Scientists at the Babraham Institute have discovered that conflict between genes inherited from our parents may affect our ability to adapt to life after birth, and have lasting effects on our weight. We inherit similar sets of genes from both our parents, but of a small number of genes only one of the copies is active, the copy from the other parent being ‘imprinted’ to be silent.
The research group, headed by Dr Gavin Kelsey has published a study in Nature Genetics which describes the effects of altering an imprinted gene in mice that specifies a controller of hormone action. This shows that imprinting has important effects on the way young interact with their mothers, and how they regulate their food intake and metabolism.
This work provides more evidence that instead of co-operating, some genes that we inherit from our parents can be in conflict. The imprinted genes received from fathers make greater demands on mothers, whilst imprinted genes from mothers are more conservative. It appears to be crucial that we have the right balance of imprinted genes.

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.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
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...
