Continual learning in artificial intelligence, particularly in multimodal models that integrate both visual and textual information, has become a pivotal area of research. A recent paper titled “A Practitioner’s Guide to Continual Multimodal Pretraining” by Karsten Roth et al. introduces a framework known as FoMo-in-Flux, aimed at improving how these models are continually updated to stay relevant and accurate over time.
Multimodal foundation models are employed in various applications that merge vision and language. However, as new tasks and data become available, these models can become outdated. The paper identifies two primary strategies for continuous pretraining:
Infrequent, large-scale updates involving a significant amount of new data.
Frequent, smaller updates that focus on specific information through localized adjustments.
The authors note that practical deployment often lies in the challenging middle ground between these approaches, necessitating a more nuanced strategy for adapting models throughout their life cycles. In real-world applications, models frequently need to adapt to evolving subdomains and tasks without undergoing full retraining[1].
The authors developed FoMo-in-Flux as a benchmark for evaluating continual multimodal pretraining under realistic computational constraints. This framework is built on 63 diverse datasets, making it versatile for examining how models can be adaptively updated over time. Importantly, FoMo-in-Flux allows researchers to explore:
Data-centric strategies, assessing how different data mixtures and streaming orders influence performance.
Method-centric strategies, which analyze fine-tuning techniques ranging from simple updates to complex continual learning strategies.
Meta-learning rate schedules that optimize learning rates dynamically, influencing the effectiveness of continual updates[1].
The research highlights the trade-off between knowledge retention (the model's ability to maintain pre-existing knowledge) and adaptation (the capacity to acquire new information). The authors found that:
Naive continual fine-tuning often yields the highest knowledge accumulation but can lead to significant losses in zero-shot performance (the model’s effectiveness on unseen tasks).
Parameter-efficient finetuning methods (like LoRA) prioritize knowledge retention at the expense of new knowledge accumulation. Interestingly, model merging techniques show promise in simultaneously achieving good retention and adaptation, suggesting that carefully combining models may be a fruitful strategy across extended update cycles[1].
Learning rates were found to drastically affect the outcomes of continual pretraining. The implementation of meta-learning rate schedules, where the learning rate is adjusted across tasks based on prior performance, can significantly bridge the gap between knowledge accumulation and retention. The study demonstrated that using a well-crafted learning schedule, specifically tailored to account for the duration of update cycles, can lead to improved results without the need for additional hyperparameters[1].
The findings indicate that the manner in which data updates are sequenced in continual learning scenarios can significantly impact model performance. The paper discusses the concept of “i.i.d”-fying (independently and identically distributed) the learning process, which involves creating update cycles that are consistent and representative of the underlying data distribution.
The choice of data mixture ratios, including the proportions of new data versus previously seen data, proved to be crucial. For example:
Replay of prior adaptation data was much more beneficial than relying solely on fresh data.
The authors recommend balancing these aspects to optimize performance without overwhelming the model with unrelated updates[1].
The paper's insights into continual multimodal pretraining provide a structured approach for researchers and practitioners looking to deploy models that adapt over time. By examining various factors—such as data management, method selection, and learning rates—the authors contribute to a growing understanding of how to maintain the effectiveness of multimodal models amidst evolving datasets and tasks.
FoMo-in-Flux not only sets a new benchmark for future research but also opens the door for further investigations into how models can better handle continual learning. Potential future research avenues include exploring more complex meta-learning rate schedules, assessing the scalability of model sizes and compute budgets, and refining training mixtures for optimal performance regarding knowledge retention and adaptation[1].
As the intersection of AI continues to expand, the tools and frameworks like FoMo-in-Flux will undoubtedly play a vital role in shaping the future of continual learning in multimodal contexts.

Binchotan charcoal, often referred to as Japanese white charcoal, is celebrated for its exceptional grilling properties and versatility in enhancing the flavor of various dishes. Originating from the Wakayama prefecture in Japan, particularly associated with the Kishu region, binchotan is crafted from ubame oak, which is known for its dense structure and high carbon content. Unlike standard charcoal, binchotan is characterized by its long-lasting burn, minimal smoke, and odorless qualities, making it a favorite among chefs and culinary experts worldwide.
The production of binchotan involves a meticulous and labor-intensive process. First, the ubame oak wood is carefully gathered from challenging terrains and then placed in a traditional earthen kiln. The wood is heated for approximately seven to ten days at controlled temperatures. Initially, the kiln's temperature is maintained around 240°C (464°F) to remove moisture, followed by a significant increase to over 1,000°C (1,832°F) for carbonization. This process strips the wood of impurities and results in a charcoal product that is over 95% pure carbon[1][2][10].
