If you were curating a mixtape that might be heard by aliens billions of years from now - but definitely would be seen by your fellow Earthlings - what would you put on it? In 1977, two Voyager spacecraft launched from Cape Canaveral on a journey that would take them beyond our solar system. Affixed to the side of these two planetary explorers was the Voyager Golden Record — the ultimate mixtape of humanity — containing 27 pieces of music as well as pictures and sounds of Earth. But how did these selections get made? Nearly 50 years later, we're teaming up with our friends at the Smithsonian National Air and Space Museum's podcast, AirSpace, to explore what's on the record, how it got made, and its legacy.Learn more about AirSpace!

I will discuss Effective Field Theories that can originate from microscopic unitary theories, and their relation to moment theory. I will show that massive gravity, theories with isolated massive higher-spin particles, and theories with very irrelevant interactions, don't posses healthy UV completions, and I will show how Vector Meson Dominance follows from such first principles.

Can time symmetry in physics, combined with exceptional violations of the 2nd law of thermodynamics, and the “quantum handshake” transactional interpretation of Quantum mechanics, open up main stream physics to the possibility of retro-causation? Could it help to explain the many paradoxes left open in modern physics? and is there experimental evidence for it? Today we have the extraordinary possibility of retro-causation to get our heads around: the apparently impossible phenomenon of events in the present causing changes in the past, or future events having an effect in the present depending on how you want to look at it. Today we'll be approaching this topic via the context of time symmetry in physics. As far back as 1947, French quantum physicist Olivier Costa de Beauregard, began to question the usual interpretation of time in quantum mechanics, intuiting that something was missing from the model for the many paradoxes in Quantum Mechanics to remain unexplained. And then, with others get on board over the years, in the 80's, John G Kramer, agreed that the missing ingredient was found in time symmetry and he proposed a ‘quantum handshake' between the waves passing forward and backward in time at the moment of collapse; in this Transactional Interpretation of quantum mechanics, Kramer claimed he had solved the paradoxes. My guest today has put together this research, a re-interpretation of the 2nd law of thermodynamics based on violations where Entropy exceptionally does not hold, and theorisation about quantum correlates to consciousness to create a new theory of retro-causation, which he thinks can be tested. He is Daniel Sheehan, Author and Professor of Physics at the University of San Diego, specialist in plasma physics, violations of the 2nd Law thermodynamics and Retro-causation. He is the founder the Quantum Retro-causation symposia that met at The University of San Diego.

A combination of two checkpoint inhibitors used as neoadjuvant therapy for macroscopic, resectable Stage III melanoma brought a highly statistically significant improvement over the standard of care: surgery followed by checkpoint inhibition (therapeutic lymph node dissection followed by adjuvant therapy with nivolumab, pembrolizumab or, in BRAFmut melanoma, dabrafenib + trametinib). This research was reported from the ASCO 2024 Annual Meeting and highlighted the NADINA trial from the Netherlands. After his session at ASCO, the lead author of NADINA, Christian U. Blank, MD, PhD, from the Netherlands Cancer Institute and Antoni van Leeuwenhook Hospital, Amsterdam, the Netherlands, met up with Oncology Times reporter Peter Goodwin to discuss the findings.
Macroscopic Skin Lesions A thorough skin examination should be performed annually to assess for new or changing macroscopic skin lesions. It is critically important to be able to identify and describe normal and abnormal skin and to note your findings carefully, because a change in an existing skin lesion is the most common sign of skin cancer, including deadly ones like melanoma. In this discussion, we will describe the specific ways in which you document skin lesions, using a vocabulary that other clinicians will understand. After listening to this AudioBrick, you should be able to: Explain the importance of physical examination of the skin. Describe skin lesions, explaining and illustrating each of the following: size, type (eg, vesicle, bulla), color, configuration (eg, annular, targetoid, discoid), arrangement (eg, solitary, grouped, linear, reticular), and distribution and location.

