Benthic foraminifera, Hidden Gems in the Ocean
Benthic foraminifera are major sources of marine sediments. Though small in size, they exist in abundance and serve as foods for deposit-feeding organisms. Their shells, left behind after death, turn into sediments on the seabed. Take the benthic foraminifera appearing in global coral reef areas for example. Their remaining shells produce approximately 34 million tons of calcium carbonate annually. Apart from being key reef builders, they are also important components of the sand substrates of atolls and coral reef islands.
Benthic foraminifera are ecological indicators. Despite having a short lifespan, they are subject to environmental change. The ecological succession of benthic foraminifera reflect the impact of environmental change on animals that live on the sea floor, also called benthos. Since the early 1960s, they have been used as bioindicators for environmental pollution and healthy coral reef environments.
Benthic foraminifera are known as “microfossils” that provide a window on past marine ecology and environmental change. -The wide variety of their fossilized shells makes them extensively utilized to determine the age of rocks or strata, predict the climate of ancient earth, and understand the states of past oceans. For instance, the petroleum industry relies on the fossil data of benthic foraminifera to prospect for potential oil and gas reserves.
1. The Name Origin of "Foraminifera"
The term "Foraminifera" is derived from Latin, describing the porous shell of these organisms and their pseudopodia sticking out of the apertures.
2. The Habitat of Foraminifera
Foraminifera are widely distributed in various marine environments, ranging from the equator to polar regions, shallow to deep seas, substrate sediments, water columns, and other habitats where they attach themselves to plants and algae. Studies have also discovered benthic foraminifera in freshwater areas and in humid environments on land. They don’t have a shell or just have a simple-structured , inconspicuous shell. Molecular phylogenetic analysis indicates that these shell-less benthic foraminifera may have appeared earlier than the fossil records suggest, thus no trace left.
3. The Taxonomic Classification of Foraminifera
Foraminifera are primarily classified based on the composition and characteristics of their shells. For example, agglutinated benthic foraminifera secrete organic matter. Agglutinating sediment particles or animal remains will form their exoskeletons. Glassy and ceramic shells are typically composed of calcium carbonate. Classification can also be made according to shell shapes, chamber shapes, aperture types, and external ornamentation of chamber walls.
4. The Significance of Foraminifera in the Ocean
The fossil records of foraminifera are complete, spanning from the Cambrian Period to modern times. Therefore, the records are essential for stratigraphic correlation reference. Due to their high sensitivity to seawater temperature and chemical reaction conditions, they serve as excellent indicators of ancient climates and past ocean states. For instance, foraminifera with low levels of environmental tolerance in coral reef areas can function as bioindicators for healthy coral reef environments.
NLAC
The television documentary series "Trailblazers – Stories from the Laboratory" tells the story of scientists from the National Laboratory Animal Center and their contributions to animal testing and scientific research. Produced by Dong Tai Films in collaboration with the National Applied Research Laboratories, the program won Best Natural Science Documentary at the 52nd Golden Bell Awards in 2017.
Gut Microbiota and Us
The intestines, often referred to as the "second brain," contain the second most abundant neurons in the body. Their immune cells serve as the pillar of the body's immune system, and their inner lining can secrete up to 20 different hormones. Additionally, 95% of the body's serotonin is stored there. These functions are closely related to the resident bacteria in them. The intestines are more than "food processors."
There are hundreds of trillions of gut microbiota in the body of an adult, almost equivalent to the number of cells in the entire body. The DNA makeup of these bacteria is distinct from that of the human body, and they interact with our bodies by producing millions of molecules every second. Moreover, these microorganisms help regulate our metabolism, immune system, emotions, and overall health.
Gut Microbiota and Diseases
Over the past decade, scientists have discovered that the microbiota that coexist with us in the intestines are associated with the functioning of organs throughout the body. Imbalance of gut microbiota can lead to disorders such as inflamed bowels, diet-related obesity, and metabolic syndrome. The occurrence of neurological disorders such as Alzheimer's disease, Parkinson's disease, and depression is also related to imbalance of gut microbiota.
