Some 500 million years ago—when our continents were likely connected in a single land mass and most life existed underwater—hornworts were one of the first groups of plants to colonize land. But biologists have never understood much about the...
Genetically modified (GM) Bt cotton produces its own insecticide. The seeds were introduced in India in 2002 and today account for 90% of all cotton planting in the country. Bt cotton is now the most widely planted GM crop...

New research shows that crustaceans such as shrimps, lobsters and crabs have more in common with their insect relatives than previously thought—when it comes to the structure of their brains.
Both insects and crustaceans possess mushroom-shaped brain structures known in insects to...
Pollination by bees is vital even when crops are assumed to be pollinator independent. That's according to a study co-authored by Ethel Villalobos, a researcher in the University of Hawaii at Manoa's College of Tropical Agriculture and Human Resources...
Fish school by copying each other and changing directions randomly, rather than calculating and adapting to an average direction of the group, a group of scientists co-led by UNSW has shown.
In a study published today in Nature Physics, an international...
Taking a cat to the vets can be a stressful experience, both for cat and owner. However, a study published in this month's issue of the Journal of Feline Medicine and Surgery (JFMS) has shown that playing cat-specific music during the...
Seagulls favour food that has been handled by humans, new research shows.
Herring gulls were presented with two identical food items—one of which they had seen a human holding.
The gulls pecked more often at the handled food, suggesting they use...
Some species of deaf moths can absorb as much as 85 per cent of the incoming sound energy from predatory bats—who use echolocation to detect them. The findings, published in the Journal of the Royal Society Interface today, reveal the moths,...
