first_imgHoya Robot Two Robot Chefs Make Omelets Hoya Robot has developed a Firefighters Assistance Robot (dubbed a Fire Spy Robot), a remote-controlled device that can reconnoiter a burning structure, transmitting images, sounds, and data on temperature, smoke, and gas to firefighters over 50 yards away. This kind of information is vital for firefighters to ensure their safety before entering a burning structure.The little two-wheeled robot can roam through the blaze spraying water from a fire hose and looking for trapped people. Its onboard light and camera helps firefighters pin-point people before they enter the building themselves. The robot also gives them enough information to decide on the safe routes, and quickly develop a rescue plan.

SETI telescope array suspends operations due to financial constraints

first_img Built in 2007, at a cost of $50 million (half of which came from its namesake, Microsoft co-founder Paul Allen), the array, located north of San Francisco, is comprised of 42 dishes and is connected to 64 quad-core Dell 6100 servers, donated by Dell, Google, and Intel, that sift through 100 to 200TB of data each day in hopes of finding a sign of non-terrestrial signals.The array has been put into hibernation mode, with a skeleton crew to keep it from deteriorating, while SETI looks for new sources of cash. Until now, its operating funds have come from the state of California (the University of California, Berkeley is responsible for operating the ATA) the National Science Foundation, NASA and other private donors. But as California and the rest of the nation suffered through hard economic times, so too did SETI as donations dwindled and budgets were cut. So, instead of adding more dishes (350 were originally planned) and putting the source code for the data scanning algorithms on the “cloud” via Amazon, the group is instead scrambling to simply stay alive.Tom Pierson, CEO of the SETI Institute, which is based in Mountain View, California, broke the news in an open letter to donors, posted April 22; and Franck Marchis, astronomer and a Principal Investigator for SETI, confirmed the mothballing of the ATA on his blog. The news was not unexpected, however, as SETI has seen its donations over the past two years, literally dry up and disappear.In his blog, Marchis, mentions that the ATA is used for more than just alien searching; it’s been used to study all sources of intergalactic radio wave sources, for example and has been used to help with the study of black holes and other unexplained phenomena. He also notes that the U.S. Air Force is interested in using the array to help track space debris, and if so, the hope is that some type of sharing arrangement can be worked out, at least until SETI finds another donor with very deep pockets. © 2010 PhysOrg.com (PhysOrg.com) — SETI, the Search for Extraterrestrial Intelligence group that has been using radio telescopes since the 1960’s to “listen” for signals from deep space that could prove the existence of other life in the universe, has had to temporarily suspend operation of its Allen Telescope Array, (ATA) due to a lack of funding.

Silkworms spinning spider webs

first_img Firm uses genetic modification to coax spider silk from silkworms © 2011 PhysOrg.com (PhysOrg.com) — A spiders silk is strong and more elastic and has a large range of possible medical applications. However, spiders have a history of being territorial and prone to cannibalism, so the idea of having a large population to produce commercial amounts of silk is not possible. However, silk worms have been producing their silk commercially for some time. Journal information: Proceedings of the National Academy of Sciences This document is subject to copyright.

Citation: Silkworms spinning spider webs (2012, January 3) retrieved 18 August 2019 from https://phys.org/news/2012-01-silkworms-spider-webs.html More information: Silkworms transformed with chimeric silkworm/spider silk genes spin composite silk fibers with improved mechanical properties, PNAS, dx.doi.org/10.1073/pnas.1109420109 It was this idea that led Professor Don Jarvis from the University of Wyoming to develop a way to genetically modify the silkworm to spin silk with spider protein. The results of this recent research have been published in the Proceedings of the National Academy of Sciences.These new genetically modified silkworms are able to produce composite fibers that contain silk threads from both the spider and the silk worm.On average, these fibers have proven stronger than the fibers produced by either the silkworm or the spider. This could possible open the door for large scale production and the use of these fibers in many different medical applications.Possible applications include artificial ligaments and tendons, tissue scaffolds and new biomaterials for wound dressing. The fibers are also strong enough that they could provide a possible new material to be used in bulletproof jackets and vests.In order to make this happen, the researchers transferred the key spider genes responsible for the thread making into the silkworm. Given that silkworms are capable of creating mile-long threads in their cocoons, they provide a way to greatly increase the stronger threads.This is not the first time that researchers have tried to create genetically modified spider alternatives. Synthetic spider genes have been placed into bacteria, animals and plants. However, none of these were able to produce enough pure silk protein needed for commercial production. The successful use of the silkworm may prove to finally be the solution they have been looking for. Explore furtherlast_img read more

