Pacific cities much older than previously thought      (via sciencedaily.com)     Original source 

New evidence of one of the first cities in the Pacific shows they were established much earlier than previously thought, according to new research. The study used aerial laser scanning to map archaeological sites on the island of Tongatapu in Tonga, showing Earth structures were being constructed in Tongatapu around AD 300.

Quantum breakthrough when light makes materials magnetic      (via sciencedaily.com)     Original source 

The potential of quantum technology is huge but is today largely limited to the extremely cold environments of laboratories. Now, researchers have succeeded in demonstrating for the very first time how laser light can induce quantum behavior at room temperature -- and make non-magnetic materials magnetic. The breakthrough is expected to pave the way for faster and more energy-efficient computers, information transfer and data storage.

Boreal forest and tundra regions worst hit over next 500 years of climate change, study shows      (via sciencedaily.com)     Original source 

Modelling climate change over a 500 year period shows that much of the boreal forest, the Earth's northernmost forests and most significant provider of carbon storage and clean water, could be seriously impacted, along with tundra regions, treeless shrublands north of the boreal forest that play a significant role in regulating the Earth's climate.

Human activity is changing the way water flows between the Earth and atmosphere in complex ways and with likely long-lasting consequences that are hard to picture. Researchers enlisted water scientists from around the globe to write story-based scenarios about the possible futures humanity is facing but perhaps can't quite comprehend yet. The results are part of a creative pathway to understand atmospheric water research with an eye towards the potential economic and policy issues that may be just beyond the horizon.

'Tug of war' tactic enhances chemical separations for critical materials      (via sciencedaily.com)     Original source 

Lanthanide elements are important for clean energy and other applications. To use them, industry must separate mixed lanthanide sources into individual elements using costly, time-consuming, and waste-generating procedures. An efficient new method can be tailored to select specific lanthanides. The technique combines two substances that do not mix and that prefer different types of lanthanides. The process would allow for smaller equipment, less use of chemicals, and less waste production.
