Neurons on a chip have demonstrated the capability to learn and play the classic arcade game Pong. This learning occurs through a real-time closed-loop system where electrical stimulation indicates the x and y positions of the ball relative to the paddle. The neural cultures exhibit self-organization and adapt their activity based on feedback, which improves their performance over time, suggesting a move towards goal-directed behavior indicative of intelligence[2][1].
In as little as minutes, these neuronal networks can track the ball and control the paddle, exhibiting a level of adaptability that outperforms traditional deep reinforcement learning algorithms in sample efficiency[2][1]. This advancement highlights the potential of biocomputers in learning and responding dynamically to stimuli in simulated environments.

Art has always been a reflection of the human experience, intertwined with the cultural and societal shifts that shape its context. Through the ages, artistic expressions have been deeply influenced by cultural movements, which have continually redefined the parameters of what art can convey and achieve. Below, we will explore how various artistic periods and movements have been influenced by changing social, political, and cultural landscapes.
From the Paleolithic cave paintings to contemporary installations, art has served as a chronicle of human history. These early artworks documented cultural practices and societal narratives, establishing a basis for artistic expression that has evolved over millennia. The significance of context cannot be overstated; it provides the lens through which art can be understood and appreciated. Early art was primarily a tool for acknowledging and recording experiences, laying the foundation for complex societal dialogues that would emerge in later periods[3].
The Renaissance marked a significant cultural shift in Europe, characterized by a renewed interest in classical philosophy and humanism. This era embraced the exploration of human potential, leading to masterpieces that celebrated human form and emotion. Artists like Leonardo da Vinci and Michelangelo leveraged perspective and realism to reflect their society's evolving values and aspirations[8]. This period not only emphasized the technical prowess of artists but also marked a shift in the subject matter, favoring depictions of individuals and an exploration of themes related to humanity over divine representations[6][11].
Emerging as a reaction against the strict ideals of Neoclassicism, Romanticism placed a premium on emotional depth and individual experience. Artists like Francisco Goya illustrated the tumultuous human condition through intense emotional imagery, thus capturing the essence of societal upheaval and personal struggle[10]. This focus on emotion paves the way for subsequent movements, as artists began to question established norms and explore the sublime aspects of nature and human experience[5].
The advent of Modernism further severed ties with traditional artistic conventions. Characterized by bold experimentation and the rejection of historical styles, Modernism embraced abstraction, fragmentation, and new forms of expression. Movements such as Cubism, established by Pablo Picasso and Georges Braque, deconstructed subjects into geometric forms, representing a departure from conventional perspectives and an embrace of contemporary life's complexities[8][10]. This radical shift reflected a broader cultural shift towards individualism and subjective experience.
Throughout history, art has taken on the role of a vehicle for social commentary, often influenced by the pressing political and social issues of the time. From the Dada movement, which arose in response to World War I's chaos, to the Harlem Renaissance, which celebrated African American culture and identity, artists have used their work to reflect societal tensions and aspirations[4][9][11]. The Dada artists, for example, employed absurdity and nihilism in their works to critique the establishment and traditional values, thus rendering art a significant discourse on social critique[2].
In the 20th century, movements like Surrealism explored the unconscious mind and its relationship to reality, further pushing the boundaries of artistic expression. Artists such as Salvador Dalí utilized dream-like imagery to challenge societal norms and explore deeper psychological themes[8]. The interplay between art and psychology not only reflects individual experiences but also broader societal transformations.
Contemporary art has continued this trajectory by increasingly becoming intertwined with activism and social justice movements. Artists today often refocus their work to address issues such as race, gender, and environmental sustainability, using their platforms to amplify marginalized voices and provoke critical public discourse[5]. For instance, artist Tania Bruguera engages communities in creating art that is not only participatory but also emphasizes social responsibility and activism[11]. This shift highlights a significant transformation in the role of the artist from a solitary creator to a facilitator of collective dialogue and action.
The use of visual language in protest materials, which includes vibrant colors and compelling imagery, has evolved into a vital aspect of modern activism. Art has become a rallying point for communities, enabling them to express grievances and demand justice. This collective approach to art increasingly positions it as a potent form of social change, capable of transcending barriers and fostering dialogue[9][10].
