Here's one way that old-fashioned newsprint beats the Internet. Tulane University scientists have discovered a novel bacterial strain, dubbed "TU-103," that can use paper to produce butanol, a biofuel that can serve as a substitute for gasoline. They are currently experimenting with old editions of the Times Picayune, New Orleans' venerable daily newspaper, with great success. TU-103 is the first bacterial strain from nature that produces 
butanol directly from cellulose, an organic compound. "Cellulose is found in all green plants, and is the most abundant organic ...

CHICAGO –Thanks to a new diagnostic imaging technique, physicians now have an objective test to evaluate patients for parkinsonian syndromes, such as Parkinson's disease. Northwestern Memorial Hospital is among the first institutions in the country to offer DaTscan™, the only FDA-approved imaging agent for assessment of movement disorders. Until now, there were no definitive tests to identify the disease, forcing physicians to rely on clinical examinations to make a diagnosis. This technology allows doctors to differentiate Parkinson's from other movement disorders. "The ...

Oil well control is one of the most important processes during drilling operations. In deepwater drilling, controlling pressure in the oil well is crucial, as excessive pressures in the drilled hole can result in blowouts, leading to disastrous events like the 2010 Gulf of Mexico Oil Spill. The deeper the well, the higher the pressure, and the higher the risks associated with tapping oil from wells. During drilling, when the pressure applied to balance the hydrocarbon pressure in a well is not great enough to overcome that exerted by gas and fluids in the rock formation ...

The old fashioned method of exchanging contact details via printed business cards would appear to be one of the most effective means of creating long lasting customer relations. The way in which companies do business is constantly evolving particularly as a result of advances in technology. Increasingly, business communications are being carried out electronically. Despite this migration, it would seem that there will always be a place for the printed business card. The basic purpose of the business card design is to provide a business's or individual's contact details. ...

WASHINGTON — An analysis of more than 1,000 research articles concluded that few health problems are caused by or clearly associated with vaccines. A committee of experts convened by the Institute of Medicine to review the scientific literature on possible adverse effects of vaccines found convincing evidence of 14 health outcomes -- including seizures, inflammation of the brain, and fainting -- that can be caused by certain vaccines, although these outcomes occur rarely. It also found indicative though less clear data on associations between specific vaccines and four ...

In the waters off the North Carolina coast, historically-significant World War II submarines and shipwrecks rest on the seafloor, a testament to a relatively unknown chapter in U.S. history. According to a new NOAA report, the shipwrecks are not only important for their cultural value, but also as habitat for a wide diversity of fishes, invertebrates and algal species. Additionally, due to their unique location within an important area for biological productivity, the shipwrecks are potential sites for examining community change. In June 2010, scientists conducted biological ...

After returning from holiday, it's likely you felt that the journey home by plane, car or train went much quicker than the outward journey, even though in fact both distances and journey are usually the same. So why the difference? According to a new study by Niels van de Ven and his colleagues it seems that many people find that, when taking a trip, the way back seems shorter. Their findings, published online in Springer's Psychonomic Bulletin & Review, suggest that this effect is caused by the different expectations we have, rather than being more familiar with the route ...

August 25, 2011 -- Two new studies have found that smokers who tend to take their first cigarette soon after they wake up in the morning may have a higher risk of developing lung and head and neck cancers than smokers who refrain from lighting up right away. The findings by researchers at Columbia University's Mailman School of Public Health and Penn State College of Medicine may help identify smokers who have an especially high risk of developing cancer and would benefit from targeted smoking interventions to reduce their risk. The research was published early online ...

WASHINGTON, D.C. – At its public meeting on August 29 in Washington, the Presidential Commission for the Study of Bioethical Issues will publicly discuss several key findings as it refines the conclusions of its historical investigation into the U.S. Public Health Service (U.S. PHS) studies done in Guatemala in the 1940s. The U.S. PHS research involved intentionally exposing and infecting vulnerable populations to sexually transmitted diseases. The Commission's historical investigation is due to President Obama in September. Following the revelation last fall that the ...

Researchers at the National Institutes of Health have created a mathematical model – and an accompanying online weight simulation tool – of what happens when people of varying weights, diets and exercise habits try to change their weight. The findings challenge the commonly held belief that eating 3,500 fewer calories – or burning them off exercising – will always result in a pound of weight loss. Instead, the researchers' computer simulations indicate that this assumption overestimates weight loss because it fails to account for how metabolism changes. The computer ...

Considered the sequel to the already popular Isis video slot game, Multi-Player Isis has just launched to a great deal of fanfare at Platinum Play Australian Casino.

Some might view this as the competitive edge they need and others might simply find it interesting to see how other players are enjoying the game. Either way, this new feature is very different ...

The incidence of malaria in many African countries south of the Sahara is falling rapidly. A Danish-Tanzanian research group has discovered that the mosquito carrying the malaria parasite has practically disappeared from villages without organized mosquito control, and the researchers do not know why. There are several hypotheses but without proper data they cannot say whether malaria is being eradicated or whether it is just resting up before returning with renewed vigour. "Many of our fellow malaria researchers think that the fall in countries such as Tanzania, Eritrea, ...

The expression "beauty's only skin-deep" has often been applied to the chemistry of materials because so much action takes place at the surface. However, for many of the materials in today's high technologies, such as semiconductors and superconductors, once a device is fabricated it is the electronic structures below the surface, in the bulk of the material or in buried layers, that determine its effectiveness. For the past 30 years, one of the most valuable and widely used techniques for studying electronic structures has been ARPES – Angle-Resolved PhotoEmission Spectroscopy. ...

A well-preserved fossil discovered in northeast China provides new information about the earliest ancestors of most of today's mammal species--the placental mammals. According to a paper published today in the journal Nature, the fossil represents a new milestone in mammal evolution that was reached 35 million years earlier than previously thought. It fills an important gap in the fossil record and helps to calibrate modern, DNA-based methods of dating evolution. The paper, by a team of scientists led by Carnegie Museum of Natural History paleontologist Zhe-Xi Luo, ...

CHAMPAIGN, lll. — Researchers have engineered new sensors that fluoresce in the presence of compounds that interact with estrogen receptors in human cells. The sensors detect natural or human-made substances that alter estrogenic signaling in the body. The study appears in the journal Biotechnology and Bioengineering. Estrogen occurs naturally in the body (in the form of 17-beta-estradiol), and a variety of plants (such as soybeans), pharmaceuticals, microbial byproducts and industrial chemicals (such as bisphenol A, in plastics) are also known to activate or block ...

Boston, MA – The global obesity epidemic has been escalating for decades, yet long-term prevention efforts have barely begun and are inadequate, according to a new paper from international public health experts published in the August 25, 2011 edition of the journal The Lancet. Noting that many countries lack basic population-wide data on children's weight and height, the authors call on governments around the world to launch a coordinated effort to monitor, prevent, and control obesity, and the long-term health, social and economic costs associated with it. The paper ...

A galaxy with a combination of characteristics never seen before is giving astronomers a tantalizing peek at processes they believe played key roles in the growth of galaxies and clusters of galaxies early in the history of the Universe. The galaxy, dubbed Speca by the researchers, is only the second spiral, as opposed to elliptical, galaxy known to produce large, powerful jets of subatomic particles moving at nearly the speed of light. It also is one of only two galaxies to show that such activity occurred in three separate episodes. Giant jets of superfast particles ...
