The movement patterns in sperm could be explained by maths often used to describe the way chemicals interact.
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.
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 production, use and end-of-life of clothing all have an impact on our health. But greater ecological awareness could turn the tide.
‘Assembly theory’ aims to explain evolution without biology. Is it a dazzling breakthrough or an attempt to answer questions nobody asked?
Understanding how the intricate spots and stripes, or Turing patterns, of many animals form can help scientists mimic those processes in the lab.
‘Living materials’ made with genetically engineered bacteria and Jell-O-like gel could make pollutants in water bodies nontoxic.
246 scientists looked at the same data sets and drew very different conclusions.
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.
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.
Poetry and prose are prominent features in this course about how climate change is affecting the world.
Pigs with human kidneys? Brain-powered computer chips? Science is creating new kinds of living things – and our moral understanding needs to catch up fast.
The results are intriguing, but analysing the atmospheres of exoplanets is no easy task.
We may have become the most complex living creature in part by accident and replication of error.
Tracing isotopes of carbon inside amino acid molecules has revealed the ‘metabolic fingerprints’ of how different animals store and use energy.
Flies often beat out competitors for food because of their specialized sensing organs called antennae.
‘Don’t Say Gay’ bills claim to use science to justify a binary definition of sex based on certain traits. But the biology of sex and gender is not so simple.
Stem cells could help regenerate diseased or damaged parts of the body – but first, scientists need to make the cells forget their own histories.
Humans have been making symbols for numbers for thousands of years. Different cultures developed their own symbols, but all use addition and multiplication, suggesting arithmetic is a universal truth.
