Twinkle twinkle baby star, 'sneezes' tell us how you are      (via sciencedaily.com)     Original source 

Researchers have found that baby stars discharge plumes of gas, dust, and magnetic flux from their protostellar disk. The protostellar disk that surrounds developing stars are constantly penetrated by magnetic flux, and if too much magnetic flux remained, the resulting object would generate a magnetic field stronger than any observed protostar. These newly discovered discharges of magnetic flux, or 'sneezes' as the researchers describes them, may be a vital step in proper star formation.

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.

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.

Inexplicable flying fox found in Hydra galaxy cluster      (via sciencedaily.com)     Original source 

High sensitivity radio observations have discovered a cloud of magnetized plasma in the Hydra galaxy cluster. The odd location and shape of this plasma defy all conventional explanations. Dubbed the Flying Fox based on its silhouette, this plasma will remain a mystery until additional observations can provide more insight.

Researchers envision sci-fi worlds involving changes to atmospheric water cycle      (via sciencedaily.com)     Original source 

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.