今期行星酒馆,邀请到了两位外籍人士 Matt 和 Ling。 他们都曾定居中国,在这里度过大部分成年时光。几年间选择了离开的他们,在过去半年,先后回到中国短暂停留。借着两位朋友的「外宾」视角,我想聊聊重新踏上「故土」时经历的轶事和复杂的心情;也分享他们观察到的、这片土地所上发生的微妙变化。 为了让大家更为舒适地对谈,播客主要用英文录制。访谈的翻译版可在海外《行星酒馆》文字专栏找到。希望未来,我们也可以打破语言的隔阂,用同声传译地方式呈现跨语言的对话。 海外用户可在Patreon支持行星酒馆: https://www.patreon.com/planetspeakeasy 海内用户可在爱发电支持行星酒馆: https://www.afdian.net/a/planetspeakeasy In the 2021/22 academic year, there were a total of 211 American students studying in China. Just five years ago, the number stood at 11,639 — a reduction in scale of over fifty times. The steep decline in the number of U.S. students there is just the tip of the iceberg during this dynamic shift between the world's two superpowers. The departure of foreign companies, a drop of international tourists, and the increasingly polarized discourse about foreigners all contribute to this trend, resulting in an ongoing exodus of expats from a country that once seemed warm to them. Macroscopic consequences aside, there are tangible—and deeply painful—personal costs resulting from this rupture. Many of those in-betweeners were forced to leave behind the lives they had built, the languages they had picked up, the friendships they had forged, the communities they had cultivated, and an entire world they had settled into. On a broader scale, the land has become an increasingly opaque entity to the outside world, as those with firsthand experiences and the patience to navigate its intricacies are becoming growingly marginalized, both physically and culturally. Ironically, the only way to (kind of) start processing what we've lost over these few years is to start talking about our collective loss of understanding. In this inaugural English episode of Planet Speakeasy, two friends who once spent a significant portion of their adult lives in China shared a candid discussion about their recent "homecoming" trip: the familiar, the confusing, the surprising, and the beautiful, chaotic youth in an elusive "home" that we all miss so very much.

Dear Listeners, We are lucky to have Dr. Kevin back on the podcast. Micro and macroscopic hematurea are common incidental findings in primary care. They are often of a bening nature, but it is important to have a thorough method in investigating their differential so as not to miss rare but serious causes of bleeding […] The post Podcast 84: Dr. Kevin on Micro and Macroscopic Hematurea appeared first on Primary Medicine Podcast.
Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2022.12.20.521210v1?rss=1 Authors: Bin Khalid, I., Reifenstein, E. T., Auer, N., Kunz, L., Kempter, R. Abstract: Grid cells are neurons in the entorhinal cortex that play a key role in spatial navigation. When subjects navigate through spatial environments, grid cells exhibit firing fields that are arranged in a triangular grid pattern. As direct recordings of grid cells from the human brain are only rarely possible, functional magnetic resonance imaging (fMRI) studies proposed and described an indirect measure of entorhinal grid-cell activity, which is quantified as a hexadirectional modulation of fMRI activity as a function of the subject's movement direction. However, it still remains unclear how the activity of single grid cells is related to the sum activity of a population of grid cells, which may exhibit hexadirectional modulation and thus provide the basis for the hexadirectional modulation of entorhinal cortex activity measured with fMRI. Here, we thus performed numerical simulations and analytical calculations to better understand how the aggregated activity of many grid cells may be hexadirectionally modulated. Our simulations implemented three different hypotheses proposing that the hexadirectional modulation occurs because grid cells show head-direction tuning aligned with the grid axes; are subjected to repetition suppression; or exhibit a bias towards a particular grid phase offset. Our simulations demonstrate that all three hypotheses can, in principle, lead to a hexadirectional modulation of sum grid-cell activity. However, the magnitude of the hexadirectional modulation appears to depend considerably on the subject's navigation pattern and the exact biological properties of grid cells. Our results thus indicate that future fMRI studies could be designed to test which of the three hypotheses most likely accounts for the fMRI measure of grid cells. These findings also underline the importance of quantifying the biological properties of single grid cells in humans to further elucidate how hexadirectional modulations of fMRI activity may emerge.

