Managing mental well being is critical in times of uncertainty and unpredictability. One common coping mechanism is to connect in-person with friends or family because isolation can negatively impact those experiencing depression and anxiety.
Amid concerns over COVID-19, however, that recommendation conflicts with health and safety instructions on social distancing. Dr. Tonya Hansel and Dr. Maurya Glaude, licensed clinicians and researchers at the Tulane University School of Work, have the following suggestions to prevent increased at-home time from negatively affecting a person’s mental health.
Set up a routine and workspace dedicated to work. Use sticky notes, calendars, journals or other office supplies to help you stay organized and remember what you need to accomplish.
Email, message or call your colleagues or classmates. This will not only allow you to connect for mental well-being but also allow you to gain clarity and understanding about a particular assignment.
Recharge with fresh air, exercise and entertainment. This could include taking a midday walk or bike ride around your neighborhood, going on a nature hike or enjoying a snack on your porch. Allow more sunlight into your work space.
Maintain running, walking or cycling routines but bring your own water, avoid drinking out of public fountains and keep approximately 6 feet from others as recommended by the U.S. Centers for Disease Control.
Use the time you save from commuting to do extra things around your house, such as spring cleaning, cooking or gardening. Or create a piece of art or do craft projects with your children.
Feel free to allow small indulgences. Giving yourself or your children a little extra screen time is a way of practicing self-care.
Use technology — Facetime, Google Hangouts, Zoom or the phone — to keep up with friends and family and support one another.
Nearly 9 in 10 parents say teens spend too much time gaming but many mistaken about child’s video game behavior
Eighty-six percent of parents agree that teens spend too much time gaming, but many may be mistaken about the extent of their own child’s video game habits, a new national poll suggests.
Parents also report very different gaming patterns for teen boys than girls, according to the C.S. Mott Children’s Hospital National Poll on Children’s Health. Twice as many parents say their teen boy plays video games every day compared to parents of teen girls. Teen boys are also more likely to spend three or more hours gaming.
Overall, parents surveyed say gaming often gets in the way of other aspects of their teen’s life, such as family activities and interactions (46%), sleep (44%), homework (34%), friendship with non-gaming peers (33%) and extracurricular activities (31%).
“Although many parents believe video games can be good for teens, they also report a number of negative impacts of prolonged gaming,” says Mott Poll co-director and Mott pediatrician Gary Freed, MD, MPH.
“Parents should take a close look at their teen’s gaming behavior and set reasonable limits to reduce harmful impacts on sleep, family and peer relationships and school performance.”
But parents may not always have the most accurate perception of their teen’s gaming tendencies. Among parents of daily gamers, 54% report their teen plays three or more hours a day (compared to only 13% of teens that do not play every day.) Just 13 percent of these parents believe their teen spends more time gaming than others, while 78% believe their teen’s gaming is less than or about the same as their peers.
“Many parents of frequent gamers have a misconception that the amount of time their teenager spends playing video games is in line with their peers,” Freed says.
While 71% of parents believe video games may have a positive impact on their teen, some (44%) try to restrict video game content. Parents of teens ages 13-15 (compared to those with older teens) are more likely to use rating systems to try to make sure games are appropriate (43% versus 18%), encourage their teen to play with friends in person rather than online and to ban gaming in their teen’s bedroom.
Parents polled also use different strategies to limit the amount of time their teen spends gaming, including encouraging other activities (75%), setting time limits (54%), providing incentives to limit gaming (23%) and hiding gaming equipment (14%).
Freed notes that while gaming may be a fun activity in moderation, some teens – such as those with attention issues – are especially susceptible to the constant positive feedback and the stimulus of video games. This may lead to prolonged play that is disruptive to other elements of a teen’s life.
He recommends parents show interest by playing video games with their kids while also communicating healthy limits and ensuring that they have strong privacy settings. In some situations, he notes, games can help parents connect with older kids and may occasionally help open the door to other conversations and interactions.
But parents should also help teens understand that limits and rules around gaming are tied to safety, health, school and relationships.
“Parents can play an important role by setting clear rules about appropriate content and how much time is too much time spent on video games,” Freed says.
“While many parents see benefits in gaming, the activity should not be at the expense of face-to-face time with family, friends, and teachers who play a pivotal role in promoting a teen’s learning and healthy development.”
The Mott Poll report is based on responses from 963 parents who had at least one child age 13-18 years.
For Valentine’s Day, we asked faculty and staff at nine CSU campuses to tell us how their lifelong love affair with their discipline began.
