Artificial intelligence (AI) systems are computational models that can learn to identify patterns in data, make accurate predictions or generate content (e.g., texts, images, videos or sound recordings). These models can reliably complete various tasks and are now also used to carry out research rooted in different fields.

Over the past few decades, some AI models have proved promising for the early diagnosis and study of specific diseases or neuropsychiatric conditions...

When we hear about moving objects with electricity, most of us imagine a “pulling force.” Positive and negative charges attract each other, drawing objects together. It is natural to think that this attractive force—known as electrostatic force—is what makes things move.

However, this force is not very strong, and it has not been suitable for driving large machines in our daily lives. For that reason, most practical motors rely on a different mechanism. For example, the motors in electric fans and electric vehicles do not use electricity directly to create motion...

Simulated lunar dirt can be turned into extremely durable structures, potentially paving the way to more sustainable and cost-effective space missions, a new study suggests. Using a special laser 3D printing method, researchers melted fake lunar soil—a synthetic version of the fine dusty material on the moon surface, called regolith simulant—into layers and fused it with a base surface to manufacture small, heat-resistant objects.

If utilized on the lunar surface, the material may help build sturdy, nontoxic habitats and tools for future astronauts, capabilities that would be vital to the NASA Artemis missions that aim to establish a long-term human presen...

A large new study suggests that higher levels of a common amino acid called tyrosine may be linked to a shorter lifespan in men.

The research, published recently in the journal Aging, examined whether blood levels of two amino acids, phenylalanine and tyrosine, were connected to how long people live.

Amino acids are building blocks of protein. They are found in protein-rich foods such as milk, eggs and meat, and are also sold as dietary supplements.

Researchers from the University of Hong Kong and the University of Georgia analyzed health and genetic data from more than 270,000 people in the U.K. Biobank, a large long-term health study in the U.K.

At first, both amino acids appeared to be tied to a higher risk of death...
