Discovery of Russia's Last Royal Family Remains
In 2007, skeletal remains identified as those of Alexei Nikolaevich, Tsarevich of Russia, and his sister Grand Duchess Anastasia were found in a grave near Yekaterinburg, Russia. This significant discovery followed years of investigation into the fate of the last Romanov family, executed in 1918 during the Russian Revolution. Forensic analysis confirmed the identities through DNA testing, providing closure to a long-standing mystery regarding their demise and confirming historical accounts of execution.

In London, scientists presented significant findings from DNA analysis of a Neanderthal skeleton that bolster the 'Out of Africa' theory of human evolution. The research suggests that modern humans can trace their lineage back to an 'African Eve' who lived between 100,000 and 200,000 years ago. This discovery has substantial implications for understanding human ancestry and migration patterns. The findings were announced at a notable symposium focusing on the genetic heritage of humans.

Francis Crick and James Watson published a groundbreaking paper in the journal Nature, detailing the helical structure of deoxyribonucleic acid (DNA). This paper proposed a double helix model of DNA, suggesting a method for genetic information storage and replication. The research built upon the foundational work of other scientists including Rosalind Franklin and Erwin Chargaff, ultimately paving the way for modern genetics. The model's elegant structure illustrated how nucleotides pair specifically, leading to advancements in molecular biology and genetics.
