Explore further Researchers Probe Links Between Modern Humans and Neanderthals The Neanderthal woman died in the Vindija cave in what is now Croatia. Neanderthals are the nearest extinct relative of modern-day humans. Homo sapiens and Neanderthals coexisted for 5-7,000 years, but Neanderthals were gradually forced to retreat to the edges of what is now Europe. The fragments of DNA from the woman’s bones were assembled using human and chimpanzee genomes as references. Researcher Gerald Irzyk said putting the fragments in order is difficult because at first it seems a random assemblage of the nucleotide bases, but there are patterns and motifs that are often specific to a group of organisms.The project to map the genome began in 2005, and is run collaboratively by scientists at the Max Planck Institute in Leipzig, Germany and 454 Life Sciences at Branford, Connecticut. The work has been made possible by today’s powerful computers, which enable scientists to drastically cut the time and cost, but it has still faced many challenges largely through contamination and the breakdown and chemical changes in the biological material over time.When an organism dies, enzymes break DNA into small fragments of only a few hundred base pairs or less. The DNA is also chemically changed over time, which can lead to incorrect interpretations of the sequence. Not only that, but over 90% of the DNA in the samples came from bacteria or other contaminants rather than the bone. Creating body parts, organs, and even a complete living individual once the genome is completely sequenced would be difficult but is theoretically possible. The procedure would involve making possibly millions of changes to the DNA in a human stem cell to match the Neanderthal genetic sequence, but there remain problems because even if the Neanderthal genes could be recreated we do not know how they were expressed. Assuming it can be created, the stem cell with Neanderthal DNA would divide to produce a colony of cells that could then be instructed to become any type of cell in the body, theoretically including an entire individual.Chief science officer of Advanced Cell Technology, Robert Lanza said in Archaeology magazine that “species such as cows and goats are now routinely cloned with few problems,” and while there are many more challenges in the case of cloning a Neanderthal, it possibly could be done. The ethics of such a move would be certain to spark a great deal of debate, and not just between paleoanthropologists.Author of the Archaeology magazine article, Zach Zorich, who has been a keen follower of research on the Neanderthal genome, noted that if created, the Neanderthal would legally deserve the same human rights as we do.It is likely to be quite some time before we need to deal with the ethical issues. Stephan Schuster, a geneticist from Pennsylvania State University, explained that the first draft of the genome will probably contain many errors due to the age of the sample and the contamination, and he calculates the DNA in five different samples of bone would have to be sequenced, and in all the genome would need to be sequenced 30 times before we could be confident of its accuracy.Mapping the genome should allow scientists to answer questions about the relationship between us and Neanderthals, such as whether we interbred, and were separate species. It may also be useful in medical research. Citation: Could Neanderthals live again?

More information: Cryptic asymmetry: unreliable signals mask asymmetric performance of crayfish weapons, Biology Letters, Published online before print March 14, 2012, doi: 10.1098/rsbl.2012.0029AbstractAnimals commonly use their limbs as signals and weapons during territorial aggression. Asymmetries of limb performance that do not relate to asymmetries of limb size (cryptic asymmetry) could substantially affect disputes, but this phenomenon has not been considered beyond primates. We investigated cryptic asymmetry in male crayfish (Cherax dispar), which commonly use unreliable signals of strength during aggression. Although the strength of a chela can vary by an order of magnitude for a given size, we found repeatable asymmetries of strength that were only weakly related to asymmetries of size. Size-adjusted strength of chelae and the asymmetry of strength between chelae were highly repeatable between environmental conditions, suggesting that asymmetries of strength stemmed from variation in capacity rather than motivation. Cryptic asymmetry adds another dimension of uncertainty during conflict between animals, which could influence the evolution of unreliable signals and morphological asymmetry. Crafty Australian crayfish cheat Image credit: Anthony O’Toole © 2011 PhysOrg.com Crayfish, as most who have ever seen them can attest, are naturally aggressive. If you stick your hand in the water, rather than run or hide, a crayfish will grab your fingers with its sharp claws and try to defeat you. Thus, it should come as no surprise that they are just as nasty regarding one another. Upon two males meeting, their natural inclination is to start fighting. But then, sometimes, they don’t. Evolution has added a layer of protection to keep them from completely wiping out their own species by endowing males with different sized claws. Oddly, instead of jumping into action, as might be expected, two males will first size one another up. They’ll lift their claws to show the other how big they are, then lay them down so the other can poke and prod them a little. If one is satisfied that the other has bigger claws, he will leave the scene and a fight will be avoided, which is a good thing, because when they do fight, limbs can be severed and sometimes one or the other ends up dead.But there is more to the story as Angilletta and Wilson found out, because all is not as it seems. They found after studying 97 of the males in action on North Stradbroke Island in Queensland, that claw size doesn’t equate to strength. Some males with large claws had weak muscles, while some with smaller claws had strong muscles; and in crawfish, muscle is more important because it can mean the difference between causing an annoying pinch versus severing a limb or other important body part.The research duo surmise that the crayfish are fully aware of the actual strength of their pinch and thus resort to bluffing if their muscles aren’t up to snuff when they run into another male with smaller, but potentially stronger claws. And because the smaller clawed rival falls for it as much as 80% of the time, many unnecessary fights and the carnage they cause can be avoided.Thus, clearly humans, are not the only species able to bluff their way out of fight.

