The ancient Mongols have a reputation for having been fierce warriors. A new study shows them to have been unmatched polluters. Ancient copper and silver production created four times more pollution than today’s methods.
Martian colonists could use an innovative new technique to harvest energy from carbon dioxide....
A toilet, conveniently situated near the Student Union Bar at a university, is proving pee can...
A new paint that makes robust self-cleaning surfaces has been developed. The coating can be applied to clothes, paper, glass and steel and when combined with adhesives, maintains its self-cleaning properties after being wiped, scratched with a knife and scuffed with sandpaper.
Wearable electronics are gaining traction among consumers, but these gadgets' versatility is still held back by the stiff, short-lived batteries that are required. The limitations, however, could soon be overcome. Scientists are reporting the first durable, flexible cloth that harnesses human motion to generate energy.
By showing a robot how to write letters, children improve their writing skills and gain self-confidence. When a robot struggles to write on a tablet a little girl kindly steps in to help, writing out the word to show the robot how to do it. She puts in effort to teach the robot... without realizing that in reality she is the one who is improving her writing skills.
Caesar Augustus, the founder of the Roman Empire once famously boasted, “I found Rome a city of bricks and left it a city of marble.” Was he telling the truth or making an empty claim? A researcher decided to uncover the truth behind Augustus’ famous declaration by using advanced modeling software to reconstruct the city of seven hills in its entirety and observing how it changed during the period when he was in power.
Researchers have created a new thermoelectric material, intended to generate electric power from waste heat– from a vehicle tailpipe, for example, or an industrial smokestack– with greater efficiency and higher output power than currently available materials.
Scientists have mapped changes in communication between nerve cells as rats learned to make specific decisions in response to particular sounds. The researchers then used this map to accurately predict the rats’ reactions. These results add to our understanding of how the brain processes sensations and forms memories to inform behavior.
The rise of electronic currency will lead to the phasing out of physical cash in Australia within a decade, according to an expert. He believes cash may be a thing of the past.
Digital health investments are booming, according to Rock Health, a venture capital (VC) firm that monitors investments in this sector. Shortcomings in the fast-evolving digital health care arena are becoming obvious, so Harvard Univ. is challenging those notions with technology.
Some of the world's largest airlines are banning bulk shipments of rechargeable batteries in the face of mounting evidence of their potential to cause catastrophic in-flight fires. Citing safety concerns, United Airlines has become the second major U.S. airline to announce it will no longer accept bulk shipments of lithium-ion batteries, which are used to power everything from smartphones to laptops to power tools.
Small semi-aqueous arthropods, such as mosquitoes and water striders, are free to go about their waterborne business. By examining the forces that the segments of mosquito legs generate against a water surface, researchers have unraveled the mechanical logic that allows the mosquitoes to walk on water, which may help in the design of biomimetic structures, such as aquatic robots and small boats.
Light behaves both as a particle and as a wave. Since the days of Einstein, scientists have been trying to directly observe both of these aspects of light at the same time. Now, scientists have succeeded in capturing the first-ever snapshot of this dual behavior.
Alexander Graham Bell, the man credited with inventing the telephone, was born in Scotland on March 3, 1847, without a middle name. It’s no surprise he was interested in sound and communication as his father, brother and grandfather all worked in elocution and his mother and wife were both deaf.
Australia, Indonesia and Malaysia will lead a trial of an enhanced method of tracking aircraft over remote oceans to allow planes to be more easily found should they vanish, like Malaysia Airlines Flight 370. The announcement comes one week ahead of the anniversary of the disappearance of Flight 370, which vanished last year with 239 people on board. No trace of the plane has been found.
For its next technological trick, Google will show you what it's like to zip through trees in the Amazon jungle. The images released today are the latest addition to the diverse collection of photos supplementing Google's widely used digital maps.
Researchers and engineers collaborated to print catheters, stents and filaments that were bioactive, giving these devices the ability to deliver antibiotics and chemotherapeutic medications to a targeted area in cell cultures.
There is a resolution revolution underway. Building powerful instruments that shatter the physical limits of optical microscopy, scientists are beginning to watch molecular processes as they happen, and in three dimensions.
How can a humpback whale and a device that works on the same principle as the clicker that starts your gas grill help an unmanned aerial vehicle fly longer and with more stability? Well, it all starts with biological structures called tubercles that the whale uses for its unique maneuvers in the ocean.
With half a second's planning, an animal’s brain prepares it to quickly and precisely execute complex movements. Scientists have identified a neural circuit that transforms the flurry of activity that occurs during this preparatory period into commands that direct muscle movements.
For nearly half a century, scientists have been trying to replace precious metal catalysts in fuel cells. Now, for the first time, researchers have shown that an inexpensive metal-free catalyst performs as well as costly metal catalysts at speeding the oxygen reduction reaction in an acidic fuel cell.
Raw milk is milk that has not undergone pasteurization, the bacteria-killing heat treatment designed to reduce human pathogens and increase shelf life. Unpasteurized milk can contain potentially harmful and deadly pathogens. So, why do people go so crazy for raw milk? They do so because of the supposed health benefits, which include improved immunity, allergy relief and gastrointestinal health.
Computers, cellphones and landlines in Arizona were knocked out of service for hours, ATMs stopped working, 911 systems were disrupted and businesses were unable to process credit card transactions— all because vandals sliced through a fiber-optic Internet cable buried under the rocky desert. This raises questions about the vulnerability of the nation's Internet infrastructure.
Internet service providers like Comcast, Verizon, AT&T, Sprint and T-Mobile now must act in the "public interest" when providing a mobile connection to your home or phone, under rules approved today by a divided FCC. The plan, which puts the Internet in the same regulatory camp as the telephone, represents the biggest regulatory shakeup to the industry in almost two decades.
A spacewalking astronaut ended up with unwanted water in his helmet after breezing through a cable and lube job outside the International Space Station. The leak was scarily reminiscent of a near-drowning outside the orbiting complex nearly two years ago.
Many car buyers weighing whether they should go all electric to help the planet have at least one new factor to consider before making the switch: geography. Based on a study of a commercially available electric car, scientists are reporting that emissions and driving range can vary greatly depending on regional energy sources and climate.
Computers already have bested human champions in "Jeopardy!" and chess, but artificial intelligence now has gone to master an entirely new level: "Space Invaders." Google scientists have cooked up software that can do better than humans on dozens of Atari video games from the 1980s but not "Ms. Pac Man."
