The more honesty and humility an employee may have, the higher their job performance, as rated by the employees' supervisor. That's the new finding from a Baylor University study that found the honesty-humility personality trait was a unique predictor of job performance. "Researchers already know that integrity can predict job performance and what we are saying here is that humility and honesty are also major components in that," said Dr. Wade Rowatt, associate professor of psychology and neuroscience at Baylor, who helped lead the study. "This study shows that those ...

Fossilized bones discovered in Texas from a flying reptile that died 89 million years ago may be the earliest occurrence in the world of the prehistoric creature known as Pteranodon. Previously, Pteranodon bones have been found in Kansas, South Dakota and Wyoming in the Niobrara and Pierre geological formations. This likely Pteranodon specimen is the first of its kind found in Texas, according to paleontologist Timothy S. Myers at Southern Methodist University, Dallas, who identified the reptile. The specimen was discovered north of Dallas by an amateur fossil hunter ...

DALLAS – March 1, 2011 – Researchers at UT Southwestern Medical Center have identified a signaling pathway in the brain that's sufficient to induce cellular leptin resistance, a problem that decreases the body's ability to "hear" that it is full and should stop eating. "Leptin resistance is a significant factor, yet the mechanisms that underlie the problem remain unclear," said Dr. Joel Elmquist, professor of internal medicine and pharmacology at UT Southwestern and senior author of the study appearing in the March issue of Cell Metabolism. "The fact that this cellular ...

ROCHESTER, Minn. -- Recent Accreditation Council for Graduate Medical Education (ACGME) limits aimed to enhance patient safety may compromise the quality of doctors' training, according to a study by Mayo Clinic researchers published in the March issue of Mayo Clinic Proceedings (http://www.mayoclinicproceedings.com). Patient safety has long been a critical concern for hospitals, in particular for those training new doctors. Since 1984, when the death of 24-year-old Libby Zion at a New York hospital was attributed to an overtired medical resident, training programs have ...

GREENSBURG, PA—March 1, 2011— Imagine that you witness a crime. The police investigator brings you to the police station to obtain an official statement, but between the crime and your official witness statement, you are exposed to other (potentially inaccurate) information about the crime. Before administering the criminal interview, the investigator asks you a litany of mundane demographic questions in a dry and uninterested manner, then moves directly into the interview about the crime. Would you feel comfortable? Most importantly, would your report be accurate and detailed, ...

MADISON, WI, MARCH 1, 2011 – Methane is an extremely potent greenhouse gas. Wetlands, gas hydrates, permafrost, termites, oceans, freshwater bodies, non-wetland soils, are all natural sources of atmospheric methane; however, the majority of methane presence ca n be accredited to human-related activities. These activities include: such as fossil fuel production, biomass burning, waste management and animal husbandry. The release of methane into the atmosphere by cattle and other large grazing mammals is estimated to account for 12 to 17% of the total global methane release. Recently, ...

Scientists now have a better understanding of why spider silk fibers are so incredibly strong. Recent research, published by Cell Press on February 15th in Biophysical Journal, describes the architecture of silk fibers from the atomic level up and reveals new information about the molecular structure that underlies the amazing mechanical characteristics of this fascinating natural material.

WEST LAFAYETTE, Ind. - A Purdue University researcher is leading an effort to create a new scientific field that will use sound as a way to understand the ecological characteristics of a landscape and to reconnect people with the importance of natural sounds. Soundscape ecology, as it's being called, will focus on what sounds can tell people about an area. Bryan Pijanowski, an associate professor of forestry and natural resources and lead author of a paper outlining the field in the journal BioScience, said natural sound could be used like a canary in a coal mine. Sound ...

CHAMPAIGN, lll. — A review of more than 160 studies of human and animal subjects has found "clear and compelling evidence" that – all else being equal – happy people tend to live longer and experience better health than their unhappy peers. The study, in the journal Applied Psychology: Health and Well-Being, is the most comprehensive review so far of the evidence linking happiness to health outcomes. Its lead author, University of Illinois professor emeritus of psychology Ed Diener, who also is a senior scientist for the Gallup Organization, of Princeton, N.J., analyzed ...

Alcoholism is a tough addiction to kick. Eventually, most people return to drinking. But some Dutch and German psychological scientists have tested a short-term regime that promises to help alcoholics stay sober. Their study is published in Psychological Science, a journal of the Association of Psychological Science. Heavy drinkers tend to behave impulsively in response to temptation. Meanwhile, their "reflective," or controlled, responses—the thoughts that would help them resist drinking—are often weak. Most therapies, including Cognitive Behavior Therapy, primarily ...

Mild heart failure patients with a particular condition that results in disorganized electrical activity throughout the heart benefit substantially from cardiac resynchronization therapy with defibrillator (CRT–D), according to a study published in the American Heart Association journal Circulation. In patients with the condition, known as left bundle branch block or LBBB, CRT-D therapy reduced heart failure progression and the risk of ventricular tachyarrhythmias, fast and potentially life-threatening heart rhythms. Heart failure patients without LBBB did not receive ...

Many people suffer from a devastating condition known as critical limb ischemia (CLI) that can lead to muscle wasting and even amputation. The disease is linked to the blockage of blood flow to the skeletal muscle and current treatment options include rehabilitative exercise and surgical bypass of blood vessels. New preclinical research suggests there may be a way to restore blood supply in skeletal muscle without traditional intervention. Scientists at The University of Texas Health Science Center at Houston (UTHealth) and the Salk Institute for Biological Studies ...

