Philandering female felines forgo fidelity

...tributing to the next generation than we thought,” added Durant. “This is good news for cheetahs, and a reminder that future conservation strategies need to encompass large landscapes if females are to continue to have access to many males.” In addition to helping save cheetahs in Africa, WCS is also st...

Pistachios lower cholesterol, provide antioxidants

...eding experiment to test the effects of pistachios added to a heart healthy moderate-fat diet on cardiovasc... fat and 8 percent saturated fat. The researchers added pistachios into the diets by including about half the amount of pistachios as a snack and by incorpo...

Technique monitors thousands of molecules simultaneously

...ng to a neighboring electrode a second reagent was added to the solution above the chip that destroyed the palladium(II) reagent. In this way, nothing happened at electrodes that were not being used. Reversing the polarity of things "The chip is an ongoing battle between active reagent and inactive r...

Climate change impacts stream life

...degree Celsius rise in temperature. Dr Durance added "The numbers of species in the streams we examined might also fall by 12-25 per cent if trends continue as expected over the next 50 years". ...

Scientists identify prion's infectious secret

...he array with peptides from baker’s yeast and then added prion protein to the array, also from the same yeast species. He found that a small cluster of peptides recruited the prion proteins to misfold into an amyloid structure. This region of the protein, which Tessier called a "recognition element," const...

Palau's coral reefs show differential habitat recovery following the 1998 bleaching event

...l controllable factors," says van Woesik. "They’re added to global effects of greenhouse gas emissions that affect climate change. The take-home message is that we can accelerate the recovery rate of coral reefs by adapting human behavior and reducing local pressure on reefs; this research provides encoura...

Chemical maps hint at drug's effects on schizophrenia

...g us more information about how these drugs work," added Ranga Krishnan, M.D., chairman of psychiatry and senior study investigator. "Now we can begin to develop better medicines that target the specific metabolites important for the disease but not those that could lead to detrimental side effects." Al...

Iowa State scientists demonstrate first use of nanotechnology to enter plant cells

...tes" not only prevented chemical leakage, but also added weight to the nanoparticles, enabling their delivery into the plant cell with the standard gene gun. The biologists successfully used the technology to introduce DNA and chemicals to Arabidopsis, tobacco and corn plants. "The most tremendous ...

Study of protein folds offers insight into metabolic evolution

... 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 mosaic of protein fold evolution. The mosaic shows that modern metabolic networks...

Uniform language for describing genes of pathogenic and beneficial microbes

...t is called The Gene Ontology (GO). The new terms added to the GO will significantly bolster what is already a powerful tool for scientists to compare the functions of genes and proteins in a wide range of disease-related organisms. The ongoing initiative is part of the Plant-Associated Microbe Gene Ontol...

Discovery of new cave millipedes casts light on Arizona cave ecology

...the tip of the proverbial iceberg," he said. He added that this also means more work for resource managers, who will now have to pay much closer attention to the use and conservation of these caves and their biological attributes. Neil Cobb, curator of the Colorado Plateau Museum of Arthropod Biodiv...

Blood sugar's manufacture limited by building blocks' supply

...n glucose production] due to a loss of substrate," added Susan Gray of Brigham and Women's Hospital. During fasting, the supply of glucose derived from food dries up, Gray explained. In response, the body first breaks down liver glycogen, the principal storage form of glucose. However, the body "goes th...

Despite their heft, many dinosaurs had surprisingly tiny genomes

...long before the first birds and flight, and can be added to the list of dinosaur traits previously thought to be found only in modern birds, including feathers, pulmonary innovations, and parental care and nesting." Other researchers had previously determined that the sizes of various cell types, across...

Gene found for rare disorder may reveal new pathway in mental retardation

Researchers learn what sparks plant growth

...l environment. Thus, it’s a question of survival," added Chory. "It took us 10 years to develop the tools to ask the question. It is very satisfying for me to see the results." Roots and shoots are a plant’s two major organ systems. For this study, published in the March 8, 2007, issue of the journal Na...

Tracking sperm whales and jumbo squid

Despite the vital role that jumbo squid and sperm whales play in oceanic ecosystems and fisheries, many aspects of their lifest...

Discovery could lead to better control of hemorrhagic fever viruses

...n, used by the virus to gain entry into cells, and added it to cells from African green monkeys, known to be highly susceptible to Machupo virus infection. Later, they broke the cells open and isolated the spike protein and the cellular protein to which it had attached itself. Then, using a technique call...
