Lucy belonged to genus Australopithecus and the species afarensis, but she also belonged to the the hominid family (hominidae) to which humans belong. Although humans are of the family hominidae, we are not of Lucy's genus or species. We are Homo sapiens. How then, can Lucy be our ancient ancestor if we belong to a different genus and species? It's because humans and Lucy share a taxonomy up to the point of genus and species; there are many shared characteristics, but there are differences and these differences place humans in our own genus and species.

Another mock bank note parodying the "shinplasters" of the 1837 panic. Such small-denomination notes were based on the division of the Spanish dollar, the dominant specie of the time. Hence they were issued in sums of 6 (more accurately 6 1/4), 25, 50, and 75 cents. These fractional notes proliferated during the Panic of 1837 with the emergency suspension of specie (i.e., money in coin) payments by New York banks on May 10 of that year. "Treasury Note" and "Fifty Cents Shin Plaster" (nos. 1837-9 and -11) also use the bank note format to comment on the dismal state of American finances. Unlike these, however, "Humbug Glory Bank" is actually the same size as a real note. The note is payable to "Tumble Bug Benton," Missouri senator and hard-money advocate Thomas Hart Benton, and is signed by "Cunning Reuben [Whitney, anti-Bank adviser to Jackson and Van Buren] Cash'r" and "Honest Amos [Kendall, Postmaster General and influential advisor to Van Buren] Pres't." It shows several coins with the head of Andrew Jackson at left, a jackass with the title "Roman Firmness," a hickory leaf (alluding to Jackson's nickname "Old Hickory"), and a vignette showing Jackson's hat, clay pipe, spectacles, hickory stick, and veto (of the 1832 bill to recharter the Bank of the United States) in a blaze of light. Above is a quote from Jackson's March 1837 farewell address to the American people, "I leave this great people prosperous and happy."|Copyrighted by Anthony Fleetwood, 1837.|Published at 89 Nassau Str.

Environmental issues are a concern of many, if not most, Americans. However, there is considerable disagreement on how such issues should be handled. Different people can interpret even a very general issue such as conservation very differently. Some believe that conservation means limiting the use of resources to allow a resource to last longer. Others see the conservation of resources as a way to maximize benefits to humans. This utilitarian approach to conservation policy, would place no value on saving endangered species that provide no direct benefit to humans. At the other extreme, some envision conservation as meaning the protection of resources without regard to profit or material benefit to humans. This view places the preservation as being of the utmost importance, and is sometimes viewed as elitist.
The hazards associated with convective systems present some of the most dangerous conditions encountered by aircraft and pose many challenges to aviation operations. When convection is forecast to develop, aviation forecasters are required to issue a series of warning messages and other meteorological aeronautical products to various members of the aviation community. This lesson teaches these forecasters how to produce the products, doing so in the context of a case study in which learners assume the role of aeronautical forecaster on duty at the airport in Niamey, Niger on a night when convection develops. The lesson is one of three aviation weather case studies developed by the ASMET team to improve aviation forecasting in Africa.
It's no secret that greenhouse gases warm the planet and that this has dire consequences for the environment whole islands swallowed up by rising seas, animal and plant species stressed by higher temperatures, and upsets in ecological interactions as populations move to cooler areas. However, carbon dioxide has another, less familiar environmental repercussion: making the Earth's oceans more acidic. Higher levels of carbon dioxide in the atmosphere mean that more carbon dioxide dissolves in the ocean. This dissolved carbon dioxide forms carbonic acid the same substance that helps give carbonated beverages their acidic kick. While this process isn't going to make the ocean fizzy anytime soon, it is introducing its own set of challenges for marine organisms like plankton and coral.
More than four million barrels of oil spilled into the Gulf of Mexico during the 87-day period following the explosion at the Deepwater Horizon drilling rig on April 20, 2010. The environmental and social effects of the Gulf Oil Spill will continue to draw the attention of educators for years to come as scientists continue to learn more about The Deepwater Horizon blowout and its impacts over time. Help teach your students about this event using PLT activities.

