Tracking down smallest biomarkers

Microvesicles are smallest cell elements which are present in all body fluids and are different, depending on whether a person is healthy or sick. This could contribute to detecting numerous diseases, such as, e.g., carcinomas, at an early stage, and to treating them more efficiently. The problem is that the diameter of the relevant microvesicles generally lies below 100 nm, which makes them technically detectable, but their exact size and concentration hardly possible to determine.

Graphene/nanotube hybrid makes single-surface material for energy storage, electronics

A seamless graphene/nanotube hybrid may be the best electrode interface material possible for many energy storage and electronics applications.

Researchers use shock tube for insight into physics early in blasts

Researchers are using a unique multiphase shock tube to study how densely clustered particles disperse during an explosion.

Unexpected data from the Large Hadron Collider suggest the collisions may be producing a new type of matter

Collisions between protons and lead ions at the Large Hadron Collider (LHC) have produced surprising behavior in some of the particles created by the collisions. The new observation suggests the collisions may have produced a new type of matter known as color-glass condensate.

New methods for ion cooling

Among the most important techniques developed in atomic physics over the past few years are methods that enable the storage and cooling of atoms and ions at temperatures just above absolute zero. Scientists from Bangalore and Mainz have now demonstrated in an experiment that captured ions can also be cooled through contact with cold atoms and may thus be stored in so-called ion traps in a stable condition for longer periods of time. This finding runs counter to predictions that ions would actually be heated through collisions with atoms.