The composition of gut microbiota is highly complex. Due to their different genetic makeup from humans’, they will break down foods in the gut and produce various molecules. Moreover, they can act on the entire body through the bloodstream and the nervous system. Health-related molecules like butyrate, a kind of short-chain fatty acids (SCFAs), provide energy the body needs, boost the growth of probiotics, regulate the function of immune cells, help reduce inflammation, and even affect cancer cell differentiation.
“You Are What You Eat”
In a notable study, 21 pairs of identical twins underwent an 8-week dietary intervention. With their calorie intake controlled, one group consumed a whole-plant-based diet, while the other consumed a diet primarily consisting of meat and dairy products. The results showed significant differences in the gut microbiota between the two groups. The vegetarian group showed greater reduction in visceral fat and low-density lipoprotein cholesterol (LDL), also called bad cholesterol. Furthermore, an impressive result was that the vegetable-eating group’s telomeres, which are linked to DNA aging, were found to be longer than those of meat-eaters, which proved that they were healthier.
Supplementing probiotics with healthy foods alone may not have a lasting impact on the overall gut environment. Long-term changes in gut microbiota are best achieved through adopting healthy dietary habits.
Starting from Scratch - The Birth of Germ-Free Mice
Fetuses in the womb are germ-free. During natural childbirth, they acquire their initial microbiota through exposure to maternal vaginal flora. However, During Cesarean delivery, babies are also germ-free but subsequently acquire their microbiota through contact with their mothers’ skin or the environment.
Researchers at the National Laboratory Animal Center deliver germ-free laboratory mice by performing surgery in isolation boxes. They are then raised in a germ-free environment, with a "germ-free mouse model" established. Specific microbiota can be introduced through the feeding of one single bacterium or a group of bacteria to study diseases or physiological changes in the mice .
A New Hope for Precision Medicine - Microbiota Bank
Chang Gung Memorial Hospital, Linkou, has set up a "Microbiota Bank," which stores rigorously screened fecesthat provide healthy microbiota for fecal microbiota transplantation on patients with inflammatory bowel disease. Evidence suggests that the efficacy of certain drugs may be offset by specific gut microbiota , while some microbiota can enhance the effects of drugs. It is a promising trajectory for precision medicine in the future to analyze a patient's microbiota before administering medication and then transplanting beneficial microbiota as a form of treatment.
Next-Generation Probiotics – New Drug Development
Scientists worldwide have discovered bacteria that can aid the treatment of diseases, known as next-generation probiotics. One example is Akkermansia muciniphila, AKK bacteria or slim bacteria for short. They strengthen the intestinal barrier, reduce the entry of harmful substances into the bloodstream, and lower the risk of systemic inflammation. The bacteria have been found to be effective at treating metabolic-related diseases such as diabetes, hyperlipidemia, and obesity.
Magical Isolation Bubbles
Scientists have developed "isolation bubbles" that can keep away from bacteria, creating an incredible space as if by magic.
The Bubble Boy, David Vetter
David was born in 1971 with Severe Combined Immunodeficiency (SCID), making him highly vulnerable to bacterial and viral infections. To protect him, his doctors placed David in an aseptic bubble chamber that completely isolated him from the outside world. Every item he had touched had to be thoroughly sterilized. His life confined in the bubble came to an abrupt end at the age of 11 after a bone marrow transplant that caused him to be infected with an unknown virus. His story has called people’s attention to immune system disorders and has encouraged scientists to spare no effort to find possible treatments for rare diseases.
Isolation Wards
The purpose of isolation wards in major hospitals is to contain the spread of contagious diseases or quarantine patients with immune deficiency. This special ward is characterized by continuous inward air flow (for curbing the spread of contagious diseases) or outward air flow (for isolating patients with immune disorders) through highly efficient purification. Standard procedures for sterilization are required in order to prevent germs from getting in or out of the ward.
