Pairing Quantum Dots with Fullerenes for Nanoscale Photovoltaics (replacing myself because blogger.com is too slow to fix)

Left: Photoinduced electron transfer occurring in quantum dot-bridge-fullerene hererodimers and observed with single molecule microscopy. Right: Control of electron transfer (ET) rate by variation of interparticle distance (R, upper panel) and quantum dot size (D, lower panel). Brookhaven National Laboratory researchers have assembled nanoscale pairings of particles that show promise as miniaturized power sources. Composed …

Pentagon funded Aeros working on Rigid Aeroshell Cargo Airship

In 2012-13, Aeros plans to fly the Pelican, a 230-ft.-long, 600,000-cu.-ft. demonstrator for its rigid-aeroshell, variable-buoyancy (RAVB) technology. Inside the shell, comprising a load-bearing frame of carbon-fiber trusses covered by thin-gauge rigid panels, will be a membrane to contain the helium lifting gas. Inside that membrane will be pressurized pump-fed tanks. More helium under pressure …

Absence of Mitochondrial Translation Control Proteins Extends Life Span by Activating Sirtuin-Dependent Silencing

A SOV1 Deletion Extends Life Span without Affecting Steady-State Levels of ROS or Oxidative Damage Mitochondria are the body’s energy producers, the power stations inside our cells. Researchers at the University of Gothenburg, Sweden, have now identified a group of mitochondrial proteins, the absence of which allows other protein groups to stabilise the genome. This …

A donated blood vessel had a patients own stem cells infused for rejection free transplant surgery

For the first time ever in the world, researchers at the Sahlgrenska Academy have produced a blood vessel from stem cells and then used it in an operation on a 10-year-old girl at the Sahlgrenska University Hospital. Surgeon and Professor Michael Olausson was able to create a new connection with the aid of this blood …

Interleuken-12 primed T-Cells more effective in fighting cancer

Researchers with UCLA’s Jonsson Comprehensive Cancer Center have discovered a way to amp up the power of killer T-cells, called CD8 cells, making them more functional for longer periods of time and boosting their ability to multiply and expand within the body to fight melanoma, a new study has found. When they programmed t-cells in …

Effective cancer vaccines will soon emerge – Sander Olson Interviews Dr. Herbert Chow, Ph.D

A protein called Keyhole Limpet Hemocyanin (KLH) could play a key role in treating many different types of cancers. KLH can be used to direct the body to attack the cancer cells, and it also has important applications in immune response testing and immunotoxicology. But the molecule is harvested from a rare mollusk, and is …