Once carbonized, the charcoal is smothered with a mixture of ash, earth, and sand to extinguish any remaining fire, a step crucial to its unique whitish-gray appearance. This production technique is not only labor-intensive but also requires significant craftsmanship, contributing to the higher price point of binchotan compared to conventional charcoal options[5][4].
One of the defining characteristics of binchotan is its high carbon purity, often reaching up to 96% in some types like Kishu binchotan[7]. This makes it a cleaner-burning option that produces minimal smoke and no unpleasant odors, allowing the natural flavors of grilled foods to shine through. Chefs claim that binchotan allows for a more authentic taste, especially when cooking traditional Japanese dishes such as yakitori (grilled chicken skewers) and unagi (grilled eel)[7][9].
Binchotan is renowned for its impressive burn duration of three to five hours, during which it can maintain high temperatures ranging from 500°C to about 1,800°F[7][11]. This ability to generate sustained, even heat makes it ideal for high-precision cooking, enhancing the Maillard reaction and improving searing on meats and seafood. Furthermore, its capacious nature allows it to be extinguished and reused several times without significant loss of performance, making it economical for repeated use in grilling sessions[5][9].
In addition to its culinary uses, binchotan charcoal possesses numerous practical applications. It is known for its effectiveness as an odor absorber, commonly utilized in homes and refrigerators to keep spaces fresh[8]. Moreover, its porous structure allows it to purify water by binding to chemicals, making drinking water cleaner[5][8]. There are even culinary experiments that involve using powdered binchotan in food preparations to enhance flavors or improve health benefits, showcasing its versatility[8][10][12].
The rising demand for binchotan charcoal has raised concerns regarding the sustainability of ubame oak forests. Overharvesting threatens the longevity of these resources, prompting some producers to adopt more sustainable practices to ensure the continued availability of this premium grilling material[7]. It is essential for consumers to seek out reputable suppliers who engage in responsible harvesting methods.
Binchotan charcoal stands out as an artisanal, high-quality charcoal appreciated for its unparalleled grilling performance and flavor-enhancing capabilities. Whether used for traditional Japanese cooking or modern culinary experiments, it brings unique benefits not found in typical charcoal products. As consumers increasingly value quality and sustainability, binchotan remains a top choice for enthusiasts, chefs, and home cooks who seek exceptional results in their grilling endeavors[6][13].

Comedians have long played a vital role in society by addressing controversial and taboo topics through humor. Their ability to challenge societal norms and spark conversations about sensitive issues reflects the profound impact of comedy on cultural discourse. This report delves into the various strategies comedians use to navigate taboo subjects while balancing humor and sensitivity.
Taboo comedy, often defined by its willingness to address topics considered off-limits or uncomfortable, thrives on pushing boundaries. This genre utilizes humor to confront the unspoken and invites audiences to grapple with their own biases and preconceptions. Rather than shying away from sensitive themes, comedians engage with them directly, employing satire and irony as tools to provoke thought while eliciting laughter. By using humor as a release for pent-up psychological tension, comedians can address taboo subjects in ways that provide catharsis for both themselves and their audiences[2][5].
The roots of taboo comedy can be traced back to the ribald humor of burlesque shows and vaudeville acts, where explicit language and sexual innuendo were common. Comedians like Lenny Bruce and George Carlin pushed the genre forward, fearlessly addressing societal taboos and challenging censorship laws with their routines[1]. Bruce's controversial performances and Carlin's infamous 'Seven Words You Can Never Say on Television' sparked debates around freedom of expression, showcasing how humor could be used as a vehicle for societal critique[1][4].
As societal norms have evolved, so too has the approach comedians take when addressing sensitive topics. Contemporary comedians leverage their platforms to tackle complex issues related to race, gender, sexuality, and politics, often blending humor with social commentary to highlight societal injustices[5][7]. For instance, Dave Chappelle has been known for his audacious exploration of race and social issues, prompting reflections on uncomfortable truths in a palatable form[5][8].
Comedians employ various techniques when tackling taboo subjects to ensure that their humor resonates without crossing ethical boundaries.
One of the primary tools used in taboo comedy is satire, which critiques societal norms through exaggerated or ironic portrayals. This approach allows comedians to address contentious topics, such as politics and religion, while engaging audiences critically[6][9]. Comedians like Ricky Gervais and Amy Schumer utilize satire to challenge conventional attitudes, prompting discussions surrounding issues like gender roles and societal expectations[9]. Such humor invites audiences to reassess their preconceived notions while maintaining an entertaining experience.
