Anna Lembke is professor of psychiatry at Stanford University School of Medicine and chief of the Stanford Addiction Medicine Dual Diagnosis Clinic. A clinician scholar, she has published more than a hundred peer-reviewed papers, book chapters, and commentaries.
Psychiatrist and author Dr. Anna Lembke discusses dopamine, addictive behaviors, warning signs and treatment for addiction, and how our brains handle all that pleasure and pain in life. Dr. Lembke is a professor of psychiatry at Stanford University School of Medicine and chief of the Stanford Addiction Medicine Dual Diagnosis Clinic. She appeared in the 2020 Netflix documentary The Social Dilemma to discuss the addictive nature of social media, and she is the author of the 2021 New York Times bestseller Dopamine Nation: Finding Balance in the Age of Indulgence, which explores how to moderate compulsive overconsumption in a dopamine-overloaded world.
Personal growth and success require a focus on emotional intelligence, individualized practices, and a shift away from material desires and instant gratification.
Questions to inspire discussion.
What is the key to success?
—The key to success is not just high IQ, but also emotional intelligence, self-awareness, and understanding oneself as a human instrument, which can lead to improvement in all aspects of life.
Dr. Alok Kanojia (Dr. K) is a psychiatrist, Harvard Medical School instructor, co-founder of HealthyGamerGG, Twitch streamer and a YouTuber. Humans face a predicament that has never been seen in our history, a massive overload in daily stimulation and information. The effect of constant exposure to social media, video games, and porn is not good, but thankfully there are a number of powerful ways to take back control of your attention. Expect to learn the correlation between video game usage and mental health, why our brains are uniquely addicted to looking at screens, whether dopamine fasting is actually legit, the problem with watching porn at a young age, how to combat screen addiction, why some people always feel like they have brain fog, how to find meaning in your life and much more…
Summary: Experienced meditators can voluntarily induce unconscious states, known as cessations, without the use of drugs. This ability, observed in Tibetan Buddhist practice, allows meditators to experience a momentary void of consciousness, followed by enhanced mental clarity.
Conducted across multiple countries, the study utilized EEG spectral analysis to objectively measure brain activity during these cessation events. By correlating the meditator’s first-person experience with neuroimaging data, researchers have gained insights into the profound modulation of consciousness achievable through advanced meditation practices.
The digital twin system created by Zhang, Ji, and their colleagues creates a virtual replica of a scene in which a human and robot agent are collaborating.
Robotics systems have already been introduced in numerous real-world settings, including some industrial and manufacturing facilities. In these facilities, robots can assist human assembly line and warehouse workers, assembling some parts of products with high precision and then handing them to human agents tasked with performing additional actions.
In recent years, roboticists and computer scientists have been trying to develop increasingly advanced systems that could enhance these interactions between robots and humans in industrial settings. Some proposed solutions rely on so-called ‘digital twin’ systems, virtual models designed to accurately reproduce a physical object, such as specific products or components that are being manufactured.
Researchers at Nanjing University of Aeronautics and Astronautics in China recently introduced a new digital twin system that could improve the collaboration between human and robotic agents in manufacturing settings. This system, introduced in a paper published in Robotics and Computer-Integrated Manufacturing, can create a virtual map of real-world environments to plan and execute suitable robot behaviors as they cooperate with humans on a given task.
The SpaceX Falcon 9 rocket is the vehicle that brings satellites, Dragon cargo spacecraft and Crew Dragon spacecraft to orbit.
Among its many uses, SpaceX regularly launches Falcon 9 to bring its Dragon spacecraft to the International Space Station. Dragon made the first private spacecraft visit ever there in October 2012 and has run more than 25 cargo missions in the years since. Since 2020, SpaceX also used Falcon 9 for crewed missions to the ISS, on behalf of NASA and other customers.

Northwestern University researchers have developed the first physics-based metric to predict whether or not a person might someday suffer an aortic aneurysm, a deadly condition that often causes no symptoms until it ruptures.
In the new study, the researchers forecasted abnormal aortic growth by measuring subtle “fluttering” in a patient’s blood vessel. As blood flows through the aorta, it can cause the vessel wall to flutter, similar to how a banner ripples in the breeze. While stable flow predicts normal, natural growth, unstable flutter is highly predictive of future abnormal growth and potential rupture, the researchers found.
Called the “flutter instability parameter” (FIP), the new metric predicted future aneurysm with 98% accuracy on average three years after the FIP was first measured. To calculate a personalized FIP, patients only need a single 4D flow magnetic resonance imaging (MRI) scan.
Galactic winds enable the exchange of matter between galaxies and their surroundings. In this way, they limit the growth of galaxies, that is, their star formation rate. Although this had already been observed in the local universe, an international research team led by a CNRS scientist1 has just revealed — using MUSE, 2 an instrument integrated into the European Southern Observatory’s (ESO) Very Large Telescope — the existence of the phenomenon in galaxies which are more than 7 billion years old and actively forming stars, the category to which most galaxies belong.
The team’s findings, to be published in Nature on 6 December 2023, thus show this is a universal process.
Galactic winds are created by the explosion of massive stars.
