Many Worlds of Quantum Theory

Make a donation to Closer To Truth to help us continue exploring the world’s deepest questions without the need for paywalls: https://shorturl.at/OnyRq.

Quantum theory is very strange. No act is wholly sure. Everything works by probabilities, described by a wave function. But what is a wavefunction? One theory is that every possibility is in fact a real world of sorts. This is the Many Worlds interpretation of Hugh Everett and what it claims boggles the brain. You can’t imagine how many worlds there would be.

Nuclear waste could be a source of fuel in future reactors

Terence Tarnowsky, a physicist at Los Almos National Laboratory (LANL), will present his results at the fall meeting of the American Chemical Society (ACS). ACS Fall 2025 is being held Aug. 17–21; it features about 9,000 presentations on a range of science topics.

FOR IMMEDIATE RELEASE

WASHINGTON, Aug. 18, 2025 — From electric cars to artificial intelligence (AI) data centers, the technologies people use every day require a growing need for electricity. In theory, nuclear fusion — a process that fuses atoms together, releasing heat to turn generators — could provide vast energy supplies with minimal emissions. But nuclear fusion is an expensive prospect because one of its main fuels is a rare version of hydrogen called tritium. Now, researchers are developing new systems to use nuclear waste to make tritium.

This Protein Slows the Aging Brain, and We Know How to Counter It

Aging is particularly harsh on the hippocampus, the brain region responsible for learning and memory.

Now, researchers at UC San Francisco have identified a protein that’s at the center of this decline.

They looked at how the genes and proteins in the hippocampus changed over time in mice and found just one protein that differed between old and young animals. It’s called FTL1. Old mice had more FTL1, as well as fewer connections between brain cells in the hippocampus and diminished cognitive abilities.

Scientists discover a protein that gets concentrated in the brain during aging, leading brain connections to wither and cognitive decline to accelerate — and a way to counter its effects.

How Dr. Bill Andrews Plans to Cure Aging in 3 Years

Anybody got a spare $130 million?

Dr. Bill Andrews, a trailblazing scientist, is on a mission to cure aging. From a childhood dream sparked at age 10 to his pioneering telomerase research, he reveals how Sierra Sciences could reverse aging in just three years with $130 million in funding. Yet, investor demands for quick returns stand in his way.
He believes that a Biotech Freedom Zone through Immortalis—a revolutionary approach to bypass funding and regulatory hurdles—is the catalyst to transform longevity research, making health affordable and aging a thing of the past.

Effects of The Legend of Zelda: Breath of the Wild and Studio Ghibli Films on Young People’s Sense of Exploration, Calm, Mastery and Skill, Purpose and Meaning, and Overall Happiness in Life: Exploratory Randomized Controlled Study

Background: Young people feel increasingly anxious and sad nowadays. Engaging with works of art and entertainment, such as playing open-world games or watching Studio Ghibli films, can be more than just a pastime. However, the extent to which, if at all, open-world games and feelings of nostalgia affect overall happiness in life remains unclear.

Objective: This study aimed to examine the extent to which open-world games, such as The Legend of Zelda: Breath of the Wild, and nostalgia evoked by Studio Ghibli films, such as Hayao Miyazaki’s My Neighbor Totoro or Kiki’s Delivery Service, affect postgraduate students’ sense of exploration, calm, mastery and skill, purpose and meaning, and, ultimately, happiness in life.

Methods: A controlled laboratory experiment was conducted using a 2 (playing an open-world game vs no open-world game) × 2 (nostalgia vs no nostalgia) between-subject design. Study participants (N=518) were randomly assigned to the study’s 4 conditions and answered a brief questionnaire, examining their sense of exploration, calm, mastery and skill, purpose and meaning, and, ultimately, happiness in life. As part of the study, we conducted univariate analysis and bootstrapping-based moderated mediation analysis with 5,000 resamples.