One of these traits is the ability to lie or cheat. This is because doing so seems to imply a high order of intelligence. Unfortunately, as with many other traits that have once been thought uniquely human, lying, or bluffing appears to occur in other species as well, or at least in one, the lowly male crayfish. In a recent study, Michael Angilletta from Arizona State University and Robbie Wilson of the University of Queensland, found that male crayfish use claw size to bluff their way out of fights with other males. They have published their observations in the Royal Society journal, Biology Letters. Journal information: Biology Letters This document is subject to copyright.

(A) Mirkin predictions using the CCM and (B) predictions from GA using the forward CCM approach. Copyright © PNAS, doi:10.1073/pnas.1316533110 (Phys.org) —Material design usually follows what is known as the Edisonian method, a traditional process characterized by trial-and-error discovery rather than a systematic theoretical approach. While this may be somewhat inaccurate – Edison made use of available theories and resorted to trial and error only when no adequate theory existed – a better alternative is an a priori approach in which desired properties are defined and corresponding structures designed. To that end, scientists at Columbia University – Department of Chemical Engineering and Brookhaven National Laboratory (BNL) have recently created a design approach in which colloids grafted with single-stranded DNA self-assemble into desired structures. The researchers state that their methodology can be easily generalized, is fast and highly selective, accurately reproduces the parameters relevant to four currently realized crystals but also – surprisingly – elucidates four currently unobserved structures. While the scientists acknowledge that these structures need to be experimentally validated, they are confident that their methodology has broad potential applications. Comparison of conventional and proposed paradigms. Copyright © PNAS, doi:10.1073/pnas.1316533110 © 2013 Phys.org. All rights reserved. , Science Addressing these challenges was in itself no mean feat. “Our design problem is made complicated by the complex nonlinear relationships between colloid size ratios, the number of DNA linkers on each nanoparticle and the desired crystal structure,” Venkatasubramanian tells Phys.org. “This leads to a search space riddled with local minima which is difficult to explore using more conventional approaches such as trail-and-error, heuristics or mathematical programming methods.” The key innovation here is the inverse design framework that effectively exploits the knowledge from the CCM (also known as a forward model) by combining it with the genetic algorithm (which is more robust to local minima), thereby resulting in a very efficient and scalable design optimization procedure. “Genetic algorithms are how nature designed complicated molecules and organisms. We’re essentially creating situations where we allow the ‘gene pool’ of DNA-grafting parameters to evolve towards the desired – that is, ‘fittest’ – structure with each successive generation.”Kumar also points out that they introduced the very important analysis of cluster formation determination. “The CCM requires an initial input of crystal lattice parameters and thus assumes crystal formation given any DNA-grafting parameters. However, experimentally, there are large regions of cluster formation that result from the kinetic trapping of these particles in a metastable state during the self-assembly process. In order to prevent design falling within the boundaries of these cluster forming regimes, we performed a symmetry analysis of the model that accounts for unequal distribution of DNA linkers on particles.” In other words, by introducing a cutoff on this distribution, the scientists were able to identify the presence of amorphous and cluster regions that were observed earlier in experiments. “This then allows for future modifications of the framework to incorporate an additional parameter into the fitness function,” he adds, “such that it will recognize and avoid these ‘bad’ evolutionary paths.”Currently, by having a different objective compared to DNA hybridization, the team is including new parameters