China Olympics Traffic Measures Cut Carbon Emissions

A new NASA-funded study of the impacts of China’s traffic restrictions for the 2008 Summer Olympics in Beijing shows how widespread changes in transportation patterns could greatly reduce the threat of climate change.

New research by an international team of scientists led by the National Center for Atmospheric Research (NCAR), Boulder, Colo., indicates that China’s restrictions on motor vehicles designed to improve air quality during the games had the side benefit of dramatically cutting emissions of carbon dioxide by between 26,500 and 106,000 U.S. tons (24,000 and 96,000 metric tons) during the event.

How to Become a Bounty Hunter

Bounty hunting, or the practice of apprehending fugitives for a monetary reward, is often something that conjures up images of men or women who operates outside of the law and bring criminals to justice through legally ambiguous means. In reality however, bounty hunting, also known as skip tracing, is a necessary part of the modern criminal justice system in the United States. This article will serve as a basic explanation of how bounty hunters operate, their purpose in society and their basic day-to-day operations in bringing those who fail to appear in court to justice through legal means.

As a profession bounty hunting is something that is often romanticized by movies and other media. However, the job is actually a fairly technical and adheres to the same stringent due process laws that cops and courts are subject to. Bounty hunting is also a profession that depends on a thorough knowledge of laws and legal precedent, something that often requires a college-level education that many overlook. (more…)

Exeter Physicist Bends Light Waves on Surfboards

A University of Exeter scientist is bringing together his passions for Physics and surfing with research that could inspire a host of new technologies. Dr Matt Lockyear is using foam from inside surfboards to make materials that can manipulate light.

Scientists across the globe are trying to develop materials that can refract light to create ‘invisibility cloaks’, which are of particular interest to the aerospace industry. ‘Invisibility cloaking’ means building properties into a material that allow the device to guide light waves around an object, making it invisible.

Deadly E. coli Strain Decoded

EAST LANSING, Mich. — The secret to the deadly 2011 E. coli outbreak in Germany has been decoded, thanks to research conducted at Michigan State University.

The deadliest E. coli outbreak ever, which caused 54 deaths and sickened more than 3,800 people, was traced to a particularly virulent strain that researchers had never seen in an outbreak before. In the current issue of the academic journal PLoS ONE, a team of researchers led by Shannon Manning, MSU molecular biologist and epidemiologist, suggests a way to potentially tame the killer bacteria.

Public Sightings Suggest Increase in Basking Sharks in British Waters

The number of basking sharks recorded in Britain’s seas could be increasing, decades after being protected from commercial hunting in the late 20th century.

The most comprehensive analysis ever undertaken of basking shark sightings in UK waters, by the University of Exeter, the Marine Conservation Society (MCS), Cornwall Wildlife Trust (CWT) and Wave Action, is published in  the journal Marine Ecology Progress Series.

The northeast Atlantic hosted an extensive commercial fishery for basking sharks, mainly in Norway, Ireland and Scotland, where more than 81,000 were killed between 1952 and 2004, hunted largely for their liver oil. Large-scale hunting ended in the UK in the middle of the twentieth century, though it continued at low levels in Norway until 2000. (more…)

Experiments Inform Study of Crowd Motion

To determine how crowd behavior emerges from individual actions, William Warren, professor of cognitive, linguistic, and psychological sciences, assembled his own crowds and engaged them in an unusual four-day experiment in Sayles Hall. The subjects were equipped with motion capture markers affixed like antennae to bike helmets.

PROVIDENCE, R.I. [Brown University] — What must the staid-faced University luminaries in those portraits around Sayles Hall have thought while they watched this scene play out for four days last week? Over and over, two to 20 young men and women in bike helmets adorned with what appeared to be five large antennae walked back and forth across a cardboard-covered floor. En route to goals marked by numbers just beneath the portraits, they dodged each other and arrangements of cardboard pillars. Each time they generated patterns of foot traffic. (more…)

Scientists studying ocean currents and oil spills with large-scale experiment

Scientists are releasing hundreds of floating GPS devices into the Gulf of Mexico this week near the Deepwater Horizon site to study the role of ocean currents in oil spills. The experiment is the largest in scale of its kind, deploying 300 satellite-tracked, untethered buoys, called drifters, over the course of two and a half weeks.

“We’re trying to use the drifters as a simulation of an oil spill,” said Dennis Kirwan, Mary A.S. Lighthipe Professor of Marine Studies in the University of Delaware’s College of Earth, Ocean, and Environment. “This is a big event in oceanography.” (more…)