The relationship between cultural movements and artistic expressions is an intricate tapestry that reflects humanity's evolving values, struggles, and aspirations. As history shows, art does not exist in a vacuum; it is continually shaped by its socio-political context. Each movement, from the Renaissance to contemporary activism, showcases how art serves not only as a reflection of society but also as a powerful tool for initiating change. By understanding the interplay between culture and art, we can appreciate the rich narrative that has unfolded through human creativity and expression. As we move forward, the role of art as a catalyst for dialogue, transformation, and resilience remains vital in navigating the complexities of modern society[1][2].

Autonomous Sensory Meridian Response (ASMR) refers to a tingling sensation that typically begins on the scalp and spreads to the neck and spine, producing feelings of relaxation and euphoria. Described as akin to a mild electrical current, ASMR is usually triggered by auditory stimuli like whispering, tapping, and crinkling sounds, along with visual stimuli associated with personal attention or intricate activities. The sensation has gained popularity as both a phenomenon and a form of online content, particularly through platforms like YouTube.
The modern history of ASMR began in 2007, when a user named 'okaywhatever' initiated a discussion on the health forum SteadyHealth titled 'Weird Sensation Feels Good.' This thread described a tingling sensation experienced since childhood, which resonated with many others, revealing a shared phenomenon amongst participants who reported similar feelings in response to various stimuli like whispering and gentle movements[4][9].
The term 'ASMR' itself was coined in 2010 by Jennifer Allen, a participant in these discussions who sought to formalize the term to lend it legitimacy. Allen defined ASMR to signify the autonomously triggered sensory reaction distinct from sexual arousal, emphasizing its role in relaxation and comfort[5][6][9][11]. She explained that 'autonomous' reflects the individual nature of the trigger, while 'meridian' denotes a peak experience without connotations of climax associated with orgasm[6][10][11].
As awareness of ASMR grew, online platforms like YouTube became central hubs for both content creators (known as ASMRtists) and audiences seeking these soothing experiences. In 2009, the first ASMR-specific YouTube channel, WhisperingLife, emerged, initiating a wave of whisper videos that would lay the groundwork for the burgeoning ASMR community. By 2010, a Facebook group dedicated to ASMR, called ASMR Research & Support, was created, facilitating further discussion and community-building among those experiencing ASMR[1][3][7].
These early ASMR videos gradually attracted considerable attention, often featuring soft-spoken narration, tapping sounds, and simulated personal attention[1][6]. The community began to flourish, with ASMRtists like Maria GentleWhispering gaining large followings, eventually leading to the proliferation of diverse styles and formats[10][11].
As ASMR's popularity grew, researchers started examining its effects. The first significant peer-reviewed research published in 2015 surveyed individuals experiencing ASMR, revealing that many use it to alleviate insomnia and stress, with a high percentage reporting improved emotional well-being after watching ASMR content[8][9]. More recent studies employed fMRI technology to investigate brain activity during ASMR experiences, finding that areas associated with reward and social bonding were activated more strongly in those who experience ASMR compared to those who do not. This suggests a potential link between ASMR and social interactions, akin to the calming effects of touch and personal attention[8][10].
While many ASMR practitioners view the phenomenon as a benign and therapeutic experience, it has not been immune to misconceptions, often being mischaracterized as sexual or fetishistic[4][5][10][11]. This misunderstanding has led to defensive attitudes within the community, as many users felt stigmatized or ridiculed for their experiences[6][9]. Despite this, media representation has evolved, with ASMR receiving mainstream attention through advertising and appearances in popular films, such as the 2017 movie Battle of the Sexes, which sought to replicate the soothing effects of ASMR in cinematic form[10][11].
ASMR continues to evolve as a genre, now encompassing a vast array of content including relaxation videos, guided meditations, and even role-play scenarios. With millions of videos uploaded and a growing audience, ASMR has cemented its place in contemporary digital culture[10]. As scientific research progresses, there is potential for ASMR to be recognized for its therapeutic applications, especially in treating anxiety and insomnia.
In conclusion, the history of ASMR reflects a fascinating intersection of digital media, community building, and psychological research. From a niche online discussion to a burgeoning global phenomenon, ASMR illustrates how shared experiences in the digital age can lead to deeper investigations into human sensations and emotional well-being.

