The reproductive system of this insect will be a model to understand stem cells better and make progress in their future use to treat certain human pathologies. The Andalusian Ministry of Innovation, Science and Enterprise has financed this project with 218,000 euros as part of their program of excellence.
Stem cells play an essential role in growth, as they allow the generation of different types of cells like neurones and egg cells, and the maintenance of adult tissues like blood, skin and the intestinal epithelium. In order to do so, it is necessary for stem cells to keep the potential that allows them to split almost unlimitedly and cause daughter cells that differ in different cell types.
In order to know more about stem cells, it is possible to test simple easy-to-study flies in a lab, like Drosophila melanogaster. This fly only has four chromosomes and its genome is already sequenced. Thanks to 80 years of study, we now know that many of the biological processes of Drosophila –despite the genetic simplicity of this fly- are very similar to vertebrates like mice and human beings.
This group of scientists have chosen to study fly’s ovary because, according to their leading researcher, Acaimo Gonzalez, ‘this organ is made up of just a few types of cells –including several types of stem cells- which allows us to identify stem cells unmistakably. Moreover, Drosophila allows us to make a genetic analysis of the biology of stem cells, which is essential for our research project’.
By analysing fly’s ovary, CABD’s scientists intend to show some light as to why a stem cell can split with the pass of time and remain indifferenced. Through the use of microarrays, scientists pursue to characterise those genes that are expressed in stem cells and study their function. According to Acaimo González, ‘it is essential to find out what genes are responsible for the maintenance of stem cells so that we can understand what stops stem cells from differentiating and keeps its proliferating potential unaffected’.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