Our human society consists of many intertwined Large Scale Socio-Technical Systems (LSSTS), such as infrastructures, industrial networks, the financial systems etc. Environmental pressures created by these systems on EarthŰŞs carrying capacity are leading to exhaustion of natural resources, loss of habitats and biodiversity, and are causing a resource and climate crisis. To avoid this sustainability crisis, we urgently need to transform our production and consumption patterns. Given that we, as inhabitants of this planet, are part of a complex and integrated global system, where and how should we begin this transformation? And how can we also ensure that our transformation efforts will lead to a sustainable world? LSSTS and the ecosystems that they are embedded in are known to be Complex Adaptive Systems (CAS). According to John Holland CAS are "...a dynamic network of many agents (which may represent cells, species, individuals, firms, nations) acting in parallel, constantly acting and reacting to what the other agents are doing. The control of a CAS tends to be highly dispersed and decentralized. If there is to be any coherent behavior in the system, it will have to to arise from competition and cooperation among the agents themselves. The overall behavior of the system is the result of a huge number of decisions made every moment" by many individual agents. Understanding Complex Adaptive Systems requires tools that themselves are complex to create and understand. Shalizi defines Agent Based Modeling as "An agent is a persistent thing which has some state we find worth representing, and which interacts with other agents, mutually modifying each otherŰŞs states. The components of an agent-based model are a collection of agents and their states, the rules governing the interactions of the agents and the environment within which they live." This course will explore the theory of CAS and their main properties. It will also teach you how to work with Agent Based Models in order to model and understand CAS.
This collection focuses on a rapidly evolving field in which the study of both species-specific and ubiquitous aging mechanisms informs the biological process of aging. Yet the field is not without substantial controversy, differing views arise as we come to understand aging across model systems - from bacteria to humans.
In this Interactive Lecture Demonstration, students will predict the main issues that might be included in short French language videos treating topics such as endangered species, organic farming, the effect of aerosols on the environment, pollution and sustainable development. They will then view short videos on the topics and reflect on how their prior assumptions meshed with reality.
Commercial fishing nets often trap "unprofitable" animals in the process of catching target species. In this activity, students experience the difficulty that fishermen experience while trying to isolate a target species when a variety of sea animals are found in the area of interest. Then the class discusses the large magnitude of this problem. Students practice data acquisition and analysis skills by collecting data and processing it to deduce trends on target species distribution. They conclude by discussing how bycatch impacts their lives and whether or not it is an important environmental issue that needs attention. As an extension, students use their creativity and innovative skills to design nets or other methods, theoretically and/or through hands-on prototyping, that fisherman could use to help avoid bycatch.
Bycatch, the unintended capture of animals in commercial fishing gear, is a hot topic in marine conservation today. The surprisingly high level of bycatch about 25% of the entire global catch is responsible for the decline of hundreds of thousands of dolphins, whales, porpoises, seabirds and sea turtles each year. Through this curricular unit, students analyze the significance of bycatch in the global ecosystem and propose solutions to help reduce bycatch. They become familiar with current attempts to reduce the fishing mortality of these animals. Through the associated activities, the challenges faced today are reinforced and students are stimulated to brainstorm about possible engineering designs or policy changes that could reduce the magnitude of bycatch.
