Odd properties of water and ice explained: Water exists as two different liquids

Scientists have discovered two phases of liquid water with large differences in structure and density. The results are based on experimental studies using X-rays.

Could this strategy bring high-speed communications to the deep sea?

A new strategy for sending acoustic waves through water could potentially open up the world of high-speed communications to divers, marine research vessels, remote ocean monitors, deep sea robots, and submarines. By taking advantage of the dynamic rotation generated as the acoustic wave travels, also known as its orbital angular momentum, researchers were able to pack more channels onto a single frequency, effectively increasing the amount of information capable of being transmitted.

Collapse of European ice sheet caused chaos in past

Scientists have reconstructed in detail the collapse of the Eurasian ice sheet at the end of the last ice age. The big melt wreaked havoc across the European continent, driving home the original Brexit 10,000 years ago.

Why dogs all over the world owe this 'ugly' dog a debt

Martha, this year's winner of the World's Ugliest Dog contest, has a powerful message for dog-kind everywhere.

New research could help humans see what nature hides

Things are not always as they appear. New visual perception research explains the natural limits of what humans can see and how to find what nature hides.

Animals, not drought, shaped our ancestors’ environment

The expansion of grasslands isn't solely due to drought, but more complex climate factors are at work, both for modern Africans now and ancient Africans in the Pleistocene, suggests new research.

Brains evolved to need exercise

Mounting scientific evidence shows that exercise is good not only for our bodies, but for our brains. Yet, exactly why physical activity benefits the brain is not well understood. Researchers suggest that the link between exercise and the brain is a product of our evolutionary history and our past as hunter-gatherers.

Where are the new therapies for heart disease?

Early antiretroviral therapy linked with bone loss in patients with HIV

Current HIV treatment guidelines now recommend initiating antiretroviral treatment (ART) at the time of diagnosis. However, a new study has found that such early ART causes greater bone loss compared with deferring ART.
