Study calculates patient time costs associated with cancer care

...United States and that this cost derives from many sources ?." The editorial writers also note that these calculations do not address the emotional cost cancer patients and their families endure. Even accounting for patient time costs, "we know we have greatly underestimated the true cost of the disease,"...

Genome sequencing reveals key to viable ethanol production

As the national push for alternative energy sources heats up, researchers at the University of Rochester have for the first time identified how genes responsible for biomass breakdown are turned on in a microorganism that produces valuable ethanol from materials like grass and cornstalks. Waste produ...

Leeches ferry infection among newts

...y fertilizer-laden wastewater from farms and other sources often causes increased growth of aquatic vegetation in ponds, providing leeches with a firmer footing. "It could lead to more leeches and create potential hotspots of disease," Raffel noted....

Cornell lab confirms deadly fish virus spreading to new species

...still relatively new to the region. Other possible sources of the virus include the movement of infected fish by airborne or terrestrial predators, anglers using infected bait minnows, contaminated fishing equipment or live water wells in boats, boating activities and ballast water. "Basically, we don’t kn...

Study of protein folds offers insight into metabolic evolution

....manet.uiuc.edu/index.php ) which links these data sources into a new global network diagram of metabolic pathways. The researchers added color, representing evolutionary age, to their diagrams of metabolic networks (for an example, see the purine metabolism network in MANET). The result is a multicolored...

Hexavalent chromium in drinking water causes cancer in lab animals

...ld consume from the most highly contaminated water sources identified in California. The researchers report finding significant increases in tumors at sites where tumors are rarely seen in laboratory animals. Male and female rats had malignant tumors in the oral cavity. The studies conducted in mice fo...

Invasion of the island bats

..., it seemed only logical that continents were rich sources from which islands drew only a small sample. Once isolated and with fewer species around, island organisms were thought to lose their competitive edge and so they hardly ever re-colonized the continent from which they originated. These views suff...

Hawaiian treasure, macadamia nuts good for the heart

...riel. "We substituted the macadamia nuts for other sources of fat and protein in the diet. For example, we could switch skim milk for 2 percent milk and add some macadamia nuts." Macadamia nuts are native to Australia, but were imported to Hawaii and thrived. The first commercials crop of Hawaiian macadam...

New research shows sharks use their noses and bodies to locate smells

Scientists close in on missing carbon sink

...of scientists analyzed them to obtain a picture of sources and sinks of carbon on a global level. The research team compared the air samples to estimates of airborne carbon dioxide concentrations generated by the computer models. The scientists found that most of the models significantly underestimated th...

University of Pittsburgh School of Medicine researchers develop 'off-the-shelf' vascular grafts

...y diseases, where there is a critical need for new sources of blood vessels for vascular grafts. The saphenous vein taken from a patient’s leg continues to be the most commonly used graft for coronary artery bypass grafting even though a significant percentage of vein grafts eventually fail. Arterial grafts...

Researchers examine carbon capture and storage to combat global warming

...sil fuel use, if fossil fuels from some stationary sources can be used more cleanly. But the researchers continually emphasize the need to adopt other technologies in addition to carbon sequestration. ''Geological sequestration is going to be one of a family of solutions for addressing the greenhouse g...

Researchers find 24 species believed new to science in Suriname rainforest
