The drake equation revisited

In the almost half century since the Drake Equation was first conceived, a number of profound discoveries have been made that require each of the seven variables of this equation to be reconsidered. The discovery of hydrothermal vents on the ocean floor, for example, as well as the ever-increasing extreme conditions in which life is found on Earth, suggest a much wider range of possible extraterrestrial habitats. The growing consensus that life originated very early in Earth's history also supports this suggestion. The discovery of exoplanets with a wide range of host star types, and attendant habitable zones, suggests that life may be possible in planetary systems with stars quite unlike our Sun. Stellar evolution also plays an important part in that habitable zones are mobile. The increasing brightness of our Sun over the next few billion years, will place the Earth well outside the present habitable zone, but will then encompass Mars, giving rise to the notion that some Drake Equation variables, such as the fraction of planets on which life emerges, may have multiple values.

Body Count Casualty Figures after 10 Years of the “War on Terror” Iraq Afghanistan Pakistan Four Million Muslims Killed in US-NATO Wars A March report by Physicians for Social Responsibility calculates the body count of the Iraq War at around 1.3 million, and possibly as many as 2 million. However, the numbers of those killed in Middle Eastern wars could be much higher. The actual death toll could reach as high as 4 million if one includes not just those killed in the wars in Iraq and Afghanistan, but also the victims of the sanctions against Iraq, which left about 1.7 million more dead, half of them children, according to figures from the United Nations. In the wars that followed in Iraq and Afghanistan, the U.S. not only killed millions, but systematically destroyed the infrastructure necessary for healthy, prosperous life in those countries, then used rebuilding efforts as opportunities for profit, rather than to benefit the occupied populations. To further add to the genocidal pattern of behavior, there is ample evidence of torture and persistent rumors of sexual assault from the aftermath of Iraq’s fall. It appears likely the U.S. has contributed to further destabilization and death in the region by supporting the rise of the self-declared Islamic State of Iraq and Syria by arming rebel groups on all sides of the conflict.

Michael J. W. Hall, Dirk-André Deckert, and Howard M. Wiseman ABSTRACT We investigate whether quantum theory can be understood as the continuum limit of a mechanical theory, in which there is a huge, but finite, number of classical “worlds,” and quantum effects arise solely from a universal interaction between these worlds, without reference to any wave function. Here, a “world” means an entire universe with well-defined properties, determined by the classical configuration of its particles and fields. In our approach, each world evolves deterministically, probabilities arise due to ignorance as to which world a given observer occupies, and we argue that in the limit of infinitely many worlds the wave function can be recovered (as a secondary object) from the motion of these worlds. We introduce a simple model of such a “many interacting worlds” approach and show that it can reproduce some generic quantum phenomena—such as Ehrenfest’s theorem, wave packet spreading, barrier tunneling, and zero-point energy—as a direct consequence of mutual repulsion between worlds. Finally, we perform numerical simulations using our approach. We demonstrate, first, that it can be used to calculate quantum ground states, and second, that it is capable of reproducing, at least qualitatively, the double-slit interference phenomenon.

Government agencies have long employed entertainment industry liaisons to work with Hollywood in order to improve their public image. For instance, the Federal Bureau of Investigation established its entertainment office in the 1930s and has used its influence to bolster the image of the bureau in radio programs, films and television shows such as G-Men (1935), The Untouchables (1959–1963), The FBI Story (1959), and The F.B.I. (1965–1979). In 1947, the Department of Defense established its first entertainment industry liaison, and now, the Army, the Navy, the Air Force, the Marine Corps, the Department of Homeland Security, the Secret Service, and the US Coast Guard all have Motion Picture and Television Offices or official assistants to the media on their payroll. Even government centers are now working with Tinsel Town, as evidenced by Hollywood, Health, and Society—a program associated with the University of Southern California’s Annenberg Norman Lear Center and funded in part by the Center for Disease Control and the National Institute of Health to provide the entertainment industry with information for health-related story lines

The Search for the Manchurian Candidate: Marks' award-winning 1979 book, The Search for the Manchurian Candidate describes a wide range of CIA activities during the Cold War, including unethical drug experiments in the context of a mind-control and chemical interrogation research program. The book is based on 15,000 pages of CIA documents obtained under the Freedom of Information Act and many interviews, including those with retired members of the psychological division of the CIA, and the book describes some of the work of psychologists in this effort with a whole chapter on the Personality Assessment System. A 'Manchurian Candidate' is an unwitting assassin brainwashed and programmed to kill. In this book, former State Department officer John Marks tells the explosive story of the CIA's highly secret program of experiments in mind control. His curiosity first aroused by information on a puzzling suicide. Marks worked from thousands of pages of newly released documents as well as interviews and behavioral science studies, producing a book that 'accomplished what two Senate committees could not' (Senator Edward Kennedy).

