Scientists pinpoint one way nanoparticles damage immune cells

Scientists have shown that a process known as oxidative stress is at work during encounters between certain nanoparticles and immune cells, selectively modifying proteins on macrophages, a type of immune cell. The findings, ...

Gasoline from water, CO2 and sunlight

A research team from ETH Zurich, PSI, and Caltech demonstrates the stable, efficient and rapid generation of solar fuels. They apply a thermochemical cycle based on ceria redox reactions to thermochemically split water and ...

Novel approach improves graphene-based supercapacitors

Demand for integrated energy storage devices is growing rapidly as people rely more and more on portable and wireless electronics, and the global need grows for clean energy sources such as solar and wind energies.

Simulating how the Earth kick-started metabolism

(Phys.org) —Researchers have developed a new approach to simulating the energetic processes that may have led to the emergence of cell metabolism on Earth – a crucial biological function for all living organisms.

A 'sponge' path to better catalysts and energy materials

Scientists from the U.S. Department of Energy (DOE) Office of Science's Oak Ridge (ORNL) and Argonne National Laboratories, Northwestern University, and Hokkaido University (Japan) have developed a new oxygen "sponge" that ...

Unexpected allies help bacteria clean uranium from groundwater

(Phys.org) —Since 2009, SLAC scientist John Bargar has led a team using synchrotron-based X-ray techniques to study bacteria that help clean uranium from groundwater in a process called bioremediation. Their initial goal ...
