| King David's palace uncovered in Judean Shephelah Posted: 21 Jul 2013 06:50 PM PDT King David's Palace has just been uncovered in the Judean Shephelah. Royal storerooms were also revealed in the archaeological excavation. These are the two largest buildings known to have existed in the tenth century BCE in the Kingdom of Judah.  |
| Current efforts will not save the world's most endangered cat Posted: 21 Jul 2013 01:17 PM PDT Almost 100 million euros has been spent so far on conservation efforts for the last 250 remaining Iberian lynxes in the wild. But the charismatic species is likely to go extinct within 50 years because the current management plans do not account for the effects of climate change. If they did, the population might increase instead concludes a new international study. The study highlights the importance of integrating climate models in management plans for biodiversity.  |
| Common stem cell in heart and lung development explains adaption for life on land Posted: 21 Jul 2013 01:17 PM PDT Biologists have known that the co-development of the cardiovascular and pulmonary systems is a recent evolutionary adaption to life outside of water. Researchers show that the pulmonary vasculature develops even in the absence of the lung. Mice in which lung development is inhibited still have pulmonary blood vessels, which revealed to the researchers that cardiac progenitors, or stem cells, are essential for cardiopulmonary co-development.  |
| Ancient ice melt unearthed in Antarctic mud: 20 meter sea level rise, five million years ago Posted: 21 Jul 2013 01:15 PM PDT Global warming five million years ago may have caused parts of Antarctica's large ice sheets to melt and sea levels to rise by approximately 20 meters, scientists report.  |
| Flip of mitotic spindle has disastrous consequences for epithelial cells Posted: 21 Jul 2013 01:14 PM PDT Investigators have used genetics and live cell imaging to illuminate molecular mechanisms that position the cell division machinery in growing tissues.  |
| Sex chromosome shocker: The 'female' X a key contributor to sperm production Posted: 21 Jul 2013 01:13 PM PDT Painstaking new analysis of the genetic sequence of the X chromosome -— long perceived as the "female" counterpart to the male-associated Y chromosome -— reveals that large portions of the X have evolved to play a specialized role in sperm production.  |
| World's first water treatment techniques using apple and tomato peels Posted: 18 Jul 2013 07:10 AM PDT Scientists experimented with water treatment techniques using materials that are easily available, and came up with novel ways to purify water using the peels of apples and tomatoes.  |