Isolation Boxes
Scientists have incorporated the concept of isolation into an operation-friendly space approximately the size of a desk called "isolation boxes" or isolators. They can control the movement of air and objects, thus used for the cultivation and separation of pathogens, housing infected laboratory animals, and studying immunodeficient or germ-free laboratory animals so that experiment results will not be invalid due to pathogen invasion.
TIRI
The Only Institute in Taiwan that Specializes in the R&D of Large-aperture Aspheric Lenses
Components for space technology are often objects whose export is internationally regulated, many of which are not available even with substantial funds. Therefore, here comes the need for independent R&D of key technologies. In terms of the optical system in a remote sensing satellite, the technology for large-aperture aspheric lenses is the key technologies, with challenges ahead. With forty years of experience in optical technology, the research team of the Taiwan Instrument Research Institute (TIRI) has studied over 100 papers in the relevant fields and managed to develop large-aperture aspheric lenses for the optical remote sensing system of FORMOSAT-5 over the course of approximately three years and three months. Currently, they are working on the R&D of the primary and secondary mirrors for FORMOSAT-8.
Let's follow the experts’ guide to the lenses and the structure of the optical system of FORMOSAT-5and pride ourselves on Taiwan's optical technology!
The Difference Between Aspheric Lenses and Spherical Lenses
The attribute of a spherical lens is that light rays near the optical axis and those near the edge of the lens do not converge perfectly onto the same focal plane, resulting in spherical aberration. The image of an object funneled at the focal point will be blurred out, leading to undesirable image quality. On the other hand, an aspheric -lens, whose curvature of the optical surface is variable, causes light rays near the optical axis and the edge of the lens to converge at the same point without spherical aberration, resulting in better image quality.
The Primary Mirror of FORMOSAT-5—Three Secrets behind Large-aperture Aspheric Lenses
Question 1: Why is the lens in yellowish color?
Answer 1: This is due to the use of a special material, "ZERODUR® glass," which will not expand while exposed to outer space, where the temperature difference is extreme. This glass material is commonly used in most remote sensing satellites and space telescopes.
Question 2: Why is there a hole in the center of the lens?
Answer 2: The lens is designed with a Cassegrain optical system, consisting of a concave primary mirror and a convex secondary mirror. The hole in the center of the primary mirror allows the light reflected off the secondary mirror to pass through and reach the image sensor at the back.
Question 3: Why is there a honeycomb-like structure at the back of the lens?
Answer 3: The large-aperture lens is typically heavy, and thus gets deformed easily due to its weight. This will affect image quality. After complex engineering calculations, a honeycomb-like design is finalized. This design not only increases the structural integrity of the lens but also reduces its weight, thus lowering the cost before it is launched into outer space!

TIRI
Introduction
The Taiwan Instrument Research Institute (TIRI) specializes in the development of key technologies in cutting-edge optics and advanced vacuum technology. TIRI offers an integrated, cross-domain service platform for the research and development of specialized instruments, making it a key partner for academic teams conducting groundbreaking research. TIRI is currently Taiwan's only research institute capable of providing customized services in specialized instruments for a wide range of academic fields. It is devoted to the development of "No.1 in Taiwan" and world-leading next-gen semiconductor processing equipment, cutting-edge systems in national defense, and remote sensing instruments. TIRI aims to train high-caliber technical professionals in the industry and continually improve the effective use of national resources for research.
Galileo Galilei (1564-1642): In 1609, I invented the refracting telescope to observe celestial bodies such as the Moon, the Sun, Venus, and Jupiter..
Sir Isaac Newton (1643-1727): In 1668, I invented the reflecting telescope, which has an advantageous simple structure. Large aperture telescopes are also easy to manufacture. The larger the aperture, the more light that comes in, making the observed detailsmore clear!
In 1672, Laurent Cassegrain invented the reflecting telescope, which is composed of two differently sized reflecting mirrors. The larger reflecting mirror is called the primary mirror and has a central opening, and the smaller one is called the secondary mirror. The catadioptric telescope used for astronomy today is derived from improvement of the Cassegrain telescope.
The Schmidt Cassegrain telescope was invented in 1931.
