Arsenic has a number of known serious health effects, including increased cancer risk, higher frequency of cardiovascular disease, and diabetes. Until now, it has not been possible to show any impact on fetuses and newborns, even though a few studies have suggested such consequences. A number of countries, especially poor ones, have high concentrations of arsenic in their well water. In Bangladesh, sediment containing arsenic has been carried with rivers for millennia, creating health risks for nearly half of the population.
In the current study, Anisur Rahman from ICDDRB (International Centre for Diarrhoeal Research) in Dhaka, Bangladesh, and a doctoral candidate at the Unit for International Maternal and Child Health (IMCH) at Uppsala University, Sweden, has shown that mothers who drink this arsenic-tainted water run an increased risk of having a miscarriage or losing their child in its first year.
This is the first time statistically significant effects have been shown. They were apparent even at relatively low levels of concentration of arsenic, 50 micrograms/liter. The findings are based on more than 29,000 pregnancies and were gathered in Matlab, Bangladesh, in a collaborative effort involving ICDDRB, Uppsala University, and the Karolinska Institute.
“The study shows how important it is for the population to get arsenic-free water as soon as possible, and that pregnant women must be given priority in this work,” says Lars-Åke Persson, professor of international child health at Uppsala University.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
