More recycling on the farm could reduce environmental problems

...use lower inputs of pesticides and energy and more recycling of energy and materials, according to an article published in the May 2007 issue of BioScience. The author, Craig J. Pearson of the University of Guelph, documents how semiclosed agricultural systems -- which he terms "regenerative" -- could enhance ...

Fish extinctions alter critical nutrients in water, study shows

...ts important fish species that play major roles in recycling nutrients. In fact, 20 percent of fish species acc...ecies successfully picked up the slack in nutrient recycling left by an extinct species, nitrogen and phosphorus were maintained at 80 percent of their starting ...

Nonvenomous Asian snakes 'borrow' defensive poison from toxic toads

...orrow a dose of poison by eating toxic toads, then recycling the toxins? That's exactly what happens in the relationship between an Asian snake and a species of toad, according to a team of researchers funded by the National Science Foundation (NSF) Division of Integrative Organismal Systems (IOS). Herpe...

Recycling technology

... competition to investigate ways of extracting and recycling liquid crystals from waste LCD devices. They are part of a consortium of nine partners and supported by the Resource Efficiency Knowledge Transfer Network (KTN) and the Displays and Lighting Knowledge Transfer Network. The DTI will fund 50% of a tot...

Carnegie Mellon scientists use 'green' approach to transform plastics manufacturing

...ew ATRP processes significantly reduce the cost of recycling the catalyst and also decrease the release of hazardous reaction byproducts found in industrial waste," Matyjaszewski added. During ATRP, scientists produce a complex polymer structure using a special catalyst to add one or a few monomer units at a...

End of deforestation in view? Experts advance new way to size up global forest resources

... the restoration of land to nature. Through paper recycling and a growing reliance on electronic communication, people help the transition by lessening demand for wood products." Anticipating impacts of expanding global trade The authors note that it's possible to sustain a large commercial harvest and...

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

...e inducer can, similarly, be envisaged as a way of recycling this compound, which constitutes one of the main pollutants emitted by the paper industry. ...

Soil nutrition affects carbon sequestration in forests

...ated CO2 by transferring carbon below ground, then recycling it back to the atmospheric through respiration. "With sufficient soil nutrition, forests increase their ability to tie up, or sequester carbon in woody biomass under increasing atmospheric CO2 concentrations," says Kurt Johnsen, SRS researcher i...

Recycled paper and compost could both be key tools to control plant disease

...s and homes. Professor Noble said: "During paper recycling production a large proportion of the fibres cannot be recycled. The useable fibres are taken out to make new newsprint, and the small fibres are no longer usable, they're a waste by-product. In Britain, about half a million tonnes of these small, un...

Federal testing for mad cow disease a failure, law review editor says

...ar, the slaughterhouse practice of "rendering," or recycling dead cows and sheep into protein for cattle feed, is believed to be widespread. Congress banned the practice in 1997 following evidence that feeding herbivorous cows the meat from dead animals can lead to the formation of abnormal proteins, or prio...

Odd energy mechanism in bacteria analyzed

...In the oceans, SAR11 is a partner in this process, recycling organic carbon and producing the nutrients needed for the algae that produce about half of the oxygen that enters Earth's atmosphere every day. The carbon cycle ultimately affects all plant and animal life on Earth. However, it's now clear that SAR...

GROWing the next generation of water recycling plants

A vegetated rooftop recycling system has been developed that allows water to be used twice before it is flushed into the communal waste water system. The Green Roof Water Recycling System (GROW) uses semi-aquatic plants to treat waste washing water, which can then be reused for ...

'Acid rain' and forest mass: Another perspective

...ing factor in productivity. In this research, the recycling of nutrients was studied in two, five-year period stages and in two young radiata pine forests (the first stage) and in two oak woods (the second). To this end, weekly samples of rain, transcolation (fraction of the precipitation that passes through ...

Mechanism for Epstein-Barr virus protein's role in blood cancers discovered

...egradation by the proteosome machinery, the cell's recycling plant. With Rb out of the way, the cell now reproduces uncontrollably. "It's as simple as that, but it's a major mystery solved that many researchers have been working on for at least 15 years," says Robertson. EBV, a member of the herpesvirus fam...

Newly Discovered Role for Heart Response Enzyme May Yield Better Heart Failure Therapy

...ergic receptors to be drawn back into the cell for recycling once they have been activated. Those studies showed that increases in PI(3)K underlie the loss of beta-adrenergic receptors in animals and patients with heart failure, Rockman said. The researchers' earlier experiments showed that disrupting the fun...

Gene discovery sheds light on causes of rare disease, cancer

...ng a chemical tag to Met that flags it for protein recycling or degradation. Since Met is on the outside surface of the cell and the recycling and degradation machineries are inside, the cell must bring Met inside through endocytosis in order ...

Bioinformatics reveals new gene regulation system

...t is synthesized, and enzymes that are involved in recycling nucleotide building blocks. Although the work does not have direct application to human medicine, Gelfand pointed out that many antibiotics work by attacking the process of bacterial DNA replication. So, he said, this work has identified potential t...

Amazon source of 5-year-old river breath

...said. "Previous studies failed to detect the rapid recycling of forest carbon because they never dated the invisible greenhouse gas as it is literally exhaled by the river organisms." "River breath is much deeper and faster than anyone realized," says Jeff Richey, UW oceanographer and another co-author. Carb...
