Developing humanoid robots, unravelling the complexities of AI, and the mysteries of consciousness.

Welcome to the ⁠⁠⁠North of Patient⁠⁠⁠ podcast — conversations on health[beyond]care — where we paint an inspired landscape of healthcare’s future through dialogues with creative and unconventional thinkers from around the world.

For a summary of the episode, visit the ⁠blog post⁠ on North of Patient:

This week’s guest is the remarkable Dr. Suzanne Gildert. She’s a physicist, artist, and AI tech executive based in Vancouver on a mission to uncover the mysteries of consciousness and innovate unconscious AI.

In this episode, we dive into the groundbreaking advancements and pressing challenges in quantum computing, examining the transformative potential of these technologies to reshape our world. Beyond the science, we also explore the philosophical dimensions of AI consciousness, questioning whether AI can ever truly replicate human experience and identity.

Whar may happen when the first truly smart robots appear, based on brain emulations or ems. Scan a human brain, then run a model with the same connections on a fast computer, and you have a robot brain, but recognizably human.

Train them to do some job and copy it a million times: an army of workers is at your disposal. When they can be made cheaply.
within perhaps a century, they will displace humans in most jobs.
In this new economic era, the world economy may double in size every few weeks.
Applying decades of expertise in physics, computer science, and economics.
and use ofstandard theories indicate a detailed picture of a world dominated by ems.

His major fields of interest include health policy, regulation, and formal political theory. Recent book: The Age of Em: Work, Love and Life When Robots Rule The Earth.

This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

For the first time, surgeons have successfully performed a remarkable new heart transplant in which the donor organ never skips a beat in the process, reducing the damage that can occur during such a complex operation. It ushers in a new era of more successful heart transplant surgery.

A team of surgeons at the National Taiwan University Hospital (NTUH) in Taipei undertook the revolutionary operation, during which the donor heart continues beating between the organ removal and transplantation stages. Traditionally, the donor heart would be removed and preserved in cold storage to reduce its workload – during this stage, it’s considered “ischemic time,” or the period during which the organ is cut off from blood supply. This comes with the risk of heart damage and rejection once it’s transplanted into a recipient.

When the heart is deprived of blood, ischemia – a shortage of oxygen – can damage its muscle tissue, or myocardium, reducing function and health once it is transplanted. While an organ set for transplant rarely endures more than a few hours in ischemic time, it can still lead to myocardial damage.

Measles, a highly contagious viral infection, continues to pose a significant public health threat worldwide. Despite the availability of effective vaccines, outbreaks persist, particularly in regions with low immunization rates. In 2023, the World Health Organization observed up to a 30-fold increase in measles cases in Europe. There are currently no treatment options for measles. Instead, patients must allow the virus to take its course and let the immune system naturally clear the infection.

Erica Ollmann Saphire, a structural biologist, and her research team at the La Jolla Institute for Immunology uncovered the structure of the measles glycoprotein and engineered a neutralizing antibody against it. This therapy could be implemented to manage measles outbreaks worldwide.

Researchers uncovered the structure of the measles fusion glycoprotein and identified a neutralizing antibody capable of decreasing its virulence.

As of October 2024, 3,000 patients had used Piction’s clinic. So far, it is available in Connecticut, Florida, Massachusetts, New Hampshire and Washington. The service is covered by several major insurance companies, or patients can pay $119 out-of-pocket for each consultation.

Eleni Linos, a professor of dermatology and epidemiology who directs the Stanford Center for Digital Health, and who has no connection with Piction, says: “I’m really optimistic about how this technology can help patients get the best care they can get, while at the same time helping doctors.” — Esther Landhuis.

Both the injectable and oral forms of semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist, have recently gained attention for their effectiveness in managing weight gain, high blood sugar, and even reducing alcohol cravings.

A new clinical trial, co-led by endocrinologist and diabetes specialist John Buse, MD, PhD, and interventional cardiologist Matthew Cavender, MD, MPH, at the UNC School of Medicine, has demonstrated that the oral form of semaglutide significantly lowers the risk of cardiovascular events in individuals with type 2 diabetes, atherosclerotic cardiovascular disease.

Cardiovascular disease (CVD) encompasses a range of disorders affecting the heart and blood vessels, including coronary artery disease, heart attack, stroke, and hypertension. These conditions are primarily driven by atherosclerosis, a process where plaque builds up in the arterial walls, leading to narrowed or blocked arteries. Risk factors include smoking, unhealthy diet, lack of exercise, obesity, and genetic predisposition. CVD remains a leading cause of global mortality, emphasizing the importance of lifestyle changes, medical interventions, and preventive measures in managing and reducing the risk of heart-related illnesses.

A new discovery could pave the way for more effective cancer treatment by helping certain drugs work better inside the body. Scientists at Duke University School of Medicine, University of Texas Health Science Center at San Antonio, and University of Arkansas have found a way to improve the uptake of a promising class of cancer-fighting drugs called PROTACs, which have struggled to enter cells due to their large size.

The new method works by taking advantage of a protein called CD36 that helps pull substances into cells. By designing drugs to use this CD36 pathway, researchers delivered 7.7 to 22.3 times more of the drug inside , making the treatment up to 23 times more potent than before, according to the study published April 17 in Cell.

Data from mouse studies shows this enhanced uptake led to stronger tumor suppression without making the drugs harder to dissolve or less stable.

Exercise for a long period of time forces the human body to resort to its energy reserves. When running a marathon, for example, the body mainly consumes carbohydrates, such as glycogen, as a source of energy, but it resorts to fats when the glycogen in the muscles is used up. Myelin, which surrounds neurons in the brain and acts as an electrical insulator, mainly comprises lipids, and previous research in rodents suggests that these lipids can act as an energy reserve in extreme metabolic conditions.

A study conducted by researchers shows that people who run a marathon experience a decrease in the amount of myelin in certain regions of the brain. According to the study published by Nature Metabolism, this effect is completely reversed two months after the marathon.

The researchers used magnetic resonance imaging to obtain images of the brains of ten marathon runners (eight men and two women) before and 48 hours after the 42-kilometre race. Likewise, the researchers took images of the brains of two of the runners two weeks after the race, and of six runners two months after the race as a follow-up.
