Latest on your blood

The high level of profits from medical research and the possibilities of new sciences and technologies stretch our imagination, here in the office, at least. Now a distant and very ancient ancestor has very obviously given us, through simple breeding, a wonderful solution to survival at altitude. Who knows how climbers or even space travellers could benefit as we use our new knowledge?

Foxy moves for successful species

Foxy moves for successful species

Posted Wed, 11 Jun 2014 08:37:43 GMT by Colin Ricketts

What a turn up for the book. The Arctic fox didn't evolve from Eurasian or North American relatives. Instead, the climates of the Himalaya and Arctic were at one time similar enough to encourage migration in several animals. This species of fox must now be counted as related to an extinct animal that adapted thousands of kilometres away to mountainous terrain that resembles its present niche.

Finding sheep 'geneius' in their genome

Finding sheep 'geneius' in their genome

Posted Fri, 06 Jun 2014 06:28:01 GMT by Dave Armstrong

What can we make of the revelations on how species are really related to each other - or not? Big business will certainly cash in on the wool or any wool substitute alternative, just as spider silk is building into a stiff competitor. We all benefit from the science that informs, with Open wherever possible, and creates almost automatic advances in our culture. The sheep has been with us from the beginning of settlements and still looks likely to give us information on how we have eaten and kept warm and how domestic animals have changed, not always for our convenience.

Saving bees with new pesticide

Saving bees with new pesticide

The need for a pesticide for farmers and others that excludes pollinators and other useful insects from its action is desperate. We prefer not to kill any non-pest. But the loss of potentially all our bees is a risk that only chemical companies have been willing to take.

How relevant is research for our everyday lives, the answer is not at all in this case, but the potential is so great we had to bring this to your attention.

The abyss and the intertidal zone share ecological characteristics with all known marine ecosystems. They simply use their abundant animas as providers of shelter and many other functions. Rare species have a lesser role within the community.

Personality in great tits stretches as far as deciding whether to risk your life for your eggs. Would you go back home if somebody seems to threaten your cosy little nest in some unknown way? Insights into survival, evolution of boldness, domesticity and even our own reactions to stress can be found here!

The 3-fingered or 3-toed sloth can finally breathe a sloth sigh of relief. We've finally found out how it manages to breathe upside down. To be honest, we’d never thought there was a problem, but there is.

This little sea-bream is able to conveniently dispose of and control jellyfish populations, just as the big turtles can. The research involved has a lot of relevance to turtle conservation as well as the massive jellyfish blooms reported in Japan and other parts of the world.

Leatherback logging in the Atlantic

The study of marine turtles is linked with tagging of many other animals, but if we lose these leatherback giants of the seas, we will have lost a species that can relay how conditions millions of years ago influenced even bigger turtles and of course every other species that existed at the time.

Swimming sloths with aquatic adaptations

Swimming sloths with aquatic adaptations

Posted Wed, 12 Mar 2014 07:17:00 GMT by JW Dowey

One group of sloths made the quite unlikely shift to water, possibly because of a drying environment in the Miocene. This clever paper shows how they coped with a marine life, just like early whales, by adapting their bone compactness. Our pygmy sloths on the Panamanian island of Isla Escudo de Veraguas are the most recent speciation, around 9,000 years ago. These guys were several species on a sea trip!

Animals of unfamiliar as well as familiar types took up niches in the ancient ecosystems, as birds and mammals developed and, of course, feathered dinosaurs ruled the roost!

We can't find the fossils and the genome can give only some hints. How did the first human-like species survive and why did they have to be black. Mel Greaves has the answers.