Today Tiffany and Katja take a look at the cutting-edge new topic of fascia and pain. Pain is complex and recent research is showing just how relevant the fascial tissue is when we're looking at pain. In this episode, Katja shares the findings of the latest research on changes in fascia that can contribute to pain. The pair discuss the difference between pain in the fascia versus pain in muscle tissues and potential causes of fascial pain. They also touch on how other aspects such as the lymphatic system and lifestyle factors relate to inflammation, pain, and the fascial system. Listen in to learn about the anatomy and physiology of fascia and pain, how it happens, and ways you can potentially intervene.

Rich Stone, former international news editor at Science and current senior science editor at the Howard Hughes Medical Institute's Tangled Bank Studios, joins host Sarah Crespi to talk about concerning levels of fission reactions deep in an inaccessible area of the site of the 1986 Chernobyl nuclear disaster. Though nothing is likely to come of it anytime soon, scientists must decide what—if anything—they should do tamp down reactions in this hard-to-reach place. Also on this week's show, Shlomi Kotler, an assistant professor in the department of applied physics at the Hebrew University of Jerusalem, joins Sarah to discuss the quantum entanglement of macroscopic objects. This hallmark of quantum physics has been confined—up until now—to microscopic items like atoms, ions, and photons.

Macroscopic Skin Lesions A thorough skin examination should be performed annually to assess for new or changing macroscopic skin lesions. It is critically important to be able to identify and describe normal and abnormal skin and to note your findings carefully, because a change in an existing skin lesion is the most common sign of skin cancer, including deadly ones like melanoma. In this discussion, we will describe the specific ways in which you document skin lesions, using a vocabulary that other clinicians will understand. After listening to this AudioBrick, you should be able to: Explain the importance of physical examination of the skin. Describe skin lesions, explaining and illustrating each of the following: size, type (eg, vesicle, bulla), color, configuration (eg, annular, targetoid, discoid), arrangement (eg, solitary, grouped, linear, reticular), and distribution and location. You can also check out the original brick on Macroscopic Skin Lesions from our Musculoskeletal, Skin, and Connective Tissue collection, which is available for free.

Physics is both Classical and Quantum. Classical Physics involves studies of Macroscopic objects and very low speeds. Planets, Asteroids, Stars etc. On the other hand, Quantum Physics go deeper and smaller, with speeds approaching the one of light. We speak of particles, atoms and sub-atomic particles. And this is what we're studying today.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.10.15.341792v1?rss=1 Authors: Isık, M., Rustenburg, A. S., Rizzi, A., Gunner, M. R., Mobley, D. L., Chodera, J. D. Abstract: The prediction of acid dissociation constants (pKa) is a prerequisite for predicting many other properties of a small molecule, such as its protein-ligand binding affinity, distribution coefficient (logD), membrane permeability, and solubility. The prediction of each of these properties requires knowledge of the relevant protonation states and solution free energy penalties of each state. The SAMPL6 pKa Challenge was the first time that a separate challenge was conducted for evaluating pKa predictions as part of the Statistical Assessment of Modeling of Proteins and Ligands (SAMPL) exercises. This challenge was motivated by significant inaccuracies observed in prior physical property prediction challenges, such as the SAMPL5 logD Challenge, caused by protonation state and pKa prediction issues. The goal of the pKa challenge was to assess the performance of contemporary pKa prediction methods for drug-like molecules. The challenge set was composed of 24 small molecules that resembled fragments of kinase inhibitors, a number of which were multiprotic. Eleven research groups contributed blind predictions for a total of 37 pKa distinct prediction methods. In addition to blinded submissions, four widely used pKa prediction methods were included in the analysis as reference methods. Collecting both microscopic and macroscopic pKa predictions allowed in-depth evaluation of pKa prediction performance. This article highlights deficiencies of typical pKa prediction evaluation approaches when the distinction between microscopic and macroscopic pKas is ignored; in particular, we suggest more stringent evaluation criteria for microscopic and macroscopic pKa predictions guided by the available experimental data. Top-performing submissions for macroscopic pKa predictions achieved RMSE of 0.7-1.0 pKa units and included both quantum chemical and empirical approaches, where the total number of extra or missing macroscopic pKas predicted by these submissions were fewer than 8 for 24 molecules. A large number of submissions had RMSE spanning 1-3 pKa units. Molecules with sulfur-containing heterocycles or iodo and bromo groups were less accurately predicted on average considering all methods evaluated. For a subset of molecules, we utilized experimentally-determined microstates based on NMR to evaluate the dominant tautomer predictions for each macroscopic state. Prediction of dominant tautomers was a major source of error for microscopic pKa predictions, especially errors in charged tautomers. The degree of inaccuracy in pKa predictions observed in this challenge is detrimental to the protein-ligand binding affinity predictions due to errors in dominant protonation state predictions and the calculation of free energy corrections for multiple protonation states. Underestimation of ligand pKa by 1 unit can lead to errors in binding free energy errors up to 1.2 kcal/mol. The SAMPL6 pKa Challenge demonstrated the need for improving pKa prediction methods for drug-like molecules, especially for challenging moieties and multiprotic molecules.

