Immune to Cancer | Michael Jensen | TEDxStMarksSchool

What if the future of cancer treatment lies not with stronger drugs and larger doses of radiation that kill cells indiscriminately, but instead harnesses the power of our immune system to destroy cancer cells in our own body? Dr. Michael Jensen shares details of an FDA approved cancer treatment with a 91% cure-rate.

Dr. Michael Jensen is a leader in the field of cancer immunotherapy research. As the founding director of the Ben Towne Center for Childhood Cancer Research at Seattle Children’s Research Institute, Dr. Jensen and his team are pioneering translational research with striking results that just might change the way we think of disease treatment.

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

The Fork in the Road for the Future of Humanity

On 25 September 2019, Steve Fuller gave a Codex Talk at the Royal Society of London, commemorating the ‘world’s top 50 innovators’ on the 500th anniversary of the death of Leonardo da Vinci. Da Vinci authored the ‘Codex’ in question, which is a notebook of his thoughts, including a drawing of ‘Vitruvian Man’, which begins Fuller’s talk.

The ‘fork in the road for the future of humanity’ refers to transhumanism and posthumanism, which Fuller treats as projecting radically alternative visions for the human condition.

First Ever Double-Slit Experiment Performed with Antimatter

Positrons traverse two circular 2-mm-wide collimators 10.2 cm apart. The interferometer is composed of two SiN diffraction gratings with periodicity d1 and d2, respectively, separated by L1 = (118.1 ± 0.2) mm. Interference fringes with d3 periodicity are expected at L2 = (576 ± 5) mm. The emulsion is tilted so that the Y axis in the reference frame of the emulsion surface (X, Y) forms a 45° angle with the y axis of the laboratory. Gamma rays (511 keV) from positron annihilation in the emulsion are monitored with a high-purity germanium (HpGe) detector for rate measurement.

Tonight will be the darkest night of the past 500 years

Thanks to a lunar eclipse on the longest night of the year, tonight we’ll be experiencing the longest, darkest night in a very long time. It’s been nearly 500 years since the last solstice lunar eclipse. Here’s what you’ll see.

Is Anticipation a Good Strategy?

Anticipation and to remain hopeful and patient in expecting a preferred future have a special place and a critical role in some moral and religious systems of faith. As a personal virtue, there are many natural, cultural, social, and educational factors that play a role in its development. However, for an economic agent and in general forward looking decision makers who follow a more secular worldview, the argument in favor of anticipation and how much it could be reasonable might be less clear. Therefore, it is worthwhile to explore when and under which circumstances we should choose anticipation. A convincing argument might be helpful. In this blog post I will build a framework based on game theory to provide a better and deeper insight.

Economists, mathematicians, and to some degree, engineers have contributed to the development of game theory. In neoclassic economics, it is assumed that each economic agent has a rational behavior. According to the prediction model based on such an assumption, decision makers, if they sell goods and services, tend to maximize profit and if they buy tend to maximize utility. In other words, people naturally seek the best and the most. Moreover, decision making is based on the principle of “predict then act”. The individual first predicts the likely consequences of choices and attribute to them utilities. In the next step, an alternative is chosen that has the best consequence or the most utility. This camp or school is often called the normative decision analysis.

Nonetheless, empirical studies on the behavior of real decision makers demonstrate that despite the prediction of rational models of choice, the individuals or economic agents, do not always follow the principle of the best and the most. In 1950s, for instance, Herbert Simon showed that when faced with uncertainty and due to lack of information about the future, there are cognitive limits to rationality such that contrary to the neoclassic economic theory, people do not make decisions rationally and logically in search of the optimal alternative. Instead they seek a combination of satisfaction and sufficing levels of utility which is also called “satisficing”. This camp or school is often called the behavioral or descriptive decision analysis. To further explain, no one can claim that in a certain decision the best alternative has been chosen, regardless of the choice criteria or the ideal level of utility. Because there is always a better alternative than the best alternative known to us now. That better alternative either exists now beyond our awareness or will appear in the future. But we never can choose it if we do not know about it. In brief, we can possibly choose from a subset of the best, the best element.

In light of the flaws of the actual decision making by humans, we tend to recognize both the pros and cons of normative and descriptive decision analysis. Pioneers of decision analysis therefore have attempted to work on a new integral school that is wise enough and take into account the natural cognitive limits. This camp or school is often called the “prescriptive” decision analysis. The aim is to educate and train better decision makers, both individually and collectively. Our approach here to the question of anticipation is also integral and prescriptive.
