What if one of the biggest assumptions in cosmology is wrong。 New research suggests the universe may not be perfectly uniform in every direction, as scientists have long believed。 A puzzling mismatch known as the cosmic dipole anomaly shows that the distribution of distant galaxies and quasars doesn’t align with patterns seen in the leftover glow o
In a first experiment, subjects verbalizing the stream of consciousness for a 5-min period were asked to try not to think of a white bear, but to ring a bell in case they did. As indicated both by mentions and by bell rings, they were unable to suppress the thought as instructed. On being asked after this suppression task to think about the white bear for a 5-min period, these subjects showed significantly more tokens of thought about the bear than did subjects who were asked to think about a white bear from the outset. These observations suggest that attempted thought suppression has paradoxical effects as a self-control strategy, perhaps even producing the very obsession or preoccupation that it is directed against. A second experiment replicated these findings and showed that subjects given a specific thought to use as a distracter during suppression were less likely to exhibit later preoccupation with the thought to be suppressed.

The broaden-and-build theory (Fredrickson, 1998, 2001) hypothesises that positive emotions broaden the scope of attention and thought-action repertoires. Two experiments with 104 college students tested these hypotheses. In each, participants viewed a film that elicited (a) amusement, (b) contentment, (c) neutrality, (d) anger, or (e) anxiety. Scope of attention was assessed using a global-local visual processing task (Experiment 1) and thought-action repertoires were assessed using a Twenty Statements Test (Experiment 2). Compared to a neutral state, positive emotions broadened the scope of attention in Experiment 1 and thought-action repertoires in Experiment 2. In Experiment 2, negative emotions, relative to a neutral state, narrowed thought-action repertoires. Implications for promoting emotional well-being and physical health are discussed.
When Richard Nisbett showed an animated underwater scene to his American students, they zeroed in on a big fish swimming among smaller fish.Japanese subjects, on the other hand, made observations about the background environment...and the different seeings are a clue to profound underlying cognitive differences between Westerners and East Asians. As Professor Nisbett shows in The Geography of Thought people actually think - and even see - the world differently, because of differing ecologies, social structures, philosophies, and educational systems that date back to ancient Greece and China, and that have survived into the modern world. As a result, East Asian thought is holistic - drawn to the perceptual field as a whole, and to relations among objects and events within that field. By comparison to Western modes of reasoning, East Asian thought relies far less on categories, or on formal logic: it is fundamentally dialectic, seeking a middle way between opposing thoughts. By contrast, Westerners focus on salient objects or people, use attributes to assign them to categories, and apply rules of formal logic to understand their behavior.
We conducted several tests of the idea that an inclination toward thought suppression is associated with obsessive thinking and emotional reactivity. Initially, we developed a self-report measure of thought suppression through successive factor-analytic procedures and found that it exhibited acceptable internal consistency and temporal stability. This measure, the White Bear Suppression Inventory (WBSI), was found to correlate with measures of obsessional thinking and depressive and anxious affect, to predict signs of clinical obsession among individuals prone toward obsessional thinking, to predict depression among individuals motivated to dislike negative thoughts, and to predict failure of electrodermal responses to habituate among people having emotional thoughts. The WBSI was inversely correlated with repression as assessed by the Repression-Sensitization Scale, and so taps a trait that is quite unlike repression as traditionally conceived.
In spite of the double burden of racial and gender discrimination, African-American women have developed a rich intellectual tradition that is not widely known. In Black Feminist Thought, Patricia Hill Collins explores the words and ideas of Black feminist intellectuals as well as those African-American women outside academe. She provides an interpretive framework for the work of such prominent Black feminist thinkers as Angela Davis, bell hooks, Alice Walker, and Audre Lorde. The result is a superbly crafted book that provides the first synthetic overview of Black feminist thought.

