Novel label-free microscopy enables dynamic, high-resolution imaging of cell interactions
Researchers have invented a novel live-cell imaging method that could someday help biologists better understand how stem cells transform into specialized cells and how diseases like cancer spread. The Photonic Crystal Enhanced Microscope (PCEM) is capable of monitoring and quantitatively measuring cell adhesion, a critical process involved cell migration, cell differentiation, cell division, and cell death.

Cancer spread is increased by a high fat diet, ground-breaking evidence shows
New research shows that the metastatic process (cancer spread) is enhanced by fat intake. Mice given a high fat diet, including palmitic acid (a major component of palm oil which is found in lots of household products) developed the most aggressive cancer spread. The study identifies for the first time a protein called CD36 which has an essential role in cancer spreading.

Bacterial L-forms: An independent form of life that can multiply indefinitely
Bacteria able to shed their cell wall assume new, mostly spherical shapes. Researchers have shown that these cells, known as L-forms, are not only viable but that their reproductive mechanisms may even correspond to those of early life forms.

Plants modified to express fruit fly gene used to detoxify contaminated land
Scientists have discovered that a gene found in the common fruit fly can be successfully expressed in a plant and used to detoxify land contaminated with TNT.

Major Urinary Proteins do not allow kin recognition in male mice
The urine of house mice, unlike humans, contains large amounts of proteins, which are mainly major urinary proteins or MUPs. These proteins function to stabilize the release of volatile pheromones from urinary scent marks. MUP genes occur in a large cluster in mice, and there are 21 different MUP genes, whereas humans have only one MUP gene, which is no longer functional.

An amino acid controls plants' breath
Botanists demonstrate that the amino acid L-methionine activates a calcium-channel regulating the opening and closing of tiny plant pores.

Bacteria produce aphrodisiac that sets off protozoan mating swarm
Scientists have demonstrated that bacteria can drive mating in eukaryotes raises possibility that environmental bacteria or bacterial symbionts may influence mating in animals.

Experimental insecticide explodes mosquitoes, not honeybees
Entomologists report an experimental molecule that inhibits kidney function in mosquitoes and thus might provide a new way to control the deadliest animal on Earth.

New study of water-saving plants advances efforts to develop drought-resistant crops
As part of an effort to develop drought-resistant food and bioenergy crops, scientists have uncovered the genetic and metabolic mechanisms that allow certain plants to conserve water and thrive in semi-arid climates.

Small but mighty: Tiny proteins with big roles in biology
Scientists have discovered a small protein important for cellular housekeeping. The new molecule could provide a better understanding of how the levels of genes, including disease genes, are controlled in the cell.