The Maksutov Cassegrain telescope was invented in 1940.
In 2012, TIRI utilized its 40plus years of optical component development experience to create the primary mirror for the FORMOSAT-5 satellite. With a diameter of 45 cm, it was the largest aspheric mirror manufactured in Taiwan.
A space telescope needs a large aperture to obtain clear images. If the telescope adopts a Galilean refractor design, it will become very large and cumbersome. With a Cassegrain modified telescope, after multiple reflections and refractions of light, the telescope can be reduced to a very short size or have an increased aperture to obtain good images. It is also lightweight and convenient to send into space.
Fresnel lens
A Fresnel lens divides the curved surface of a plano-convex lens into many small blocks, which are placed on a plane to reduce thickness. The biggest advantage of the Fresnel lens is that its size and weight are greatly reduced. Fresnel lenses also have magnifying capabilities. In addition, Fresnel lens principles are also used in the development of searchlights and lighthouses.
Pick up the Fresnel lens on the table and experience its magnifying effect!
Large Aperture Microscope Lens System for High Resolution 3D Brain Imaging (objective lens & tube lens)
The research team behind the High Resolution 3D Brain Imaging project at the Research Center for Applied Sciences, Academia Sinica carried out their research by improving on light sheet microscopy derived from the 2014 Nobel Prize in Chemistry. TIRI customized a large-aperture high-resolution optical microscope lens for "lattice light-sheet microscopy." Large-aperture microscopy lenses are extremely complex optical components, and their systems include both objective lenses and tube lenses. In order to overcome the imaging defects of a single lens, several lenses are combined into one lens to improve the imaging quality of the microscope.
The front end of the light sheet microscopy objective lens needs to be immersed in liquid used to preserve biological samples, and it must have a long working distance to capture a full 3D image of, in this case, a mouse brain. In addition to optical design, the environmental tolerance of this lens is more rigorous than an ordinary microscopy lens. The large-diameter microscopy system displayed here has a diameter of about 18 cm, which is much larger than that of an ordinary commercial microscope. It can be used to observe the neural structure and protein distribution of the brain.
TIRI has provided optical solutions with more than 45 years of R&D experience and has also customized special microscopy lenses with wide ranges of imaging and high spatial resolution. TIRI’s system can obtain a full layer of high-resolution images of a mouse brain in one shot, and can improve the imaging range and avoid time-consuming image stitching. It also can significantly improve the efficiency of imaging and research, which will help to further explore the brain and even solve human brain diseases in the future.

Considerations for Construction on Sloping Terrain
In densely populated modern cities, where flat land is scarce, many houses are built on adjacent slopes or directly on sloping terrain. Which side of the mountain would you choose to build on?
“Downslope” refers to the side of a slope where the geological layers align with the slope's inclination. This type of terrain is more prone to sliding disasters. Developers near sloping areas may excavate the foot of the slope and construct retaining walls to gain more usable land. However, during earthquakes or heavy rainfall, there is a high risk of slope movement, causing the collapse of these retaining walls and potentially damaging neighboring buildings.
Not all sloping terrain is unsuitable for development. Before commencing construction, it is advisable to engage with professional engineers for site exploration and geotechnical investigation to assess the geological conditions. Based on factors such as slope gradient and soil composition, appropriate slope stabilization methods can be determined. Constructing retaining walls is a common approach to stabilize slopes. During construction, attention should be given to drainage and protection of the slope through vegetation. However, even in areas suitable for development, maintaining a proper distance between buildings and retaining walls is crucial.
How to Minimize Earthquake Damage to Buildings
There are two main ways to reduce the impact of earthquakes on buildings: seismic damping technology and base isolation technology, which can be observed by considering the magnitude of acceleration displayed on the screen.
Seismic damping technology:
Seismic dampers can be installed in buildings to absorb vibrational energy during an earthquake, thereby achieving a damping effect.
