An ancient sexual conflict over mitochondrial inheritance may be responsible for the evolution of the two sexes as we know them.
The short answer is no. But worms can use different parts of their body to do some of the jobs that our tongues do - like tasting and crushing food.
By exploiting the way yeast cells mate, researchers have figured out a quicker, easier way to identify on- and off-target drug interactions.
Younus, age 9, wants to know how people become allergic to food.
A stable environment that teaches men to be men and women to be women could be helping to enforce gender across generations.
His anti-PC 'manifesto' might be filled with nonsense, but that doesn't mean James Damore's thoughts have no value, or that he should have been fired.
We're used to thinking of our eyes detecting light as the foundation of our visual system. But what's going on in other cells throughout the body that can detect light, too?
Simple and inexpensive gene-editing technology such as CRISPR has made the creation of genetically modified organisms much easier. But could nature still keep the upper hand?
How can life on Earth help us understand life in space? To answer this question, we compare biological clocks and geological rocks and find that they tick uniformly.
Researchers identified simple behavioral rules that allow these tiny creatures to collaboratively build elaborate structures, with no one in charge.
Today algorithms are ubiquitous, yet often misunderstood. Rather than mysterious entities, they're closer to recipes, and the quality of the output depends on the input – in their case, data.
A seed contains nearly everything a tree needs to get growing. Just add a dash of water, a bit of warmth and the right location, and you'll be seeing green in no time.
A new research paper reports dangerous side effects in CRISPR-edited mice. Some scientists are pushing back, placing blame for the unwanted mutations on the experiment, not the technique.
Biologists have a centuries-old tradition of publishing on rare and endangered species. But poachers are using open-access information to target valuable and fragile new species.
New research reveals how flamingos can stand – and even sleep – on one leg for so long.
These birds spend long periods, often asleep, standing on one leg. Is it passive biomechanics or active nervous system control of their muscles that allows them to do easily what's impossible for us?
Researchers are starting to harness the potential of this much-hyped gene editing technique – with coming applications in medicine, biology and agriculture.
Bio-prospecting is the search for useful materials from natural sources. A biologist explains what we can learn from bacteria about breaking down plant material, and how we can use that knowledge.
Scientists invented chemical weapons; some are now working to destroy them. New biomolecular design techniques let researchers design proteins that can destroy nerve agents in bodies.
Taking the placenta as a case study, researchers are able to piece together how new organs evolve, by repurposing old tissues and using them to do new jobs.
