- 1. Change of tune for Hawaiian crickets?
Crickets that lost their song in an evolutionary bid to escape predators could hold the key to understanding how bursts of new species can form so quickly.
- 2. Genetic toolkit gives periwinkles seashore advantage
Periwinkles, struggling to survive the seashore battleground, have developed a genetic toolkit to help them adapt to different environments, a new study shows.
- 3. Down in the bottom of the deep blue sea
Deep sea covers most of our planet and yet we know more about the surface of the moon than its dark depths.
- 4. Devil rays get worldwide protection, and genetic tools could catch out illegal traders
Devil rays, close cousins of the enormous manta rays, are stars of nature documentaries. These charismatic creatures are under threat from humans, specifically, because of the gill plate trade.
- 5. Bug brother is watching you
Scientists have spent several years filming a field of crickets in Spain with more than 140 digital video cameras to find out more about what makes them tick.
- 6. The failure of genomics
Biology is in the grip of a genomics revolution - but Mark Viney thinks this may have taken a wrong turn. He says that just DNA sequencing genes isn't enough - we need to get back to finding out what each one does.
- 7. The future of tree health
Ancient mainstays of our woodlands, hedgerows and parklands are at risk from a surge of pests and diseases - but a new research programme is bringing experts together from many fields to find solutions.
- 8. From the age of the dinosaurs?
The term 'living fossil' was coined by Darwin and has since been applied to various species that appear not to have changed for millions of years. But when Africa Gómez and colleagues took a closer look at tadpole shrimps they concluded we should ditch the term for good.
- 9. Podcast: The evolution of the British peppered moth
This week in the Planet Earth podcast, Ilik Saccheri and Arjen van 't Hof of the University of Liverpool describe how the British peppered moth changed from peppered to black during the Industrial Revolution in northern England.
- 10. Genetically engineered flies could save fruit crops
Fruit crops ravaged by the Mediterranean fruit fly could be saved by genetic engineering, say scientists who have altered the genes of some male flies so they can only produce sons.
