Israel's kibbutz movement continues to shift from the

SwRI researchers offer explanation for the differences between Ganymede and Callisto
Differences in the number and speed of cometary impacts onto Jupiter's large moons Ganymede and Callisto some 3.8 billion years ago can explain their vastly different surfaces and interior states, according to research by scientists at the Southwest Research Institute appearing online in Nature Geoscience Jan.

Bat researchers no longer flying blind on echolocation
Researchers at the University of Western Ontario (Western) led an international and multidisciplinary study using micro-computed tomography systems to shed new light on the way bats echolocate.

Genes found linked to breast cancer drug resistance could guide future treatment choices
Researchers at Dana-Farber Cancer Institute have discovered a gene activity signature that predicts a high risk of cancer recurrence in certain breast tumors that have been treated with commonly used chemotherapy drugs.

Monarch butterflies reveal a novel way in which animals sense the Earth's magnetic field
Building on prior investigation into the biological mechanisms through which monarch butterflies are able to migrate up to 2,000 miles from eastern North America to a particular forest in Mexico each year, neurobiologists at the University of Massachusetts Medical School have linked two related photoreceptor proteins found in butterflies to animal navigation using the Earth's magnetic field.

Levitating magnet may yield new approach to clean energy
A new experiment that reproduces the magnetic fields of the Earth and other planets has yielded its first significant results.

Illuminating protein networks in 1 step
A new assay capable of examining hundreds of proteins at once and enabling new experiments that could dramatically change our understanding of cancer and other diseases has been invented by a team of University of Chicago scientists.

Living the high life is risky business for toads under threat from fungus
Midwife toads that live in the mountains are highly likely to die from a serious fungal infection, called chytridiomycosis, whereas their infected relatives in the lowlands are not, according to new research published today in Ecology Letters.

How 'random' lasers work
When University of Utah scientists discovered a new kind of laser that was generated by an electrically conducting plastic or polymer, no one could explain how it worked and some doubted it was real.

Researchers trace effects of genetic defect in myotonic muscular dystrophy
Research on the genetic defect that causes myotonic muscular dystrophy has revealed that the mutation disrupts an array of metabolic pathways in muscle cells through its effects on two key proteins.
