The complexity of living organisms is encoded within their genes, but where do these genes come from? Researchers resolved outstanding questions regarding the origin of small regulatory genes, and described a mechanism that creates their DNA palindromes. Under suitable circumstances, these palindromes evolve into microRNA genes.

Despite the Roman Empire's extensive military and cultural influence on the nearby Balkan peninsula, a DNA analysis of individuals who lived in the region between 1 and 1000 CE found no genetic evidence of Iron Age Italian ancestry. Instead, a new study has revealed successive waves of migrations from Western Anatolia, central and northern Europe, and the Pontic-Kazakh Steppe during the Empire's reign.

Engineers have developed a bio-compatible ink that solidifies into different 3D shapes and structures by absorbing ultrasound waves. Because the material responds to sound waves rather than light, the ink can be used in deep tissues for biomedical purposes ranging from bone healing to heart valve repair.

Researchers have discovered that misreading of therapeutic mRNAs by the cell's decoding machinery can cause an unintended immune response in the body. They have identified the sequence within the mRNA that causes this to occur and found a way to prevent 'off-target' immune responses to enable the safer design of future mRNA therapeutics.
