Why the Brain’s Connections to the Body Are Crisscrossed
In all bilaterally symmetrical animals, from humans down to simple worms, nerves cross from one side of the body to the opposite side of the brain. Geometry may explain why.
She Tracks the DNA of Elusive Species That Hide in Harsh Places
On Mount Everest and in the Peruvian Andes, Tracie Seimon uses DNA to study how species and ecosystems respond to climate change, pathogens and other influences.
Primitive Asgard Cells Show Life on the Brink of Complexity
As researchers race to cultivate more of the intriguing cells from the deep seafloor, the few cells now growing in labs are giving us our best glimpses of the forerunners of all complex life.
Animal Mutation Rates Reveal Traits That Speed Evolution
The first large-scale comparison of mutation rates gives insights into how quickly species can evolve.
What Has the Pandemic Taught Us About Vaccines?
Should Covid-19 vaccines be judged by how well they prevent disease or how well they prevent death? Anna Durbin, a public health expert and vaccine researcher, talks with Steven Strogatz about the science behind vaccines.
How a DNA ‘Parasite’ May Have Fragmented Our Genes
A novel type of “jumping gene” may explain why the genomes of complex cells aren’t all equally stuffed with noncoding sequences.
Dinosaur Bone Study Reveals That Not All Giants Grew Alike
A survey of prehistoric bones reveals that T. rex and some of its cousins had more than one way to reach enormous sizes. Evolution may have preserved that variation in modern animals too.
Global Microbiome Study Gives New View of Shared Health Risks
The most comprehensive survey of how we share our microbiomes suggests a new way of thinking about the risks of developing some diseases that aren’t usually considered contagious.
Can We Program Our Cells?
By genetically instructing cells to perform tasks that they wouldn’t in nature, synthetic biologists can learn deep secrets about how life works. Steven Strogatz discusses the potential of this young field with researcher Michael Elowitz.