Prof Bernard Carr Professor of Mathematics and Astronomy School of Physics and Astronomy Queen Mary, University of London Astronomer and mathematician Bernard Carr theorizes that many of the phenomena we experience but cannot explain within the physical laws of this dimension actually occur in other dimensions. Albert Einstein stated that there are at least four dimensions. The fourth dimension is time, or spacetime, since Einstein said space and time cannot be separated. In modern physics, theories about the existence of up to 11 dimensions and the possibility of more have gained traction. Carr, a professor of mathematics and astronomy at Queen Mary University of London, says our consciousness interacts with another dimension. Furthermore, the multi-dimensional universe he envisions has a hierarchical structure. We are at the lowest-level dimension. “The model resolves well-known philosophical problems concerning the relationship between matter and mind, elucidates the nature of time, and provides an ontological framework for the interpretation of phenomena such as apparitions, OBEs [out-of-body experiences], NDEs [near-death-experiences], and dreams,” he wrote in a conference abstract. Carr reasons that our physical sensors only show us a 3-dimensional universe, though there are actually at least four dimensions. What exists in the higher dimensions are entities we cannot touch with our physical sensors. He said that such entities must still have a type of space to exist in. “The only non-physical entities in the universe of which we have any experience are mental ones, and … the existence of paranormal phenomena suggests that mental entities have to exist in some sort of space,” Carr wrote. The other-dimensional space we enter in dreams overlaps with the space where memory exists. Carr says telepathy signals a communal mental space and clairvoyance also contains a physical space. “Non-physical percepts have attributes of externality,” he wrote in his book “Matter, Mind, and Higher Dimensions.” He builds on previous theories, including the Kaluza–Klein theory, which unifies the fundamental forces of gravitation and electromagnetism. The Kaluza–Klein theory also envisions a 5-dimensional space. In “M-theory,” there are 11 dimensions. In superstring theory, there are 10. Carr understands this as a 4-dimensional “external” space—meaning these are the four dimensions in Einstein’s relativity theory—and a 6- or 7-dimensional “internal” space—meaning these dimensions relate to psychic and other “intangible” phenomena.

Este artigo apresenta uma reflexão em torno da aceleração tecnológica atualmente em curso, utilizando o viés da IA como fio condutor, na tentativa de identificar tendências, implicações e perspectivas que poderão se concretizar no curto prazo, influindo, talvez radicalmente, no próprio futuro da humanidade. A atual escalada do desenvolvimento tecnológico coloca em bases concretas a perspectiva de realização do que tecnicamente está sendo chamado de Superinteligência Artificial (SIA), uma forma de inteligência muito superior a do ser humano em todos os sentidos. A possibilidade do desenvolvimento da SIA impõe, talvez pela primeira vez, em termos reais, a questão de uma tecnologia ser capaz de efetivamente “posicionar-se” contra a humanidade, com conseqüências imprevisíveis. Torna-se então necessário ampliar o debate em torno do tema para garantir ética e segurança nos rumos futuros do seu desenvolvimento.

though high levels of narcissism can impair ethical judgment regardless of one's religious orientation or orthodox beliefs, narcissism is more harmful in those who might be expected to be more ethical, according to a Baylor University study published online in the Journal of Business Ethics. "Devout people who are narcissistic and exercise poor ethical judgment would be committing acts that are, according to their own internalized value system, blatantly hypocritical," said Marjorie J. Cooper, Ph.D., study author and professor of marketing at Baylor's Hankamer School of Business. "Narcissism is sufficiently intrusive and powerful that it entices people into behaving in ways inimical to their most deeply-held beliefs." The study identified three groups- skeptics, nominal Christians, and devout Christians. Skeptics largely reject foundational Christian teachings. Nominal Christians are moderate in their intrinsic religious orientation as well as in their orthodox beliefs. Devout Christians are high in intrinsic religious orientation and orthodoxy, which indicates that they fully internalize Christian beliefs and values. "We found that nominal and devout Christians show better ethical judgment than the skeptics overall, but especially those whose narcissistic tendencies are at the low end of the spectrum," said Chris Pullig, Ph.D., chair of the department of marketing and associate professor of marketing at Baylor. "However, that undergoes a notable alteration as levels of narcissism rise for subjects within each cluster." "Both the nominal and devout groups show degrees of poor ethical judgment equal to that of the skeptics when accompanied by higher degrees of narcissism, a finding that suggests a dramatic transformation for both nominals and the devouts when ethical judgment is clouded by narcissistic tendencies," he said. For the skeptics, the range of scores for ethical judgment from low to high lacks the range that is found for the nominals and devouts. Increased narcissism among skeptics does not result in significantly worse ethical judgment. "However, the same cannot be said for the nominals or the devouts," Cooper said. "For both of these groups as narcissism increases so does the tendency to demonstrate worse ethical judgment. Thus, a higher level of narcissism is more likely to be associated with unethical judgment among nominal Christians and devout Christians than skeptics."