Abstract: Loud noise-exposure generates tinnitus in both humans and animals. Macroscopic studies show that noise exposure affects the auditory cortex; however, cellular mechanisms of tinnitus generation are unclear. Here we compare membrane properties of layer 5 (L5) pyramidal cells (PCs) of the primary auditory cortex (A1) from control and noise-exposed mice. PCs were previously classified in type A or type B based on connectivity and firing properties. Our analysis based on a logistic regression model predicted that afterhyperpolatization and afterdepolarization following the injection of inward and outward current are enough to predict cell type and these features are preserved after noise trauma. One week after a noise-exposure (4-18kHz, 90dB, 1.5 hr, followed by 1.5hr silence) no passive membrane properties of type A or B PCs were altered but principal component analysis showed greater separation between control/noise-exposure recordings for type A neurons. When comparing individual firing properties, noise exposure differentially affected type A and B PC firing frequency in response to depolarizing current steps. Specifically, type A PCs decreased both initial and steady state firing frequency and type B PCs significantly increased steady state firing frequency following noise exposure. These results show that loud noise can cause distinct effects on type A and B L5 auditory cortex PCs one week following noise exposure. As the type A PC electrophysiological profile is correlated to corticofugal L5 neurons, and type B PCs correlate to contralateral projecting PCs these alterations could partially explain the reorganization of the auditory cortex observed in tinnitus patients.

In today's episode listeners will be treated to an interesting philosophical discussion. We explore concepts regarding the greater human organism and how it interacts with our energy infrastructure, large corporations, and how the continuum covering Maximum Human Potential to Maximum Human Regret should be applied to all decision making. A review of AC and DC electricity is also presented in conjunction with their use to optimize electrical consumption across the grid. We also explore electrical distribution, storage, and phasing, and load sourcing and shifting and caching options. Enjoy!

Abstract: Synchronous oscillations of neuronal populations support resting-state cortical activity. Recent studies indicate that resting-state functional connectivity is not static, but exhibits complex dynamics. The mechanisms underlying the complex dynamics of cortical activity have not been well characterised. Here, we directly apply singular value decomposition (SVD) in source-reconstructed electroencephalography (EEG) in order to characterise the dynamics of spatiotemporal patterns of resting-state functional connectivity. We found that changes in resting-state functional connectivity were associated with distinct complex topological features, ''Rich-Club organisation'', of the default mode network, salience network, and motor network. Rich-club topology of the salience network revealed greater functional connectivity between ventrolateral prefrontal cortex and anterior insula, whereas Rich-club topologies of the default mode networks revealed bilateral functional connectivity between fronto-parietal and posterior cortices. Spectral analysis of the dynamics underlying Rich-club organisations of these source-space network patterns revealed that resting-state cortical activity exhibit distinct dynamical regimes whose intrinsic expressions contain fast oscillations in the alpha-beta band and with the envelope-signal in the timescale of $