Many comedians opt to weave personal experiences into their routines when discussing sensitive topics. For example, Daniel Sloss's comedic show 'Dark' explores the deeply personal tragedy of losing a sibling while intertwining humor with his journey of grief. By sharing personal hardships, he fosters a sense of connection with the audience, allowing people who have faced similar struggles to find relief through laughter[2]. Similarly, performers like Sarah Millican openly discuss relational and body image issues, using relatable humor to empower audiences facing similar challenges[2][4].
Successful taboo comedy often hinges on the comedian's ability to balance humor with a sensitivity to the subject matter. Many comedians navigate this challenge by ensuring that their punchlines promote inclusivity rather than exclusion. For instance, comedians are sometimes advised to 'punch up' rather than 'punch down,' targeting those in power rather than marginalized groups[8]. This approach helps mitigate potential backlash and ensures that the jokes foster meaningful dialogue rather than perpetuating harmful stereotypes.
Today’s comedians must also consider audience reactions carefully. The rise of social media has amplified the potential for backlash against controversial material, making it essential for comedians to gauge audience sensibilities[5][8]. Audiences play a significant role in shaping comedic narratives; comedians often adjust their acts based on the collective feedback from their viewers, adapting to evolving social attitudes and cultural dialogues[4][8]. This responsiveness underscores that while comedians wield the power of humor, the ultimate acceptance of their material rests with their audience.
The impact of taboo comedy extends beyond mere entertainment; it fosters critical conversations around sensitive issues. Comedy serves as a mirror reflecting societal challenges and encouraging discourse on uncomfortable subjects. By addressing topics such as mental health, discrimination, and societal inequalities through humor, comedians can make these issues more accessible to wider audiences, prompting introspection and understanding[7][9]. Ultimately, the role of comedy in society can be seen as a powerful catalyst for change, expanding the boundaries of acceptable discourse and encouraging audiences to engage with challenging topics in new ways[1][7].
Comedians tackle taboo subjects by embracing humor as a powerful means of engaging with sensitive themes. Through satire, personal narratives, and an awareness of audience reactions, they navigate the complexities of modern societal norms while provoking thought and discussion. As the landscape of comedy continues to evolve, so does its potential to challenge societal conventions and contribute to meaningful dialogues on pressing issues. By navigating the fine line between humor and sensitivity, comedians not only entertain but also enlighten, teaching us to confront our biases while promoting empathy and understanding within society.

The question of whether there are living rocks on Earth stems from two related but distinct observations. On one hand, rocks themselves are inert, non-living entities composed of minerals. On the other hand, they can act as natural shelters for living organisms, especially resilient microorganisms that inhabit tiny crevices. This report explores both aspects by integrating recent discoveries of microbes living within ancient rocks and the fundamental nature of rocks as non-living materials.
Rocks are, by definition, non-living. As explained in one source, a rock is a solid mass of geological materials that does not move, grow, or reproduce. The text points out that even though rocks can host living matter, they themselves do not have cells or metabolic processes. Specifically, the explanation clarifies that even though a rock can contain bacteria or other forms of life, the rock is not alive because it lacks the freedom to move, process energy, or reproduce on its own[4]. This perspective draws a clear distinction between the inert nature of the rock and the dynamic life forms that might be found within or on its surface.
Recent scientific studies have demonstrated that microorganisms have been discovered living deep within ancient rocks. In an extraordinary discovery, researchers identified microbial cells residing in minuscule fractures of a 2-billion-year-old volcanic rock from South Africa[1]. The study involved staining the microbial DNA and imaging the cells using advanced microscopy techniques. The researchers confirmed that these cells were indigenous to the rock sample, as they compared them with potential contaminants. One key observation was the intact cell walls of these microbes—a clear indication of life, even after billions of years. A similar study described in another source highlighted that these microbes had been living in isolation for far longer than any previously known subterranean microbial community, a fact that broke records previously held by 100-million-year-old seafloor sediments[2].
The concept of life within rocks is frequently linked to the study of endoliths—organisms that live inside rock substrates or within mineral grain boundaries. Endoliths are found in various environments ranging from surface rocks to deep terrestrial and ocean crusts[3]. These organisms often include members of the Bacteria, Archaea, and Fungi kingdoms and can exist under extreme conditions, such as in total darkness and with limited access to nutrients. The presence of these endolithic communities has not only expanded our understanding of the resilience and adaptability of life on Earth, but it also underscores the potential for similar life forms to exist on other planets, where surface conditions may be harsh but subsurface environments could offer viable habitats.
