DNA structure influences the function of transcription factors
Substances known as transcription factors often determine how a cell develops as well as which proteins it produces and in what quantities. Transcription factors bind to a section of DNA and control how strongly a gene in ...

Beta cells from love handles
Researchers at ETH Zurich have managed to use a synthetic genetic program to instruct stem cells taken from fatty tissue to become cells that are almost identical to natural beta cells. This brings them a major step closer ...

Complex grammar of the genomic language
A new study from Sweden's Karolinska Institutet shows that the 'grammar' of the human genetic code is more complex than that of even the most intricately constructed spoken languages in the world. The findings, published ...

Study suggests genetic basis for same-sex sexual behavior offers evolutionary advantage
(Phys.org)—A trio of researchers with the University of St. Andrews in the U.K. has found what appears to be an evolutionary advantage for same-sex sexual behavior in fruit flies. In their paper published in Proceedings ...
Researchers unwind the mysteries of the cellular clock
Human existence is basically circadian. Most of us wake in the morning, sleep in the evening, and eat in between. Body temperature, metabolism, and hormone levels all fluctuate throughout the day, and it is increasingly clear ...

Function follows form: Spatial structure determines transcription factor activity
Clay can be used in various forms for a range of objects such as cups, plates or bricks. Similarly, proteins can transform their structure and thus adapt their function and activity. Researchers at the Max Planck Institute ...

Like father, not like son: Brain and song structure in zebra finches are strongly influenced by the environment
The song of songbirds is a learned, complex behavior and subject to strong selective forces. However, it is difficult to tease apart the influence of the genetic background and the environment on the expression of individual ...
