For the first time, astronomers have caught a so-called dwarf galaxy in the process of swallowing another, even smaller galaxy. Whether such mergers are important in the formation of the tiniest galaxies has been the subject of debate among theoreticians. Now, thanks to research by two independent g...
For the ninth time, the laser community will be coming together at the International Laser Technology Congress AKL'12 from May 9-11, 2012. Catering to the interests of laser manufacturers, users and potential users, AKL'12 will be offering practical examples of innovative industry applications toget...
Cyclone Jasmine continues to wind between New Caledonia and Vanuatu and bring cyclone-force winds, heavy rain and very rough surf. NASA's Aqua satellite passed overhead early on February 7 and noticed the strongest part of the cyclone was around the center and north and east of the center. Aqua data...
A monsoon trough continues to drench northeastern Australia and NASA's Tropical Rainfall Measuring Mission (TRMM) satellite measured and calculated the rainfall in the region.
A green thumb is required where plants are to grow abundantly - that also applies to watering them in dry areas. If they are watered too much, then the soil becomes saline; if the plants receive too little moisture, they let their leaves droop and, in the worst case, they wither.
Climate change has impacts on forests, fields, rivers - and thereby on humans that breathe, eat and drink. To assess these impacts more accurately, a comprehensive comparison of computer-based simulations from all over the world will start this week. For the first time, sectors ranging from ecosyste...
An endocrine hormone used in clinical trials as an anti-obesity and anti-diabetes drug causes significant and rapid bone loss in mice, raising concerns about its safe use, UT Southwestern Medical Center researchers have shown.
The Max Planck Institute for Evolutionary Anthropology, in Leipzig, Germany, has completed the genome sequence of a Denisovan, a representative of an Asian group of extinct humans related to Neandertals.
While epilepsy surgery is a safe and effective intervention for seizure control, medical therapy remains the more prominent treatment option for those with epilepsy. However, a new 26-year study reveals that following epilepsy surgery, nearly half of participants were free of disabling seizures and ...
New evidence-based guidelines from the American College of Chest Physicians (ACCP) recommend considering individual patients' risk of thrombosis when deciding for or against the use of preventive therapies for deep vein thrombosis (DVT) and venous thromboembolism (VTE).
In a study of the harsh but beautiful White Sands National Monument in New Mexico, University of Pennsylvania researchers have uncovered a unifying mechanism to explain dune patterns. The new work represents a contribution to basic science, but the findings may also hold implications for identifying...
Tropical Storm 11P has formed in the South Pacific Ocean, and NASA's Aqua satellite captured an infrared image of its cloud temperatures, revealing power in the cyclone.
