X-Ray Beams And Fruit Fly 'Flight Simulator' Aid Scientists' View Of Muscle Power

...uding human cardiac muscle, mean that the research may be adaptable for other uses. “Both insect flight and human heart muscles store energy during each beat that is later used to help flap the wings or expand the heart after contraction. We found that flying insects store much of the elastic energy in ...

Unexpressed But Indispensable -- The DNA Sequences That Control Development

...development. This clustering of CNEs suggests they may not only attract transcription factors, but may also influence the local topology of the DNA, thereby controlling access to their associated gene. S...

...damental clues as how cells move." These findings may also open the door to using PI3-kinase inhibitors or other agents that lower PIP2 and PIP3 levels to slow the spread of Listeria and control infection in patients who are not responding to antibiotics, although that application is a long way off, say...

UF Researchers Map Bacterial Proteins That Cause Tooth Loss

...ther oral pathogens to determine what interactions may exist that contribute to infection, he said. “This study is important in that we now have an understanding of the protein expression on a global scale for this pathogen,?Lamont said. “Now we need to see how it adapts to various situations present in...

Photos show jaguar vamping for camera

...using the remote cameras to census the park, which may contain more jaguars than any protected area in Latin America. Normally the cameras, which are tripped by an infrared beam, capture little more than a fleeting glimpse of wildlife. No one knows why this particular jaguar spent so much time in front ...

The death of large trees ?trees that may take centuries to reach the top of the forest canopy and have trunks greater than 10 inches in diameter -- increased from about one percent per year before the rainfall exclusion began to nine percent in the fourth year of the experiment, when soil w...

Implanted Devices Detect High-Risk Heart Failure Patients

...tion and mortality one year later. "This approach may play a significant role in targeting a subset of heart failure patients for whom we need to be more aggressive if we don't see early improvement in heart rate variability," Gilliam said. "We would expect that as their heart function improves after im...
