Nobel prize winner: Let’s find dark matter and dark energy

This picture shows ALMA antennas pointing towards the centre of the milky-way. (Photo: ESO, B. Tafreshi) — Dark matter and dark energy continue to be cosmological conundrum for physicists worldwide. Nobel prize winner Brian Schmidt offers his perspective in an interview. The image shown here is of the ALMA antennas and the constellations of Carina (The Keel) and Vela (The Sails). The dark, wispy dust clouds of the Milky Way streak from middle top left to middle bottom right. (Credit: ESO, B. Tafreshi)

Pluto and the other dwarf planets could have astrobiological potential

“Our model predicts different fracture patterns on the surface of Charon depending on the thickness of its surface ice, the structure of the moon’s interior and how easily it deforms, and how its orbit evolved,” said Alyssa Rhoden of NASA’s Goddard Space Flight Center. (Credit: NASA)

Soft infrastructure challenges to scientific knowledge discovery

Open network environments have become essential in the sciences, enabling accelerated discovery and communication of knowledge. Yet, the real revolution began when open community databases allowed researchers to build on existing contributions and compare their results to established knowledge. (Credit: King, Uhlir)

An interesting glimpse into how future state of the art electronics might work

. A novel class of electronic materials – the so-called transition-metal oxides – hold promise for exciting, new applications. Where layers of this novel class of electronic materials touch, often a unique, and unprecedented phenomenon occurs: for instance, the interface between two insulators can become superconducting, or a strong magnetic order can build up between two non-magnetic layers.

Atomic clocks on the International Space Station will study time and space

NIST-F1, the nation's primary time and frequency standard, is a cesium fountain atomic clock developed at the NIST laboratories in Boulder, Colorado. NIST-F1 contributes to the international group of atomic clocks that define Coordinated Universal Time (UTC), the official world time. Because NIST-F1 is among the most accurate clocks in the world, it makes UTC more accurate than ever before.

Mercury’s transit: An unusual spot on the sun

What’s that dot on the Sun? If you look closely, it is almost perfectly round. The dot is the result of an unusual type of solar eclipse that occurred in 2006. Usually it is the Earth’s Moon that eclipses the Sun. This time, the planet Mercury took a turn. (Credit: D. Cortner, NASA, K. Schmidt) — What’s that dot on the Sun?

Space’s quantum physics confound scientists

676x380 — Although they are gigantic, ranging from one to a few hundred lightyears in size, the physical process that causes these nebulae to emit their own light (rather than merely reflect light from nearby stars) occurs at the atomic level. It is the same process that makes familiar florescent lights shine here on Earth. (Credit: NASA, Prozesky)

X-ray laser probes tiny quantum tornadoes in superfluid droplets

A patterned 3-D grid of tiny whirlpools, called quantum vortices, populate a nanoscale droplet of superfluid helium. Researchers found that in a micron-sized droplet, the density of vortices was 100,000 times greater than in any previous experiment on superfluids. An artistic rendering of a wheel-shaped droplet can be seen in the distance. (Credit: SLAC National Accelerator Laboratory)