While one widely held view maintains playing video games is intellectually lazy, such play actually may strengthen a range of cognitive skills such as spatial navigation, reasoning, memory and perception, according to several studies reviewed in the article. This is particularly true for shooter video games that are often violent, the authors said. A 2013 meta-analysis found that playing shooter video games improved a player’s capacity to think about objects in three dimensions, just as well as academic courses to enhance these same skills, according to the study. “This has critical implications for education and career development, as previous research has established the power of spatial skills for achievement in science, technology, engineering and mathematics,” Granic said. This enhanced thinking was not found with playing other types of video games, such as puzzles or role-playing games. Playing video games may also help children develop problem-solving skills, the authors said. The more adolescents reported playing strategic video games, such as role-playing games, the more they improved in problem solving and school grades the following year, according to a long-term study published in 2013. Children’s creativity was also enhanced by playing any kind of video game, including violent games, but not when the children used other forms of technology, such as a computer or cell phone, other research revealed.

This is another type of war, new in its intensity, ancient in its origin—war by guerrillas, subversives, insurgents, assassins, war by ambush instead of by combat; by infiltration, instead of aggression, seeking victory by eroding and exhausting the enemy instead of engaging him. It preys on economic unrest and ethnic conflicts. It requires in those situations where we must counter it, and these are the kinds of challenges that will be before us in the next decade if freedom is to be saved, a whole new kind of strategy, a wholly different kind of force, and therefore a new and wholly different kind of military training

There are some not well known risks associated with the program of SETI—the Search for Extra-Terrestrial Intelligence. One of them is the scenario of possible vulnerability from downloading hostile AI with “virus-style” behavior. The proportion of dangerous ET-signals to harmless ones can be dangerously high because of selection effects and evolutionary pressure. Alexey Turchin was born in Moscow, Russia in 1973. Alexey studied Physics and Art History at Moscow State University and actively participated in the Russian Transhumanist Movement. He has translated many foreign Transhumanist works into Russian, including N. Bostrom and E.Yudkowsky. He is an expert in Global Risks and wrote the book “Structure of the Global Catastrophe: Risks of Human Extinction in the XXI Century,” as well as several articles on the topic. Since 2010, he has worked at Science Longer Life where he is writing a book on futurology.

As the 21st Century dawns, warfare is in the midst of revolutionary change. Information Age warfare characterized by knowledge, speed, and precision is slowly supplanting Industrial Age war and its reliance on mass. The advent of precision firepower is but the first tremor of this tectonic shift. As it reverberates around the globe, the Precision Firepower Military Technical Revolution will dramatically increase the lethality and reach of defensive fires. Unless the means for offensive maneuver adapt to overcome the greatly enhanced power of the defense, future soldiers will face stalemate and indecision much like their forefathers confronted in 1914.

There are inherent discrepancies between the nuclear declaratory policy and the nuclear employment policy of most countries, and the United States is no exception. U.S. declaratory policy is what officials say publicly about how nuclear weapons would be used. During the Cold War, official public statements usually suggested that the United States would employ its strategic nuclear arsenal only in retaliation against a Soviet nuclear “first-strike.” But this rationale poses a logical disconnect that suggests an unsettling theory. If the Russians attacked first, there would be little left to hit in retaliating against their nuclear forces, and even less by the time the U.S. “retaliatory” attack arrived at its targets. Many Russian missile silos would be empty, submarines would be at sea, and bombers would be dispersed to airfields or in the air. Ineluctably, the logic of nuclear war planning demands that options exist 14 Natural Resources Defense Councilto fire first. Thus the U.S. President retains a first-strike option, regardless of whether he has any such intention or not. The Soviet Union was faced with a similar dilemma and must have come to similar conclusions. As a consequence, therefore, both sides’ nuclear deterrent strategies have “required” large and highly alert nuclear arsenalsto execute preemptive strike options.