The major figures in American national politics in 1838 are gently satirized, each characterized as riding a favorite issue or "hobbyhorse." At the lead (far left) is President Martin Van Buren, riding a horse "Sub-Treasury," which he calls his "Old Hickory nag." The artist refers to Van Buren's independent treasury program, a system whereby federal funds were to be administered by revenue-collecting agencies or local "sub-treasuries" rather than by a national bank. The Independent Treasury Bill was perceived as an outgrowth of predecessor Jackson's anti-Bank program. Another hobbyhorse, "United States Bank" (center), is shared by Whig senators Henry Clay and Daniel Webster, leaders of congressional opposition to Jackson and Van Buren's respective fiscal agendas. Clay says, "Either you or I must get off Dan, for this horse wont carry double!" Webster responds, "Dash my Whig if I get off Hal!" Directly behind Van Buren Democratic Senator Thomas Hart Benton rides a horse "Specie Currency," an allusion to Benton's championing of hard money economics. Benton was identified with administration efforts to curb the use of currency in favor of "specie" or coin, and to increase the ratio of gold to silver in circulation. He says, "My Golden Poney carries more weight than any of them!" Behind Clay and Webster is South Carolina senator John C. Calhoun, advocate of state's rights and the driver of Southern nullification of the "Tariff of Abominations." On the right are William Henry Harrison, in military uniform and riding an "Anti-Masonic" hobby, and Massachusetts Congressman John Quincy Adams on his "Abolition" mount. Harrison's horse is named after the party which supported his 1836 bid for the Presidency. When he says, ". . . unless there is another Morgan abduction, I'm afraid he'll [the horse] lose his wind!" he alludes to the suspicious 1826 death of William Morgan (purportedly at the hands of Masons) which fueled considerable anti-Masonic sentiment in the United States. Adams laments, "This horse, instead of being my Topaz, is my Ebony." |Entd . . . 1838 by H.R. Robinson.|Printed & publd. by H.R.

Because small mammals are prey species, they do not take to intensive conditions of surgery and hospitalisation very readily. Those that are handled very frequently by their owners are more bonded with humans and better surgical subjects as a result. Rodents and rabbits are particularly susceptible to the surgical complications of dehydration (blood and fluid loss), core temperature depression, hypovolaemic shock, ileus and renal and respiratory depression.
Analytical chemistry spans nearly all areas of chemistry but involves the development of tools and methods to measure physical properties of substances and apply those techniques to the identification of their presence (qualitative analysis) and quantify the amount present (quantitative analysis) of species in a wide variety of settings.

Staphylococcus aureus (S. aureus) is the key organism for food poisoning due to massive production of heat stable exotoxins. The current study was attempted to investigate the effect of Mr. Trivedi’s biofield treatment on S. aureus. S. aureus (ATCC 25923) was divided into two parts, Group (Gr.) I: control and Gr. II: treatment. After biofield treatment, Gr. II was further subdivided into two parts, Gr. IIA and Gr. IIB. Gr. IIA was analyzed on day 10, while Gr. IIB was stored and analyzed on day 159 after revival (Study I). The revived sample (Gr. IIB) were retreated on day 159 (Study II), and divided into three separate tubes. Tube 1 was analyzed on day 5, likewise, tube 2 and 3 were analyzed on day 10 and 15, respectively. All the experimental parameters were studied using automated MicroScan Walk-Away® system. The 16S rDNA sequencing was carried out in Gr. IIA sample to correlate the phylogenetic relationship of S. aureus with other bacterial species. The antimicrobial susceptibility and minimum inhibitory concentration showed significant alteration i.e. 92.86% and 90.00% respectively in treated cells of S. aureus as compared to control. The biochemical reactions also showed the significant (35.71%) alteration in treated sample with respect to control. The biotype number and microbial species were substantially changed in Gr. IIA (767177; Staphylococcus cohnii subsp. urealyticum) on day 10, while only the biotype numbers were changed in rest of the treated samples as compared to control (307016; S. aureus). The 16S rDNA analysis showed that the identified strain in this experiment was S. aureus (GenBank Accession No.: L37597) after biofield treatment. However, the nearest homolog genus-species was found as Staphylococcus simiae (GenBank Accession No.: DQ127902). These results suggested that biofield treatment has a significant impact on S. aureus in lyophilized as well as revived state.
