A team of Whitehead Institute scientists has discovered the surprising manner in which an enigmatic protein known as SUUR acts to control gene copy number during DNA replication. It's a finding that could shed new light on the formation of fragile genomic regions associated with chromosomal abnormalities.

A population of endangered giant tortoises, which once dwindled to just over a dozen, has recovered on the Galapagos island of EspaƱola, a finding described as "a true story of success and hope in conservation" by the lead author of a study published today (Oct. 28).

Glioma is a common name for serious brain tumours. Different types of glioma are usually diagnosed as separate diseases and have been considered to arise from different cell types in the brain. Now researchers at Uppsala University, together with American colleagues, have shown that one and the same cell of origin can give rise to different types of glioma. This is important for the basic understanding of how these tumours are formed and can contribute to the development of more efficient and specific glioma therapies. The results have been published in Journal of Neuroscience.

In the on-going effort to develop advanced biofuels as a clean, green and sustainable source of liquid transportation fuels, researchers at the U.S. Department of Energy (DOE)'s Joint BioEnergy Institute (JBEI) have identified microbial genes that can improve both the tolerance and the production of biogasoline in engineered strains of Escherichia coli.

'Our premise is that mechanics play a role in almost all biological processes, and with these DNA-based tension probes we're going to uncover, measure and map those forces,' says biomolecular...
Adherent cells, the kind that form the architecture of all multi-cellular organisms, are mechanically engineered with precise forces that allow them to move around and stick to things. Proteins called integrin receptors act like little hands and feet to pull these cells across a surface or to anchor them in place. When groups of these cells are put into a petri dish with a variety of substrates they can sense the differences in the surfaces and they will "crawl" toward the stiffest one they can find.

Encapsulated toxin-producing stem cells (in blue) help kill brain tumor cells in the tumor resection cavity (in green).
Harvard Stem Cell Institute scientists at Massachusetts General Hospital have devised a new way to use stem cells in the fight against brain cancer. A team led by neuroscientist Khalid Shah, MS, PhD, who recently demonstrated the value of stem cells loaded with cancer-killing herpes viruses, now has a way to genetically engineer stem cells so that they can produce and secrete tumor-killing toxins.

Like a slumbering dragon, HIV can lay dormant in a person's cells for years, evading medical treatments only to wake up and strike at a later time, quickly replicating itself and destroying the immune system.

Researchers have created a cellular probe that combines a tarantula toxin with a fluorescent compound to help scientists observe electrical activity in neurons and other cells. The probe binds to a voltage-activated potassium ion channel subtype, lighting up when the channel is turned off and dimming when it is activated.

Scientists in Cambridge have found hidden signatures in the brains of people in a vegetative state, which point to networks that could support consciousness even when a patient appears to be unconscious and unresponsive. The study could help doctors identify patients who are aware despite being unable to communicate.
