It is a well known fact that babies are harmed by tobacco smoke in numerous ways, but it has always been difficult to separate the effects of the mother smoking during pregnancy and passive smoking after birth. Dr Eva Lannerö’s doctoral thesis now provides new detailed knowledge on how exposure to tobacco smoke early in life influences the risk of developing allergy and asthma respectively.
The thesis, which is based on the so called BAMSE study, shows that smoking during pregnancy increases the chances of the child developing asthma. The study showed that children of mothers who had smoked while pregnant ran double the risk of developing asthma before the age of four. There was also a clear correlation between the number of cigarettes smoked and the risk of developing asthma.
Her thesis also shows that passive smoking in early childhood increases the risk of allergy. Four-year olds who were exposed to tobacco smoke when they were two months old had IgE antibodies (allergy antibodies) against one or more allergens in the blood more often than their coevals from non-smoking homes. The strongest correlation was observed for antibodies against cat allergens, which were twice as common in these children.
“This is particularly worrying as cat allergens are almost everywhere and are hard to avoid,” says Dr Lannerö. “We can’t say how many, but some of these children will definitely develop chronic asthma.”
Dr Lannerö’s studies also show that smoking during pregnancy is least common amongst the higher educated. Of the 4,000 interviewed mothers, 7 per cent of those with university-level education said that they had smoked while pregnant, as opposed to 20 per cent of those who had opted out of tertiary or secondary education. The data applies to mothers of children born between 1994 and 1996.
The BAMSE study is a project in which 4,100 Swedish children born between 1994 and 1996 have been monitored from birth in order that scientists can learn more about the impact of different environmental factors on the development of childhood allergy.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
