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)

‘Quantum Bounce’ theory claims black holes explode

Kepler’s Supernova Remnant “On October 9, 1604, sky watchers — including astronomer Johannes Kepler, spotted a “new star” in the western sky, rivaling the brilliance of nearby planets. “Kepler’s supernova” was the last exploding supernova seen in our Milky Way galaxy.