There are various types of dampers available, typically installed in the beams and columns of the building’s structural framework. They can consist of single diagonal braces or take a V-shaped or inverted V-shaped configuration, taking into consideration the spatial flow and arrangement of doors and windows. The effectiveness of seismic damping in a structure depends on the number and placement of the dampers. Generally, it is recommended to install dampers in at least half of the lower floors of a building to achieve optimal damping performance.
Base isolation technology:
The principle of base isolation technology is to separate the building as much as possible from seismic forces and disrupt the input of energy, thereby reducing the damage caused by earthquakes. This is achieved by installing isolation pads at the base or lower floors of the structure to isolate the seismic forces and mitigate the disturbance caused by earthquakes. Generally, buildings that need to maintain functionality during earthquakes, such as hospitals or high-tech facilities, are designed with either structural isolation or equipment isolation.
In the case of the building structure on the left, which does not have a base isolation system, it will sway and shake during an earthquake, with greater vibrations as the floors go higher. On the other hand, the building structure on the right is equipped with a base isolation system at the bottom. During an earthquake, the structure behaves like an object floating on the ground, with only the base experiencing movement relative to the ground, while the upper parts of the building experience significantly reduced levels of vibration.
NCREE
Introduction
The National Center for Research on Earthquake Engineering (NCREE), established in 1990, provides earthquake simulation laboratories and large-scale static and dynamic experimental facilities. Its mission is to overcome the country’s research bottlenecks in earthquake engineering, enhance the level of earthquake engineering research, and assist with pre-earthquake preparedness, in-event response, and post-earthquake recovery. NCREE particularly focuses on the development of three core areas: structural seismic experimentation and numerical simulation; seismic design, assessment, and retrofitting of structures; and seismic damage assessment. It leverages the advantages of large-scale experimental facilities, experimental techniques, and earthquake databases, while also collaborating with various sectors including industry, government, academia, and research, and strengthening international cooperation.
In recent years, significant progress has been made in various aspects related to earthquake preparedness and response in Taiwan. This includes revising seismic design codes and regulations, seismic assessment and retrofitting, base isolation technology, and scenario simulation techniques. Efforts have also been made to strengthen earthquake early warning systems and safety monitoring technologies for effective emergency response. Additionally, there have been advancements in emergency disaster relief and rapid assessment techniques to facilitate post-earthquake recovery.
These efforts have yielded concrete results and practical applications. NCREE’s goal for the future is to gradually transform Taiwan into a resilient and sustainable homeland in terms of earthquake resilience.
How to Build a Sturdy House?
By imitating the framework of house beams and columns with the force of magnets, and using wooden boards as floors and walls, you can freely create your own house. Now, unleash your creativity and build a house that can withstand earthquakes!
What is a Weak Story?
When an earthquake occurs, a certain floor may be severely damaged or collapse while other floors have almost no damage. The damaged floor is referred to as a weak story.
Causes of Weak Stories
Common factors causing weak stories include inconsistent column alignment, insufficient wall quantity, or excessive height between floors.
If the ground floor of a building is excessively elevated without reinforcing columns or increasing wall quantity, it may become a weak story.
In a straight and continuous manner, the weight of a properly structured building can effectively transmit down to the foundation from the top floor, ensuring uniform and stable distribution of forces throughout the entire structural system.
When columns are not properly aligned, the path for weight transmission in a building becomes more complex, easily leading to damage at non-aligned points and forming weak stories. This increases the risk of earthquake damage and collapse.
Ground-floor commercial spaces often have fewer walls and columns in order to facilitate business operations, resulting in reduced seismic resistance for that floor and creating a weak ground floor structure.
Removal of walls due to interior design or other reasons on other floors of a building can also result in those floors becoming weak stories.
If illegal rooftop additions are made, the seismic resistance of weak stories becomes even worse.
Creating a Paper Model House
By crafting a simple paper model house, you can grasp the fundamental structure and characteristics of a building, as well as learn how to enhance its earthquake resistance. Come and give it a try to uncover the mysteries of "structure!"

Supercomputer TAIWANIA
Origin of the Name TAIWANIA: Taiwan Fir (of the genus Taiwania) is a native tree species in Taiwan known for its towering height. Naming the supercomputer TAIWANIA signifies its powerful computational capabilities.