An AIDS vaccine tested in people, but found to be ineffective, influenced the genetic makeup of the virus that slipped past. The findings suggest new ideas for developing HIV vaccines. The results were published Feb. 27 in Nature Medicine. This is the first evidence that vaccine-induced cellular immune responses against HIV-1 infection exert selective pressure on the virus. "Selective pressure" refers to environmental demands that favor certain genetic traits over others. The senior author of the multi-institutional study is Dr. James I. Mullins, University of Washington ...

Tropical Cyclone Atu had a brief but memorable life last week, and NASA's Atmospheric Infrared Sounder (AIRS) instrument that flies aboard NASA's Aqua satellite captured a day-by-day look at its growth and death. AIRS provides infrared images of atmospheric phenomena, oceans and land areas around the world. Basically, infrared data takes the temperature of these things. When NASA's Aqua satellite flew over Tropical Cyclone Atu from February 21 through the 25 it saw thunderstorm cloud tops grow colder as the clouds grew higher and thunderstorms became more powerful. When ...

WASHINGTON -- NASA's Glory spacecraft is scheduled for launch on Friday, March 4. Technical issues with ground support equipment for the Taurus XL launch vehicle led to the scrub of the original Feb. 23 launch attempt. Those issues have been resolved. The March 4 liftoff from Vandenberg Air Force Base, Calif., is targeted for 5:09:43 a.m. EST, in the middle of a 48-second launch window. Spacecraft separation occurs 13 minutes after launch. Data from the Glory mission will allow scientists to better understand how the sun and tiny atmospheric particles called aerosols ...

INDIANAPOLIS – Tanning bed exposure can produce more than some tanners may bargain for, especially when they self-diagnose and use the radiation to treat skin eruptions, according to research conducted by the Indiana University School of Medicine Department of Dermatology. "There are many reasons to be cautious of tanning bed radiation but some people use tanning beds to 'self-treat' skin eruptions," said Jeffrey B. Travers, M.D., Ph.D., senior author of a study published online in the Archives of Dermatology. "If the skin eruption is eczema or even psoriasis, a tanning ...

Indiana University scientists have solved a perplexing mystery regarding one of the body's main energy storage molecules, in the process shedding light on a possible route to treatment of a rare but deadly disease in teenagers. The disease occurs when a genetic mutation causes excessive amounts of phosphate to build up in glycogen. Glycogen is a chain-like molecule the body uses to temporarily store glucose when it's not needed to provide energy for cellular activities. The excess phosphate causes unnatural glycogen structures to appear in the body, including the brain, ...

BUFFALO, N.Y. -- When a disaster's physical evidence is gone -- debris removed, shooter arrested, ashes cold -- the psychological effects of the disaster on emergency responders and civilians involved still may burn. Emergency mental health, a field often overlooked in the chaos, is a vital component of any disaster response, but may not be well represented in emergency preparedness planning. Trained mental health responders to the Continental Flight 3407 disaster outside Buffalo in 2009 share their lessons learned on mental health preparedness in an article that ...

Guojun Liu has discovered a way to use nanotechnology to reduce friction in automobile engines and machines. "The technology should be useful in a wide range of machineries other than automobile engines," says Dr. Liu, a professor in the Department of Chemistry and an expert in polymer synthesis. "If implemented industrially, this nanotechnology should help prolong machine life and improve energy efficiency." Dr Liu's team prepared miniscule polymer particles that were only tens of nanometers in size. These particles were then dispersed in automobile engine base oils. ...

This press release is available in German. Many materials, when observed over a sufficiently long period of time, show changes in their mechanical properties. The exact course of these developments depends on the underlying microscopic mechanisms. However, the microscopic structure and the complexity of the systems make direct observation extremely difficult. That is why a team led by Professor Andreas Bausch from the Chair of Cellular Biophysics resorted to a model system that can be precisely controlled using actin filaments, a biopolymer that, among other things, ...

The spiral galaxy NGC 247 is one of the closest spiral galaxies of the southern sky. In this new view from the Wide Field Imager on the MPG/ESO 2.2-metre telescope in Chile large numbers of the galaxy's component stars are clearly resolved and many glowing pink clouds of hydrogen, marking regions of active star formation, can be made out in the loose and ragged spiral arms. NGC 247 is part of the Sculptor Group, a collection of galaxies associated with the Sculptor Galaxy (NGC 253, also shown in eso0902 - http://www.eso.org/public/news/eso0902/ - and eso1025 - http://www.eso.org/public/news/eso1025/). ...

Existing plans for antiviral and antibiotic use during a severe influenza pandemic could reduce wastewater treatment efficiency prior to discharge into receiving rivers, resulting in water quality deterioration at drinking water abstraction points. These conclusions are published this week (2 March 2011) in a new paper in the journal Environmental Health Perspectives, which reports on a study designed to assess the ecotoxicologic risks of a pandemic influenza medical response. The research was carried out by a team from the Centre for Ecology & Hydrology (UK), the Institute ...

Experts agree that long-term alcohol abuse is detrimental to memory function and can cause neuro-degenerative disease. However, according to a study published in Age and Ageing by Oxford University Press today, there is evidence that light-to-moderate alcohol consumption may decrease the risk of cognitive decline or dementia. Estimates from various studies have suggested the prevalence of alcohol-related dementia to be about 10% of all cases of dementia. Now researchers have found after analyzing 23 longitudinal studies of subjects aged 65 years and older that the impact ...
