Researchers have shown that spherical nucleic acids (SNAs) can be used as potent drugs to effectively train the immune system to fight disease, by either boosting or dampening the immune response. The initial treatment triggers a cell-specific immune response all over the body.

Molecular ruler sets bacterial needle length
A step in understanding how microbes infect target cells. The findings have potential long-term applications for developing new antibiotics against salmonella and certain other disease-causing bacteria, for designing bacteria that could inject cancer cells with chemotherapy drugs, and for helping people how to design machines at the nanoscopic or molecular scale.
PETA Science Consortium seeks laboratories to develop nanomaterial toxicity test
Today, the PETA International Science Consortium put out a request for proposals to identify facilities that can develop an in vitro test that, when used in an integrated approach, has the potential to replace the current test conducted on animals to assess the inhalation toxicity of nanomaterials.
Metal-organic framework destroys common toxic nerve agents quickly
Scientists have developed a robust new material, inspired by biological catalysts, that is extraordinarily effective at destroying toxic nerve agents that are a threat around the globe.
Antibiotic nanoparticles attack respiratory infection
Researchers have shown that the use of nanoparticles to carry antibiotics across biological barriers can be effective in treating lung infections. Doing so allows better delivery of the drug to the site of infection, and hence prevents the development of antibiotic resistance which may be caused by too large and continued doses of antibiotic.
Scientists move closer to 'two for one deal' on solar cell efficiency
The causes of a hitherto mysterious process that could enhance the power of solar cells have been explained in a new study.
Symmetry matters in graphene growth
What lies beneath growing islands of graphene is important to its properties, according to a new study.
A new method for making perovskite solar cells
The new method involves a room-temperature solvent bath to create perovskite crystals, rather than the blast of heat used in current crystallization methods.
Optimized storage principle and new material increase lithium storage density in batteries
Researchers have developed a new cathode material based on a new storage principle, as a result of which energy storage densities can be increased beyond those of systems known so far.
Nano piano's lullaby could mean storage breakthrough
Researchers have demonstrated the first-ever recording of optically encoded audio onto a non-magnetic plasmonic nanostructure, opening the door to multiple uses in informational processing and archival storage.
Fully automated single molecule measurements probe complex biological networks in living cells
The new approach allows scientists for the first time to follow the protein networks that drive a biological process in real time.
New remote control for molecular motors
In the eyes of physicists, magnetic molecules can be considered as nanoscale magnets. Remotely controlling the direction in which they rotate, like spinning tops, may intuitively be difficult to achieve. However, physicists have just demonstrated that it is theoretically possible to do so.
Design maps predict strength of structures (w/video)
Mother-of-pearl, the iridescent layer in the shells of some mollusks, inspired a study that will help scientists and engineers judge the ultimate strength, stiffness and toughness of composite materials for anything from nanoscale electronics to buildings.
How geckos manage to stay clean, even in dusty deserts
A team of scientists has discovered how geckos manage to stay clean, even in dusty deserts. The process may also turn out to have important human applications.
Research proves single wall carbon nanotubes capable of significantly improving elastomer properties
Recent results have demonstrated the positive impact single wall carbon nanotubes can make to the physical, mechanical and chemical indexes of elastomer composites.
Parallel scanning probe microscope beats single scanning 1000 fold
A multiple miniaturized Scanning Probe Microscopy (MSPM) heads system, which can inspect and measure many sites in parallel, means an enhancement of throughput in order of more than 1000 times the single SPM throughput.
Developing a photocatalytic raector to treat agricultural wastewaters
The PCATDES project, which aims to developed a photo-catalytic reactor capable of improving the current treatment of waste water generated by agricultural industries and fisheries, has reached its mid-point.
