Sophie Holles, a PhD researcher at the University of Bristol and one of the study's authors, said: "Natural underwater sound is used by many animals to find suitable habitat, and traffic noise is one of the most widespread pollutants. If settlement is disrupted by boat traffic, the resilience of habitats like reefs could be affected."

Cattle grazing and clean water can coexist on national forest lands, according to research by the University of California, Davis.
The study, published today in the journal PLOS ONE, is the most comprehensive examination of water quality on National Forest public grazing lands to date.
COLUMBUS, Ohio – Higher levels of omega-3 fatty acids in the blood may reduce the risk for hip fractures in postmenopausal women, recent research suggests.
Scientists analyzed red blood cell samples from women with and without a history of having a broken hip. The study showed that higher levels of omega-3 fatty acids from both plant and fish sources in those blood cells were associated with a lower likelihood of having fractured a hip.
As rapidly increasing demand for bandwidth strains the Internet's capacity, a team of engineers has devised a new fiber optic technology that promises to increase bandwidth dramatically. The new technology could enable Internet providers to offer much greater connectivity – from decreased network congestion to on-demand video streaming.
AUSTIN, Texas – By creating a small electrical field that removes salts from seawater, chemists at The University of Texas at Austin and the University of Marburg in Germany have introduced a new method for the desalination of seawater that consumes less energy and is dramatically simpler than conventional techniques. The new method requires so little energy that it can run on a store-bought battery.
The process evades the problems confronting current desalination methods by eliminating the need for a membrane and by separating salt from water at a microscale.
Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have developed a new method for visualizing material defects in thin-film solar cells.
Ulsan, South Korea-- A research team at Ulsan National Institute of Science and Technology (UNIST), S. Korea, found a new physical organogel electrolyte with two unique characteristics: an irreversible thermal gelation and a high value of the Li+ transference number.
A Recent fire on a Boeing 787 on the ground in Boston, US, was caused by a battery failure, it resulted in the release of flammable electrolytes, heat damage and smoke. If they had used a safer electrolyte, the risk would have been reduced.
LIVERMORE, Calif.— Providing auxiliary hydrogen power to docked or anchored ships may soon be added to the list of ways in which hydrogen fuel cells can provide efficient, emissions-free energy.
DURHAM, N.C. -- Imagine downloading a NetFlix app to your phone so that you can watch movies on the go. You would expect the app to request your account's username and password the first time it runs. Most apps do.
HOUSTON – (June 26, 2013) – Adults with a disability are more likely to be obese or extremely obese than those without a disability according to a study led by researchers at The University of Texas School of Public Health, which is part of The University of Texas Health Science Center at Houston (UTHealth).
A business may build a better reputation as a good corporate citizen by donating $100,000 to ten charities, as opposed to $1million to one charity, suggested University of Missouri anthropologist Shane Macfarlan. Contrary to earlier assumptions in theoretical biology, Macfarlan's research found that helping a greater number of people builds a positive reputation more than helping a few people many times. The results of this research can offer guidance to businesses and politicians on how to improve their public images.
CAMBRIDGE, Mass- Most efforts at improving solar cells have focused on increasing the efficiency of their energy conversion, or on lowering the cost of manufacturing. But now MIT researchers are opening another avenue for improvement, aiming to produce the thinnest and most lightweight solar panels possible.
Such panels, which have the potential to surpass any substance other than reactor-grade uranium in terms of energy produced per pound of material, could be made from stacked sheets of one-molecule-thick materials such as graphene or molybdenum disulfide.
Efforts to overcome the challenges of mechanics, cost and image clarity are viewed as a crucial step in efforts to tame the THz gap since imaging and sensing at this frequency holds the potential for advances in areas as divergent as chemical fingerprinting, security imaging of hidden weapons, even real-time skin imaging to promote simple detection of skin cancer.
Central to this challenge is the development of a technology to create efficient masks – similar to the aperture of a camera -- capable of tuning THz radiation in order to produce clear images in just a few seconds.
The Energy Department's National Renewable Energy Lab has announced a world record of 31.1% conversion efficiency for a two-junction solar cell under one sun of illumination.
NREL Scientist Myles Steiner announced the new record June 19 at the 39th IEEE Photovoltaic Specialists Conference in Tampa, Fla. The previous record of 30.8% efficiency was held by Alta Devices.
WASHINGTON -- Diluted bitumen has no greater likelihood of accidental pipeline release than other crude oils, says a new report from the National Research Council. The committee that wrote the report found that diluted bitumen has physical and chemical properties within the range of other crude oils and that no aspect of its transportation by pipeline would make it more likely than other crude oils to cause an accidental release. The committee was not asked to address whether the consequences of a diluted bitumen release differ from those of other crude oils.
