A fresh study suggests that the way a person’s pupils change while they concentrate hints at how well that mental scratchpad is working.

Working memory does more than hold stray reminders; it stitches together phone digits until they are dialed, keeps track of a spoken sentence until the meaning lands, and buffers half-finished ideas during problem-solving.

Unlike long-term memory, it works on a tight clock measured in seconds. Because the capacity is finite – typically three to seven items at once – small differences in efficiency can ripple through reading, mathematics, and decision-making.

Ultra-thin display technology shows dozens of images hidden in a single screen https://lifeboat.com/blog/2025/05/ultra-thin-display-technology-shows-dozens-of-images-hidden-in-a-single-screen https://lifeboat.com/blog/2025/05/ultra-thin-display-technology-shows-dozens-of-images-hidden-in-a-single-screen#respond Tue, 27 May 2025 18:12:46 +0000 https://lifeboat.com/blog/2025/05/ultra-thin-display-technology-shows-dozens-of-images-hidden-in-a-single-screen

From smartphones and TVs to credit cards, technologies that manipulate light are deeply embedded in our daily lives, many of which are based on holography. However, conventional holographic technologies have faced limitations, particularly in displaying multiple images on a single screen and in maintaining high-resolution image quality.

Recently, a research team led by Professor Junsuk Rho at POSTECH (Pohang University of Science and Technology) has developed a groundbreaking metasurface technology that can display up to 36 on a surface thinner than a . This research has been published in Advanced Science.

This achievement is driven by a special nanostructure known as a metasurface. Hundreds of times thinner than a human hair, the metasurface is capable of precisely manipulating light as it passes through. The team fabricated nanometer-scale pillars using silicon nitride, a material known for its robustness and excellent optical transparency. These pillars, referred to as meta-atoms, allow for fine control of light on the metasurface.

What if everything around you — your phone, your chair, even the stars — has some form of consciousness? In our new video, we dive into mind-bending theories from scientists and philosophers that challenge how we see reality itself. This isn’t science fiction — it’s a serious debate shaking up physics, philosophy, and neuroscience. Could the entire universe be aware? And what does that mean for us? 🌀 Tap in and prepare to question everything you thought you knew about existence.

Quantum heat circuits: A diode framework for quantum thermal transistors https://lifeboat.com/blog/2025/05/quantum-heat-circuits-a-diode-framework-for-quantum-thermal-transistors https://lifeboat.com/blog/2025/05/quantum-heat-circuits-a-diode-framework-for-quantum-thermal-transistors#respond Wed, 21 May 2025 10:21:00 +0000 https://lifeboat.com/blog/2025/05/quantum-heat-circuits-a-diode-framework-for-quantum-thermal-transistors

Transistors are the fundamental building blocks behind today’s electronic revolution, powering everything from smartphones to powerful servers by controlling the flow of electrical currents. But imagine a parallel world, where we could apply the same level of control and sophistication—not to electricity, but to heat.

This is precisely the frontier being explored through quantum thermal , devices designed to replicate electronic transistor functionality at the quantum scale, but for heat.

The rapidly growing field of quantum thermodynamics has been making impressive strides, exploring how heat and energy behave when quantum mechanical effects dominate. Innovations such as quantum thermal diodes, capable of directing in a specific direction, and quantum thermal transistors, which amplify heat flows similarly to how electronic transistors amplify electric signals, are groundbreaking examples of this progress.

Synchron BCI Home https://lifeboat.com/blog/2025/05/synchron-bci-home https://lifeboat.com/blog/2025/05/synchron-bci-home#comments Sun, 18 May 2025 18:15:00 +0000 https://lifeboat.com/blog/2025/05/synchron-bci-home

The Synchron BCI system is designed to measure electrical brain activity corresponding with a person’s intention to move a body part, such as their arm, regardless of the body’s ability to move. This signal is then converted into a digital action, such as a click or scroll, on a smartphone, tablet, or computer.

Coming to a Brain Near You: A Tiny Computer https://lifeboat.com/blog/2025/05/coming-to-a-brain-near-you-a-tiny-computer https://lifeboat.com/blog/2025/05/coming-to-a-brain-near-you-a-tiny-computer#respond Sat, 17 May 2025 22:10:43 +0000 https://lifeboat.com/blog/2025/05/coming-to-a-brain-near-you-a-tiny-computer

Brain-computer interfaces are already letting people with paralysis control computers and communicate their needs, and will soon enable them to manipulate prosthetic limbs without moving a muscle.

The year ahead is pivotal for the companies behind this technology.

Fewer than 100 people to date have had brain-computer interfaces permanently installed. In the next 12 months, that number will more than double, provided the companies with new FDA experimental-use approval meet their goals in clinical trials. Apple this week announced its intention to allow these implants to control iPhones and other products.

Light is the science of the future: The Africans using it to solve local challenges https://lifeboat.com/blog/2025/05/light-is-the-science-of-the-future-the-africans-using-it-to-solve-local-challenges https://lifeboat.com/blog/2025/05/light-is-the-science-of-the-future-the-africans-using-it-to-solve-local-challenges#respond Thu, 15 May 2025 06:20:54 +0000 https://lifeboat.com/blog/2025/05/light-is-the-science-of-the-future-the-africans-using-it-to-solve-local-challenges

Light is all around us, essential for one of our primary senses (sight) as well as life on Earth itself. It underpins many technologies that affect our daily lives, including energy harvesting with solar cells, light-emitting-diode (LED) displays and telecommunications through fiber optic networks.

The smartphone is a great example of the power of light. Inside the box, its electronic functionality works because of quantum mechanics. The front screen is an entirely photonic device: liquid crystals controlling light. The back too: white light-emitting diodes for a flash, and lenses to capture images.

We use the word photonics, and sometimes optics, to capture the harnessing of light for and technologies. Their importance in is celebrated every year on 16 May with the International Day of Light.

Interlocked electrodes push silicon battery lifespan beyond limits https://lifeboat.com/blog/2025/05/interlocked-electrodes-push-silicon-battery-lifespan-beyond-limits https://lifeboat.com/blog/2025/05/interlocked-electrodes-push-silicon-battery-lifespan-beyond-limits#respond Wed, 14 May 2025 23:10:28 +0000 https://lifeboat.com/blog/2025/05/interlocked-electrodes-push-silicon-battery-lifespan-beyond-limits

As demand surges for batteries that store more energy and last longer—powering electric vehicles, drones, and energy storage systems—a team of South Korean researchers has introduced an approach to overcome a major limitation of conventional lithium-ion batteries (LIBs): unstable interfaces between electrodes and electrolytes.

Most of today’s consumer electronics—such as smartphones and laptops—rely on graphite-based batteries. While graphite offers long-term stability, it falls short in .

Silicon, by contrast, can store nearly 10 times more lithium ions, making it a promising next-generation anode material. However, silicon’s main drawback is its dramatic volume expansion and contraction during charge and discharge, swelling up to three times its original size.
