Undergraduates develop 'dirt-powered' microbial fuel cells to light Africa

CAMBRIDGE, Mass. – May 14, 2008 – A team composed of Harvard students and alumni was among the winners of the World Bank’s Lighting Africa 2008 Development Marketplace competition, held in Accra, Ghana from May 6 to 8, 2008. The innovation, microbial fuel cell-based lighting systems suitable for Sub-Saharan Africa, netted the group a $200,000 prize.

Canon Patents New Camera Fuel Cell

canon-bge4.jpgCanon may be planning to bring fuel cells to DSLRs. A new patent application details a clever workaround for the problems of supplying fluctuating current from the cells. Instead of just one fuel cell, or a bank working together, Canon's design works more like an inkjet printer: several fuel cells output differing voltages, and these can be mixed and matched. Thus, high-draw operations like mirror-flipping or flash charging can be given the juice they need.

Embryonic Pathway Delivers Stem Cell Traits

Cells that undergo an epithelial-to-mesenchymal transition (EMT) show properties of stem cells, including the ability to self-renew. In addition, stem cells exhibit properties of cells that undergo EMT. Strikingly, both normal and cancer stem cells can be generated from differentiated cells by EMT. Understanding the role of EMT in adult stem cell creation may lead toward the development of healthy stem cells for regenerative medicine and provide drug targets for cancer.

Nanostructures absorb light from all directions

More efficient light absorbing materials on the microscale are needed for a variety of technology applications, such as optical interconnects, light-emitting sources and shields for micro-optical devices. In particular, materials that absorb light from all directions are required, which are not easy to make. Now, researchers in Spain have shown that they can achieve total omnidirectional light absorption in nanostructured metal surfaces that contain localized optical excitations called plasmons. What's more, the effect can be seen over the full range of incident angles and can be tuned throughout the visible and near-infrared regions. Such surfaces could also be crucial for making solar cells.

Researchers Modify T-Cells, Make Them HIV Resistant

DieNadel writes to share that naturally occurring proteins called "zinc fingers" are being used in a new approach to AIDS treatment. Using modified T-Cells with the zinc fingers, researchers at the Pennsylvania School of Medicine have shown a reduction in viral load in mice. "'By inducing mutations in the CCR5 gene using zinc finger proteins, we've reduced the expression of CCR5 surface proteins on T cells, which is necessary for the AIDS virus to enter these immune system cells,' explains first author Elena Perez, MD, PhD, Assistant Professor of Pediatrics at Penn. 'This approach stops the AIDS virus from entering the T cells because it now has an introduced error into the CCR5 gene.'"

Infrared-heated nanotubes seek out cancer cells, torch them

The war on cancer has a new secret weapon: carbon nanotubes heated up via near-infrared light, scorching the cancerous cells inside the body. Developed by scientists at the University of Texas Southwestern Medical Center, the nanotubes are stronger than steel and can be attached to an antibody that seeks out cancer cells and bind to them. At that point, the near-infrared light is beamed in, heating the tubes up until the cancer is roasted.

Fuel Cells 2000 announced today that it has launched the Fuel Cell Insider blog (www.fuelcellinsider.org), a new web log devoted entirely to fuel cells and related fuels.

Fighting the fuel poverty challenge (Fuel for Thought blog)

Campaigners against rising fuel prices plunging more and more UK energy consumers into fuel poverty -- the condition in which more than 10% of take-home pay is spent on cooking and keeping warm -- go before UK members of parliament Thursday June 5 to give their views on the latest government proposals to help. But will they be able to implement new measures fast enough to make a difference this winter?

Patent App Sheds Light on Solar-Powered iPod

A reported Apple patent application suggests the company is working on a way to make iPods and iPhones run on solar energy. Photo cells could be integrated with the device's LCD screen, allowing the unit to collect power from the sun. Such cells would be sandwiched in with the touch screen on an iPhone, for instance.

Nanotechnology, Biomolecules, and Light Unite to "Cook" Cancer Cells

Using carbon nanotubes linked to tumor-homing antibodies, a research team headed by Ellen Vitetta, Ph.D., M.D., of the University of Texas Southwestern Medical Center has shown that they can specifically kill the targeted tumor cells using near-infrared light. This work appears in the Proceedings of the National Academy of Sciences.
