Mums to be have known for some time that what they eat when pregnant affects their unborn child but now scientists believe that the diet of our mothers during pregnancy may even affect our predisposition to illnesses such as heart disease, diabetes and high blood pressure in late life.
Studies with animals have shown a link between diet and the life long health of offspring but experiments with pregnant women or unborn children is clearly not possible. Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have turned to embryonic human stem cells to provide the answers.
The scientists, led by Dr Lorraine Young at the University of Nottingham Division of Obstetrics and Gynaecology, are looking at the fundamental process of methylation. This is one of the ways that our bodies control which genes are working in which tissues and at what time by tagging some of our DNA with small chemical groups called methyl groups. The process is essential for controlling gene activity as an organism grows and develops into adulthood. Faults in this process are known to cause some rare developmental diseases but Dr Young’s group now believes that a foetus’ response to its mother’s diet could affect this process as well, leading to changes in gene activity and therefore susceptibility to illness in later life.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
