The idea that a woman’s emotional state during pregnancy affects her unborn child has persisted for centuries and has, in recent years, been supported by science. Called the "fetal programming hypothesis," it theorizes that certain disturbing factors occurring during certain sensitive periods of development in utero can "program" set points in a variety of biological systems in the unborn child. This, then, affects the ability of those biological systems to change later in life, resulting in difficulties adapting physiologically and ultimately predisposing a child to disease and disorder.
We decided to investigate the affect of high levels of anxiety during a woman’s pregnancy on her child’s susceptibility for attention deficits, hyperactivity, acting out and anxiety disorders in childhood. We also wanted to learn whether there are specific vulnerable periods during the pregnancy in which this anxiety "programs" the child’s biological system, thus increasing the fetus’ susceptibility for such disorders.
We evaluated data collected on 71 normal mothers and their 72 first-born children during pregnancy and when their children were 8 or 9. The mothers completed questionnaires to measure their anxiety levels throughout their pregnancy. When the children were 8 or 9, the mothers, a teacher, and an impartial observer completed questionnaires to measure the child’s attention and hyperactivity, acting-out behavior and anxiety level.

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...
'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...
