Planets form in disks of gas and dust around young stars. The disk molecular reservoirs and
their chemical evolution affect all aspects of planet formation, from the coagulation of dust …

The single chirality of biological molecules in terrestrial biology raises more questions than
certitudes about its origin. The emergence of biological homochirality (BH) and its …

The fundamental roles that peptides and proteins play in today's biology makes it almost
indisputable that peptides were key players in the origin of life. Insofar as it is appropriate to …

The pristine sample from the near-Earth carbonaceous asteroid (162173) Ryugu collected
by the Hayabusa2 spacecraft enabled us to analyze the pristine extraterrestrial material …

The search for evidence of extraterrestrial life in our Solar System is currently guided by our
understanding of terrestrial biology and its associated biosignatures. The observed …

The interstellar medium is characterized by a rich and diverse chemistry. Many of its
complex organic molecules are proposed to form through radical chemistry in icy grain …

Despite the generally hostile nature of the environments involved, chemistry does occur in
space. Molecules are seen in environments that span a wide range of physical and chemical …

Cell membranes are a key element of life because they keep the genetic material and
metabolic machinery together. All present cell membranes are made of phospholipids, yet …

Although it is generally accepted that amino acids were present on the prebiotic Earth, the
mechanism by which α‐amino acids were condensed into polypeptides before the …

Our Sun and planetary system were born about 4.5 billion years ago. How did this happen,
and what is the nature of our heritage from these early times? This review tries to address …
