Elephant seals monitor ocean health

Diving almost continuously at great depth during most of the year, and covering large distance through remote areas of the Southern Ocean, Kerguelen elephant seals have proved to be a great alternative to other instruments for monitoring the oceans. The seal-derived measurements of oceanic dissolved oxygen give better results than other methods, according to new research.

Global temperature rise

Contrary to recent reports that there has been a hiatus in global warming, with improvements in measurements scientists conclude that the rate of warming over the first 15 years of this century has, in fact, been as fast or faster than that seen over the last half of the 20th century. 2014 was the hottest year on record.

Scientists develop mesh that captures oil but lets water through and could help clean oil spills. The work was partly inspired by lotus leaves, whose bumpy surfaces naturally repel water but not oil.
