A study links soil metals with cancer mortality

Fri, 20 Apr 18 00:07:10 -0700

Spanish epidemiologists and geologists have found associations between esophageal cancer and soils where lead is abundant, lung cancer and terrains with increased copper content, brain tumor with areas rich in arsenic, and bladder cancer with high cadmium levels. These statistical links do not indicate that there is a cause-effect relationship between soil type and cancer, but they suggest that the influence of metals from the earth's surface on the geographical distribution of tumors should be analyzed.



Spider silk key to new bone-fixing composite

Thu, 19 Apr 18 00:12:10 -0700

UConn researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.



A novel way of creating gold nanoparticles in water

Thu, 19 Apr 18 00:16:20 -0700

The discovery that water microdroplets can replace potentially toxic agents in the creation of gold nanoparticles and nanowires could help usher in a new era of 'green chemistry.'



Rare earth magnet recycling is a grind -- this new process takes a simpler approach

Thu, 19 Apr 18 00:05:20 -0700

A new recycling process developed at the US Department of Energy's Critical Materials Institute turns discarded hard disk drive magnets into new magnet material in a few steps, and tackles both the economic and environmental issues typically associated with mining e-waste for valuable materials.



Coho salmon die, chum salmon survive in stormwater runoff research

Wed, 18 Apr 18 00:14:20 -0700

In a recent paper published in the journal Environmental Pollution, scientists found that coho salmon became sick and nearly died, within just a few hours of exposure to polluted stormwater. But chum salmon showed no signs of ill-effects after prolonged exposure to the same water.



Novel thermal phases of topological quantum matter in the lab

Tue, 17 Apr 18 00:13:30 -0700

A quantum simulation of topological phases of matter at finite temperature has be realized for the first time by a group of researchers from Universidad Complutense, IBM, ETH Zurich, MIT and Harvard University. These findings open the door to unexpected applications in robust quantum technologies against thermal fluctuations such as quantum computers or memories.



A heavyweight solution for lighter-weight combat vehicles

Fri, 13 Apr 18 00:10:10 -0700

Researchers at Pacific Northwest National Laboratory have developed and successfully tested a novel process -- called Friction Stir Dovetailing -- that joins thick plates of aluminum to steel. The new process will be used to make lighter-weight military vehicles that are more agile and fuel efficient.



Scientists use machine learning to speed discovery of metallic glass

Fri, 13 Apr 18 00:14:20 -0700

Blend two or three metals together and you get an alloy that usually looks and acts like a metal, with its atoms arranged in rigid geometric patterns. But once in a while, under just the right conditions, you get something entirely new: a futuristic alloy called metallic glass. Now new research reports a shortcut for discovering and improving metallic glass -- and, by extension, other elusive materials -- at a fraction of the time and cost.



Artificial intelligence accelerates discovery of metallic glass

Fri, 13 Apr 18 00:14:40 -0700

Combining artificial intelligence with experimentation sped up the discovery of metallic glass by 200 times. The new material's glassy nature makes it stronger, lighter and more corrosion-resistant than today's best steel.



Recycling experts hit milestone in quest for zero-waste phone

Thu, 12 Apr 18 00:09:40 -0700

UBC researchers have perfected a process to efficiently separate fiberglass and resin -- two of the most commonly discarded parts of a cellphone -- bringing them closer to their goal of a zero-waste cellphone.



A tool based on the use ofcarbon nanoparticles enables detection of antidepressants in urine samples

Tue, 10 Apr 18 00:02:00 -0700

The test can be used to monitor therapeutic dosages, for cases of intoxication due to overdose or at a forensic level.



Cheaper, less toxic and recyclable light absorbers for hydrogen production

Tue, 10 Apr 18 00:01:50 -0700

Achieving artificial photosynthesis in solution remains limited by the use of costly and toxic metal-based compounds to harvest light. Researchers at CNRS, CEA and the Université Grenoble Alpes propose an efficient alternative using semiconductor nanocrystals (also called quantum dots) based on cheaper and less toxic elements, such as copper, indium and sulfur.



Phononic SEIRA -- enhancing light-molecule interactions via crystal lattice vibrations

Mon, 09 Apr 18 00:13:30 -0700

Researchers from CIC-nanoGUNE (San Sebastián, Spain), in collaboration with the Donostia International Physics Center (San Sebastián, Spain), Materials Physics Center (CFM, CSIC-UPV/EHU, San Sebastián, Spain) and University of Oviedo demonstrate a new way to strongly couple infrared light and molecular vibrations, by utilizing phonon polariton nanoresonators made of hexagonal boron nitride, a Van der Waals material.



Pulling valuable metals from e-waste makes financial sense
Electronic waste -- including discarded televisions, computers and mobile phones -- is one of the fastest-growing waste categories worldwide. For years, recyclers have gleaned usable parts, including metals, from this waste stream. That makes sense from a sustainability perspective, but it's been unclear whether it's reasonable from an economic viewpoint. Now researchers report in ACS' journal Environmental Science
