Title: Self-tuning and the derivation of the Fab Four Authors: Christos Charmousis, Edmund J. Copeland, Antonio Padilla, Paul M. Saffin We have recently proposed a special class of scalar tensor theories known as the Fab Four. These arose from attempts to analyse the cosmological constant probl...
Title: Variability of the transitional T Tauri star T Chamaeleontis Authors: E. Schisano, E. Covino, J.M. Alcala', M. Esposito, D. Gandolfi, E.W. Guenther (Version v2) We characterise the physical properties of T Chamaeleontis, a transitional T Tauri star showing UX Ori-type variability, and...
Scientists at the National Institute of Standards and Technology (NIST) and Indiana University (IU) have determined the most accurate values ever for a fundamental property of the element lithium using a novel approach that may permit scientists to do the same for other atoms in the periodic tabl...
Canadian scientists named a new species of ancient marine reptile "Ping Pong Ichthyosaur" for the spot where the prehistoric fossil was stored for 25 years.
"It was pretty amazing to realize this valuable discovery had sat under a Ping Pong table for 25 years. But I suppose that after 100 mil...

Asteroid (324) Bamberga is one of the largest asteroids in the Main asteroid belt. It was discovered by Johann Palisa on February 25, 1892 in Vienna, making it one of the last large (diameter over 200 km) asteroids discovered. Apart from the near-earth asteroid Eros, it was the last asteroid which is...
A 500-pound space rock about two feet in diameter entered the Earth's atmosphere outside of Pittsburgh last night, according to NASA. The object, detected by three NASA meteor cameras, was moving at a speed of 45,000 miles per hour. Visibility was lost at an altitude of 13 miles, but the space agency...
