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)

Physicists attempt quantum clean-up experiment to right old error

Indian physicists propose a tabletop experiment that will provide scientists their first opportunity to measure the probability that particles can move through slits in a twisted path, depicted by the purple ray. (Credit: Aninda Sinha and Urbasi Sinha)

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.

First indirect evidence of undetected strange Baryons

CDF physicist Petar Maksimovic, professor at Johns Hopkins University, presented the discovery to the particle physics community at Fermilab. He explained that the two types of Sigma-sub-b particles are produced in two different spin combinations, J=1/2 and J=3/2, representing a ground state and an excited state, as predicted by theory.

Scientific error delayed the search for alien life

Scientists of the early 20th century argued that tidal forces had caused the sun to spit out the planets when a rogue star passed too close. It was a kind of drive-by shooting theory of planetary formation known as the "Planetesimal Hypothesis." (Credit: NASA, M. Strauss) — Scientists of the early 20th century argued that tidal forces had caused the sun to spit out the planets when a rogue star passed too close.

Scientists unveil new technology to better understand small clusters of atoms

An illustration of the extent to which the atoms, in a small cluster of atoms, vibrate. The spheres represent the range of motion of the atoms, rather than the atoms themselves – the spheres have been exaggerated in size by 45 times in order to ease visualisation. The atoms on the surface have larger ranges of motion than those in the middle of the cluster. (Credit: University of York)

NASA will basically play SimAnt with new “Swarmies” robots

NASA engineers have built four robots nicknamed “Swarmies” to test whether a group of robots can autonomously and effectively scout an area for resources, and they’ve model the software design after how ants do the same thing. (Credit: NASA/D. Gerondidakis, G. Tickle)

Recycling old batteries into solar cells

This could be a classic win-win solution: A system proposed by researchers at MIT recycles materials from discarded car batteries—a potential source of lead pollution—into new, long-lasting solar panels that provide emissions-free power. (Credit: Christine Daniloff/MIT)