in the model to enhance the CCM with entropic contributions and repulsive interactions. “Preliminary experimental studies have shown that our refined model is in agreement with experimental results,” Srinivasan and Thi Vo note, “and a thorough analysis is currently being conducted to develop a model that will uniquely specify all 230 different crystal space groups, which will then be used along with the genetic algorithm approach for crystal lattice design. Our ultimate goal is to create the model in such a way that utilizes only the parameters defining the DNA-grafted particles.” The key point here is that this avoids the need for fitting constants while expanding our overall design capabilities, since the design parameters derived from the genetic algorithm framework will only involve factors that the researchers can experimentally control.One interesting and unexpected result was that that their findings elucidated four currently unobserved structures. “Among the crystal lattice library created using the Inorganic Crystal Structure Database (ICSD), we were able to identify the parameters that could potentially lead to the formation of four new crystal structures along with those which have been observed experimentally,” Srinivasan and Vo recount. “These results are promising and play a key role in the design of DNA-grafted nanomaterials.” He adds that the framework is generic and can be extended to rational design of advanced materials – but with a caution that unlike molecular dynamic models, the forward path model should be computationally efficient while accounting for important aspects of the process. “We believe that our enhanced CCM approach should be able to help us design structures that could potentially scan the entire crystallographic space.”In terms of improving the current generic algorithm, Kumarsays that the current CCM has two continuous variables that are optimized for desired crystal structures. “However,” he points out, “with our planned CCM enhancements, this search space will become even larger, and as mentioned replete with local minima that could lead to ambiguous results. We plan to use hybrid genetic, algorithms that use GA in combination with traditional nonlinear optimization approaches to locate the global minima in the large search space of experimental parameters.”Moving forward, Kumar says that other innovations you might develop apart from having ssDNA grafted nanoparticles of spherical shape, the team’s collaborators from Brookhaven National Laboratory (and co-authors of the current work) have performed experiments introducing external motifs of different shapes and its effect on final crystal structure. “Different shapes will allow us to control the interaction range and size between particles, and thereby form crystal lattices that are currently inaccessible from using spherical particles. We’re already investigating these experiments and developing strategies that could be used in the design of various nanocrystal lattices,” he explains.”Our current research focuses on developing entropy-based models to uniquely define the crystal lattices that would explain the formation of DNA grafted nanomaterials,” Kumar continues. “Experiments will validate this model, which will then be used in rational design with the GA framework. In addition, we’re planning to extend this rational design strategy to crystal structures with external motifs that aid in self-assembly.” Addressing other areas of research that might benefit from their study, Venkatasubramanian says that the scientists need a new paradigm that increases the idea flow, broadens the search horizon, and archives the knowledge from today’s successes to accelerate those of tomorrow. “Our framework addresses this challenge, and in a sense, we’re leveraging how nature discovers new materials through the Darwinian model of evolution by suitably marrying it with computational methods. It’s Darwin on steroids! This approach can potentially revolutionize materials design,” he concludes, “impacting a broad range of products that affect our daily lives, from drugs and agricultural chemicals such as pesticides or herbicides to fuel additives, paints and varnishes, and even personal care products such as shampoo.” This document is subject to copyright.