Researchers conduct first quantitative study of liquid water combining dielectric relaxation and

first_img Journal information: Physical Review Letters © 2016 Phys.org As many researchers have found, water is far more complex than it appears at first glance—it is made of H2O molecules that are connected via hydrogen bonds that form and break over time as the water is subjected to other external objects, processes and forces. In this new effort, the researchers note that many spectroscopic techniques have been used to study the underlying mechanisms involved in water action, revealing such things as dielectric relaxation (amount of time it takes for electrons to return to an equilibrium state after being excited), amounts of infrared absorption, Ramen and neutron scattering and the absorption of x-rays. Researchers have combined techniques that involved neutron scattering and dielectric relaxation in the past, but they involved only qualitative observations. In this new effort, the researchers have done so quantitatively.By conducting a variety of experiments on dielectric relaxation, the team found that they were able to depict the relaxation of dipoles in liquid water—the part of the process that is responsible for determining its overall dielectric response. And by conducting other experiments involving neutron scattering, they were able to better understand the connection between molecular dynamics and dielectric behavior. By looking at the results together, the researchers were able to confirm the existence of two processes related to the way molecules are diffused and the associations that are involved when hydrogen bonds are forged and broken. Also, they note their work revealed three processes at frequencies below 3 THz—local, relaxational and vibrational and diffusive. The team notes also that their findings are similar in some respects to experimental observations of molecular actions in polymers. Researchers explain a decades-old conundrum over the dielectric response of ice Explore further (Phys.org)—A team of researchers from several institutions in Spain and France has conducted the first quantitative study of liquid water combining dielectric relaxation and neutron scattering, and in so doing, has revealed three processes at frequencies below 3 THz. In their paper published in the journal Physical Review Letters, the team describes how they combined two water analysis techniques to gain a better understanding of the mechanisms that control the dielectric constant.center_img Citation: Researchers conduct first quantitative study of liquid water combining dielectric relaxation and neutron scattering (2016, October 25) retrieved 18 August 2019 from https://phys.org/news/2016-10-quantitative-liquid-combining-dielectric-neutron.html Credit: George Hodan/public domain This document is subject to copyright.

More information: A. Arbe et al. Dielectric Susceptibility of Liquid Water: Microscopic Insights from Coherent and Incoherent Neutron Scattering, Physical Review Letters (2016). DOI: 10.1103/PhysRevLett.117.185501ABSTRACTThe analysis of neutron scattering results on H dynamics (H2O) and the dynamic structure factor (D2O) around the intermolecular peak and at intermediate length scales in terms of the susceptibilities reveals three processes (diffusive, local relaxational and vibrational) at frequencies below 3 THz, to which the contributions commonly invoked in dielectric studies can be directly mapped. We achieve a unified description of the results from both techniques, clarifying the nature of the molecular motions involved in the dielectric spectra and their impact on the structural relaxation.last_img read more

ED seeks Red Interpol notice against Lalit Modi

first_imgIn fresh bid to bring former IPL chairman Lalit Modi back to India, the Enforcement Directorate (ED) has sought an Interpol notice against him in connection with its probe in a money laundering case relating to alleged financial irregularities in the operations of various editions of the T-20 cricket tournament.Officials said the agency’s Mumbai office officially moved for a ‘Red Interpol notice’ against Modi on the basis of a non-bailable warrant (NBW) issued recently by a special court. Also Read – Need to understand why law graduate’s natural choice is not legal profession: CJIThe agency has sought the global notice, sources said, as domestic legal remedies to serve its earlier issued Prevention of Money Laundering Act (PMLA) notice on Modi had not met with any success even as the ED alleged that Modi did not cooperate with it in this probe till now.The ED headquarters, sources said, later forwarded the legal request to the CBI head office here to get a notice issued through the latter’s Interpol wing.A CBI spokesperson said the request had been received on Tuesday afternoon from the ED and it will be processed after due verification. CBI is the nodal agency for Interpol related affairs in India. Modi is currently based in the United Kingdom. Also Read – Health remains key challenge in India’s development: KovindThe ED, sources said, has sought a ‘Red notice’ which is issued “to seek the location and arrest of wanted persons with a view to extradition or similar lawful action” in a criminal case probe. Once the Red notice is sounded, the Interpol seeks to arrest the person concerned in any part of the world and notifies that country to take his or her custody for further action at their end.ED had last month moved a special PMLA court in Mumbai seeking NBW against Modi after he did not respond to summons sent to him. Sources said the agency is also mulling to seek extradition of Modi by sending a request in this regard to the Ministry of External Affairs (MEA) through the Home Ministry.  The agency is probing Modi, the Indian Premier League (IPL) and its executives under anti-money laundering laws under its criminal FIR registered in 2012 after taking cognizance of a cheating complaint filed by former BCCI chief N Srinivasan against Modi and half a dozen others with the Chennai police.The ED subsequently invoked the PMLA along with section 420 (cheating) and 120-B (criminal conspiracy) of the IPC to probe if BCCI-IPL and the exchequer had been cheated in the award of telecast rights for the IPL in 2009.It is also probing 16 foreign exchange violation cases vis-a-vis IPL, Modi and others and the most important one amongst these is that related to the media rights deal where the agency slapped show-cause notices against Modi and 13 others in February this year.last_img read more