Shigellosis is a major public health burden in India and its neighboring countries due to infection of Shigella species. The current study was attempted to investigate the effect of biofield treatment on Shigella flexneri (S. flexneri) with respect of antimicrobial susceptibility assay, biochemical characteristics and biotyping. The American Type Culture Collection (ATCC 9199) strain of S. flexneri was used in this experiment. The study was conducted in revived and lyophilized state of S. flexneri. Both revived (Group; Gr. II) and lyophilized (Gr. III) strain of S. flexneri were subjected to Mr. Trivedi’s biofield treatment. Gr. II was assessed on day 5 and day 10, while Gr. III on day 10 after biofield treatment with respect to control (Gr. I). The antimicrobial susceptibility of S. flexneri showed 35% alteration in Gr. II on day 10 while no alteration were observed on day 5 (Gr. II) and in Gr. III as compared to control. The minimum inhibitory concentration (MIC) values of biofield treated S. flexneri also showed significant (46.88%) alteration in Gr. II on day 10 while no alteration were observed on day 5 (Gr. II) and in Gr. III as compared to control. It was observed that overall 24.24% biochemical reactions were altered in which 21.21% alteration was found in Gr. II on day 10 with respect to control. Moreover, biotype number was changed in Gr. II on day 10 with identification of new organism i.e. Edwardsiella tarda (40015042) as compared to untreated strain of Shigella species (40010000). The result suggested that biofield treatment has significant impact on S. flexneri in revived treated cells (Gr. II) on day 10 with respect to antimicrobial susceptibility, MIC, biochemical reactions pattern and biotyping.
Antimicrobial resistance is a global health issue in the developing countries. This study was carried out to evaluate the impact of Mr. Trivedi’s biofield energy treatment on multidrug resistant (MDR) clinical lab isolates (LSs) of Staphylococcus species viz. Staphylococcus haemolyticus (LS 18), Staphylococcus epidermidis (LS 21), and Staphylococcus aureus (LS 30). Each strain was divided into the two groups i.e.control and treated. The control and treated groups were analyzed for the antimicrobial susceptibility pattern, minimum inhibitory concentration (MIC), biochemical analysis and biotype number using MicroScan Walk-Away® system. The analysis was done on day 10 after biofield treatment and compared with the control group. The sensitivity of erythromycin was improved from resistant to susceptible, while levofloxacin sensitivity was also improved from intermediate to susceptible in LS 21 isolate. The MIC results showed a decrease in the concentrations of ceftriaxone, erythromycin, imipenem, and levofloxacin antimicrobials in LS 21 as compared to the control. Linezolid and vancomycin also showed decrease in MIC as compared to the control in LS 30. Overall, 20.69% antimicrobials showed decrease in MIC value out of the tested twenty-nine after biofield treatment in Staphylococcus species. The biochemical study showed a 25% alteration in biochemical reactions as compared to the control. A significant change was reported in biotype numbers for all the three strains of MDR Staphylococcus species after biofield treatment as compared to the respective control group. On the basis of changed biotype number (306366) after biofield treatment in LS 18, the new organism was identified as Staphylococcus simulans with respect to the control species i.e. Staphylococcus haemolyticus (302302). The control group of S. epidermidis and S. aureus showed biotype number as 303064 and 757153 respectively. After biofield treatment, LS 21 and LS 30 isolates showed altered biotype number as 307064 and 317153 respectively. Overall, results conclude that biofield treatment could be used as complementary and alternative treatment strategy against multidrug resistant strains of Staphylococcus species with improved sensitivity and reduced MIC values of antimicrobial.
