Spinach gave Popeye super strength, but it also holds the promise of a different power for a group of scientists: the ability to convert sunlight into a clean, efficient alternative fuel. Physicists are using spinach to study the proteins involved in photosynthesis, the process by which plants convert the sun's energy into carbohydrates used to power cellular processes. Artificial photosynthesis could allow for the conversion of solar energy into renewable, environmentally friendly hydrogen-based fuels.
The discovery of a new material combination that could lead to a more efficient approach to computer memory and logic is the first promising indication that it may be possible to build a practical technology with a novel material known as a 'topological insulator.' The research team's results show that such a scheme can be 10 times more efficient for controlling magnetic memory or logic than any other combination of materials measured to date.
A groundbreaking nanotechnology-inspired sensor picks up the scent of explosives molecules better than a detection dog's nose. The device is mobile, inexpensive, and highly accurate, detecting explosives in the air at concentrations as low as a few molecules per 1,000 trillion. Existing explosives sensors are expensive, bulky and require expert interpretation of the findings.
A crystal wedding in the nanocosmos may lead to fast multi-functional processing units on single chip
Researchers have succeeded in embedding nearly perfect semiconductor crystals into a silicon nanowire. With this new method of producing hybrid nanowires, very fast and multi-functional processing units can be accommodated on a single chip in the future.
Researchers have developed a device that allows multiple robotic platforms to follow the path of certain odors. A technology which could aid the search and rescue of people in case of natural disasters such as earthquakes, hurricanes or floods.
Interest in magnetic random access memory (MRAM) is escalating, thanks to demand for fast, low-cost, nonvolatile, low-consumption, secure memory devices. MRAM boasts all of these advantages as an emerging technology, but so far it hasn't been able to match flash memory in terms of storage density. A research team reports an intriguing new multi-bit MRAM storage paradigm with the potential to rival flash memory.
Scientists use simple, low cost laser technique to improve properties and functions of nanomaterials
By ‘drawing’ micropatterns on nanomaterials using a focused laser beam, scientists could modify properties of nanomaterials for effective applications in photonic and optoelectric applications.
For the first time, researchers have used a cutting-edge microscope to study the relationship between the atomic geometry of a ribbon of graphene and its electrical properties.
The yield so far is small, but chemists have developed a low-energy, solution-based mineral substitution process to make a precursor to transparent thin films that could find use in electronics and alternative energy devices.
Inspired by science fiction, three bowling ball-size free-flying Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) have been flying inside the International Space Station since 2006. These satellites provide a test bed for development and research, each having its own power, propulsion, computer, navigation equipment, and physical and electrical connections for hardware and sensors for various experiments.
Scientists have uncovered the secret to twisting light at will. It is the latest step in the development of photonics, the faster, more compact and less carbon-hungry successor to electronics. A random find in the washing basket led the team to create the latest in a new breed of materials known as metamaterials. These artificial materials show extraordinary properties quite unlike natural materials.
By examining a patient’s family medical history, physicians try to determine if there is an increased risk of the patient developing a particular disease or inherited condition. From a spiritual perspective, however, Christians are part of the family of God, their father God, his Son Jesus, and The Holy Spirit; and there is neither sickness nor disease in the history of this family, and there never will be. When Jesus died on the cross, He took upon Himself as a vaccination, all sickness and disease known and unknown to man and provided us with immunity from them. We as Christians are not, therefore, at risk for any sickness or disease.
