Your color printer is an astonishing feat of precision engineering. It mixes four colors carefully enough to achieve more than a million different hues and shades. Then, each color is placed on the paper, with better than pinpoint accuracy. Now, a group of chemists is exploiting that precision engineering to screen millions of different chemical reactions.
Researchers have found a new way, using ultrathin aluminum oxide, to control the properties of...
The emerging field of molecular electronics could take our definition of portable technology to...
Taking a cue from an American TV program, the Chinese city of Chongqing has created a smartphone sidewalk lane, offering a path for those too engrossed in messaging and tweeting to watch where they're going.
Things can go downhill fast when a patient has sepsis, a life-threatening condition in which bacteria or fungi multiply in a patient's blood— often too fast for antibiotics to help. A new device inspired by the human spleen may radically transform the way doctors treat sepsis.
Researchers have devised a new simulation technique that reliably predicts the structure and behavior of different materials, in order to accelerate the development of next-generation batteries for a wide range of applications.
Parts of the flag that inspired America’s national anthem were snipped off and handed out as mementos. The Smithsonian has been reacquiring some of those fragments and adding to their collection, verifying them through high-tech methods.
In a statement this week, Yahoo said that, in 2007, the government amended a law to demand user information from online services, prompting a challenge during the George W. Bush administration. The government called for the huge fine in 2008 if Yahoo didn't go along with an expansion of U.S. surveillance by surrendering online information, a step the company regarded as unconstitutional.
Two engineering students were so chilled by the polar vortex last winter that they decided to take matters into their own hands by inventing the world's first intelligent, heated base layer. In just six months, the pair founded a company, FuelWear, and created a feather-light, washable and snuggly undershirt they call the Flame Base Layer.
Researchers have shown the use of sound to communicate with an artificial atom. They can thereby demonstrate phenomena from quantum physics with sound taking on the role of light.
From Apple's new smartwatch that tracks heartbeats to contact lenses that measure blood sugar— Silicon Valley is pouring billions into gadgets and apps designed to transform health care. But the tech giants that have famously disrupted so many industries are now facing their own unexpected disruption: regulation.
Critics say Nevada lawmakers are gambling with taxpayers' money, but they clearly were in the minority as legislators moved forward with an unprecedented package of up to $1.3 billion in incentives they hope to approve in the days ahead to bring Tesla Motors' $5 billion battery factory to the state.
A team of researchers has discovered a way to cool electrons to -228 C without external means and at room temperature, an advancement that could enable electronic devices to function with very little energy. The process involves passing electrons through a quantum well to cool them and keep them from heating.
More than half of American adults own a smartphone and almost a third of them “can’t imagine living” without the device. The rapidly evolving landscape of applications has changed the way we socialize, conduct bank transactions, find our way to a friend’s house and track diet and exercise.
Researchers, using a brain-computer interface, have shown why learning something similar to what you already know makes learning new things easier. Learning unfamiliar ideas or behavior is more difficult. While that sounds self-evident, the researchers have actually watched it happen in animal brains to learn how it works.
For detecting cancer, manual breast exams seem low-tech compared to other methods such as MRI. But scientists are now developing an "electronic skin" that "feels" and images small lumps that fingers can miss. Knowing the size and shape of a lump could allow for earlier identification of breast cancer, which could save lives.
There is more to Stonehenge than meets a visitor's eye. Researchers have produced digital maps of what's beneath the World Heritage Site, using ground-penetrating radar, high-resolution magnetometers and other techniques to peer deep into the soil beneath the famous stone circle.
A smart headlight enables drivers to take full advantage of their high beams without fear of blinding oncoming drivers or suffering from the glare that can occur when driving in snow or rain at night. The programmable headlight senses and tracks virtually any number of oncoming drivers, blacking out only the small parts of the headlight beam that would otherwise shine into their eyes.
Wireless researchers have found a way to make the most of the unused UHF TV spectrum by serving up fat streams of data over wireless hotspots that could stretch for miles.
A new map identifies areas where animals are likely to be infected with the Ebola virus as a first step toward understanding where future outbreaks of the disease may occur. The map, based on a model created by scientists, predicts that in animal populations the Ebola virus is likely to be circulating across a vast swathe of forested Central and West Africa.
Scientists have married two unconventional forms of carbon– one shaped like a soccer ball, the other a tiny diamond– to make a molecule that conducts electricity in only one direction. This tiny electronic component, known as a rectifier, could play a key role in shrinking chip components down to the size of molecules to enable faster, more powerful devices.
One of the most famous portraits of George Washington will soon get a high-tech examination and face-lift of sorts with its first major conservation treatment in decades. The Smithsonian's National Portrait Gallery has begun planning the conservation and digital analysis of the full-length "Lansdowne" portrait of the first president that was painted by Gilbert Stuart in 1796.
Unless one is attending an aeronautics convention or going on a trip, noise associated with aircraft engines is rarely tolerable. Now, different means of significantly reducing that noise are being tested in the lab.
New research could lead to a generation of light detectors that can see below the surface of bodies, walls and other objects. Using the special properties of graphene, a prototype detector is able to see an extraordinarily broad band of wavelengths.
In 2011, the Community Seismic Network began taking data from small, inexpensive accelerometers in the greater Pasadena area. Able to measure both weak and strong ground movement along three axes, these accelerometers promise to provide very high-resolution data of shaking produced by seismic activity in the region.
One of the most important molecules on earth, calcium carbonate, crystallizes into chalk, shells and minerals the world over. Researchers have used a powerful microscope that allowed them to see the birth of crystals in real time, giving them a peek at how different calcium carbonate crystals form.
The sea ice cap that covers the Arctic Ocean has been changing dramatically. Its ice is thinner and more vulnerable– at summer minimum it now covers more than 1 million fewer square miles than in the late 1970s. A key part of the story of how the world was able to witness and document this change centers on meticulous work over decades by a small group of scientists at NASA.
Scientists’ underwater cameras got a boost this summer as researchers captured the world’s first real-time images and simultaneous chemical analysis of nanostructures while “underwater,” or in solution.