As the adage goes, “Choose a job you love, and you’ll never work a day in your life.” The CSU is lucky to be replete with faculty and staff across its 23 campuses who’ve found their true calling. And for those who work with them—whether students or colleagues—that dedication to education is infectious.
Read on to hear how faculty and staff at nine CSU campuses fell head over heels for their discipline.
ALICIA KINOSHITA | Ph.D., San Diego State, Associate Professor, Water Resources Engineering
When did your love of post-fire recovery take hold? “I started working in this field as an undergraduate research assistant taking samples and measurements of water and soil. The research also took me to amazing locations such as the Sierra Nevada and Colorado. I loved being outside rather than in an office, and when I realized I could do this for a living, I was sold.”
Why did you fall in love with it? “I really loved hiking and being outside. Glimpses of wildlife still fill me with awe and remind me that sometimes systems need to be reset. I also find great satisfaction in investigating the landscape after it has been disturbed and watching the changes over time. For example, after wildfire, it is amazing to watch a charred landscape evolve, from ash to green sprouts to dense vegetation.”
BRIAN SELF | Ph.D., Cal Poly San Luis Obispo, Professor, Mechanical Engineering, 2020 Wang Award Winner
When did your love of engineering take hold? “During my first year I took a survey course in biomedical engineering at Virginia Tech and really enjoyed it. As a result, I majored in a little-known department called engineering science and mechanics because it gave me the most flexibility to pursue biomedical types of courses. From there, I was able to get a job as a research engineer with the Air Force, where I investigated things like pilots pulling g’s [g-forces], ejections from aircraft and spatial disorientation.”
Why did you fall in love with it? “The human body is probably the most complex engineering system there is. As a civilian researcher, I got to use a human centrifuge to investigate human tolerances to sustained acceleration and to look at how high-altitude flight affects pilot performance. When I moved to Cal Poly, friends and I mentored senior design students as they developed devices to help people with disabilities participate in sports. I most love the amazing variety of interesting projects that I get to do, the wonderful colleagues I work with and the amazing students I get to mentor and teach.”
TED STANKOWICH | Ph.D., Cal State Long Beach, Director, The Mammal Lab
When did your love of animals take hold? “I began studying ecology and evolution early in college and then spent a summer vacation assisting with research on sharks. My junior year, I took a course in animal behavior and loved it. I then had the opportunity to work in one of the professor’s labs studying behavior in naked mole rats for my honors thesis.”
What is it about skunks? “They have this powerful noxious weapon everyone knows about, but…nobody studies their behavior. They are abundant and everyone seems to have a great skunk story to share. They are a misunderstood creature: They don’t stink themselves, aren’t aggressive, don’t ‘want’ to spray you and none of the large mammalian predators want anything to do with them!”
JOANNA PEREZ | Ph.D., CSU Dominguez Hills, Assistant Professor, Sociology
When did your love of sociology take hold? “As an undergraduate, learning about the sociological imagination—which is the connection between self and society—ignited my interest in the field. For the first time, I was able to critically analyze and contextualize my lived experiences as a first-generation student and daughter of immigrants. Today, I get to advocate for social justice through research, teaching and service.”
Why did you fall in love with it? “Sociology has allowed me to engage in efforts that alter the social conditions of marginalized communities. This includes conducting research on Latino undocumented immigrant activists, facilitating a student-centered learning environment and addressing the needs of underserved communities.”
COLIN DEWEY | Ph.D., Cal Maritime, Associate Professor, English
When did your love of English take hold? “After high school, I had no interest in higher education. Instead, I went on a road trip and visited the lighthouse at Point Arena in Northern California. The idea of becoming a lighthouse keeper led to a hitch in the U.S. Coast Guard; after my enlistment, I began sailing on commercial ships. I found an old volume of John Ruskin’s Victorian social commentary ‘Queen of the Air’ on board a freighter. In a later job, I had the opportunity to be a peer-tutor. When I went from solitary reading at sea to engaging others through tutoring, and then teaching, I recognized that sharing knowledge and helping others to reach the kinds of ‘Eureka!’ moments that I’d experienced with that Ruskin book was what I wanted to do.”
Why did you fall in love with it? “When I belatedly accepted the challenge and opportunity higher education held, I’d already spent close to 20 years working at sea. Education unlocked vast stores of knowledge unimaginable to my previous autodidact self. The recognition that I could help guide others along a path similar to the one I’d taken—regardless of their social or economic background—has become a vocation.”
