The electric slide dance of DNA knots

DNA has the nasty habit of getting tangled and forming knots. Scientists study these knots to understand their function and learn how to disentangle them. Researchers have now devised and tested a method based on the application of electric fields and optical tweezers.

Microscopy charges ahead

Polarization charges in ferroelectric materials are screened by equal amounts of surface charges with opposite polarity under ambient conditions. Researchers have shown that scraping, collecting, and quantifying surface screen charges reveals the underlying polarization domain structure at high speed, a technique dubbed charge gradient microscopy (CGM).

Quantum leap in lasers brightens future for quantum computing

Scientists have devised a breakthrough laser that uses a single artificial atom to generate and emit particles of light. The laser may play a crucial role in the development of quantum computers, which are predicted to eventually outperform today's most powerful supercomputers.

New material gives rejected drugs a new chance

More than 80 percent of all drug candidates in the pharma R+D suffer from poor solubility and are therefore rejected early in the drug discovery process. Now Uppsala University researchers show that the new material Upsalite, has great potential for development of new formulations of these rejected drugs.

NSF grant will further research on models of self-assembling systems

The models simulate or mimic complex biological processes, such as evolution, self-replication and immune system behaviors, and the formation of prions, protein particles that may cause brain diseases. The models can be used to help scientists develop artificial self-assembling systems in laboratories and will make valuable contributions to the theoretical understanding of biological systems.
