- Meteor that hit Russia came from Apollo asteroid family
The meteor that recently broke up over Chelyabinsk, Russia came from the Apollo class of near-Earth asteroids, researchers from the University of Antioquia in Colombia say. At 55-foot wide, scientists say the meteor was too small to be detected by sky surveys and its approach would have been blocked by the sun. Before the meteor hit, a NASA group led by Lindley Johnson had been recommending the setup of an international asteroid-warning network to watch for more near-Earth objects. Discovery

- Robotic bat wing could aid in developing aircraft
Brown University scientists say they have built a robotic bat wing that could lead to the development of a flapping aircraft. The 8-inch wing is based on the lesser dog-faced fruit bat. "A bird has three wing joints at the shoulder, elbow and wrist. Bats also have several joints within each of the fingers, providing up to 25 joints in the wing, all of which allow it to change the shape of the wing dramatically, for more maneuverability and fine control over flight," said researcher Joseph Bahlman.

- Hubble's Milky Way photos reveal a cannibal galaxy
Photos from the Hubble Space Telescope show that the Milky Way galaxy has grown by cannibalizing smaller galaxies, according to a study. The finding could help astronomers gain a better understanding of how mass in the galaxy is distributed and could also give new insight into dark matter. "By studying the mass distribution, we can see whether it follows the same distribution as predicted in theories of structure formation," said lead author Alis Deason. Space.com

- Archaeologists doubt bones belong to Cleopatra's sister
Researchers are doubting a claim by a Viennese archaeologist who says she has found the bones of Cleopatra's sister Arsinoe IV. Hilke Thur did DNA tests on the remains, but the bones have been contaminated by overhandling, and other evidence is largely circumstantial. Thur remains hopeful that new identification methods may one day prove her theory. LiveScience.com

- Urine test can diagnose "river blindness"
Urine samples may help doctors identify people infected with "river blindness" before they lose their sight. The blindness, found mostly in sub-Saharan African countries, is caused by a parasite that infects humans through black fly bites. Scientists have discovered an unknown molecule in the urine of those infected with the parasite. "Using this molecule, we could make a diagnostic test that can be put in a backpack and diagnose whether people are infected or not," said researcher Daniel Globisch. ScienceMag.org/Science Now blog

- Kan. bill to establish adult stem cell facility moves forward
The Kansas Senate Public Health and Welfare Committee on Tuesday approved legislation that would establish the Midwest Stem Cell Therapy Center at the University of Kansas Medical Center. The facility, intended to become a regional hub for adult stem cell research and treatment, will focus on producing clinical-grade stem cells from adult tissues, cord blood and other such materials. Embryonic stem cells would not be allowed at the facility. The Topeka Capital-Journal (Kan.)

- EPA OKs new biofuel pathways for camelina, others under RFS
The Environmental Protection Agency issued a final rule identifying pathways for biofuels derived from camelina, energy cane and renewable gasoline to qualify as feedstocks and fuels under the Renewable Fuel Standard. Under the pathways, camelina oil could qualify as biomass-based diesel or advanced biofuel, while energy-cane-based biofuel and renewable gasoline derived from certain sources could qualify as cellulosic biofuel.
