Nanobowls serve up chemotherapy drugs to cancer cells

For decades, scientists have explored the use of liposomes—hollow spheres made of lipid bilayers—to deliver chemotherapy drugs to tumor cells. But drugs can sometimes leak out of liposomes before they reach their destination, ...

What limits the ability of plants to draw water from dry soil?

What limits the ability of plants to draw water from dry soil? That's the question California State University, Fullerton plant biologist H. Jochen Schenk and his collaborators addressed in a study supported by the National ...

Simulations show fundamental interactions inside the cell

Actin filaments have several important functions inside cells. For one, they support the cell membrane by binding to it. However, scientists did not know exactly how the actin interacts with the membrane lipids. Simulations ...

Polymers get caught up in love-hate chemistry of oil and water

Researchers at Oak Ridge National Laboratory and the University of Tennessee achieved a rare look at the inner workings of polymer self-assembly at an oil-water interface to advance materials for neuromorphic computing and ...

Turning a dangerous toxin into a biosensor

Some types of bacteria have the ability to punch holes into other cells and kill them. They do this by releasing specialized proteins called "pore-forming toxins" (PFTs) that latch onto the cell's membrane and form a tube-like ...

Scientists develop DNA microcapsules with built-in ion channels

A Research group led by Tokyo Tech reports a way of constructing DNA-based microcapsules that hold great promise for the development of new functional materials and devices (Figure 1). They showed that tiny pores on the surface ...

Graphene layer enables advance in super-resolution microscopy

Researchers at the University of Göttingen have developed a new method that takes advantage of the unusual properties of graphene to electromagnetically interact with fluorescing (light-emitting) molecules. This method allows ...

Study unravels mystery of antimicrobial frog secretions

Japanese scientists, including researchers at Tokyo University of Agriculture and Technology (TUAT) and Yokohama National University, have identified the molecular mechanism that gives the skin secretions of a species of ...
