(PhysOrg.com) -- Scientists and curiosity seekers who want to know what a partially or completely cloaked object would look like in real life can now get their wish -- virtually. A team of researchers at the Karlsruhe Institute of Technology in Germany has created a new visualization tool that can render a room containing such an object, showing the visual effects of such a cloaking mechanism and its imperfections. http://www.physorg.com/news177268469.html Physics Fri, 13 Nov 2009 15:00:19 EST news177268469 (PhysOrg.com) -- In the series Star Trek, Klingons and Romulans have spaceships outfitted with cloaking devices that hide their presence from sight, as well as from the sensors of their rivals' spaceships. Unlike current invisibility cloaks, which are mostly effective only over a narrow range, these fictional devices provide a broadband type of invisibility that so far has eluded modern scientists. http://www.physorg.com/news171876586.html Physics Fri, 11 Sep 2009 10:00:01 EST news171876586 The speed of light, 300 million metres per second, was long thought an immutable constant and has defined our understanding of matter and energy but recent research in the area of optics and photonics is proving that we can manipulate light to some ingenious and hugely lucrative ends. http://www.physorg.com/news171694289.html Physics Wed, 09 Sep 2009 05:55:38 EST news171694289 (PhysOrg.com) -- University of Utah mathematicians developed a new cloaking method, and it's unlikely to lead to invisibility cloaks like those used by Harry Potter or Romulan spaceships in "Star Trek." Instead, the new method someday might shield submarines from sonar, planes from radar, buildings from earthquakes, and oil rigs and coastal structures from tsunamis. http://www.physorg.com/news169703752.html Physics Mon, 17 Aug 2009 04:56:57 EST news169703752 Using a composite metamaterial to deliver a complex set of instructions to a beam of light, Boston College physicists have created a device to guide electromagnetic waves around objects such as the corner of a building or the profile of the eastern seaboard. http://www.physorg.com/news168263666.html Physics Fri, 31 Jul 2009 12:55:25 EST news168263666 Two new studies reveal a way to increase the body's appetite for gobbling up the cancer stem cells responsible for acute myeloid leukemia (AML), a form of cancer with a particularly poor survival rate. The key is targeting a protein on the surface of those cells that sends a "don't eat me" signal to the macrophage immune cells that serve as a first line of defense, according to the reports in the July 24th issue of the journal Cell. http://www.physorg.com/news167571471.html Medicine & Health Thu, 23 Jul 2009 13:00:04 EST news167571471 (PhysOrg.com) -- Research at the University of Liverpool has shown it is possible to develop an 'invisibility cloak' to protect buildings from earthquakes. http://www.physorg.com/news167304857.html Physics Mon, 20 Jul 2009 10:34:50 EST news167304857 (PhysOrg.com) -- Science fiction and fantasy tales are full of the ability to "cloak" characters with invisibility. Whether it is a spaceship with a cloaking device, or a young wizard with an invisibility cloak, the interest in rendering someone or something invisible captures our fancy. Scientists have succeeded in creating the illusion of invisibility by bending light around a region for concealment. These types of devices have limitations, however; one of these limitation that the device normally has to be touching the object to be rendered invisible - or in very close proximity. http://www.physorg.com/news166350509.html Physics Thu, 09 Jul 2009 10:00:02 EST news166350509 A group of researchers from the Department of Physics at UAB (Universitat Autonoma de Barcelona, Spain) have designed a device, called a dc metamaterial, which makes objects invisible under certain light - very low frequency electromagnetic waves - by making the inside of the magnetic field zero but not altering the exterior field. The device, which up to date has only been studied in theoretical works, thus acts as an invisibility cloak, making the object completely undetectable to these waves. http://www.physorg.com/news166184064.html Physics Tue, 07 Jul 2009 11:15:00 EST news166184064 (PhysOrg.com) -- The great science fiction writer Arthur C. Clarke famously noted the similarities between advanced technology and magic. This summer on the big screen, the young wizard Harry Potter will once again don his magic invisibility cloak and disappear. Meanwhile, researchers with Berkeley Lab and the University of California Berkeley will be studying an invisibility cloak of their own that also hides objects from view. http://www.physorg.com/news160409033.html Physics Fri, 01 May 2009 15:04:33 EST news160409033 (PhysOrg.com) -- "Many groups have been working devices that make objects invisible," Che Ting Chan tells PhysOrg.com. `Most of these devices, however, encompass the object to be cloaked.` Chan, a scientist at The Hong Kong University of Science and Technology, believes that it is possible to create a cloaking device that would be able to render an object invisible without encompassing it. http://www.physorg.com/news156162633.html Physics Fri, 13 Mar 2009 11:31:29 EST news156162633 J.K. Rowling may not have realized just how close Harry Potter's invisibility cloak was to becoming a reality when she introduced it in the first book of her best-selling fictional series in 1998. Scientists, however, have made huge strides in the past few years in the rapidly developing field of cloaking. Ranked the number five breakthrough of the year by Science magazine in 2006, cloaking involves making an object invisible or undetectable to electromagnetic waves. http://www.physorg.com/news155477880.html Other Sciences Thu, 05 Mar 2009 12:18:28 EST news155477880 A detailed analysis of the measurements of five different satellites has revealed the existence of the warm plasma cloak, a new region of the magnetosphere, which is the invisible shield of magnetic fields and electrically charged particles that surround and protect Earth from the onslaught of the solar wind. http://www.physorg.com/news148316137.html Space & Earth Fri, 12 Dec 2008 14:55:37 EST news148316137 Rather than building stronger ocean-based structures to withstand tsunamis, it might be easier to simply make the structures disappear. http://www.physorg.com/news141617575.html Physics Fri, 26 Sep 2008 03:12:55 EST news141617575 Harry Potter beware! A team of Chinese scientists has developed a way to unmask your invisibility cloak. According to a new paper in the latest issue of Optics Express, the Optical Society's (OSA) open-access journal, certain materials underneath an invisibility cloak would allow invisible objects be seen again. http://www.physorg.com/news139625813.html Physics Wed, 03 Sep 2008 01:56:53 EST news139625813