BRIAN LEVIN | J.D., Cal State San Bernardino, Professor, Criminal Justice, Director, Center for the Study of Hate & Extremism, 2020 Wang Award Winner
When did your love of the study of civic cohesion and extremism take hold? “When Judge A. Leon Higginbotham taught me that a key component of the Brown vs. Board of Education decision was its partial reliance on social science data. From then on, I felt there was a place for informed research with respect to policymaking.”
Why did you fall in love with it? “When I first started in 1986, no one was collecting national data about hate crimes and there were no new anti-hate crime laws at the federal levels. Even the constitutionality of state laws was still in doubt. This created opportunities to influence public policy through participation in landmark cases, police training and legislative fact-finding. Through this, I represented civil rights groups before Congress and in various Supreme Court amici briefs. Getting involved so early gave me an up-close chance to learn from key mentors, to whom I am still indebted, while also advancing the discourse that illuminates public policy reform.”
ERIC BARTELINK | Ph.D., Chico State, Professor, Physical Anthropology
When did your love of anthropology take hold? “I realized this was my calling in 1995 when I was an undergraduate student in anthropology. I decided to shift my focus specifically to bioarchaeology and forensic anthropology after listening to some guest speakers.”
Why did you fall in love with it? “The idea that you can reconstruct several aspects of a person’s life from their skeleton always fascinated me, whether it was someone who died recently or hundreds or even thousands of years ago.”
LAURA LUPEI | Sonoma State, Senior Director, University Budget and Planning, 2020 Wang Award Winner
When did your love of budgeting take hold? “As soon as I started working at Somoma State 19 years ago, I knew it was a great fit. I spent every day solving problems and looking at both the details and the big picture of the university, something I hadn’t yet realized that came so naturally to me.”
Why did you fall in love with it? “I really fell in love with budgeting when we started our strategic budgeting initiative. Budgeting is a lot more fun when an organization uses it as a tool for planning and moving forward a set of priorities rather than reacting. It has been extremely satisfying to watch our campus culture shift, and I never thought so many people would be interested in listening to my budget presentations!”
RAJEE AMARASINGHE | Ph.D., Fresno State, Professor & Chair of Mathematics, 2020 Wang Award Winner
When did your love of math take hold? “After being injured as an officer in the Sri Lankan Navy, I was forced to rethink my future. Having this time to contemplate my next move, I remembered the love I had for mathematics as a child. This realization led me to pursue graduate studies in mathematics, where I would eventually begin conducting research in mathematics education. When I realized I could transform the lives of others through mathematics, I truly began to appreciate the work I was doing as a mathematics educator.”
Why did you fall in love with it? “Oftentimes, there are students and teachers who’ve never had that opportunity to see, feel and enjoy the beauty of mathematics. It’s such a joy when someone gets that ‘A-ha’ moment where they realize mathematics is beautiful and that they had fun engaging in it. I truly fell in love with the work I am doing when I realized that I could bring this joy to people every day.”
UNLV history professor Elizabeth Nelson separates facts about the effects of marketing, consumerism, and social media on the holiday’s evolution from fiction about love’s golden age.
Pets, spouses, co-workers, friends, classmates: They’re all in line to be on the receiving end of another record year for Valentine’s Day spending, says a new survey by the National Retail Federation.
But as Americans strive to return to the good old days of romance, one UNLV history professor says they never actually existed.
“People love the idea that there were these wonderful eras before our own time when people celebrated Valentine’s Day in the most authentic way,” says Elizabeth Nelson, a 19th-century pop culture expert, who began researching Valentine’s Day three decades ago and literally wrote the book on marketing the holiday. “But there was always this long and complicated history about Valentine’s Day and people actually thought that it was too commercial and insincere from the very beginning.”
We sat down with Nelson to get a handle on the history behind the holiday and the ways advertising, consumerism, and social media have changed the way we celebrate.
Who is St. Valentine and why does he have a holiday?
Popular lore says that in 5th century A.D., there was a St. Valentine who was imprisoned for some transgression. The myth says the jailer’s daughter took pity, brought him food, and tried to save him. The incarcerated man sent her a note of thanks, signing it: “From your Valentine.”
The story falls apart on multiple historical levels — it seems unlikely that the jailer’s daughter would have been literate or that Valentine could’ve gotten paper and pen in a jail cell. But historians argue that — like Christmas, Easter, and many other modern holidays — Christians in the past tended to link saint holidays with pagan celebrations to help solidify conversion because people didn’t want to give up the ways in which they lived their lives. Blending these holidays allowed revelers to keep observing rituals from centuries ago. Over time, the original intent was forgotten.
