Fruit bats can eat up to twice their body weight in fruit a day. But their genes and cells evolved to process all that sugar without any health consequences − a feat drug developers can learn from.
Rather than a tracking tag telling scientists where this shark traveled, its violent removal let them observe an unexpected regeneration process.

After scientists’ GPS tracking tag was violently removed from one shark’s dorsal fin, they were in for a surprise: The wound didn’t just heal, but the missing tissue grew back.
The adaptations that polar bears will have to make to meet the challenges brought about by climate change are numerous and unpredictable.

Researchers have made a fascinating observation: a polar bear used a diving hunting technique, never before reported, to capture large moulting snow geese.
Most teens aren’t getting enough sleep, leading to poorer academic performance. Early school start times combined with natural changes in hormones and the circadian rhythm could be to blame.
The movement patterns in sperm could be explained by maths often used to describe the way chemicals interact.
The majestic St. Lawrence River, a jewel of economic, historical and environmental importance, reminds us of the need to preserve this essential ecosystem.

The waters of the St. Lawrence are running out of breath and bottom-dwelling organisms are already feeling the effects. Here’s how ecosystems are reacting.
Temperature sensitivity makes western fence lizards vulnerable to climate change.

From dark dragonflies becoming paler to plants flowering earlier, some species are slowly evolving with the climate. Evolutionary biologists explain why few will evolve fast enough.
The glamourous aspect of fashion obscures the health and socio-environmental issues of the textile industry.

Spanning evolutionary biology, genetics, development, neurobiology, endocrinology and psychology, as well as current events and sports, students explore the complexities of the biology of sex.
Rocky Mountain fires leave telltale ash layers in nearby lakes like this one.

As the climate warms, devastating fires are increasingly likely. The 2020 fires pushed the Southern Rockies beyond the historical average. Is there hope for the Northern Rockies?
Box jellyfish have no brains, yet were recently found to be able to learn from touch. Many brainless organisms are now forcing us to rethink what it means to learn.
Storytelling can be an effective way to impart lessons in science.
