A mongoose on a leash, a colorful pelican and various bats are just a few of the rare animal drawings revealed in a new survey of a group of 4,000-year-old tombs in Egypt. The tombs are located at the Beni Hassan cemetery and were excavated and detailed in a publication over a century ago by archaeologist Percy Newberry and his colleagues, wrote Linda Evans, a senior lecturer at Macquarie University in Australia, in an article published recently in the Journal of the American Research Center in Egypt. Now, Evans and other archaeologists at Macquarie University's Australian Centre for Egyptology are re-surveying the tombs using modern-day technology. Recently, an Egyptian antiquities ministry team also conserved and cleaned the tombs. [See Photos of the Ancient Egyptian Tombs and Colorful Drawings] The conservation and recording has "revealed many scenes not found in Newberry's reports," wrote Evans. In addition, the new work has identified creatures in the drawings that Newberry had been uncertain about. For instance, Newberry noted only the possible existence of a leashed Egyptian mongoose, a burrowing animal with a speckled gray coat, writing down the identification as a suggestion. Some Egyptologists who reviewed his reports thought the identification was incorrect, Evans noted. "No other images of leashed mongooses are known in Egyptian art," Evans wrote. Evans' team determined that the animal is "morphologically identical" to the Egyptian mongoose, wrote Evans, noting that the animal is also clearly depicted on a leash. "The animal clearly sports a gray collar that tapers to join a long, gray leash, which is held in the left hand of a bearer, who also holds the leash of a spotted hunting dog situated below the mongoose," Evans said. The tomb belonged to Baqet I, a nomarch or provincial governor, who ruled during the 11th Dynasty. The researchers said they don't know why an ancient Egyptian artist drew a leashed mongoose on Baqet I's tomb. "While mongooses have never been fully domesticated — that is, subjected to controlled breeding — some cultures have chosen to keep the animals as pets in order to control unwanted pests, such as snakes, rats and mice," Evans wrote. The leashed mongoose shown on the tomb may have been used to scare birds so that they would fly out of the bush, making it easier for Egyptian hunters (who are depicted near the mongoose) to hunt them, according to Evans. A wall on another tomb, this one belonging to another 11th Dynasty nomarch, Baqet II, is decorated with an image of a pelican, its colors still preserved despite the passage of 4,000 years. Newberry never saw or at least never recorded the pelican, Evans noted in the journal article. [In Photos: Ancient Egyptian Coffin with 'Odd' Art] Pelicans "are rarely encountered in Egyptian art," though three species of pelican are known to pass over or winter in Egypt, Newberry wrote. The image "shows awareness of subtle behavior details," Evans added, noting that the artist depicted the bird holding its feet at an "unusually abrupt angle," in what appears to be an attempt to show a movement that pelicans are known to make. "When lifting off from the water, pelicans first hop across the surface for a number of meters, while simultaneously flapping their wings, thrusting their feet forward and back in unison in order to gain both lift and momentum," Evans wrote. The pelican drawn on the tomb appears to be in "midhop as it becomes airborne," she added. The researchers are recording and analyzing additional creatures depicted at the site, Evans said. In one tomb, the team found batdrawings that Newberry was not aware of. "Representations of bats are extremely rare" in ancient Egyptian art, Evans told Live Science in an email. The team is analyzing the bat images, which will be described in a future journal article, Evans said. The researchers said they aren't sure why so many animals, especially birds, are shown in the tombs at Beni Hassan. One painting, for instance, shows no fewer than 29 birds and three bats Evans said. "The striking preponderance of birds at the site may indicate a special role for the animals in the lives of the local inhabitants, or perhaps the region once attracted an unusual variety of birds, possibly serving as a stopover for migratory species," Evans wrote in the journal article, adding in an email that the "climate was probably somewhat milder than modern-day Egypt — not as hot and dry."