In this case, there was also a Roman festival called Lupercalia, celebrating fertility, that might have influenced the celebration of Valentine’s Day. While we now celebrate Valentine’s Day in February, in the Middle Ages, Chaucer, in “The Canterbury Tales,” describes the holiday as occurring in May with imagery of springtime, birds, and budding flowers — which makes sense if linked to a Roman holiday centered on fertility.
What’s more, there are several saints throughout history named Valentine. But none of them are patron saints of love.
Who celebrates Valentine’s Day and why?
Valentine’s Day is mostly only celebrated in the United States and Britain. Before the 18th century, it was about exchanging gifts — gloves and spoons were traditional — and being someone’s valentine for a whole year. It sometimes served as a precursor to betrothal.
There are some interesting stories circulating about why it’s not as popular overseas.
Legend has it that in France, women who were rejected by their desired valentine would burn those men in effigy in a bonfire, causing a riotous ruckus — so allegedly, the government outlawed Valentine’s Day in the early 19th century.
In England, there was a practice called “valentining,” where kids would go door to door asking for treats, similar to Halloween. However, over time, these public celebrations got out of hand and sometimes devolved into violence and mob action. So the proper, genteel middle class opted instead to change the focus from human interaction to the less dangerous exchange of cards.
When did the commercialization of Valentine’s Day begin?
In the 1840s, Valentine’s Day took off in the U.S. as increased paper production and printing presses lowered costs and increased the number of pre-printed cards that people could exchange that featured fancy lace, pictures, and other decorations. And sometimes celebrants copied pre-written poems out of books called “valentine writers” that featured bawdy sexual innuendo. My favorite metaphor: grating someone’s nutmeg.
One of earliest American valentine businesses was run by Esther Howland in Worcester, Mass. She was the daughter of an insurance agent who ran a stationary store. She asked her father to import fancy paper, lace, and other decor from England to make valentines to sell. She employed female friends of the family, and asked her brothers to share sample valentines during their work trips as traveling salesmen. Esther received many orders and created a successful business during the 1850s and 1860s. Her story is quite amazing because we don’t think of women as running businesses in the 19th century.
Hallmark was founded in 1911, and technology made it possible to produce valentines in color and with various textures even more inexpensively than before. So, it’s really in the beginning of the 20th century that Valentine’s Day becomes part of a general movement to turn holidays into opportunities for selling things from candy to flowers to magazine advertisements. Valentine’s Day began to center more on children than before. People began exchanging valentines in school. Hallmark played a big role in marketing it to elementary students, shifting the focus to the competitive collecting of the most valentines rather than a single sincere one.
Has romance always been at the center of Valentine’s Day?
Initially, it was about having one valentine throughout the year and possibly becoming betrothed. But it evolved in the 19th century, sparking questions about the sincerity of exchanging pre-printed cards and the sanity of spending exorbitant amounts of money on them.
Valentine’s Day and the exchange of valentines were a way that people in the emerging middle class in the 19th century negotiated that complicated relationship between romantic love and the economic reality of marriage. You could marry someone for love, but you still had to marry someone for love who could support you because most middle-class women didn’t work. So, it was dangerous just to fall in love with people without knowing anything about them. The celebration of Valentine’s Day became a way for people to test the uncomfortable juxtapositions of what love and marriage should be and the reality of what was actually possible. So, not so different from today.
How has social media shifted the celebration of Valentine’s Day?
One of the things that’s nice about Valentine’s Day today is that there are a variety of ways to celebrate. There are Galentine’s and Single Awareness Day celebrations, you can give your pet a gift, or you can even celebrate alone. You don’t have to wait for the candy or the flowers to come. People still do those things, but there’s less pressure to conform to a public declaration or celebration of it. And that’s the thing about Valentine’s Day: It’s about what other people see you doing or getting. How do you perform the idea of love rather than actually express or engage in the act of love. It’s the representation of the commercial items — getting flowers delivered to your office or going to a fancy restaurant or getting a piece of expensive piece of jewelry. It’s what other people think of your couplehood rather than what you think about it.
It is likely that Facebook and other social media have made Valentine’s Day more viral and more toxic, but the framework was already there. It’s not so much that social media really changed the scrutiny that was already at the core of Valentine’s Day; it just created a whole new possibility for performing the act of Valentine’s Day. Because social media sites are all about performing your imagined best self, the level of scrutiny on how you celebrate Valentine’s Day or what you got for Valentine’s day is ratcheted up exponentially on Facebook . It is not just about the people in your office or in your neighborhood, everybody in your world sees whether your sweetie did right by you or not, or vice versa.
