Migratory birds such as the pied flycatcher typically have wintering locations in Africa close to others from the same breeding population. That means that birds breeding in the Netherlands run into each other again in Africa, ...

When it comes to choosing a partner, some species prefer males that stand out from the crowd. Evolutionary biologists call the resulting process negative frequency-dependent selection. It means that a male has a huge mating ...

University of Louisville researchers have discovered how a naturally occurring microbial compound may help protect the gut and support future treatment strategies for inflammatory bowel disease (IBD).

Strongly interacting quantum particles are key to some of the most fascinating phenomena in modern physics—from magnetism and superconductivity to topological states. Yet the complexity of such systems makes many of their ...

Vegetarians need not worry yet—plants will be on Earth for a long time to come. But not forever. The sun will ultimately determine the long-term existence of life on Earth. Its total energy output, called luminosity, has ...

Multiferroics are materials that exhibit more than one prominent "ferroic" property, such as ferromagnetism and ferroelectricity. One of their most advantageous features is that they allow engineers to control their magnetic ...

Neurodegenerative diseases affect tens of millions of people worldwide. Among these, Alzheimer's and Parkinson's diseases are the most common; in the United States alone, the Alzheimer's Disease Association and Parkinson's ...

Water is the most studied molecule on Earth, yet a surprisingly basic question has gone unanswered for decades: When water is squeezed into gaps just a few molecules wide—as happens inside nanoscale pores, membranes and biological ...

The Korea Research Institute of Standards and Science has developed an ultrasensitive immunoassay-based analytical platform that can detect and quantify trace amounts of "Small Excised Damaged DNA (sedDNA)" fragments generated ...

For nearly 50 years, scientists have suspected that microscopic marine plankton play a role in cloud formation over the oceans. Now, an experiment led by the University of Helsinki suggests that it may be more important than ...

Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as the outer membrane. Neuroscientists and medical researchers have long been trying to devise effective ...

Massive stars much bigger than our sun always come in pairs or groups, not alone. But astronomers don't fully understand how these groupings form. In a new study, astronomers using ALMA have serendipitously discovered a young ...
