Ghost sharks grow forehead teeth to help them have sex

Male “ghost sharks” — eerie deep-sea fish known as chimaeras that are related to sharks and rays — have a strange rod jutting from their foreheads, studded with sharp, retractable teeth. New research reveals these are not merely lookalikes, but real rows of teeth that grow outside the mouth. What’s more, the toothy appendage is likely used for mating. Found only in males, the forehead rod — called a tenaculum — is the ghost sharks’ only source of distinct teeth, and it seems to be used to grasp females in much the same way sharks use their toothy mouths in mating. “If these strange chimaeras are sticking teeth on the front of their head, it makes you think about the dynamism of tooth development more generally,” said Gareth Fraser, Ph.D., a professor of biology at the University of Florida and senior author of the study. “If chimaeras can make a set of teeth outside the mouth, where else might we find teeth?” The team, including scientists from the University of Washington and the University of Chicago, studied both fossils and living specimens to solve the mystery. A 315-million-year-old fossil showed the tenaculum attached to the upper jaw, bearing teeth incredibly similar to those in the mouth. Modern chimaeras collected from Puget Sound revealed the same tooth-growing process on the head, seen in modern-day shark jaws. And genetic testing confirmed they expressed the same tooth-specific genes as oral teeth. “What we found is that the teeth on this strange appendage look very much like rows of shark teeth. The ability to make teeth transferred onto that appendage, likely from the mouth,” Fraser said. “Over time, the tenaculum shortened but retained the ability to make oral teeth on this forehead appendage.” Fraser collaborated with Washington’s Karly Cohen, Ph.D., and Michael Coates, Ph.D., from Chicago on the study, which was published this week in the Proceedings of the National Academy of Sciences. As experts in shark evolution and anatomy, the scientists were intrigued by these tooth-filled rods sprouting from the ghost shark foreheads. The central mystery: Is the tenaculum covered in true teeth related to oral teeth or more similar to the tooth-like scales plastering the skin of sharks and some ghost sharks? CT scans of the fossils and modern chimaeras gave the scientists unprecedented, detailed insights into the development of the tenaculum teeth, which looked remarkably similar to the teeth of today’s sharks. The nail in the coffin came from genetic evidence. The tenaculum teeth express genes found only in true teeth, never in shark skin denticles. "What I think is very neat about this project is that it provides a beautiful example of evolutionary tinkering or ‘bricolage,’” said Coates, a professor of biology at the University of Chicago. “We have a combination of experimental data with paleontological evidence to show how these fishes co-opted a preexisting program for manufacturing teeth to make a new device that is essential for reproduction." Cohen, a postdoctoral researcher at the University of Washington’s Friday Harbor Labs and first author of the paper, said scientists had never spotted teeth outside the mouth in this way before. “The tenaculum is a developmental relic, not a bizarre one-off, and the first clear example of a toothed structure outside the jaw,” she said. The bizarre path from a mouth full of teeth to forehead teeth used for mating demonstrates the impressive flexibility of evolution, the researchers say, always ready to repurpose structures for strange and unexpected new uses. “There are still plenty of surprises down in the ocean depths that we have yet to uncover,” Fraser said.

