Mitochondria are the body's "energy factories," and their proper function is essential for life. Inside mitochondria, a set of complexes called the oxidative phosphorylation (OxPhos) system acts like a biochemical assembly ...
During animal development, cells divide and arrange themselves in a coordinated way, eventually forming the embryo. The cells communicate with one another during this process through cell-surface receptors, which interact ...
The human body is a machine whose many parts—from the microscopic details of our cells to our limbs, eyes, liver and brain—have been assembled in fits and starts over the 4 billion years of our history.
Research led by the National Institute of Biological Sciences in Beijing has discovered that switching on a single dormant gene enables mice to regenerate ear tissue.
Anxiety, the psychological and physiological state characterized by an anticipation of potential threats and a heightened sense of vigilance, is regularly experienced by many humans worldwide. Research suggests that anxiety ...
The Sunda Shelf is home to a rich Pleistocene hominin fossil record, including specimens of Homo floresiensis, Homo luzonensis, Homo erectus, and archaic Homo. Much of the Sunda Shelf is submerged. At times during the Pleistocene, ...
Parental egg-care in fish traps them in an evolutionary dead-end through the loss of the chorion-hardening system, according to scientists from the Institute of Science Tokyo. Fish have diverse egg-caring strategies that ...
So much science starts with deciphering a genome, the blueprint for every being on Earth. With such roadmaps in hand, scientists can trace the evolutionary roots of human language, better understand the intelligence of other ...
For many New Zealanders, the Australian magpie is a familiar, if sometimes vexing, sight. Introduced from Australia in the 1860s, magpies are known for their territorial dive-bombing during the nesting season, which has cemented ...
A new study published in the Proceedings of the National Academy of Sciences reveals that smaller islands within the Wallacea biodiversity hotspot are crucial refuges for endangered vertebrates, providing higher-quality habitats ...
