Magnetism and mimicry of nature hold hope for better medicine, environmental safety

...s," it promises more rapid, more accurate and less costly analyses of water and biological fluids ?blood, urine, saliva ?that require only miniscule amounts of fluids. A detailed explanation of the process is presented in an article published in the July 17 edition of Applied Physics Letters, a leading in...

Pollution threatens coral health by preventing lesions from healing, UCF study shows

...self against contaminants, but it is metabolically costly for coral to produce, leaving less energy available to repair damaged tissue. Fauth's team is sharing data with Professor Michael Risk of McMaster University in Ontario, Canada, and marine ecologist Brian LaPointe of the Harbor Branch Oceanographic...

Better sludge through metagenomics

...n--the detritus of human activities--necessitating costly and environmentally taxing remedies and exposing the public to potential disease hazards. The scale is daunting--more than 31 billion gallons of wastewater are treated daily in the U.S. alone. Even a marginal improvement in the process would transla...

Too mellow for our predatory world

...pecially those animals that did not engage in such costly behaviour, providing them with an advantage in terms of fitness", speculates Roedl. The scientists’ findings are a first indication why tame animals have become extinct in many continents but also provide fresh arguments for conservation biologists...

Replacing insulin is top-ranked breakthrough foreseen for health in developing world

Eliminating the need for costly insulin injections for diabetics, regenerating hea...noted, adding that repeated insulin treatments are costly and therefore inaccessible to many developing country patients. The 2nd-ranked application, regen...

Why do insects like to eat some plants more than others?

...an attract enemies means that sex may be even more costly than previously though. This research also has implications for weed control and protection of rare plant species. ...

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

...gh overall levels of copper -- levels that are too costly to remove efficiently on a large-scale industrial basis. The PNAS report highlights the team's novel use of "excess reducing agents" to lower the amount of copper catalyst from 5,000 parts per million (ppm) to 10 ppm. The team showed that you can ...

Archerfish tune their shots to universal properties of prey adhesion

...he archerfish's hunting technique is metabolically costly and that the fish tune the force of their water shots by adjusting the mass of water in a shot, rather than altering the initial release pressure and speed of the shot. This turns out to be the most efficient way of adjusting force--by doubling the m...

BC catalyst discovery promises faster, cheaper drug production

...t-of-its-kind catalyst that will eliminate several costly and wasteful steps from the process of synthesizing certain molecules. "Our new catalyst will significantly improve the efficiency with which biologically and medicinally active molecules can be prepared," said Prof. Hoveyda, who is also chair of th...

A silent pandemic: Industrial chemicals are impairing the brain development of children worldwide

...the nervous system. Treating NDDs is difficult and costly to both families and society. In recent decades, a gathering amount of evidence has linked industrial chemicals to NDDs. Lead, for example, was the first chemical identified as having toxic effects to early brain development, though its neurotoxicity...

Fungal factories may save hemlock forests

...factory and then transporting it out to a forest—a costly proposition—their factory will be the forest. Or, more accurately, tiny droplets of sweet whey—a cheap waste product of cheese production, inoculated with the right concentrations of the target fungus—will be their factory. By spraying the whey solut...

Fish can determine their social rank by observation alone, study finds

...ngth of rivals before engaging them in potentially costly fights should be highly adaptive." When A. burtoni males fight, it's easy to spot the winner. Mature males have a menacing black stripe, or eyebar, on their face. After a fight, the winner retains his showy appearance, but the loser's eyebar tempo...

Bacteria research offers hope for new vaccine against meningococci

...e candidates and new drugs, obviating the numerous costly and time-consuming tests that have been necessary until now. At the same time, the system provides a clear picture of the process of infection. “With these findings as tools, we can continue to study the course of the disease and test vaccines on...

How to manage forests in hurricane impact zones

...canes Katrina and Rita caused what may be the most costly natural disaster in U.S. history, with over 5.5 million acres of timberland in the coastal states of Texas, Louisiana, Mississippi, and Alabama affected. Using available data on the damage from these storms, the researchers constructed an adaptive st...

Researchers hot on the trail of brain cell degeneration

Cooperation between biocentres gets research going The teams' study is a perfect example of the cooperation between biocentres in Finland (Biocenter Finland) and international networ...

Machine preservation may promote more organ sharing

... not new, it is not widely used because it is more costly and labor-intensive. According to the United Network for Organ Sharing, only 21 percent of kidneys from deceased donors are preserved on a pump. The purpose of this study was to compare outcomes in kidney transplant patients receiving kidneys from...

ASU research shows connection between testosterone, dietary antioxidants and bird coloration

... “This study shows that testosterone may not be as costly as previously thought, so long as animals can nutritionally offset the immune detriments of testosterone. They may even experience a net health benefit as a result,” explained McGraw, who studies the functions of naturally occurring chemicals in bird...

Researchers examine carbon capture and storage to combat global warming