How a UF reading program is reaching classrooms worldwide

For more than 25 years, Holly Lane, Ph.D., has been laser-focused on a global educational goal: to ensure that students worldwide have access to information about reading. Her passion project, known as the University of Florida Literacy Institute, or UFLI, has already improved the literacy skills of more than 10 million children. What began as a modest classroom tool now has a Facebook community of over 273,000 members; 18 million online toolbox views; and more than 500,000 instructional manuals in classrooms. And as the UFLI brand gains traction, Lane continues to champion what the acronym means and why the program has been so life-changing. “When you learn to read, you fly,” said Lane, who serves as the UFLI director and a professor of special education at UF. UFLI is an ongoing effort by UF faculty and students to improve literacy outcomes for struggling students by addressing two key areas: reader development and teacher development. The program began in 1998 as a tutoring model for beginning readers working with Lane’s pre-service teachers. The idea was that, if teachers understood how to employ effective, evidence-based practices in a one-on-one tutoring session, they could transfer those skills to their small-group or classroom instruction. However, some teachers struggled to make that transition, so a dedicated small-group lesson model was created. That foundation eventually expanded into a dyslexia support program and caught the attention of a surprising partner, best-selling author and philanthropist James Patterson. Known worldwide for his literacy advocacy and generous support of reading initiatives, Patterson has become a key benefactor for the program. When the COVID-19 pandemic hit, a challenge turned into a breakthrough. UFLI started its Virtual Teaching Resource Hub and, in the first week, about 70,000 teachers visited the site and downloaded materials. The turning point came when a school in St. Augustine reached out to UFLI, asking for professional development. “I said, ‘Well, what if we planned the lessons for you instead of teaching you how to plan these lessons?’” Lane said. What followed was what Lane called her “accidental phonics program.” “They ended the year with the best scores they'd ever seen, better than their pre-COVID scores, and that was unheard of,” Lane said. That success led to an effective district-wide pilot in Alachua County with 21 elementary schools. UFLI leaders decided to publish the contents of the program and create a manual that individual teachers could purchase. This concept boomed, and the program even made waves overseas. “Starting with the virtual teaching hub… we had a huge following in Perth and in Melbourne, and now we have an Australian edition of the manual,” Lane said. “We’ve been in every state and every Canadian province and territory, but we're also now in something like 60-some other countries.” Patterson has continued his support by directing efforts toward expanding UFLI’s reach in Florida, aiming to bring the program to every district in the state. Looking ahead, Lane is especially excited about UFLI’s new technology. “We're calling it our assessment and planning portal,” Lane said. “Teachers assess two skills a week, and they enter their data into this program and it spits out small-group lesson plans for the following week that target specific needs of their students.” The data input system is highly advanced, requiring the teacher to simply hold up work in front of a webcam, and the system then reads the student handwriting and imports the data. The program’s structure also ensures that students apply new concepts daily and revisit them regularly. But behind it all is a deeply connected community. For Lane, the success of UFLI boils down to people. “We have an amazing team here,” Lane said. “If anything, that's my superpower, finding really good people who are really good humans but also really good at what they do.” For more information about UFLI, visit ufli.education.ufl.edu.

Expert Q&A: What is Soft Diplomacy and how does it impact classrooms?

"Right now, storytelling is critical. Language learning is highly personal, and it’s the person-to-person relationships that grease the wheels," says Cheryl Ernst, director of the English Language Institute at the University of Delaware. She recently published English Language Programs as Facilitators of Soft Diplomacy in Innovations in Star Scholars Press. Here's how she's discussing this important topic.  Q: What is the focus of this research, and why is it important? Ernst: ELI and other English language programs provide the ideal space for communication development, cross cultural appreciation, gaining life skills, and raising awareness about people beyond the media. Post pandemic, we’re hearing across campus how individuals feel less connected, and in English language classrooms, connection is critical. Language is only learned through production and practice since it’s a skill that needs to be honed. In language, there is no such thing as perfect. In our classrooms, English is the common goal, and everyone comes to that space at their own levels and overflowing with imperfection. Our students learn to use their vulnerability as a tool. They learn the value of a growth mindset living in a culture that is different from their own, and with that comes an appreciation for difference, respect for others, trust, human-to-human communication. Q: What inspired this research? Ernst: More than 30 years of observation, conversations, experiences, and personal relationships. There was no term to describe the skills English language programs teach beyond grammar (what’s perceived, anyway). Terms like personal diplomacy, person-to-person diplomacy, civic diplomacy, and the like happens all the time and oversimplifies what we do. In my readings, I started to see overlaps between soft power and diplomacy, which led to the concept of Soft Diplomacy. Then what distinguishes Soft Diplomacy from other more common monikers are the variety of skills that happen organically in our classrooms that we rarely acknowledge and students may not recognize. Q: What are some key findings or developments? Ernst: Institutionally, ELPs can do better highlighting the skills beyond English that we teach organically or deliberately. Q: How could this work potentially impact the field or the wider public? Ernst: Respecting ELPs for the space they provide and the skills they offer. It’s not “just English,” rather is learning to communicate in a common language and with people from around the globe. I’d like people to realize that relationships are foundational, that there are common values across nations and that differences are not bad. What version of English is “correct” British or American dialects (the New York? Wisconsin? Alabama? Iowa?). Q: What are the next steps or upcoming milestones in your research? Ernst: A former student and I have launched a podcast series called Soft Diplomacy in Action that focuses on personal stories from those who work in international education. We’ve interviewed an ELI associate professor from Morocco, the UD coordinator of the Mandela Fellows program, a professor who sees (and lives) the diplomatic value of sports, and a retired English language professional. We’re looking forward to continuing these conversations with individuals from a variety of disciplines that also work in this space but through different lenses. ABOUT CHERYL ERNST Cheryl Ernst is the director of the English Language Institute at the University of Delaware where she and her colleagues and students practice Soft Diplomacy every day. Her professional areas of interest include program administration and international marketing, teacher training and working with international teaching assistants, curriculum design, and advanced level academic English (graduate levels).

