Four of the most widespread environmental toxins--lead, trihalomethanes (found in drinking water), ionizing radiation from indoor radon gas, and tobacco smoke--can cause serious damage to health even at very low levels, say researchers in the international medical journal PLoS Medicine.
What this means, say the researchers Donald Wigle of the University of Ottawa and Bruce Lanphear of Cincinnati Children’s Hospital Medical Center, is that there are simply no safe levels of exposure to these toxins and they must be "virtually eliminated to protect human health."
Children can suffer brain damage from being exposed to very low levels of lead, they say. Although the US Centers for Disease Control and Prevention does not recommend public health or medical action unless the blood lead level of children exceeds 0.48 micromoles/liter, several longitudinal studies of children found inverse relationships between IQ and blood lead levels over a range extending below 0.48 micromoles/liter. These studies found no evidence of a "safe" threshold.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
