Solar Power Meets Half of Germany's Energy Demand
June 26, 2014 10:00 AM - Andrew Burger, Triple Pundit
A core facet of Chancellor Merkel's historic "Energiewende" clean energy transition, Germany has led the world in driving adoption of solar energy technology and systems. Although it is now pulling back hard on incentives, the market momentum created by its precedent-setting solar energy feed-in tariff (FiT) persists.
MIT study unearths neanderthal diet
June 26, 2014 09:03 AM - Editor, ENN
The popular conception of the Neanderthal as a club-wielding carnivore is, well, rather primitive, according to a new study conducted at MIT. Instead, our prehistoric cousin may have had a more varied diet that, while heavy on meat, also included plant tissues, such as tubers and nuts.
Soccer Under The Sun
June 20, 2014 08:00 AM - Winfield Winter, ENN
The 2014 FIFA World Cup Brazil is underway and off to a bright start. For the first time in the tournament's history, matches will be held in stadiums powered by solar energy. Footballers from the 32 nations represented may curse the sun and the swelter it brings, but Yingli Solar, the world's largest solar panel manufacturer and a FIFA World Cup Sponsor, has captured an opportunity on the world's biggest stage. Yingli Solar estimates its solar panels to generate more than 1MW per year and clean electricity for 25 years or more. The iconic Estádio do Maracanã that witnessed Pelé's 1000th career goal and much of Brazil's rich footballing history is one of the two sites that received this modern upgrade. This Rio de Janeiro landmark that opened in 1950 now boasts 1,500 Yingli Solar panels with the capability to produce 550MWh of clean electricity per year.
"Tuning" the silk: How spiders use vibrations to learn about their prey, mates, and web
June 18, 2014 01:36 PM - Allison Winter, ENN
The fine craftsmanship of a spider's web helps these eight-legged arachnids catch their prey. But these silk-threaded designs can tell a spider a lot more than what they will be having for dinner. The spider that sits in the middle of its web monitors the silk threads for vibrations. And according to a new discovery by researchers at the Universities of Oxford, Strathclyde, and Sheffield the frequencies of these vibrations carry specific information about the prey, mates, and even the structural integrity of the web.
Are we close to bringing back supersonic travel?
June 18, 2014 07:06 AM - Roger Greenway, ENN
Remember the Concorde? The supersonic passenger jet that flew from 1969 to almost 2000. It was not cost effective for the airlines, and extravagantly expensive for passengers. It was also cramped. The luxury was being able to fly from New York to London in about 3 hours! The Concorde had a big problem, the sonic boom it created when flying at supersonic speed. This led to governments restricting where it could fly supersonically and was a major factor in it not being economical to continue flying. That and a very advanced airframe that was getting old. The return of supersonic passenger travel may be coming closer to reality thanks to NASA’s efforts to define a new standard for low sonic booms. Several NASA aeronautics researchers will present their work in Atlanta this week at Aviation 2014, an annual event of the American Institute of Aeronautics and Astronautics. They will share with the global aviation community the progress they are making in overcoming some of the biggest hurdles to supersonic passenger travel.
Broccoli sprouts may help detox our bodies from air pollutants
June 16, 2014 06:43 PM - Editor, ENN
A clinical trial involving nearly 300 men and women residing in one of China's most polluted regions found that daily consumption of a half cup of broccoli sprout beverage produced rapid, significant and sustained higher levels of excretion of benzene, a known human carcinogen, and acrolein, a lung irritant.
Heinz and Ford to Team Up on Rolling Green Tomatoes
June 16, 2014 09:23 AM - RP Siegel, Triple Pundit
You could say that, at least until now, cars and tomatoes have basically nothing in common. Tomatoes go from green to red as they ripen, and cars, well, they seem to be getting greener. As part of this trend, Ford is one of several companies that have been pursuing a viable bio-based plastic that could substitute for the petroleum-based plastics that dominate the industry today. Indeed, as cars continue to reduce vehicle weight in order to improve fuel economy, the use of plastics is becoming ever more common.
Saving bees with spider venom?
June 11, 2014 08:32 AM - Steve Williams, Care2
With Europe and the United States slow to ban the pesticides that science says is probably drastically harming our bee populations, could one of the world's most venomous spiders hold one solution to saving our pollinators?
What does the temperature feel like on Mars?
June 11, 2014 05:32 AM - Sid Perkins, Science
Even though daytime temperatures in the tropics of Mars can be about —20°C, a summer afternoon there might feel about the same as an average winter day in southern England or Minneapolis. That’s because there’s virtually no wind chill on the Red Planet, according to a new study—the first to give an accurate sense of what it might feel like to spend a day walking about on our celestial neighbor. "I hadn't really thought about this before, but I'm not surprised," says Maurice Bluestein, a biomedical engineer and wind chill expert recently retired from Indiana University—Purdue University Indianapolis. The new findings, he says, "will be useful, as people planning to colonize Mars need to know what they’re getting themselves into."
Massive rocky planet challenges traditional views of planet formation
June 6, 2014 01:36 PM - NASA JPL
Astronomers have discovered a rocky planet that weighs 17 times as much as Earth and is more than twice as large in size. This discovery has planet formation theorists challenged to explain how such a world could have formed. "We were very surprised when we realized what we had found," said astronomer Xavier Dumusque of the Harvard-Smithsonian Center for Astrophysics, Cambridge, Massachusetts, who led the analysis using data originally collected by NASA's Kepler space telescope.
