How an overlooked electrostatic force could drive the motor of the future

When we hear about moving objects with electricity, most of us imagine a “pulling force.” Positive and negative charges attract each other, drawing objects together. It is natural to think that this attractive force—known as electrostatic force—is what makes things move.

However, this force is not very strong, and it has not been suitable for driving large machines in our daily lives. For that reason, most practical motors rely on a different mechanism. For example, the motors in electric fans and electric vehicles do not use electricity directly to create motion. Instead, they use electricity to generate a magnetic field, and then use that magnetic force to rotate.

How close are we to true AI?

Understanding consciousness is the ultimate prize for creators of artificial intelligence. Nevertheless, consciousness theory will also shape how we view ourselves and our place in the world. Although AI systems can mimic human reasoning, they can only regurgitate the input data. They are sophisticated pattern recognizers and content remixers, but cannot step beyond the limitations of the input. Understanding consciousness would enable us to transition from synthetic to synthesis, unlocking unlimited potential.

Computer scientists hope that recurrent computation will somehow ‘awaken’ code to consciousness. Yet the spectacular achievements of large language and diffusion models have not moved beyond imitation. We train models on the outputs of consciousness—our language, our art, our logic—while remaining entirely ignorant of the process that produces them. An AI can write a gut-wrenching paragraph about sadness by replicating patterns, vocabulary, and syntax. But it knows nothing of grief. It can create a shadow play, yet knows nothing of the object that casts it. This imitation, while impressive, should not be mistaken for a proper understanding of consciousness. No amount of coloring can turn the shadow into a solid object.

To reverse-engineer the mind, we need a blueprint. The pressing need to advance AI is a physicalist theory of consciousness, the architecture of subjective experience itself. The Fermionic Mind Hypothesis (FMH) is such a physicalist framework. It posits that selfhood is structurally and functionally analogous to a fermion in physics. The self’s persistent core operates as an energy-regulating system, maintaining mental equilibrium through continuous thermodynamic cycles. Within this cycle, cognitive processes such as decision-making are wave-particle transitions that capture the inherent nondeterminism and contextual collapse of probabilistic mental states.

The screech of peeling sticky tape conceals a rapid train of tiny shockwaves, ultrafast imaging shows

A new experiment has uncovered the mechanism responsible for the screeching sound made by peeling sticky tape. Using a combination of ultrafast imaging and synchronized acoustic recordings, Sigurdur Thoroddsen and colleagues at King Abdullah University of Science and Technology have shown that the noise is produced by a rapid train of tiny shockwaves, released through a specialized form of stick–slip motion. The research is published in Physical Review E.

If you’ve ever used sticky tape, you’ll probably be all too familiar with the harsh sound it makes as it peels away from a surface. Yet despite decades of experimental scrutiny, physicists have yet to fully explain the origins of this intriguing acoustic effect.

Previous studies established that peeling proceeds via a “stick–slip” mechanism—a jerky motion characterized by brief, rapid accelerations interrupted by sudden stops. Similar dynamics underpin phenomena ranging from earthquakes to the squeak of basketball shoes on a polished wooden court. However, the fine details of how this process unfolds in peeling tape turned out to be more complex than they first appeared.

Major battery breakthrough paving way for EV upgrade

Chinese scientists have developed a lithium metal battery that boasts an energy density of more than 700 watt-hours per kilogram and stable performance at extremely low temperatures, marking a significant advancement in the production of high-energy batteries for electric vehicles. The research paper was published on Thursday in the science journal Nature.

Chen Jun, an academician of the Chinese Academy of Sciences and vice-president of Nankai University in Tianjin, was among the researchers who led the breakthrough. Chen said the team has replaced oxygen atoms with fluorine ones. It designed and synthesized novel fluorinated hydrocarbon solvent molecules, creating a new electrolyte system based on lithium-fluorine coordination.

Your car’s tire sensors could be used to track you

Researchers at IMDEA Networks Institute, together with European partners, have found that tire pressure sensors in modern cars can unintentionally expose drivers to tracking. Over a ten-week study, they collected signals from more than 20,000 vehicles, revealing a hidden privacy risk and highlighting the need for stronger security measures in future vehicle sensor systems.

Most modern cars are equipped with a Tire Pressure Monitoring System (TPMS), mandatory since the late 2000s in many countries for their contribution to road safety. This system uses small sensors in each wheel to monitor tire pressure and sends wireless signals to the car’s computer to alert the driver if a tire is underinflated.

However, the researchers found that these tire sensors also send a unique ID number in clear, unencrypted wireless signals, meaning that anyone nearby with a simple radio receiver can capture the signal, and recognize the same car again later. Most vehicle tracking today uses cameras that need clear visibility and line-of-sight to a car. TPMS tracking is different: tire sensors automatically send radio signals that pass through walls and vehicles, allowing small hidden wireless receivers to capture them without being seen.

The physics of sneaker squeaks: High-speed imaging shows how they arise from supersonic detachment pulses

Basketball shoes on a gym floor, bicycle brakes in need of a tune-up, or the squeal of tires are everyday examples of squeaking sounds. Such sounds have long been attributed to stick-slip friction, or a cycle of intermittent sticking and sliding between surfaces. While this framework explains many rigid-on-rigid systems such as door hinges, it does not fully capture the physics of soft-on-rigid interfaces, like shoes on a floor.

To shed light on this little-understood physical process, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), in collaboration with the University of Nottingham and the French National Center for Scientific Research, have used high-speed imaging to investigate the dynamics of soft solids sliding rapidly on rigid substrates.

In a study published in Nature, the team led by first author Adel Djellouli, a postdoctoral fellow in the lab of Katia Bertoldi, the William and Ami Kuan Danoff Professor of Applied Mechanics at SEAS, reports that squeaking emerges from a previously unseen mechanism.

Algal Swimming Patterns Change with Light Intensity

In response to changes in illumination, a swimming microorganism reverses the direction of its circular trajectory by tilting its flagella’s planes of motion.

Many microorganisms adjust their swimming trajectories in response to environmental signals such as nutrients or light. Researchers have now discovered a new mode of such behavior in a species of green algae [1]. The microbes swim in wide circles when illuminated and switch from counterclockwise (CCW) to clockwise (CW) swimming when the light intensity is above a threshold value. The researchers determined how this change is generated by the algae’s two whip-like flagella. They say that the results reveal a new navigation strategy that microorganisms can use to find optimal environments.

The single-celled green alga Chlamydomonas reinhardtii is photosynthetic and moves toward light by beating its two flagella, situated close together on its front surface, in a breaststroke pattern. In 2021, Kirsty Wan and Dario Cortese of the University of Exeter in the UK figured out the beating pattern that produces the microbe’s typical corkscrew-shaped trajectory, which follows a tight helix [2]. They showed how changing the frequency, amplitude, and synchronization of the flagellar beating allows the cell to change the overall direction of motion, perhaps to steer it toward or away from a light source and optimize the intensity of light it receives.
