Long before the knights of medieval Europe wielded flails or martial artists brandished nunchucks, it appears that a flightless prehistoric bird used its own wings as a similar type of weapon in combat. (more…)
*Collapse of Earth’s marine life 378 to 375 million years ago holds key*
An influx of invasive species can stop the dominant natural process of new species formation and trigger mass extinction events, according to research results published in the journal PLoS ONE.
The study of the collapse of Earth’s marine life 378 to 375 million years ago suggests that the planet’s current ecosystems, which are struggling with biodiversity loss, could meet a similar fate. (more…)
A research article presented by an Israeli team has unearthed new evidence on the history of the human being – namely that Homo sapiens may be far, far older than we imagined. A research team from the University of Tel Aviv has discovered fossilised teeth 400,000 years old. (more…)
Sequencing of ancient DNA reveals new hominin population that is neither Neanderthal nor modern human
Researchers have discovered evidence of a distinct group of “archaic” humans existing outside of Africa more than 30,000 years ago at a time when Neanderthals are thought to have dominated Europe and Asia. But genetic testing shows that members of this new group were not Neanderthals, and they interbred with the ancestors of some modern humans who are alive today. (more…)
A new Mars movie clip gives us a rover’s-eye view of a bluish Martian sunset, while another clip shows the silhouette of the moon Phobos passing in front of the sun.
America’s Mars Exploration Rover Opportunity, carefully guided by researchers with an artistic sense, has recorded images used in the simulated movies.
These holiday treats from the rover’s panoramic camera, or Pancam, offer travel fans a view akin to standing on Mars and watching the sky. (more…)
This season’s annual scientific balloon campaign, which is held by NSF and NASA, will conduct varied experiments using ultra-sophisticated instrumentation.
NASA and the National Science Foundation launched a scientific balloon on Monday, December 20, Eastern Standard time, to study the effects of cosmic rays on Earth. It was the first of five scientific balloons scheduled to launch from Antarctica in December.
The Cosmic Ray Energetics And Mass (CREAM VI) experiment was designed and built at the University of Maryland. CREAM is investigating high-energy cosmic-ray particles that originated from distant supernovae explosions in the Milky Way and reached Earth. Currently, CREAM VI is floating 126,000 ft above Antarctica with nominal science operations. (more…)
Russia is ready to build a nuclear power plant in Egypt at its own expense, to manage the plant, and even find markets for the electricity. Early next year Egypt is expected to announce a tender for the construction of nuclear power plant with the capacity of 1 GW 150 km from Alexandria. Russia’s Rosatom will participate in the tender.
A meeting of Russian-Egyptian intergovernmental commission on trade, economic and scientific-technical cooperation was held on Monday. From the Russian side it was chaired by the Minister of Industry and Trade Viktor Khristenko. (more…)

Washington, D.C.
— Scientists from all over the world are taking a second, more expansive, look at the car-sized asteroid that exploded over Sudan’s Nubian Desert in 2008. Initial research was focused on classifying the meteorite fragments that were collected two to five months after they were strewn across the desert and tracked by NASA’s Near Earth Object astronomical network.
Now in a series of 20 papers for a special double issue of the journal Meteoritics and Planetary Science, published on December 15, researchers have expanded their work to demonstrate the diversity of these fragments, with major implications for the meteorite’s origin. (more…)
