| Quantum sensor can detect electromagnetic signals of any frequency Posted: 21 Jun 2022 03:44 PM PDT Researchers developed a method to enable quantum sensors to detect any arbitrary frequency, with no loss of their ability to measure nanometer-scale features. Quantum sensors detect the most minute variations in magnetic or electrical fields, but until now they have only been capable of detecting a few specific frequencies, limiting their usefulness. |
| How the brain interprets motion while in motion Posted: 21 Jun 2022 12:51 PM PDT New research provides insights into a neural mechanism involved in how the brain interprets sensory information. The research may have applications for treating brain disorders and designing artificial intelligence. |
| Robotic lightning bugs take flight Posted: 21 Jun 2022 11:18 AM PDT Inspired by fireflies, researchers created soft actuators that can emit light in different colors or patterns. These artificial muscles, which control the wings of featherweight flying robots, light up while the robot is in flight, which provides a low-cost way to track the robots and also could enable them to communicate. |
| Robots turn racist and sexist with flawed AI, study finds Posted: 21 Jun 2022 11:17 AM PDT A robot operating with a popular Internet-based artificial intelligence system consistently gravitates to men over women, white people over people of color, and jumps to conclusions about peoples' jobs after a glance at their face. The work is believed to be the first to show that robots loaded with an accepted and widely-used model operate with significant gender and racial biases. |
| SeqScreen can reveal 'concerning' DNA Posted: 21 Jun 2022 11:17 AM PDT Computer scientists have developed a program to screen short DNA sequences, whether synthetic or natural, to determine their toxicity. |
| Magnetic superstructures resonate with global 6G developers Posted: 21 Jun 2022 06:14 AM PDT Scientists have detected collective resonance at remarkably high and broad frequency bands. In a magnetic superstructure called a chiral spin soliton lattice (CSL), they found that resonance could occur at such frequencies with small changes in magnetic field strength. The findings suggest CSL-hosting chiral helimagnets as promising materials for future communication technologies. |
| Posted: 20 Jun 2022 07:08 AM PDT Species have intrinsic value, but also provide ecosystem services of major economic value, for example, bees that pollinate our crops. However, as such values are hard to translate into figures, currently, they remain easy to dismiss altogether. In a new study, a research team conceptualizes a species stock market for unified valuation of all species. By using digitized information from museums, occurrence data, and DNA sequence databases, this market quantifies our knowledge of each species from scientific, societal, and economic points of view. |