Prof. Venkat Venkatasubramanian discussed the paper that he, Prof. Sanat Kumar, Prof. Babji Srinivasan, Thi Vo from Columbia, and their co-authors, Dr. Oleg Gang and Dr. Yugang Zhang from BNL, published recently in Proceedings of the National Academy of Sciences. “Design of DNA-grafted nanoparticles is challenging because a number of experimental parameters can play a key role in self-assembly,” Venkatasubramanian tells Phys.org. “Parameter space size can therefore become very large, with a large number of local minima, making it very difficult – if not impossible – to efficiently search the space in an Edisonian trial-and-error fashion.” The researchers’ genetic algorithm inverse design framework searches the space more systematically, making the design process more effective. (A genetic algorithm, or GA, mimics the process of natural selection.) That being said, however, Venkatasubramanian adds that another challenge in their approach is that they require reliable forward models. “While detailed models of DNA-mediated self-assembly tend to be more accurate, they would typically require simulation times ranging from several hours to a few days, and thus would not be appropriate for coupling with the genetic algorithm for rational design.” The researchers therefore chose a simpler complementary contact model (CCM) based on the predictable and well-established properties of both DNA (persistence length, rise per base pair) and DNA-NPs (number of DNA strands per particle, the hybridization behavior of sticky ends)1. “CCM has been quite successful in capturing the majority of the experimental observations,” he adds, “and being fast, it allows for effective GA coupling, generating predictions of the required design parameters in a matter of minutes.”Kumar notes that experimental validation of their approach is another, and very important, challenge. “We decided to test our framework by first trying to predict nanocrystal structures that have already been observed experimentally. Next, we created a library of crystal structures – including those obtained experimentally – specifying the relevant experimental parameters, such as DNA linker ratio and the size of the DNA grafted nanoparticles. Then we ran the genetic algorithm for a desired crystal structure that has been observed experimentally, using the CCM as a forward model. We were pleased that the genetic algorithm correctly predicted the experimental parameters that were used in the formation of the observed structure.” Explore further Journal information: Proceedings of the National Academy of Sciences Citation: Express yourself: Scientists use genetic algorithm to design self-assembling ssDNA-grafted particles (2013, November 27) retrieved 18 August 2019 from https://phys.org/news/2013-11-scientists-genetic-algorithm-self-assembling-ssdna-grafted.html Using genetic algorithms to discover new nanostructured materials More information: Designing DNA-grafted particles that self-assemble into desired crystalline structures using the genetic algorithm, PNAS November 12, 2013 vol. 110 no. 46 18431-18435, doi:10.1073/pnas.1316533110Related: 1Nanoparticle Superlattice Engineering with DNA, Science 14 October 2011: Vol. 334 no. 6053 pp. 204-208, doi:10.1126/science.1210493 Srinivasan, the paper’s other co-author, acknowledges that currently the forward CCM model used in the GA framework has certain limitations. “It assumes complete DNA hybridization within the contact areas between two DNA-grafted particles as being the driving force behind self-assembly,” he explains. “In essence, this restricts the analysis to purely attractive interaction effects. To provide a more complete enthalpic picture, we plan on building repulsive interactions between the non-complementary ssDNA linkers on the nanoparticles.” Enthalpy is a measure of the total energy of a thermodynamic system. “Furthermore,” Srinivasan continues, “entropy also provides a constraint on the actual number of hybridized linkers within the nanoparticle interaction area, as well as a cost on the configuration of particles within the lattice – both of which are currently being built into the model. In addition, the current CCM does not always uniquely define a crystal structure.” For example, he illustrates, the CCM cannot distinguish between the structures of CuAu (a copper/gold alloy) and CsCl (cesium chloride), since in the unit cell both crystals have the same number of nearest neighbors and particle distribution. “This gives rise to degeneracies that we plan to address by further refining the interaction types within a crystal lattice.”

The announcement marks a move by 3M into nanowire based technology for touchscreen displays and away from the traditional indium tin oxide design. Copper nanowire films could lower touch screen, LED and solar cell costs Citation: 3M teams with Cambrios to produce silver nanowire ink for touch displays (2013, December 24) retrieved 18 August 2019 from https://phys.org/news/2013-12-3m-teams-cambrios-silver-nanowire.html Silver nanowire ink is, as its name implies, is a type of ink made out of nanowires—a nanowire is an elongated structure with a diameter on the order of a single nanometer. Thus, the ink that is made is a mixture of combined nanowires (and other materials)—and because they are made of silver in this instance, are highly conductive. Using them as an ink to cover a screen allows for creating a touch surface that doesn’t rely on other sensors to discriminate location—that makes them more easily used in a wider variety of applications.In the announcement, the two companies report that they will be jointly developing three types of screens based on silver nanowire technology, metal mesh and ITO sensor film. 3M also announced plans to ramp up production of touch screen manufacturing capacity over the next year to incorporate the new silver nanowire based screens.The new screens will be made using conductive silver nanowire ink which is patterned using a polyester base. The nanowire ink, the two firms report, is particularly transparent, has very good clarity and very little haze, making it ideal for devices that require a high degree of sharp, clear images. Also, screen resistance can be customized to suit the specifications of individual vendors which allows for varying response times.Also noted is that the new screens can be used for both small devices such as phones and tablets and large ones, such as big (touch) screen TVs—they can also be used in applications that require round surfaces or conformity to angles, giving them an edge over tin oxide designs.The announcement of an agreement between behemoth 3M and the much smaller Cambrios also suggests that the huge corporations is no longer content to wait for breakthroughs in its own lab and is now willing to forge partnerships with other smaller companies to develop leading edge touch-screen technology.