Hurricanes are named by the World Meteorological Organization (WMO) using a strict procedure established by the organization[5]. The names are chosen from lists of male and female names for Atlantic hurricanes, and they rotate on a six-year cycle[5]. The Hurricane Committee at the WMO selects common names familiar to the regions affected by the storms to aid in communication and tracking of the threats[6]. In the event of a particularly deadly or costly storm, its name may be retired to prevent confusion[5]. If there are more than twenty-one named storms in a season, additional names from a supplemental list are used[5]. The practice of naming hurricanes started in the early days of meteorology in the United States and has become common language, increasing public awareness of hurricanes[4].

The tourism industry is undergoing significant transformations as countries adapt to the realities of post-COVID tourism. Recovery strategies are focusing on enhancing resilience, sustainability, and the overall visitor experience.
International tourism is on track to recover fully, with arrivals reaching about 97% of pre-pandemic levels in early 2024. This recovery has been supported by a strong resurgence in travel demand, improved air connectivity, and strategic adaptations by various countries[3][9]. For instance, in January to March 2024, more than 285 million international tourists traveled, representing about a 20% increase compared to the same period in 2023, highlighting a rapid rebound of the sector[9].
Various regions have showcased remarkable performance during this recovery phase. The Middle East, for example, has seen international arrivals exceed pre-pandemic levels by 36% in early 2024, while Europe reached 120 million international tourists during the first quarter, buoyed by strong intra-regional travel demand[9]. Asia and the Pacific, though lagging slightly behind, reached 82% of pre-pandemic levels, with concerted efforts in reopening key markets and implementing effective travel facilitation measures[9].
In rebuilding tourism, countries have shifted their focus toward domestic travel, recognizing its potential as a primary driver of economic recovery. As highlighted in the McKinsey report, the bulk of travel spending is expected to stay local, with domestic travelers accounting for approximately 75% of total expenditures[8]. Various governments are actively promoting domestic travel by leveraging local attractions and creating special packages aimed at engaging residents. For instance, Viet Nam has emphasized domestic tourism with discounted offers to build local demand as they begin to recover[2].
Local tourism authorities are also encouraging residents to explore their surroundings, a strategy that not only revitalizes local economies but also helps manage the risks associated with international tourism and overcrowding[7]. The focus on domestic travelers allows destinations to cater to emerging traveler preferences while ensuring that local cultures and economies benefit from tourism expenditures.
Adapting to the post-COVID tourism landscape includes a strong emphasis on sustainability. Countries are increasingly aware of their ecological footprint and are implementing policies aimed at promoting sustainable practices within the industry. For instance, there is an urgent call for improved waste management infrastructure to handle the increase in single-use plastics and biomedical waste brought about by the pandemic[2].
Moreover, there is a growing recognition of the need to incorporate sustainability measures into tourism planning. Governments are considering legislation for biodiversity protection and introducing taxes for tourists to fund conservation efforts[2]. This approach helps to safeguard natural resources and create a more sustainable tourism model that can withstand future disruptions.
Despite the positive trends, the tourism sector still faces significant challenges. These include ongoing economic pressures such as inflation, high interest rates, and geopolitical tensions that may hamper further recovery. The World Economic Forum has identified these factors as critical impediments to stable growth in international tourism, calling for continued adaptation and strategic management by governments[4][9].
The impact of rising costs is already influencing consumer behavior, with travelers increasingly seeking value for their money and preferring closer, more familiar destinations[8]. This trend has prompted tourism sectors to evolve their offerings, ensuring they align with current economic realities while still appealing to travelers' desires for new and enriching experiences.
In response to shifting consumer expectations post-pandemic, the tourism sector is enhancing the overall visitor experience through digitalization and improved communication. Many destinations are adopting technology to streamline the booking process, facilitate contactless experiences, and provide personalized service to visitors[8]. For example, advanced AI applications are enabling companies to better understand consumer behavior and tailor offerings accordingly, fostering a more engaging travel experience[8].
