The Hidden Brain Connections Between Our Hands and Tongues
Sticking out your tongue while doing delicate work with your hands reveals a history of evolutionary relationships.
Selfish, Virus-Like DNA Can Carry Genes Between Species
Genetic elements called Mavericks that have some viral features could be responsible for the large-scale smuggling of DNA between species.
What Can Jellyfish Teach Us About Fluid Dynamics?
Jellyfish and other aquatic creatures embody solutions to diverse problems in engineering, medicine and mathematics. John Dabiri, a fluid dynamics expert, talks with Steven Strogatz about what jellyfish can teach us about going with the flow.
The Key to Species Diversity May Be in Their Similarities
New modeling work suggests why nature is more diverse than niche-based ecological theory predicts.
How 3D Changes in the Genome Turned Sharks Into Skates
Changes in the 3D structure of their genome gave skates and rays their distinctive winglike fins and pancake flatness.
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.
Simpler Math Predicts How Close Ecosystems Are to Collapse
By replacing thousands of equations with just one, ecology modelers can more accurately assess how close fragile environments are to a disastrous “tipping point.”
