Turning down the heat on thin films.

Superconducting thin films will be essential to any practical application of superconductivity to microelectronics. Scientists have now succeeded in putting these thin films onto silicon, which is the base element in most integrated circuits.

A technique for catheterization of the equine antebrachiocarpal joint.

A 2.5-cm long, 0.8 mm in diameter catheter was placed percutaneously into the palmarolateral pouch of the antebrachiocarpal joint in 6 clinically normal horses.

Effect of gentamicin sulfate and sodium bicarbonate on the synovium of clinically normal equine antebrachiocarpal joints.

The effect of gentamicin sulfate, unbuffered and buffered with sodium bicarbonate, on synovial fluid and membrane of clinically normal equine joints was evaluated. Thirty-six adult horses with clinically normal antebrachiocarpal joints were allotted to 6 treatment groups of 6 horses each. One antebrachiocarpal joint in each horse was chosen for treatment.

Advances in measurement science.

Year after year, physicists measure various quantities with increasing accuracy and see various objects in increasing detail. These advances are vital, because science's understanding of the physical world is necessarily limited by the accuracy with which science can measure that world. The Instrument and Measurement Science Topical Group of the American Physical Society sponsored several symposia at the recent APS March meeting in New Orleans that discussed recent advances in measurement and observation.
