Changes to RNA aid the process of learning and memory

RNA carries pieces of instructions encoded in DNA to coordinate the production of proteins that will carry out the work to be done in a cell. But the process isn't always straightforward. Chemical modifications to DNA or ...

A single genetic switch changes butterfly wing color

Heliconius butterflies are a diverse and colorful group of species that live throughout tropical regions of Central and South America. Many of them have wing patterns and colors that mimic other species to protect themselves ...

The grim, final days of a mother octopus

Octopuses are the undisputed darlings of the science internet, and for good reason. They're incredibly intelligent problem-solvers and devious escape artists with large, complex nervous systems. They have near-magical abilities ...

Elephants resist cancer by waking a zombie gene

An estimated 17 percent of humans worldwide die from cancer, but less than five percent of captive elephants—who also live for about 70 years, and have about 100 times as many potentially cancerous cells as humans—die ...

Birds from different species recognize each other and cooperate

Cooperation among different species of birds is common. Some birds build their nests near those of larger, more aggressive species to deter predators, and flocks of mixed species forage for food and defend territories together ...

Genetic screening tool identifies how the flu infiltrates cells

Researchers at the University of Chicago have developed a genetic screening tool that identified two key factors that allow the influenza virus to infect human lung cells. The technique uses new gene editing tools to create ...
