Vision changes in space

Understanding the effects of microgravity on the human body is essential in enabling astronauts to travel through the harsh environment of space for months, or even years. Significant changes to the body's skeletal and muscle ...

Remote sensing research improves hurricane response

Safe and uninterrupted road travel is crucial in the aftermath of storms so that people can access medical treatment, downed power lines can be removed and communities can begin a return to normalcy.

Light derails electrons through graphene

The way electrons flow in a material determines its electronic properties. For example, when a voltage is sustained across a conducting material, electrons start flowing, generating an electrical current. These electrons ...

Enhancing the electromechanical behavior of a flexible polymer

Piezoelectric materials convert mechanical stress into electricity, or vice versa, and can be useful in sensors, actuators and many other applications. But implementing piezoelectrics in polymers—materials composed of molecular ...

Magnetism helps electrons vanish in high-temp superconductors

Superconductors—metals in which electricity flows without resistance—hold promise as the defining material of the near future, according to physicist Brad Ramshaw, and are already used in medical imaging machines, drug ...

Quantum imaging: Pushing the boundaries of optics

Quantum mechanically entangled light particles break down the boundaries of conventional optics and allow a glimpse into previously invisible wavelength ranges, thus bringing about new possibilities for imaging techniques, ...

Phosphorescent material inspired by 'glow in the dark' wood

Scientists have harnessed the natural ability of wood to faintly glow to develop a new sustainable phosphorescent material that could potentially be used in a wide number of applications, from medical imaging and optical ...
