New quantum effect demonstrated for the first time: Spinaron, a rugby in a ball pit      (via sciencedaily.com)     Original source 

Experimental physicists have demonstrated a new quantum effect aptly named the 'spinaron.' In a meticulously controlled environment and using an advanced set of instruments, they managed to prove the unusual state a cobalt atom assumes on a copper surface. This revelation challenges the long-held Kondo effect -- a theoretical concept developed in the 1960s, and which has been considered the standard model for the interaction of magnetic materials with metals since the 1980s.

A potentially cheaper and 'cooler' way for hydrogen transport      (via sciencedaily.com)     Original source 

Researchers have developed a new hydrogen energy carrier material capable storing hydrogen energy efficiently and potentially more cheaply. Each molecule can store one electron from hydrogen at room temperature, store it for up the three months, and can be its own catalyst to extract said electron. Moreover, as the compound is made primarily of nickel, its cost is relatively low.

Do or dye: Synthetic colors in wastewater pose a threat to food chains worldwide      (via sciencedaily.com)     Original source 

Dyes widely used in the textile, food and pharmaceutical industries pose a pressing threat to plant, animal and human health, as well as natural environments around the world, a new study has found. Billions of tons of dye-containing wastewater enter water systems every year, and a group of researchers say that new sustainable technologies including new membrane-based nano-scale filtration are needed to solve the issue, adding that legislation is needed to compel industrial producers to eliminate colorants before they reach public sewage systems or waterways.

Diapers can be recycled 200 times faster with light      (via sciencedaily.com)     Original source 

More than 100,000 tons of diapers are disposed of annually in Germany. Vast amounts of valuable resources, such as diaper liners, end up in the trash. The liners consist of special polymers, so-called superabsorbers. Researchers have now succeeded in considerably improving their complex recycling process. They use UV radiation to degrade the chemical chains that keep the polymers together. No chemicals are needed. Recycling at room temperature is 200 times faster than conventional recycling. The recycled polymers can then be processed to new adhesives and dyes.

Sunflower extract fights fungi to keep blueberries fresh      (via sciencedaily.com)     Original source 

Opening a clamshell of berries and seeing them coated in fuzzy mold is a downer. And it's no small problem. Gray mold and other fungi, which cause fruit to rot, lead to significant economic losses and food waste. Now, researchers report that compounds from sunflower crop waste prevented rotting in blueberries. They suggest the food industry could use these natural compounds to protect against post-harvest diseases.

Biological fingerprints in soil show where diamond-containing ore is buried      (via sciencedaily.com)     Original source 

Researchers have identified buried kimberlite, the rocky home of diamonds, by testing the DNA of microbes in the surface soil. These 'biological fingerprints' can reveal what minerals are buried tens of meters below the earth's surface without having to drill. The researchers believe it is the first use of modern DNA sequencing of microbial communities in the search for buried minerals. The research represents a new tool for mineral exploration, where a full toolbox could save prospectors time and a lot of money,
