NASA study finds snow melt causes large ocean plant blooms

...evaporation of wet soil. As a result the land mass heats up more in summer creating a larger temperature difference between the water of the Arabian Sea and the Indian subcontinent landmass. The temperature difference is responsible for a disparity in pressure over land and sea, creating a low pressure sy...

Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer

...late in the tumor; the addition of NIR laser light heats up their gold shell, causing the particles to destroy tumor cells. Furthermore, because of their size − a few nanometers, or billionths of a meter, in diameter − these nanoshells interact with light in specific ways, and can be "tuned" to...

Deep-rooted plants have much greater impact on climate than experts thought

...azon." This effect changes the way the atmosphere heats and cools, and will change the way rain is distributed, he noted. Depending on the extent to which trees elsewhere in the world, especially in Africa and other tropical and extratropical areas, redistribute water in the soil, the impact on global cli...

Combined treatment extends life expectancy for lung cancer patients

...nvironment. Thermal ablation, on the other hand, heats the tumor to kill cancerous cells ?reaching the center of the tumor, but not necessarily killing all the cells at the edges. This can lead to a recurrence of the tumor, and the cancer may spread. Thermal ablation is delivered directly to cancerous ce...

Gold nanoparticles prove to be hot stuff

... scientists also found that gold absorbs light and heats up quickly, by a remarkable 266 degrees (Celsius) per watt of laser power, at the wavelength most often used in optical traps. Unless very low laser power is used, the heat could damage the molecules under study. Thus, gold beads would not be useful ...

U of M researchers invent 'flashy' new process to turn soy oil, glucose into hydrogen

...ted a "reactive flash volatilization process" that heats oil and sugar about a million times faster than yo...aturated solution of glucose in water, the process heats the sugar so fast that it, too, breaks up into syngas instead of its usual products: carbon and wate...

Surgeons develop simpler way to cure atrial fibrillation

...ery." 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 were made by...

Genome sequencing reveals key to viable ethanol production

...s the national push for alternative energy sources heats up, researchers at the University of Rochester have for the first time identified how genes responsible for biomass breakdown are turned on in a microorganism that produces valuable ethanol from materials like grass and cornstalks. Waste products su...
