In a paper appearing in Science Advances, Michigan State University researchers have unraveled a surprising genetic mystery centered on sugars found in what gardeners know as "tomato tar."
Every cuckoo is an adopted child—raised by foster parents, into whose nest the cuckoo mother smuggled her egg. The cuckoo mother is aided in this subterfuge by her resemblance to a bird of prey. There are two variants of ...
The emergence in the Neolithic of patrilineal social systems, in which children are affiliated with their father's lineage, may explain a spectacular decline in the genetic diversity of the Y chromosome observed worldwide ...
Cells buzz with millions of different biomolecules that diffuse chaotically through their substructures, yet they manage to ensure exquisite functional and spatial specificity.
The beginning of life is shrouded in mystery. While the intricate dynamics of mitosis are well-studied in the so-called somatic cells—the cells that have a specialized function, like skin and muscle cells—they remain ...
Closely related animal species can look physically different, but you might be surprised to learn that those differences can result not only from DNA sequence changes that alter proteins' structure or function, but also because ...
Bread wheat is one of the most important staple crops for millions of people and is apparently the largest cultivated and traded cereal worldwide. Bread wheat is a hexaploid species with three subgenomes (2n = 6x = 42, AABBDD) ...