While quantum theory has been tested to an incredible degree on microscopic scales, quantum effects are seldom observed in our everyday macroscopic world. The curious results of applying quantum mechanics to macroscopic objects are perhaps best illustrated by Erwin Schrödinger's famous thought experiment, where a cat can be put into a superposition state of being both dead and alive. Obviously, these quantum predictions are in stark contradiction to our common experience. Even with plenty of theoretical explanations put forward to explain this discrepancy, a large number of questions about the frontier between the quantum and the classical world remain unanswered. To distinguish between classical and quantum behavior, two fundamental concepts inherent to classical physics have been established over the years: The world view of local realism limits the power of classical experiments to establish correlations over space, while the world view of macroscopic realism (or macrorealism) restricts temporal correlations. Necessary conditions for both world views have been formulated in the form of Bell and Leggett-Garg inequalities, and Bell inequalities have been shown to be violated by quantum mechanics through increasingly conclusive experiments. Furthermore, many challenging steps towards convincing violations of macrorealism have been taken in a number of recent experiments. In the first part of this thesis, conditions for macrorealism are analyzed in detail. Two necessary conditions for macrorealism, the original Leggett-Garg inequality and the recently proposed no-signaling in time condition, are presented. It is then shown that a combination of no-signaling in time conditions is not only necessary but also sufficient for the existence of a macrorealistic description. Finally, an operational formulation of no-signaling in time, in terms of positive-operator valued measurements and Hamiltonians, is derived. In the next part, we argue that these results lead to a suitable definition of classical behavior. In particular, we provide a formalism to judge the classicality of measurements and time evolutions. We then proceed to apply it to a number of exemplary measurement operators and Hamiltonians. Finally, we argue for the importance of spontaneously realized Hamiltonians in our intuition of classical behavior. Next, differences between local realism and macrorealism are analyzed. For this purpose, the probability polytopes for spatially and temporally separated experiments are compared, and a fundamental difference in the power of quantum mechanics to build both types of correlations is discovered. This result shows that Fine's theorem, which states that a set of Bell inequalities is necessary and sufficient for local realism, is not transferable to macrorealism. Thus, (Leggett-Garg) inequalities are in principle not well-suited for tests of macrorealism, as they can never form a necessary and sufficient condition, and unnecessarily restrict the violating parameter space. No-signaling in time is both better suited and more strongly motivated from the underlying physical theory. In the final part of this thesis, a concrete experimental setup for implementing quantum experiments with macroscopic objects is proposed. It consists of a superconducting micro-sphere in the Meißner state, which is levitated by magnetic fields. Through its expelled magnetic field, the sphere's center-of-mass motion couples to a superconducting quantum circuit. Properly tuned, ground state cooling can be realized, since the sphere's motion is extremely well isolated from the surrounding environment. This setup therefore is a promising candidate for the observation of quantum effects in macroscopic systems.