Children’s of Alabama Expands Sensory Pathway For Patients With Sensory Sensitivities
When Sladen Fisher got a bad cut on his earlobe at school, his mother, Jennifer Fisher, worried the sights and sounds of Children’s of Alabama’s Emergency Department would be too stressful for her son. That’s because Sladen has attention deficit hyperactivity disorder (ADHD) and sensory processing disorder.
At the time of the Sladen’s visit, Children’s of Alabama had just launched its Sensory Pathway, designed for patients with conditions such as ADHD, autism and Down syndrome. In 2016, the pathway began as a pilot project in the Emergency Department; however, it has since expanded to One Day Surgery and several inpatient units at Children’s of Alabama, including the Pediatric Intensive Care Unit, Pulmonary Care Unit and Special Care Unit. Future plans include expansion to ancillary and outpatient services.
The pathway made a lasting impact on Sladen. Back at school a few weeks later, he presented a report about someone he considers a hero. He chose Children’s of Alabama Child Life Specialist Shelby Smith, who stayed by his side during his visit, explained his treatment in terms he understood and provided him with an iPad and fidget toys for distraction and comfort.
“In his mind, she was a hero, someone who went above and beyond to help him,” Jennifer said. She made what could have been an incredibly difficult situation so amazing. She really was our hero.”The pathway has been equally impactful on Children’s of Alabama, said Michele Kong, M.D. associate professor in pediatric critical care at the University of Alabama at Birmingham (UAB) Department of Pediatrics.
“The pathway has been so empowering for our providers,” said Kong, who serves on the Sensory Pathway Task Force, also comprised of nurses, informatics specialists and child life specialists. Unit by unit, the task force provides education and training and is developing an online training module. The task force is also working with information technology specialists to flag patients with sensory sensitivities from the point of admission.
“We tailor education and training to suit each unit’s needs because each unit’s workflow and culture is different,” Kong said. “The success of the pathway is a direct reflection of our providers’ passion to learn. There’s buy-in from our providers because they know it’s good for their patients.”
As a parent, Kong, too, knows how jarring a hospital visit can be for a child with sensory sensitivities. Her oldest son, Abram, was diagnosed with autism at age 4. The diagnosis inspired Kong and her husband, Julian Maha, M.D., to found KultureCity®, a nonprofit that works to “create acceptance and inclusion for all individuals with unique abilities,” according to its mission statement. In 2019, KultureCity was ranked fourth on Fast Company magazine’s list of the most innovative companies in the world. KultureCity not only partners with local organizations in Birmingham, but also with national organizations such as the NBA and NFL.
“We never imagined it would reach this scale,” Kong said. “It impressed on us that there’s a lot of power when a collective group of people have the same belief and passion for change.”
The rate of diagnosis for autism spectrum disorders (ASD) is the same among all racial groups — one in 110, according to current estimates. However, a study by a Florida State University researcher has found that African-American children tend to be diagnosed later than white children, which results in a longer and more intensive intervention. The reasons for later diagnoses include a lack of access to quality, affordable, culturally competent health care, according to Martell Teasley, an associate professor in Florida State’s College of Social Work who has conducted a comprehensive review of researchliterature on autism and African-American children. In addition, the stigmaattached to mental health conditions within the black community contribute to misdiagnoses of autism, and underuse of available treatment services.
“There are no subjective criteria for diagnosing autism. Only brain scans can truly provide appropriate diagnoses, because we are dealing with biological and chemical imbalances in the brain,” Teasley said. “Not every child is going to have access to this kind of medical evaluation, particularly those who are indigent and don’t have health care funding.”
Teasley examined ASD diagnosis and treatment strategies, and their effect on African-American families, in “Autism and the African-American Community,” a paper published in a special issue of the journal Social Work in Public Health (Vol. 26, Issue 4, 2011) that dealt with health-care policy issues in the black community related to the human genome.
Teasley co-wrote the paper with Ruby Gourdine, a professor of social work at Howard University in Washington, D.C., and Tiffany Baffour, an associate professor of social work at Winston-Salem State University in North Carolina. Because of the social stigma, Teasley says that some African-American families might be resistant to accept a diagnosis and treatment. “Less discussion about autism among African-Americans or between African-Americans and health care providers leads to misdiagnoses, a lack of treatment and a lack of services,” Teasley said.
