The study suggests that consumers who pay for preferential treatment will have faster loading times, while those who don't may experience slower speeds.
Research suggests that superfluous choices at early stages of purchase can lead to increased customer satisfaction, as consumers perceive greater deliberation and fluency in decision-making. This results in higher repeat business rates and brand loyalty.
A team of researchers is exploring how polybrominated diphenyl ethers (PBDEs) affect fat storage and production in laboratory rats. Preliminary data suggests that chronic exposure to PBDEs may cause insulin resistance, a precursor to Type II diabetes.
Researchers at Texas A&M University have identified a specific protein transport process involved in a rare form of early blindness, known as choroideremia. The study suggests that therapies targeting the neighboring retinal pigment epithelium (RPE) may rescue photoreceptor loss and even reverse the disease.
Researchers at Salk Institute find epidermis controls plant growth signals, allowing them to manipulate growth pathways. Dwarf Arabidopsis plants that lack BRI1 receptor expression are made larger by driving its expression in the outer layer.
Brookhaven researchers have learned how to grow better samples of LBCO, allowing for extensive studies on its properties. The study reveals that the high-temperature superconductor has distinct insulating-like properties and a characteristic energy gap.
Researchers at Rensselaer Polytechnic Institute have identified a bacterium that can dechlorinate polychlorinated biphenyls (PCBs) in situ, eliminating the need for dredging. The Dehalococcoides bacteria thrive on PCBs, replacing chlorines with hydrogen to initiate degradation.
Researchers found that high long-chain omega-3 intake is associated with increased grey matter volume in areas of the brain related to emotional arousal and regulation. This study suggests that omega-3s may promote structural improvements in brain regions linked to mood disorders.
A new study from the University of Chicago Press Journals reveals that we tend to pay more attention to disappointment than to positive experiences. The researchers found that when consumers feel better than expected, they take it for granted and don't evaluate their experience as well.
Plant researchers Sigal Savaldi-Goldstein and Joanne Chory have uncovered the mechanism behind plant growth, showing that the epidermis is the driving force behind cell expansion. The study, published in Nature, reveals a previously unknown mode of communication between shoot tissues.
The current US child health system is a patchwork of disconnected programs and lacks clear accountability or performance goals. The authors argue that the system fails to produce desired health outcomes due to outdated logic and finance strategies.
Astronomers have observed Z Cam binary system exhibiting a massive shell of gas and dust surrounding the white dwarf, indicating a classical nova explosion. The discovery supports a 20-year-old theory suggesting double-star systems cycle between blast types.
A team of researchers has identified more than 70 markers unique to ovarian tumor blood vessels, which could lead to new screening and treatment tools. The finding suggests that these markers may be a sign of an aggressive tumor and could help inform treatment decisions.
Scientists return to Cenote Zacatón to resume tests of the NASA-funded robot DEPTHX, designed to survey and explore for life in one of Earth's most extreme regions. The probe may hold clues to life in outer space and on Earth's ice-bound polar lakes.
Most individuals with acute myeloid leukemia (AML) express CDX2, a protein regulating HOX family genes. Reducing CDX2 levels decreases AML cell proliferation, supporting its causal role in leukemogenesis.
A study published in the Journal of Consumer Research found that individuals who exercise self-control by dieting or resisting thoughts are more prone to making impulse purchases. This is because their self-regulatory resources can be depleted, leading to increased spending on tempting items.
A team of international researchers has found an asteroid whose rotation speed increases due to re-radiation of solar energy from its surface. The study confirms that non-gravitational forces play a crucial role in asteroid evolution and could potentially affect asteroid collisions with Earth.
A recent study from Journal of Consumer Research found that people who bought unexpected items felt happy and a little guilty, while those who resisted the impulse purchase felt proud. Marketers can use this knowledge to create more effective advertising strategies by understanding consumers' emotions after recent purchases.
