Alzheimer’s and dementia are a heart-breaking reality for millions across the world. Find out what inventors and scientists on the cutting edge of medical research are doing to combat this neurological puzzle.

TED Fellow and equity bioengineer Erika Moore investigates how cells controlling inflammation behave differently depending on a patient's background. By focusing on the "who" behind the disease, Moore is uncovering why certain diseases disproportionately affect certain ethnicities, paving the way for more inclusive and effective health care.

Roger Stein wants to bring financial engineering to the world of drug funding.

It's time to make psychiatry more psychedelic, says psychiatrist Benjamin Lewis. Sharing results from his clinical trial on psychedelic-assisted therapy, he highlights how group therapy paired with the safe use of psilocybin, a compound found in magic mushrooms, has the potential to improve mental health conditions like depression and burnout.

Antibiotics: behind the scenes, they enable much of modern medicine. We use them to cure infectious diseases, and to safely facilitate everything from surgery to chemotherapy to organ transplants. But we've stopped discovering new ones and we're at risk of losing them forever. How did we get into this situation? Gerry Wright shares what we can d...

Russ Altman uses machine learning to better understand adverse effects of medication.

Danny Hills makes a case for the next frontier of cancer research: proteomics, the study of proteins in the body. As Hillis explains it, genomics shows us a list of the ingredients of the body -- while proteomics shows us what those ingredients produce. Understanding what's going on in your body at the protein level may lead to a new understandi...

When you're getting medical treatment, or taking part in medical testing, privacy is important; strict laws limit what researchers can see and know about you. But what if your medical data could be used -- anonymously -- by anyone seeking to test a hypothesis? John Wilbanks wonders if the desire to protect our privacy is slowing research, and if...

Marie Skłodowska Curie's revolutionary research laid the groundwork for our understanding of physics and chemistry, blazing trails in oncology, technology, medicine, and nuclear physics, to name a few. But what did she actually do? Shohini Ghose expounds on some of Marie Skłodowska Curie's most revolutionary discoveries. [Directed by Anna Nowako...

Nina Tandon is CEO and co-founder of EpiBone. She studies ways to use electrical signals to grow artificial tissues for transplants and other therapies.

Surgery, chemotherapy and radiation are the best-known methods for treating cancer. At TEDMED, Bill Doyle presents a new approach, called Tumor Treating Fields, which uses electric fields to interrupt cancer cell division. Still in its infancy -- and approved for only certain types of cancer -- the treatment comes with one big benefit: quality o...

A professor of chemistry, nanoscience and chemical complexity, Lee Cronin and his research group investigate how chemistry can revolutionize modern technology and even create life.

Samuel Cohen researches Alzheimer's disease and other neurodegenerative disorders.

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 t...
