CHALK TALK: MITOCHONDRIA

submitted by: nsf

This episode of Chalk Talk gives viewers a look inside the "power plant" of most complex cells. Mitochondria provide energy for cells to move, divide, and do all the things they need to do to function properly. Mitochondria are found within almost all living organisms with complex cell structures.

GREEN REVOLUTION: MICROBES

submitted by: nsf
In Bruce Logan's lab at Penn State Univeristy, researchers are working on developing microbial fuel cells (MFC) that can generate electricity I while accomplishing wastewater treatment. In a project supported by NSF, they are researching methods to increase power generation from MFCs while at the same time recovering more of the energy as electricity. Through their research projects, Logan’s team has already proven that they can produce electricity from ordinary domestic wastewater, as...

GREEN REVOLUTION: DISCOVER

submitted by: nsf
A trip to Snowy River, a bright white crystalline formation found deep within Fort Stanton Cave in New Mexico, reveals a lot about life and energy in unexpected places. Host Lisa Van Pay meets Diana Northup and Monica Moya, researchers who study life in caves. As they explore the cave they ask questions, think of possible answers and ways to test them, and discuss how to share their findings with the community. Together, science and engineering have resulted in advancements that have changed...

Staphylococcus aureus phenotype switching: an effective bacterial strategy to escape host immune response and establish a chronic infection

submitted by: Ben_Norman
Staphylococcus aureus is a frequent cause for serious, chronic and therapy-refractive infections in spite of susceptibility to antibiotics in vitro. In chronic infections, altered bacterial phenotypes, such as small colony variants (SCVs), have been found. Yet, it is largely unclear whether the ability to interconvert from the wild-type to the SCV phenotype is only a rare clinical and/or just laboratory phenomenon or is essential to sustain an infection. Here, we performed different...
