EPFL scientists reveal that the brain is not as compact as we thought

Using an innovative method, EPFL scientists show that the brain is not as compact as we have thought all along. To study the fine structure of the brain, including its connections between neurons, the synapses, scientists must use electron microscopes. However, the tissue must first be fixed to prepare it for this high magnification imaging method.

USC researchers develop yeast model to study gene mutation that disrupts DNA duplication

Researchers at USC have developed a yeast model to study a gene mutation that disrupts the duplication of DNA, causing massive damage to a cell's chromosomes, while somehow allowing the cell to continue dividing.

Bioenergetic analysis of pancreatic beta-cells shows impaired metabolic signature in type 2 diabetes patients

Impaired activation of mitochondrial energy metabolism in the presence of glucose has been demonstrated in pancreatic beta-cells from patients with type 2 diabetes. The cause of this dysfunction has been unknown. Publishing online in Endocrinology, Buck Institute assistant research professor Akos Gerencser, PhD, shows that in patients with type 2 diabetes the balance between supply and demand of the mitochondrial membrane potential (ΔψM) is altered causing a decrease in the signaling that turns on insulin secretion.

New approach to imaging glucose uptake activity in single living cells

Researchers at Columbia University have reported a new approach to visualize glucose uptake activity in single living cells by light microscopy with minimum disturbance. In a recent study published in Angewandte Chemie International Edition, Associate Professor of Chemistry Wei Min's team developed a new glucose analogue that can mimic the natural glucose, and imaged its uptake as energy source by living cancer cells, neurons and tissues at the single cell level.

Virginia Tech scientist uses mathematical model to show how bacteria can control behavior of robots

Forget the Vulcan mind-meld of the Star Trek generation -- as far as mind control techniques go, bacteria is the next frontier. In a paper published July 16 in Scientific Reports, which is part of the Nature Publishing Group, a Virginia Tech scientist used a mathematical model to demonstrate that bacteria can control the behavior of an inanimate device like a robot.

University of Twente scientists take significant step in breast cancer research

Scientists at the research Institute MIRA at the University of Twente have been working for some time on a new technique to detect breast cancer. The technique based on the physical principle of photoacoustics, has been christened PAMmography. It uses short bursts of light that cause ultrasonic waves to be generated in places with high density of blood vessels, such as in the vicinity of malignant tumours.

Imaging technique could help in diagnosis of atherosclerosis in at-risk patients

Researchers at the University of Cambridge, in collaboration with the University of Edinburgh, have shown how a radioactive agent developed in the 1960s to detect bone cancer can be re-purposed to highlight the build-up of unstable calcium deposits in arteries, a process that can cause heart attack and stroke.
