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.
A Mutation Turned Ants Into Parasites in One Generation
A new genetics study of ant “social parasites” shows how complex sets of features can emerge rapidly and potentially split species.
Ants Live 10 Times Longer by Altering Their Insulin Responses
Queen ants live far longer than genetically identical workers. Researchers are learning what their longevity secrets could mean for aging in other species.
A Biochemist’s View of Life’s Origin Reframes Cancer and Aging
The biochemist Nick Lane thinks life first evolved in hydrothermal vents where precursors of metabolism appeared before genetic information. His ideas could lead us to think differently about aging and cancer.
Protein Blobs Linked to Alzheimer’s Affect Aging in All Cells
Protein buildups like those seen around neurons in Alzheimer’s, Parkinson’s and other brain diseases occur in all aging cells, a new study suggests. Learning their significance may reveal new strategies for treating age-related diseases.
Brain-Signal Proteins Evolved Before Animals Did
Some animal neuropeptides have been around longer than nervous systems.
Secrets of Early Animal Evolution Revealed by Chromosome ‘Tectonics’
Large blocks of genes conserved through hundreds of millions of years of evolution hint at how the first animal chromosomes came to be.
Flying Fish and Aquarium Pets Yield Secrets of Evolution
New studies reveal the ancient, shared genetic “grammar” underpinning the diverse evolution of fish fins and tetrapod limbs.
Sponge Genes Hint at the Origins of Neurons and Other Cells
A new study of gene expression in sponges reveals the complex diversity of their cells as well as some possibly ancient connections between the nervous, immune and digestive systems.
