When a research team asked cocaine addicts to choose, hypothetically, between money now or cocaine of greater value later, "preference was almost exclusively for the money now," said Warren K., Bickel, professor in the Virginia Tech Carilion Research Institute, director of the Advanced Recovery Research Center, and professor of psychology in the College of Science at Virginia Tech. This result is significantly different from previous studies where a subject chooses between some money now or more money later. Hollywood portrays cocaine addicts as people who will do anything ...

The work of molecular biologist Joseph M. Miano, Ph.D., and clinician Craig Benson, M.D., seems worlds apart: Miano helps head the Aab Cardiovascular Research Institute and Benson is chief resident of the combined Internal Medicine and Pediatrics program at the University of Rochester Medical Center. Though the chance of their professional paths crossing was highly unlikely, shared enthusiasm, intense curiosity and a little detective work led to a unique collaboration and important new insights on the inner workings of the human genome. Together, Miano and Benson created ...

Critical Information Network (CiNet), LLC, announces the release of its newly updated Electrical 1 training series designed to help companies improve the electrical maintenance practices of workers and meet the demands of today's busy training manager. According to OSHA and the National Fire Protection Association (NFPA), electrical accidents and the resulting fires cause millions of dollars in damages, countless injuries and life threatening workplace events every year. The tragedy is that many of these could have been avoided by simple maintenance repairs supported ...

(WASHINGTON, August 11, 2011) – According to a study published in Blood, the Journal of the American Society of Hematology (ASH), researchers have reported that administration of granulocyte colony-stimulating factor (G-CSF), a drug that releases stem cells from the bone marrow into the blood, is unlikely to put healthy stem cell donors at risk for later development of abnormalities involving loss or gains of chromosomes that have been linked to hematologic disorders such as myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). G-CSF therapy is given to healthy ...

While many Britons enjoyed the recent heatwave, taking the chance to lie back and top up their tans, for others it only served to heighten their fears of damp armpits and clammy hands. As a result, Transform Cosmetic Surgery Group recorded a 45% surge in enquiries into use of BOTOX injections a treatment for excessive sweating over a three-day period of the heatwave as the nation become more perspiration-conscious. Known as hyperhidrosis, the condition sees sweat glands become overactive, something often made worse during periods of hot weather. During the procedure, ...

By isolating cells from patients' spinal tissue within a few days after death, researchers funded by the National Institutes of Health have developed a new model of the paralyzing disease amyotrophic lateral sclerosis (ALS). They found that during the disease, cells called astrocytes become toxic to nerve cells – a result previously found in animal models but not in humans. The new model could be used to investigate many more questions about ALS, also known as Lou Gehrig's disease. ALS can run in families, but in the majority of cases, it is sporadic, with no known ...

(Santa Barbara, Calif.) –– Viruses fill the ocean and have a significant effect on ocean biology, specifically marine microbiology, according to a professor of biology at UC Santa Barbara and his collaborators. Craig A. Carlson, professor with UCSB's Department of Ecology, Evolution, and Marine Biology, is the senior author of a study of marine viruses published this week by the International Society for Microbial Ecology Journal, of the Nature Publishing Group. The new findings, resulting from a decade of research, reveal striking recurring patterns of marine virioplankton ...

PASADENA, Calif.— Like scars that remain on the skin long after a wound has healed, earthquake fault lines can be traced on Earth's surface long after their initial rupture. Typically, this line of intersection between the area where the fault slips and the ground is more complicated at the surface than at depth. But a new study of the April 4, 2010, El Mayor–Cucapah earthquake in Mexico reveals a reversal of this trend. While the fault involved in the event appeared to be superficially straight, the fault zone is warped and complicated at depth. The study—led by researchers ...

MADISON, WI, JULY 11, 2011 -- Although phosphorus is an essential nutrient for all life forms, essential amounts of the chemical element can cause water quality problems in rivers, lakes, and coastal zones. High concentrations of phosphorus in aquatic ecosystems are often associated with human activities in the surrounding area, such as agriculture and urban development. However, relationships between specific human sources of phosphorus and phosphorus concentrations in aquatic ecosystems are yet to be understood. Establishing these relationships could allow for the development, ...

WHAT:Pyrazinamide has been used in combination with other drugs as a first-line treatment for people with tuberculosis (TB) since the 1950s, but exactly how the drug works has not been well understood. Now, researchers have discovered a key reason why the drug effectively shortens the required duration of TB therapy. The finding potentially paves the way for the development of new drugs that can help eliminate TB in an infected individual even more rapidly. The study was supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National ...

In 1991, Carl Lewis was both the fastest man on earth and a profound long jumper, perhaps the greatest track-and-field star of all time in the prime of his career. On June 14th of that year, however, Carl Lewis was human. Leroy Burrell blazed through the 100-meters, besting him by a razor-thin margin of three-hundredths of a second. In the time it takes the shutter to capture a single frame of video, Lewis's three-year-old world record was gone. In a paper just published in the journal Neuron, a team at the Stanford School of Engineering, led by electrical engineers Krishna ...

PITTSBURGH—The transport system inside living cells is a well-oiled machine with tiny protein motors hauling chromosomes, neurotransmitters and other vital cargo around the cell. These molecular motors are responsible for a variety of critical transport jobs, but they are not always on the go. They can put themselves into "energy save mode" to conserve cellular fuel and, as a consequence, control what gets moved around the cell, and when. A new study from Carnegie Mellon University and the Beatson Institute for Cancer Research published in the Aug. 12 issue of Science ...

