Engineers have developed modular nanoparticles that can be easily customized to target different biological entities such as tumors, viruses or toxins. The surface of the nanoparticles is engineered to host any biological molecules of choice, making it possible to tailor the nanoparticles for a wide array of applications, ranging from targeted drug delivery to neutralizing biological agents.

Smart, stretchable and highly sensitive, a new soft sensor opens the door to a wide range of applications in robotics and prosthetics. When applied to the surface of a prosthetic arm or a robotic limb, the sensor skin provides touch sensitivity and dexterity, enabling tasks that can be difficult for machines such as picking up a piece of soft fruit. The sensor is also soft to the touch, like human skin, which helps make human interactions safer and more lifelike.

Researchers introduce a pioneering breakthrough in the world of nanomotors -- the DNA origami nanoturbine. This nanoscale device could represent a paradigm shift, harnessing power from ion gradients or electrical potential across a solid-state nanopore to drive the turbine into mechanical rotations. The core of this pioneering discovery is the design, construction, and driven motion of a 'DNA origami' turbine, which features three chiral blades, all within a minuscule 25-nanometer frame, operating in a solid-state nanopore. By ingeniously designing two chiral turbines, researchers now have the capability to dictate the direction of rotation, clockwise or anticlockwise.

Researchers have developed a system that uses atomic vacancies in silicon carbide to measure the stability and quality of acoustic resonators. What's more, these vacancies could also be used for acoustically-controlled quantum information processing, providing a new way to manipulate quantum states embedded in this commonly-used material.

Dispersions of polymer particles in a liquid phase (latexes) have many important applications in coatings technology, medical imaging, and cell biology. A team of researchers has now developed a method to produce stable polystyrene dispersions with unprecedentedly large, and uniform, particle sizes. Narrow size distributions are essential in many advanced technologies, but were previously difficult to produce photochemically.

The perception of persistent thermal sensations, such as changes in temperature, tends to gradually diminish in intensity as our bodies become accustomed to the temperature. This phenomenon leads to a shift in our perception of temperature when transitioning between different scenes in a virtual environment. Researchers have now developed a technology to generate a virtual cold sensation via a non-contact method without physically altering the skin temperature.

Physicists have now shown that, depending on the extent to which the propulsion speed of active particles is dependent on their orientation, clusters in different shapes arise in many-particle systems. This might be a possible key to the realization of programmable matter.

Particle accelerators are crucial tools in a wide variety of areas in industry, research and the medical sector. The space these machines require ranges from a few square meters to large research centers. Using lasers to accelerate electrons within a photonic nanostructure constitutes a microscopic alternative with the potential of generating significantly lower costs and making devices considerably less bulky. Until now, no substantial energy gains were demonstrated. In other words, it has not been shown that electrons really have increased in speed significantly. Two teams of laser physicists have just succeeded in demonstrating a nanophotonic electron accelerator.

Attempts to break the diffraction limit with 'super lenses' have all hit the hurdle of extreme visual losses. Now physicists have shown a new pathway to achieve superlensing with minimal losses, breaking through the diffraction limit by a factor of nearly four times. The key to their success was to remove the super lens altogether.

Engineers have developed an experimental vaccine that could prevent the spread of metastatic cancers to the lungs. Its success lies in targeting a protein known to play a central role in cancer growth and spread, rather than targeting the primary tumor itself.
