Linker histone's surprising partnership with single-stranded DNA

To keep order in the tight quarters of the cell nucleus, our DNA is neatly clamped in place around a central disk by H1 linker histone, which helps shepherd DNA into the tidy chromatin fibers that comprise chromosomes. Linker ...

Two teams use neutral atoms to create quantum circuits

Two teams of researchers working independently have shown the viability of using neutral atoms to create quantum circuits—both have published outlines of their work in the journal Nature. One of the groups, with members ...

Octopus-like tentacles help cancer cells invade the body

With help from the best tweezers in the world, a team of researchers from the University of Copenhagen has shed new light on a fundamental mechanism in all living cells that helps them explore their surroundings and even ...

New advances in protein-folding process thermodynamics

In biophysics, the kinetic states of molecules play a determining role in the metabolic and physiological processes in which they take part. Now, a paper published in the journal Proceedings of the National Academy of Sciences ...

A new method for quantum computing

Physicists from the University of Amsterdam have proposed a new architecture for a scalable quantum computer. Making use of the collective motion of the constituent particles, they were able to construct new building blocks ...

When light loses symmetry, it can hold particles

Optical tweezers use light to immobilize microscopic particles as small as a single atom in 3D space. The basic principle behind optical tweezers is the momentum transfer between light and the object being held. Analogous ...
