Saving kelp forests and our climatethe kelp forests fringing the North Pacific coast are one of the richest marine ecosystems On earth.

Kelp beds buffer coastlines from storms and sequester carbon as effectively as tropical rainforests. One of the kelp forest's most endearing denizens, the sea otter, is an important key to its survival.

In some places this valuable kelp carbon store is mown disappearing down by a hungry army of sea urchins.

We tend to think that we can deal with the challenge of carbon dioxide in the atmosphere by planting more vegetation,

In 1978, psychologists David Premack and Guy Woodruff wondered if chimpanzees have theory of mind.

they preferred cotton previously used by other mice to unused cotton for nest-building. Perhaps most surprising the mice even preferred parasitised cotton balls to clean ones.

These preferences also applied to their foraging behaviour. The mice were no less likely to eat seeds that were found near faecal material oe

Neither animal could distinguish parasitised from healthy droppings yet sheep responded by playing it safe,

Reeds were seeded then across the site to dry out the new land before they were replaced by rapeseed,

the design team Koetter Kim suggested cooling towers could be replaced by recirculating water through green space such as wetlands, walls of vegetation, agriculture and fountains.

This means there is less opportunity for the leaves to leak water oe C3 plants lose 97%of the water they take up through their roots to transpiration.

There are no more infertile stretches of asphalt sprawled over our urban rooftops but an expanse of vegetation

The practice of biomimicry already taps into nature's ingenuity oe for example, the famous hexagonal skin of Norman Foster's Gherkin was inspired by the Venus Flower Basket sponge,

Think of how trees share common technologies (leaves, trunk, roots) adapted to different kinds of environments

and using a range of resources. For example, needle-leaved Canadian evergreens make the most of scant sunlight

and their leaf litter feeds the acidic soils that nurture networks of microorganisms, such as nitrogen-fixing bacteria,

The self-described health nut who was in training to run marathons suddenly found himself unable to jog for more than a couple of minutes before coming to a gasping, staggering halt.

However, it could equally have been powered by one of a number of biofuels made from algae, flax, coconut husks or even from used cooking-oil.

Most efforts to establish the root of risky decisions made by human teenagers focus on the underdeveloped prefrontal cortex, the part of the brain responsible for mental processes like long-term planning and judgement.

And the relatively featureless landscape doesn't provide much in the way of visual landmarks, other than perhaps the odd rock or weed.

Minutes later, the departed group identifies a temporary resting place on a nearby tree branch, and from there it surveys the local real estate. Several hundred scouts fan out in all directions in search of a suitable location for a new hive.

as we convert vast tracts of wild vegetation to agricultural or grazing areas, for example. Fishing on an industrial scale to provide for billions has altered dramatically marine diversity.

however, inappropriate flooding of vegetation can cause greenhouse gas emissions and poison the water for fish.

These so-called"induced pluripotent stem cells Â (otherwise known as ips cells) are in turn capable of making every cell in the body.

"That made us realize that we had probably the largest repository of potential stem cells,

As a first step, Ryder and a team of stem cell scientists have reprogrammed the skin cells from a northern white rhinoceroses named Fatu, one of seven still alive,

Armed with this code, they then need to find a way of engineering a regular pigeon's stem cells into behaving like a passenger pigeon's stem cells by mutating the genome.

To endow ordinary lab mice with these traits Church will try to partially rewrite the genomes of mouse stem cells.

However, he admits that creating a passenger pigeon from the stem cells of an ordinary pigeon would involve a massive scale up of the same technologies.

Once shrubs and grasses have been cleared from the land there are no roots to hold soil, nutrients and water in place.
