Physicists discover how particles self-assemble

A team of physicists has discovered how DNA molecules self-organize into adhesive patches between particles in response to assembly instructions. Its findings offer a "proof of concept" for an innovative way to produce materials ...

Chocolate physics: How modeling could improve 'mouthfeel'

Lecithin is an ingredient that you've probably never heard of, but one that plays a vital role in the production of chocolate and many other foods. It's never been clear how this ingredient works on a molecular level, and ...

Chemists inhibit a critical gear of cell immortality

One of the hallmarks of cancer is cell immortality. A Northwestern University organic chemist and his team now have developed a promising molecular tool that targets and inhibits one of cell immortality's underlying gears: ...

Gene editing now possible in ticks

Researchers have successfully used CRISPR-Cas9 to edit the genomes of the black-legged tick. To accomplish this feat, they developed an embryo injection protocol that overcame a major barrier in the field. The work appears ...

A greener way to raise cotton and combat nematodes

(Phys.org) -- U.S. Department of Agriculture (USDA) scientists are using molecular tools to help cotton growers cut back on their use of pesticides in controlling one of their worst adversaries: the root-knot nematode (Meloidogyne ...