“This will lead to greater challenges for families — more stress and anxiety, and poorer developmental outcomes.” African-Americans also might resist a diagnosis and treatment because of a mistrust of mainstream health care providers over past discrimination. “African-Americans are well versed in going to a doctor who might have biases or discriminatory practices, so they may not readily accept what a doctor says,” Teasley said. In addition, a cultural divide between African-Americans and mainstream health care providers can hinder a timely and correct diagnosis.
“There are not enough health care professionals who understand the cultural norms and attributes of the African-American community,” Teasley said. African-Americans live in all types of settings, but the majority live in urban areas, which have seen a decline in the number of mental-health care agencies since the 1980s. “This lack of accessibility causes a problem for some African-Americans,” Teasley said. Once a child is diagnosed with ASD, Teasley says both the child and the members of his or her family needs to receive appropriate training and counseling. “The children need behavioral counseling so they can develop the skills to live as independently as possible,” he said. “The families need to learn how to work with children who are autistic. “Intervention for any autistic child needs to start around age 3, so we can get the child to begin to learn how to eat right and develop normal, healthy routines, which will result in a better developmental outcome,” Teasley said. “Later intervention will result in a poorer developmental outcome that can have a lasting impact on the child’s and family’s quality of life.”
According to the American College of Obstetricians and Gynecologist, girls should have their first gynecologic visit between the ages of 13 and 15 years old.
Parents of young teenage girls are probably thinking about how to help them navigate social media, classwork, and their social lives. However, as young teenagers begin to go through puberty, it is also important to help them understand how to manage their changing bodies. Scheduling an appointment with a pediatric and adolescent gynecologist is one way to do this.
According to the American College of Obstetricians and Gynecologist, girls should have their first gynecologic visit between the ages of 13 and 15 years old. Pediatric and adolescent gynecology is a subspecialty of gynecology that provides comprehensive care for girls from birth to early adulthood. Pediatric and adolescent gynecologists take special care of the emotional needs of their patients and families while providing the unique care that’s necessary to foster the child’s transition from pediatrics to adult gynecology.
We spoke with pediatric gynecologist Amber Truehart, MD, about other reasons a girl should visit a gynecologist before she becomes an adult.
Education and Examinations
Patient education is one highlight of building a relationship with a pediatric and adolescent gynecologist. During the first visit, the doctor will help reinforce an understanding of healthy body weight and good habits for healthy bones. This is also an opportunity for young patients to learn about basic female hygiene, normal versus abnormal vaginal discharge, and puberty. Additionally, depending on the patient’s individual needs, their physical and emotional development, and medical history, the doctor may perform a basic physical exam, possibly including a breast exam.
Most girls get their first period when they are between 10 and 15 years old. So, it’s likely that a young girl is beginning to think about her period around this time. A visit with a pediatric and adolescent gynecologist will help her learn about the menstrual cycle and what is considered normal or abnormal. She can also learn how to manage her cycle, pain relief, and how to deal with premenstrual syndrome (PMS).
Young girls are able to get the HPV vaccine at their gynecologist’s office. The HPV vaccine helps protect children from developing the human papillomavirus, which can lead to six types of cancers later in life. The Centers for Disease Control and Prevention recommends two doses of the HPV vaccine, the first at age 11 and then six months later. If the child waits until age 15, they’ll need three doses of the vaccine.
Let’s face it — it may be difficult for a young girl to talk to a parent about sex. Yet, it’s important that she have an avenue for these conversations. Getting her in front of an expert she trusts will help her get accurate information and learn about sexually transmitted infections, HIV, and pregnancy prevention. She can also talk with her gynecologist about safe and healthy intimate relationships, LGBTQ topics and having sex for the first time.
For girls and young women who need complex gynecologic care, forming a doctor-patient relationship connects them with an expert who is poised to provide a full range of specialized services. Pediatric and adolescent gynecologists are trained to care for the intricate needs of children and teens who have physical or mental disabilities, congenital gynecologic abnormalities (present since birth), and underlying chronic health problems.
Research on the teeth of fossilized dinosaur embryos indicates that the eggs of non-avian dinosaurs took a long time to hatch–between about three and six months. The study, led by scientists at Florida State University, the American Museum of Natural History, and the University of Calgary, was published today in the Proceedings of the National Academy of Sciences and finds that contrary to previous assumptions, dinosaur incubation is more similar to that of typical reptiles than of birds. The work suggests that prolonged incubation may have affected dinosaurs’ ability to compete with more rapidly generating populations of birds, reptiles, and mammals following the mass extinction event that occurred 65 million years ago.
