A newly discovered solar system— with five small rocky planets— makes ours look like a baby. Astronomers announced today that this solar system is 11.2 billion years old. By comparison, our solar system is 4.5 billion years old.
A Kevlar membrane can enable more durable batteries that adapt to various environments. The...

NASA expects to save millions of dollars sending astronauts to the International Space Station, once its commercial crew program starts flying in a couple of years. SpaceX and Boeing say they are on track to carry out their first manned test flights to the space station in 2017.
The trachea is a tube that connects the upper respiratory tract to the lungs and helps carry air to the lungs. Traditional treatments for tracheal diseases usually involve removal of the affected tracheal segment. However, 3-D printing can effectively create a biodegradable tracheal segment containing a patient’s own cells for use in complex tracheal reconstruction.
Doctor after doctor said removing the tumor causing Pamela Scott's unrelenting headaches would require cutting open the top of her skull and pushing aside her brain. Then one offered a startling shortcut— operating through her eyelid. The idea: make a small incision right in the crease and sneak past the eyeball into the hard-to-reach center of the head.
Private information would be much more secure if individuals moved away from cloud-based storage toward peer-to-peer systems, where data is stored in a variety of ways and across a variety of sites. By parceling and spreading data across multiple sites, and weaving it together like a tapestry, not only would our information be safer, it would be quicker to access and could potentially be stored at a lower overall cost.
Drone technology, already used in other countries, can make farmers more efficient by helping them locate problem spots in vast fields or ranchlands. Increased efficiency could mean lower costs for consumers and less impact on the environment if farmers used fewer chemicals because drones showed them exactly where to spray.
It’s great that it’s so easy to keep in contact with close friends and family, almost anywhere in the world. Yet, at a time when we are battling to keep carbon emissions under control, can we really justify the energy consumption involved in streaming cat videos in ever-higher definition?
A device, possibly an unmanned aerial drone, was found on the White House grounds during the middle of the night while President Barack Obama and the first lady were in India, but his spokesman said Monday that it posed no threat.
Fuel prices may be at historic lows at the moment but when they rise again, what is the best strategy to save money at the pump? One theory on how to conserve fuel is to put less of it in your tank. The thinking is that you carry around less weight in the car, which means the engine does not have to work as much, which means saving on fuel.
A revolutionary device has been shown to significantly lower blood pressure among patients with uncontrolled high blood pressure, compared to those treated with usual drug measures. The device is a paper clip-sized implant that is inserted between the artery and vein in the upper thigh, in a procedure lasting around 40 minutes under local anesthetic.
The process of converting the sun’s energy into liquid fuels requires a sophisticated, interrelated series of choices. Now, scientists have outlined a tool to help engineers better gauge the overall yield, efficiency and costs associated with scaling solar-fuel production processes up into large-scale refineries.
A Wyoming company says it will replace a pipeline that broke and spilled oil into the Yellowstone River with a new line buried more deeply to protect against future accidents. The spill contaminated the water supply for 6,000 residents of Glendive, Montana.
New laser-driven compression experiments reproduce the conditions deep inside exotic super-Earths and giant planet cores, and the conditions during the violent birth of Earth-like planets, documenting the material properties that determined planets' formation and evolution processes.
On Nov. 12, 2014, the Rosetta mission made history when its Philae lander touched down on the surface of comet 67P/Churyumov-Gerasimenko. While this exciting technical achievement gained lots of headlines, it was only the beginning for researchers back on Earth who are receiving and analyzing comet data. The latest chapter in the story provides the closest and most detailed look at a comet that scientists have ever seen.
Scientists have used lasers to transform metals into extremely water repellent, or super-hydrophobic, materials without the need for temporary coatings. Super-hydrophobic materials are desirable for a number of applications such as rust prevention, anti-icing or even in sanitation uses. However, most current hydrophobic materials rely on chemical coatings.
A developer has knocked over the Westinghouse atom smasher east of Pittsburgh but plans to preserve the structure no matter what happens to the property it was on. The brick building at the base of the five-story, light bulb-shaped atom smasher was in too much disrepair to save.
A handwritten notebook by Alan Turing, the World War II code-breaking genius, is going on the auction block. The 56-page manuscript was written at the time the British mathematician and computer science pioneer was working to break the seemingly unbreakable Enigma codes used by the Germans throughout World War II. It is expected to bring at least $1 million.
In a novel twist in cybersecurity, scientists have developed a self-cleaning, self-powered smart keyboard that can identify computer users by the way they type. The device could help prevent unauthorized users from gaining direct access to computers.
It may not come as a surprise that the more time college students, particularly freshmen, spend on Facebook, the more their grades suffer. In a study, an associate professor found that, while freshman struggle to balance their use, social media is less of a problem for upper classmen. The difference relates to self-regulation.
Born in Windsor, Connecticut, on Jan. 21, 1743, John Fitch was a clockmaker, engineer and inventor who is known for introducing steamboats to the U.S. In 1785, he designed the first American steamboat. Unable to secure the money for his venture, he instead persuaded states to give him a 14-year monopoly on steamboat traffic.
When a person lives on less than $2 a day— as some 2.7 billion people around the world do— there isn’t room for a product like a solar lantern or a water filter to fail. With so many products on the market, how do you choose the right one? Now, researchers have released a report that could help answer that question through a new framework for technology evaluation.
By producing complex multimodal fibers that could be less than the width of a hair, researchers have created a system that could deliver optical signals and drugs directly into the brain, along with simultaneous electrical readout to continuously monitor the effects of the various inputs.
In Silicon Valley, it's never too early to become an entrepreneur. Just ask 13-year-old Shubham Banerjee. The California eighth-grader has launched a company to develop low-cost machines to print Braille, the tactile writing system for the visually impaired. Tech giant Intel Corp. recently invested in his startup.
The team behind a solar-powered aircraft that is attempting to fly around the world says the clean-energy plane will stop in India, China and the U.S. in a historic journey. The lightweight Solar Impulse 2, a larger version of a single-seat prototype that first flew five years ago, is aiming to become the first plane ever to circumnavigate the globe using only the power of the sun to drive its four propellers.
Scientists have succeeded in reading parts of an ancient scroll that was buried in a volcanic eruption almost 2,000 years ago, holding out the promise that the world's oldest surviving library may one day reveal all of its secrets. The scroll is among hundreds retrieved from the remains of a lavish villa at Herculaneum that, along with Pompeii, was one of several Roman towns that were destroyed when Mt. Vesuvius erupted in A.D. 79.
The scientist behind a new talking robot in Japan says people should stop expecting robots to understand them, and instead try to chime in with robotic conversations. The 11-inch tall button-eyed Sota, which stands for "social talker," is programmed to mainly talk with a fellow robot, and won't be trying too hard to understand human speech— the major, and often frustrating, drawback of companion robots.
