David Speicher and colleagues explain that ectopic pregnancy happens when an embryo does not attach normally inside the mother's uterus, but instead attaches and begins growing elsewhere. Most occur inside one of the Fallopian tubes, which link the ovaries to the uterus.
Left undiagnosed, EP can burst the Fallopian tube and result in bleeding that is the second most common cause of maternal death early in the first trimester of pregnancy. EP is difficult for doctors to diagnose, and scientists long have searched for substances present in the blood of women with EP that could be the basis for a test.
The scientists describe discovery of such proteins in blood analyzed from women with ectopic pregnancies and compared it to blood of women with normal pregnancies. They identified almost 70 proteins occurring in unusual levels in the blood in EPs. One of those proteins is called Adam12 and it might be a particularly good early warning sign for EP, since it appears at levels that are 20 times lower than in normal pregnancies. "The next step is clearly to test the candidate biomarkers on a larger, independent patient group, both individually and in multi-biomarker panels," the report states.

A Swedish-German team of researchers has cleared up a key process for the artificial production of silk. With the help of the intense X-rays from DESY's...
For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