A federal judge in the United States District Court for the Middle District of Florida has ruled that Florida drug crime laws violated a defendant's due process rights. At issue was whether prosecutors must prove that an accused drug trafficker had knowledge of drug possession, which is a fundamental legal principle in American criminal justice and the common law that preceded it. Amendments to Florida's criminal code in 2002 removed the mens rea requirement from the Drug Abuse Prevention and Control law. The term is Latin for "guilty mind" and is best summed ...

August 11, 2011 (Aurora, CO)--In an article published online this week in Nature Genetics, a University of Colorado Cancer Center team in partnership with universities in China and Denmark reports the first genetic sequencing of urothelial (transitional) carcinoma, the most prevalent type of bladder cancer. Recognizing the genetic mutations that make bladder cancer cells different than their healthy neighbors may allow early genetic screenings for cancer and new therapies targeting cells with these mutations. In addition, the mutations the team found are similar to those ...

PITTSBURGH—A growing number of illegal online pharmacies are flooding the web trying to sell dangerous unauthorized prescriptions, according to a new report from cybersecurity experts at Carnegie Mellon University. Report authors Nicolas Christin, associate director of the Information Networking Institute (INI) and a senior systems scientist at the INI and CyLab along with Nektarios Leontiadis from the Department of Engineering and Public Policy (EPP), and Tyler Moore from Wellesley College, found that rogue websites were redirecting consumers to illicit pharmacies. ...

LOMA LINDA, Calif. – While some past studies have shown that persons carrying a few extra pounds in their 70s live longer than their thinner counterparts, a new study that measured subjects' weight at multiple points over a longer period of time reveals the opposite. Research from Adventist Health Studies recently published in the Journal of the American Geriatrics Society showed that men over 75 with a body mass index (BMI) greater than 22.3 had a 3.7-year shorter life expectancy, and women over 75 with a BMI greater than 27.4 had a 2.1-year shorter life expectancy. ...

A study on the effect of different alcoholic beverages and drinking behaviour on the risk of acute pancreatitis was conducted, using the Swedish Mammography Cohort and Cohort of Swedish Men, to study the association between consumption of spirits, wine and beer and the risk of acute pancreatitis. In total, 84,601 individuals, aged 46-84 years, were followed for a median of 10 years, of whom 513 developed acute pancreatitis. There was a dose–response association between the amount of spirits consumed on a single occasion and the risk of acute pancreatitis. After multivariable ...

Sexual assault charges can bring tremendous notoriety and an immediate risk to the accused offender's freedom. Law enforcement gives cases involving rape, child molestation, indecent assault and other sex crimes focused attention, and the police often rush to apprehend a suspect if the victim does not personally know the alleged assailant. This means that anyone matching the description given by the victim will be at risk for being accused and charged with the crime, particularly if that person is at the wrong place at the wrong time. Such was the case when a so-called ...

For nearly 60 years, Pyrazinamide (PZA) has been used in conjunction with other medications to treat tuberculosis (TB), but scientists did not fully understand how the drug killed TB bacteria. PZA plays a unique role in shortening the duration of current TB therapy to six months and is used frequently to treat multi-drug resistant TB. A new study, led by researchers at the Johns Hopkins Bloomberg School of Public Health, suggests that PZA binds to a specific protein named RpsA and inhibits trans-translation, a process that enables the TB bacteria to survive under stressful ...

DURHAM, N.C. – Duke engineers have already shown that they can "cloak" light and sound, making objects invisible -- now, they have demonstrated the theoretical ability to significantly increase the efficiency of ships by tricking the surrounding water into staying still. "Ships expend a great deal of energy pushing the water around them out of the way as they move forward," said Yaroslav Urzhumov, assistant research professor in electrical and computer engineering at Duke's Pratt School of Engineering. "What our cloak accomplishes is that it reduces the mass of fluid ...

It has been just over a year since the Upper Big Branch mine disaster in West Virginia killed 29 miners, and the federal Mine Safety and Health Administration (MSHA) has come out with proposed coal mining safety rule revisions. The proposal is intended to ensure that underground coal mine operators find and fix violations of mandatory health or safety standards, with an overall goal of improving miner health and safety. This comes as MSHA releases the findings from its yearlong investigation of the Upper Big Branch mine explosion. MSHA assistant secretary Joseph A. Main ...

Many small-business owners think their choice is between having in-house counsel or employing outside counsel for their legal needs. The fear inherent to this line of thinking is that, in reality, the choice becomes one of expensive in-house counsel or no legal counsel at all. However, a middle ground exists to provide solutions for a variety of business sizes and needs: outsourced in-house counsel services. Almost all Business Decisions Have Legal Implications When you are running your own business, to say you are busy is usually an understatement. From day-to-day ...

MADISON, WI, AUGUST 11, 2011 -- Recent studies report that corn hybrids released in the late 2000s, especially Bt hybrids, require higher seeding rates than commercial hybrids released in the 1990s to reach maximum yields. Expectedly, corn seeding rates in the USA have increased significantly in the past 10 years. However, limited data is available on silage yield and quality responses of recently released hybrids to seeding rates. Cornell scientist William Cox investigated the response of eight hybrids (three Bt and a non-Bt hybrid, two brown midrib and two silage specific ...

One of the earliest lessons in science that students learn is that a ray or beam of light travels in a straight line. Students also learn that light rays fan out or diffract as they travel. Recently it was discovered that light rays can travel without diffraction in a curved arc in free space. These rays of light were dubbed "Airy beams," after the English astronomer Sir George Biddell Airy, who studied what appears to be the parabolic trajectory of light in a rainbow. Now, scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) have demonstrated the ...
