Research team uses melanin to make biodegradable battery anode
Methane-decomposing bacteria from hot springs need the valuable metals to produce energy
Rare earths are among the most precious raw materials of all. These metals are used in mobile telephones, display screens and computers. And they are apparently indispensable for some organisms as well. A ...
Seemingly competitive co-catalysts cooperate to accelerate chemical reaction
A new, computationally-inspired approach has led a team of Boston College chemists to re-conceptualize a highly valued catalytic process, dramatically increasing the efficiency of a chemical transformation that selectively ...
Researchers ID proteins key in stem cell production
A team of Toronto-based researchers may be one step closer to a 'recipe' for large-scale production of stem cells for use in research and therapy.
Carbon nanotubes for molecular magnetic resonances
Researchers at ICFO have developed a new technique for measuring very weak forces on a molecular scale. Thanks to the use of carbon nanotubes, they have achieved the highest level of sensitivity to date. These results published ...
Rare tree provides key to greener chemistry
(Phys.org) —A rare tree found in Malaysia and Borneo holds the secret to greener chemical production, according to researchers from the Research School of Chemistry.
Motorola on authentication: We're talking tattoos and pills
Researcher admits mistakes in stem cell study
A blockbuster study in which US researchers reported that they had turned human skin cells into embryonic stem cells contained errors, its lead author has acknowledged. ...
Nanotechnology could help fight diabetes: Injectable nanogel can monitor blood-sugar levels, secrete insulin when needed
Injectable nanoparticles developed at MIT may someday eliminate the need for patients with Type 1 diabetes to constantly monitor their blood-sugar levels and inject themselves with insulin.
Discovery may explain how prion diseases spread between different types of animals
Medical researchers at the University of Alberta have made a discovery that may explain how prion diseases, like chronic wasting disease and mad cow disease, adapt in order to spread between various types of animals.
Antigen-encapsulated chitosan particles improve immune response, study finds
(Phys.org) —Biomedical engineering researchers at the University of Arkansas have encapsulated two types of protein antigens in chitosan and demonstrated that the combined material enables or improves three ...
Models move from brain to rain
(Phys.org)—One of climate scientists' key ambitions is to predict future climate change more accurately. They create incredibly detailed computer models, but even these cannot calculate all the infinite ...
Capturing circulating cancer cells could provide insights into how disease spreads
A glass plate with a nanoscale roughness could be a simple way for scientists to capture and study the circulating tumor cells that carry cancer around the body through the bloodstream.
Sticky paper offers cheap, easy solution for paper-based diagnostics
(Phys.org)—A current focus in global health research is to make medical tests that are not just cheap, but virtually free. One such strategy is to start with paper – one of humanity's oldest technologies ...