Reading for pleasure in free fall: New study finds 40% drop over two decades

A sweeping new study from the University of Florida and University College London has found that daily reading for pleasure in the United States has declined by more than 40% over the last 20 years — raising urgent questions about the cultural, educational and health consequences of a nation reading less. Published today in the journal iScience, the study analyzed data from over 236,000 Americans who participated in the American Time Use Survey between 2003 and 2023. The findings suggest a fundamental cultural shift: fewer people are carving out time in their day to read for enjoyment. “This is not just a small dip — it’s a sustained, steady decline of about 3% per year,” said Jill Sonke, Ph.D., director of research initiatives at the UF Center for Arts in Medicine and co-director of the EpiArts Lab, a National Endowment for the Arts research lab at UF in partnership with University College London. “It’s significant, and it’s deeply concerning.” Who’s reading and who isn’t The decline wasn’t evenly spread across the population. Researchers found steeper drops among Black Americans than white Americans, people with lower income or educational attainment, and those in rural (versus metropolitan) areas — highlighting deepening disparities in reading access and habits. “While people with higher education levels and women are still more likely to read, even among these groups, we’re seeing shifts,” said Jessica Bone, Ph.D., senior research fellow in statistics and epidemiology at University College London. “And among those who do read, the time spent reading has increased slightly, which may suggest a polarization, where some people are reading more while many have stopped reading altogether.” The researchers also noted some more promising findings, including that reading with children did not change over the last 20 years. However, reading with children was a lot less common than reading for pleasure, which is concerning given that this activity is tied to early literacy development, academic success and family bonding, Bone said. Why it matters Reading for pleasure has long been recognized not just as a tool for education, but as a means of supporting mental health, empathy, creativity and lifelong learning. The EpiArts Lab, which uses large data sets to examine links between the arts and health, has previously identified clear associations between creative engagement and well-being. “Reading has historically been a low-barrier, high-impact way to engage creatively and improve quality of life,” Sonke said. “When we lose one of the simplest tools in our public health toolkit, it’s a serious loss.” The American Time Use Survey offers a unique window into these trends. “We’re working with incredibly detailed data about how people spend their days,” Bone said. “And because it’s a representative sample of U.S. residents in private households, we can look not just at the national trend, but at how it plays out across different communities.” Why are Americans reading less? While causes were not part of the study, the researchers point to multiple potential factors, including the rise of digital media, growing economic pressures, shrinking leisure time and uneven access to books and libraries. “Our digital culture is certainly part of the story,” Sonke said. “But there are also structural issues — limited access to reading materials, economic insecurity and a national decline in leisure time. If you’re working multiple jobs or dealing with transportation barriers in a rural area, a trip to the library may just not be feasible.” What can be done? The study’s authors say that interventions could help slow or reverse the trend, but they need to be strategic. “Reading with children is one of the most promising avenues,” said Daisy Fancourt, Ph.D., a professor of psychology and epidemiology at University College London and co-director of the EpiArts Lab. “It supports not only language and literacy, but empathy, social bonding, emotional development and school readiness.” Bone added that creating more community-centered reading opportunities could also help: “Ideally, we’d make local libraries more accessible and attractive, encourage book groups, and make reading a more social and supported activity — not just something done in isolation.” The study underscores the importance of valuing and protecting access to the arts — not only as a matter of culture, but as a matter of public health. “Reading has always been one of the more accessible ways to support well-being,” Fancourt said. “To see this kind of decline is concerning because the research is clear: reading is a vital health-enhancing behavior for every group within society, with benefits across the life-course.”