“We know very little about dinosaur embryology, yet it relates to so many aspects of development, life history, and evolution,” said study co-author Mark Norell, Macaulay Curator of Paleontology at the American Museum of Natural History. “But with the help of advanced tools like CT scanners and high-resolution microscopy, we’re making discoveries that we couldn’t have imagined 20 years ago. This work is a great example of how new technology and new ideas can be brought to old problems.”
Because birds are living dinosaurs, scientists have long assumed that the duration of dinosaur incubation was similar to birds, whose eggs hatch within 11 to 85 days. The research team tested this theory by looking at the fossilized teeth of two extremely well-preserved ornithischian dinosaur embryos on each end of the size spectrum: Protoceratops–a pig-sized dinosaur found by Norell and colleagues in the Mongolian Gobi Desert, whose eggs were quite small at 194 grams, or a little less than half of a pound–and Hypacrosaurus, a very large duck-billed dinosaur found in Alberta, Canada, with eggs weighing more than 4 kilograms, or nearly 9 pounds. First, the researchers scanned the embryonic jaws of the two dinosaurs with computed tomography (CT) at the Museum’s Microscopy and Imaging Facility to visualize the forming dentitions. Then they used an advanced microscope to look for and analyze the pattern of “von Ebner” lines–growth lines that are present in the teeth of all animals, humans included. This study marks the first time that these growth lines have been identified in dinosaur embryos.
“These are the lines that are laid down when any animal’s teeth develops,” said lead author and Florida State University professor Gregory Erickson. “They’re kind of like tree rings, but they’re put down daily. And so we could literally count them to see how long each dinosaur had been developing.”
Using this method, the scientists determined that the Protoceratops embryos were about three months old when they died and the Hypacrosaurus embryos were about six months old. This places non-avian dinosaur incubation more in line with that of their reptilian cousins, whose eggs typically take twice as long as bird eggs to hatch–weeks to many months. The work implies that birds likely evolved more rapid incubation rates after they branched off from the rest of the dinosaurs. The authors note that the results might be quite different if they were able to analyze a more “bird-like” dinosaur, like Velociraptor. But unfortunately, very few fossilized dinosaur embryos have been discovered.
“A lot is known about growth in dinosaurs in their juvenile to adult years,” said co-author Darla Zelenitsky, from the University of Calgary. “Time within the egg is a crucial part of development with major biological ramifications, but is poorly understood because dinosaur embryos are rare.”
The study also has implications for dinosaur extinction. Prolonged incubation exposed non-avian dinosaur eggs and attending parents to predators, starvation, and environmental disruptions such as flooding. In addition, slower embryonic development might have put them at a disadvantage compared to other animals that survived the Cretaceous-Paleogene extinction event.
Florida State University graduate student David Kay also is an author on this paper.

AMERICAN MUSEUM OF NATURAL HISTORY (AMNH.ORG)
The American Museum of Natural History, founded in 1869, is one of the world’s preeminent scientific, educational, and cultural institutions. The Museum encompasses 45 permanent exhibition halls, including the Rose Center for Earth and Space and the Hayden Planetarium, as well as galleries for temporary exhibitions. It is home to the Theodore Roosevelt Memorial, New York State’s official memorial to its 33rd governor and the nation’s 26th president, and a tribute to Roosevelt’s enduring legacy of conservation. The Museum’s five active research divisions and three cross-disciplinary centers support approximately 200 scientists, whose work draws on a world-class permanent collection of more than 33 million specimens and artifacts, as well as specialized collections for frozen tissue and genomic and astrophysical data, and one of the largest natural history libraries in the world. Through its Richard Gilder Graduate School, it is the only American museum authorized to grant the Ph.D. degree and the Master of Arts in Teaching degree. Annual attendance has grown to approximately 5 million, and the Museum’s exhibitions and Space Shows can be seen in venues on five continents. The Museum’s website and collection of apps for mobile devices extend its collections, exhibitions, and educational programs to millions more beyond its walls. Visit amnh.org for more information.
Without a doubt, Tyrannosaurus rex is the most famous dinosaur in the world. The 40-foot-long predator with bone crushing teeth inside a five-foot long head are the stuff of legend. Now, a look within the bones of two mid-sized, immature T. rex allow scientists to learn about the tyrant king’s terrible teens as well.
In the early 2000s, the fossil skeletons of two comparatively small T. rex were collected from Carter County, Montana, by Burpee Museum of Natural History in Rockford, Illinois. Nicknamed “Jane” and “Petey,” the tyrannosaurs would have been slightly taller than a draft horse and twice as long.
