Since the first fiber optic cables rolled out in the 1970s, they've become a major part of everything from medical devices to high-speed internet and cable TV. But as it turns out, one group of marine mollusks was way ahead of us. A new study reveals that clams called heart cockles have unique structures in their shells that act like fiber optic cables to convey specific wavelengths of light into the bivalves' tissues.

Researchers have demonstrated a new technique for self-assembling electronic devices. The proof-of-concept work was used to create diodes and transistors, and paves the way for self-assembling more complex electronic devices without relying on existing computer chip manufacturing techniques.

A theoretical study suggests that small black holes born in the early universe may have left behind hollow planetoids and microscopic tunnels, and that we should start looking within rocks and old buildings for them. The research proposes thinking both big and small to confirm the existence of primordial black holes, suggesting that their signatures could range from very large -- hollow planetoids in space -- to minute -- microscopic tunnels in everyday materials found on Earth, like rocks, metal and glass.

Scientists have a new way to use data from high-energy particle smashups to peer inside protons. Their approach uses quantum information science to map out how particle tracks streaming from electron-proton collisions are influenced by quantum entanglement inside the proton. The results reveal that quarks and gluons, the fundamental building blocks that make up a proton's structure, are subject to so-called quantum entanglement.

An international team has tracked at BESSY II how heavy molecules -- in this case bromochloromethane -- disintegrate into smaller fragments when they absorb X-ray light. Using a newly developed analytical method, they were able to visualize the ultrafast dynamics of this process. In this process, the X-ray photons trigger a 'molecular catapult effect': light atomic groups are ejected first, similar to projectiles fired from a catapult, while the heavier atoms -- bromine and chlorine -- separate more slowly.

Scientists have invented a liquid ink that doctors can print onto a patient's scalp to measure brain activity. The technology offers a promising alternative to the cumbersome process currently used for monitoring brainwaves and diagnosing neurological conditions. It also has the potential to enhance non-invasive brain-computer interface applications.

Where do you see patterns in chaos? It has now been demonstrated in the incredibly tiny quantum realm. Researchers detail an experiment that confirms a theory first put forth 40 years ago stating that electrons confined in quantum space would move along common paths rather than producing a chaotic jumble of trajectories.

Researchers developed a fully integrated photonic processor that can perform all the key computations of a deep neural network on a photonic chip, using light. This advance could improve the speed and energy-efficiency of running intensive deep learning models for demanding applications like lidar, astronomical research, and navigation.

Researchers have created the smallest walking robot yet. Its mission: to be tiny enough to interact with waves of visible light and still move independently, so that it can maneuver to specific locations -- in a tissue sample, for instance -- to take images and measure forces at the scale of some of the body's smallest structures.

The increased use of a chemical compound to replace TNT in explosive devices has a damaging and long lasting effect on plants, new research has shown.

Researchers' new polymer strategy shifts a centuries-old engineering paradigm with a molecular design that doesn't sacrifice stretchability for stiffness.

Using 'DNA origami' scientists have built innovative nanostructures that pave the way for advanced robotics that can deliver targeted drugs -- plus they made a tiny map of Australia and mini dinosaurs.

A tiny, four-fingered 'hand' folded from a single piece of DNA can pick up the virus that causes COVID-19 for highly sensitive rapid detection and can even block viral particles from entering cells to infect them, researchers report. Dubbed the NanoGripper, the nanorobotic hand also could be programmed to interact with other viruses or to recognize cell surface markers for targeted drug delivery, such as for cancer treatment.

A research team has found a way to make more efficient the desorption of water-adsorption polymers used in atmospheric water harvesting and desiccant air conditioning.

Researchers have investigated how cationic polymers organize on a molecular level when transporting RNA drugs.

A team of physics educators is focusing on a new approach to teaching quantum physics in schools. Traditional classroom teaching has tended to focus on presenting the history of the origins of quantum physics, which often poses problems for learners. Using the quantum measurement process as an example, the researchers have now published their first empirical findings on learning quantum physics -- based on two-state systems.

Chemists unravel how bicarbonate can protect cells from oxidative stress in a study that challenges how cell damage has been studied for decades.

A team of researchers has developed an innovative imaging platform that promises to improve our understanding of cellular structures at the nanoscale. This platform, called soTILT3D for single-objective tilted light sheet with 3D point spread functions (PSFs), offers significant advancements in super-resolution microscopy, enabling fast and precise 3D imaging of multiple cellular structures while the extracellular environment can be controlled and flexibly adjusted.

Researchers propose a new method to generate meteorological data that takes into account the interdependence of meteorological factors, such as temperature, humidity, and solar radiation.

This unobtrusive, leaf-mounted sensor saves time and improves productivity by remotely monitoring the health of plants in real-time.
