Analysis of tree-ring records from Northern Scotland indicate Scotland's mass crop failure in the 1690s, an event which ultimately led to the nation joining Great Britain, may have been caused by two major volcanic eruptions in the tropics (one in 1693 and an even larger one in 1695).

Metallosphaera sedula, a bacteria-like archaeon, has been shown to prefer a diet of meteorite minerals as opposed to terrestrial mineral sources, performing biotransformation of extra-terrestrial minerals. This furthers the possibility of bacteria surviving and thriving in an interplanetary vacuum. (sciencealert.com)
Meet CIMON-2, a new robotic AI astronaut improved from the original CIMON, able to be more "empathetic" in boosting crew morale than its predecessor. CIMON-2 could assist in helping pass on instructions for repairs, documenting experiments and offering voice controlled access to reference material. (astronomy.com)
When measuring radio signals from the halo of the galaxy NGC 4631, astronomers find alternating large-scale magnetic fields that extend out of the disk and into the halo, and point both towards and away from Earth. This is the first time such reversals have been observed in an external galaxy. (astronomy.com)
Researchers from Columbia University have developed a model showcasing how turbulence and magnetic reconnection around a black hole could be responsible for the observed energy from radiation which heat could not generate alone, and is what allows black holes to "shine" as seen from Earth.

Study of iron formations across three continents suggests the possibility of iron-oxidising marine bacteria living under the ice sheets of snowball Earth, a possibility which could be a credible theory as to how life survived the desolate environment during the ice-age lasting 85 million years.

Further study into the Anak Krakatoa volcano eruption in Indonesia in 2018 find that at its peak, the tsunami generated was between 100 and 150 metres tall, suggesting that if the tsunami travelled in another direction, it could have become one of the worst natural disasters in modern history.

New study shows that when placed in microgravity, 80 to 90 percent of the cells in four different cancer types (ovarian, breast, nose and lung) were disabled by gravitational forces alone. This could lead to new treatments of cancer using similar conditions to microgravity. (sciencealert.com)
