Which came first, the moth or the cactus?

...n the community ecology of mutualism -- the larger puzzle -- and this moth-cactus relationship is just one piece of that," Holland said. "When we discovered the relationship in 1995, I immediately thought of using it to look at the bigger picture. But in aiming to do that, I wound up spending a decade worki...

Abnormal fat metabolism underlies heart problems in diabetic patients

"By exploiting the novel technology of shotgun lipidomics, we have identified the increased activation of certain lipid-digesting enzymes and the decrease of cardiolipin as ce...

Study sheds light on why humans walk on two legs

Piecing together the cyanobacteria puzzle

...The new method should help to clear up the age-old puzzle of how different species of blue green algae can fix or take up atmospheric nitrogen and carbon in a single cell organism. Carbon fixation during photosynthesis produces oxygen, which inhibits nitrogen fixation. Different species of blue green alg...

Maynard Olson receives $500,000 Gruber Genetics Prize

... human genome would have been an impossible jigsaw puzzle without the work of Maynard Olson. He created a way of breaking genomes into manageable pieces, applied it to the yeast genome, and made the human genome project a possibility. Now he is working to apply genome science to real biological problemssta...

St. Jude study shows genes play an unexpected role in their own activation

... gene. This finding adds an important piece to the puzzle of how cells use CREB to activate specific genes in response to cAMP signals. It also suggests that the current model scientists use to explain how CREB works is too simple, said Paul Brindle, Ph.D., associate member of the Department of Biochemis...

Northern forests less effective than tropical forests in reducing global warming

...his research fills in another piece of the complex puzzle on how the Earth system functions," said Cliff Jacobs of NSF's Division of Atmospheric Sciences. "These findings will be viewed as a milestone in discoveries about our planet's 'metabolism.'" Stephens and his colleagues analyzed air samples that ha...

Researchers isolate new risk marker for overweight children

...hylomicron levels may be an important piece to the puzzle in understanding just who is and who isn't at risk of CVD." Proctor believes testing for apoB48 may become more common and less expensive as people realize how important it is in determining CVD risk. And while Proctor and his colleagues believe ...

New tumor markers -- 'Spot the differences'

...t have easy drawings with just a few lines as in a puzzle (Figure A). Instead, we compare complex images with hundreds of thousands of different intensity points. In our study we identified a total of 116 messages that were over-expressed in cancerous cells. These findings reveal some of the orders that a...

...e air. "This work finds the missing piece of the puzzle that has fascinated many generations of solar astronomers," said Alexei Pevtsov, program scientist at NASA. "If you fit this piece into place, the whole picture of chromosphere heating becomes more clear." Over the past twenty years, scientists hav...

Alarming acceleration in CO2 emissions worldwide

... According to Field, solving the first part of the puzzle requires shifting more of the economy toward activities like service industries and information technology, where emissions can be lower, and emphasizing energy efficiency. Solving the second requires deploying new sources of non-emitting energy like...

Left-right wiring determined by neural communication in the embryonic worm

...rcent of the time. "What makes this an interesting puzzle to solve is understanding how the left and the right side become different from each other, and how they coordinate their activity so that every worm still has exactly one of each type of cell," says the paper's senior author Cori Bargmann, Torsten N...