VCU College of Engineering receives $600,000 for AI-driven cybersecurity research

To advance AI-enabled cybersecurity research, the National Science Foundation (NSF) presented Kemal Akkaya, Ph.D., professor and chair of the Department of Computer Science, with a $600,000 grant through the organization’s Cybersecurity Innovation for Cyberinfrastructure program. Akkaya’s three-year project will explore how large language models (LLMs) can automate packet labeling for intrusion detection systems. “From transportation and healthcare to finance, improving the accuracy of machine learning algorithms used to defend the networks that underpin these sectors’ cyberinfrastructure is critical for protecting them from cyberattacks. Strengthening these defenses helps ensure the reliability and security of the essential services people rely on every day,” said Akkaya. Intrusion detection systems monitor network traffic to identify suspicious or malicious activity. These systems rely on machine learning models trained on large volumes of accurately labeled data. Producing those datasets, however, is time intensive and often requires expert cybersecurity knowledge. As digital systems increasingly power transportation, health care, finance and communication, the volume and sophistication of cyber attacks continue to grow. At the same time, artificial intelligence is reshaping how both attackers and defenders operate. Improving how quickly and accurately security systems can be trained is critical to protecting the infrastructure that supports daily life. Akkaya’s project will investigate how generative AI can help address this challenge. The team will fine tune open-source large language models using network data, threat signatures and expert annotations. Model accuracy will be strengthened through retrieval-augmented refinement, ensemble modeling and human-in-the-loop verification. Labeled datasets will be released in stages to support the development and evaluation of cybersecurity models. Using data from AmLight, an international research and education network operated by Florida International University (FIU), the project includes collaboration with researchers from FIU. The award strengthens VCU’s growing leadership in AI-enabled cybersecurity research and provides hands-on research training for graduate students. Resulting datasets from this work will support machine learning education for undergraduate students.

Director Gennady Miloshevsky, Ph.D., shares his vision for the nuclear program at the VCU College of Engineering

