Television commercials for luxury vehicles pack a lot in their 30-second running times: the camera offers quick shots of the soft leather upholstery, the shiny colors, the state-of-the-art entertainment system, and the four-wheel drive. But these multiple angles and shifting perspectives have a negative impact on consumer evaluation of products, according to a new study from a Tel Aviv University researcher. TAU's Dr. Yael Steinhart and her collaborators Yuwei Jiang of Hong Kong Polytechnic University, Rashmi Adaval of Hong Kong University of Science and Technology, and ...

Imagine that you have a cup of coffee and sit down to read People magazine. How long do you think the energy boost will last before you reach for another cup? Would you need more caffeine if you tried to read War and Peace? A new study in the Journal of Consumer Research finds that consumers wrongly believe that pharmacological products such as coffee and aspirin lose their effectiveness when they engage in more strenuous activities. "People make assumptions about how long it takes for products to wear off. For example, they know that cars burn gasoline more quickly ...

Have you ever received a request for help and wondered how deserving the recipients are of your donation? This way of thinking may seem inconsistent with your moral values, especially if you consider yourself an otherwise compassionate and empathic person. A new study in the Journal of Consumer Research suggests that moral identity decreases donations when recipients are deemed to be responsible for their plight. "Our research examines how moral values of empathy and justice have distinct influences on people when they are asked to make donations benefiting others whose ...

Have you found yourself at a fancy restaurant trying to impress new friends or in a foreign country and unsure of what to order? Not wanting to appear foolish, you just go along with everyone else. According to a new study in the Journal of Consumer Research, we're more likely to copy other people's choices when we lack social acceptance or enough information to make an informed decision. "We suggest that when someone is deciding between options for which their preferences are not well formed, observing the choice of another consumer makes the option chosen by the other ...

Dartmouth scientists and their colleagues have devised a breakthrough laser that uses a single artificial atom to generate and emit particles of light. The laser may play a crucial role in the development of quantum computers, which are predicted to eventually outperform today's most powerful supercomputers. The study appears in the journal Physical Review B. The new laser is the first to rely exclusively on superconducting electron pairs. "The fact that we use only superconducting pairs is what makes our work so significant," says Alex Rimberg, a professor of physics ...

(Boston)-- Researchers from Boston University School of Medicine (BUSM) and Boston Medical Center (BMC) have found that participants who received care through BMC's Violence Intervention Advocacy Program (VIAP)--an interventional program targeting the physical, mental, emotional and social needs of violently injured youths—were less likely to retaliate for their injuries and experienced life changing behaviors through connections to caring, steady, supportive adults who helped them feel trust and hope. These findings are reported in the journal Academic Emergency Medicine. ...

How would a child respond to this question? Would his or her list be full of relatives, animals from movies and books, or perhaps neighborhood pets? Would the poppies blooming on the front steps make the list or the oak tree towering over the backyard? How might the animals children name compare to those named by children raised in a different cultural or language background or in a community that offers more direct contact with the natural world? In a study conducted by Andrea Taverna of the Consejo Nacional de Investigaciones Científicas y Técnicas (Formosa, Argentina) ...

Highly purified crystals that split light with uncanny precision are key parts of high-powered lenses, specialized optics and, potentially, computers that manipulate light instead of electricity. But producing these crystals by current techniques, such as etching them with a precise beam of electrons, is often extremely difficult and expensive. Now, researchers at Princeton and Columbia universities have proposed a new method that could allow scientists to customize and grow these specialized materials, known as photonic crystals, with relative ease. "Our results point ...

Infrared data gathered on the tropical low pressure area known as System 92L gave forecasters a hint that the low would become the Atlantic Ocean hurricane season's second tropical depression. NASA's Aqua satellite passed over System 92L on July 21 at 11:53 a.m. EDT and the Atmospheric Infrared Sounder (AIRS) instrument gathered infrared data on the developing low pressure area. The infrared data shows temperature, and AIRS data showed some areas of very cold cloud top temperatures, exceeding the threshold of -63F/-52C that indicates cloud tops near the top of the troposphere. ...

Vibrate a solution of rod-shaped metal nanoparticles in water with ultrasound and they'll spin around their long axes like tiny drill bits. Why? No one yet knows exactly. But researchers at the National Institute of Standards and Technology (NIST) have clocked their speed—and it's fast. At up to 150,000 revolutions per minute, these nanomotors rotate 10 times faster than any nanoscale object submerged in liquid ever reported. The discovery of this dizzying rate has opened up the possibility that they could be used not only for moving around inside the body—the impetus ...

Astronomers using the NASA/ESA Hubble Space Telescope have probed the extreme outskirts of the stunning elliptical galaxy Centaurus A. The galaxy's halo of stars has been found to extend much further from the galaxy's centre than expected and the stars within this halo seem to be surprisingly rich in heavy elements. This is the most remote portion of an elliptical galaxy ever to have been explored. There is more to a galaxy than first meets the eye. Extending far beyond the bright glow of a galaxy's centre, the swirling spiral arms, or the elliptical fuzz, is an extra ...

BOSTON -- Open a child's lunch box and you're likely to find that the lunches and snacks inside fall short of federal guidelines. Those are the findings of a study conducted by researchers at the Friedman School of Nutrition Science and Policy at Tufts University and in the Department of Public Health and Community Medicine at Tufts University School of Medicine. The findings are published online ahead of print in the Journal of the Academy of Nutrition and Dietetics. Led by senior author Jeanne Goldberg, Ph.D., R.D., a professor at the Friedman School, the study is ...

