amounts of nicotine and caffeine over nectar that does not include those substances.
"This could be an evolutionary development intended, as in humans, to make the bee addicted," said University of Haifa Professor Ido Izhaki, who led the study.
Flower nectar is primarily comprised of sugars, which provide energy for the potential pollinators, the scientists said. But they said the floral nectar of some plant species also includes small quantities of caffeine and nicotine. The study sought to determine whether those substances are intended to "entice" the bees or whether they are byproducts that are not necessarily linked to any such objective.

Tel Aviv, Israel -- A Tel Aviv District Court Monday convicted four people of assaulting two entertainment industry executives on behalf of the late entertainer Dudu Topaz.
Ynetnews.com said Topaz was arrested May 31 and subsequently confessed to orchestrating the attacks on Reshet and Keshet executives Avi Nir and Shira Margalit. Topaz committed suicide in his prison cell Aug. 20.
An indictment issued against him June 18 said Topaz had "resolved in his heart to take revenge on the senior media officials whom he blamed for the slump in his career."
Daniel Zanko was convicted on charges of assault and conspiring to commit a crime.

Tel Aviv, Israel -- Israeli scientists say they've created a nanomaterial that may revolutionize solar panels, batteries and even be used as the basis for self-cleaning windows.
Tel Aviv University Professor Ehud Gazit, graduate student Lihi Adler-Abramovich and colleagues said they have developed a method to control the atoms and molecules of peptides so that they "grow" to resemble small forests of grass. The "peptide forests" repel dust and water.
"This is beautiful and protean research," Adler-Abramovich said. "It began as an attempt to find a new cure for Alzheimer's disease. To our surprise, it also had implications for electric cars, solar energy and construction."

Tel Aviv, Israel -- Israeli scientists say the interval between the brain's registration of a visual stimulus and the conscious recognition of it is 1/3 to 1/2 second.
Tel Aviv University Professor Yair Bar-Haim and researchers Moti Salti and Dominique Lamy said they used electroencephalography to measure the brain activity of research participants as they were exposed to computer images of cubes that quickly flashed on and off. They asked the study participants whether they had seen the stimulus and to report its location on the computer screen.
The scientists said the EEG data showed conscious awareness of the visual stimulus occurred 300 to 400 milliseconds after exposure to the stimulus.
