Detecting microalgae in coastal waters

...s of algae. "Knowledge is power. We hope this instrument will characterize microalgal populations rapidly and easily, for instance for pre-screening samples for the potentially-harmful types during a red tide," said Dr. MacIntyre. "This fluorometer could be of enormous use for those who monitor our waters...

Climate experts search for answers in the oceans

... Tropical Rainfall Measuring Mission and the AMSRE instrument onboard NASA's Aqua. "Over the last five years there has been a concerted effort by the world space agencies to share and develop satellite ocean temperature measurements together for the benefit of all, and we can expect improvements in operatio...

A new approach to growing heart muscle

...l, Birla explains. It's made possible by a precise instrument called an optical force transducer that gives more precise readings than that used by other teams. The measurement showed that the BEHM that had formed in just four days after a million cells were layered on fibrin gel could contract with an activ...

Selecting life: Scientists find new way to search for origin of life

...ht Secondary Ion Mass Spectrometry (ToF-SIMS). The instrument effectively blasts a sample with ionized particles and fragments the surface-bound molecules and topmost mineral layer. The mass spectrometer allows the researchers to determine what's there. "ToF-SIMS will also allow us to detect the organic molecul...

NHGRI aims to make DNA sequencing faster, more cost effective

Record ozone loss during 2006 over South Pole

...y ?will include a next-generation ozone-monitoring instrument called GOME-2, intended to guarantee continuity of observation of this vital environmental factor well into the following decades. "Long-term measurements of ozone levels are of key importance for being able to monitor the ozone's predicted recove...

New fMRI technology making brain tumor surgery safer

...ed a small electrical stimulation with a wand-like instrument during surgery. If a motor area is stimulated, for example, the patient’s hand will move. Electrical stimulation has had drawbacks, however. “Stimulating the brain with an electrode can cause a seizure,?Dr. McPherson said. “And to accurately ide...

Satellites shed light on global warming

Tears reveal some of their deepest secrets to researchers

...c droplets of the oily substance, which allows the instrument to detect different components based on electrical charges and mass. Nichols points out that researchers have used other techniques, such as chromatography, to characterize types of lipids in the tear film, but advances in mass spectrometry techno...

No-scalpel vasectomies by skilled surgeons may speed recovery

...an incision, the no-scalpel technique uses a sharp instrument to puncture the skin. Advantages of puncturing rather than cutting the skin of the scrotum include less bleeding, bruising, infection and pain. Also, the puncture is usually so small that it does not require stitches. The review looked at two stu...

Map predicting spread of avian flu

...disease between farms. "The risk map concept is an instrument suitable for analyses of epidemic control options both during crisis and in peacetime" says Boender. ...

Surgeons develop simpler way to cure atrial fibrillation

...her cardiac surgery." The device is a clamplike instrument that heats heart tissue using radiofrequency energy. By holding areas of the heart within the jaws of the device, surgeons can create lines of ablation, or scar tissue, on the heart muscle. In the older Cox-maze III procedure, the lines of ablation w...

New technique will produce a better chromosome map

...pe involve using a thumb, pencil, forceps or other instrument to maneuver and press the cells between a glass coverslip and slide. Only about 10 percent of the slides processed this way provide useable images and even those rarely offer crisp structural details, Novikov said. The new approach includes two co...

Envisat captures first image of Sargassum from space

...etected from space for the first time thanks to an instrument aboard ESA’s environmental satellite, Envisat. The ability to monitor Sargassum globally will allow researchers to understand better the primary productivity of the ocean and better predict climate change. Using optical radiance data from the Medi...
