  A reflection on how biology should be taught

  This essay argues that biology education often reduces major discoveries to memorization, rather than conveying the wonder and open questions behind them. It highlights classic examples such as embryonic differentiation and Oswald Avery’s experiments showing DNA as the transforming principle of heredity.

  Large genome models generate bacteriophage genomes

  Researchers at Stanford used large genome models to generate DNA sequences for viruses that infect bacteria. The synthetic genomes produced viruses closely related to an existing bacteriophage, but with some distinctive features that may be difficult to evolve naturally. The work raises questions about how similar models could eventually be used to design viruses that target vertebrates.

  ICE Collected Nearly 1 Million DNA Samples Last Year

  A Wired report says U.S. Immigration and Customs Enforcement collected nearly 1 million DNA samples last year, including from young children. The article links the collection to federal DNA databases and raises concerns about the scale and scope of the practice.

  DNA study may explain a Medici family mystery after 400 years

  Researchers analyzed DNA from Medici remains to investigate a long-standing family mystery and found evidence pointing to malaria as a likely cause. The study uses modern genetic analysis to shed light on a historical question that had remained unresolved for centuries.

  Scientists build a cell from scratch that grows and divides

  Researchers have assembled a synthetic cell from nonliving biomolecules enclosed in a membrane and observed it grow, replicate its DNA, and divide. The work is an early proof of concept for building life-like systems from scratch, but the cell still depends on external supplies and is not considered alive.
