PASADENA, Calif.—In an earthquake, ground motion is the result of waves emitted when the two sides of a fault move—or slip—rapidly past each other, with an average relative speed of about three feet per second. Not all fault segments move so quickly, however—some slip slowly, through a process called creep, and are considered to be "stable," or not capable of hosting rapid earthquake-producing slip. One common hypothesis suggests that such creeping fault behavior is persistent over time, with currently stable segments acting as barriers to fast-slipping, shake-producing ...

A new image released today reveals how Gemini Observatory's most advanced adaptive optics (AO) system will help astronomers study the universe with an unprecedented level of clarity and detail by removing distortions due to the Earth's atmosphere. The photo, featuring an area on the outskirts of the famous Orion Nebula, illustrates the instrument's significant advancements over previous-generation AO systems. "The combination of a constellation of five laser guide stars with multiple deformable mirrors allows us to expand significantly on what has previously been possible ...

Rochester, MN, January 9, 2013 – Microscopic amounts of blood in urine have been considered a risk factor for urinary tract malignant tumors. However, only a small proportion of patients referred for investigation are subsequently found to have cancer. A new Kaiser Permanente Southern California study published in the February Mayo Clinic Proceedings reports on the development and testing of a Hematuria Risk Index to predict cancer risk. This could potentially lead to significant reductions in the number of unnecessary evaluations. Individuals with microscopic hematuria ...

Some retailers, such as Apple's iTunes, are known for using uniform pricing in an effort to simplify consumers' choices and perhaps increase their tendency to make impulse purchases. But other stores, like supermarkets, often have small price differences across product flavors and brands. As counterintuitive as it might seem, these small price differences may actually make the options seem more similar, according to new research published in Psychological Science, a journal of the Association for Psychological Science. The research shows that adding small differences ...

COLUMBIA, Mo. –Parenting infants and toddlers can be challenging, and for generations, mothers have turned to other moms for advice. Now, with the availability of the Internet, mothers are consulting each other using modern venues: online message boards. Research from the University of Missouri indicates online discussion boards provide safe environments for mothers to anonymously express child-rearing concerns and receive support from other moms. "Mothers have feelings that they might be embarrassed to talk about face-to-face with someone," said Jean Ispa, professor ...

TORONTO, ON – Ecologists at the University of Toronto and the Swiss Federal Institute of Technology Zurich (ETH Zurich) have found that, given time, invading exotic plants will likely eliminate native plants growing in the wild despite recent reports to the contrary. A study published in Proceedings of the National Academy of Sciences (PNAS) reports that recent statements that invasive plants are not problematic are often based on incomplete information, with insufficient time having passed to observe the full effect of invasions on native biodiversity. "The impacts ...

ALBUQUERQUE, N.M. — Sandia National Laboratories Truman Fellow Anne Ruffing has engineered two strains of cyanobacteria to produce free fatty acids, a precursor to liquid fuels, but she has also found that the process cuts the bacteria's production potential. Micro-algal fuels might be one way to reduce the nation's dependence on foreign energy. Such fuels would be renewable since they are powered by sunlight. They also could reduce carbon dioxide emissions since they use photosynthesis, and they could create jobs in a new industry. President Barack Obama, speaking in ...

A high-fiber diet may have the clinical potential to control the progression of prostate cancer in patients diagnosed in early stages of the disease. The rate of prostate cancer occurrence in Asian cultures is similar to the rate in Western cultures, but in the West, prostate cancer tends to progress, whereas in Asian cultures it does not. Why? A University of Colorado Cancer Center study published in the January 2013 issue of the journal Cancer Prevention Research shows that the answer may be a high-fiber diet. The study compared mice fed with of inositol hexaphosphate ...

Research by University of Arizona astronomy professor Rodger Thompson finds that a popular alternative to Albert Einstein's theory for the acceleration of the expansion of the universe does not fit newly obtained data on a fundamental constant, the proton to electron mass ratio. Thompson's findings, reported Jan. 9 at the American Astronomical Society meeting in Long Beach, Calif., impact our understanding of the universe and point to a new direction for the further study of its accelerating expansion. To explain the acceleration of the expansion of the universe, astrophysicists ...

