Evolving designer ecosystem sheds light on unintended consequences

... is just one of a multitude of lakes, small ponds, canals and dams combining flood control, water delivery, ... fields and city taps," says Roach. "While these canals enabled farmers to grow crops in the desert, they ... of their historic supply of this material, canals accidentally alter the way nutrients are cycled ...

Dinosaur from Sahara ate like a 'mesozoic cow'

... Sereno and team to look inside the dinosaurs braincase. There, small canals of the brains balancing organ revealed the habitual pose of the head. Reconstructed from CT scans, these canals showed that the muzzle of Nigersaurus angled directly toward the ground, ...

Experimental treatment halts hypoxic-ischemic brain injury in newborns

... reduction and systemic hypoxia. The enzyme inhibitor was injected into the intracerebroventricular region of the brain, which includes a system of canals that distribute cerebrospinal fluid throughout the organ. The researchers found that injection of PAI-1 greatly reduced the activity of both tPA ...

More food at lower cost

... cells. What the model showed was very surprising: auxin is not delivered to root hair cells directly, but via the cells next door which act as canals through which the auxin is transported. During transport, some of the auxin leaks out, supplying hair cells with the auxin signal to grow. This new ...

NJIT professor's research suggests changes in underwater data communications

... existing systems because his uses acoustic particle velocity channels for data communication. These channels would be able to provide new and extra canals for data communication. There are obvious advantages to increasing the number of canals. Not only would they increase the speed and reliability ...

Experts to discuss global water crisis

... Need Water, Too! The Missing Piece in Water Policy," will focus on how current water infrastructure systems such as dams, reservoirs, pumps and canals have damaged the ecosystem and the natural ways that water is distributed to many areas of the world. She believes that a new system of strategies ...

Mussels to determine how much contamination is in the ports

... is to evaluate the methodology and tools of the sampling. The European Directive on water obliges government bodies to monitor contaminants in all canals and along all coasts. "We wish to know if our methodology and the sampling tools that we have developed are useful for this purpose", said Dr ...

'Nanoglassblowing' seen as boon to study of individual molecules

... wafer with the same lithographic procedures used to manufacture circuit patterns on semiconductor computer chips. The planar (flat-edged) rectangular canals are topped with a glass cover that is annealed (heated until it bonds permanently) into place. About a year ago, the authors of the Nanotechnology ...

Reconstructing the biology of extinct species: A new approach

... of its organ of balance, the three semicircular canals of the inner ear on each side of the skull. The ... of the dimensions of the semicircular canals to locomotion. These structures are filled with a fluid, which moves within the canals when the animal moves. The fluid's movement is ...

Stimulation of the semicircular canals can artificially control human walking and balance

... the key to human balance has come from a precise sense of--and ability to align the body to--the direction of gravity. However, the semicircular canals that the researchers stimulated to control walking and balance detect rotational movements of the head, not the direction of gravity. These findings ...

Medieval diaries aid scientists ascertain increase in hot spots due to global warming

... a record developed from diaries of people living in the Netherlands and Belgium over the past 750 years that revealed for example the years when the canals froze. ...

Gifts from the sea

... that must cram their nerves through relatively small openings in the skull. The human vestibular (balance) system relies on fluid-filled ear canals that tell us which end is up. The toadfish vestibular system is similar enough to the human version to make comparisons meaningful but with an easier ...

Solution to Pollution: New Bacteria Eats Toxic Waste
