'Good vibrations' from deep-sea smokers may keep fish out of hot water

...sts would like to understand better. Commonly used instruments to measure flow are often short lived when inserted in the superheated, corrosive black-smoker fluids. How much simpler if the vents were generating some kind of sound that could be recorded and correlated to flows, Crone says. With funding from two ...

Successful development of prototype assays

... open instrument platforms such as automated ELISA instruments and closed instrument platforms such as clinical chemistry analysers. The assays could also be run in hand held point-of-care (POC) testing devices allowing diagnosis of a broad range of conditions at the bedside. By exploiting panDA Homogeneous ...

Tracking sperm whales and jumbo squid

...periodically sampled the animals depth. Unlike the instruments used on whales, the squid tags were designed to detach at a predetermined time, then float to the surface and transmit stored data to the satellite. Results During the study, electronic tags were placed on five whales and three jumbo squid swim...

New reference material for diagnosing kidney disease

Level 1 (0.75 mg/dL) is within the normal range of serum creatinine levels, while Level 2 (3.92 mg/dL) is intended to corre...

New sensor detects gaseous chemical weapon surrogates in 45 seconds

...vious LPAS measurement methods. Historically, LPAS instruments were physically large, often measuring a meter or more in length. The entire arrangement was cumbersome, power-hungry and prone to interference from external sound and vibration. In the QPAS technique, several QCLs can fit on a 3 x 3 millimeter chi...
