Super-slow circulation allowed world’s oceans to store huge amounts of carbon during the last ice age

27 Jun 2016

The way the ocean transported heat, nutrients and carbon dioxide at the peak of the last ice age, about 20,000 years ago, is significantly different than what has previously been suggested, according to two new studies. The findings suggest that the colder ocean circulated at a very slow rate, which enabled it to store much more carbon for much longer than the modern ocean.

Birds evolve ‘signature’ patterns to distinguish cuckoo eggs from their own

Using new ‘pattern recognition algorithm,’ latest research highlights how birds are ‘fighting back’ against the parasitic Common Cuckoo in what scientists describe as an evolutionary ‘arms race’. They found that birds with the most sophisticated and distinctive egg patterning are those most intensely targeted by the cuckoo’s egg mimicry.
