We measure our economies in terms of trade, production and services - but one vital component is missing: the environment. Pavan Sukhdev is the study leader for a UN-run program on the economics of ecosystems and biodiversity, and he wants to see these resources accounted for. Kerri Smith talks to him.

19 November: Why paleontologists should predict instead of just describe, how to factor environmental goods into the economy, the cultural context of Darwin's theories and a round-up of other highlights from Nature.

12 November: How a language gene behaves in humans and chimps, determining orbiting planets from a star's lithium levels, the run up to the UN climate change conference in Copenhagen, and a round-up of what's hot elsewhere in Nature.

5 November: Scientists take a closer look at a star first spotted in 1680, how unrelated animals lend a helping hand, a 'Pleistocene Park' in the Netherlands, and a round-up of what's hot elsewhere in Nature.

29 October: A new type of communication between brain cells is confirmed, a theory about how the Earth became watery, questioning whether the speed of light is constant, and a round-up of what's hot elsewhere in Nature.

22 October: The effects of sleep deprivation on memory, 250 years of London's Kew Gardens, watching evolution in the lab, and climate change in the Himalayas.

15 October: Video game-playing mice, illiterate Columbian guerrillas, a magnet with only one pole, Nobel Prize-winner Elizabeth Blackburn, and in the news - a CERN scientist is charged with being a terrorist.

1 October: Sex chromosome evolution in stickleback and humans, cheat-resisting amoebae, and how powerful earthquakes may influence the strength of far-away faults.

A seismic survey cruise led by the Universities of Oregon and Washington has navigated past objections from Canadian save the whales groups. The researchers just returned to port after a month at sea with new data on a volcanic ridge off the coast. Correspondent Tom Banse reports on what they found.

24 September: Planetary boundaries that are not to be crossed, early humans and carbon dioxide levels, India's genetic diversity, the genomes behind an epidemic.

17 September: Gene therapy to correct colour blindness, droplets behaving weirdly, how warm temperatures in the past affected Greenland, and the evolution of sex chromosomes and live birth.

10 September: The genome behind the Irish potato famine, a new take on the Great Oxidation Event, how dying cells signal 'come-kill-me', and the week's news highlights.

3 September: The galaxy that eats others for breakfast, the oldest hand-axes in Europe, engineering our climate, and predicting 'tipping points'.

27 August: Gene therapy for mitochondrial mutations, a 'hot jupiter' spinning perilously close to its sun, science-themed songs for kids, toxicity testing, and a chance to win tickets to a private screening of the film Creation.
