Still shellfish after 425 million years: Clam-like creature preserved perfectly in ancient fossil
...ncient shellfish not seen for 425 million years is recreated in vivid 3D images published today, following a unique fossil find in the UK. The 'articulate brachiopod' fossil, found in a quarry in Herefordshire, England, is the first of its kind to be preserved with its soft parts intact in 3D. It was discovere...University of Delaware researchers develop cancer 'nanobomb'
...e the microscopic bombs to kill cancer cells. They recreated the explosions in solutions including water, phosphate and salt, which meant the nanobombs could be used in the human body. In fact the explosions were more dramatic in saline solutions, Panchapakesan said. "The nanobomb is very selective, very loc...Modern technology helps shed light on illnesses in artists of the past
...s half a world away. Some also believe that Munch recreated the scene in 1893 while his sister, Laura, was being treated for schizophrenia. Was he trying to express his sister's emotional torment? It is also possible that he had a psychological illness and was projecting it into the painting. Modern patholog...Study provides new understanding of spontaneous hybridization
...uthward into central and southern Texas. They then recreated the original hybridization event by manually crossing two parent species. Not only were these hybrids resistant to the insects that attack sunflowers, they also produced more seeds than the uncrossed plants. "The results show for the first time that......one formation and degradation could potentially be recreated by drug treatments for osteoporosis, Crabtree said. Very little NFATc1 must be activated to build extra bone, Winslow noted, which means that it may be possible to up-regulate the calcineurin/NFATc pathway to promote bone formation without disturbing...Butterfly speciation event recreated

"We recreated the evolutionary steps that may have given rise to Heliconius heurippa, a hybrid butterfly species, in the lab," explains Jesus Mavarez, Molecular Evolution Fellow at the Smithsonian Tropical Research Institute. Sexual encounters between species resu......ical portions of Hoxa1 and Hoxb1, they effectively recreated a gene with the function that the original Hox1 performed more than 530 million years ago. The result: A mouse with a disabled Hoxb1 gene still was able to move eyelids, whiskers and ears because the reconstructed gene made up for the loss of Hoxb...ACS News Service Weekly PressPac -- April 18, 2007
...analyzing metals in the sediments, the researchers recreated a 1,000-year history of metal smelting in the area, predating Francisco Pizarro and his Spanish conquistadors by 600 years. Their findings show that smelters in the Morococha region of Peru switched from production of copper to silver around the time...Largest synthetic gene ever built offers insights into anti-malarial drug resistance
... the researchers say that with the addition of the recreated gene, PfMDR1 and its protein, they have all the biomolecular tools necessary to molecularly understand how the malarial parasite Plasmodium falciparum (P. falciparum), has become resistant to most of the drugs that could once destroy it. They have al...
