One Product, Two Prices: The Border Effect in Retail Prices
In a recent paper by Economists Messner, Rumler, and Strasser (Messner et al. 2023), they examined the effect of national borders on grocery prices in the highly integrated border region of Austria and Germany. This provides a good case study for understanding the effect of the law of one price in the trade of physical goods and the factors that influence it.
Learning from Silicon Valley Bank's Uninsured Deposit Run
In a recent article originally written by Enrico Perotti, he pointed out that the public bailout for cash-rich companies holding large deposits in the failed Silicon Valley Bank has made clear that society is still at the mercy of uninsured demandable claims. This article proposes that a combination of gating and swing pricing when outflows become large to be applied to any uninsured demandable claim.
New Psychology Research Sheds Light on The Cognitive Mechanisms Underlying Loneliness
In a recent article originally written by Eric W. Dolan, he introduced an experiment of researchers who aimed to investigate how different levels of closeness and familiarity affect memory encoding and how this is related to loneliness. The results showed that feeling lonely is related to a self-referential memory bias, which might make people feel like they are more distant from their friends.
Testing the Visual Mandela Effect
In a recent article originally written by David Ludden, he introduced research that tested the visual Mandela Effect. The research conducted 3 experiments. The research results showed that schema theory is one of the causes but it can not explain all situations.
Solving Crimes with Math: Busting Criminal Networks
In a recent article originally written by Marcia Gomez, she introduced three measures of centrality to understanding who would be the most important criminal in a network. In this article, math and network theory, also known as graph theory, are used to identify key players in organized crimes, such as terrorist attacks. Investigators analyze social networks using the notion of centrality to detect the relative importance of each criminal in the network.
The Infinity Tree: Representing Infinities of Real Numbers with Countably Infinite Tree Structures
This paper discusses how the infinite set of real numbers between 0 and 1 could be represented by a countably infinite tree structure which would avoid Cantor's diagonalization argument that the set of real numbers is not countably infinite. Likewise, countably infinite tree structures could represent all real numbers, and all points in any number of dimensions in multi-dimensional spaces.
A Not-So-Brief History of British Coronations
The coronation is a significant part of British history. After the death of Queen Elizabeth II, Prince Charles will succeed to the throne. Understanding the history of British coronations also helps us understand how Britain has changed and developed over the centuries. This article provides a general understanding of the process of coronations and a further understanding of the political and religious significance of coronations in Britain.
The Hippodrome of Constantinople
The arena was not only a space for sporting events but also a place where important festivals and imperial punishments were held. The color factions of the Hippodrome were an essential aspect of the communal identity of Constantinople, and their rivalry carried significant social and political consequences. The Hippodrome's decline and eventual dismantling reflect the broader arc of medieval cultural decline and the emergence of modernity.
Saint Francis of Assisi Review- A Saint for All Seasons
In a recent article by columnist Laura Cumming, she wrote a review about Saint Francis of Assisi. There are countless seventeenth- and eighteenth-century depictions of Saint Francis of Assisi and a musical angel in churches and museums throughout Western Europe. The titles of these depictions vary widely, at times describing Francis as "consoled", "comforted", in "ecstasy" or in "rapture". The author has depicted a saint of all seasons in this article and introduced varied paintings of this saint.
From Picasso and Hokusai's Prussian Blue to Vermeer's Shade of Red: A History of Art in 7 Colours
This article provides a fascinating exploration of the history and meaning behind the colours used in some of the most famous works of art. By understanding the origins and context of each colour, readers can gain a deeper appreciation of the masterpieces they are used in.
How to Make Low-Carbon Concrete From Old Cement
This article informs readers about a possible solution to the issue of carbon emissions caused by cement production. It highlights a new product, zero-emissions cement, which is made from recycled, old cement from demolished buildings, thus significantly reducing the carbon footprint associated with traditional cement-making.
Catalyst Transforms Carbon Dioxide into Sustainable Byproduct
This article highlights an innovative way to convert captured carbon into products with established markets using electrochemistry. The researchers have successfully created acetic acid out of carbon monoxide derived from captured carbon and have shown the potential to improve economic appeal and sustainable production. Learning about this process is significant because it could spur new interest in carbon capture and storage, and also has the potential to reduce carbon emissions by providing alternative methods for creating industrial chemicals like acetic acid.
Scientists Achieve a Breakthrough in Nuclear Fusion.
In a recent article by columnist Michael Greshko, he threw out the challenge of nuclear reaction in the first place and then briefly introduced how the reaction took place. In this article, the author pointed out the main task in generating nuclear energy, which is net energy gain.
Researchers Have Created an Edible, Rechargeable Battery that Could Power a Small Electronic Device.
In a recent article by Anna Napolitano, she wrote an article about edible and rechargeable battery. In her article, scientists from the Italian Institute of Technology have created the first edible, rechargeable battery using food-derived materials to improve the safety and efficiency of diagnosing and treating gastrointestinal tract ailments and other wearable applications.
We Thought We Knew Turtles. A New Discovery Raises a Mystery
While freshwater turtles usually rest on stationary objects to warm their bodies in the sun, the research shows that turtles around the world bask at night, suggesting that they can regulate their temperatures and use nocturnal basking to cool off when water is too hot.
Octopus, Squid and Cuttlefish Arms Evolved to 'Taste' Different Compounds
In a recent article by Tina Hesman Saey who worked for Science News and as a writer, she recently write a break-through research about Octopus, squid and cuttlefish. In this article she suggested that octopuses, squid and cuttlefish use different sets of proteins in detecting taste through their tentacles.
Methane May not Warm the Earth Quite As Much As Previously Thought
The new study has found that methane, a potent greenhouse gas that has its highest warming effect through absorbing longwave infrared radiation, can also absorb shortwave radiation from the sun in the upper atmosphere, leading to a reduction in its overall warming effect of about 30%.
Tidal Power Faces a Fickle Future with Rising Seas
This article highlights the potential impact of sea level rise on tidal power generation. As the world looks for cleaner energy sources, tidal power has great potential, but only in locations with fast currents or sizable sea level swings. This article details how sea level rise due to climate change threatens to reduce the viability of potential tidal power sites by removing their potential for fast currents or appropriate tidal ranges.
