Tiny Sacs Released By Brain Tumor Cells Carry Information That May Guide Treatment
Microvesicles - tiny membrane-covered sacs - released from glioblastoma cells contain molecules that may provide data that can guide treatment of the deadly brain tumor. Researchers have found tumor-associated RNA and proteins in membrane microvesicles called exosomes in blood samples from glioblast ... more »

The Bonsai Effect: Wounded Plants Make Jasmonates, Inhibiting Cell Division, Stunting Growth
Biologists found that when leaves of the model plant Arabidopsis are wounded, cell division in the apical meristem is reduced, growth of the plant is arrested within days, and the new leaves grow to only one-half of their normal size although the size of leaf cells is unaffected.

Chemical From Medicinal Plants May Be Used To Fight HIV
Immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division. As a result, its disease fighting ability is compromised. A new study finds that a chemical from the Astragalus root, frequently used used in ... more »

'Cascading Effect' Of Childhood Experiences May Explain Serious Teen Violence
Adverse experiences early in life can lead to minor childhood behavior problems, which can grow into serious acts of teen violence, according to new research. Children who had social and academic problems in elementary school often had parents who withdrew from supervision and monitoring during midd ... more »

Stem Cells With Potential To Regenerate Injured Liver Tissue Identified
A novel protein marker has been found that identifies rare adult liver stem cells, whose ability to regenerate injured liver tissue has the potential for cell-replacement therapy. For the first time, researchers have demonstrated that cells expressing the marker can differentiate into both liver cel ... more »

Nanotechnology: Quantum Computer May Be Closer With Extended Quantum Lifetime Of Electrons
Physicists have found a way to extend the quantum lifetime of electrons by more than 5,000 per cent. Electrons exhibit a property called 'spin' and work like tiny magnets which can point up, down or a quantum superposition of both. The state of the spin can be used to store information and ... more »
