Our Solar System: Rare Species In Cosmic Zoo 197

Posted by samzenpus
from the best-in-class dept.
astroengine writes "Pulling from 20 years of research since the first discoveries of planets beyond our solar system, scientists have concluded that Earth and its sibling worlds comprise what appears to be a relatively rare breed in a diverse cosmic zoo that includes a huge variety of planet sizes, orbits and parent stars. The most common systems contain one or more planets one to three times bigger than Earth, all orbiting much closer to their parent stars than Earth circles the sun, says astronomer Andrew Howard, with the University of Hawaii."

Repeal of Louisiana Science Education Act Rejected 318

Posted by samzenpus
from the teach-whatever-you-want dept.
egjertse writes "A Louisiana law that opponents say leaves the backdoor open to teaching 'creationism' in public schools will stay on the books after a Senate committee Wednesday effectively killed a bill that would repeal the statute. After hours of testimony for and against House Bill 26, which repeals the 2008 Louisiana Science Education Act, the senators narrowly deferred the legislation, effectively killing it in committee. The bill was sponsored by Sen. Karen Carter Peterson, D-New Orleans."

IBM Researchers Open Source Homomorphic Crypto Library 130

mikejuk writes with news of an advancement for homomorphic encryption and open source: "To be fully homomorphic the code has to be such that a third party can add and multiply numbers that it contains without needing to decrypt it. In other words they can change the data by working with just the encrypted version. This may sound like magic but a fully homomorphic scheme was invented in 2009 by Craig Gentry. This was a step in the right direction but the problem was that it is very inefficient and computationally intensive. Since then there have been a number of improvements that make the scheme practical in the right situations Now Victor Shoup and Shai Halevi of the IBM T J Watson Research Center have released an open source (GPL) C++ library, HElib, as a Github project. The code is said to incorporate many optimizations to make the encryption run faster. Homomorphic encryption has the potential to revolutionize security by allowing operations on data without the need to decrypt it."

Florida Teen Expelled and Arrested For Science Experiment 1078

Posted by timothy
from the government-schooling dept.
First time accepted submitter ruhri writes "A 16 year-old girl in Florida not only has been expelled from her high school but also is being charged as an adult with a felony after replicating the classic toilet-bowl cleaner and aluminum foil experiment. This has quite a number of scientists and science educators up in arms. The fact that she's African American and that the same assistant state attorney has decided not to charge a white teenager who accidentally killed his brother with a BB gun has some thinking whether this is a case of doing science while black."

New Camera Inspired By Insect Eyes 35

from the looking-at-the-world-through-fly's-eyes dept.
sciencehabit writes "An insect's compound eye is an engineering marvel: high resolution, wide field of view, and incredible sensitivity to motion, all in a compact package. Now, a new digital camera provides the best-ever imitation of a bug's vision, using new optical materials and techniques. This technology could someday give patrolling surveillance drones the same exquisite vision as a dragonfly on the hunt."
