Protein recycling machine visualized

Howard Hughes Medical Institute (HHMI) scientists have new structures of an essential cellular recycling machine that depict its structure with near atomic-level detail. The structures, which show a protein called NSF alone ...

Laser pulses reveal DNA repair mechanisms

A new straightforward method enables monitoring the response of nuclear proteins to DNA damage in time and space. The approach is based on nonlinear photoperturbation.

Biologists produce rainbow-colored algae

What can green algae do for science if they weren't, well, green? That's the question biologists at UC San Diego sought to answer when they engineered a green alga used commonly in laboratories, Chlamydomonas reinhardtii, ...

Virology: A marker for a cancer-causing virus

(Phys.org)—Depending on the strain, or genotype, of the human papillomavirus (HPV) (see image), the lesions it causes can range from relatively benign to cancer-causing. Differentiating between lesions caused by low-risk ...

Slow-release 'jelly' delivers peptide drugs better

Duke University biomedical engineers have developed a new delivery system that overcomes the shortcomings of a promising class of peptide drugs – very small proteins – for treating diseases such as diabetes and cancer.

Driving membrane curvature

(Phys.org) -- In biological systems, membranes are as important as water. They form the barrier between the inner world, within our cells, where we perform the chemical reactions of life, and the outside environment.

Membrane fusion a mystery no more

The many factors that contribute to how cells communicate and function at the most basic level are still not fully understood, but researchers at Baylor College of Medicine have uncovered a mechanism that helps explain how ...

Research team achieves first 2-color STED microscopy of living cells

Researchers are able to achieve extremely high-resolution microscopy through a process known as stimulated emission depletion (STED) microscopy. This cutting-edge imaging system has pushed the performance of microscopes significantly ...
