Star formation in galactic centers

Stars form from the gas and dust in molecular clouds via a series of complex processes that are currently only partly understood, and the evolution of these clouds drives the evolution of the stellar populations in the universe. ...

Mammoth moves: frozen cells come to life, but only just

A team of scientists in Japan has successfully coaxed activity from 28,000-year-old cells from a frozen mammoth implanted into mouse cells, but the woolly mammal is unlikely to be walking among us soon.

Chandra detection of a circumnuclear torus

Most galaxies host supermassive black holes at their nuclei, each with millions or billions of solar-masses of material. There is thought to be a torus of dust and gas around the black holes, and an accreting disk that becomes ...

Why does nuclear fission produce pear-shaped nuclei?

Nuclear fission is a process in which a heavy nucleus split into two. Most of the actinides nuclei (plutonium, uranium, curium, etc) fission asymmetrically with one big fragment and one small. Empirically, the heavy fragment ...

Magic number colloidal clusters

Complexity in nature often results from self-assembly, and is considered particularly robust. Compact clusters of elemental particles can be shown to be of practical relevance, and are found in atomic nuclei, nanoparticles ...

A 3-D imaging technique unlocks properties of perovskite crystals

A team of materials scientists from Penn State, Cornell and Argonne National Laboratory have, for the first time, visualized the 3-D atomic and electron density structure of the most complex perovskite crystal structure system ...

Genome-wide rules of nucleosome phasing in drosophila

LMU researchers have, for the first time, systematically determined the positioning of the packing units of the fruit fly genome and discovered a new protein that defines their relationship to the DNA sequence.
