Dark Adaptation News Today

MMCA Cheongju Project is a series of regular exhibitions that transcend the boundaries of the conventional exhibition hall, expanding themes of “city” and “everyday spaces” into outdoor and public settings.

Estimating photosynthetic quantum yield makes plant phenotyping easy. However, plant samples must be dark-adapted, which is time-consuming and complicates measurement of the ratio of variable to maximum fluorescence (Fv/Fm). A research consortium led by scientists from Jiangnan University has developed an artificial intelligence method, known as least-squares support vector machine model (LSSVM), that makes rapid Fv/Fm calculations without dark adaptation. This high-throughput method saves time,...

763 NGC 1808 is barred spiral galaxy located in the southern constellation of Columba. It was discovered by Scottish astronomer James Dunlop from Australia, who describe it as a "faint nebula". It is a barred spiral with marked similarities to our home Milky Way Galaxy. NGC 1808 is distinguished by a peculiar nucleus, an unusually warped disk, and strange flows of hydrogen gas out from the central regions. Amidst all of this, because NGC 1808 is undergoing wi...

315 Messier 106 is a spiral galaxy lying 22 million light-years from Earth in the constellation Canes Venatici. It is a Seyfert galaxy with an active nucleus emitting radio waves and X-rays due to presence of a supermassive black hole actively consuming matter within its core. Violent churning of spiral arms, dust clouds, and sprays of ionized hydrogen can be seen revolving around the nucleus. The the irregular galaxy to its lower left is UGC7356 which lies a...
