The 200th episode of Mindscape! Thanks to everyone for sticking around for this long. To celebrate, a solo episode discussing a set of issues naturally arising at the intersection of philosophy and physics: how to think about probabilities and expectations in a multiverse. Here I am more about explaining the issues than offering correct answers, although I try to do a bit of that as well.

Summary: A new study reveals that individuals with stronger ‘mindreading’ abilities, or the capacity to understand others’ feelings and intentions, are more successful in cooperative tasks. This trait, also known as ‘theory of mind,’ is not directly tied to intelligence and can potentially be improved through training programs.

The research demonstrated that those with high theory of mind were more effective in cooperation, particularly when paired with individuals with similar abilities. The study underlines the potential to foster enhanced cooperation in various settings like schools, workplaces, or colleges by improving these abilities.

In this talk we introduce Shivon Zilis, Project Director at Neuralink, to her team’s work and the ethical impacts of implanting technology into the brain. We learn about the latest developments in Neuralink’s technology and the goals the team keeps in mind when designing and implementing technology that could change the way humans interact and understand technology.

Researchers have managed to decode an ancient script that scholars have been unable to understand for decades.

In a study published in the journal Transactions of the Philological Society, a team of scientists describe how they partially deciphered the “unknown” Kushan script, an ancient writing system that was once in use in parts of Central Asia between around 200 B.C. and 700 A.D.

It has been associated with early nomadic peoples of the Eurasian steppe, such as the Yuèzhī, and one of their ruling dynasties, the Kushans, who founded a large empire encompassing much of what is now Uzbekistan, Afghanistan, Pakistan and northern India.

Summary: A new study suggests that ChatGPT’s healthcare-related responses are hard to distinguish from those provided by human healthcare providers.

The study, involving 392 participants, presented a mix of responses from both ChatGPT and humans, finding participants correctly identified the chatbot and provider responses with similar accuracy.

However, the level of trust varied based on the complexity of the health-related task, with administrative tasks and preventive care being more trusted than diagnostic and treatment advice.

Research led by Sichuan University and Huazhong University of Science and Technology, China, has revealed genetic mechanisms that could prolong healthy aging. In the paper, titled “Partial inhibition of class III PI3K VPS-34 ameliorates motor aging and prolongs health span,” published in PLOS Biology, the team details the methods they used to narrow down the potential genomic pathways to a single gene that could be critical to extending healthy human longevity.

With a combination of genetic manipulation, behavioral assays, microscopy techniques, and electrophysiology, the researchers investigated the role of VPS-34 in aging. These methods allowed the researchers to gain insights into the underlying motor aging and the effects of VPS-34 on , synaptic transmission, and muscle integrity.

According to the authors, increased in recent decades has not been accompanied by a corresponding increase in health span. Aging is characterized by the decline of multiple organs and tissues and motor aging, in particular, leads to frailty, loss of motor independence, and other age-related issues. Identifying mechanisms for therapeutics to delay motor aging is crucial for promoting .

Summary: Researchers have uncovered genes essential for learning, memory, aggression, and other complex behaviors originated around 650 million years ago.

The study utilized computational methods to trace the evolutionary history of these genes involved in the production, modulation, and reception of monoamines like serotonin, dopamine, and adrenaline. This discovery suggests that this new method of modulating neuronal circuits could have played a role in the Cambrian Explosion, contributing to the diversification of life.

The finding offers new research avenues to understand the origins of complex behaviors and their relation to diverse processes like reward, addiction, aggression, feeding, and sleep.
