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

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.
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

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.
Owl Monkeys are great Fathers! And they are loyal to their mates!
June 14, 2014 06:24 AM - Roger Greenway, ENN
Tomorrow is Father's day and animals are not normally thought of as being good fathers. For most species, the mothers do most of the work feeding and nurturing their young. Owl monkeys appear to be an exception! If there were a competition for "best father" in the animal kingdom, owl monkeys might very well win. Why? Because father owl monkeys provide most of the care needed by their young--carrying them almost all the time, even when chased by predators. By contrast, caregiving from owl monkey mothers to their young is limited almost exclusively to nursing. Considering the high prevalence of "deadbeat dads" and even "cannibal dads" in the animal kingdom, why--of all creatures--are father owl monkeys so attentive and protective of their young? This question is answered by Patricia C. Wright of Stony Brook University in the accompanying video.
Wasted heat from air conditioners causes warmer nighttime temperatures
June 12, 2014 08:01 AM - Allison Winter, ENN
With summer temperatures fast approaching, households across the country are installing and prepping air conditioning units in anticipation of hot, sticky weather. However, a potentially brutal cycle may be in store if summertime extreme-heat days are projected to become more frequent and intense as a result of climate change. According to a new study conducted in Phoenix by Arizona State University researchers, so much wasted heat is emitted by air conditioning units that it actually raises the city's outdoor temperature at night by 1-2.7 degrees! Consequently, these warmer temperatures may encourage individuals to further their demands and energy use of their air conditioners. The research, published last month in the Journal of Geophysical Research, investigates the effects of air-conditioning systems on air temperature and examines their electricity consumption for a semiarid urban environment.
FDA and EPA issue updated draft advice for fish consumption
June 10, 2014 10:32 AM - US EPA Newsroom
The U.S. Food and Drug Administration and the U.S. Environmental Protection Agency today issued updated draft advice on fish consumption. The two agencies have concluded pregnant and breastfeeding women, those who might become pregnant, and young children should eat more fish that is lower in mercury in order to gain important developmental and health benefits. The updated draft advice is consistent with recommendations in the 2010 Dietary Guidelines for Americans.
Hurricanes with female names result in greater death toll
June 3, 2014 07:49 AM - ClickGreen Staff, ClickGreen
Hurricanes with feminine names are likely to cause nearly three times as many deaths than storms with masculine names after new research found girl names are perceived as less threatening. A new University of Illinois study is warning to watch out for hurricanes with benign-sounding names like Dolly, Fay or Hanna because people in the path of these severe storms may take fewer protective measure, leaving them more vulnerable to harm.
Air Conditioning: Cooler on the Inside, Hotter on the Outside!
May 25, 2014 09:30 AM - Editor, ENN
We all love to be comfortable in our homes and businesses. We use air-conditioning to provide comfortable temperatures indoors. Air conditioners work basically by moving hotter air from inside to outside. Does this have an impact on climate? Global warming? A team of researchers from Arizona State University has found that releasing excess heat from air conditioners running during the night resulted in higher outside temperatures, worsening the urban heat island effect and increasing cooling demands. "We found that waste heat from air conditioning systems was maximum during the day but the mean effect was negligible near the surface. However, during the night, heat emitted from air conditioning systems increased the mean air temperature by more than 1 degree Celsius (almost 2 degrees Fahrenheit) for some urban locations," said Francisco Salamanca, a post-doctoral research scientist at Arizona State University's School of Mathematical and Statistical Sciences.
Climate change threatens US landmarks
May 22, 2014 09:10 AM - ClickGreen Staff, ClickGreen
The growing consequences of climate change are putting more than two dozen of the most iconic and historic sites in the US at risk, according to a new report. From Ellis Island to the Everglades, Cape Canaveral to California's César Chávez National Monument, a lengthy list of treasured sites is being threatened by the effects of climate change, including rising sea levels and fires.
