Neonicotinoids are partial contraceptives for male honeybees
Male honeybees produce less living sperm if raised on pollen tainted with neonicotinoids, tests show.
- Oceans
Sea ice algae drive the Arctic food web
Even organisms that don’t depend on sea ice depend on sea ice algae, a new study finds. But Arctic sea ice is disappearing.
- Genetics
Dolly the Sheep’s cloned sisters aging gracefully
Cloning doesn’t cause premature aging in sheep.

- Animals
New books deliver double dose of venomous animal facts
In Venomous and The Sting of the Wild, researchers delve into the world of venomous creatures and the scientists who study them.

Yeasts hide in many lichen partnerships
Yeasts newly discovered in common lichens challenge more than a century of thinking about what defines the lichen symbiosis.

Getting rid of snails is effective at stopping snail fever
For the tropical disease snail fever, managing host populations is more effective than drugs.