Integrons are versatile gene acquisition systems commonly found in bacterial genomes. They are ancient elements that are a hot spot for genomic complexity, generating phenotypic diversity and shaping adaptive responses. In recent times, they have had a major role in the acquisition, expression, and dissemination of antibiotic resistance genes. Assessing the ongoing threats posed by integrons requires an understanding of their origins and evolutionary history. This review examines the functions and activities of integrons before the antibiotic era. It shows how antibiotic use selected particular integrons from among the environmental pool of these elements, such that integrons carrying resistance genes are now present in the majority of Gram-negative pathogens. Finally, it examines the potential consequences of widespread pollution with the novel integrons that have been assembled via the agency of human antibiotic use and speculates on the potential uses of integrons as platforms for biotechnology.

The widespread use and abuse of antibiotic therapy has evolutionary and ecological consequences, some of which are only just beginning to be examined. One well known consequence is the fixation of mutations and lateral gene transfer (LGT) events that confer antibiotic resistance. Sequential selection events, driven by different classes of antibiotics, have resulted in the assembly of diverse resistance determinants and mobile DNAs into novel genetic elements of ever-growing complexity and flexibility. These novel plasmids, integrons, and genomic islands have now become fixed at high frequency in diverse cell lineages by human antibiotic use. Consequently they can be regarded as xenogenetic pollutants, analogous to xenobiotic compounds, but with the critical distinction that they replicate rather than degrade when released to pollute natural environments. Antibiotics themselves must also be regarded as pollutants, since human production overwhelms natural synthesis, and a major proportion of ingested antibiotic is excreted unchanged into waste streams. Such antibiotic pollutants have non-target effects, raising the general rates of mutation, recombination, and LGT in all the microbiome, and simultaneously providing the selective force to fix such changes. This has the consequence of recruiting more genes into the resistome and mobilome, and of increasing the overlap between these two components of microbial genomes. Thus the human use and environmental release of antibiotics is having second order effects on the microbial world, because these small molecules act as drivers of bacterial evolution. Continued pollution with both xenogenetic elements and the selective agents that fix such elements in populations has potentially adverse consequences for human welfare. © 2013 Gillings.

The initial (200-175 Ma) breakup of Pangea was marked by the emplacement of the Large Igneous Provinces (LIPs) of Karoo-Ferrar-SE Australia (KFS) in the back-arc of Panthalassan subduction and by the Central Atlantic Magmatic Province (CAMP) between Africa and the Americas. Seafloor spreading 190-180. Ma (Stage 1) about the CAMP split Pangea into northern (Laurasia) and southern (Gondwanaland) parts. Subsequent stages at 167 Ma (2), 147 Ma (3), 130 Ma (4), 118 Ma (5), and 83 Ma (6) split conjugate Africa, South America, India, Australia, and Zealandia from Antarctica. Here I review the reconstruction of Antarctica in Gondwanaland. First, seafloor spreading is unwound to re-unite the continent-ocean boundaries (COBs), then the extended (rifted) crust about the suture is restored to its original thickness. A comprehensive review of the U-Pb zircon geochronology of the reconstructed margins of Antarctica and its conjugates shows that certain coeval structures are aligned across the suture. Cross structures of high-order spatial continuity and age correlation are the Lambert-Mahanadi Rift, Pranhita-Godavari-Robert Glacier trend, Gawler-Adélie Craton, and western part of the Gondwanide Fold Belt. Cross structures of high-order age correlation but low structural continuity or alignment are, from Africa to Antarctica, the East African-Antarctic Orogen, the Natal and Maud Belts, the Umkondo Group-Ritscherflya Supergroup and LIP, and the Kalahari-Grunehogna Craton; from Antarctica to Zealandia, the Ross-Western and Amundsen-Eastern Provinces; and from Africa through Antarctica to Australia the KFS LIP. © 2011 Elsevier B.V.

