In 1967, Simon Kochen and Ernst Specker proved mathematically that even for a single quantum object, where entanglement is not possible, the values that you obtain when you measure its properties depend on the context. So the value of property A, say, depends on whether you chose to measure it with property B, or with property C. In other words, there is no reality independent of the choice of measurement. It wasn't until 2008, however, that Alexander Klyachko of Bilkent University in Ankara, Turkey, and colleagues devised a feasible test for this prediction. They calculated that if you repeatedly measured five different pairs of properties of a quantum particle that was in a superposition of three states, the results would differ for the quantum system compared with a classical system with hidden variables. That's because quantum properties are not fixed, but vary depending on the choice of measurements, which skews the statistics. "This was a very clever idea," says Anton Zeilinger of the Institute for Quantum Optics, Quantum Nanophysics and Quantum Information in Vienna, Austria. "The question was how to realise this in an experiment." Now he, Radek Lapkiewicz and colleagues have realised the idea experimentally. They used photons, each in a superposition in which they simultaneously took three paths. Then they repeated a sequence of five pairs of measurements on various properties of the photons, such as their polarisations, tens of thousands of times. A beautiful experiment They found that the resulting statistics could only be explained if the combination of properties that was tested was affecting the value of the property being measured. "There is no sense in assuming that what we do not measure about a system has [an independent] reality," Zeilinger concludes.

The organic molecules found by the team also have chlorine atoms, and include chlorobenzene and several dichloroalkanes, such as dichloroethane, dichloropropane and dichlorobutane. Chlorobenzene is the most abundant with concentrations between 150 and 300 parts-per-billion. Chlorobenzene is not a naturally occurring compound on Earth. It is used in the manufacturing process for pesticides (insecticide DDT), herbicides, adhesives, paints and rubber. Dichloropropane is used as an industrial solvent to make paint strippers, varnishes and furniture finish removers, and is classified as a carcinogen.

Synote makes multimedia resources such as video and audio easier to access, search, manage, and exploit. Learners, teachers and other users can create notes, bookmarks, tags, links, images and text captions synchronised to any part of a recording, such as a lecture. Imagine how difficult it would be to use a textbook if it had no contents page, index or page numbers. Synote actually provides the way to find or associate notes with a particular part of a recording,i.e. the media fragments.

Earth observation data have increased considerably over the last decades with satellite sensors collecting and transmitting back to Earth several terabytes of data per day. This data acquisition rate is a major challenge to existing data management, exploitation and dissemination approaches used by various agencies such as ESA, NASA and European national space agencies. To make the available petabytes of EO data easily accessible by an even larger group of end user applications, TELEIOS will design and implement a Virtual Earth Observatory by building on the following state of the art technologies:

"The results are published in Nature Medicine today. Co-author Stanley Hazen, head of cardiovascular medicine at the Cleveland Clinic in Ohio, says that the study could signal a new approach to diet and health. In some cases, an individual's collection of intestinal microbes may be as important to their diet as anything on a nutrition label, he says. "Bacteria make a whole slew of molecules from food," he says, "and those molecules can have a huge effect on our metabolic processes.""

"Similarly, how should cancer biologists think about cancer cells capable of producing vascular endothelial growth factor, a protein that promotes the growth of blood vessels? Clearly, the importance of this protein only makes sense when thinking about a cancer cell's environment: how close it is to blood vessels that it can exploit, for example."

"According to the US Centers for Disease Control and Prevention's website: "Ricin works by getting inside the cells of a person's body and preventing the cells from making the proteins they need. Without the proteins, cells die... Death from ricin poisoning could take place within 36 to 72 hours of exposure, depending on the route of exposure (inhalation, ingestion, or injection) and the dose received."