The darker side of meerkats – which sees them prevent their daughters from breeding, and kill their grandchildren – is explained in a new study. Research into the desert creatures – which live in groups with a dominant breeding pair and many adult helpers – shows that the alpha female can flourish when it maintains the sole right to breed. The study shows how this way of life, also found in many animals such as ants and bees, can prove effective despite its sinister side. Dominant meerkats control breeding within their group through violence, by banishing any other ...

The challenges faced by researchers in modifying properties of nanomaterials for application in devices may be addressed by a simple technique, thanks to recent innovative studies conducted by scientists from the National University of Singapore (NUS). Through the use of a simple, efficient and low cost technique involving a focused laser beam, two NUS research teams, led by Professor Sow Chorng Haur from the Department of Physics at the NUS Faculty of Science, demonstrated that the properties of two different types of materials can be controlled and modified, and consequently, ...

Researchers from the University of Murcia have studied the changes in the brain that are associated with impulsiveness, a personality trait that causes difficulties in inhibiting a response in the face of a stimulus and leads to unplanned actions without considering the negative consequences. These patterns can serve as an indicator for predicting the risk of behavioural problems. A new study headed by researchers from the University of Murcia analyses whether the connectivity of an infant's brain is related to children's impulsiveness. "Impulsiveness is a risk factor ...

From telephone numbers to foreign vocabulary, our brains hold a seemingly endless supply of information. However, as we are getting older, our ability to learn and remember new things declines. A team of scientists around Associate Prof Dr Antonio Del Sol Mesa from the Luxembourg Centre for Systems Biomedicine of the University of Luxembourg and Dr Ronald van Kesteren of the VU University Amsterdam have identified the molecular mechanisms of this cognitive decline using latest high-throughput proteomics and statistical methods. The results were published this week in the ...

This news release is available in French. Tel Aviv/Halle, Saale. The drinking water resources on the eastern, Jordanian side of the Dead Sea could decline severe as a result of climate change than those on the western, Israeli and Palestinian side. This is the conclusion reached by an international team of researchers that calculated the water flows around the Dead Sea. The natural replenishment rate of groundwater will reduce dramatically in the future if precipitation lowers as predicted, say the scientists, writing in the journal Science of the Total Environment. ...

New Rochelle, NY -- Stem cells offer much promise for treating damaged organs and tissues, but with current transplantation approaches stem cell survival is poor, limiting their effectiveness. New methods are being developed and tested to improve the survival and optimize their therapeutic function after transplantation, as described in a Review article in BioResearch Open Access, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the BioResearch Open Access website. In the article 'Preconditioning Stem Cells for In Vivo ...

DURHAM, N.C. – In a cost-effectiveness analysis of commercial diet programs and pills, the Weight Watchers program and the drug Qsymia showed the best value for the money. The Jenny Craig regimen generated the greatest weight loss, but was also the most expensive option tested, according to researchers at Duke-National University of Singapore (NUS) Graduate Medical School. The findings, published in the June issue of the journal Obesity, provide important information on the health and weight-loss benefits per dollar spent as insurance carriers consider coverage for weight ...

Say you are out clothes shopping and you spot something that brings you back to a special time from your childhood when you were surrounded by friends and family. Suddenly, you find yourself purchasing an expensive shirt that makes you feel like a kid again. According to a new study in the Journal of Consumer Research, we're more likely to spend money when we're feeling nostalgic. "We wondered why nostalgia is so commonplace in marketing. One reason could be that feeling nostalgic weakens a person's desire for money. In other words, someone might be more likely to buy ...

At some point, most kids will hear that drinking milk helps make their bones strong or that fish is food for the brain. But do these messages foster the idea that if something is good for us, it must surely taste bad? According to a new study in the Journal of Consumer Research, when children hear about the benefits of healthy food, they're less likely to eat it. "We predicted that when food is presented to children as making them strong or as a tool to achieve a goal such as learning how to read or count, they would conclude the food is not as tasty and therefore consume ...

Graduating from college is an important life event often attributed to being smart and working hard. Many people celebrate this milestone achievement by buying themselves an expensive gift or taking a dream vacation. A new study in the Journal of Consumer Research shows that consumers who attribute their successes to internal character traits rather than hard work are more likely to select unique products. "We found that consumers who attribute feelings of pride to their unique character traits—rather than how hard they worked to accomplish something—are more likely to ...

Hypoxia-inducible factor 1 (HIF-1) attenuates amyloid-beta protein neurotoxicity and decreases apoptosis induced by oxidative stress or hypoxia in cortical neurons. Prof. Xiqing Chai and co-workers from Hebei Chemical and Pharmaceutical College, China constructed a recombinant adeno-associated virus (rAAV) vector expressing the human HIF-1α gene (rAAV-HIF-1α) efficiently, and tested the assumption that rAAV-HIF-1α represses hippocampal neuronal apoptosis induced by amyloid-beta protein. Their results confirmed that rAAV-HIF-1α significantly reduces apoptosis ...

Previous findings have demonstrated that acupuncture at the Taixi (KI3) acupoint in healthy youths can activate neurons in cognitive-related cerebral cortex. In a perspective article released in the Neural Regeneration Research (Vol. 9, No. 11, 2014), Dr. Shangjie Chen and co-workers at Baoan Hospital, Southern Medical University, China investigated whether acupuncture at this acupoint in elderly patients with mild cognitive impairment (MCI) can also activate neurons in these regions. Researchers revealed that under resting state and task-related functional magnetic resonance ...

Cranial radiotherapy is one of the most important therapeutic methods for the treatment of various types of primary and metastatic brain tumors. Although conventional photon irradiation has significantly improved the treatment of cancer, the central nervous system is prone to damage after high-dose irradiation, resulting in severe delayed or progressive nervous tissue injury. The issues regarding brain radiation injury have been widely discussed, and recent investigations have emphasized changes in pathomorphology. However, the underlying mechanism remains in debate. Researchers ...
