Here we propose an approach to diagnosing the presence and drug-susceptibility of infectious diseases based on direct detection of RNA from clinical samples. We demonstrate that species-specific RNA signatures can be used to identify a broad spectrum of infectious agents, including bacteria, viruses, yeast, and parasites. Moreover, we show that the behavior of a small set of bacterial transcripts after a brief antibiotic pulse can rapidly differentiate drug-susceptible and -resistant organisms and that these measurements can be made directly from clinical materials. Thus, transcriptional signatures could form the basis of a uniform diagnostic platform applicable across a broad range of infectious agents.via Discover Blogs This document is subject to copyright.

In recent years, people in the medical profession have had to rely on DNA analysis to identify certain pathogens, which can take days, or even sometime weeks to carry out. Time that could be better spent treating the diseases they cause. The research team, led by Deborah T. Hunga, following up on findings by Amy Barczak has found that focusing on RNA molecules instead offers much more timely results.The probes are based on the fact that when DNA molecules are switched on, they pass on information to RNA molecules, which are far more prevalent in the body and thus easier to find and look at. Thus, when DNA molecules are switched on due to coming under attack by a pathogen, RNA molecules are notified, which opens up the possibility of simply watching RNA molecules for reactions instead of testing DNA directly. That’s just what the team has done. They’ve created so-called glowing probe molecules that physically light up when they come into contact with the material that is transmitted to RNA molecules from DNA when it comes under attack. And because different DNA molecules switch on for different germs, the message sent is different causing specific probes to light up, which allows for identifying which pathogen has struck.In lab tests, the glowing probes have been able to identify HIV, herpes, influenza, several kinds of bacteria and even the fungus that causes thrush. The team believes that their probes could be used together to test for a variety of ailments in one fell swoop, saving countless hours.As impressive as their results are thus far, there’s more to the story. The team also found that their glowing probes were also able to discern whether a discovered bacteria was drug-susceptible or resistant, a result that could save precious time when trying to figure out the most appropriate drug to use to treat patients infected with dangerous pathogens.Because their research is still so new, more work will need to be done to ensure that the probes are as accurate as they seem and to figure out exactly which pathogens can be identified by them and which cannot. ( — A team of researchers from the Boston area have developed a “glowing probe” molecule that is able to detect the presence of many common types of bacteria, viruses and even fungi. The results of their work, which they describe in their paper published in the Proceedings of the National Academy of Sciences, show that the molecular probes can be used to help diagnose diseases. © 2012 PhysOrg.comlast_img read more

Britain to use spent nuclear fuel for batteries to power deep space

first_img Citation: Britain to use spent nuclear fuel for batteries to power deep space craft (2012, September 14) retrieved 18 August 2019 from © 2012 Explore further The idea would follow designs already used by the United States to power its Cassini and Voyager space probes and now in use by the Mars rover, Curiosity. Nuclear material gives off heat for many years, which can be used directly to keep a craft warm, or be converted into electricity for use by electronic components. The team has reportedly already harvested some amount of americium-241 from the plutonium waste left over from the production of nuclear weapons. The Sellafield facility reprocesses or separates plutonium, uranium and other fissionable materials from spent nuclear fuel, some of which is used for other purposes such as creating new fuel for nuclear reactors. It’s also the site of what will be a new nuclear power station due to begin operation in 2025.The ESA is keen to find a suitable replacement for plutonium-238, as it’s only currently available from the United States and Russia, and believes americium-241, harvested from already existing plutonium waste would make a good choice. Each nuclear battery would only need about 5 kg of the material, which would mean Britain could supply all that would be needed (the Sellafield facility is believed to house some 100 tonnes of waste plutonium) by the ESA for the foreseeable future. Batteries made using it could be used to support missions to other planets and other exploratory projects.It’s also been noted that such batteries could be used for other purposes as well, such as in long term undersea probes, or in buoys outfitted with sensors to monitor sea conditions and other countries such as China and India have already expressed interest in using them for various projects. Thus, the market for long duration nuclear batteries might be expanding, which would make harvesting americium-241 not only cost efficient but perhaps at some point, profitable.

