Report suggests more rigorous assessment of nanosilver use

first_img More information: Nanosilver Revisited Downstream, Bernd Nowack, Science 19 November 2010: Vol. 330 no. 6007 pp. 1054-1055. DOI:10.1126/science.1198074 These hand sanitizers and many other consumer products on the market contain nanosilver. Nanosilver is the most commonly used nanoparticle found in consumer goods, and is being used as an anti-odor, antibacterial agent in fabrics, deodorants, toothpastes, and even cement. It is also found in a wide range of other applications, including paints, medical devices, bandages, food containers, and electronics equipment and washing machines. Silver is widely used because it is believed to be harmless to humans except in high concentrations, but it is known to be toxic to fungi, bacteria and other microorganisms, and little is known about its effects on wastewater systems or the wider environment. Previous studies in Europe have shown that around 15 percent of the total volume of silver in wastewater is biocidal nanosilver originating in consumer goods and medicinal uses.Author of the report, Dr. Bernd Nowack of the Swiss Federal Laboratory for Materials Science, Empa, said that while silver has long been known to be a biocide, nanosilver seems to have unique properties because of the nano-scale (less than 100 billionths of a meter) size of the particles. He said this suggests there should be more rigorous assessments of the risks to humans and the environment.Dr. Nowack said one of the risks arises because some of the wastewater and sludge from sewage treatment plants ends up on farms in fertilizers, and could therefore enter the food chain. Another risk is that nanosilver could have a detrimental effect on the nitrifying bacteria that are vital to the effluent treatment processes, and could prevent treatment plants from working properly.Nowack’s report said in earlier studies some nanosilver had been shown to bond with sulfur in sewage sludge to produce non-toxic silver sulfide nanoparticles, but it is not known how efficient sulfur is at removing biocidal silver.In the US and many other countries manufacturers have no obligation to disclose the presence of nanoparticles in consumer goods.

Inspector General audit finds problems with NASAs cloud computing efforts

The idea is that doing so will save the government a lot of money. In following the directive, however, it appears that managers at NASA have failed to ensure that cloud operations are undertaken with the knowledge and approval of the agencies top information officer. Worse, it appears that many of the cloud initiatives were undertaken without due consideration given to necessary security precautions that must be put in place when applications and data become accessible across the Internet.More specifically, the auditors found over a 100 NASA websites—both internal and external—had never been tested for security integrity. Incredibly, many of those same websites were found to have no security controls in place at all.Government agencies have two main options when moving applications to the cloud—set up facilities on their own or contract out. NASA, like most other federal agencies has chosen the latter. Unfortunately, the auditors found that officials at the agency in many cases failed to include security issues when writing contracts, which of course resulted in them not being put in place.Overall, the IG’s report has found that weaknesses in cloud applications have impeded the agency from reaping the benefits of cloud computing—namely reducing costs. And worse, the approach taken thus far has put NASA data at risk. Out of five contracts reviewed, the auditors found “none came close” to operating with industry standard security precautions.The auditors recommend that NASA set up an office dedicated to cloud computing and the security issues that must be put in place when such initiatives are undertaken.

Researchers to use exosuit to explore ancient Antikythera wreck

first_img Deep-Diving Exosuit The team has scheduled a test run of the suit this summer at a site called the Canyons off the coast of Rhode Island. If all goes well, plans for exploring the Antikythera wreck can proceed, paving the way for a whole new way to explore undersea wrecks from virtually any era. More information: The Exosuit: www.amnh.org/exhibitions/past- … ibitions/the-exosuitvia Newscientist (Phys.org) —Marine archeologists with the Hellenic Ministry of Culture research program (with support from the Woods Hole Oceanographic Institution) are planning to explore the ancient Greek Antikythera wreck in the Agean Sea, using an exosuit developed by Nuytco Research—originally for use in helping workers in New York’s water treatment facilities. The iron-man looking exosuit allows a diver to descend to 1000 feet for hours at a time without need for decompressing upon returning to the surface. This document is subject to copyright.