The brain binds inputs from multiple senses to enhance our ability to identify key events in the environment. Understanding this process is based mainly on data from the major senses (vision and audition), yet compelling examples of binding occur in other domains. When we eat, in fact taste, smell, and touch combine to form flavor. This process can be so complete that most people fail to recognize that smell contributes to flavor. The flavor percept has other features: (a) it feels located in the mouth, even though smell is detected in the nose and taste on the tongue, and (b) it feels continuous, yet smell is delivered in pulses to the nose during eating. Furthermore, tastes can modify smell perception and vice versa. Current explanations of these binding-related phenomena are explored. Preattentive processing provides a well-supported account of taste-to-tongue binding. Learning between taste and smell can explain perceptual interactions between these senses and perhaps localization of smell to the mouth. Attentional processes may also be important, especially given their role in binding the major senses. Two are specifically examined. One claims that the failure to recognize smell's role in flavor stems from the role of involuntary attention's "defaulting" to the mouth and taste (i.e., binding by ignoring). Another claims that taste and smell form a common attentional channel in the mouth, in effect becoming one sense. Except for preattentive processing, the mechanisms involved in flavor binding differ markedly from those proposed for the major senses. This distinction may result from functional differences, with flavor supporting future food choice but not current identification. © 2013 American Psychological Association.

Schizophrenia Bulletin | Year: 2012
Progress in identifying the neural correlates of auditory verbal hallucinations (AVHs) experienced by patients with schizophrenia has not fulfilled its promise to lead to new methods of treatments. Given the existence of a large number of such patients who have AVHs that are refractory to traditional treatments, there is the urgent need for the development of new effective interventions. This article proposes that the technique of neurofeedback may be an appropriate method to allow the translation of pure research findings from AVH-research into a clinical intervention. Neurofeedback is a method through which individuals can self-regulate their neural activity in specific neural regions/frequencies, following operant conditioning of their intentional manipulation of visually presented real-time feedback of their neural activity. Four empirically testable hypotheses are proposed as to how neurofeedback may be employed to therapeutic effect in patients with AVHs. © 2012 The Author.

Background: There are few evaluations of very early intervention for the prevention of internalising disorders and those that exist generally evaluate outcomes to a maximum of 12 months. The current study evaluated the very long term effects (11 years) of a brief internalising prevention program presented to parents of preschool aged children. Methods: The original sample comprised 146 preschool-aged children who scored high on measures of inhibited temperament. Half of the parents were given a brief educational program (six-sessions) to assist them to help their children reduce anxiousness. Over 70% of the original sample (n = 103) was assessed for the current study, which occurred when the sample was approximately 15 years. They were assessed on current diagnoses of anxiety and depression, as well as symptoms of anxiety, depression, negative thoughts, and life interference. Results: Compared with controls, girls whose parents had been through the early intervention program showed significantly fewer internalising disorders, maternally reported anxiety symptoms and self-reported life interference, and trends toward lower self-reported anxiety symptoms and self reported thoughts of loss and failure. Boys showed few differences. Conclusions: A brief early intervention program delivered to parents of preschool-aged children who are at risk for later internalising distress shows lasting benefits for girls into the high-risk period of middle adolescence. Given the low costs associated with this program, these results show promise for strong public health benefits. © 2013 The Authors.

The concept of the sediment delivery problem was introduced into the literature in 1983 by Des Walling. This concept describes how only a fraction of sediment eroded within a catchment will reach the basin outlet and be represented as sediment yield, and that sediment storage mechanisms operating within a catchment explain this discrepancy. Since this paper was published, geomorphologists have been examining in great detail the fate of sediment eroded from the landsurface, and the pathways and timeframes of sediment transport and storage in catchments. However, to fully understand the internal dynamics of sediment flux requires a 'fresh look at the sediment delivery problem'. A framework is required that can incorporate the various processes involved in sediment movement from source areas through a basin to its outlet, and can take account of the spatial distribution of, and timeframes over which, these processes operate. This paper presents a conceptual framework for analysis of catchment (dis)connectivity that incorporates both spatial and temporal variability in the operation of the sediment cascade. This approach examines where blockages occur to disrupt these longitudinal, lateral and vertical linkages in catchments. Depending on the position of blockages (termed buffers, barriers and blankets), and their sediment residence time, various parts of a catchment may be actively contributing sediment to the sediment cascade and be switched on, or inactive and switched off. This paper discusses how such a framework can be used to model response times to disturbance and explain the manifestation of geomorphic change in catchments. The paper then highlights challenges geomorphologists face in applying such a framework to understand the internal dynamics of the catchment sediment cascades, and forecast how environmental change might affect the operation of sediment fluxes into the future. © 2012 John Wiley & Sons, Ltd.
