With the help of directed evolution, scientists inch closer to developing viral vectors that can cross the human blood-brain barrier to deliver gene therapy.

Many species of birds and other vertebrates form pair bonds and mate with just one other individual for much of their lives. But the unions don’t always work out. Scientists want to know the underlying factors.

George Church is at it again, this time using multiplex gene editing to create virus-proof cells, improve organ transplant success, and protect elephants.

Across the animal kingdom, dominance isn’t the only way for a male to score. Colluding, sneaking around, or cross-dressing can work, too.

A high-quality genome sequence for this versatile insect will likely aid eco-evolutionary research.

The researchers who constructed the first reference genome for this critically endangered mollusk say it will assist restoration efforts.

Evidence from various sciences reveals that there are diverse ways of being male, female, or both. An anthropologist argues that embracing these truths will help humans flourish.

Studies have found that organisms can inherit mitochondria from male parents in rare instances, and both theoretical and experimental work hint that this biparental inheritance is more than just a fluke.

A round-up of recent discoveries in behavior research

Researchers aim to unravel the molecular mechanisms by which a single genotype gives rise to diverse castes in eusocial organisms.
