Normal, dust-obscured galaxies in the epoch of reionization
Over the past decades, rest-frame ultraviolet (UV) observations have provided large samples of UV luminous galaxies at redshift (z) greater than 6 (refs. 1–3), during the so-called epoch of reionization. While a ...

A massive core for a cluster of galaxies at a redshift of 4.3
Massive galaxy clusters have been found that date to times as early as three billion years after the Big Bang, containing stars that formed at even earlier epochs1–3. The high-redshift progenitors of these galaxy...

Galaxy growth in a massive halo in the first billion years of cosmic history
Two extremely massive galaxies are seen 800 million years after the Big Bang, showing the rapid growth of early structure and marking the most massive halo known in that era.

Dusty starburst galaxies in the early Universe as revealed by gravitational lensing
A spectroscopic redshift survey of extraordinarily bright millimetre-wave-selected sources of carbon monoxide line emission — originating from star-forming molecular gas — shows that at least ten of these sour...

Block copolymers
The preparation of acid chloride of poly(propylene oxide), PPO, the synthesis of prepolymer poly(p-benzamide), and of block copolymers of poly(p-benzamide)-b-poly(propylene oxide) are reported. The preparation...