Scientists have known for some time that stem cells respond to their environment as they grow—those grown on hard material, such as glass or metal for example, are more amenable to growing into bone cells. In this new effort, the researchers sought to discover if changes to a stem cell brought about by environment are retained if the stem cell is moved to a different environment.To find out, the researchers used mesenchymal cells which are known to be able to grow into almost any human body part. They placed the stem cells on a stiff substrate then moved them to one less stiff over differing numbers of days. In so doing, they found that the longer the cells were left on the stiff substrate the more a protein connected to bone growth (RUNX2) was expressed. Conversely, cells that were first placed on a soft surface and subsequently moved to a hard surface demonstrated a tendency to develop either bone or adipogenic tendencies. In another experiment, the researchers applied the stem cells to a substrate coated with a phototunable hydrogel—it grows softer when exposed to light—using it allowed for changing the stiffness of the substrate without having to move the cells. Using this approach the team found that if the cells were allowed to grow on the gel in its stiff state, for just one day, switching to a soft state caused the expression of RUNX2 to cease immediately. When they allowed the cells to grow for ten days on the stiff base, however, before switching to a soft one, expression of RUNX2 continued for another ten days before finally ceasing. This shows, the researchers contend, that stem cells have a memory component that is not yet understood.The researchers note that their findings could be applied to other stem cell research areas such as cases where unintentional consequences may be arising in experiments due to the stiffness of the substrate in which they are being grown. It also raises the question of whether other environmental factors might be impacting cell growth and if so, if they have a memory component as well. (Phys.org) —A team of researchers working at the University of Colorado has found that human stem cells appear to remember the physical nature of the structure they were grown on, after being moved to a different substrate. In their paper published in the journal Nature Materials, the researchers describe how they grew human stem cells on different substrates. In so doing, they discovered that the stem cells continued to express certain proteins related to a substrate even after its hardness was changed.

Hunt/Wikipedia More information: Mechanical memory and dosing influence stem cell fate, Nature Materials (2014) DOI: 10.1038/nmat3889AbstractWe investigated whether stem cells remember past physical signals and whether these can be exploited to dose cells mechanically. We found that the activation of the Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding domain (TAZ) as well as the pre-osteogenic transcription factor RUNX2 in human mesenchymal stem cells (hMSCs) cultured on soft poly(ethylene glycol) (PEG) hydrogels (Young’s modulus E ~ 2 kPa) depended on previous culture time on stiff tissue culture polystyrene (TCPS; E ~ 3 GPa). In addition, mechanical dosing of hMSCs cultured on initially stiff (E ~ 10 kPa) and then soft (E ~ 2 kPa) phototunable PEG hydrogels resulted in either reversible or—above a threshold mechanical dose—irreversible activation of YAP/TAZ and RUNX2. We also found that increased mechanical dosing on supraphysiologically stiff TCPS biases hMSCs towards osteogenic differentiation. We conclude that stem cells possess mechanical memory—with YAP/TAZ acting as an intracellular mechanical rheostat—that stores information from past physical environments and influences the cells’ fate.

Since the beginning of time, art has acquired various forms. To some, it appears mundane, while to the discerning eye, it is a celebration of life and a channel for expression of the artist’s creative endeavours.For the renowned Delhi-based architect and artist Rohit Raj Mehndiratta, art is an exploration into unknown areas which allow him to express himself with unfettered freedom. The artist looks beyond the tangible, to extract the infinite out of the finite, though others may see these as weird shapes smeared together.

