Magnetism's subatomic roots: Study of high-tech materials helps explain every...
Theoretical physicists have created a new model that helps define the subatomic origins of ferromagnetism -- the everyday "magnetism" of compass needles and refrigerator magnets. The model was created to explore the inner workings of ferromagnetic compounds that are related to high-temperature superconductors.

Hair provides proof of the link between chronic stress and heart attack
Researchers have provided the first direct evidence using a biological marker, to show chronic stress plays an important role in heart attacks. The scientists developed a method to measure cortisol levels in hair providing an accurate assessment of stress levels in the months prior to an acute event such as a heart attack.

Functional motor neuron subtypes generated from embryonic stem cells
Scientists have devised a method for coaxing mouse embryonic stem cells into forming a highly specific motor neuron subtype. The research provides new insight into motor neuron differentiation and may prove useful for devising and testing future therapies for motor neuron diseases.

Dutch biologist Gerard Jagers op Akkerhuis has developed the ?operator hierarchy? -- a system based on the complexity of particles and of organisms, which can predict the next step in evolution: a technical life form, that can pass on its knowledge and experience to the next generation.

Most new farmland in tropics comes from slashing forests, research shows
A new study shows that more than 80 percent of the new farmland created in the tropics between 1980 and 2000 came from felling forests, which sends carbon into the atmosphere and drives global warming. But the research team also noted that big agribusiness has largely replaced small farmers in doing most of the tree cutting in Brazil and Indonesia, which may make it easier to rein in the trend.

New animal model for hemophilia A developed
Researchers have developed a new animal model for studying hemophilia A, with the goal of eventually treating people with the disorder. Hemophilia A, a hereditary defect that prevents blood from clotting normally, is caused by a variety of mutations in the factor VIII gene.

Ants take on Goliath role in protecting trees in the savanna from elephants
Ants are not out of their weight class when defending trees from the appetite of nature's heavyweight, the African elephant, a new study finds. Columns of angered ants will crawl up into elephant trunks to repel the ravenous beasts from devouring tree cover throughout drought-plagued East African savannas, playing a potentially important role in regulating carbon sequestration in these ecosystems.

Mechanisms and function of a type of mysterious immune cell discovered
In two closely related studies, two teams of scientists have discovered the underlying mechanisms that activate a type of immune cell in the skin and other organs. The findings may lead to the development of new therapies to treat inflammation, wounds, asthma and malignant tumors.

The European Space Agency's Envisat satellite has been tracking the progression of the giant iceberg that calved from Greenland's Petermann glacier on 4 August 2010. A new animation shows that the iceberg, the largest in the northern hemisphere, is now entering Nares Strait -- a stretch of water that connects the Lincoln Sea and Arctic Ocean with Baffin Bay.
