That’s not all.
Here are the stories:
A team led by paleontologist Julia Clarke unearthed the first extinct penguin with preserved evidence of scales and feathers. The 36-million-year-old fossil from Peru shows the new giant penguin’s feathers were reddish brown and grey, distinct from the black tuxedoed look of living penguins.
“We found that sleep-deprived honey bees also experienced communication problems (as humans do),” said Dr. Barrett Klein, the lead researcher on the project. “They advertised the direction to a food site less precisely to their fellow bees.”
The source of HIV infection in two separate criminal cases in which men were convicted of intentionally infecting their female sexual partners was confirmed by scientists from The University of Texas at Austin and Baylor College of Medicine using evolutionary forensics.Electron Interaction Between Molecules Points Way to New High-Powered Organic Batteries
Chemists discovered a new way to pass electrons back and forth between two molecules and that could brighten the path to development of new organic batteries — lightweight energy storage devices that work without the need for toxic heavy metals.
As more women wait until their 30s and 40s to have children, they are more willing to engage in a variety of sexual activities to capitalize on their remaining childbearing years, according to psychologists. Such “reproduction expediting” includes one-night stands and adventurous bedroom behavior, the research shows.New Fossil Suggests Dinosaurs Not So Fierce After All
A new species of dinosaur discovered in Arizona suggests dinosaurs did not spread throughout the world by overpowering other species, but by taking advantage of a natural catastrophe that wiped out their competitors. Sarahsaurus lived about 190 million years ago. It was 14 feet long and weighed about 250 pounds.New Supercomputing Model Enables Breakthrough Findings in Plate Tectonics
Researchers at The University of Texas at Austin and California Institute of Technology developed a new supercomputer model that for the first time produces an unprecedented view of plate tectonics and the forces that drive it.
Geologists studying the Jan. 12 Haiti earthquake say the risk of destructive tsunamis is higher than expected in places such as Kingston, Istanbul and Los Angeles. These cities lie near a coast and near an active geologic feature where two tectonic plates slide past each other.
A team of students designed and built two satellites that were launched Nov. 19. It’s the first student-developed mission in which satellites will orbit and communicate with each other in real-time. Check the mission’s Facebook page, http://www.facebook.com/fastracsats#!/fastracsats?v=wall
