Astronomers have used a worldwide network of radio telescopes to resolve a controversy over the distance to a famous star cluster— a controversy that posed a potential challenge to scientists' basic understanding of how stars form and evolve. The new work shows that the measurement made by a cosmic-mapping research satellite was wrong.
Thanks to the dreams of a student, we now know more about where and how imagination happens in...
Holograms made of tiny particles of silver could double the amount of information that can be...
The famous fictional detective Sherlock Holmes used a magnifying lens to reveal barely visible but important evidence. Astronomers are now combining the power of many telescopes on Earth and in space with a vastly larger form of cosmic lens to study a case of vigorous star formation in the early Universe.
Researchers have created a CMOS-compatible, biomimetic color photodetector that directly responds to red, green and blue light in much the same way the human eye does.
Modern cryptography is not infallible. All encryption types, among which we can find the widely used RSA, can theoretically be broken. If so, how do we ensure that our data remains protected? The answer lies on the time and computational effort required to break the code.
European space officials say they're investigating whether the inaccurate deployment of two satellites will complicate their efforts to develop a new Galileo satellite navigation system that would rival America's GPS network.
A quantum effect in which excited atoms team up to emit an enhanced pulse of light can be turned on its head to create super-absorbing systems to make the ultimate camera.
About 63 trillion gallons of water have been lost to drought in the western U.S., enough to blanket the region with four inches of water, according to a study. Researchers arrived at the conclusion by measuring the level of the earth's crust with a network of GPS stations that is normally used to predict earthquakes.
A team of researchers has developed an innovative method for using affordable, consumer-grade 3-D printers and materials to fabricate custom medical implants that can contain antibacterial and chemotherapeutic compounds for targeted drug delivery.
A team has developed an algorithm that enables a drone to monitor aspects of its “health” in real time. With the algorithm, a drone can predict its fuel level and the condition of its propellers, cameras and other sensors throughout a flight, and take proactive measures— for example, rerouting to a charging station— if needed.
The National Park Service has banned drones from flying over the Appalachian Trail. The Park Service said the interim rule prohibits launching, landing or operating unmanned aircraft from or on Appalachian National Scenic Trail lands.
Researchers have developed a way to use a laser to measure people's blood sugar, and, with more work to shrink the laser system to a portable size, the technique could allow diabetics to check their condition without pricking themselves to draw blood.
Researchers have developed methods for electronically manipulating the flight muscles of moths and for monitoring the electrical signals moths use to control those muscles. The work opens the door to the development of remotely controlled moths, or “biobots,” for use in emergency response.
The Factories of the Future multi-annual roadmap for the years 2014-2020 under Horizon 2020, the European Union (EU) Framework Program for Research and Innovation, sets a vision that echoes similar projects worldwide.
It’s often said that humans are wired to connect: the neural wiring that helps us read the emotions and actions of other people may be a foundation for human empathy. But for the past eight years, research has been using neuroscience technologies that gauge subconscious emotions by monitoring brain and body activity to show just how powerfully we also connect to media and marketing communications.
Although body motion sensors already exist in different forms, they have not been widely used because of their complexity and cost of production. Now, researchers have treated common elastic bands with graphene to create a flexible sensor that is sensitive enough for medical use and can be made cheaply.
The Obama administration has concluded it will not publicly disclose federal records that could shed light on the security of the government's health care website because doing so could potentially allow hackers to break in.
By zapping the air with a pair of powerful laser bursts, researchers have created highly focused pathways that can channel electricity through the atmosphere. The technique can potentially direct an electrical discharge up to 33 feet away or more, shattering previous distance records for transmitting electricity through air.
Spacewalking astronauts launched a tiny Peruvian research satellite Monday, setting it loose on a mission to observe Earth. Russian Oleg Artemiev cast the four-inch box off with his gloved right hand from the ISS. The nanosatellite gently tumbled as it cleared the vicinity of the orbiting complex, precisely as planned.
The Obama administration has said it is taking a first step toward requiring that future cars and light trucks be equipped with technology that enables them to warn each other of potential danger in time to avoid collisions.
Laser physicists have found a way to make atomic force microscope probes 20 times more sensitive and capable of detecting forces as small as the weight of an individual virus.
Your next commuter car could have two seats, three wheels and get 84 miles to the gallon. Elio Motors wants to revolutionize U.S. roads with its tiny car, which is the same length as a Honda Fit but half the weight. With a starting price of $6,800, it's also less than half the cost.
Scientists have released a data-visualization tool that lets users highlight aberrations and possible patterns in a graphical display. The tool then automatically determines which data sources are responsible for which results.
Through commands, autonomous devices arranged selves into vast, complex shapes in the first 1,000-robot flash mob.
Genomic prediction, a new field of quantitative genetics, is a statistical approach to predicting the value of an economically important trait in a plant, such as yield or disease resistance. Now, a research team has used the method to predict the performance of hybrid rice— the yield, growth-rate and disease resistance. The new technology could potentially revolutionize hybrid breeding in agriculture.
Scientists have developed a single-use contact lens capable of measuring intraocular pressure continuously for 24 hours. This could track glaucoma day and night— a minor revolution for specialists.
