Seeing the universe through new lenses

Like crystal balls for the universe's deeper mysteries, galaxies and other massive space objects can serve as lenses to more distant objects and phenomena along the same path, bending light in revelatory ways.

The mass of the universe

Bochum cosmologists headed by Professor Hendrik Hildebrandt have gained new insights into the density and structure of matter in the universe. Several years ago, Hildebrandt had already been involved in a research consortium ...

Dark matter and massive galaxies

About 85% of the matter in the universe is in the form of dark matter, whose nature remains a mystery, and the rest is of the kind found in atoms. Dark matter exhibits gravity but otherwise does not interact with normal matter, ...

Researchers create focus-free camera with new flat lens

Using a single lens that is about one-thousandth of an inch thick, researchers have created a camera that does not require focusing. The technology offers considerable benefits over traditional cameras such as the ones in ...

High-tech contact lenses correct color blindness

Researchers have incorporated ultra-thin optical devices known as metasurfaces into off-the-shelf contact lenses to correct deuteranomaly, a form of red-green color blindness. The new customizable contact lens could offer ...

Improving adhesives for wearable sensors

By conveniently and painlessly collecting data, wearable sensors create many new possibilities for keeping tabs on the body. In order to work, these devices need to stay next to the skin. In a study described in ACS Omega, ...

Self-moisturizing smart contact lenses

Researchers at Tohoku University have developed a new type of smart contact lenses that can prevent dry eyes. The self-moisturizing system, which is described in the journal Advanced Materials Technologies, maintains a layer ...

Taking the temperature of dark matter

Warm, cold, just right? Physicists at the University of California, Davis are taking the temperature of dark matter, the mysterious substance that makes up about a quarter of our universe.
