The BirdNET app, a free machine-learning powered tool that can identify over 3,000 birds by sound alone, generates reliable scientific data and makes it easier for people to contribute citizen-science data on birds by simply recording sounds.

New research looks at positron scattering from rare gas atoms encapsulated in carbon 60 to investigate quantum properties that can't be tested with electrons.

Experts in AI, climate change, and public policy present a framework for understanding the complex and multifaceted relationship of AI with greenhouse gas emissions, and suggest ways to better align AI with climate change goals.

Scientists reveal their development of a new type of prosthetic using microfluidics-enabled soft robotics that promises to greatly reduce skin ulcerations and pain in patients who have had an amputation between the ankle and knee. They started with a recent device that uses pneumatic actuators and miniaturized the actuators by designing a microfluidic chip with 10 integrated pneumatic valves to control each actuator. The control box is small and light enough to be worn as part of the prosthesis.

Researchers examine some of thelatest advances in wearable electronic devices and systems being developed using electrospinning -- the fabrication of nanofibers with tunable properties from a polymer base -- and showcase the many advantages electrospun materials have over conventional bulk materials. Their high surface-to-volume ratio endows them with enhanced porosity and breathability, which is important for long-term wearability, and with the appropriate blend of polymers, they can achieve superior biocompatibility.

Computer scientists develop a method that allows humans to help complex robots build efficient solutions to 'see' their environments and carry out tasks.

Researchers have developed a virtual robotic limb system which can be operated by users' feet in a virtual environment as extra, or supernumerary, limbs. After training, users reported feeling like the virtual robotic arms had become part of their own body. This study focused on the perceptual changes of the participants, understanding of which can contribute to designing real physical robotic supernumerary limb systems that people can use naturally and freely just like our own bodies.

Scientists reveal an advanced, innovative method that they have developed and used to detect nonvisual traces of fire dating back at least 800,000 years -- one of the earliest known pieces of evidence for the use of fire. The newly developed technique may provide a push toward a more scientific, data-driven type of archaeology, but -- perhaps more importantly -- it could help us better understand the origins of the human story, our most basic traditions and our experimental and innovative nature.

People are less morally outraged when gender discrimination occurs because of an algorithm rather than direct human involvement, according to new research.

Fine-tuning the thermal conductivity of amorphous silicon used in technologies such as solar cells and image sensors should become much easier thanks to the computational topology and machine-learning-assisted discovery of the relationship between nano-scale structures and physical properties.