UNIVERSITY PARK, Pa. -- Living in a caring community may help curb teenage alcohol use, while hanging out with antisocial peers can have the opposite effect, according to Penn State researchers studying substance abuse patterns. The researchers evaluated how seven different categories of risk and protective factors predicted teen alcohol use. Risk factors included antisocial attitudes, antisocial behaviors, association with antisocial peers and family risk. Protective factors were positive community experiences, positive school experiences and family strengths. Damon ...

UNIVERSITY PARK, Pa. -- Mussels can be a mouthwatering meal, but the chemistry that lets mussels stick to underwater surfaces may also provide a highly adhesive wound closure and more effective healing from surgery. In recent decades bioahesives, tissue sealants and hemostatic agents became the favored products to control bleeding and promote tissue healing after surgery. However, many of them have side effects or other problems, including an inability to perform well on wet tissue. "To solve this medical problem, we looked at nature," said Jian Yang, associate professor ...

How Do Alabama Courts Make Child Custody Decisions? When parents split up, one of the most contentious issues is often who will get custody of the children. Often, both parents believe they know what is best for their children, but they may not agree with one another on the matter. When parents cannot reach an arrangement for themselves, the court steps in and decides for them. Parents in Alabama should be aware of the types of custody arrangements available in the state and how courts reach custody decisions. Types of Child Custody in Alabama There are two types ...

Head Cold & Ear Trauma to Flight Crew Members "Never fly with a head cold." For flight crews in the commercial airline industry, this time-honored warning is difficult to follow and too often ignored. As the pressure to fulfill employment obligations mounts, airline flight personnel often feel the need to push themselves into the air when their stuffed-up head is telling them to stay on the ground. While, arguably, such decisions to go to work and "tough it out" may show an heroic commitment to the good old American work ethic, the ultimate physical ...

Massachusetts Law Regarding Moving Out-of-State With Your Children In this fast-paced modern world, it is an unfortunate reality that families are broken up by events such as job relocations or divorce. Often this means that children must move and make a new home outside of the commonwealth. Despite the common occurrence of this arrangement, there are laws in Massachusetts that govern the removal of minor children from the Commonwealth. It is therefore important for Massachusetts parents, whether divorced or married, who are considering taking their child with them ...

Injured Service Members Fight to Find Employment In this tough economy, employers have the luxury of choosing from a large pool of highly qualified candidates, which can make finding a good position for any applicant difficult. Even with these obstacles, one would expect a candidate that can claim strong communication, problem solving, resilience, collaboration and conflict resolution skills on a resume to stand out from the crowd -- especially when these attributes, common skills gained by service members in any branch of the military, can also be confirmed by reputable ...

Car accidents and traumatic brain injury One serious and devastating possible result of a car accident is a traumatic brain injury. In fact, over half of all reported traumatic brain injuries are the result of a car accident. Traumatic brain injuries occur from any force that penetrates or fractures the skull. Therefore, the skull does not necessarily need to be fractured in a car accident for a TBI to occur. The brain may collide against the internal skull bone from the force of the accident, which can cause bruising or bleeding inside the brain that is not apparent ...

Swimming Pools Can be a Grave Danger to Younger Children As in other warm-weather states, swimming pools are a common fixture in Texas. Besides serving as a means to cool off on hot Texas afternoons, pools also can attract young children and can be dangerous for them. All too often, toddlers as well as older kids can move so quickly that they can make it to the family or a neighbor's pool before an adult knows that they are gone. It is a sad fact that young children can drown in a few seconds and may not make any noise, such a splashing or screaming, that would alert ...

New Jersey Bill Seeks to Toughen Penalties for DUI with a Minor Passenger As it is nationwide, driving while under the influence of alcohol in New Jersey is a serious problem. In addition to his or her own life, an impaired driver can put other lives at risk--sometimes innocent children who are passengers in the car. A recently introduced New Jersey bill aims to address this problem by increasing the penalties for adults who drive drunk with children in the car. The bill is sponsored by Charles Mainor, the Assembly Law and Public Safety Chairman. Under existing New ...

Are teens the only ones liable for their car accidents? The National Highway Traffic Safety Administration reports that car accidents are the leading cause of death for teenagers. Three thousand teens die in car accidents every year in the U.S., and one in five 16-year-olds has a car accident in their first year as a new driver. A parent's liability for the teen's driving California generally requires parental consent for a teen under the age of 18 to drive. This consent creates the potential for parental liability for any injuries caused by their teen in a car ...
