What is Nothing?

Is there any place in the Universe where there's truly nothing? Consider the gaps between stars and galaxies? Or the gaps between atoms? What are the properties of nothing?

NASA Picks Top Earth Data Challenge Ideas, Opens Call for Climate Apps

NASA has selected four ideas from the public for innovative uses of climate projections and Earth-observing satellite data.

On the hunt for dark matter

New University of Adelaide Future Fellow Dr Martin White is starting a research project that has the potential to redirect the experiments of thousands of physicists around the world who are trying to identify the nature of dark matter.

Breakthrough in imaging gold nanoparticles to atomic resolution by electron microscopy

Nanometer-scale gold particles are intensively investigated for application as catalysts, sensors, drug delivery devices, biological contrast agents and components in photonics and molecular electronics. Gaining knowledge of their atomic-scale structures, fundamental for understanding physical and chemical properties, has been challenging. Now, researchers at have demonstrated that high-resolution electron microscopy can be used to reveal a three-dimensional structure in which all gold atoms are observed.

Researchers find first direct evidence of 'spin symmetry' in atoms

Just as diamonds with perfect symmetry may be unusually brilliant jewels, the quantum world has a symmetrical splendor of high scientific value.

Water window imaging opportunity

Ever heard of the water window? It consists of radiations in the 3.3 to 4.4 nanometre range, which are not absorbed by the water in biological tissues. New theoretical findings show that it is possible to develop coherent radiations within the water window. These could be the basis of an optimal technique to obtain a high-contrast image of the biological samples or to be used in high-precision spectroscopy.

World's coolest molecules

It's official. Yale physicists have chilled the world's coolest molecules.

Laser device may end pin pricks, improve quality of life for diabetics

Researchers have developed a way to use a laser to measure people's blood sugar, and, with more work to shrink the laser system to a portable size, the technique could allow diabetics to check their condition without pricking themselves to draw blood. In a new article, the researchers describe how they measured blood sugar by directing their specialized laser at a person's palm.
