Scientists discover Earth-size planet that could sustain life

Technology
A newly discovered Earth-size planet that could sustain life is poised to become Earth's closest stellar neighbor in a cosmic "blink of the eye," scientists at the European Southern Observatory announced in a press release today. Ross 128 b is an exoplanet 11 light-years from our solar system, but it is moving closer and is predicted to become Earth's closest stellar neighbor in 79,000 years, scientists said. It is currently the second-closest temperate planet to Earth, after Proxima b. Every 9.9 days, Ross 128 b orbits a red dwarf star known as Ross 128. Ross 128 is relatively quiet and cool and has just over half the surface temperature of the sun, scientists said, which could make Ross 128 b conducive to life. The star Ross 128 is part of the constellation of Virgo. "Many red dwarf ...
Scientists design smart paper capable of detecting water, conducting electricity

Scientists design smart paper capable of detecting water, conducting electricity

Science
Nov. 7 (UPI) -- Scientists at the University of Washington have designed smart paper capable of sensing water and conducting electricity. The paper could be used to detect water leaks in city pipes.Even small leaks in a city's maze of pipes can prove costly. Left alone, the problem can get worse. And finding the leak can prove timely. The American Water Works Association estimate leaks cause 250,000 water line breaks every year, costing public water utilities an annual sum of $ 2.8 billion.Scientists hope their new smart paper can shrink those costs by making it easier to find and fix leaks.The paper can sense the presence of water and conduct an electric current to sound an alarm or trigger a light, alerting maintenance authorities to the presence of a leak."Water sensing is very challeng...
Scientists discover hidden chamber in Egypt's Great Pyramid

Scientists discover hidden chamber in Egypt's Great Pyramid

Technology
Scientists say they have found a hidden chamber in Egypt's Great Pyramid of Giza, in what would be the first such discovery in the structure since the 19th century and one likely to spark a new surge of interest in the pharaohs. In an article published in the journal Nature on Thursday, an international team said the 30-meter (yard) void deep within the pyramid is situated above the structure's Grand Gallery, and has a similar cross-section. The purpose of the space is unclear, and it's not yet known whether it was built with a function in mind or if it's merely a gap in the pyramid's architecture. Some experts say such empty spaces have been known for years. "This is a premier," said Mehdi Tayoubi, a co-founder of the ScanPyramids project and president of the Heritage Innovation Preserva...
Scientists map coastal communities most vulnerable to natural disasters

Scientists map coastal communities most vulnerable to natural disasters

Science
Nov. 2 (UPI) -- Scientists have identified coastal communities where poverty, poor infrastructure and exposure to the elements combine to create a unique level of vulnerability to natural disasters.These varying levels of risk are showcased on a new map of the Caribbean and South America published this week in the journal PLOS ONE."We found that more than 500,000 people in Latin America and the Caribbean are living in areas where coastal hazards and poverty converge," lead researcher Juliano Calil said in a news release. "These are communities where scarce critical resources are consistently placed in hazards-prone areas, further exacerbating the impacts of coastal hazards."The 2017 hurricane season decimated many vulnerable communities in the Caribbean. To better protect populations from ...
Mars Express' webcam helps ESA scientists study high-altitude clouds

Mars Express' webcam helps ESA scientists study high-altitude clouds

Science
Oct. 17 (UPI) -- A new survey of high-altitude clouds on Mars marks the first time researchers have used the webcam on the European Space Agency's Mars Express probe for scientific purposes.Until now, the webcam was mostly used for science outreach and education. But last year, ESA scientists upgraded the webcam with new software and began capturing images of the clouds and dust storms forming atop the Red Planet's edge -- the planet's "limb."The probe's other cameras are mostly designed to make high-resolution observations of small targets, but the webcam is ideal for wide-angle views of Mars' distant horizon."For this reason, limb observations in general are not so numerous, and this is why our images are so valuable in contributing to our understanding of atmospheric phenomena," Agustin...