Researchers explore the use of decision pathways to inform climate engineering policies

first_imgCredit: public domain Journal information: Proceedings of the National Academy of Sciences Citation: Researchers explore the use of decision pathways to inform climate engineering policies (2016, January 13) retrieved 18 August 2019 from More information: Robin Gregory, Terre Satterfield, and Ariel Hasell. Using decision pathway surveys to inform climate engineering policy choices. PNAS 2016 ; published ahead of print January 4, 2016, DOI: 10.1073/pnas.1508896113AbstractOver the coming decades citizens living in North America and Europe will be asked about a variety of new technological and behavioral initiatives intended to mitigate the worst impacts of climate change. A common approach to public input has been surveys whereby respondents’ attitudes about climate change are explained by individuals’ demographic background, values, and beliefs. In parallel, recent deliberative research seeks to more fully address the complex value tradeoffs linked to novel technologies and difficult ethical questions that characterize leading climate mitigation alternatives. New methods such as decision pathway surveys may offer important insights for policy makers by capturing much of the depth and reasoning of small-group deliberations while meeting standard survey goals including large-sample stakeholder engagement. Pathway surveys also can help participants to deepen their factual knowledge base and arrive at a more complete understanding of their own values as they apply to proposed policy alternatives. The pathway results indicate more fully the conditional and context-specific nature of support for several “upstream” climate interventions, including solar radiation management techniques and carbon dioxide removal technologies.

It’s a global challenge at a scale requiring the mobilization of resources that only nation states are capable of, and public input into policies related to mitigating climate change is particularly important. Traditional survey techniques provide a snapshot of public opinion from which policymakers can draw conclusions, but such surveys have inherent limitations because people use a variety of mental models to interpret information and make sense of policy options.center_img Explore further A collaborative of researchers from the U.S. and Canada propose a decision pathway approach that offers some of the benefits of traditional survey techniques, while also capturing the reasoning of deliberations within groups, and helping participants to deepen their knowledge of issues and solutions. The researchers have modeled this approach with a decision pathway design that addresses climate engineering technologies, and published their results in the Proceedings of the National Academy of Sciences.The authors write, “Decision pathway survey designs seek first to inform people, about both their own values and the facts relevant to multisided public policy choices, and then to provide decision makers with information about both what and how citizens think without reliance on more costly, and less scalable, qualitative research methods.”The prescriptive model adopted for the study is PrOACT, an acronym describing its five basic steps: understand the problem context; clarify objectives; define alternatives; identify consequences; highlight key tradeoffs. Responses are iterative, as participants revisit earlier questions in light of information presented during later stages. The pathway survey emphasized climate engineering technologies that capture and store carbon dioxide before it is released into the atmosphere, or technologies that reflect sunlight and its accompanying solar heat before it reaches the Earth’s surface. Keeping in mind that any survey design wields influence over participants as they construct a response, the researchers focused explicitly on the reasoning processes used by individuals as they went through the five steps of the decision pathway.Among their findings:A large majority (70 percent) of those who described themselves as “not at all concerned” about climate change chose “to do nothing more” to mitigate climate change, while the remainder supported transportation alternatives.Shifts in opinions on alternatives occurred in the other groups, who described themselves as “not very concerned,” “fairly concerned,” and “very concerned.”There is an overall pattern among all groups to regard their own views on climate governance as likely to be shared by others.Significantly, all groups rated all categories of risks associated with geoengineering as more likely than all categories of benefits.The authors write, “Results underscore both the nuanced responses of participants and the need for survey methods that can capture and reflect this conditional reasoning. As one example, consistent support for geoengineering exists when interventions involve mostly natural means, including use of biotic infrastructure (e.g., planting new forests, cultivating plankton and algae) and improvements to built infrastructure (e.g., modifying buildings and surfaces to increase reflectivity), across the spectrum of concerns.” The authors note that one shortcoming of their study is that it lacks a control group. Further investigation of decision pathway methodologies could make better comparisons with results from conventional surveys conducted in parallel. © 2016 40-country survey: Majority support for cutting emissionslast_img read more

Scientists express concern over disposal of nuclear waste at New Mexico underground

first_img Explore further (—A trio of Earth and Environmental scientists with hazardous waste backgrounds, from Stanford University, has published a Comment piece in the journal Nature, outlining their concern over a recent proposed plan to add more nuclear waste to the Department of Energy’s, Waste Isolation Pilot Plant (WIPP) located in a deep underground salt formation in New Mexico. The trio, Cameron Tracy, Megan Dustin and Rodney Ewing suggest more thought be put into the idea before the government gives the go-ahead for the project. More information: Policy: Reassess New Mexico’s nuclear-waste repository, The cold war led to the stockpiling of a huge amount of nuclear arms in the U.S. and Russia, as most everyone knows. But it also led to an ever increasing amount of hazardous materials associated with that stockpiling. Now that the arms race has cooled, and the U.S. and Russia have agreed to reduce their stockpiles, a means of dealing with many tons of hazardous materials must be found. To deal with such materials, the U.S. built the WIPP (which is essentially a platform built inside a cave that formed in a layer of salt), where such materials have been placed for storage over the past 15 years. But, now, a team of researchers hired by the government to address a whole new round of disposal requirements has recommended that 34 tons of nuclear waste be added to the WIPP, which the research trio suggests, may be pushing the limits of the facility. They also suggest that safety assessments have not taken into consideration all of the things that could go wrong with the storage faculty—such as how material inside of drums will react with salt over thousands of years after they are crushed, or what might happen if over many years, the WIPP becomes unknown to future generations who at some point begin drilling in the area.The researchers acknowledge the good safety record of the WIPP, just one major problem has occurred, where cat litter was used to sop up material which led to a reaction inside a drum, forcing the lid to pop off, allowing gas to escape. Such accidents are inevitable, the team notes—what they are worried about is the lack of planning regarding what should be done in the event other types of accidents occur—over a 10,000 year timeline. Once the site is sealed in 2033, monitoring will end—there will be no way to know what is going on inside the faculty which means there will be no way to assess whether radioactive material has begun to leach into outside areas or whether carbon dioxide begins to build up due to decay, which can lead to pressure causing fractures to the surface. The group suggests the DOE take a harder look at the safety features that are in place now before adding tons more material to the site.