Recently named the nuclear program director at the Virginia Commonwealth University (VCU) College of Engineering, Gennady Miloshevsky, Ph.D., associate professor in the Department of Mechanical & Nuclear Engineering, answers some questions about the direction of VCU Engineering’s nuclear program and what he hopes it can accomplish. What are your top priorities for the nuclear program at the VCU College of Engineering? I want to focus on student development, innovative research and our rankings in best program lists, but that is not everything. Strategy is important. We need to align ourselves with the country’s national energy needs. There are many new developments in the energy sector, like small modular reactors or fusion energy systems, and having the right faculty to engage with these advancements is important. Providing students with a well-rounded education and good opportunities for gaining experience benefits the College of Engineering’s public and private sector partners. Nuclear subject matter is complex, so higher education is very important for workforce development. We want to build partnerships, like the one we have with Dominion Energy, that support this goal. A priority for me is continuing to establish relationships with Commonwealth Fusion Systems, which seeks to build and operate the first commercial grid-scale fusion plant in Chesterfield County, Virginia. Our workforce partners will benefit from VCU’s well-trained nuclear engineering graduates joining the workforce. So, aligning our strategy with national energy needs, hiring the right faculty to support our programs and building industry partnerships that benefit our student’s education and career opportunities are important things for VCU Engineering’s nuclear program. Where would you like to see the College of Engineering’s nuclear program 10 years from now? I would like to see growth in the nuclear program. For example, some new graduate courses on topics like nuclear materials or fusion energy. In 2024, I developed a general course for fusion energy, so building out a curriculum that goes more in-depth would be good. When you look at small modular reactors and micro reactors, current energy policy does not allow private companies to build their own. However, as energy demands increase, policy could change to where you see these compact devices installed in places like data centers, for example. A more in-depth curriculum allows VCU Engineering students to step into industry roles that lead growth of the energy industry while also ensuring students are capable of adapting to the changing field and taking advantage of new developments. What sort of cross-disciplinary opportunities are there for the College of Engineering’s nuclear program? Nuclear engineering and nuclear science are very interdisciplinary fields. You have physics that covers the nuclear reaction and the radiation it generates, for example, then chemistry is needed when talking about nuclear fuel cycles and nuclear waste. You also need materials science because good materials capable of withstanding radiation and high temperatures are needed in nuclear fission and fusion energy systems. This science then connects to engineering, building the reactors, the energy distribution systems like a power grid. It is a small sample of the overall work, but you see how mechanical and electrical engineering are key to this part. All these disciplines come together to solve the same problem. One researcher might be figuring out how to confine plasma and make it stable, then another researcher is looking at how plasma can disrupt the containment wall and how to make materials to protect the wall. Within our department, we are making connections between mechanical-focused faculty working on high-temperature ceramics or additive manufacturing techniques and those of us researching nuclear energy systems in order to make joint proposals. We are also collaborating outside VCU. As an example, I am involved with an alliance founded by the Defense Threat Reduction Agency (DTRA) comprised of 17 universities, research labs and military centers. Coordinated through DTRA, we work together on many of the same problems.Through this partnership, my Ph.D. students do summer research rotations with national labs like Lawrence Livermore National Laboratory in California and The Pacific Northwest National Laboratory. We also bring cadets and midshipman into VCU from other institutions, like the DTRA Nuclear Science and Engineering Research Center, United States Military Academy West Point and the Virginia Military Institute, whose students have been part of research experience for undergraduates programs in the summer. How is artificial intelligence impacting the field of nuclear engineering? So, the United States is sponsoring the Genesis Mission, which seeks to transform science innovation through the power of AI. One area of the Genesis Mission is nuclear fission and fusion energy. I see this playing out with the Department of Energy encouraging national labs, universities and industry to work together on applying these AI advancements to solve the research problems of nuclear energy. It is a great opportunity for students, who we can involve in this work to give them real-world experience with topics they will see after graduation. Last semester I taught a course at VCU on the practical applications of AI on nuclear engineering problems. It is not something like ChatGPT or anything like that. What we did is take Google’s TensorFlow platform that is a library of AI models and machine neural networks. Using Python scripting students learn how to apply these AI resources to about 30 problems in mechanical and nuclear engineering. They create scripts, use data sets and run analytics. We have a nuclear reactor simulator and I have some ideas to create AI-based software we can pair with the simulator, then give the software a data set and let it control the operation of the simulator in a safe way. Tell us about your background. What brought you VCU and the Department of Mechanical and Nuclear Engineering? Actually, I am not a mechanical or a nuclear engineer. My background is in physics. I graduated from the Belarusian State University in 1990 and continued to a Ph.D. in physics from the Heat and Mass Transfer Institute of the National Academy of Sciences of Belarus working on topics related to fusion plasmas and nuclear weapon effects. In space, nuclear weapons produce shockwaves and radiation. I computationally model these effects in my research to determine how something like a nuclear warhead detonation in orbit will impact the materials a satellite is made of, for example. My research also crosses over into nuclear fusion, specifically thermodynamic and optical plasma properties, fusion plasma disruptions, melt motion and splashing from plasma facing components. Accelerating Next-Generation Extreme Ultraviolet (EUV) Lithography (ANGEL) is my most recent collaborative project, supported by the Department of Energy’s (DOE) Office of Science, Fusion Energy Sciences. It involves two national laboratories, three universities and a private-sector company focusing on advancement of future micro-electronic chips, EUV photon sources, mitigation of material degradation and plasma chemistry. Prior to joining the VCU College of Engineering I worked at Purdue University at a DOE-funded center investigating nuclear fusion and the effects of plasma on materials. Around 2019 I wanted to develop my own lab, so I came to VCU with startup funds from the Nuclear Regulatory Commission and DTRA. My first priority after joining the VCU College of Engineering was continuing my fusion research, the second was collaborating with an alliance of universities focused on work for DTRA and DOE.

