Birds fly more efficiently by folding their wings during the upstroke, according to a recent study. The results could mean that wing-folding is the next step in increasing the propulsive and aerodynamic efficiency of flapping drones.

What is the best way to teach a robot? Sometimes it may simply be to speak to it clearly. Researchers found that human-language descriptions of tools can accelerate the learning of a simulated robotic arm lifting and using a variety of tools.

As the supersonic solar wind surges towards Earth, its interaction with our planet's magnetic field creates a shock to deflect its flow, and a foreshock filled with electromagnetic waves. How these waves can propagate to the other side of the shock has long remained a mystery.

Experimental data is often not only highly dimensional, but also noisy and full of artefacts. This makes it difficult to interpret the data. Now a team has designed software that uses self-learning neural networks to compress the data in a smart way and reconstruct a low-noise version in the next step. This enables it to recognize correlations that would otherwise not be discernible. The software has now been successfully used in photon diagnostics at the FLASH free electron laser at DESY. But it is suitable for very different applications in science.

Researchers have developed a method that allows a flapping-wing robot to land autonomously on a horizontal perch using a claw-like mechanism. The innovation could significantly expand the scope of robot-assisted tasks.

Enhancing the virtual experience with the touch sensation has become a hot topic, but today's haptic devices remain typically bulky and tangled with wires. Researchers have now developed an advanced wireless haptic interface system, called WeTac, worn on the hand, which has soft, ultrathin soft features, and collects personalized tactile sensation data to provide a vivid touch experience in the metaverse.

A new gelatinous robot that crawls, powered by nothing more than temperature change and clever design, brings 'a kind of intelligence' to the field of soft robotics.

Structures made out of building blocks can shift their shape and autonomously self-organize to a new configuration. The physicists revealed this mechanism which may be used to actively manipulate molecular organization. A seed of the novel desired configuration is sufficient to trigger reorganization. This principle can be applied on to biological building blocks which are constantly recycled to form new structures in living systems.

Self-driving cars need to implement efficient, effective, and accurate detection systems to provide a safe and reliable experience to its users. To this end, an international research team has now developed an end-to-end neural network that, in conjunction with the Internet-of-Things technology, detects object with high accuracy (> 96%) in both 2D and 3D. The new method outperforms the current state-of-the-art methods and the way to new 2D and 3D detection systems for autonomous vehicles.

As low Earth orbit becomes more cluttered, it becomes increasingly necessary to use middle Earth orbits, and radiation-tolerant cell designs will be needed. Making photovoltaics thinner should increase their longevity because the charge carriers have less far to go during their shortened lifetimes. Scientists propose a radiation-tolerant photovoltaic cell design that features an ultrathin layer of light-absorbing material. Compared to thicker cells, nearly 3.5 times less cover glass is needed for the ultra-thin cells to deliver the same amount of power after 20 years of operation.
