EAST LANSING, Mich. - For years, the city of Flint has been trying to fight another battle with lead...and it lies within the soil.

A new study, involving a Michigan State University researcher, has found that higher rates of Flint children showed elevated lead levels in their blood during drier months of the year, even before the switch to a new water supply. The findings suggest that lead contaminated soil is most likely the culprit especially in the older, more industrial areas of the city.

The research is published in the International Journal of Environmental Research and Public Health.

Peering deep into the heart of our home galaxy, the Milky Way, the NASA/ESA Hubble Space Telescope reveals a rich tapestry of more than half a million stars. Apart from a few, blue, foreground stars, almost all of the stars pictured in the image are members of the Milky Way nuclear star cluster, the densest and most massive star cluster in the galaxy. Hidden in the centre of this cluster is the Milky Way's resident supermassive black hole.

Most of us think nothing of rainfall or where it goes, unless it leads to flooding or landslides. But soil scientists have been studying how water moves across or through soil for decades. Daniel Hirmas, a professor at University of Kansas, and his team may be taking the study of soil hydrology to some exciting new territory. Territory that may help soil scientists manage water resources better.

Why is Hirmas trying to predict water movement in soil?

"There are a number of reasons why more accurate predictions of water flow is important. Better management of water resources is one," Hirmas says.

Lake Nona, Fla., March 30, 2016 -- Researchers at Sanford Burnham Prebys Medical Discovery Institute (SBP) have identified a protein complex that is required for conversion of "bad" white fat to "good" brown fat. The findings, published online in the Journal of Clinical Investigation, could help treat metabolic disorders such as obesity.

"Our study points to mTORC1--a protein complex that senses nutrient levels--as a key regulator of fat browning," said Sheila Collins, Ph.D., professor in SBP's Integrative Metabolism Program and senior author of the paper. "Therapies that promote browning, or an increase in brown fat-like cells within the typical white fat tissue, are being actively pursued as a way to help people burn more calories independent of exercise."

A survey of a major oil and natural gas-producing region in Western Canada suggests there may be a link between induced earthquakes and hydraulic fracturing, not just wastewater injection, according to a new report out this week in the journal Seismological Research Letters.

Hydraulic fracturing is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks to release the oil and natural gas trapped inside. That release brings the oil and natural gas up to the surface and with it comes water, chemical additives and other substances picked up during the injection process. All that fluid has to be disposed of and, often, it's reinjected underground into what's referred to as a wastewater injection well.

Superconducting materials have the characteristic of letting an electric current flow without resistance. The study of superconductors with a high critical temperature discovered in the 1980s remains a very attractive research subject for physicists. Indeed, many experimental observations still lack an adequate theoretical description. Researchers from the University of Geneva (UNIGE) in Switzerland and the Technical University Munich in Germany have managed to lift the veil on the electronic characteristics of high-temperature superconductors. Their research, published in Nature Communications, show that the electronic densities measured in these superconductors are a combination of two separate effects.
