The paper, published Nov. 20 in the peer-reviewed US journal Proceedings of the National Academy of Sciences was created by six experts from diverse academic disciplines (forestry, environmental technology, ec...

Developing uses for sugar-cane bagasse: Biotechnology applied to the paper industry

...onal treatment using hydrogen peroxide in order to yield paper for printed and writing. P. cinnabarinus ...dry bagasse support). This amounts to 45 times the yield obtained without ethanol. Moreover, it appeared that little or no ethanol introduced was consumed by...

New engineered drug may offer prolonged arthritis relief

...g "fusion proteins." As the proteins degrade, they yield simple amino acids, which are the building blocks of all proteins. By experimenting with composition, molecular weight and concentration of various ELPs, Betre developed a protein for use in joints that would precipitate out of solution and clump a...

The first tree genome is published: Poplar holds promise as renewable bioenergy resource

...urn can be fermented into alcohol and distilled to yield fuel-quality ethanol and other liquid fuels. Poplar is the most complex genome to be sequenced and assembled by a single public sequencing facility and only the third plant to date to have its genome completely sequenced and published. The first, ...

Pleasure and pain: Study shows brain's 'pleasure chemical' is involved in response to pain too

...imes of intense stress in their lives. It may also yield clues to why some, but not other chronic pain patients may be prone to developing addictions to certain pain medications. And, it gives further evidence that vulnerability to drug addiction is a very individual phenomenon ?and one that can't be predi...

Wheat gene may boost foods' nutrient content

New biologic treatment for tennis elbow may replace surgery for chronic sufferers

... more commonly-used therapies which have failed to yield results, often resulting in surgery, concludes study authors Allan Mishra MD and Terri Pavelko, PAC, PT, of the Menlo Medical Clinic, Stanford University Medical Center, Menlo Park, Calif. "Ours is the first in vivo human investigation of this nove...

Fat stem cells being studied as option for breast reconstruction

...hole fat removed in a tummy tuck, for example, can yield up to 200 million stem cells, which in culture can be expanded by 10 times over the course of two weeks. If and when fat-derived stem cells are tried in patients for breast reconstruction, Dr. Rubin predicts surgeons will obtain the cells from the pa...

Biotech cotton provides same yield with fewer pesticides

...applied pesticides. The researchers compared the yield and pesticide use for 40 fields of non-Bt cotton, 21 fields of Bt cotton and 20 fields of Bt cotton that was also herbicide-resistant. In addition, each cotton field selected for the study was next to an uncultivated area. That allowed the research...

Parasitic plants sniff out hosts

... 20 percent infestation of the tomato crop reduces yield by 25 percent and causes a loss of 4 million dollars." The researchers used a variety of experiments to determine how newly emerging dodder shoots find a host. The length of time these parasites can live without a host is determined by the amount...

MRSA vaccine shows promise in mouse study

...es, a graduate student in the Schneewind Lab, "may yield a molecular appreciation of immunity against S. aureus and permit rational development of a vaccine." Schneewind and colleagues are now exploring the relationship between antibodies that fight S. aureus infection and surface proteins of the bacteriu...

The brain's motivation station

...d whether the image of a scene that followed would yield $5 or ten cents if they remembered it the next day. Then they showed the subjects the scene, and the next day tested their ability to pick the scene out of a group. The researchers found that the subjects were far more likely to remember high-value ...

Embryos exposed in 3-D

.... The Filter Harvest System also exhibited higher yield of MNCs for significantly better recovery (60 to 95 percent) than the Ficoll method. The Pall Filter Harvest system can be used as a closed system that adheres to Good Manufacturing Practice (cGMP), furthering the ability to comply with increasing...

Bacteria have their own immune system protecting against outside DNA

... the useful protein. However, in that process, the yield of some human proteins produced in bacteria can be low. The new research indicates that the H-NS "immune system" may be responsible for interfering with the expression of human genes in bacteria. "Having a better understanding of this system could ...
