Researchers put safety of 'magic anti-cancer bullet' to test
Researchers have carried out the first systematic study analyzing the safety of so-called upconversion nanoparticles that may be used to treat skin cancer and other skin diseases. This study is one of the most important steps on the path to new, safe and effective methods to diagnose and treat cancer.

Read moreSea sponge anchors are natural models of strength
Life may seem precarious for the sea sponge known as Venus' flower basket. Tiny, hair-like appendages made essentially of glass are all that hold the creatures to their seafloor homes. But fear not for these creatures of the deep. Those tiny lifelines, called basalia spicules, are fine-tuned for strength.

Read moreEngineers invent two-dimensional liquid
Where water and oil meet, a two-dimensional world exists. This interface presents a potentially useful set of properties for chemists and engineers, but getting anything more complex than a soap molecule to stay there and behave predictably remains a challenge. Now, researchers have hown how to do just that. Their 'soft' nanoparticles stick to the plane where oil and water meet, but do not stick to one another.
