In nature, cockroaches can survive underwater for up to 30 minutes. Now, a robotic cockroach can do even better. Harvard’s Ambulatory Microrobot, known as HAMR, can walk on land, swim on the surface of water, and walk underwater for as long as necessary, opening up new environments for this little bot to explore. This next

Microelectrodes can be used for direct measurement of electrical signals in the brain or heart. These applications require soft materials, however. With existing methods, attaching electrodes to such materials poses significant challenges. A team at the Technical University of Munich (TUM) has now succeeded in printing electrodes directly onto several soft substrates. Researchers from TUM

An international team of scientists from Eindhoven University of Technology, University of Texas at Austin, and University of Derby, has developed a revolutionary method that quadratically accelerates artificial intelligence (AI) training algorithms. This gives full AI capability to inexpensive computers, and would make it possible in one to two years for supercomputers to utilize Artificial

Waste oil from orange, tea tree and eucalyptus essential oil production mixed with diesel provides a sweet-smelling biofuel blend with comparable performance to diesel-only fuel. QUT Ph.D. researcher Ashrafur Rahman tested each of the waste oils for performance and emissions as a 10 per cent oil/90per cent diesel blend in a 6-cylinder, 5.9l diesel engine.

Scientists at Tokyo Institute of Technology have designed and fabricated a tiny, but incredibly fast, reliable, and accurate 28-GHz transceiver meant for stable high-speed 5G communications. The fabricated transceiver trumps previous designs in various regards by taking a new approach for beam steering. The importance of wireless communications is evident in modern societies, and thus,

A new paper in the Proceedings of the National Academy of Sciences (PNAS) reports how a cutting-edge artificial intelligence technique called deep learning can automatically identify, count and describe animals in their natural habitats. Photographs that are automatically collected by motion-sensor cameras can then be automatically described by deep neural networks. The result is a

A team of academic researchers is seeking clarity on predictive plug-in electric vehicle (PEV) models. An examination of more than three dozen studies is providing some meaningful insights. “The value of the models is not in their predictive power, but in connecting ‘important’ factors in a way that enables us to construct some possible future

The world is a big place, but it’s gotten smaller with the advent of technologies that put people from across the globe in the palm of one’s hand. And as the world has shrunk, it has also demanded that things happen ever faster—including the time it takes to charge an electronic device. A cross-campus collaboration

An innovative, eel-like robot developed by engineers and marine biologists at the University of California can swim silently in salt water without an electric motor. Instead, the robot uses artificial muscles filled with water to propel itself. The foot-long robot, which is connected to an electronics board that remains on the surface, is also virtually

In a groundbreaking new study, researchers at the University of Minnesota used a customized, low-cost 3D printer to print electronics on a real hand for the first time. The technology could be used by soldiers on the battlefield to print temporary sensors on their bodies to detect chemical or biological agents or solar cells to
