UCSB scientists probe sea floor venting to gain understanding of early life on Earth

...ermal vents are largely unexplored. The flanks are deeper than the mid-ocean ridge crest. Cooling of the tectonic plates, and the impact of the ridge flank system on the chemistry of the ocean, are fundamental global-scale processes. On dives in the submersible Alvin, Haymon and her UCSB colleagues –?Ken C...

Open microfluidic and nanofluidic systems

...rinks the surface channels and, in this way, moves deeper into the nanoregime. As one reaches a channel width of about 30 nanometer, one theoretically expects new effects arising from the line tension of the contact line, but such nanochannels have not been studied experimentally so far. The new PNAS study...

World's largest rainforest drying experiment completes first phase

...the dry plot, the trees simply absorbed water from deeper in the soil with their extensive root systems, avoiding most of the visible symptoms of drought stress. By the end of the five-year period of exclusion, many trees in the forest were drawing in water from more than 40 feet deep in the soil. Second, ...

Solutions that reduce death of marine life reeled in by International Smart Gear Competition

...ts and release or "set" the baited hooks at depths deeper than 100 meters (328 feet), which allows longline fishermen to minimize encounters with sea turtles while maximizing their tuna catch. Successful testing of this idea has been carried out by three vessels fishing for tuna in Pacific waters. In initia...

NASA study finds snow melt causes large ocean plant blooms

...the Arabian Sea lacks an opening to the north, the deeper waters are not well ventilated. Also when organic matter produced by phytoplankton breaks down and decomposes, more oxygen gets consumed in the process. An increase in phytoplankton could therefore cause oxygen deficiencies in the Arabian Sea to spre...

Study: 'homemade' gene expression technology unreliable

...this is particularly important as scientists delve deeper into the genomes of humans and other animal species in their quest to find cures for a variety of diseases. "Human genome mapping has made the production of these microarrays possible," Spencer said. "Our interest is in how environmental factors ?dr...

...ed by the river organisms." "River breath is much deeper and faster than anyone realized," says Jeff Richey, UW oceanographer and another co-author. Carbon is carried by rains and groundwater into waterways from soils, decomposing woody debris, leaf litter and other organic matter. Once in waterways it is...

Genetic links could unlock clues to leading cause of blindness

According to the National Eye Institute, nearly 2 million Americans have advanced age-related macular degeneration, a disease that develops w...

New tool reveals secrets of migrating cells

...he less energetic, long-wavelength photons will go deeper into the tissue, cause less damage and scatter less, Robey said, essentially illuminating slices through the tissue that can be sharply imaged and stacked to produce a 3-D image of the cells in real time. The system they use employs an infrared laser...

"We're bringing two-photon imaging to endoscopy and we're putting it all into a miniaturized package," says Mark Schnitzer, the team leader on the Optics Letters paper. The Stanford rese...

Bitter or sweet? The same taste bud can tell the difference

That finding gives scientists a deeper understanding of how the human brain may distinguish between different types of tastes, said Scott Herness, the study's lead author and a professor of oral biology and neuroscience at Ohio State University . The current study builds on previous work...

Brains response to visual stimuli helps us to focus on what we should see, rather than all there is to see

Delving ever deeper into the intricate architecture of the brain, researchers at The Salk Institute have now described how two different types of nerve cells, called neurons, work together in tiny sub-networks to pass on just the right amount and the right kind of senso...

Computer models aid understanding of antibody-dependent enhancement in spread of dengue fever

...ons. Enhancement results in larger booms, but also deeper troughs in incidence, which lead to extinction. Although the computer models were specifically developed for dengue, the researchers believe the results could apply to any disease in which partial immunity increases pathogen replication rates. "Exp...