Expert Q and A: Understanding "Punch," The Baby Monkey That Captured The World's Heart

A tiny Japanese macaque named Punch has unexpectedly become one of the internet’s most talked-about animals. Born at a zoo in Japan and rejected by his mother shortly after birth, the young monkey was hand-raised by staff and given a stuffed toy for comfort—an image that quickly ricocheted across social media worldwide. Videos showing Punch tentatively approaching other macaques, sometimes being pushed away or corrected as he tried to socialize, struck an emotional chord. What began as a local zoo update rapidly turned into international headlines, with audiences from North America to Europe weighing in on what they saw as loneliness, resilience and the universal need for belonging. But experts say the story is more nuanced than a viral clip suggests. The interactions that many viewers interpreted as bullying are, in fact, typical components of macaque social development, part of how young primates learn boundaries, hierarchy and group norms. While Punch’s early maternal separation makes his integration more delicate, gradual acceptance into the troop is a positive sign. As internet users continue to share and comment, the moment has sparked broader conversations about animal emotion, anthropomorphism and the realities of wildlife behavior in managed care settings. Florida Tech's Catherine Talbot offered insight into the complexities of animal behavior.  Catherine F. Talbot is an assistant professor in the School of Psychology at Florida Tech and co-director of the Animal Cognitive Research Center at Brevard Zoo. Her overarching research goal has been to study the ultimate (evolutionary) and proximate (behavioral, biological, and developmental) mechanisms underlying sociality. Q: Is it normal for mother macaques to abandon their babies, or is this an unusual occurrence? What circumstances can cause this to happen?  It’s not necessarily normal, but also not that uncommon in primates, unfortunately. It’s more common in first time mothers that are inexperienced and sometimes lower ranking mothers. A number of factors can increase the likelihood of abandonment including stress on the mother and unfavorable conditions such as limited resources. Q: How does abandonment affect development in young macaques?  Early maternal contact is critical for normal behavioral and emotional development. Infants rely on their mothers for nutrition, warmth, protection and learning how to navigate social dynamics. When infants do not have their mothers during critical developmental periods like infancy, in the short term, they tend to have elevated stress responses and difficulty with emotional regulation. In the long-term, it depends on whether the infant is able to form other types of attachment. In the worst-case scenario, they may have increased aggression, abnormal and/or self-injurious behavior, digestive issues and may lack social skills. But primates are resilient, and with social support and gradual integration into a troop, Punch can form new attachments, learn socially appropriate behavior and ultimately live a fairly normal monkey life. Q: Is it obvious to the rest of the troop when a young macaque has no mother? How does this affect integration?  Japanese macaques have really complex social worlds, so they are really in tune with the relationships they have with one another and recognize the relationships between other individuals. That can certainly make it more difficult for Punch to be accepted back into the troop – he needs to find some friends and possibly even a surrogate parent. With social support, he should be able to recover from the absence of a mother. It’s really great to see that the care staff stepped in to support Punch as he begins to recovery from the stress of this experience. It’s even more important that Punch is around other monkeys of the same species so that he can continue to learn from them and respond appropriately to social communication cues. I’m thrilled to see that Punch is now making friends. Q: Punch is obviously attached to his stuffed orangutan. We can understand how this happens from our own human experience, but can you explain, on a biological level, how he bonded with this stuffed animal? Primates, including humans, are neurobiologically wired to form strong social bonds with a caregiver very early in life. In many primate species, infants are born highly