Peter Pickl (LMU) gives a talk at the MCMP Colloquium (10 June, 2015) titled "Explaining Macroscopic Systems from Microscopic Principles". Abstract: The revolutionary idea of the late 19th century that the physics of gases can be explained by the dynamics of small, point-like particles had a great influence on physics as well as mathematics and philosophy. This idea has changed our understanding of the physics of macroscopic systems significantly as well as the way we see our universe as a whole. The question of how the connection between the microscopic and the macroscopic world can be explained also arises in other fields, for example the life sciences. Answering this question might have a similar impact on the research in these fields. In the talk I will present recent techniques and results of our research group in deriving macroscopic evolution equations from microscopic principles for certain classical, quantum mechanical and biological systems.
Rainer Hegelmann (Bayreuth) gives a talk at the MCMP Colloquium (15 January, 2014) titled "Understanding epistemic grouping, networking and division of labour: What can simple macroscopic models do?". Abstract: In my talk I’ll start with a minimalistic model of opinion dynamics, the so-called bounded confidence model. Then I present stepwise extensions. In the end we have a model with cognitive division of labor and different epistemic groups, all of them engaged in networking of all sorts. Some of the groups are seeking for the truth or try to climb upwards in cliffy epistemic landscapes. Other groups simply follow the truth seekers and climbers. – As a result we get a simulator that allows, for instance, to analyse cost and benefits of networking and grouping, measured in terms of societal distance to the truth.
Jean Bricmont (Université catholique de Louvain) gives a talk at the 17th UK and European Meeting on the Foundations of Physics (29-31 July, 2013) titled "From the microscopic to the macroscopic world". Abstract: The derivation of the laws describing the macroscopic world from those governing the microscopic one is a very difficult problem. The root of the difficulty is sometimes seen as arising from the fact that the first set of laws are often time-irreversible, while the second ones are time-reversible. The goal of the talk will be to explain precisely these notions (macroscopic, microscopic, (ir)reversibility) and why this difference does not constitute an insuperable difficulty. We will also discuss the role of probability in the derivation of the macroscopic laws from the microscopic ones and criticize several misleading attempts at justifying this derivation.

After myocardial infarction, the implantation of stem cell seeded scaffolds on the ischemic zone represents a promising strategy for restoration of heart function. However, mechanical integrity and functionality of tissue engineered constructs need to be determined prior to implantation. Therefore, in this study a novel pulsatile bioreactor mimicking the myocardial contraction was developed to analyze the behavior of mesenchymal stem cells derived from umbilical cord tissue (UCMSC) colonized on titanium-coated polytetrafluorethylene scaffolds to friction stress. The design of the bioreactor enables a simple handling and defined mechanical forces on three seeded scaffolds at physiological conditions. The compact system made of acrylic glass, Teflon®, silicone, and stainless steel allows the comparison of different media, cells and scaffolds. The bioreactor can be gas sterilized and actuated in a standard incubator. Macroscopic observations and pressure-measurements showed a uniformly sinusoidal pulsation, indicating that the bioreactor performed well. Preliminary experiments to determine the adherence rate and morphology of UCMSC after mechanical loadings showed an almost confluent cellular coating without damage on the cell surface. In summary, the bioreactor is an adequate tool for the mechanical stress of seeded scaffolds and offers dynamic stimuli for pre-conditioning of cardiac tissue engineered constructs in vitro.

