Canola study solves seed oil mystery

... When it came to canola, the biochemical balance sheet just didn't add up. As far as researchers could tell, the seeds were relying on a creaky and inefficient pathway to produce their sought-after oil. All plants employ carbon from carbon dioxide to make organic biomass compounds such as sugars, ...

Falling ants glide back to trunk to avoid dangers of forest floor

... the same species of ant in freefall, with a white sheet standing in for the tree trunk. Yanoviak's earlier observations combined with the videotaped tests in Panama established that the ants basically reorient their bodies so their hind legs and abdomen point toward the tree, and use their head-up fall th...

The transparent organism: EMBLEM and Carl Zeiss give labs a unique look at life

... fuzzy. In SPIM, a sample is passed through a thin sheet of light, capturing high-quality images layer-by-layer. The sample can be rotated and viewed along different directions, further eliminating the blurry and unwanted light which prevented scientists from looking deep into tissues in the past. The enti...

JBC study shows that bigger isn't necessarily better for amyloid proteins

...folded monomers are not toxic because there are no sheet edges. Fibrils are much less toxic because the sheet edges are only exposed at the two ends of a very long fibril." Based on the above findings, Dr. Glab...

DOE JGI announces 2006 Community Sequencing Program portfolio

DOE JGI will be sequencing this community of microbes to provide a better understanding of the biochemical pathwa...

New collision looks imminent for B-15A iceberg

... B-15 and its descendants are a consequence of ice sheet dynamics or other factors. Together they will provide insight into whether such iceberg calving occurrences are becoming more common, as well as improving our understanding of the relationship between the Earth's ice cover and the global climate....

Unrestrained retina too much of a good thing

...ch point they started to develop one large, folded sheet of retina, instead of a retina and an optic nerve. "We were fascinated by our results because they were so dramatic," said Lemke. "The layers of the retina were perfectly formed but the retina reached all the way to the brain and there was no optic n...

The lopsided brain: Attention bias is shared by humans and birds

...cancel-out" evenly distributed visual targets on a sheet of paper placed before them. The finding that birds also exhibit spatial pseudoneglect is somewhat surprising, given that birds lack a corpus collosum, the structure in human brains that is thought to facilitate rapid communication between the two he...

Researchers get first peek at amyloid's spine

...ious ability of a fungal prion depends on its beta sheet structure, which he proposed would look similar to the detailed structure from Eisenberg's lab. In another interesting finding, the zipped up fibril core is dry. "Proteins love water," said Eisenberg. "When they are soluble, there is water all aroun...

Tagging pathogens with synthetic DNA 'barcodes'

Or the color can be observed directly through a fluorescent light microscope, which is useful in situations where the geographic distribution of the target molecules is important, Luo said. For co...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

...d in early 2002. Roughly 500 billion tonnes of ice sheet (3,250 square kilometers, about the size of Rhode Island) disintegrated in less than a month, what scientists have called "staggering" speed. The work builds on that of marine scientists who have plumbed the depths of the Weddell Sea, off the ...

Acupuncture versus acid reflux: 40% cut in sphincter relaxations brings hope for relief

As for H. pylori, in a fact sheet on heartburn, HH and GERD, NIDDK includes these poignant observations: "Much research is needed into the role of the bacterium Helicobacter pylori. Our ability to eliminate H. pylori has been responsible for reduced rates of peptic ulcer disease and ...

Study casts doubt on 'Snowball Earth' theory

...ove that large parts of the ocean remained free of sheet ice during the pre-Cambrian glaciation. It is statistically unlikely but possible, Olcott said, that the drill core found one of the tiny "refugia" for marine life whose existence is allowed under the "Snowball Earth" hypothesis. But, she said, "find...

Abalones along Pacific coast may owe their huge, dinner-plate size to sea otters

...n oceans 42 million years ago as the Antarctic ice sheet developed, followed much later, perhaps 10 million years ago, by radiation into the northern oceans as the Artic froze over. The current study, in which Wray used DNA comparisons to determine the family tree of the abalones, supports these dates. The...

Breakdown of myelin insulation in brain's wiring implicated in childhood developmental disorders

...ease rather than simply the symptoms." Myelin is a sheet of lipid, or fat, with very high cholesterol content -- the highest of any brain tissue. The high cholesterol content allows myelin to wrap tightly around axons, speeding messages through the brain by insulating these neural "wire" connections. Bart...

The unfolding of amyloid's true colors

Finally, Fowler et al. satisfy a burning question: are M{alpha} amyloid fibers serving a function in melanin synthesis? After reconst...