Graphene photodetector enhanced by fractal golden snowflake

first_imgA graphene photodetector with gold contacts in the form of a snowflake-like fractal pattern has a higher optical absorption and an order-of-magnitude increase in photovoltage, as compared to graphene photodetectors that have contacts with plain edges. Credit: Fang et al. ©2016 American Chemical Society © 2017 The researchers explained that these characteristics can be directly attributed to the fractal pattern. (—Researchers have found that a snowflake-like fractal design, in which the same pattern repeats at smaller and smaller scales, can increase graphene’s inherently low optical absorption. The results lead to graphene photodetectors with an order-of-magnitude increase in photovoltage, along with ultrafast light detection and other advantages. “Our proposed fractal metasurface has the unique ability of supporting plasmonic resonances (free electron oscillations) over a wide spectral range in a polarization-insensitive way due to its complex and highly hexagonally symmetric geometry,” Kildishev said. “Previously reported plasmonic-enhanced graphene photodetectors use simpler narrowband and polarization-sensitive structures, and therefore the enhancement is also narrowband and polarization-sensitive.”As previous research has shown, the reason that a fractal pattern can improve optical absorption is that the fractal metasurface creates additional resonances, with the amount of resonance increasing as the number of fractal levels increases. In addition, the researchers here found that the fractal metasurface confines and enhances the electric field of the light that hits the surface. This ultimately leads to a higher photovoltage generated in the graphene photodetector.As Kildishev explained in more detail, there are two major mechanisms of inducing photovoltage in a graphene-based photodetector: the photovoltaic effect and the photothermoelectric effect. The photovoltaic effect uses the built-in electric field induced by differently doped regions in graphene to separate the optically excited electron hole pairs in graphene. The photothermoelectric effect drives the free electrons in graphene across regions with different thermoelectric powers (Seebeck coefficients), given a temperature gradient in between the two regions. The fractal metasurface enhances both effects in graphene photodetectors by increasing the electric field intensity and by heating via incident light in highly confined spaces.”The fractal metasurface enhances the photovoltage by making use of plasmonic resonance—free electron oscillations in gold under the excitation of light,” Kildishev said. “This then confines the electromagnetic energy to ultra-small volumes, generating excessive electron-hole pairs in graphene which are then separated by the photovoltaic effect. The incident light also heats up the plasmonic structure to create a large temperature gradient across the metal/graphene interface, giving rise to a stronger photothermoelectric response.”In the future, the researchers plan to explore the potential applications of graphene photodetectors, which could extend beyond photodetection to photoharvesting, with applications such as solar cells and optical heating. Technologies that require a fast response could also experience significant improvements due to the graphene photodetector’s fast operation speed.”One great attribute of the graphene photovoltaic/photothermoelectric detector is that it reacts to light at an extremely fast rate, thanks to the ultrafast electron moving speed (photovoltaic effect) and the ultrashort time the electrons need to give away heat (photothermoelectric effect) in graphene,” Wang said. “Such response speed is unparalleled by other photodetection materials. “Plasmonic enhancement has been known to sacrifice the ultrafast response speed to a minor extent. Therefore, plasmonic-enhanced graphene photodetectors are promising for all-optical modulator readout and other applications where response speed is key. Moreover, graphene has zero (or tunable) bandgap and uniform optical absorption in the entire electromagnetic spectrum. Therefore, graphene photodetectors can in principle be used to detect light of any frequency with identical sensitivity, which again is unparalleled by other detectors made of other photodetection materials.” Developing graphene microwave photodetector Explore further This document is subject to copyright.

