Water electrolyzers are promising devices that use electricity to split water into hydrogen and oxygen. If powered by solar cells or other renewable energy technologies, they could contribute to the sustainable production ...

Choosing whether to tackle or complete a difficult task often entails weighing the rewards that we could gain from this task against the mental effort it will require. For instance, a larger payment could make a challenging ...

Neutron stars, the extremely dense remains of massive stars that exploded at the end of their lives, are widely studied astrophysical objects. Some of these stars, known as pulsars, spin and send out beams of radio waves, ...

Carbon dioxide (CO2) is one of the main gases contributing to climate change on Earth. Removing this gas directly from the air could help to limit climate change, alongside other efforts to reduce emissions from industrial ...

Quantum technologies rely on qubits, units of information that can exist in combinations of the states 0 and 1 instead of being limited to one or the other like conventional bits. Qubits can become entangled, which means ...

Obsessive–compulsive disorder (OCD) is a psychiatric condition characterized by recurrent obsessions, or unwanted thoughts, typically accompanied by repeated actions that seem difficult to control, also known as compulsions. ...

When designing new computer chips, engineers need to make various decisions about how to connect their underlying components while efficiently using limited space. Planning these connections involves combinatorial optimization, ...

Snakes can elicit a wide range of human responses, including fear, disgust, awe and admiration. Past studies suggest that both humans and nonhuman primates, such as monkeys and apes, tend to quickly notice snakes in their ...

Adolescence, the critical developmental stage between childhood and adulthood, is often marked by significant changes in friendships, appearance, preferences and attitudes. For some young people, it can be a tumultuous period ...

Moral language—words and phrases that express ideas about right and wrong, virtues, fairness, harm and social obligations—is widely used in social media posts and other online content. Posts containing moral language sometimes ...

Earwigs, small, elongated insects with distinctive pincers at the rear of their abdomens, have little reason to enter open water. While many earwig species are attracted to damp environments, they typically avoid open water. ...

Over the course of their lives, humans and other animals can learn to connect specific actions or cues to a desirable outcome. This process, called reward learning, is known to play a role in some mental health conditions, ...

Solar cells, devices that convert energy from sunlight into electricity, are being deployed in increasing numbers in many countries. While most cells on the market today are based on silicon, recent studies have highlighted ...

Classical computers can temporarily store the information required to perform specific tasks in a short-term memory component known as RAM (random access memory). This component allows computer processors to retrieve information ...

When the brain forms memories of past experiences, it typically encodes various information, including what happened, where it happened and the order in which events unfolded. The hippocampus is one of the primary brain regions ...