Rohit Raj said, “I am trying to capture the inner reality – it has no spatial limit or concept of time. It is constantly shifting from moment to moment and at the same time urges the consciousness to find stability in the outside, the ‘other’ space. I am playing with this dichotomy in my art: marking moments and their spiritual intensity.” Also Read – Over 2 hours screen time daily will make your kids impulsive(Un) Fettered represents the artist’s desire to give form to these inner-landscapes, their co-existence and conflict with the external world and to critique the idea of the timelessness of one’s inner reality. Raj plays with the concept of space inside oneself, its constant state of motion as it moves, moulds, fuses and contorts. He seeks to “(un) fetter” this space by representing moments of time. By doing this, he brings the spiritual and emotional, both conflating together, into the artistic realm, to be experienced by the viewer, in their moment of time. Thus, the artist urges consciousness to find stability in the outside – or the ‘other’ space through the inner realm. By playing with this dichotomy, through various artistic means, he captures the spatial intensity of moments – otherwise confined to the inner realm. The mediums chosen vary from pen-ink, photomontages to acrylic on canvas. The process involves emotive moments that translate into intense sketching or pen and ink work. His work also revolves around photographing aspects of the physical realm that evokes the inside. He is currently a visiting faculty at the Sushant School of Architecture. His academic and research interests in the domain of visual urban representations and politics of urban development have led to a photographic exhibition called ‘Placed Settings’ in New York, where he explored the idea of identity and the city through photography paper presentations in a number of international conferences and published paper in Sarai Reader 09. He recently co-edited a monograph titled “The Structure: Works of Mahendra Raj” published by Park Books, Zurich.

Kolkata: Housing Infrastructure Development Corporation (HIDCO) will celebrate the first day of Bengali New Year on April 15 by requesting the residents of New Town to set up rooftop gardens to grow organic vegetables.Growing flowers on the terrace is quite common but to grow vegetables is not so common and HIDCO has shortlisted five agencies that can help the residents to pursue their venture. Though many people have the desire to grow vegetables and fruits on the terrace but they lack expertise. The agencies short-listed by HIDCO have the proper expertise to grow vegetables on rooftops. The pots are set up in ways so that they do not put additional weight on the roof. The vegetables that will be grown on the terrace include coloured capsicum, broccoli among others. Organic vegetables are in high demand and no chemicals are used to grow them. It may be mentioned that HIDCO, along with an NGO, is growing organic vegetables at Swapno Bhor. Compost is used instead of chemical fertilisers. The senior citizens who are members of Swapno Bhor are supervising the project. HIDCO has chalked out a series of programmes to celebrate Poila Baisakh. As Kolkata Gate has become a grand hit, brunch will be available to greet those who will visit the restaurant. A roof counter has been opened at Rabindra Tirtha. Bauls will present folk songs at Eco Park’s Banglar Gram.

As a kid, hooking a huge fish is a right of passage. You get a picture for the scrapbook and an “atta boy” from your dad.One young fisherman didn’t get a chance for the photo op when he went pier fishing on a sunny day with his pops. A video recently posted online shows the young angler hooking a huge fish, when a giant alligator calmly cruises into the frame to swipe it off the line. Everyday he’s hustlin’.Tough day, kid. At least your video went viral:
Ohio State looked fine last night, despite what social media saidOhio State trailed 14-13 at halftime, on the road against Indiana last night, causing a predictable social media pile on that the Buckeyes were overrated, and had no shot to contend for a national title.The Buckeyes ended up blowing out the Hoosiers in the second half to win comfortably, and Colin feels as strongly about his prediction they will win the national championship as he did before the game.Ohio State has a re-tooled offense and young secondary, so it’s not shocking a bunch of teenagers didn’t come out firing on all cylinders, in what was the biggest home game in the history of Indiana football.Social media is a distorted reality, and making sweeping conclusions on a snap-by-snap basis is just dumb. The Buckeyes will be fine, despite what Twitter says. NFL players shouldn’t complain about Roger Goodell’s power since they gave it to himEzekiel Elliott awaits the results of the appeal of his six-game suspension, and many reports say it will likely be reduced. Many argue that six games was too harsh of a penalty given the circumstances, and that Roger Goodell is more dictator than commissioner.As often happens, players have vocally expressed outrage that Roger Goodell, alone, wields the power to unilaterally decide suspensions, rather than a more democratic way to levy punishment.Colin thinks it’s ludicrous for players to complain about Goodell’s power, since they approved it in the last collective bargaining negotiations. Additionally, it’s not like they weren’t aware of Goodell’s reputation for harsh punishment when they come into the league. His nickname is “The Sheriff” after all.The best option for NFL players is to not give him the chance to dish out punishment by not getting in compromising situations in the first place. Elliott is a prime example.
