A mini-medical machine could mean a new power scheme for cardiac pacemakers. Rather than use batteries, engineering researchers at the University of Michigan say they can use vibrations from heartbeats themselves.
Their new device is designed to harvest energy from the reverberation of heartbeats through the chest and convert those to electricity to run a pacemaker or an implanted defibrillator. By taking the place of the batteries that power them today, the new energy harvester could save patients from repeated surgeries - the only way today to replace the batteries, which last five to 10 years.
A research team has announced discovery of molecular oxygen ions (O2+) in the upper atmosphere of Dione, one of the 62 known moons orbiting Saturn.
Forget mitigation and rationing, it is not the way cultures and progress work. The long-term solution is obviously to engage in basic research and come up with effective clean energy but also to create fewer emissions while development is in progress.
America never migrated to nuclear energy the way the French did so today up to 75 percent of electricity used in the United States is instead produced by coal-burning power plants and that means carbon dioxide (CO2) in the atmosphere and increased risk of global warming. To reduce the impact of current power generation, researchers are searching for porous materials to filter out the CO2 generated by those plants before it reaches the atmosphere, a process commonly known as carbon capture.
Scientists have reported the discovery of the floor of the world's oldest forest. They are now piecing together a view of this ancient site, dating back about 385 million years and - because virtually all studies have to reference global warming these days - they note their research could shed new light on the role of modern-day forests and their impact on climate change.
The recent discovery was made in the same area in Schoharie County, New York where fossils of the Earth's oldest trees, the Gilboa stumps, were discovered in the 1850s, 1920 and again in 2010 and were brought to the New York State Museum. The Museum has the world's largest and best collection of Gilboa fossil tree stumps.
What if bacteria could talk? Or use touch? A new study hypothesizes that bacterial cells may need to communicate in order to perform certain functions.
Astronomers have detected rapid changes in the brightness of embryonic stars within the well-known Orion Nebula, 1,350 light years from Earth, which appears prominently in the winter skies for European observers. Sometimes referred to as the Sword of Orion, the nebula lies below the three stars that form the belt of Orion the Hunter, one of the most easily recognized constellations.
It is one of the few nebulas visible to the naked eye and is a popular target for amateur astronomers.
