The critical importance of mangroves to ocean life

...s are one of the main sources of dissolved organic matter in the ocean. The researchers note that the organic matter that is dissolved in the world oceans contains a similar amount of carbon as is stored in the skies ...

Alaska seal pup diet may hold key to decline of population

...n addition, the researchers are: Examining fecal matter to see how efficiently the animals in the two groups digest their food. Animals on the low fat diet may be processing their food less efficiently and eliminating needed nutrients. Measuring bone growth to see if one group grows more quickly. Monit...

Computer scientist sorts out confusable drug names

...and look-alike drug names with great accuracy in a matter of seconds," he added. Drug companies covet finding good, short drug names that are easy to remember, Kondrak noted, adding, "the FDA and other drug agencies need to balance this against confusing the names with existing ones--it's a serious problem....

Nanopore method could revolutionize genome sequencing

...describes a method to sequence a human genome in a matter of hours at a potentially low cost, by measuring t...uration of electrodes, but they think it is only a matter of time before someone successfully assembles the device. The nanopore and the electrodes have been...

Taipan venom no snake oil

...t called Factor X which could stem blood flow in a matter of seconds. A drug lead based on Factor X is being evaluated for clinical trials by bio pharmaceutical development company QRxPharma. "Australian snakes literally have a two-pronged attack when they bite their prey," Dr St Pierre said. "Firstly, v...

Brittlestar provides new model for stem cell research

... of the starfish and can regenerate lost arms in a matter of weeks. Sam Dupont and Mike Thorndyke are presenting their latest work on Friday 7th April at the Annual Meeting for the Society for Experimental Biology [session A8]. "What is really amazing is that the nervous system starts to be functional only...

Ancient fossil DNA found preserved in crystal

...te ?a substance that removes all traces of organic matter ?the clusters of crystals remain intact and the organic material embedded in them is unaffected. Now, almost 20 years later, Weiner and Salamon have returned to these findings, reasoning that fossil bones might possess such crystal structures contain...

New vaccine for condition that kills 500,000 children a year

...ases at EVMS' Center for Pediatric Research. "In a matter of hours, vomiting and diarrhea from rotavirus can lead to dehydration, which can result in hospitalization and even be life-threatening." Rotavirus causes about 70,000 hospital admissions in the United States annually, or about five percent of all ...

U-M researchers take new approach to defeating Gram-negative bugs

... "Bugs are very smart," Woodard said. "It's not a matter of if a bug will become antibiotic resistant, but when. We have to work hard to get ahead of them." ...

Plant-derived vaccines safeguard against deadly plague

...is the rapidity of the system," said Santi. "In a matter of 10 days, we can go from infecting the plants to harvesting the plants. From there, we purify the antigens in an additional one to two weeks to create the vaccine." The approach also eliminates the typical year-long lag time necessary to establish...

Oops! Researchers publish new findings on the brain's response to costly mistakes

It happens to all of us, no matter how hard we try. Whether it's deleting a computer file and realizing a split-second later that we can't get it back, or dropping a bag of groceries, or realizing that our gas tank is nearly empty on a lonely stretch of highway, we all make mistakes t...

Research could lead to better drugs and whiter whites

...caused by the resistance to a reaction by allowing matter to 'flow through' the barrier ?a process known as quantum mechanical tunnelling. "We have provided new insight into how enzymes work from painstaking efforts of a large interdisciplinary group based on detailed experimental observations and theoreti...

Scientists re-engineer a well-known antibiotic to counter drug resistance

...tance. The results, Boger added, suggest that no matter how the VRE altered the cell wall component, it was still sensitive to treatment by the re-engineered vancomycin analogues. "The complex chemical synthesis of the glycopeptide antibiotics was developed with the specific idea that this breakthrough ...

Neuroscientists discover new cell type that may help brain maintain memories of smells

...ect was shortened from potentially years to just a matter of weeks", said Pressler. The multiphoton microscope used in this study was built by Strowbridge specifically for these types of experiments and was funded by grants from the Mt. Sinai Health Care Foundation and the National Institutes of Health. ...

Cloned stem cells prove identical to fertilized stem cells

... "This paper demonstrates clearly that it doesn't matter if a stem cell has been derived from a cloned embryo or from a fertilized embryo," says Whitehead Member Rudolf Jaenisch, senior author on the paper that will appear in the online the week of January 16 in the Proceedings of the National Academy of S...

Front-line immune cells mature in four stages, study shows

...red where to look (in lymph tissue), it was just a matter of careful, diligent work." The researchers also isolated cells of each stage and showed that under the proper conditions, stage-1 progenitor cells matured into stage-2 NK cells, and that these cells matured into stage-3 cells and stage-4 cells, wi...

Aggression-related gene weakens brain's impulse control circuits

... found that those with L showed reductions in gray matter (neurons and their connections) of about 8 percent in brain structures of a mood-regulating circuit (cingulate cortex, amygdala) among other areas. Volume of an area important for motivation and impulse regulation (orbital frontal cortex) was increas...

Newly discovered protein kills anthrax bacteria by exploding their cell walls

...te, the PlyPH protein will kill them, usually in a matter of minutes. The combined solution could be used in buildings, on transportation equipment, on clothing, even on skin, providing a safe, easy way to fight the spread of anthrax in the event of a mass release. ...
