From noise to power: A symmetric ratchet motor discovery

Vibrations are everywhere—from the hum of machinery to the rumble of transport systems. Usually, these random motions are wasted and dissipated without producing any usable work.

Recently, scientists have been fascinated by “ratchet systems,” which are that rectify chaotic vibrations into directional motion. In biology, molecular motors achieve this feat within living cells to drive the essential processes by converting random molecular collisions into purposeful motions. However, at a large scale, these ratchet systems have always relied on built-in asymmetry, such as gears or uneven surfaces.

Moving beyond this reliance on asymmetry, a team of researchers led by Ms. Miku Hatatani, a Ph.D. student at the Graduate School of Science and Engineering, along with Mr. Junpei Oguni, graduate school alumnus at the Graduate School of Science and Engineering, Professor Daigo Yamamoto and Professor Akihisa Shioi from the Department of Chemical Engineering and Materials Science at Doshisha University, demonstrate the world’s first symmetric ratchet motor.

The Different Relationships Between Mobile Phone Dependence and Adolescents’ Scientific and Artistic Creativity: Self‐Esteem and Creative Identity as Mediators

Creativity is the ability to generate original, useful, and meaningful ideas or solutions by combining imagination with knowledge and experience. It involves flexible, divergent thinking and seeing connections that others might overlook.

Artistic creativity refers to expressing ideas, emotions, or concepts through mediums such as painting, music, writing, or performance, emphasizing aesthetic and emotional impact.

Scientific creativity, on the other hand, involves problem-solving, hypothesis generation, and innovative experimentation that can advance knowledge or technology.

The Different Relationships Between Mobile Phone Dependence and Adolescents’ Scientific and Artistic Creativity: Self-Esteem and Creative Identity as Mediators.

Creativity is an essential skill that is at the heart of 21st-century education. Mobile phone use occupies considerable amounts of time in people’s lives and may influence creativity. However, few studies have linked mobile phone dependence (MPD) to adolescents’ domain-specific creativity (science and art). This study investigated the relationship between MPD and the scientific and artistic creativity of 2,922 adolescents (10–15 years old) by using the Test of Mobile Phone Dependence, the Middle School Students’ Everyday Creativity Questionnaire, the Rosenberg Self-Esteem Scale, and the Short Scale of Creative Self, all self-reported measures. Specifically, linear regression analysis and segmented regression analysis were conducted to explore the relationships between MPD and scientific and artistic creativity.

Probability theorem gets quantum makeover after 250 years

How likely you think something is to happen depends on what you already believe about the circumstances. That is the simple concept behind Bayes’ rule, an approach to calculating probabilities, first proposed in 1763. Now, an international team of researchers has shown how Bayes’ rule operates in the quantum world.

“I would say it is a breakthrough in ,” said Professor Valerio Scarani, Deputy Director and Principal Investigator at the Center for Quantum Technologies, and member of the team. His co-authors on the work published on 28 August 2025 in Physical Review Letters are Assistant Professor Ge Bai at the Hong Kong University of Science and Technology in China, and Professor Francesco Buscemi at Nagoya University in Japan.

“Bayes’ rule has been helping us make smarter guesses for 250 years. Now we have taught it some quantum tricks,” said Prof Buscemi.

Scientists Detected Signs of a Structure Hiding Inside Earth’s Core

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth’s history. Our history.

Research shows there are little-known chapters in that history, deep within Earth’s past. In fact, Earth’s inner core appears to have another even more inner core within it.

“Traditionally we’ve been taught the Earth has four main layers: the crust, the mantle, the outer core and the inner core,” Australian National University geophysicist Joanne Stephenson explained in 2021.

HUGE: Elon’s “Macrohard” AI — His CRAZIEST Idea Ever

Questions to inspire discussion.

Industry Disruption.

🏢 Q: How might traditional companies be affected by AI simulations? A: Traditional firms like Microsoft could see their valuation drop by 50% if undercut by AI clones, while the tech industry may experience millions of jobs vanishing, potentially leading to recessions or increased inequality.

🤖 Q: What is the potential scale of AI company simulations? A: AI-simulated companies like “Macrohard” could become real entities, operating at a fraction of the cost of traditional companies and disrupting markets 10 times faster and bigger than the internet’s impact on retail.

Regulatory Landscape.

📊 Q: How might governments respond to AI-simulated companies? A: Governments may implement regulations on AI companies to slow innovation, potentially creating monopolies that regulators would later need to break up, further disrupting markets.
