Potential for enhanced sequestration of carbon in soils supports evaluations

...ers note that a variety of land-use practices have apparently favorable potential for increasing carbon dioxide uptake, including intensifying cropping, adding organic material to soil, conservation tillage, and afforestation and grassland establishment. Initial cost estimates of some of these practices appear ...

New research shows plants can shuffle and paste gene pieces to generate genetic diversity

...contained fragments of plant genes that the TE had apparently captured while it was copying itself. The fact that these instances were so rare suggested that this was not an important process." In analyzing the TE content of the entire rice genome, Ning Jiang and Xiaoyu Zhang, two postdoctoral fellows in the...

New fossil sheds light on old mystery

...orce that pushes the prey away. Dinocephalosaurus apparently took yet another approach. When it thrust its head forward to capture prey, the ribs along its neck would splay outward. This would increase the diameter of the esophagus, creating a suction force that would swallow the pressure wave created by the l...

European common frog found to use novel mating strategy

...erous clutches. What they uncovered was a strategy apparently linked to the unusually skewed operational sex ratio in the Pyrenean ponds, that is, the ratio of eager males to available females. For every female frog there were between four and 10 male frogs in a pond about half the size of an Olympic-size swimm...

Genetic analysis rewrites salamander's evolutionary history

...ethdontid salamanders, like all other salamanders, apparently went through a larval stage in fresh water, where the eggs are laid, before losing their gills and swimming tails and emerging onto land. Salamanders that evolved to live totally out of the water, however, lost the larval stage, emerging from the egg...

Can an old gene learn new tricks?

...agues show that the mouse Hmx2 and Hmx3 genes have apparently interchangeable functions in CNS development and have overlapping yet distinct functions in the development of the vestibular system of the inner ear, an organ that has no counterpart in Drosophila. The researchers found that when mice are genetical...

Missing genes may help explain why plague bacteria are so deadly

...y (LLNL) has found that several hundred genes that apparently were inactivated as the plague bacterium evolved may be largely responsible for its virulence. In a report published today (Sept. 9) in the online edition of the Proceedings of the National Academy of Sciences, the researchers said the "massive gene...

Bacteria use 'molecular lasso' to cop copper

... retrieved by bacterial cells, Kim said. The cells apparently latch onto copper-bearing methanobactin molecules, but what happens next isn't known. Also, unlike a cowboy's lasso, methanobactin has no tether to its mother cell. Therefore, when bacterial cells release their methanobactin molecules, they probably ...

Viral suspect for amphibian decline traced to human spread through bait

...rly in the project, the team began to focus on two apparently "emerging" pathogens in particular a chytrid fungus and an iridovirus both unfamiliar organisms, though geographically widespread. The chytrid fungus in particular appears to be responsible for major population declines and even waves of mass extin...

The insect police: Why social insects punish cheating comrades

...rent Keller explain how these policemen arise. The apparently altruistic behavior of workers in supporting their queen is generally explained by 'kin selection', whereby the worker obtains more 'reproductive payoffs' indirectly by producing the queen's offspring than by having their own. Kin selection revolves ...

The first engineering of cell surfaces in living animals

... just as many cell-surface azides, so esterase was apparently no hindrance to the uptake of the azide-containing precursor. The other half of the Staudinger ligation, the phosphine, may be attached to a great variety of markers. To confirm the success of the Staudinger ligation in mice, Bertozzi and her collab...

Marijuana ingredient inhibits VEGF pathway required for brain tumor blood vessels

... The researchers also discovered that cannabinoids apparently worked by increasing the activity of ceramide, a lipid mediator of apoptosis, resulting in the functional inhibition of cells needed for VEGF production. The ability of cannabinoids to alter VEGF production was significantly stifled following the int...

Despite darkness, nocturnal bees learn visual landmarks while foraging at night

...come nocturnal, and despite the darkness and their apparently insensitive compound eyes, they have retained remarkable visual abilities. In the new work, performed on Barro Colorado Island in Panama, the researchers used infrared night-imaging cameras to show that by performing special orientation flights, Mega...

U-M scientists find common virus in human prostate tissue

... in the cell's nucleus," explains Imperiale. "TAg apparently sequesters p53 protein in the cell's cytoplasm, preventing it from entering the nucleus and giving the signal for the cell to stop dividing and die." Imperiale's working hypothesis is that the BK virus infects epithelial cells in the pros...

Endangered turtles' trek along ocean currents revealed by satellite

...hey are working to uncover connections between the apparently meandering routes followed by turtles and the local ocean conditions, and so develop strategies to minimise the unintended but deadly threat posed to leatherbacks by deep-sea fishing. These giant reptiles - known to reach 2.1 metres in length and ...

In search of a lean gene

...nger than wild-type mice, but are markably leaner, apparently burning fat at a much higher rate than normal mice. Dr. Lee and colleagues observed that despite their svelte appearance, beta/beta mice actually eat more food and are no more active than their genetically normal littermates. In search of the cause ...

Hunt for a new plant hormone points to carotenoids

...late the degree of shoot branching. The hormone is apparently made throughout the plant, but hormone made in the roots is able to travel up the plant to influence branching in the shoot, suggesting that it may play a role in balancing root and shoot growth. In this issue of Current Biology, Ottoline Leyser and ...

NRH1 and Wnt signaling come together in convergent extension

... out, as do the specifics of the inter-related but apparently independent roles of NRH1 and PCP signaling in the control of cell movements within the developing embryo....

New discovery could provide tool to detect whether a cancer will develop and spread

... potential for metastasis can be detected early in apparently normal tissues. The study, which appears online this week, will be published in the August 3rd issue of the Proceedings of the National Academy of Sciences. This discovery challenges current thinking about how a cancer develops and spreads. Rare or...

JCI Table of Contents, 15 July 2004

... maturation could be completed in a test tube. The apparently reversible nature of the infertility block caused by innactivation of the Pde3a gene suggests that PDE3A may be a potential target for developing new contraceptives. The Pde3a knockout mouse will be an excellent model of female infertility for explor...
