Everybody loves freebies, whether it's a tasty treat handed out at the supermarket or a month of Netflix. These campaigns are a great way to bring attention to a new product or service, and marketers use them to target new customers and grow their customer base.
But offering free trials to existing customers might seem like a waste of time, after all, your customers are already sold on your product.
Global food production is incredibly efficient, and the world's farmers produce enough to feed the global population. Despite this abundance, a quarter of the global population do not have regular access to sufficient and nutritious food. A growing and more affluent population will further increase the global demand for food and create stresses on land, for example, through deforestation.
Prof. LI Chuanfeng, XU Jinshi, and XU Xiaoye from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), collaborating with Prof. CHEN Jingling from Nankai University, realized the non-contacing exchange of the polarization of two photons, revealing the unique quantum characteristics of the "Quantum Cheshire Cat".
The study, published in Nature Communications, deepens the understanding of the fundamental problem of physics, "what is physical reality."
Earth's geographical surfaces have been formed over millions of years, and various current theories aim to explain their formation. The most popular theory, called the "plate tectonics theory," states that Earth's outermost layer is a dynamic system consisting of slowly moving plates, also known as "tectonic" plates. As theses plates move, they come close to each other and collide, or drift away from or slide past the other, causing tension or rupture along their boundaries. If two colliding plates face enormous compression force along the rupture line, a slab of the earth would uplift.
Researchers at the Max Delbrück Center for Molecular Medicine in the Helmholtz Association (MDC) developed a mouse model that enables them to look inside a working muscle and identify the proteins that allow the sarcomere to contract, relax, communicate its energy needs, and adapt to exercise. Specifically, they were able to map proteins in defined subregions of the sarcomere, starting from the "Z-disc," the boundary between neighboring sarcomeres. This in and of itself was a significant step forward in the study of striated muscle.
New research from the University of Cincinnati shows kidney failure resulting from acute kidney injury (AKI) leads to a higher risk of death in the first six months compared to kidney failure from diabetes or other causes and that risk is even higher for women.
AKI occurs when kidneys stop working properly and can range from minor loss of kidney function to complete failure. AKI often happens as a complication of another serious illness. The UC study highlights the need for developing customizable treatment strategies targeting factors that enhance kidney recovery.
(Boston)--In an effort to improve the survival of patients with myeloproliferative neoplasms, a type of leukemia, researchers inhibited a specific protein (alpha5beta1 integrin) to decrease the number of large bone marrow cells (megakaryocytes) in an experimental model. An increase in megakaryocyte numbers is thought to be the cause of many problems observed in this disease. This type of treatment approach has never been attempted before.
Higher rates of severe COVID-19 infections in Black, Asian and Minority Ethnic (BAME) populations are not explained by socioeconomic or behavioral factors, cardiovascular disease risk, or by vitamin D status, according to new research led by Queen Mary University of London.
The findings, published in the Journal of Public Health, suggest that the relationship between COVID-19 infection and ethnicity is complex, and requires more dedicated research to explain the factors driving these patterns.
TROY, N.Y. -- A team of researchers led by Sufei Shi, an assistant professor of chemical and biological engineering at Rensselaer Polytechnic Institute, has uncovered new information about the mass of individual components that make up a promising quasiparticle, known as an exciton, that could play a critical role in future applications for quantum computing, improved memory storage, and more efficient energy conversion.
AUSTIN, Texas － During the next year, the Food and Drug Administration will review many new drug applications for preventing and treating the new coronavirus. But early approvals could get delayed by the standards the agency used for older drugs, according to new research from the McCombs School of Business at The University of Texas at Austin.
Wind farms are large, highly technical projects but their development often relies on personal decisions made by individual landowners and small communities. Recognizing the power of the human element in wind farm planning, Stanford University researchers have devised a model that considers how interactions between developers and landowners affect the success and cost of wind farms.
CLEMSON, South Carolina - A Clemson University scientist has joined forces with an international team of astronomers to identify periodic gamma-ray emissions from 11 active galaxies, paving the way for future studies of unconventional galaxies that might harbor two supermassive black holes at their centers.
Among astronomers, it has long been well-established that most galaxies host a black hole at their center. But galaxies hosting a pair of black holes has remained theoretical.
Searching for food at night can be tricky. To find prey in the dark, bats use echolocation, their "sixth sense." But to find food faster, some species, like Molossus molossus, may search within hearing distance of their echolocating group members, sharing information about where food patches are located. Social information encoded in their echolocation calls may facilitate this foraging strategy, according to a recent study by Smithsonian Tropical Research Institute (STRI) scientists and collaborating institutions published online in Behavioral Ecology.
Researchers from North Carolina State University have discovered that teaching physics to neural networks enables those networks to better adapt to chaos within their environment. The work has implications for improved artificial intelligence (AI) applications ranging from medical diagnostics to automated drone piloting.
HUNTINGTON, W.Va. - A new study led by Marshall University researcher M. Jeremiah Matson found that environmental conditions affect the stability of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in human nasal mucus and sputum.
