Computer scientists worldwide have been developing a wide range of artificial intelligence (AI) systems. Some of these systems rely on an individual AI agent, while others consist of multiple interacting agents that exchange ...

Many animal species, ranging from peacocks and birds of paradise to some lizards, fish and beetles, display physical features or ornaments that can attract potential mates. These ornaments can include colorful plumage, elaborate ...

Cats, dogs, wolves and other agile four-legged animals can easily jump and squeeze through tight spaces while moving at high speed. Reproducing similar agile motions and skills in quadrupedal robots has so far proved challenging.

Electrons, particles that carry a negative electric charge, typically move through materials. At low densities and temperatures, however, the electrical repulsion between them can overpower their tendency to move, prompting ...

For robots to be successfully deployed in real-world environments, humans should trust them enough to cooperate with them. Some roboticists have been trying to determine whether users perceive robots that exhibit socially ...

Legged robots, robotic systems with legs that typically resemble those of animals or humans, could be advantageous for completing tasks in home environments or populated, dynamic spaces. These robots may look like humans ...

Fuel cells, devices that generate electricity by converting the chemical energy of hydrogen or other fuels via electrochemical reactions, are promising solutions for powering large electric vehicles, industrial sites and ...

Detecting short-wave infrared (SWIR) light, a region of the electromagnetic spectrum just beyond the light visible to the human eye, could be advantageous for many real-world applications. For instance, it could enable more ...

Roses are known for their thorns, the sharp structures that can sting and prickle the skin. Thorns, botanically known as prickles, are thought to discourage animals from feeding on plants and may also help climbing roses ...

Evaporation, the process by which water becomes vapor and disperses into the environment, draws heat from its surroundings. This heat, also known as atmospheric thermal energy, is abundant but diffuse, making it difficult ...

The universe is known to be expanding at an accelerating rate. Physicists typically attribute this acceleration to dark energy, a mysterious component of the universe that exerts negative pressure, causing space to expand ...

The human brain continuously receives information from inside the body that helps detect physical needs and emotional states, such as a racing heartbeat, shortness of breath, hunger, thirst, pain and body temperature. Its ...

Chronic pain, pain that persists or returns for more than three months, can affect people's emotional well-being and is often accompanied by difficulty concentrating or remembering things. While they can be effective for ...

Superconductors are materials that carry electrical current with zero resistance below a specific critical temperature. In conventional superconductors, the transition to superconductivity generally occurs at very low temperatures.

Lithium-ion batteries (LiBs) power electric vehicles and most existing electronics, ranging from laptops to smartphones, tablets, smart appliances and wearable devices. These batteries charge and discharge by moving lithium ...
