New nanocatalyst yields more accurate PSA test

Scientists have developed a new catalyst that could make lab tests like the PSA much more sensitive. And it may even speed up reactions that neutralize toxic industrial chemicals before they enter lakes and streams.

Doubt cast on recent study claiming to have unraveled the last mystery of electromagnetism

A group of scientists called into question the results of a study where British scientists claimed that they managed to find the missing link in the electromagnetic theory.

Silica nanoparticles could be used to repair damaged teeth

Researchers have shown how the development of coated silica nanoparticles could be used in restorative treatment of sensitive teeth and preventing the onset of tooth decay.

Atomic resolution images finally explain how platinum catalysts work

Scientists have figured out how a platinum catalyst works - its remarkable properties are not just due to the platinum, the iron-oxide substrate beneath also plays a role.

A glimpse into the nanoworld of lymphocyte cell membranes

Researchers have applied super-resolution methods to study the organization of receptors on B lymphocytesAntigen receptors on B lymphocytes sense foreign molecules, such as pathogens or vaccines, and activate the B cells to produce antibodies that protect humans against many diseases.
