Scientists develop 'smart paint' that reflects 97% of sunlight and could reduce AC use during heatwaves
As heatwaves become more frequent and intense around the world, scientists are exploring new ways to keep buildings cool without increasing energy consumption. Researchers at the University of Sydney, working with startup Dewpoint Innovations, have developed a nano-engineered coating that reflects up to 97% of sunlight and stays significantly cooler than conventional surfaces. The experimental "smart paint" is designed to reduce heat absorption, lower indoor temperatures and potentially...
Plants could be used to grow medicines in space, study shows
Plants could be used to grow medicines in space, study shows Lisa Lock Scientific Editor Robert Egan Associate Editor Astronauts on long space missions may one day use plants to produce fresh stocks of medicines on demand, thanks to new research by engineers at the University of California San Diego. The team developed a simple method to grow and repeatedly harvest pharmaceuticals from plants under space-like conditions, without destroying the plants or generating large amounts of waste. The...
Desi jugaads during heatwaves: India’s battle against 45°C temperatures
India is learning to live with a hotter future. From Delhi to Mumbai, temperatures are regularly crossing 45 degrees Celsius, heatwaves are lasting longer and cities are becoming giant heat traps due to rapid urbanisation and the growing urban heat island effect. But if there is one thing Indians are famous for, it is finding a jugaad for every problem.
MuJoCo-Drones-Gym: A GPU-Accelerated Multi-Drone Simulator for Control and Reinforcement Learning
Announce Type: new Abstract: Robotic simulators are a cornerstone of modern research in aerial robotics, serving both as a vehicle for the development of new control algorithms and as the data source for training reinforcement learning (RL) policies. Yet, existing quadcopter learning environments often face a trade-off between physical fidelity, multi-agent support, and the throughput required by modern deep RL pipelines. In this paper, we present MuJoCo-Drones-Gym, an open-source...
Van der Waals forces can play unexpected role in thin film properties
Van der Waals forces can play unexpected role in thin film properties Lisa Lock Scientific Editor Andrew Zinin Lead Editor Researchers have demonstrated the ability to use van der Waals forces to tune the physical and electronic properties of ferroelectric thin films. The work opens the door to new techniques for engineering materials for use in smaller, more energy efficient electronic devices. "Epitaxy is when you deposit a crystalline layer of material on top of another crystalline layer...
Medicinal plants yield carbon nanoparticles that glow red and flag toxic metals
Medicinal plants yield carbon nanoparticles that glow red and flag toxic metals Stephanie Baum Scientific Editor Robert Egan Associate Editor What do iron, lead and nickel have in common? These heavy metals are an indispensable part of many industries. However, they also share a dark reality: They are serious environmental and public health threats.
Nvidia Cosmos 3
Physical AI systems must understand the real world before they can act within it. Robots, autonomous vehicles, and smart spaces need to understand what’s happening in their world, predict what’s likely to happen next, and generate actions for specific environments, embodiments, and tasks. NVIDIA Cosmos 3 is a frontier foundation model for physical AI that combines physical reasoning, world generation, and action generation within a single open model.
Light-induced quantum friction of carbon nanotubes in water
Abstract Friction slows down moving objects at both macroscopic and microscopic scales1. At the electronic level, quantum friction describes direct transfer of momentum between a liquid and the electrons of a solid2. Owing to its microscopic nature, this phenomenon remains experimentally challenging to capture3.
Towards Realistic 3D Sonar Simulation
arXiv:2606.06130v1 Announce Type: new Abstract: As underwater robotics research increasingly addresses complex 3D perception and autonomous navigation, the fidelity of sonar simulation has become a key factor in algorithm development. Current simulation frameworks typically rely on geometry-driven rendering, approximating 3D sonar as an underwater equivalent to LiDAR, which fails to account for fundamental acoustic phenomena such as refraction, multi-path interference, and phase-dependent...