dependent on their mother. Punch’s attachment to the stuffed orangutan reflects this need for attachment. That physical touch – warmth, softness, graspable limbs, a stable physical presence – can partially activate those same calming biological pathways, including the release of oxytocin which regulates stress and promotes feelings of safety. Without activation in those pathways, Punch would likely experience stronger feelings of separation or loneliness and ultimately social withdrawal. These biological pathways are crucial to proper social and emotional development of any primate species. Any way we can help mitigate those effects for Punch is crucial for successful integration back into his troop. Q: How does sociality among Japanese macaques compare to that of similar species? Japanese macaques live in large multi-male, multi-female social groups that can range from roughly 50 to 150 individuals. Like many macaques species, they form stable, female-bonded societies. Females remain in their natal group (or the group they were born into) for life, inherit their mother’s rank, and form strong kin- based alliances whereas males emigrate to a new group at adolescence. Their societies are organized around matrilines or extended female family lines in which rank is very important. They have strong dominance hierarchies and generally high levels of aggression, but levels of aggression and tolerance can vary a good amount from group to group. Entire matrilines can outrank others, which dictates access to food, grooming partners, and coalitions. Within a single troop, you often see multiple matrilines with long-standing dominance competitions. I sometimes compare it to a Romeo and Juliet-style Montague and Capulet dynamic, where beneath the surface of daily grooming and foraging is a complex political landscape structured by kinship and status. Q: What behaviors can Punch expect from the rest of the monkeys as he continues to integrate with the troop? What behaviors can the troop expect to see from him? As Punch continues to integrate into his troop, I would expect to see some social testing by other members of the group to see how Punch responds- they may use mild aggression like open mouth threats or direct stares (which arethreatening is macaques), brief chases, and displacement from resources like food/resting spots. These will help clarify Punch’s rank and help form and maintain a stable hierarchy. Therefore, I hope to see Punch make at least a few strong social bonds (friends), to help defend him against more intense aggression. As long as he makes a few friends, he should begin to receive more affiliative behavior. Integration is usually gradual as these bonds form and strengthen and these skills develop. I would expect to see more play and grooming with conspecifics and less reliance on his stuffed orangutan as real social bonds start to form. Grooming is especially important for forming and maintaining social bonds and there are already videos showing Punch receiving some grooming from older monkeys, which bodes well for him. He also needs to respond in socially appropriate ways, like grooming others and showing submission to higher ranking individuals. Essentially, he needs to understand and follow the rules of Japanese macaque society. Q: What message do you have as people continue to root for Punch?  It's uplifting to see how much support Punch has gained across the world. And while Punch is clearly adorable and so vulnerable that you just want to love him and give him (or other monkeys like him) a home, it’s important to remember that more than anything else, he needs to live with other monkeys so that he can live a life that is true to his species and nature. Unfortunately, many people still have monkeys as pets. The illegal wildlife trade is a multi-billion-dollar industry, ranking as the fourth largest illegal trade after drugs, arms, and human trafficking. Within the United States, it is estimated that there are more than 15,000 nonhuman primates living in unsuitable conditions. Primates are intelligent, sentient beings that need complex communities and relationships to thrive. There currently is no federal legislation that protects primates from private ownership, but the Captive Primate Safety Act (H.R.3199/ S.1594) has been proposed to prohibit the private possession of nonhuman primates and the sale or transportation of nonhuman primates for the wild pet trade.