But it also led to injury and death due to the extreme depth (120 meters). Subsequent attempts more recently have led to more discoveries, but time constraints have prevented a thorough study of the wreck. Wearing the exosuit, the researchers hope will not only allow for mapping the wreck, but for discovery of more artifacts, some perhaps as interesting as the Antikythera mechanism.The suit, which is essentially a body submarine, allows for both arm and leg movements, courtesy of multiple patented rotary joints. It also has 1.6 horsepower thrusters that are activated by the “pilot” via pads inside the boots. It’s made of mostly aluminum, and weighs 530 pounds. The hands are claw-like, which has meant many hours of training in pools for the research team. The suit also has external LED lights and cameras, an oxygen replenishment system and a tether to the surface with a fiber optic gigabit Ethernet that allows for two-way communications, a live video feed, and monitoring of the suit and its wearer. In the event of an emergency, the suit has backup batteries and systems to maintain life support—if necessary, the four man crew up top can take over control of the suit to bring the diver out of harm’s way. © 2014 Tech Xplore Citation: Researchers to use exosuit to explore ancient Antikythera wreck (2014, June 5) retrieved 18 August 2019 from https://phys.org/news/2014-06-exosuit-explore-ancient-antikythera.html Archaeologists return to ancient Greek ‘computer’ wreck site: official Explore furtherlast_img read more

Researchers outline the process by which viruses spread from bats to humans

first_img Citation: Researchers outline the process by which viruses spread from bats to humans (2014, November 12) retrieved 18 August 2019 from https://phys.org/news/2014-11-outline-viruses-humans.html Bats identified as hosts of Bartonella mayotimonensis Journal information: Proceedings of the Royal Society B Zoonosis. A dog with rabies. Credit: CDC (Phys.org) —A large team of researchers with members from the U.S. and Australia has created a paper that delineates the cross-species spillover dynamic involved with viruses that spread from bats to humans. In that paper, published in Proceedings of the Royal Society B: Biological Sciences, the team concludes that the relatively recent trend of humans contracting more and more diseases that originate in bats is likely due to human activities such as encroachment on land already being used by bats. More information: Ecological dynamics of emerging bat virus spillover, Proc. R. Soc. B, 7 January 2015 vol. 282 no. 1798 20142124 Published 12 November 2014. DOI: 10.1098/rspb.2014.2124 AbstractViruses that originate in bats may be the most notorious emerging zoonoses that spill over from wildlife into domestic animals and humans. Understanding how these infections filter through ecological systems to cause disease in humans is of profound importance to public health. Transmission of viruses from bats to humans requires a hierarchy of enabling conditions that connect the distribution of reservoir hosts, viral infection within these hosts, and exposure and susceptibility of recipient hosts. For many emerging bat viruses, spillover also requires viral shedding from bats, and survival of the virus in the environment. Focusing on Hendra virus, but also addressing Nipah virus, Ebola virus, Marburg virus and coronaviruses, we delineate this cross-species spillover dynamic from the within-host processes that drive virus excretion to land-use changes that increase interaction among species. We describe how land-use changes may affect co-occurrence and contact between bats and recipient hosts. Two hypotheses may explain temporal and spatial pulses of virus shedding in bat populations: episodic shedding from persistently infected bats or transient epidemics that occur as virus is transmitted among bat populations. Management of livestock also may affect the probability of exposure and disease. Interventions to decrease the probability of virus spillover can be implemented at multiple levels from targeting the reservoir host to managing recipient host exposure and susceptibility.center_img © 2014 Phys.org Explore further This document is subject to copyright.

In recent years, bats have joined the list of animals (birds, pigs, etc.) that harbor so named zoonoses—infections that move between species. One of those diseases in the news is the Ebola virus, which many scientists believe originated in bats. Sadly, our knowledge of how viruses move from one species to another is still rather limited, the authors note, which means a lot of work needs to be done. Figuring out how it happens might help prevent it from happening in the future. To further that cause, the researchers with this effort have outlined the path by which diseases make their way from bats to humans.The researchers don’t know how bats get a disease in the first place, but suspect its part of a process that has been going on for thousands of years. Bats live closely together and tend to infect others of their kind quite rapidly. But, over time, the bats have developed an immunity of sorts. They get the disease, but it doesn’t kill them, or stop them from living their lives—and that’s part of the problem. They leave behind urine, feces and saliva, all of which can serve as a carrier to another species—horses, for example, or monkeys. If a horse eats the grass that is growing under a tree habituated by bats, it’s very likely to get a disease. This happened with the Hendra virus in Australia. And if that horse makes its way back to the barn, it’s likely to infect other horses that live there. And if a human being takes care of that horse, that person is likely to become infected as well.It’s all happening, the researchers claim, because humans are cutting down trees used by bats and using the land for other purposes—to put up houses, for example, some of which have trees in their yards. If they are fruit trees, the bats will take up residence, increasing the likelihood of a virus being spread to the people who live there. They note that getting rid of bats is not an option—that would be an ecological disaster—instead they suggest that the best way to prevent viruses jumping to people is to stop people from encroaching on the land where bats live.last_img read more

General principles to explain DNA brick selfassembly

(C) Incidental interactions between dangling ends, shown in orange, lead to incorrect associations between fragments.

