Being diagnosed with autism is often seen as a tragedy. But for Jac den Houting, it was the best thing that's ever happened to them. As an autistic person, concepts like the Neurodiversity paradigm, the Social Model of Disability, and the Double Empathy Problem were life-changing for Jac. In this talk, Jac combines these ideas with their own personal story to explain why we need to rethink the way that we understand autism. Jac den Houting is a research psychologist and Autistic activist in pursuit of social justice. Jac currently holds the role of Postdoctoral Research Associate at Macquarie University in Sydney, working alongside Professor Liz Pellicano. In 2015, Jac was awarded an Autism CRC scholarship to complete their PhD through the Autism Centre of Excellence at Griffith University in Brisbane. Prior to this, they gained almost 10 years’ experience as a psychologist in the criminal justice system, with the Queensland Police Service and Queensland Corrective Services. Jac was identified as Autistic at the age of 25, and is proudly neurodivergent and queer. After participating in the inaugural Future Leaders Program at the 2013 Asia Pacific Autism Conference, Jac quickly became established as a strong advocate for the Autistic community. Jac is a current member of the Autistic Self Advocacy Network of Australia and New Zealand (ASAN-AuNZ)’s Executive Committee, the Autism CRC’s Data Access Committee, Aspect’s LGBTQIA+ Autism Advisory Committee, and the Aspect Advisory Council. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

Have you ever come across times when you get particularly nervous, say during a presentation, you find it extra hard to speak smoothly? Most of us may stop at times when we talk, so how do we differentiate between Normal Dysfluency and Stuttering? Are kids struggling with words due to language ability or are they stuttering? Will they naturally outgrow stuttering? How do speech therapists help adults and children who stutter?
大家有否試過在某些時間特別緊張，例如在發佈會中，你覺得難以流暢地說話? 其實每一個人說話時也會有停頓的時候，到底我們如何分辨「口吃」和正常的不流暢呢？ 孩子到底是口吃還是因語言能力較弱而在找字呢？是否長大後自然會沒有口吃的問題？ 言語治療師可以如何幫助受口吃困擾的小孩和成人呢？

The traditional way of taking a drug, such as a pill or injection, often results in plasma drug levels that cycle between too high and too low. To better maintain drug levels in the effective range, scientists have developed a variety of systems to optimize drug release. In his first talk, Bob Langer gives an overview of many of these controlled drug release technologies, including polymer and pump systems. Langer begins Part 2 with the story of how he became interested in drug release technologies, which is also a story of the power of perseverance. As a post-doc with Judah Folkman, and after much trial and error, Langer developed a polymer system that provided a slow and constant release of an anti-angiogenesis factor. Initially, his results were met with skepticism, by both scientists and the patent office. Today, many, many companies have developed peptide delivery systems based on that original work. Langer also describes ongoing research in areas such as targeted drug delivery and externally controlled microchips designed for drug delivery. In Part 3, Langer focuses on the materials used in drug delivery and medical devices. Many of the original materials used in medicine were adapted from completely unrelated uses and often generated their own problems. Langer describes work by his lab and others to make polymers designed for specific medical uses. For instance, a porous polymer can be shaped into an ear or nose and act as a scaffold onto which a patient’s cells can be seeded to grow a new structure. Different polymers have been successfully used as scaffolds to grow new blood vessels or artificial skin for burn victims.

What if we looked at Parkinson's as an neurological electrical problem? Brain researcher Eleftheria Pissadaki and her team study dopamine neurons, the neurons that selectively die during Parkinson's. They discovered that the bigger a neuron is, the more vulnerable it becomes because it simply requires more energy. This new insight is reframing the disease -- and by "finding the fuse box for each neuron" and figuring out how much energy it needs, may help us neuroprotect our brain cells.

Irina Kareva translates biology into mathematics and vice versa. She writes mathematical models that describe the dynamics of cancer, with the goal of developing new drugs that target tumors. "The power and beauty of mathematical modeling lies in the fact that it makes you formalize, in a very rigorous way, what we think we know," Kareva says. "It can help guide us to where we should keep looking, and where there may be a dead end." It all comes down to asking the right question and translating it to the right equation, and back.