The researchers, from Purdue University in Indiana, include graduate students Jieran Fang and Di Wang, who were guided by professors Alex Kildishev, Alexandra Boltasseva, and Vlad Shalaev, along with their collaborators from the group of Professor Yong P. Chen. The team has published a paper on the new graphene photodetector fractal design in a recent issue of Nano Letters.Photodetectors are devices that detect light by converting photons into an electric current. They have a wide variety of applications, including in X-ray telescopes, wireless mice, TV remote controls, robotic sensors, and video cameras. Current photodetectors are often made of silicon, germanium, or other common semiconductors, but recently researchers have been investigating the possibility of making photodetectors out of graphene.Although graphene has many promising optical and electrical properties, such as uniform, ultra-broadband optical absorption, along with ultra-fast electron speed, the fact that it is only a single atom thick gives it an intrinsically low optical absorption, which is its major drawback for use in photodetectors. To address graphene’s low optical absorption, the Purdue researchers designed a graphene photodetector with gold contacts in the form of a snowflake-like fractal metasurface. They demonstrated that the fractal pattern does a better job of collecting photons across a wide range of frequencies compared to a plain gold-graphene edge, enabling the new design to generate 10 times more photovoltage.The new graphene photodetector has several other advantages, such as that it is sensitive to light of any polarization angle, which is in contrast to nearly all other plasmonic-enhanced graphene photodetectors in which the sensitivity is polarization-dependent. The new graphene photodetector is also broadband, enhancing light detection across the entire visible spectrum. In addition, due to graphene’s inherently fast electron speed, the new photodetector can detect light very quickly.”In this work, we have solved a vital problem of enhancing the intrinsically low sensitivity in graphene photodetectors over a wide spectral range and in a polarization-insensitive manner, using an intelligent self-similar design of a plasmonic fractal metasurface,” Wang told “To our knowledge, these two attributes were not achieved in previously reported plasmonic-enhanced graphene photodetectors.” Journal information: Nano Letters More information: Jieran Fang et al. “Enhanced Graphene Photodetector with Fractal Metasurface.” Nano Letters.

Mamata to lay foundation stone of Jhargram University today

first_imgKolkata: In a historic move, Chief Minister Mamata Banerjee will lay the foundation stone of Jhargram University on Thursday.The proposed university is coming up on Jhargram- Lodhasuli Road on 27.02 acres of land. It may be mentioned that Banerjee, during her last trip to Jhargram, had announced the setting up of a university to meet the long-standing demand of the student community. Partha Chatterjee, state Education minister, will be present at the programme, which will be held at the Jhargram Stadium. Also Read – Rain batters Kolkata, cripples normal lifeThe university will have five departments to start with. Arts, Social Science, Information Science and Media, Science and Technology and vocational courses. There will be facilities to study the Arts subjects in Olchiki script. With the construction of the university in Jhargram, there will be three universities in Paschimanchal. The two existing universities are Vidyasagar University in West Midnapore and Sidho Kanho University in Purulia.The proposed university will benefit the local students immensely, as they will not have to go to other districts to pursue higher education.

The Maoists had taken control over some of the villages and forced the children not to go to the schools as they were being used as pawns.After coming to power in 2011, Banerjee has made frequent visits to Jhargram, to win the confidence of the people. Projects had been taken up for massive development of the area. A bridge was constructed at Lalgarh. A nursing college, women’s college and super-specialty hospital have come up. To provide better education to the tribal students, Banerjee had requested the then general secretary of the Ramakrishna Order Swami Suhitanandaji, to take over the Eklavya Model Residential School. RKM took over the school and in the past two years, the students have come up with good results.A trilingual dictionary, the only of its kind, has been brought out by the Backward Classes Welfare department (BCW). Distribution of bicycles among the students between classes IX to XII of state-run, aided and sponsored schools has brought down the number of dropouts.Because of the Chief Minister’s initiatives, the road connectivity has improved, resulting in growth in the tourism sector. The unemployed youths are now being given training in hospitality management, which will help them to get jobs in the hotels, lodges and resorts. Banerjee’s plan has opened new areas before the student community.last_img read more

Decomposed body of elderly man found at his residence

first_imgKolkata: Mystery shrouds the death of an elderly man whose decomposed body was recovered from his residence at Chandannagar in Hooghly on Tuesday morning.Locals got a foul smell emanating from his house. After being informed, police reached the spot and entered the house. They found the decomposed body of the victim, Gopinath Mukherjee, lying on the floor of the house. According to a preliminary investigation, police suspect that the victim died a few days ago. Police said that the victim’s younger brother, Apurba Mukherjee, was living with the victim in the house for the past few years. The younger brother was also present when police reached the spot. They came to know that the younger brother had developed some mental issues. Police are yet to ascertain if the victim had died a natural death or there was any foul play behind the incident. They have started a detailed probe in this regard and have failed to interrogate the younger brother as he started shouting at the police officers.