The Moment is a classic study of the consequences for modern historical and social consciousness of the ideal of the classical republic revived by Machiavelli and other thinkers of Renaissance Italy. J.G.A. Pocock suggests that Machiavelli's prime emphasis was on the moment in which the republic confronts the problem of its own instability in time, and which he calls the Machiavellian moment.After examining this problem in the thought of Machiavelli, Guicciardini, and Giannotti, Pocock turns to the revival of republican thought in Puritan England and in Revolutionary and Federalist America. He argues that the American Revolution can be considered the last great act of civic humanism of the Renaissance. He relates the origins of modern historicism to the clash between civic, Christian, and commercial values in the thought of the eighteenth century.
A two-volume study of political thought from the late thirteenth to the end of the sixteenth century, the decisive period of transition from medieval to modern political theory. The work is intended to be both an introduction to the period for students, and a presentation and justification of a particular approach to the interpretation of historical texts. Quentin Skinner gives an outline account of all the principal texts of the period, discussing in turn the chief political writings of Dante, Marsiglio, Bartolus, Machiavelli, Erasmus and more, Luther and Calvin, Bodin and the Calvinist revolutionaries. But he also examines a very large number of lesser writers in order to explain the general social and intellectual context in which these leading theorists worked. He thus presents the history not as a procession of 'classic texts' but are more readily intelligible. He traces by this means the gradual emergence of the vocabulary of modern political thought, and in particular the crucial concept of the State. We are given an insight into the actual processes of the formation of ideologies and into some of the linkages between political theory and practice. Professor Skinner has been awarded the Balzan Prize Life Time Achievement Award for Political Thought, History and Theory.

In its original edition, Bruce Trigger's book was the first ever to examine the history of archaeological thought from medieval times to the present in world-wide perspective. Now, in this new edition, he both updates the original work and introduces new archaeological perspectives and concerns. At once stimulating and even-handed, it places the development of archaeological thought and theory throughout within a broad social and intellectual framework. The successive but interacting trends apparent in archaeological thought are defined and the author seeks to determine the extent to which these trends were a reflection of the personal and collective interests of archaeologists as these relate - in the West at least - to the fluctuating fortunes of the middle classes. While subjective influences have been powerful, Professor Trigger argues that the gradual accumulation of archaeological data has exercised a growing constraint on interpretation. In turn, this has increased the objectivity of archaeological research and enhanced its value for understanding the entire span of human history and the human condition in general.
In these innovative essays, Vivian Sobchack considers the key role our bodies play in making sense of today's image-saturated culture. Emphasizing our corporeal rather than our intellectual engagements with film and other media, Carnal Thoughts shows how our experience always emerges through our senses and how our bodies are not just visible objects but also sense-making, visual subjects. Sobchack draws on both phenomenological philosophy and a broad range of popular sources to explore bodily experience in contemporary, moving-image culture. She examines how, through the conflation of cinema and surgery, we've all "had our eyes done"; why we are "moved" by the movies; and the different ways in which we inhabit photographic, cinematic, and electronic space. Carnal Thoughts provides a lively and engaging challenge to the mind/body split by demonstrating that the process of "making sense" requires an irreducible collaboration between our thoughts and our senses.
"Gesture and Thought expands on McNeill's acclaimed classic Hand and Mind. While that earlier work demonstrated what gestures reveal about thought, here gestures are shown to be active participants in both speaking and thinking. Expanding on an approach introduced by Lev Vygotsky in the 1930s, McNeill posits that gestures are key ingredients in an "imagery-language dialectic" that fuels both speech and thought. Gestures are both the "imagery" and components of "language." The smallest element of this dialectic is the "growth point," an "idea unit" of an utterance at its beginning psychological stage. Utilizing several innovative experiments he created and administered with subjects spanning several different age, gender, language, and neurological groups. McNeill's shows how growth points organize themselves into utterances and extend to discourse at the moment of speaking."--BOOK JACKET.
The global cobalt supply chain is more interconnected—and more vulnerable—than previously thought, with disruptions capable of triggering far-reaching cascades across multiple countries and industries。 Researchers warn that protecting battery supply chains will require system-wide coordination because critical bottlenecks can turn local shocks into
For decades, scientists thought royal jelly was the secret ingredient that turned an ordinary honeybee larva into a queen。 New research reveals the process is far more remarkable: young worker bees create special “royal cribs” made from customized wax, carefully regulate warmth and humidity, and dedicate entire teams of attendants to raising future
A surprising discovery is overturning a long-held assumption about how the brain’s movement center works。 Researchers found that two key cerebellar cell types—thought to be tightly linked—often don’t behave in predictable ways, even though one directly influences the other。 The finding suggests scientists may have been relying on the wrong signals
Physicists have developed a new optical centrifuge that can precisely spin molecules inside a superfluid for the first time。 The advance could help unravel some of the biggest mysteries of quantum liquids and reveal how superfluidity breaks down at the atomic scale
Researchers have created quantum control techniques that can make a system appear to run backward in time。 By precisely managing quantum measurements, they can reshape the system's arrow of time and even harvest energy from the measurement process itself。 The breakthrough could lead to more powerful quantum computers, quantum batteries, and other a