Easy access to nutrients has contributed to the increase in obesity in the human population. But, what is obesity and why isn’t everybody fat? Dr. Stephen O’Rahilly provides a biomedical perspective of obesity, and evaluates which genes could potentially shift the balance towards obesity. As he explains, one becomes obese when the balance between energy intake and energy spent is shifted. Surprisingly, mutations that lead to obesity in humans aren’t in genes involved in metabolism and energy storage, but failure in satiety signals in the brain that result in people eating too much. The excess of energy intake over energy expenditure leads to obesity. What is the consequence of obesity in human health? Physically, obesity can result in lower mobility and sleeping disorders. But, in humans, the link between obesity and metabolic diseases isn’t straightforward. For example, not everyone that’s obese becomes insulin resistant. As O’Rahilly explains, the probability of an obese individual to have a metabolic disease is linked to the capacity of adipose tissue to store the extra fat. Mutations that decrease fat storage in adipose tissue increase the chance of metabolic diseases, like insulin resistance, even when the person is not obese.

Childhood trauma isn’t something you just get over as you grow up. Pediatrician Nadine Burke Harris explains that the repeated stress of abuse, neglect and parents struggling with mental health or substance abuse issues has real, tangible effects on the development of the brain. This unfolds across a lifetime, to the point where those who’ve experienced high levels of trauma are at triple the risk for heart disease and lung cancer. An impassioned plea for pediatric medicine to confront the prevention and treatment of trauma, head-on.

What if you could know exactly how food or medication would impact your health -- before you put it in your body? Genomics researcher Jun Wang is working to develop digital doppelgangers for real people; they start with genetic code, but they'll also factor in other kinds of data as well, from food intake to sleep to data collected by a "smart toilet." With all of this valuable information, Wang hopes to create an engine that will change the way we think about health, both on an individual level and as a collective.

Once a cared-for patient and now a caregiver himself, Scott Williams highlights the invaluable role of informal caregivers -- those friends and relatives who, out of love, go the extra mile for patients in need. From personal care to advocacy to emotional support, unpaid caregivers form the invisible backbone of health and social systems all over the world, Williams says -- and without them, these systems would crumble. "How can we make sure that their value to patients and society is recognized?" he asks.

What does the health of a region's animal population say about the health of the local humans? More than you'd think, argues Tracey McNamara. As an expert in zoonotics -- the study of diseases that can be transmitted between animals and humans -- McNamara explains how paying attention to animal disease patterns could have predicted events like the 1999 West Nile Virus outbreak and stresses the need for global health agencies to start monitoring animals just as closely as they do people.

In the US, the very same blood test can cost $19 at one clinic and $522 at another clinic just blocks away -- and nobody knows the difference until they get a bill weeks later. Journalist Jeanne Pinder says it doesn't have to be this way. She's built a platform that crowdsources the true costs of medical procedures and makes the data public, revealing the secrets of health care pricing. Learn how knowing what stuff costs in advance could make us healthier, save us money -- and help fix a broken system.

The US health care system assumes many things about patients: that they can take off from work in the middle of the day, speak English, have a working telephone and a steady supply of food. Because of that, it's failing many of those who are most in need, says Mitchell Katz, CEO of the largest public health care system in the US. In this eye-opening talk, he shares stories of the challenges low-income patients face -- and how we can build a better system for all.

We are two sisters on a mission to demystify science with humor and relevance by creating videos, GIFs, comics, and resources. Our content is focused on high school biology (Pinky is a former high school biology teacher), though we do receive comments that some of our content is useful for intro biology courses at the college level as well. We're for anyone wanting to learn biology! We frequently remind viewers that we cannot include all of the fascinating exceptions and details in a video under 10 minutes. We like to create memorable visuals to the content, but they're not scientific illustrations. Meaning, nitrogen and carbon don't tap dance. Our illustrated cell and molecule cartoons are definitely not to scale. DNA is usually a right-handed double helix (well...there are exceptions) and it doesn't have eyes...a face...or a top hat...

Now that we know about muscle tissue, let's see how this is arranged to form the muscular system, the incredible network of muscles that covers the skeletal system so that it can pull on bones and allow us to move around at will. There are hundreds of muscles so we won't cover them all, but we will learn some basic ways of categorizing and naming them, and take a look at a bunch of them too!
