The world’s first clinical trial to compare three ways of delivering insulin to control glucose levels in patients with type 1 diabetes concludes that two versions of an artificial pancreas do a better job than conventional pump therapy. The results could have significant implications for the treatment of type 1 diabetes. Read more

The extent of sea ice cover in Arctic was much less than it is today between four and five million years ago. The maximum winter extent did not reaching its current location until around 2.6 million years ago. “We have not seen an ice free period in the Arctic Ocean for 2,6 million years. However, we may see it in our lifetime.” says a marine geologist.

Car finish, to which no dirt particles adhere, house fronts, from which graffiti paints roll off, and shoes that remain clean on muddy paths – the material “fluoropore” might make all this possible. Both water and oil droplets roll off this new class of highly fluorinated super-repellent polymers.

Mate choice is often the most important decision in the lives of humans and animals. Scientists have found the first evidence that birds may choose their mate through odor. The researchers compared the preen gland chemicals of black-legged kittiwakes with genes that play a role in immunity. Kittiwakes that smell similarly to each other also have similar genes for immunity. Since the birds prefer to mate with unrelated mates, the scientists have now found the likely mechanism by which they recognize relatedness.
