Male lava lizards are sensitive to the timing of their opponents’ responses during contest displays, with quicker responses being perceived as more aggressive, a study in Behavioural Ecology and Sociobiology suggests. To avoid injury from male-to-male contests, some animal species display behaviours such as color changes or sequences of movements that showcase body size and … Read more
Imagine swarms of robotic insects moving around us as they perform various tasks. It might sound like science fiction, but it’s actually more plausible than you might think. Researchers at EPFL’s School of Engineering have developed a soft robotic insect, propelled at 3 cm per second by artificial muscles. The team developed two versions of … Read more
Artificial intelligence (AI) technology developed by the RIKEN Center for Advanced Intelligence Project (AIP) in Japan has successfully found features in pathology images from human cancer patients, without annotation, that could be understood by human doctors. Further, the AI identified features relevant to cancer prognosis that were not previously noted by pathologists, leading to a … Read more
Researchers have demonstrated how kirigami-inspired techniques allow them to design thin sheets of material that automatically reconfigure into new two-dimensional (2D) shapes and three-dimensional (3D) structures in response to environmental stimuli. The researchers created a variety of robotic devices as a proof of concept for the approach. “This is the first case that we know … Read more
Conditioning is a method made famous by Ivan Pavlov’s experiments with dogs. Pavlov trained a dog by ringing a bell every time the dog was fed. The dog learned to associate the bell with food, and then drooled when it heard the bell ring, even if it didn’t see anything to eat. In an earlier … Read more
Scientists have added a crucial tool to the atomic-scale manufacturing toolkit with major implications for today’s data driven–carbon intensive–world, according to new research from the University of Alberta in Canada. “Computers today are contributing one gigatonne of carbon emissions to the atmosphere, and we can eliminate that by enhancing the most power-hungry parts of conventional … Read more
At a time when ocean noise is receiving increased global attention, researchers at Oregon State University and NOAA have developed an effective method to use an underwater robotic glider to measure sound levels over broad areas of the sea. “Healthy marine ecosystems need to have noise levels within particular ranges,” said Joe Haxel, an assistant … Read more
Researchers at the Paul Scherrer Institute PSI and ETH Zurich have developed a micromachine that can perform different actions. First nanomagnets in the components of the microrobots are magnetically programmed and then the various movements are controlled by magnetic fields. Such machines, which are only a few tens of micrometres across, could be used, for … Read more
Thinking about sex and gender would help scientists improve their research, a new article published today argues. Writing in a special 150th anniversary edition of Nature, five experts say these factors are too often ignored. They say incorporating sex (the biological attribute distinguishing females, males or intersex/hermaphrodite individuals) and gender (psychological, social and cultural factors affecting … Read more
The sight of a RoboBee careening towards a wall or crashing into a glass box may have once triggered panic in the researchers in the Harvard Microrobotics Laboratory at the Harvard John A. Paulson School of Engineering and Applied Science (SEAS), but no more. Researchers at SEAS and the Wyss Institute for Biologically Inspired Engineering … Read more
