A new way to generate electricity from sewage uses naturally occurring “wired microbes” as mini power plants to produce electricity as they digest plant and animal waste.
Birds split from dinosaurs when their front limbs got longer and their back limbs got shorter, according to new research.
An enzyme that “unravels” DNA appears to trigger male development of the embryo, a finding that may give greater insight into intersex disorders.
Nerve circuits let the brain turn down sounds that come from our own actions, and turn up other sounds we need to pay attention to, say researchers.
Chemists are hopeful their new energy-efficient method to desalinate water can be scaled up for personal or even municipal uses
As climate change forces birds in Tanzania to head west, protected areas set aside for mammals are keeping them alive.
Engineers trying to mimic the peacocks’ color mechanism for screens have locked in structural color, which is made with texture rather than chemicals.
High temperatures and low rainfall brought on by climate change affect the survival of elephants working in timber camps in Myanmar and double the risk of death to the calves.

An environment that shifted between open grassland and closed woodland in East Africa roughly 2 million years ago may be responsible for driving human evolution.
Working with fossils found in Tanzania, scientists have discovered what may be the oldest known dinosaur.
Homicide moves through a community like an infectious disease, a finding that may help police track and even prevent murders.
They may not go out and buy a shiny sports car, but chimpanzees and orangutans can experience a mid-life crisis, just like humans.
China’s endangered wild pandas need bamboo to survive, but models show that climate change may kill it off in swaths.
People’s satisfaction with life was higher on days when they exercised more than usual, research shows.
