A biohybrid hand which can move objects and do a scissor gesture has been created. The researchers used thin strings of lab-grown muscle tissue bundled into sushilike rolls to give the fingers enough strength to contract. These multiple muscle tissue actuators (MuMuTAs), created by the researchers, are a major development towards building larger biohybrid limbs. While currently limited to the lab environment, MuMuTAs have the potential to advance future biohybrid prosthetics, aid drug testing on muscle tissue and broaden the potential of biohybrid robotics to mimic real-life forms.

Researchers have achieved a breakthrough in wearable health technology by developing a novel self-healing electronic skin (E-Skin) that repairs itself in seconds after damage. This could potentially transform the landscape of personal health monitoring.

A new study has revealed the clearest-ever picture of the surface chemistry of worm species that provides groundbreaking insights into how animals interact with their environment and each other. These discoveries could pave the way for strategies to deepen our understanding of evolutionary adaptations, refine behavioural research, and ultimately overcome parasitic infections.

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light in ways that appear to defy the laws of Nature. Negative refraction -- a phenomenon where light bends in the opposite direction to its usual behavior -- has captivated researchers for its potential to revolutionize optics, enabling transformative technologies such as superlenses and cloaking devices. Now, carefully arranged arrays of atoms have brought these possibilities a step closer, achieving negative refraction without the need for artificially manufactured metamaterials.

Using genes borrowed from bacteria, researchers have demonstrated fish and flies can be engineered to break down methylmercury and remove it from their bodies as a less harmful gas, offering new ways to tackle one of the world's most dangerous pollutants.

Scientists have used holographic projections to bring unprecedented resolution to a light-based 3D printing technique. The method allows the fabrication of millimeter-scale objects within seconds using significantly less energy than previous approaches.

Researchers have developed a novel experimental platform to measure the electric fields of light trapped between two mirrors with a sub-cycle precision. These electro-optic Fabry-Perot resonators will allow for precise control and observation of light-matter interactions, particularly in the terahertz (THz) spectral range. By developing a tunable hybrid-cavity design, and measuring and modeling its complex sets of allowed modes, the physicists can switch between nodes and maxima of the light waves exactly at the location of interest. The study opens new avenues for exploring quantum electrodynamics and ultrafast control of material properties.

Scientists have just detected a neutrino that is thirty times more energetic than any previously detected anywhere in the world. This exceptional discovery opens up new perspectives for understanding extreme energy phenomena in the Universe and the origin of cosmic rays.

Researchers developed a method to recycle all parts of a solar cell repeatedly without environmentally hazardous solvents. The recycled solar cell has the same efficiency as the original one. The solar cell is made of perovskite and the main solvent is water.

New research could transform how broken bones are treated, with the development of a special zinc-based dissolvable material that could replace the metal plates and screws typically used to hold fractured bones together.

Biomedical engineers have demonstrated a new synthetic approach that turbocharges bacteria into producing more of a specific protein, even proteins that would normally destroy them, such as antibiotics. The technique could be a boon to industries that use bacteria to produce a wide range of products such as pharmaceuticals, industrial chemicals and biofuels.

Scientists have developed new light-sensitive chemicals that can radically improve the treatment of aggressive cancers with minimal side effects. In mouse tests, the new therapy completely eradicated metastatic breast cancer tumors.

Combustion engines, the engines in gas-powered cars, only use a quarter of the fuel's potential energy while the rest is lost as heat through exhaust. Now, a study demonstrates how to convert exhaust heat into electricity. The researchers present a prototype thermoelectric generator system that could reduce fuel consumption and carbon dioxide emissions -- an opportunity for improving sustainable energy initiatives in a rapidly changing world.

A new study sheds light on how the extreme miniaturization of thin films affects the behavior of relaxor ferroelectrics -- materials with noteworthy energy-conversion properties used in sensors, actuators and nanoelectronics.
