Cosmic Titans: Unveiling the Origin of Supermassive Black Holes
Black holes with exceptionally large masses—over a million times the mass of the Sun, known as supermassive black holes (SMBHs)—are commonly found in the universe…
From Lava to Life: Early Earth’s Highly Oxidized Magma Ocean
New research suggests early Earth had a highly oxidized magma ocean, leading to a CO2 and SO2-rich atmosphere. The subsequent accretion of reducing materials was…
Rewriting Earth’s Early History: Scientists Discover High Iron Oxidation in Primordial Magma
New study sheds light on the composition of the Earth’s earliest atmosphere. Understanding the atmospheric and surface conditions of early Earth, especially before life originated,…
Peculiar Behavior of the Beetle Toramus Larvae – How and Why Do They Carry Their Exuviae?
The beetles of the family Erotylidae (Coleoptera: Cucujoidea) are morphologically and biologically diversified into six subfamilies, 10 tribes, and over 3,500 species. The tribe Toramini…
New Semiconductor Nanostructure for Efficient Quantum Electronics
Peculiar Bi provoked nanostructures in compound semiconductor nanowires controlled by atomically precise epitaxial crystal growth. Nanowire is a rod-structure with a diameter typically narrower than…
How and When Was Carbon Distributed in the Earth? New Experiment Raises Questions
It is generally accepted that planetary surfaces were covered with molten silicate, a “magma ocean,” during the formation of terrestrial planets. In a deep magma…
