A first: Scientists grow plants in soil from the Moon      (via sciencedaily.com) 

Scientists have, for the first time, grown plants in soil from the Moon. They used soil collected during the Apollo 11, 12 and 17 missions. In their experiment, the researchers wanted to know if plants would grow in lunar soil and, if so, how the plants would respond to the unfamiliar environment, even down to the level of gene expression.

Ice-capped volcanoes slower to erupt, study finds      (via sciencedaily.com) 

The Westdahl Peak volcano in Alaska last erupted in 1992, and continued expansion hints at another eruption soon. Experts previously forecasted the next blast to occur by 2010, but the volcano -- located under about 1 kilometer of glacial ice -- has yet to erupt again. Using the Westdahl Peak volcano as inspiration, a new volcanic modeling study examined how glaciers affect the stability and short-term eruption cycles of high-latitude volcanic systems -- some of which exist along major air transportation routes.

Astronauts: Blood clot expert to study blood flow, clot formation in zero gravity      (via sciencedaily.com) 

This was the first time a blood clot had been found in an astronaut in space, so there was no established method of treatment for DVT in zero gravity.

Researchers home in on Thera volcano eruption date      (via sciencedaily.com) 

Tree-ring, ice core and volcano experts teamed up to identify one of the most climatically impactful volcanic eruptions in 4,000 years -- Aniakchak II. In the process, they narrowed down potential dates for the Thera volcano eruption.

Volcanoes at fault if the Earth slips      (via sciencedaily.com) 

A new study has attributed the root cause of the 2016 Kumamoto earthquakes to specific geological damage. A relatively large dip-slip displacement was discovered at the site. The Futagawa strike-slip fault is a vertical break in the ground tracing a line southwest originating from Mount Aso.

Hubble sheds light on origins of supermassive black holes      (via sciencedaily.com) 

Astronomers have identified a rapidly growing black hole in the early universe that is considered a crucial 'missing link' between young star-forming galaxies and the first supermassive black holes. They used data from NASA's Hubble Space Telescope to make this discovery.

Hubble probes extreme weather on ultra-hot Jupiters      (via sciencedaily.com) 

Astronomers have discovered bloated Jupiter-sized worlds that are so precariously close to their parent star they are being roasted at seething temperatures above 3,000 degrees Fahrenheit. That's hot enough to vaporize most metals, including titanium. They have the hottest planetary atmospheres ever seen. Hubble astronomers are reporting on bizarre weather conditions on these sizzling worlds. It's raining vaporized rock on one planet, and another one has its upper atmosphere getting hotter rather than cooler because it is being 'sunburned' by intense ultraviolet (UV) radiation from its star.

Volcano monitoring at Mount Etna using fiber optic cables      (via sciencedaily.com) 

In order to understand and predict volcanic events even better, a better understanding of the diverse underground processes involved is required. A new way to detect such processes, even if they are very subtle, is to use fiber optic cables as sensors. The analysis of light that is backscattered in them when the cables are deformed by vibrations, for example, has now made it possible for the first time to determine the volcanic signature of the Sicilian volcano Etna very precisely.

Record broken: Hubble spots farthest star ever seen      (via sciencedaily.com) 

NASA's Hubble Space Telescope has established an extraordinary new benchmark: detecting the light of a star that existed within the first billion years after the universe's birth in the big bang -- the farthest individual star ever seen to date.

Describing the devastating eruption in Tonga      (via sciencedaily.com) 

On January 15, the volcano Hunga Tonga-Hunga Ha'apai devastated the nation of Tonga. The eruption triggered tsunamis as far afield as the Caribbean and generated atmospheric waves that travelled around the globe several times. Meanwhile, the volcano's plume shot gas and ash through the stratosphere into the lower mesosphere.

The oxidation of volcanoes -- a magma opus      (via sciencedaily.com) 

A new study unlocks the science behind a key ingredient -- namely oxygen -- in some of the world's most violent volcanoes. The research offers a new model for understanding the oxidation state of arc magmas, the lavas that form some volcanoes, such as the one that erupted dramatically in Tonga earlier this year. The plume from Tonga's underwater volcanic eruption on Jan. 15 rose 36 miles into the air. Ash from the volcano reached the mesosphere, Earth's third layer of atmosphere.

Water determines magma depth, a key to accurate models of volcanic activity, eruption      (via sciencedaily.com) 

Around the world, between 40 and 50 volcanoes are currently erupting or in states of unrest, and hundreds of millions of people are at risk of hazards posed by these potentially active volcanos. Yet, despite the profound hazards posed to human life and property by volcanic eruptions, humanity still cannot reliably and accurately predict them, and even when forecasts are accurately made by experts, they may not afford ample time for people to evacuate and make emergency preparations.