A assimetria se refere ao desbalanceamento extremo de forças. Para o mais forte, a guerra assimétrica é traduzida como forma ilegítima de violência, especialmente quando voltada a danos civis. Para o mais fraco, é uma forma de combate. No pensamento de Clausewitz, a guerra não é arte nem ciência, é um fenômeno que pertence ao campo da existência social, e que, dependendo das condições, pode tomar formas radicalmente diferentes, modificando a sua natureza em cada caso concreto, em analogia ao atributo do camaleão.

"Geoengineering describes activities specifically and deliberately designed to effect a change in the global climate with the aim of minimising or reversing anthropogenic (that is human caused) climate change. Geoengineering covers many techniques and technologies but splits into two broad categories: those that remove carbon dioxide from the atmosphere such as sequestering and locking carbon dioxide in geological formations; and those that reflect solar radiation. Techniques in this category include the injection of sulphate aerosols into the stratosphere to mimic the cooling effect caused by large volcanic eruptions. The technologies and techniques vary so much that any regulatory framework for geoengineering cannot be uniform. Instead, those techniques, particularly carbon removal, that are closely related to familiar existing technologies, could be regulated by developing the international regulation of the existing regimes to encompass geoengineering. For other technologies, especially solar refection, new regulatory arrangements will have to be developed."

Context. WASP-76 b has been a recurrent subject of study since the detection of a signature in high-resolution transit spectroscopy data indicating an asymmetry between the two limbs of the planet. The existence of this asymmetric signature has been confirmed by multiple studies, but its physical origin is still under debate. In addition, it contrasts with the absence of asymmetry reported in the infrared (IR) phase curve. Aims. We provide a more comprehensive dataset of WASP-76 b with the goal of drawing a complete view of the physical processes at work in this atmosphere. In particular, we attempt to reconcile visible high-resolution transit spectroscopy data and IR broadband phase curves. Methods. We gathered 3 phase curves, 20 occultations, and 6 transits for WASP-76 b in the visible with the CHEOPS space telescope. We also report the analysis of three unpublished sectors observed by the TESS space telescope (also in the visible), which represents 34 phase curves. Results. WASP-76 b displays an occultation of 260±11 and 152±10 ppm in TESS and CHEOPS bandpasses respectively. Depending on the composition assumed for the atmosphere and the data reduction used for the IR data, we derived geometric albedo estimates that range from 0.05 ± 0.023 to 0.146 ± 0.013 and from <0.13 to 0.189 ± 0.017 in the CHEOPS and TESS bandpasses, respectively. As expected from the IR phase curves, a low-order model of the phase curves does not yield any detectable asymmetry in the visible either. However, an empirical model allowing for sharper phase curve variations offers a hint of a flux excess before the occultation, with an amplitude of ∼40 ppm, an orbital offset of ∼−30◦ , and a width of ∼20◦ . We also constrained the orbital eccentricity of WASP-76 b to a value lower than 0.0067, with a 99.7% confidence level. This result contradicts earlier proposed scenarios aimed at explaining the asymmetry observed in high-resolution transit spectroscopy. Conclusions. In light of these findings, we hypothesise that WASP-76 b could have night-side clouds that extend predominantly towards its eastern limb. At this limb, the clouds would be associated with spherical droplets or spherically shaped aerosols of an unknown species, which would be responsible for a glory effect in the visible phase curves.

We explore different scenarios to explain the chemical difference found in the remarkable giant-giant binary system HD138202+CD−3012303. For the first time, we suggest how to distinguish these scenarios by taking advantage of the extensive convective envelopes of giant stars. Methods. We carried out a high-precision determination of stellar parameters and abundances by applying a full line-by-line differential analysis on GHOST high-resolution spectra. We used the FUNDPAR program with ATLAS12 model atmospheres and specific opacities calculated for an arbitrary composition through a doubly iterated method. Physical parameters were estimated with the isochrones package and evolutionary tracks were calculated via MIST models. Results. We found a significant chemical difference between the two stars (∆[Fe/H]∼0.08dex), which is largely unexpected considering the insensitivity of giant stars to planetary ingestion and diffusion effects. We tested the possibility of engulfment events by using several different combinations of stellar mass, ingested mass, metallicity of the engulfed object and different convective envelopes. However, the planetary ingestion scenario does not seem to explain the observed differences. For the first time, we distinguished the source of chemical differences using a giant-giant binary system. By ruling out other possible scenarios such as planet formation and evolutionary effects between the two stars, we suggest that primordial inhomogeneities might explain the observed differences. This remarkable result implies that the metallicity differences that were observed in at least some main-sequence binary systems might be related to primordial inhomogeneities rather than engulfment events. We also discuss the important implications of finding primordial inhomogeneities, which affect chemical tagging and other fields such as planet formation. We strongly encourage the use of giantgiant pairs. They are a relevant complement to main-sequence pairs for determining the origin of the observed chemical differences in multiple systems.

