Removal of Heavy Metals from Wastewater by Electromagnetic Superabsorbent Nanocomposites

Pollution caused by heavy metals is one of the serious concerns in the field of environmental protection and; therefore, researchers from University of Mazandaran, Iran, produced magnetic nanosorbent at laboratorial scale to purify the contaminated waters.

This research deals with the production of biocompatible electromagnetic superabsorbent nanocomposites, and their application in the removal of pollutants, including lead, cadmium and cobalt, from drinking water. The nanosorbent has been produced through a simple and cost effective method, and it has good performance. After the removal of heavy metals, the produced nanosorbent can be separated from the cycle by using a magnetic field and it can be reused.

Funky Light Signal From Colliding Black Holes Explained

Entangled by gravity and destined to merge, two candidate black holes in a distant galaxy appear to be locked in an intricate dance. Researchers using data from NASA's Galaxy Evolution Explorer (GALEX) and NASA's Hubble Space Telescope have come up with the most compelling confirmation yet for the existence of these merging black holes and have found new details about their odd, cyclical light signal.

Study Contrasts Effects of Two Types of SoCal Fires

A new University of California/NASA study finds Southern California autumn wildfires driven by Santa Ana winds have been 10 times as costly in the past 20 years as summer wildfires, even though both types of fires have consumed about the same total acreage. Both types of fires are predicted to increase by midcentury, but non-Santa Ana fires are expected to increase more.

Team announces breakthrough observation of Mott transition in a superconductor

An international team of researchers, including the MESA+ Institute for Nanotechnology at the University of Twente in The Netherlands and the U.S. Department of Energy’s Argonne National Laboratory, announced in Science the observation of a dynamic Mott transition in a superconductor.

The discovery experimentally connects the worlds of classical and quantum mechanics and illuminates the mysterious nature of the Mott transition. It also could shed light on non-equilibrium physics, which is poorly understood but governs most of what occurs in our world. The finding may also represent a step towards more efficient electronics based on the Mott transition.

Fortifying Computer Chips for Space Travel

Berkeley Lab's particle accelerator blasts microprocessors with high-energy beams to toughen them up.

Space is cold, dark, and lonely. Deadly, too, if any one of a million things goes wrong on your spaceship. It’s certainly no place for a computer chip to fail, which can happen due to the abundance of radiation bombarding a craft. Worse, ever-shrinking components on microprocessors make computers more prone to damage from high-energy radiation like protons from the sun or cosmic rays from beyond our galaxy.
