Animal Models Offer Newborn Opportunity to Permanently Rescue Insulin-making Cells and Possibly Even Protect Against Future Onset
A common condition that leads to low birthweight babies may predispose the infants to obesity and diabetes later in life by denying cells in the pancreas access to the chemical signals they need to mature, according to researchers at the University of Pennsylvania School of Medicine. Moreover, the condition, which they have successfully modeled in rodents, may be reversed soon after birth by the administration of hormones that stimulate the maturation of the pancreatic beta cells, which produce insulin. Their findings suggest a way of preventing diabetes in people at-risk for the disease by boosting the creation of beta cells soon after birth.
According to Rebecca A. Simmons, MD, assistant professor in Penns Department of Pediatrics, "the condition, called intrauterine growth retardation (IUGR), is generally caused by the inability of a developing fetus to receive adequate nutrition and can effect as many as one in 10 newborns." Diminished fetal growth is due to a number of different processes such as high blood pressure and intrauterine infections. Epidemiological studies have also shown that there is a strong link between IUGR and the development of obesity and diabetes in adulthood. The Penn researchers believe the link may be due to the decreased formation of blood vessels in the pancreas.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
