Owls are fascinating creatures that can fly silently through some of the quietest places. Their wings make no noise while flying, enabling them to accurately locate their prey using their exceptional hearing ability while remaining undetected. This unique ability depends on many factors and has long been a hot research subject.

Web 3.0 is an internet paradigm that is based around blockchain technology, an advanced database mechanism. Compared to Web 2.0, the current internet paradigm, Web 3.0 provides some added advantages, such as transparency and decentralized control structures. This is because Web 3.0 is designed to work over trustless and permissionless networks.

En la búsqueda por lograr un impacto climático neto neutral, muchas empresas buscan comprar energía adicional de fuentes de energía limpia en un intento de eliminar las emisiones que de otro modo se generarían al operar en la red actual, rica en combustibles fósiles.

A magnitude 7.1 earthquake struck a sparsely populated part of China's western Xinjiang region, injuring six people and damaging or collapsing more than 120 homes.

Florida manatees have been experiencing an unusual mortality event in recent years, many dying from starvation, disease and watercraft incidents.

Researchers at Linköping University, Sweden, have developed a new, more environmentally friendly way to create conductive inks for use in organic electronics such as solar cells, artificial neurons, and soft sensors. The findings, published in the journal Nature Communications, pave the way for future sustainable technology.

A group of researchers from the Technion Faculty of Materials Science and Engineering has presented a new technology for producing green hydrogen using renewable energy. Their breakthrough was recently published in Nature Materials.

More than 2 billion people, approximately a quarter of the world's population, lack access to clean drinking water. A new, portable and affordable water filtration solution created by researchers at The University of Texas at Austin aims to change that.

The way buildings consume energy will continue to undergo massive upheavals in the next decade to adapt to electricity decarbonization efforts and the accompanying electrical grid changes. Improving building energy efficiency and flexibility—which account for three-fourths of electricity consumption and one-third of carbon dioxide emissions in the United States—offers an opportunity to achieve net-zero greenhouse gas emission goals.

A team in Cornell Engineering has created a new lithium battery that can charge in under five minutes—faster than any such battery on the market—while maintaining stable performance over extended cycles of charging and discharging.

A research team from Purdue University's Department of Computer Science and Institute for Digital Forestry, with collaborator Sören Pirk at Kiel University in Germany, has discovered that artificial intelligence can simulate tree growth and shape.

Electrical impedance tomography (EIT) is a non-destructive imaging technique used to visualize the interior of materials. In this method, an electric current is injected between two electrodes, creating an electric field, and other electrodes measure distortions caused by the presence of foreign objects inside the material.

The sustainably powered, electrochemical reduction of carbon dioxide (CO2) into useful chemicals and feedstock could help to mitigate greenhouse gas emissions, allowing industries to reuse released CO2 in beneficial ways. Most of the strategies for realizing this introduced so far, however, have notable limitations, including a poor stability over long periods of time.

We typically don't think about it while doing it, but walking is a complicated task. Controlled by our nervous system, our bones, joints, muscles, tendons, ligaments and other connective tissues (i.e., the musculoskeletal system) must move in coordination and respond to unexpected changes or disturbances at varying speeds in a highly efficient manner. Replicating this in robotic technologies is no small feat.

A research team led by Lawrence Berkeley National Laboratory (Berkeley Lab) has developed "supramolecular ink," a new technology for use in OLED (organic light-emitting diode) displays or other electronic devices. Made of inexpensive, Earth-abundant elements instead of costly scarce metals, supramolecular ink could enable more affordable and environmentally sustainable flat-panel screens and electronic devices.

Researchers at NYU Tandon School of Engineering achieved a major breakthrough in Redox Flow Desalination (RFD), an emerging electrochemical technique that can turn seawater into potable drinking water and also store affordable renewable energy.

We are tasking our computers with processing ever-increasing amounts of data to speed up drug discovery, improve weather and climate predictions, train artificial intelligence, and much more. To keep up with this demand, we need faster, more energy-efficient computer memory than ever before.

Organic mixed ionic–electronic conductors (OMIECs) are a highly sought-after class of materials for non-conventional applications, such as bioelectronics, neuromorphic computing, and bio-fuel cells, due to their two-in-one electronic and ionic conduction properties.

In the latest of a series of innovative designs for wearable sensors that use sweat to identify and measure physiological conditions, Caltech's Wei Gao, assistant professor of medical engineering, has devised an "electronic skin" that continuously monitors nine different markers that characterize a stress response.

The gator was found with its snout poking through the ice and his heart "beating three beats per minute."
