Featured Report: Oil Spill Cleanup in Arctic Requires Increased Infrastructure

April 23, 2014 1:00 pm | by National Research Council | Comments

A changing climate is increasing the accessibility of U.S. Arctic waters to commercial activities such as shipping, oil and gas development and tourism. That’s raising concerns about the risk of oil spills. Now, a report says a full suite of proven oil response tools is needed to address potential oil spills in U.S. Arctic waters, but not all of them are readily available.


How to Avoid Fracking Industry Water Woes

April 23, 2014 12:03 pm | by ACS | Comments

The shale gas boom has transformed the energy landscape in the U.S., but in some drier locations, it could cause conflict among the energy industry, residents and agricultural interests over already-scarce water resources.


Physicist Demonstrates How the OED Was Wrong

April 23, 2014 12:00 pm | by Queensland Univ. of Technology | Comments

In 2010, a physicist spotted a mistake in the prestigious Oxford English Dictionary that had gone unnoticed for 99 years. The OED incorrectly described atmospheric pressure, rather than gravity, as the operating force in a siphon. Now, he has proven the mistake by demonstrating the science of siphons.


Google Maps Enables Time Traveling

April 23, 2014 12:00 pm | by Associated Press, Michael Liedtke | Comments

Trips down memory lane are now available on Google's digital maps. The new twist on time travel is debuting as part of the "Street View" feature in Google's maps, a navigational tool that attracts more than 1 billion visitors each month.


Man Among First in U.S. to Get Bionic Eye

April 23, 2014 12:00 pm | by Associated Press, Mike Householder | Comments

Diagnosed with retinitis pigmentosa as a teenager, Roger Pontz has been almost completely blind for years. Now, thanks to a high-tech procedure that involved the surgical implantation of a "bionic eye," he's regained enough of his sight to catch small glimpses of his wife, grandson and cat.


Magnify the Body to Shrink Pain

April 23, 2014 12:00 pm | by Inside Science News Service, Cynthia McKelvey | Comments

The perceived size of your hand affects how intensely your hand feels pain, according to an experiment in which participants were subjected to a pinprick-like sensation on one fingertip while a lens modified the size of the hand receiving the painful stimulus.


For Deer, Iron Curtain Still Separates Europe

April 23, 2014 12:00 pm | by Associated Press, Karel Janicek | Comments

The Iron Curtain was traced by an electrified barbed-wire fence that isolated the communist world from the West. Deer still balk at crossing the border with Germany even though the physical fence came down a quarter century ago.


Cloaked DNA Devices Survive Mission

April 23, 2014 12:00 pm | by Wyss Institute for Biologically Inspired Engineering | Comments

It's a familiar trope in science fiction: in enemy territory, activate your cloaking device. Real-world viruses use similar tactics to make themselves invisible to the immune system. Now, scientists have mimicked these viral tactics to build the first DNA nanodevices that survive the body's immune defenses.


Updated Patenting Guide Needed for Biotech

April 23, 2014 12:00 pm | by Rice Univ. | Comments

Biotechnology scientists must be aware of the broad patent landscape and push for new patent and licensing guidelines.


Big Data Approach IDs New Mammalian Clock Gene

April 23, 2014 7:00 am | by Perelman School of Medicine at the Univ. of Pennsylvania | Comments

To accelerate clock-gene discovery, investigators are using a computer-assisted approach to identify and rank candidate clock components. The approach found a new core clock gene.


Space Observatory Spies Rare Pair of Black Holes

April 23, 2014 7:00 am | by European Space Agency | Comments

A pair of supermassive black holes in orbit around one another have been spotted by the X-ray Multi-Mirror Mission. This is the first time such a pair have been seen in an ordinary galaxy. They were discovered because they ripped apart a star when the space observatory happened to be looking in their direction.


Graphene, Nanotubes Pair for Ultracapacitors

April 23, 2014 7:00 am | by American Institute of Physics | Comments

By combining the powers of two single-atom-thick carbon structures, researchers have created a new ultracapacitor that is both high performance and low cost. The device capitalizes on the synergy brought by mixing graphene flakes with single-walled carbon nanotubes, two carbon nanostructures with complementary properties.


‘Nanoreporters’ Gather Intel on Oil Prior to Pumping

April 23, 2014 7:00 am | by Rice Univ. | Comments

Scientists have created a nanoscale detector that checks for and reports on the presence of hydrogen sulfide in crude oil and natural gas while they’re still in the ground.


People More Aware of Upper Half of Field of Vision

April 23, 2014 7:00 am | by North Carolina State Univ. | Comments

A new study has found that people pay more attention to the upper half of their field of vision. This discovery could have ramifications for everything from traffic signs to software interface design.
