Researchers use artificial intelligence to ID mosquitoes

Thu, 12/17/2020 - 20:52
Rapid and accurate identification of mosquitoes that transmit human pathogens such as malaria is an essential part of mosquito-borne disease surveillance. Now, researchers have shown the effectiveness of an artificial intelligence system -- known as a Convoluted Neural Network -- to classify mosquito sex, genus, species and strain.

Artificial intelligence classifies supernova explosions with unprecedented accuracy

Thu, 12/17/2020 - 19:53
Scientists have trained machine learning software to classify supernovae without the traditional use of spectra. The project -- the first to use real supernovae data to inform its artificial intelligence -- is 82% accurate. Currently, scientists take spectra of 10-percent of the ~10,000 supernovae discovered each year. When the Rubin Observatory goes online, only 0.1-percent of the expected supernovae discoveries will be further studied without the new software.

Teaching artificial intelligence to adapt

Wed, 12/16/2020 - 21:52
Getting computers to 'think' like humans is the holy grail of artificial intelligence, but human brains turn out to be tough acts to follow. Now, researchers have used a computational model of brain activity to simulate this process more accurately than ever before. The new model mimics how the brain's prefrontal cortex uses a phenomenon known as 'gating' to control the flow of information between different areas of neurons.

AI model shows promise to generate faster, more accurate weather forecasts

Tue, 12/15/2020 - 20:22
A model based solely on the past 40 years of weather events uses 7,000 times less computer power than today's weather forecasting tools. An A.I.-powered model could someday provide more accurate forecasts for rain, snow and other weather events.

Engineers develop soft robotic gripper

Tue, 12/15/2020 - 19:12
Scientists often look to nature for cues when designing robots - some robots mimic human hands while others simulate the actions of octopus arms or inchworms. Now, researchers have designed a new soft robotic gripper that draws inspiration from an unusual source: pole beans.

'Chaotic' way to create insectlike gaits for robots

Tue, 12/15/2020 - 17:20
Researchers are embracing chaos and nonlinear physics to create insectlike gaits for tiny robots -- complete with a locomotion controller to provide a brain-machine interface. Biology and physics are permeated by universal phenomena fundamentally grounded in nonlinear physics, and it inspired the researchers' work. The group now describes using a system of three nonlinear differential equations as a building block for central pattern generators to control the gait of a robotic insect.

Wireless, ultra-thin and battery-free strain sensors that are 10 times more sensitive

Tue, 12/15/2020 - 15:59
A research team has developed a new range of strain sensors that are 10 times more sensitive when measuring minute movements. These sensors are ultra-thin, battery-free and can transmit data wirelessly, making them attractive for a wide range of applications.

Researchers uncover blind spots at the intersection of AI and neuroscience

Tue, 12/15/2020 - 14:20
Is it possible to read a person's mind by analyzing the electric signals from the brain? The answer may be much more complex than most people think. In a new article, researchers say a prominent dataset used to try to answer this question is confounded, and therefore many eye-popping findings that were based on this dataset and received high-profile recognition are false after all.

Mon, 12/14/2020 - 22:43
Gait training using robotic exoskeletons improved motor function in adolescents and young adults with acquired brain injury.

Challenges of fusing robotics and neuroscience

Fri, 12/11/2020 - 17:54
Combining neuroscience and robotic research has gained impressive results in the rehabilitation of paraplegic patients. A research team was able to show that exoskeleton training not only helped patients to walk, but also stimulated their healing process. With these findings in mind, a professor wants to take the fusion of robotics and neuroscience to the next level.

'The robot made me do it': Robots encourage risk-taking behavior in people

Fri, 12/11/2020 - 16:06
New research has shown robots can encourage humans to take greater risks in a simulated gambling scenario than they would if there was nothing to influence their behaviors. Increasing our understanding of whether robots can affect risk-taking could have clear ethical, practical and policy implications, which this study set out to explore.

Artificial intelligence helps scientists develop new general models in ecology

Fri, 12/11/2020 - 16:06
The automation of scientific discoveries is here to stay. Among others, a machine-human cooperation found a hitherto unknown general model explaining the relation between the area and age of an island and the number of species it hosts.