Moreover, marketing strategies are increasingly focusing on uplifting local narratives and culturally relevant experiences, which resonate with travelers who value sustainability and community engagement. Efforts to promote lesser-known destinations are also being ramped up to distribute visitor traffic more evenly and avoid overtourism in popular locales[6][8].
The path to fully reestablishing international tourism in a post-COVID world is complex and multifaceted. By prioritizing domestic travel, enhancing sustainable practices, and integrating digital solutions, countries aim to create a more resilient tourism landscape that benefits both economies and local communities. The recovery of international tourism is not merely about returning to pre-pandemic levels; it's about rethinking the tourism experience and ensuring that it aligns with contemporary expectations and challenges.

In the early years of cinema, women played significant roles both in front of and behind the camera. Female filmmakers, such as Alice Guy-Blaché, were pioneers in creating diverse narratives. However, as the film industry evolved, particularly during Hollywood's Golden Age (1910–1960), women's roles began to diminish significantly. Research indicates that female representation hit an all-time low during this period, where women constituted only about 40% of the film workforce in acting roles, and even less in directing and production positions[1]. The consolidation of power within a few male-dominated studios drastically reduced the opportunities for women, as male producers often preferred to hire male directors and writers[1][2].
The introduction of the studio system from 1915 to 1920 marked a significant shift in the film industry. Women experienced a steady increase in participation before this system emerged, yet by 1930, the number of acting roles for women halved, and producing and directing roles nearly vanished[1]. The portrayal of women in this era often reverted to traditional stereotypes, with female characters frequently depicted as damsels in distress, requiring male protagonists to rescue them[4]. Such archetypes reinforced the notion of women as passive and inferior, a template that continued into the following decades.
The 1970s saw a gradual shift with the rise of feminist movements, leading to increased awareness regarding gender inequality in cinema. Films like Alien (1979) introduced strong female characters such as Ellen Ripley, who broke from traditional female roles to become a pioneering action hero[4]. Despite this progress, the industry still maintained a patriarchal structure that limited women's roles, both on screen and in production capacities. Reports suggested that by the mid-1980s, although women had begun to penetrate areas traditionally seen as 'male-only' spheres, they remained severely underrepresented behind the camera[2][4].
In recent decades, women in the film industry have made inroads, though significant challenges remain. For instance, a 2017 report highlighted that women made up only 17% of the behind-the-scenes workforce in the film industry—from directors to producers—indicating an ongoing struggle for recognition and equality[2]. Additionally, among the top 250 films from the 2015-2016 period, 96% had no female cinematographers and 92% had no female directors[2]. Such figures reflect the deeply ingrained biases against women, perpetuating gender inequalities that still resonate today.
The impact of movements like #MeToo and Time's Up has sparked critical conversations around gender disparities, yet the outcome in terms of representation has been mixed. Even amidst these movements, the portrayal of women at awards nominations remains starkly imbalanced, with few female filmmakers receiving recognition for their work[2]. It is this duality of presence and absence that continues to define women's roles in contemporary cinema.
Recent studies have indicated an overall increase in female representation in cinema, yet the statistics reveal a nuanced reality. For instance, films directed by women tend to feature a higher percentage of female characters and crew members, yet these films often receive reduced budgets compared to their male-directed counterparts[7]. Moreover, the Bechdel test, a common standard for evaluating female representation, shows that although the number of films passing the test has increased, the meaningful depiction of women still often falls short[5].
According to recent trends, while female cast ratios have improved over time, they are often correlated with lower budgets and box office returns, indicating that systemic issues persist within the industry[5]. Research emphasizes the need for greater investment in films with strong female narratives, asserting that women's perspectives in filmmaking are critical for enhancing diversity and inclusivity in storytelling[7].
The portrayal of women in cinema has evolved significantly over the decades, transitioning from strong early presences to diminishing roles during the Golden Age, and gradually returning to more nuanced representations in contemporary films. Despite the strides made, the film industry continues to grapple with gender inequalities that restrict women’s roles both in front of and behind the camera. It is crucial for upcoming narratives to focus on fostering environments that support women filmmakers and challenge entrenched stereotypes, thereby creating a more balanced and inclusive cinematic landscape. The continued advocacy for women's rights in the industry underscores the importance of striving for parity and genuine representation in storytelling.