How fast is a supercomputer? Taking TAIWANIA 2 as an example, it can perform up to 9,000 trillion floating-point operations per second. This level of computational power is equivalent to every person on Earth performing one multiplication operation per second. Even if they were to continue non-stop for 24 hours, it would take 13 days to complete. However, TAIWANIA 2 can accomplish it in just 1 second.
The speed unit for supercomputers is measured in floating-point operations per second (FLOPS), which represents the number of decimal-point calculations (addition, subtraction, multiplication, division) performed per second. The TAIWANIA series supercomputers belong to the Peta-scale range, with a unit of Pflops, which means to perform one quadrillion (10¹⁵) floating-point operations per second, or 1,000,000,000,000,000 FLOPS.

The Rise of Miniaturized Laboratories and Organ-on-a-Chip Technology
An Organ-on-a-Chip (OoC), also known as a Micro-Physiology System (MPS), involves the in vitro recreation of specific organ physiological functions to test drugs. Initially, this process was conducted alongside animal experiments. First, it simulates human cell physiology to confirm the accuracy of drug mechanisms. Subsequently, animal experiments are employed to verify what any side effects may be. In certain situations, organ-on-a-chip technology may gain regulatory approval to enter clinical trials directly, accelerating medical advancements.

By selecting materials with high biocompatibility and transparency and utilizing computer-aided design and precision manufacturing, microfluidic devices can be created. These devices uniformly mix fluids and generate a controlled microenvironment. Within the context of organ-on-a-chip environments, this setup mimics a blood circulatory system, facilitating dynamic cell culture conditions.
Microfluidics and Concentration Gradients
In micro-sized channels, fluids exhibit a unique physical phenomenon called "laminar flow." In laminar flow, initially free-flowing fluids that would normally mix with each other behave by forming layers with minimal mixing. Researchers leverage this laminar flow phenomenon by designing microchannel curves or lengths to set different concentrations.
Organ-on-a-Chip: In Vitro Organ Function Reconstruction
Organ-on-a-chip technology allows for the in vitro integration of human cells to simulate fluid dynamics, pressures, and interactions within organs. If successful, this technology can recreate beating hearts, flowing blood, or malfunctioning livers; multiple chips can even be connected to further replace animal experiments.
Heart Toxicity Testing Chip with Synchronized Heartbeat
Typically, cultured cardiac muscle cells do not beat in unison, making it challenging to simulate a heartbeat. Through the use of concentrically structured biochips, cardiac muscle cells can be cultured to grow in an organized manner, exhibiting synchronized contractions similar to a real human heart. This technology, with its heart-like contraction frequency, is applicable in assessing heart toxicity.
The 3Rs and Alternative Technologies in Animal Testing
To reduce unnecessary animal experimentation, a global movement known as the "Bunny Doesn't Cry" campaign emerged, aiming to restrict the use of animals in cosmetics testing. In reality, animal testing also pertains to verifying the safety of pharmaceuticals, vaccines, medical devices, health foods, and pet products. To ensure medical progress while safeguarding animal welfare, fulfilling the 3R principles of Replacement, Reduction, and Refinement has become the challenge to meet in order to transform next-generation animal experimentation science.
Replacement
Utilizing innovative cross-disciplinary technologies to develop alternative testing methods to replace animal experiments. For example, integrating AI algorithms with medical and animal experimentation big data.
Reduction
Modifying regulations that involve reliance on animal testing for safety assessments, thereby reducing dependence on animal experiments. This includes prioritizing the adoption of non-animal assessment methods through international collaboration, adjusting regulations, and addressing changes in product pricing and safety assessment methods following the elimination of animal testing – a responsibility shared by governments, industries, and the public.
Refinement
Enhancing the quality of animal experiments and minimizing those that are unnecessary. This involves implementing better harm assessment procedures and optimizing experiment designs and statistical methods to achieve animal reduction, enhance knowledge and techniques, protect test animals, strengthen bioethics education, and respect every single life.