The team led by Holly Woodward, Ph.D., from Oklahoma State University Center for Health Sciences studied Jane and Petey to better understand T. rex life history.
The study “Growing up Tyrannosaurus rex: histology refutes pygmy ‘Nanotyrannus’ and supports ontogenetic niche partitioning in juvenile Tyrannosaurus” appears in the peer-reviewed journal Science Advances.
Co-authors include Jack Horner, presidential fellow at Chapman University; Nathan Myhrvold, founder and CEO of Intellectual Ventures; Katie Tremaine, graduate student at Montana State University; Scott Williams, paleontology lab and field specialist at Museum of the Rockies; and Lindsay Zanno, division head of paleontology at the North Carolina Museum of Natural Sciences. Supplemental histological work was conducted at the Diane Gabriel Histology Labs at Museum of the Rockies/Montana State University.
“Historically, many museums would collect the biggest, most impressive fossils of a dinosaur species for display and ignore the others,” said Woodward. “The problem is that those smaller fossils may be from younger animals. So, for a long while we’ve had large gaps in our understanding of how dinosaurs grew up, and T. rex is no exception.”
The smaller size of Jane and Petey is what make them so incredibly important. Not only can scientists now study how the bones and proportions changed as T. rex matured, but they can also utilize paleohistology– the study of fossil bone microstructure– to learn about juvenile growth rates and ages. Woodward and her team removed thin slices from the leg bones of Jane and Petey and examined them at high magnification.
“To me, it’s always amazing to find that if you have something like a huge fossilized dinosaur bone, it’s fossilized on the microscopic level as well,” Woodward said. “And by comparing these fossilized microstructures to similar features found in modern bone, we know they provide clues to metabolism, growth rate, and age.”
The team determined that the small T. rex were growing as fast as modern-day warm-blooded animals such as mammals and birds. Woodward and her colleagues also found that by counting the annual rings within the bone, much like counting tree rings, Jane and Petey were teenaged T.rex when they died; 13 and 15 years old, respectively.
There had been speculation that the two small skeletons weren’t T. rex at all, but a smaller pygmy relative Nanotyrannus. Study of the bones using histology led the researchers to the conclusion that the skeletons were juvenile T. rex and not a new pygmy species.
Instead, Woodward points out, because it took T. rex up to twenty years to reach adult size, the tyrant king probably underwent drastic changes as it matured. Juveniles such as Jane and Petey were fast, fleet footed, and had knife-like teeth for cutting, whereas adults were lumbering bone crushers. Not only that, but Woodward’s team discovered that growing T. rex could do a neat trick: if its food source was scarce during a particular year, it just didn’t grow as much. And if food was plentiful, it grew a lot.
“The spacing between annual growth rings record how much an individual grows from one year to the next. The spacing between the rings within Jane, Petey, and even older individuals is inconsistent – some years the spacing is close together, and other years it’s spread apart,” said Woodward.
The research by Woodward and her team writes a new chapter in the early years of the world’s most famous dinosaur, providing evidence that it assumed the crown of tyrant king long before it reached adult size.

Notre Dame Expert: Host of problems with Facebook deepfake ban
Tim Weninger, associate professor in the Department of Computer Science and Engineering at the University of Notre Dame, says Facebook’s newly announced ban on deepfakes is good news for democracy but presents a number of challenges in the fight against the spread of misinformation.
Weninger is an expert in disinformation and fake news, web and social media, data mining and machine learning.
“This is good news for democracy and a good business policy for Facebook, whose users don’t want to be lied to by the content they see,” Weninger said. “If Facebook becomes flooded by fake or misleading content, then users will abandon the site.”
But, Weninger adds, the policy presents a host of problems and challenges.
“Most obvious is the technological question of how will Facebook determine which content is AI faked and which is not. It’s clear that deepfake technology will soon be usable by the masses. And when that happens, Facebook won’t have the capacity to filter fake videos manually. Notre Dame and others are working on deepfake detectors, but these automatic detectors won’t catch everything.
“Second is the actual effect that this deepfake ban will have on the actual problem. It’s often said that ‘a lie can travel around the world before the truth can get its pants on.’ So, if a deepfake is created, shared and quickly taken down, the damage is done — it will live forever. And there is little that a maligned political candidate or brand can do to fix it.
“In my opinion, deepfakes are some mix of identity theft and slander. And there ought to be a legal remedy or judicial recourse available to the victims of deepfakes.”
