Gray By shuffling DNA in and out of one gene, syphilis stays a step ahead of the immune system to resist eradication. The bacterium that causes syphilis, Treponema pallidum, likely uses a single gene to escape the immune system, […]

A mosaic world map made from various human teeth. Photographs made at the Osteological Collection, University of Tübingen. (Graphic design: Peter Jammernegg (photographer and graphic designer); Copyright: Katerina Harvati/ University of Tübingen) University of Tübingen researchers uncover dental traits revealing genetic relationships in humans, serving as proxy for DNA. Researchers at […]

Stanford researchers used advanced microscopy and mathematical modeling to discover a pattern that governs the growth of neurons in the flatworm brain, shown here. Using this technique, they hope to find patterns that guide the growth of cells in other parts of the body in order to pave the way […]

Chromosomes prepared from a malignant glioblastoma visualized by spectral karyotyping (SKY) reveal an enormous degree of chromosomal instability — a hallmark of cancer. Credit: NCI Center for Cancer Research (CCR) Mutations in 38 different types of cancer have been mapped by means of whole genome analysis by an international team […]

One wasp species has evolved the ability to recognize individual faces among their peers, signaling an evolution in how they have learned to work together. One wasp species has evolved the ability to recognize individual faces among their peers — something that most other insects cannot do — signaling an […]

Since humans possess similar genes to the axolotl, the researchers say, scientists may one day discover how to activate them to help speed wound repair or regenerate tissue. The type of salamander called axolotl, with its frilly gills and widely spaced eyes, looks like an alien and has other-worldly powers […]

A power drill helps a researcher extract a core from a tree included in the GenTree project. MEHDI PRINGARBE/INRA AVIGNON Faced with deforestation, climate change, invasive pests, and new diseases, many trees are in trouble. Foresters and conservationists are scrambling to save them, but can’t protect every stand of woods. […]

Szostak believes the earliest cells developed on land in ponds or pools, potentially in volcanically active regions. Ultraviolet light, lightning strikes, and volcanic eruptions all could have helped spark the chemical reactions necessary for life formation.