Background: Between 10,000 and 12,000 cases of imported malaria are notified in the European Union each year. Despite an excellent health care system, fatalities do occur. In case of advanced autolysis, the post-mortem diagnostic is impaired. Quicker diagnosis could be achieved by using rapid diagnostic malaria tests. Methods: In order to evaluate different methods for the post-mortem diagnosis of Plasmodium falciparum malaria in non-immunes, a study was performed on the basis of forensic autopsies of corpses examined at variable intervals after death in five cases of fatal malaria (with an interval of four hours to five days), and in 20 cases of deaths unrelated to malaria. Detection of parasite DNA by PCR and an immunochromatographic test (ICT) based upon the detection of P. falciparum histidine-rich protein 2 (PfHRP2) were compared with the results of microscopic examination of smears from cadaveric blood, histopathological findings, and autopsy results. Results: In all cases of fatal malaria, post-mortem findings were unsuspicious for the final diagnosis, and autoptic investigations, including histopathology, were only performed because of additional information by police officers and neighbours. Macroscopic findings during autopsy were unspecific. Histopathology confirmed sequestration of erythrocytes and pigment in macrophages in most organs in four patients (not evaluable in one patient due to autolysis). Microscopy of cadaveric blood smears revealed remnants of intraerythrocytic parasites, and was compromised or impossible due to autolysis in two cases. PCR and ICT performed with cadaveric blood were positive in all malaria patients and negative in all controls. Conclusion: In non-immune fatalities with unclear anamnesis, ICT can be recommended as a sensitive and specific tool for post-mortem malaria diagnosis, which is easier and faster than microscopy, and also applicable when microscopic examination is impossible due to autolysis. PCR is more expensive and time-consuming, but may be used as confirmatory test. In highly endemic areas where asymptomatic parasitaemia is common, confirmation of the diagnosis of malaria as the cause of death has to rely on histopathological findings.
It is vital not to take our most fundamental physical theories for granted. For example, researchers have looked for deviations from the gravitational inverse square law at very small sub-micron length scales. Similarly, one can ask what predictions of quantum mechanics might break down in untested regimes. Since the classical world is macroscopic and the quantum world is microscopic, a natural place to test quantum mechanics is in mesoscopic physics. Macroscopic superposition is a largely untested mesoscopic prediction of quantum mechanics. An excellent candidate for macroscopic superposition states, also called Cat (or NOON) States after Schrodinger's famous gedanken experiment, is a Bose-Einstein condensate in a double well. Mathematically, this is a fifty year old quantum many body problem. The experimental context of Bose-Einstein condensates gives one hope to observe the first truly large scale Cat States of matter. We show that Bose-Einstein condensates require two new energy scales. We introduce the role of the dimensionality of each well. We demonstrate that the many body wavefunction serves to protect Cat States from decoherence. Finally, we present a practical scheme for dynamic realization of such states. Presented October 12, 2007.

Peace, Ecology and the Human Scale: Leopold Kohr's Idea of Small Societies being Up-to-Date
An equilibrium phase belonging to the family of bilayer liposomes in ternary mixtures of dimyristoylphosphatidylcholine (DMPC), water, and geraniol (a biological alcohol derived from oil-soluble vitamins that acts as a cosurfactant) has been identified. Electron and optical microscopy reveal the phase, labeled Ltv, to be composed of highly entangled tubular vesicles. In situ x-ray diffraction confirms that the tubule walls are multilamellar with the lipids in the chain-melted state. Macroscopic observations show that the Ltv phase coexists with the well-known L4 phase of spherical vesicles and a bulk L alpha phase. However, the defining characteristic of the Ltv phase is the Weissenberg rod climbing effect under shear, which results from its polymer-like entangled microstructure.
Abstract Purple bacterial aggregates found in tidal pools of Great Sippewissett Salt Marsh (Falmouth, Cape Cod, MA) were investigated in order to elucidate the ecological significance of cell aggregation. Purple sulfur bacteria were the dominant microorganisms in the aggregates which also contained diatoms and a high number of small rod-shaped bacteria. Urea in concentrations of ≥ 1 M caused disintegration of the aggregates while proteolytic enzymes, surfactants or chaotropic agents did not exhibit this effect. This suggests that polysaccharides in the embedding slime matrix stabilize the aggregate structure. In addition cell surface hydrophobicity is involved in aggregate formation. The concentration of dissolved oxygen decreased rapidly below the surface of aggregates while sulfide was not detected. The apparent respiration rate in the aggregates was high when the purple sulfur bacteria contained intracellular sulfur globules. In the presence of DCMU, respiration remained light-inhibited. Light inhibition disappeared in the presence of KCN. These results demonstrated that respiration in the aggregates is due mainly to purple sulfur bacteria. The concentration of bacteriochlorophyll (Bchl) a in the aggregates (0.205 mg Bchl a cm−3) was much higher than in the pool sediments but comparable to concentrations in microbial mats of adjacent sand flats. Purple aggregates may therefore originate in the microbial mats rather than in the pools themselves. Rapid sedimentation and high respiration rates of Chromatiaceae in the aggregates would prevent the inhibition of Bchl synthesis if aggregates were lifted off the sediment and up into the oxic pool water by tidal currents.
