NASA establishes contact with STEREO mission

more »
NASA has reestablished contact with its STEREO-B spacecraft, after communications were lost on Oct. 1, 2014. Over 22 months, the STEREO team has worked to attempt contact with the spacecraft. Most recently, they have attempted a monthly recovery operation using NASA's Deep Space Network, which tracks and communicates with missions throughout space.

Fossilized rivers suggest warm, wet ancient Mars

more »
Extensive systems of fossilized riverbeds have been discovered on an ancient region of the Martian surface, supporting the idea that the now cold and dry Red Planet had a warm and wet climate about 4 billion years ago, according to new research.

Nanofiber scaffolds demonstrate new features in the behavior of stem and cancer cells

more »
A discovery in the field of biomaterials may open new frontiers in stem and cancer cell manipulation and associated advanced therapy development. Novel scaffolds are shown enabling cells to behave in a different but controlled way in vitro due to the presence of aligned, self-assembled ceramic nanofibers of an ultra-high anisotropy ratio augmented into graphene shells.

Stretchy supercapacitors power wearable electronics

more »
A future of soft robots or smart T-shirts may depend on the development of stretchy power sources. But traditional batteries are thick and rigid -- not ideal properties for materials that would be used in tiny malleable devices. In a step toward wearable electronics, a team of researchers has produced a stretchy micro-supercapacitor using ribbons of graphene.
