Soundproofing with quantum physics
Scientists have shown that the road from abstract theory to practical applications needn't always be very long. Their mechanical implementation of a quantum mechanical phenomenon could soon be used for soundproofing purposes.

Why the seahorse's tail is square
Why is the seahorse's tail square? An international team of researchers has found the answer and it could lead to building better robots and medical devices. In a nutshell, a tail made of square, overlapping segments makes for better armor than a cylindrical tail. It's also better at gripping and grasping.

The sting in dengue's tail
Scientists have identified how small changes in dengue's viral genome can affect the virus' ability to manipulate human immune defenses and spread more efficiently.

Ridges and valleys: Experiments open window on landscape formation
Geologists have seen ridges and valleys form in real time and -- even though the work was a fast-forwarded operation done in a laboratory setting -- they now have an idea of how climate change may impact landscapes.

Novel HIV vaccine regimen provides robust protection in non-human primates
A new study shows than an HIV-1 vaccine regimen, involving a viral vector boosted with a purified envelope protein, provided complete protection in half of the vaccinated non-human primates (NHPs) against a series of six repeated challenges with simian immunodeficiency virus (SIV), a virus similar to HIV that infects NHPs.

Vaccines and treatment for dengue virus possible
Researchers have determined the structure of a human monoclonal antibody which, in an animal model, strongly neutralizes a type of the potentially lethal dengue virus.

Do you really think you're a foodie?
Think you're a foodie? Adventurous eaters, known as 'foodies,' are often associated with indulgence and excess. However, a new study shows just the opposite -- adventurous eaters weigh less and may be healthier than their less-adventurous counterparts.

Long-term memories are maintained by prion-like proteins
Researchers have uncovered further evidence of a system in the brain that persistently maintains memories for long periods of time.

Telomeres linked to origins of idiopathic pulmonary fibrosis
Researchers have now discovered that telomeres, the structures that protect the chromosomes, are at the origin of pulmonary fibrosis. This is the first time that telomere damage has been identified as a cause of the disease. This finding opens up new avenues for the development of therapies to treat a disease for which there is currently no treatment.