Morganella morganii (M. morganii) is one of the important nosocomial pathogen associated with the urinary tract infections and bacteremia. The aim of this study was to evaluate the effect of Mr. Trivedi’s biofield energy treatment on M. morganii in the lyophilized as well as revived state for antimicrobial susceptibility pattern, biochemical characteristics, biotype number and genotype. M. morganii cells were procured from MicroBioLogics Inc., USA in sealed packs bearing the American Type Culture Collection (ATCC 25829) number and stored according to the recommended storage protocols until needed for experiments. M. morganii strain was divided into two groups, Group (Gr.) I: control and Gr. II: treated. Gr. II was further subdivided into two groups, Gr. IIA and Gr. IIB. Gr. IIA was analyzed on day 10, while Gr. IIB was stored and analyzed on day 142 (Study I). After retreatment on day 142, the sample (Study II) was divided into three separate tubes. First, second and third tube was further analyzed on day 5, 10 and 15 respectively. All experimental parameters were studied using the automated MicroScan Walk-Away® system. The 16S rDNA sequencing of lyophilized treated sample was carried out to correlate the phylogenetic relationship of M. morganii with other bacterial species. Antimicrobial susceptibility results showed 32.14% alterations, while minimum inhibitory concentration results showed 18.75% alterations of the tested antimicrobials. Biochemical study also showed altered positive reactions in nitrofurantoin and indole with respect to control. Biotype study showed alteration in Gr. IIB, study II, on day 15 (4005 1446) as compared to the control (4004 1446). 16S rDNA sequencing analysis showed similar results with the identified microbe as M. morganii (GenBank accession number: AB210972) having 80% identity of the gene sequencing data. Total 1507 base nucleotide of 16S rDNA gene sequences were analyzed by multiple alignments, while nearest homolog genus-species of M. morganii was found as Providencia rettgeri (accession number: AM040492). These results suggested that biofield treatment has a significant impact on M. morganii in lyophilized as well as revived state
Bacillary dysentery and acute gastroenteritis caused by infection of Shigella species are major public health burden in India and its neighboring countries. Emergence of antimicrobial resistance threatens to render current treatments ineffective. The current study was attempted to investigate the effect of biofield treatment on Shigella boydii (S. boydiii) with respect of antimicrobial susceptibility assay, biochemical characteristics and biotyping. The American Type Culture Collection (ATCC 9207) strain of S. boydiii was used in this experiment. The study was conducted in revived and lyophilized state of S. boydiii. Both revived (Group; Gr. II) and lyophilized (Gr. III) strain of S. boydiii were subjected to Mr. Trivedi’s biofield treatment. Gr. II was assessed on day 5 and day 10, while Gr. III on day 10 with respect to control (Gr. I). Sensitivity pattern of amoxicillin/k-clavulanate was improved from intermediate (I) to susceptible (S) with correspond to MIC value was also reduced by two folds (16/8 to ≤ 8/4 μg/mL) in both the treated groups as compared to control. The antimicrobial susceptibility of S. boydiii showed 15% alteration in Gr. II on day 5, while significant (40%) alteration was found on day 10 as compared to control. The MIC values of antimicrobials for S. boydiii also showed 12.50% alteration in Gr. II on day 5 while, significant alteration (59.38%) of minimum inhibitory concentration (MIC) value was found in Gr. II on day 10 as compared to control. It was observed that overall 69.70% biochemical reactions were changed in which 66.67% alteration was found in Gr. II on day 10 with respect to control. Moreover, biotype numbers were changed in all the treated groups without alteration of organism as compared to control. These results suggested that biofield treatment had significant impact on S. boydiii in Gr. II on day 10 with respect to antimicrobial susceptibility, MIC and biochemical reactions pattern.
Finding and eradicating invasive plants is a tough job that requires constant vigilance. County-scale maps that show where invasive plants are and where they have the potential to spread in the future are helping on-the-ground efforts to build the resilience of natural vegetation.
The osmotic controlled passage of polar water through fundamentally nonpolar biologic lipid bilayers (membranes) wasn't understood until the work of Peter Agre and Roderick MacKinnon on aquaporins resulting in the Nobel prize in Chemistry in 2003. We decided to examine conservation in aquaporins. A Google search provided us with both the PDB id (1h6i) of the human aquaporin A chain from RBCs, and a clearer understanding that the aquaprorins represent a related group of proteins present in multiple species. At http://www.rcsb.org/pdb/ we conducted an initial investigation of the structure of 1h6i. At consurf (http://consurf.tau.ac.il/) we were able to obtain the protein sequences for the best 20 matches in nearly FASTA form. After text editing we ran Clustalw and retrieved both rooted and unrooted trees. In the trees, it is easy to see the families of aquaporins (type 1, 2 etc; see tree.doc below).
Students create four-legged walking robots and measure how far they travel across different types of surfaces. They design and create "shoes" to add to the robots' feet and observe the effect of their modifications on the net distance traveled across the various surface types. This activity illustrates how the specialized locomotive features of different species help them to survive or thrive in their habitat environments. The activity is best as an enrichment tool that follows a lesson that introduces the concept of biological adaptation to students.
