- 'Milestone': Scientists claim to build synthetic cell, raising concerns in step toward artificial life
Scientists at the University of Minnesota claim to have built the most life-like synthetic cell, SpudCell, assembled entirely from nonliving components capable of growth, DNA replication, division, and passing traits to offspring. The synthetic cells require lab-controlled nutrients and external components to survive and have not undergone peer review, with researchers acknowledging limitations like 30% genome inheritance after five generations.
- How natural selection really shaped humanity
The article discusses how natural selection has significantly influenced human evolution through adaptation to environmental pressures. It highlights the prevalence of evolutionary adaptations in shaping human traits and survival strategies.
