The enzyme, TPPII, has previously been linked to making people feel hungry, but Jonathan Graff and colleagues now show that it may be even more deeply involved…
The key to creating a vaccination lies in knowing which parts of the pathogen to target with which antibodies. A new study by David Heckerman and colleagues…
Microalgae have turned out to be a potential alternative to the use of synthetic sources for these ingredients. Spirulina is a type of microalgae that has been…
These molecules bind to the protein actin which is implicated in cell movement and cell division. According to experimental results published recently in…
The idea that MMTV is involved in human breast cancer has been around for over 50 years. In the 1990s, researchers detected MMTV in human breast tumors, but…
Early on in development, the mass of undifferentiated cells that make up the embryo must take the first steps in deciding how to arrange themselves into…
The great novelty of this work compared to others of a similar nature is the implantation of stem cells using a catheter and not through open surgery, used to…
Campylobacters occur widely as part of the intestinal flora of many warm-blooded animals and birds, particularly chickens and turkeys, and can be carried in…
The mathematicians, funded by the Biotechnology and Biological Sciences Research Council (BBSRC), will investigate how the different cellular components of the…
Scientists had previously established that certain types of aphids live in colonies where they are used as a food source by a neighbouring colony of ants. The…
Drawing upon a series of observations and experiments, Duke University Medical Center investigators postulate that the beneficial bacteria in the appendix that…
The answers, published online by Nature Genetics on October 7, 2007, provide the first evolutionary history of the duplications in the human genome that are…
A KSHV protein called latency-associated nuclear antigen, LANA for short, helps the virus hide out from the immune system in infected cells. When LANA takes…
The cell type has very similar properties to so-called Y retinal ganglion cells, which were first described in cats in 1966. Upon the Y-cell's discovery,…
Chemicals and drugs often cause health problems by altering gene expression and other cell activity, and research on these processes — called toxicogenomic…