The discoveries of living microbes inside ancient rocks have significant implications for both geology and the search for extraterrestrial life. While rocks themselves are clearly non-living, as detailed in the explanation from Yes Dirt[4], the fact that living organisms can thrive within them offers a unique perspective on the preservation of life over geological timescales. For example, the discoveries in the Bushveld Igneous Complex not only provide clues about the early evolution of life on Earth but also suggest that similar rock formations on Mars might harbor living microorganisms[1][2]. This connection between deep Earth biology and astrobiology has led researchers to consider the deep subsurface as an important area for ongoing exploration and study.
In summary, while rocks are inherently non-living entities that do not possess growth, metabolism, or reproduction, they can nonetheless serve as hosts to life. The existence of resilient microbial communities within ancient rock formations demonstrates the remarkable capacity of life to colonize and persist in even the most inhospitable environments. This duality—that rocks are non-living yet capable of nurturing living organisms—is central to our understanding of both geological processes and biological evolution. The findings serve as a poignant reminder that life finds a way, even in the seemingly inert corners of our planet[1][2][3][4].

Art has played a transformative role in civil rights movements, serving as a crucial medium for expression, protest, and change. Throughout history, artists have utilized various forms of creative expression to address social injustices, inspire hope, and galvanize communities into action. This report examines how art has influenced civil rights movements through its ability to critique power structures, communicate collective experiences, and foster solidarity.
Artists have long used their work to critique political systems and address social injustices. Through various mediums—including paintings, music, literature, and performance—artists bring attention to oppression, corruption, and the struggles of marginalized communities. For example, the iconic works of Francisco Goya and George Orwell highlight how art can serve as a powerful vehicle for political dissent. Goya’s painting “The Third of May 1808” and Orwell’s novel “1984” exemplify the capacity of art to provoke emotions and stimulate public discourse about topics like war and totalitarianism, respectively[1].
During the Civil Rights Movement in the United States, the power of music was particularly evident. Artists like Bob Dylan, Nina Simone, and Sam Cooke used their songs to convey messages of equality and resistance, playing a pivotal role in mobilizing support for civil rights efforts[1]. This intertwining of music and activism exemplifies how artistic expressions resonate deeply with people's emotions, fostering collective identities and shared purposes among communities.
Art has historically provided a platform for marginalized communities to share their experiences and aspirations. For instance, during the Civil Rights era, Black artists used their work to challenge dominant narratives and amplify the voices of African Americans. Jacob Lawrence and Elizabeth Catlett created powerful visuals that depicted the struggles of Black Americans, thereby bringing attention to their fight for equality[4][11]. Such artworks encapsulated the essence of the movement, fostering empathy and raising awareness about the issues faced by African Americans.
Additionally, artists like Frida Kahlo and Banksy illustrate how personal and socially charged themes can connect with broader movements. Kahlo’s exploration of identity and pain in her self-portraits resonates with struggles for social justice and acceptance, while Banksy’s street art confronts issues like war and inequality, engaging audiences in critical conversations about contemporary societal dilemmas[1][3]. These artists utilize their platforms to challenge stereotypes and advocate for marginalized voices, reflecting the enduring relevance of art in civil rights discourse.
Beyond individual expression, art serves as a catalyst for community engagement and collective action. Public art, murals, and installations often become focal points for protests, transforming spaces into sites of activism. For example, the transformation of the Robert E. Lee statue’s base in Richmond, Virginia, into a vibrant display of protest art exemplifies how communities reclaim spaces to voice their grievances and commemorate victims of injustice[2]. Such engagements illustrate how art can inspire communities to come together and mobilize for social change.
Artistic initiatives not only galvanize action but also cultivate solidarity among diverse groups. Street art and public installations frequently bridge cultural divides, fostering dialogue and understanding among individuals from varying backgrounds. This aspect of art encourages inclusivity, as it invites participation from the public and asserts that everyone has a stake in the fight against oppression[1][4][11].
Art also functions as a means of memory and commemoration, preserving the narratives of civil rights struggles for future generations. Memorials and sculptures dedicated to pivotal moments in these movements serve as reminders of the past, shaping collective consciousness and inspiring ongoing activism. The use of art in memorializing events, such as the struggles against apartheid or the civil rights movement, fosters reflection and learning, ensuring that the lessons of history are not forgotten[1][5].
