Breaking up is hard to do (especially for sex chromosomes)

As chromosomes go, X and Y make an unlikely pair. The X is large and contains thousands of genes critical for life. The Y, by contrast, is little more than a nub. Its main purpose is to provide the instructions for initiating ...

Unraveling one of prion disease's deadly secrets

A molecular biologist at the University of Massachusetts Amherst who has for decades studied the nightmarish group of fatal diseases caused by prions—chronic wasting disease in deer, mad cow in cattle and its human analog—credits ...

Finally, machine learning interprets gene regulation clearly

In this age of "big data," artificial intelligence (AI) has become a valuable ally for scientists. Machine learning algorithms, for instance, are helping biologists make sense of the dizzying number of molecular signals that ...

Specific immune response of beetles adapts to bacteria

The immune system fends off pathogens in a wide variety of ways. For example, the immune system's memory is able to distinguish a foreign protein it has encountered before and to react with a corresponding antibody. Researchers ...

Rapid evolution: New findings on its molecular mechanisms

The mechanisms by which new species arise are still not fully understood. What are the evolutionary processes that drive the evolution of new species? Evolutionary biologists traditionally assumed that geographical barriers ...

Research uncovers elusive process essential to plant greening

Despite how essential plants are for life on Earth, little is known about how parts of plant cells orchestrate growth and greening. By creating mutant plants, UC Riverside researchers have uncovered a cellular communication ...