The purpose of this resource is to observe when selected bird species first arrive at your study site, and to count the numbers until few or none of these birds are seen. Students select a common and easily identifiable bird species in their region and observe when the bird species first arrives. Students use binoculars or telescopes to scan a study site and count how many they see. They continue to observe every other day until few or none of the selected species can be seen.

Enterobacter aerogenes (E. aerogenes) has been reported as the versatile opportunistic pathogen associated with the hospital infections worldwide. The aim of the study was to determine the impact of Mr. Trivedi’s biofield energy treatment on multidrug resistant clinical lab isolates (LSs) of E. aerogenes. The MDR isolates of E. aerogenes (i.e., LS 45 and LS 54) were divided into two groups, i.e., control and treated. Samples were analyzed for antimicrobial susceptibility pattern, minimum inhibitory concentration (MIC), biochemical study, and biotype number using MicroScan Walk-Away®system, on day 10 after the biofield treatment. The antimicrobial sensitivity assay showed 14.28% alteration out of twenty eight tested antimicrobials with respect to the control. The cefotetan sensitivity changed from intermediate (I) to inducible β-lactamase (IB), while piperacillin/tazobactam changed from resistant to IB in the treated LS 45. Improved sensitivity was reported in tetracycline, i.e., from I to susceptible (S) in LS 45, while chloramphenicol and tetracycline sensitivity changed from R to I in treated LS 54. Four-fold decrease in MIC value was reported in piperacillin/tazobactam, and two-fold decrease in cefotetan and tetracycline in the biofield treated LS 45 as compared to the control. MIC results showed an overall decreased MIC values in 12.50% tested antimicrobials such as chloramphenicol (16 μg/mL) and tetracycline (8 μg/mL) in LS 54. The biochemical study showed an overall 45.45% negative reaction in the tested biochemical in both the treated isolates as compared to the control. A change in biotype number was reported in MDR isolates (LS 45 and LS 54), while in LS 54, altered biotype number, i.e., 0406 0374 as compared to the control (7770 4376), with identification of the new species as Stenotrophomonas maltophilia with brown color as special characteristic. The study findings suggest that Mr. Trivedi’s biofield energy treatment on clinical MDR isolates of E. aerogenes has the significant effect on altering the sensitivity of antimicrobials, decreasing the MIC values, changed biochemical reactions, and biotype number.
At what point in evolutionary development does a group of individuals become two distinct species? This case addresses that fundamental question by asking students to decide whether apple maggot flies are distinct as a species from hawthorn maggot flies. In making their decision, students examine the different models of speciation and consider the primary forces that effect evolutionary change. Developed for an advanced undergraduate course in evolutionary biology, it would be appropriate for any biology course in which students are taught about the models of speciation. It could also be used in a general ecology course in which students consider the distribution and use of resources leading to niche specialization or in a genetics course if restrictions in gene flow are taught in the context of speciation.
The peripheral nervous system found in most domestic species can be segregated into three sub-systems; the sensory system, the somatic motor system and the autonomic system. The autonomic nervous system (ANS) regulates the internal environment of the body including factors such as body temperature, blood pressure and concentrations of many substances. The ANS is also responsible for mobilising the body's resources during stressful situations. The ANS controls gland cells, cardiac muscle cells and smooth muscle cells. Control of this nervous system is involuntary and regulation is via autonomic reflexes. The autonomic reflex arc system is very similar to that of the somatic motor system, i.e. there are sensory (afferent) nerve fibres, an information integration centre, motor (efferent) fibres and effector cells. Any levels of increased activity within the autonomic nervous system can result in both stimulation or inhibition of effector cells, although it is only the efferent part of the reflex arc that is actually considered autonomic.
About 70% of our planet is covered by oceans and seas: large, full of life and mysterious.
They are a source of food, way of transportation, oxygen producer, and more.
But the sea is in danger: overfishing, plastic waste, acidification, species extinction.
We need to better understand the marine life and deal with it in a sustainable way, because our life is closely linked to the sea. If it is sick, we cannot stay healthy.
