Flying Thunder
June 17, 2013 05:05 PM - Andy Soos, ENN
Jets are quite loud especially if they fly over your home much less for those closer like passengers or those at an airport. When jet-powered passenger aircraft first went into service in the 1950s, their engines were as loud as rock bands. Times have changed, but public dismay over jet noise has not. EurActiv reports from the Paris Air Show. Today’s engines are on average 75% quieter than those produced at the dawn of the jet age. This is the result, manufacturers say, of steady technological improvements that along with more aerodynamic aircraft have reduced the nuisance of flying for passengers and those on the ground.
Energy saving measures boost house prices, new research reveals
June 17, 2013 08:49 AM - Editor, ClickGreen
Energy saving improvements made to a property could increase its value by 14 per cent on average - and up to 38 per cent in some parts of England - new research has shown. For an average home in the country, improving its EPC (Energy Performance Certificate) from band G to E, or from band D to B, could mean adding more than £16,000 ($25,000 USD) to the sale price of the property.
Memory Loss and Gain
June 17, 2013 08:35 AM - Andy Soos, ENN
Would it not be nice to take a pill and regain that elusive memory? We are all forgetful at times and without a clue as to how to get it better. Memory improved in mice injected with a small, drug-like molecule discovered by UCSF San Francisco researchers studying how cells respond to biological stress. The same biochemical pathway the molecule acts on might one day be targeted in humans to improve memory, according to the senior author of the study, Peter Walter, PhD, UCSF professor of biochemistry and biophysics and a Howard Hughes Investigator.
Martian Dry Ice Gliders

Glaciers move, or flow, downhill due to gravity and the internal deformation of ice on Earth. It is not the same when there is dry ice (frozen carbon dioxide). NASA research indicates hunks of frozen carbon dioxide -- dry ice -- may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing furrows as they go. Researchers deduced this process could explain one enigmatic class of gullies seen on Martian sand dunes by examining images from NASA's Mars Reconnaissance Orbiter (MRO) and performing experiments on sand dunes in Utah and California.
The Flesh of Ancient Fish
June 13, 2013 03:26 PM - Andy Soos, ENN
It is hard to tell from just bones or a fossilized rock what a creature once looked like with muscles. Flesh does not survive well over the eons. Swedish, Australian and French researchers have presented for the first time miraculously preserved musculature of 380 million year old armored fish discovered in north-west Australia. This research will help scientists to better understand how neck and abdominal muscles evolved during the transition from jawless to jawed vertebrates. The scientific paper describing the discovery is published in the journal Science. The team of scientists who studied the fossilized fish was jointly directed by Prof. Kate Trinajstic, Curtin University, Perth, Australia and Prof. Per Erik Ahlberg of Uppsala University Sweden.
Better Land Use May Help Protect Coral Reefs

According to new research, for nations that have outlying coral reefs, better land use of the mainland is crucial in order to prevent further damage to these ocean habitats. A recent study reveals important implications for Madagascan and Australian reefs based on deforestation scenarios.
Odd Martian Thermal Rhythm
June 13, 2013 09:46 AM - Andy Soos, ENN
Researchers using NASA's Mars Reconnaissance Orbiter have found that temperatures in the Martian atmosphere regularly rise and fall not just once each day, but twice. "We see a temperature maximum in the middle of the day, but we also see a temperature maximum a little after midnight," said Armin Kleinboehl of NASA's Jet Propulsion Laboratory in Pasadena, Calif., who is the lead author of a new report on these findings. Temperatures swing by as much as 58 degrees Fahrenheit (32 kelvins) in this odd, twice-a-day pattern, as detected by the orbiter's Mars Climate Sounder instrument.
Shale and Where it Lies
June 12, 2013 12:54 PM - Andy Soos, ENN
Shale oil is a rapidly developing source of oil and natural gas. Where does it lie? Estimated shale oil and shale gas resources in the United States and in 137 shale formations in 41 other countries represent 10% of the world's crude oil and 32% of the world's natural gas technically recoverable resources, or those that can be produced using current technology without reference to economic profitability, according to a new report released today by the U.S. Energy Information Administration (EIA). More than half of the identified shale oil resources outside the United States are concentrated in four countries--Russia, China, Argentina and Libya--while more than half of the non-U.S. shale gas resources are concentrated in five countries--China, Argentina, Algeria, Canada, and Mexico. The United States would be ranked second after Russia for shale oil resources and fourth after Algeria for shale gas resources if compared with the 41 countries assessed

New fossil shines light on primate and human evolution
June 12, 2013 09:47 AM - Allison Winter, ENN
A 55 million year old fossil that has been unearthed from an ancient lakebed in China's Hubei Province has revealed a pivotal event in primate and human evolution. Hailing from the early Eocene Epoch, the fossil is crucial to the branch split that led to anthropoids (monkeys, apes, and humans) on one side, and living tarsiers (small, tree-dwelling nocturnal primates) on the other. The discovered fossil represents a previously unknown genus and species named Archicebus Achilles.
