Microfluidic devices are an innovative technology that overcomes the limitations of traditional two-dimensional experiments by culturing cells in a three-dimensional environment to simulate in vivo conditions. This technology provides more accurate results in anticancer drug efficacy testing and diagnostics, and has the potential to revolutionize cancer research and treatment. ...
How did graphene emerge as a dream material to revolutionize electronics and future industries?
Graphene is a thin, two-dimensional structure made up of carbon atoms that is 200 times stronger than steel, electrically conductive, flexible, and transparent. It can be applied in various fields such as semiconductors, batteries, medicine, and electronics, but commercialization is expected to be possible only after overcoming the limitations of mass production. Graphene, the...
Is scientific progress a blessing or a disaster? How should we balance the light and darkness of technological advancement?
This article explores the positive and negative effects of scientific progress on human society, both light and dark. It discusses how advances in science and technology can inevitably lead to problems, but that the responsibility lies with the human choices we make in dealing with them, rather than with science itself. Causes of problems in human society In the movie Dawn of the...
Your student’s home should be a relaxing retreat, but is your behavior causing stress and confusion?
Your student’s home should be a relaxing retreat, but your behavior may be causing stress and confusion for your child. It’s important for parents to avoid comparison and education shopping, and to be understanding and supportive of their child’s feelings so that they can focus on their studies. For students, home is a symbol of relaxation and a place where they are with...
How did radioactivity go from a scientist’s toy to a key tool in life sciences research?
The dangers of radioactivity to living things were not well understood in the past, but Hermann Joseph Muller’s discovery that radioactivity causes mutations turned it into an important tool for life science research. Radioactivity is dangerous. After the Fukushima disaster, radioactivity made Japanese seafood disappear from the table, and people became reluctant to have nuclear...
Vitamin K and Blood Clotting, What Do I Need to Know to Prevent Arteriosclerosis and Vascular Calcification?
Blood clotting is an essential defense mechanism in the body, and vitamin K plays an important role in this process. Vitamin K activates blood clotting factors and plays an important role in preventing vascular diseases such as hardening of the arteries and calcification of blood vessels. Vitamin K1 and K2 are highly active in different cells, and a balanced intake is essential. Blood...
In economics, is double differencing the best way to reliably assess the effect of an event when experimental methods are not available?
Double differencing is a useful quasi-experimental method for assessing the effect of an event, but it can lead to misleading results if the parallel trend assumption is not met. It is important to consider its limitations and caveats when applying it. In economics, it is often necessary to evaluate the effects of events for evidence-based policy discussions. This process is crucial for...
Are electric vehicles really an alternative to fossil fuels, or are hydrogen internal combustion engines a better solution?
In the wake of the third industrial revolution, electric vehicles have gained traction as an eco-friendly alternative, but they are not a fundamental solution to the energy problem, and they lack the charging infrastructure and consumer value. In contrast, hydrogen internal combustion engine vehicles are gaining attention as a potential solution to both environmental and consumer needs...
Can engineering innovation happen without management thinking? Why is management essential to the future engineering revolution?
This article highlights that advances in engineering technology cannot be successfully commercialized and marketed without the integration of business administration. It explains the importance of managerial thinking for engineering students, and suggests that business administration will play a key role in the future engineering revolution. The need for management in the...
Is TRIZ a Creative Problem Solving Theory with 40 Invention Principles to Overcome Technical and Physical Contradictions?
TRIZ is a creative problem-solving theory developed by Genrikh Saulovich Altshuller in the former Soviet Union that presents 40 principles of invention to overcome technical and physical contradictions. This theory can be used to radically solve complex technical problems. TRIZ, also known as Theory of Invention, is a theory for creative problem solving, created by Genrikh Saulovich...