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. (Phys.org)—DNA bricks are an odd phenomenon. They are nanostructures built from synthetic, single-strand DNA that self-assemble into 3D structures. Several years ago, researchers at Wyss Institute at Harvard demonstrated the self-assembly of designed 3D structures made from 1,000 “bricks” that fit together like molecular Legos. One of the curiosities about these DNA bricks is why this complex self-assembly process works so well. Journal information: Proceedings of the National Academy of Sciences In an effort to uncover the nuances of DNA brick self-assembly, William M. Jacobs, Aleks Reinhardt, and Daan Frenkel from the University of Cambridge conducted theoretical studies to understand what drives the assembly process. Their studies reveal how temperature, kinetics, coordination number, and bond energies, contribute to the unique behavior of DNA brick self-assembly, and while it is a nucleated process, it does not behave according to classical nucleation theory. Their work appears in the Proceedings of the National Academy of Sciences.In order to optimize DNA brick assembly, Jacobs, et al. wanted to investigate whether these systems had a nucleation barrier. In classic nucleation theory (CNT), the nucleation barrier is the energy cost for making an ordered structure, such as a crystal. This energy barrier must be overcome before a compound can settle into its equilibrium structure. The authors found that DNA brick assembly does have a nucleation barrier, but, unlike CNT, this barrier is determined by the way the bricks are connected in the target structure. They identified several factors that contribute to this non-classical behavior.DNA bricks are designed to assemble in particular ways by matching certain sections of a DNA strand with a complimentary section. These designed interactions need to be stronger than incidental interactions. They found that there is a critical number of DNA strands that must be assembled to promote the formation of the target structure, meaning that the the nucleation barrier is a consequence of the number of subunits that must be assembled.Additionally, DNA-bricks have a certain temperature range at which the nucleation barrier is overcome, but over which the free energy of the final structure is higher than the initial monomers. This deviates from CNT which predicts that a nucleus with more than the critical number of DNA strands will assemble into the complete structure. This difference is due to DNA bricks forming stable intermediate structures. Experimentally, this means that self-assembly occurs in a narrow temperature range in which nucleation begins at a high temperature, and as the structure is gradually cooled, the target structure is favored.In prior studies, the maximum number of bonds made by each brick in the interior of a structure was four, but it is possible to have different coordination numbers. The question was whether the coordination number affected the nucleation barrier, and whether four bonds were necessary. It turns out that DNA brick self-assembly works well because each subunit makes only a small number of bonds. When the authors tested higher coordination numbers, they found that the system behaved analogously to CNT.Finally, Jacobs et al. found that contrary to theories that homogenous bond energies would decrease the number of errors during DNA brick assembly, it is the diversity in bond energies that contributes to enhanced kinetics of DNA brick self-assembly. This was likely due to stabilizing unstable intermediate structures.Jacobs, et al. have identified several key features that aid in understanding why DNA brick self-assembly works as well as it does. Features such as ramping down the temperature and optimizing the coordination number explain why there are so few errors in the self-assembly process. And, their discovery that heterogeneous bond energies promote target molecule formation is a practical place where researchers can improve yields and decrease errors in DNA brick assembly. More information: “Rational design of self-assembly pathways for complex multicomponent structures” PNAS, DOI: 10.1073/pnas.1502210112AbstractThe field of complex self-assembly is moving toward the design of multiparticle structures consisting of thousands of distinct building blocks. To exploit the potential benefits of structures with such “addressable complexity,” we need to understand the factors that optimize the yield and the kinetics of self-assembly. Here we use a simple theoretical method to explain the key features responsible for the unexpected success of DNA-brick experiments, which are currently the only demonstration of reliable self-assembly with such a large number of components. Simulations confirm that our theory accurately predicts the narrow temperature window in which error-free assembly can occur. Even more strikingly, our theory predicts that correct assembly of the complete structure may require a time-dependent experimental protocol. Furthermore, we predict that low coordination numbers result in nonclassical nucleation behavior, which we find to be essential for achieving optimal nucleation kinetics under mild growth conditions. We also show that, rather surprisingly, the use of heterogeneous bond energies improves the nucleation kinetics and in fact appears to be necessary for assembling certain intricate 3D structures. This observation makes it possible to sculpt nucleation pathways by tuning the distribution of interaction strengths. These insights not only suggest how to improve the design of structures based on DNA bricks, but also point the way toward the creation of a much wider class of chemical or colloidal structures with addressable complexity.center_img Citation: General principles to explain DNA brick self-assembly (2015, May 19) retrieved 18 August 2019 from https://phys.org/news/2015-05-principles-dna-brick-self-assembly.html © 2015 Phys.org Crystallizing the DNA nanotechnology dream: Scientists have designed the first large DNA crystals Explore furtherlast_img read more