For instance, works by artists like Faith Ringgold, whose “American People Series #20: Die” captures the anxiety and rage during the tumultuous periods of civil rights protests, underline the emotional weight of such artworks. These pieces commemorate the struggles while encouraging viewers to reflect on the ongoing fight for justice[12]. By creating a space for remembrance, art continues to inspire new generations in the pursuit of equality.
In sum, art profoundly influences civil rights movements by critiquing power, amplifying marginalized voices, fostering community solidarity, and preserving collective memories. Through its capacity to evoke emotions and provoke discourse, art serves as a critical tool for social change, allowing individuals and communities to articulate their struggles and aspirations for a more just and equitable society. As demonstrated through various artistic expressions, the interplay between art and activism continues to resonate in the ongoing fight for civil rights today.

Creating a consistent nighttime routine is essential for improving sleep quality and overall well-being. A well-structured routine signals your body that it’s time to wind down, making it easier to fall asleep and stay asleep. Here’s how to establish an effective night routine based on proven strategies and expert recommendations.
A reliable sleep schedule is crucial for regulating your body’s internal clock. Aim to go to bed and wake up at the same time every day, including weekends. This consistency helps reinforce your sleep-wake cycles, making it easier to fall asleep and wake up refreshed[1][2][9]. Establishing a set timeframe for your sleep allows your body to anticipate rest, which contributes to better sleep quality.
Begin preparing for sleep at least 30 to 60 minutes before your designated bedtime. Allocate this time for winding down and engaging in relaxing activities, which alerts your mind and body to transition from the hustle of the day to rest[3][6]. Activities like reading, listening to calming music, or practicing gentle yoga can promote relaxation and signal that it’s time for sleep[2][9][10].
Your sleep environment plays a vital role in the quality of your rest. It should be conducive to sleep, meaning it should be cool, dark, and quiet. Aim to set your bedroom temperature between 65 and 68 degrees Fahrenheit, which is considered optimal for most people[1][4]. Use blackout curtains, earplugs, or white noise machines to minimize disturbances from outside light and sound[3][8]. Additionally, removing electronic devices or placing them out of reach can help maintain a distraction-free environment, preventing sleep disruptions caused by notifications or screen time before bed[1][11].
Reducing stimulating activities in the evening can significantly improve your ability to fall asleep. This includes avoiding caffeine and heavy meals within several hours of bedtime, as these can lead to discomfort and make it harder to rest[9][10]. Instead, focus on light snacks or calming herbal teas, such as chamomile, which can aid relaxation. Additionally, heavy exercise close to bedtime can also interfere with sleep; therefore, it's advisable to conclude any vigorous workouts at least an hour or two before sleep[6][12].
Incorporating soothing rituals into your bedtime routine can help you relax before sleep. Consider practices such as:
Meditation or Deep Breathing: These techniques can calm the mind and body, reducing anxiety and promoting relaxation[2][7]. Simple meditation practices can help clear your head of stressful thoughts, making it easier to drift off.
Warm Baths or Showers: Taking a warm shower or bath an hour before bed can help lower your body temperature post-bath, signaling to your body that it’s time to sleep[1][11].
Mindful Journaling: Spend a few minutes reflecting on your day or jotting down thoughts and worries. This practice can free your mind from racing thoughts and prepare you for rest[6][10].
One of the most effective ways to improve sleep hygiene is to limit screen time before bed. The blue light emitted by phones, tablets, and computers suppresses the production of melatonin, the hormone responsible for sleep[7][11]. Aim to turn off all electronic devices at least an hour before bed to allow your body to produce melatonin effectively. Instead, engage in non-stimulating activities like reading a physical book or listening to soft music.
Your sleeping area should be entirely dedicated to rest. Avoid using your bed for activities other than sleep and intimacy, as this can create associations that hinder your ability to fall asleep easily[8][11]. Keep your bedding comfortable and ensure your mattress is appropriate for your needs—this contributes greatly to a good night’s sleep.
Be mindful of what you consume in the hours leading up to bedtime. Avoid large meals, caffeine, alcohol, and nicotine, as these can interfere with your ability to fall asleep or stay asleep[3][9]. Instead, if you’re hungry, a light snack can be helpful.
Establishing a nighttime routine that incorporates these practices can lead to improved sleep quality, which in turn enhances daily functioning and overall health. By setting a consistent sleep schedule, creating a relaxing bedtime environment, disconnecting from stimulating activities, and practicing calming rituals, you cultivate the conditions necessary for a restorative night’s sleep. Make it a priority to implement these steps, and you may find the perfect path to peaceful slumber.
