Because energy resources in the body must be optimized as much as possible, a new paper says, tasks inherently related to survival, like immune function, take priority. Any leftover energy is…

A new study uses mouse genetics to demonstrate how a handful of workhorse signaling pathways interact to construct multiple structures that comprise the vertebrate body and how crosstalk between two…

Unique cellular and molecular mechanisms behind tooth renewal in American alligators may help science learn how to stimulate tooth regeneration in people, according to a new study. We regenerate…

Mammals have the ability to adapt to a range of the temperature. While physiological homeostasis has a lot to do with this, part of the reason why mammals can adapt to cold temperatures is the…

Brown and white fat cells in a living organism can be converted from one cell type to the other, according to a study using mice as a model organism. Two types of fat cells are found in mammals:…

Cloned fruit is widely sold in grocery stores.  Some of it is even cloned mutant fruit.  None of these fruits are labeled as such.  They aren't even regulated. You can't avoid this…

Researchers have found a way to turn bone marrow stem cells directly into brain cells, bypassing current cumbersome techniques and bringing about the possibility of simpler and safer methods. Stem…

In 2013, stem cell therapy is touted as the future of medicine by proponents in Europe and Asia while scientists in America urge caution. Contrast that to a decade ago, when the concern was that…

Scientists in the UK, Portugal and Germany solved the structure of kynurenine 3-monooxygenase (KMO), a protein implicated in the neurodegeneration (destruction of nerve cells) seen in diseases…

Men with Lynch syndrome, an inherited genetic condition linked to a higher risk of several types of cancer, face a higher lifetime risk of developing prostate cancer and appear to develop the disease…