Programming human cells to follow sets of logical instructions

first_img This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. (Phys.org)—A team of researchers at Boston University has developed a new way to engineer mammalian cells that allows for programming them to behave in desired ways. In their paper published in the journal Nature Biotechnology, the team describes their technique and where they believe such technology is heading. Explore further As scientists around the world look for new ways to prevent and treat diseases, new techniques are emerging, some of which involve programing human cells to behave in desired ways—such as killing cancer cells. In this new effort, the researchers have developed a new way to program mammalian cells using DNA recombinases.To learn how to program cells researchers have worked with simple organisms such as bacteria, which has led to the use of proteins called transcription factors that regulate genes. Unfortunately, that technique has proven unsuitable for programming mammalian cells because it does not produce the same results consistently in all environments. To get around that problem, the researchers instead chose to work with DNA recombinases—enzymes that can be used to cut DNA in predesignated ways and put them back together in new and useful ways.Cutting DNA and sewing it back together allows for programming cells because DNA controls which proteins a cell makes. By cutting and sewing in a certain way, the researchers were able to induce a human kidney cell to produce a fluorescent protein which caused the cell to light up under desired conditions. Inserting other snippets allowed for modifying recombinases that were activated only in the presence of a certain chemical. By cutting multiple DNA snippets, adding new ones and sewing them back together, the researchers found that they were able to create 113 unique circuits that demonstrated a 96.5 rate of success. In one instance, they created a bio-circuit that mimicked a Boolean lookup table—it had six inputs that allowed for executing 16 logical operations.The work by the team was a proof of concept, they’re optimistic that their technique could be used to create new therapies such as bolstering the immune system by programming T cells—perhaps causing them to attack tumor cells. Another possibility is using the technique to program stem cells to grow into desired tissue.

Large-scale design of robust genetic circuits with multiple inputs and outputs for mammalian cells, Nature Biotechnology (2017). DOI: 10.1038/nbt.3805AbstractEngineered genetic circuits for mammalian cells often require extensive fine-tuning to perform as intended. We present a robust, general, scalable system, called ‘Boolean logic and arithmetic through DNA excision’ (BLADE), to engineer genetic circuits with multiple inputs and outputs in mammalian cells with minimal optimization. The reliability of BLADE arises from its reliance on recombinases under the control of a single promoter, which integrates circuit signals on a single transcriptional layer. We used BLADE to build 113 circuits in human embryonic kidney and Jurkat T cells and devised a quantitative, vector-proximity metric to evaluate their performance. Of 113 circuits analyzed, 109 functioned (96.5%) as intended without optimization. The circuits, which are available through Addgene, include a 3-input, two-output full adder; a 6-input, one-output Boolean logic look-up table; circuits with small-molecule-inducible control; and circuits that incorporate CRISPR–Cas9 to regulate endogenous genes. BLADE enables execution of sophisticated cellular computation in mammalian cells, with applications in cell and tissue engineering.

first_imgKolkata: Howrah city police is going to organise an awareness campaign in which students from Madrassas will be interacting with policemen, who are experts in traffic management, on a one-to-one basis, at Safe Drive Save Life Park. The move was taken considering it will help Madrassa students learn about road safety in details and they can circulate the message of safe drive save life among more people including their family members.A unique Park has been set up off Foreshore Road and it has been named after this statewide road safety campaign, ‘Safe Drive Save Life’, which was launched by Chief Minister Mamata Banerjee to check road accidents. Also Read – Heavy rain hits traffic, flightsHowrah city police has so far taken several initiatives to create awareness among people on road safety. A park has been set up beside Foreshore Road through which thousands of people pass everyday. The decorative pieces and paintings in the park, which were done based on the theme ‘Safe Drive Save Life’, attracts attention of all passersby and it creates awareness among people. A senior officer of Howrah city police said around 50 students from different Madrassas in Kolkata’s twin City will be participating in the programme that is going to be held at Save Drive Save Life Park on Saturday. Senior officers of Howrah city police including those who are mainly involved with regular traffic management and road safety issues will be present at the venue. As per the plan, the officers will be interacting directly with the students. First, they will give a brief description on road safety and traffic related matters to the students and subsequently they will also explain the aspects related to traffic management as per the queries of the students present. It may be mentioned that Kolkata Police, district police and all the police commissionerates under it have organised several awareness programmes in schools and colleges.