A botany file is similar to a chemistry practical file but specifically focuses on experiments and observations related to plants. It typically includes detailed descriptions of plant-related experiments, such as germination studies, growth experiments, tissue culture techniques, plant anatomy investigations, and ecological surveys. The file may contain records of plant specimens collected, their classification, characteristics, and ecological significance. Additionally, it may include diagrams, photographs, drawings, tables, and data analysis related to plant research. Like a chemistry practical file, a botany file serves as a documentation of practical work conducted in the field of botany and is often used for assessment and educational purposes.

Botany is the branch of biology that deals with the scientific study of plants, including their structure, growth, reproduction, metabolism, development, and classification. It encompasses a wide range of topics, from the molecular biology of plant cells to the ecological relationships between plants and their environments. Botany is essential for understanding plant diversity, ecology, evolution, and the roles plants play in ecosystems and human societies.

Context. Determining the size distribution of asteroids is key to understanding the collisional history and evolution of the inner Solar System. Aims. We aim to improve our knowledge of the size distribution of small asteroids in the main belt by determining the parallaxes of newly detected asteroids in the Hubble Space Telescope (HST) archive and subsequently their absolute magnitudes and sizes. Methods. Asteroids appear as curved trails in HST images because of the parallax induced by the fast orbital motion of the spacecraft. Taking into account the trajectory of this latter, the parallax effect can be computed to obtain the distance to the asteroids by fitting simulated trajectories to the observed trails. Using distance, we can obtain the absolute magnitude of an object and an estimation of its size assuming an albedo value, along with some boundaries for its orbital parameters. Results. In this work, we analyse a set of 632 serendipitously imaged asteroids found in the ESA HST archive. Images were captured with the ACS/WFC and WFC3/UVIS instruments. A machine learning algorithm (trained with the results of a citizen science project) was used to detect objects in these images as part of a previous study. Our raw data consist of 1031 asteroid trails from unknown objects, not matching any entries in the Minor Planet Center (MPC) database using their coordinates and imaging time. We also found 670 trails from known objects (objects featuring matching entries in the MPC). After an accuracy assessment and filtering process, our analysed HST asteroid set consists of 454 unknown objects and 178 known objects. We obtain a sample dominated by potential main belt objects featuring absolute magnitudes (H) mostly between 15 and 22 mag. The absolute magnitude cumulative distribution logN(H > H0) ∝ αlog(H0) confirms the previously reported slope change for 15 < H < 18, from α ≈ 0.56 to α ≈ 0.26, maintained in our case down to absolute magnitudes of around H ≈ 20, and therefore expanding the previous result by approximately two magnitudes. Conclusions. HST archival observations can be used as an asteroid survey because the telescope pointings are statistically randomly oriented in the sky and cover long periods of time. They allow us to expand the current best samples of astronomical objects at no extra cost in regard to telescope time.

Chemistry is the scientific study of matter, its properties, composition, structure, and the changes it undergoes. It's often divided into various sub-disciplines such as organic chemistry, inorganic chemistry, physical chemistry, analytical chemistry, and biochemistry. Chemistry plays a crucial role in understanding the world around us and has applications in various fields such as medicine, materials science, environmental science, and industry.

On 26 January 2023, a military pilot reported four potential unidentified anomalous phenomena (UAP) while operating in the Eglin Air Force Base training range off the coast of Florida. Through the onboard radar system, the pilot initially observed that the four objects were aloft between 16,000 – 18,000 feet and appeared to be flying in formation. However the pilot observed only one of the four objects visually and captured two images of the single object via the aircraft’s electro-optical/infrared (EO/IR) sensor (see Figures 1A and 1B). The pilot could not record video of the event because the aircraft’s video recording equipment was inoperable prior to and during the aircraft’s flight. The pilot observed this single object aloft at 16,000 feet. The following case information is based on the pilot’s initial report and a subsequent discussion that AARO held with the pilot to seek additional details about the pilot’s observation of the reported object.
