Quantum computer coding in silicon now possible

A team of Australian engineers has proven—with the highest score ever obtained—that a quantum version of computer code can be written, and manipulated, using two quantum bits in a silicon microchip. The advance removes ...

Researchers build nanoscale autonomous walking machine from DNA

Researchers at The University of Texas at Austin have developed a nanoscale machine made of DNA that can randomly walk in any direction across bumpy surfaces. Future applications of such a DNA walker might include a cancer ...

Cells get noisy in crowded environments

Bacteria are incredibly small, yet pack an enormous diversity of different molecules such as DNA, mRNA and proteins. Chemists from Radboud University Nijmegen, Eindhoven and Paris now show for the first time that random variations ...

Nanotechnology inspires next-generation dental materials

Have a cavity? Ask your dentist about filling it with a mixture of nanoparticles including silica and zirconia. These white fillings (known as nano-composite resins) resemble teeth better than their metal alternatives and ...

Graphene supercurrents go ballistic

Researchers with Europe's Graphene Flagship have demonstrated superconducting electric currents in the two-dimensional material graphene that bounce between sheet edges without scattering. This first direct observation of ...

Project uses crowd computing to improve water filtration

Nearly 800 million people worldwide don't have access to safe drinking water, and some 2.5 billion people live in precariously unsanitary conditions, according to the Centers for Disease Control and Prevention. Together, ...

Varying the sliding properties of atoms on a surface

It's possible to vary (even dramatically) the sliding properties of atoms on a surface by changing the size and "compression" of their aggregates: an experimental and theoretical study conducted with the collaboration of ...
