A University of Cincinnati cancer biology team reports breakthrough findings about specific cellular mechanisms that may help overcome endocrine (hormone) therapy-resistance in patients with estrogen-positive breast cancers, combating a widespread problem in effective medical management of the disease.
At the Electronica 2012 trade fair, Fraunhofer researchers will present a printed thermogenerator, which in the future will be able to generate energy supply for sensors through temperature differences.
The Vienna research team led by Anton Zeilinger has achieved a new milestone in the history of quantum physics: The scientists were able to generate and measure the entanglement of the largest quantum numbers to date.
Scientists have found through spectroscopic investigations on a hydrogen-producing enzyme that the environment of the catalytic site acts as an electron reservoir in the enzyme. Thus, it can very efficiently produce hydrogen, which has great potential as a renewable energy source.
The use of nanomaterials in agriculture could, on the one hand, reduce cost and effort, increase efficiency and lead to more environmentally sound applications. On the other hand, it might also have a negative effect on microorganisms in the soil.
A research team at the National Institute of Standards and Technology (NIST) has developed a model for making quantifiable predictions of how a group of cells will react and change in response to a given environment or stimulus - and how quickly.
A new discovery by University of Oklahoma and North Carolina State University researchers shows a breakthrough in speeding up the process for synthesizing transition metal oxide nanostructures. What had once taken days can now be accomplished instantaneously.
A team of scientists from the MESA+ Institute for Nanotechnology at the University of Twente, the FOM Institute AMOLF in Amsterdam, and the Technical University of Denmark in Lyngby, has settled a long-standing scientific debate whether the energy transfer between two molecules can be controlled via the nearby environment or not. Their research shows that the energy transfer efficiency can indeed be controlled via the nearby environment.
A new type of nanoscale molecular trap makes it possible for industry to store large amounts of hydrogen in small fuel cells or capture, compact and remove volatile radioactive gas from spent nuclear fuel in an affordable, easily commercialized way.
Researchers from the NIST Center for Nanoscale Science and Technology and Arizona State University have used an environmental scanning transmission electron microscope (ESTEM) to control the size and placement of iron nanoparticles in order to catalyze the growth of carbon nanotubes on a silicon oxide substrate.
Silver nanoparticles can have a severe environmental impact if their utilisation in clothing continues to increase. If everyone buys one silver nanoparticle-treated sock a year, the silver concentration in waste water treatment plant sludge can double.
